How to make a manual pipe bender for bending a round pipe with your own hands? DIY pipe bender Manual pipe bender for round pipes up to 50.

Owners of private houses, as well as many home craftsmen, require pipes bent at certain angles for the manufacture of various elements of arched structures and pipelines. To do this, they use industrial, and more often homemade, pipe benders for round pipes. Professional factory pipe bending devices are expensive, so often such devices are made in-house, which allows you to save money.

Design and principle of operation of a pipe bender

The pipe bending procedure itself is practically not complicated, but requires special attention. During the bending process, it can receive defects in the form of stretching of the wall and a decrease in its thickness at the bending point, which will lead to a decrease in the strength of the pipe. Also, the location of the bend can change the configuration of the cut and instead of round section take the shape of an ellipse, which significantly reduces the internal throughput liquid passing through the pipe.

Design Features

To ensure that bending defects are minimal, when choosing or manufacturing a pipe bender for work, you need to understand how it works. The manufacture of a pipe bending device consists of three stages:

Such manual devices for bending tubular blanks can be mechanically or hydraulically driven, and these two options are perfect for a home workshop.

The operating principle of almost all pipe bending devices is the same. The workpiece is fixed in special device and under a certain force takes the required bending angle.

There are various pipe bending devices, and, naturally, each of them uses its own force system. For example, in crossbow or hydraulic type devices, a point force is applied to the bending section of the pipe.

According to another scheme, bending is carried out using several rollers, between which the workpiece is rolled, obtaining a certain bending angle. Pipe benders equipped with special inserts for pipes (mandrels) work according to this scheme.

What is a mandrel used for?

To understand the purposes for which mandrels are used, you need to know what can happen to a pipe during bending if you do not use a mandrel. For example, when bending a workpiece, two opposing forces act on some of its sections at the bending point:

Compression of the wall of the inner radius, in which the metal, deforming, forms a wavy surface (corrugation).
Stretching. In this case, the metal wall of the outer bending radius is stretched, due to which it becomes thinner. Naturally, this can weaken the strength of the pipe in the area of the bend by almost 50%.

If you do not use a mandrel, thin-walled copper, aluminum and other pipes made of soft materials can become especially deformed.

For the mandrel inserted inside the pipe before the bend, steel springs are usually used, selected to match the inner diameter of the pipes being bent. Sometimes the surface of the springs is coated with polyurethane to provide better stabilization of the pipe walls.

Types and production of bending devices

There are not so many ways to bend a pipe, but there are quite a few devices for performing these actions. a large number of. At the same time, they can be the most different types. In order to make a pipe bender for a round pipe correctly with your own hands, you can draw up drawings yourself or download them freely from the Internet.

Based on the principle of influencing a round pipe workpiece to bend it at a certain angle, there are various types of pipe benders.

Crossbow type model

These models of pipe bending devices are driven by hydraulic or screw drives. During the processing of the workpiece, the model is bent in the form of a crossbow arm, from which the name of the bending device comes.

The design of a crossbow pipe bender has some difficulties in manufacturing, but its power and technical capabilities are quite large. The device itself can be made with several functions, for example, using it as a bending machine and a hydraulic press.

Depending on the design of the rigid metal frame, the machine can operate in a horizontal position (the jack or other power device is located horizontally) and in a vertical position.

The design consists of a rigid frame and two rollers mounted on special racks welded to the platform. A jack is located in the center between the racks, and clamps are attached to the axes of the rollers, providing free fixation of the workpiece that is placed on them.

A punch for a pipe bender (shoe, template) can be made from old rollers, pulleys, or bent and cut along pipes.

The work of the crossbow machine is carried out in this way:

The pipe blank is placed on the rollers and secured with clamps.
A shoe (a template with a certain bending angle) is attached to the jack.
The jack presses on the center of the workpiece with a shoe and smoothly bends it to a given angle.

Using the same technique, you can make a small manual pipe bender, with which you can easily bend durable thick-walled pipes of medium and small diameter. For this purpose you will need to purchase hydraulic jack Not large sizes, two rollers, make a punch and a strong T-shaped nozzle from metal for the jack.

The entire design of the “crossbow” mechanism must have a large margin of safety. Otherwise, if the workpiece falls out of the fixing brackets under the pressure of the jack, the operator may be injured.

Roller system

Such pipe bending models are also called rolling models. Using this system, you can bend round or profile pipes, as well as steel reinforcement to a large radius. An ideal device for preparing arcs for canopies or greenhouses.

The main elements of this type of device are three metal rollers, matched to the diameter of the pipe workpiece being bent. The workpiece is placed on two outer rollers and the third, located in the center, is rolled along the pipe. Under its force, the part gradually bends, acquiring a certain bending radius.

The system can be driven by a hand crank or an electric motor through a special gearbox for a pipe bender. The quality of the resulting product processed using this device is quite high, and the pipe itself, in contact with the metal rollers, receives virtually no damage.

The advantage of a rolling pipe bender is its small sizes, thanks to which the tool takes up little space in any home workshop and can be easily mounted on a workbench or wall. And due to the fact that it is made entirely of metal, the workpiece can be heated during bending to facilitate work blowtorch or a gas burner.

The simplest device

For urgent work that requires a manual round pipe bender to quickly bend an angled elbow, such as for a home plumbing project, a simple bending device can be made using the tools at hand. To do this, you should prepare a lever from a piece of metal round pipe with a diameter of approximately 32-42 mm or thick, preferably smooth fittings. The length of the lever should be between 1-1.5 m, depending on the workpiece being bent.

A ring of thick-walled pipe trim approximately 30-40 mm wide is welded to one end of the lever. The inner diameter of the ring must be larger than the outer diameter of the workpiece prepared for bending.

Instead of a ring, you can weld two rods from a thick smooth rod to the lever. The rods are welded perpendicular to the lever and parallel to each other. The distance between them must be greater than the outer size of the workpiece prepared for bending.

The bending process is carried out as follows: P

The workpiece is laid on a hard, flat surface, it can be asphalt, concrete floor, reinforced concrete panel or thick board.
The tubular blank prepared for bending is threaded into the ring of the manufactured device or inserted between its pins, after which, acting on the lever with muscular force, it is bent.

Winding machine

Pipe bending machines of this type differ from other bending devices in that the pressure roller presses the workpiece directly against the template itself, as if winding the pipe around it. This allows you to bend ring-shaped and spiral parts from workpieces, which is completely impossible to do on conventional pipe bending machines.

During operation, the roller itself is stationary, but the template, to which the end of the workpiece is rigidly attached, rotates around its axis, winding the pipe around itself, which is why machines of this type are called winding machines.

The drive on such devices is most often electric, since twisting the pipe into a ring requires a lot of force. The mandrel for the template must be removable, otherwise it will be quite difficult to remove the spiral-curved workpiece from it. The template can be made of wood, PCB or metal.

The advantage of the winding machine is its simple design, but the disadvantage is some limitation in the size of the template and the need for a powerful lever.

Wooden conductor

This design can be considered a break-in device, and the difference is that there is no pressure roller. To make this device you will need thick plywood or boards; you can use a workbench or a massive chipboard slab as a base.

A template is made from a thick board, one side of which is rounded to a certain radius. It is rigidly fixed to the edge of the workbench in such a way that the workpiece prepared for bending can be freely wrapped around it.

The end of the workpiece can be fixed with a primitive wooden stop made of timber or by cutting the same board from which the template was made. The pipe is bent using muscular force smoothly, without sudden movements, then its damage will be insignificant, and the acquired geometric shape It will turn out accurate and even.

To prevent the bent part from jumping off the template (punch), it is advisable to make a semicircular recess around the perimeter of its rounded part, treating the end with a round rasp.

Fixing the pipe on the template can be done in another way by stuffing a rounded piece of plywood on top of it, which should protrude beyond its edge within 6-10 mm. True, this option is well suited if the tube has thin walls, since bending parts with thick walls requires more powerful forces, and the wooden punch may simply collapse.

Before you start bending the pipe, it is recommended to pour dry sand into it and plug both ends with wooden plugs.

This will help avoid the appearance of waves (corrugations) on the workpiece inside curved section, and large stretching of the metal on the outer wall of the bend.

Of all the existing pipe bending machines, the most widely used is the self-made pipe bender, which operates on the principle of a rolling device. This model of pipe bender has virtually no disadvantages; it is light in weight and size, can be easily transported and takes up little space during storage.

Pipe bender KACHOK - QUALITY OK!

Arched and dome-shaped roofing structures came into fashion with the advent of flexible materials for roofs This is the well-known polycarbonate, soft roof, various filled plastics, flexible slate and corrugated sheets. The need and opportunity arose to assemble lightweight and portable structures, roofs over shopping pavilions, roofs over swimming pools and canopies. What could be simpler? Use a “KACHOK” pipe bender to bend profile pipes into an arc and attach cellular or monolithic polycarbonate to them.

I would like to tell you more about the popular pipe bending machine “KACHOK” for profile and round pipes, which is suitable for many jobs and performs almost all necessary operations. It was developed for small businesses and blacksmith shops. Please note that the pipe bender is compact and heavy. Its weight in the package is 45 kilograms. Dimensions: 450x450x540 mm. You can't tell from the photo, it looks attractive and even beautiful. The entire body of the pipe bender is designed in such a way that by installing it on the table and screwing it to the table with four bolts (not included in the kit) through the holes in the base, you can immediately start working.

What kind of work can be done on the KACHOK pipe bender? You can bend profile pipes of 15, 20, 25, 30, 40, 50 mm and even 60x30 mm into an arc. Most often, arcs are bent, which are subsequently used for greenhouses, canopies, canopies, fences, gazebos, pergolas and other complex non-linear structures.

Rollers for rolling on a pipe bender profile pipe are located on the drive axles. The shafts are mounted on bearings. Sprockets and a chain drive are installed on the shafts. If you rotate the handle, the rotation is transmitted to all axes, so to speak, “all-wheel drive.” It is easier to twist and pipe slippage is practically eliminated. In addition, the roller shafts have a fine notch, which provides additional adhesion of the rolled pipe to the rollers.

This pipe bender can easily be converted into an electromechanical one.

The pipe bender kit also includes rollers for round pipes. Rollers for pipes with a diameter of 20, 25, 30 mm. A round pipe is rolled easily and the walls remain smooth without dents or corrugations.

You can work with a strip of maximum 40x10 mm. The strip rolls perfectly on these rollers. When I needed hoops with a diameter of 1 meter from a strip of 30x4 mm, I made them easily. The edge strip is rolled onto external rollers that come complete with the pipe bender. The maximum you can work with is a strip of 30x4 mm.

The tests we carried out revealed the good performance of the pipe bender and the high quality of individual elements. Simple and reliable design. Jock - QUALITY OK!

Servicing a pipe bender is not difficult. It is necessary to periodically lubricate the pressure roller screw and sprockets. Any lubricant is suitable, LITOL can be used.

When working on a site or in a garage, quite often it is necessary to bend several pipes along one or another circle. Or, as an option, make even steel strips semicircular. For this, a device such as a pipe bender is used, but purchase factory model to perform a couple of operations is not a cheap pleasure. It’s easier to make a simple pipe bender with your own hands that can bend a pipe to the required dimensions. We will get acquainted with the simplest and most popular versions of this design today.

What are pipe benders used for?

Profile pipes with various cuts are considered the most popular today metal products and are used in the construction of greenhouses, sheds, garages, for creating fences, during pipeline laying, and so on. And in the manufacture of most of these products, pipes must be bent at one angle or another, and without special equipment there is no way to cope with this.

So, a pipe bender is special device, through which, in most cases, pipes are bent, and the bending angle can be different (within 0-180 degrees). The drive of a modern pipe bender is often electromechanical or hydraulic.

Note! Using the device described in the article, you can bend products of any configuration (boiler, gas and water supply; moreover, pipes can be either steel, copper, aluminum or metal-plastic).

The scope of application of a pipe bender is quite wide - it can be found on construction sites, when creating heating/water supply networks, at industrial facilities, etc. A self-made pipe bender is irreplaceable thing on the farm, which can be used for the most various works. If, for example, you intend to install an air conditioner yourself, equip a ventilation or heating system, then it will not be easy to do without this unit.

How does a pipe bender work?

The specific design of the device depends, first of all, on its purpose, however, a pipe bender must include:

frame;
a pair of pipe stops;
hydraulic cylinder;
strips (upper/lower).

Note also that the frame can be either open or closed. As for the hydraulic cylinder, it is the main part of the device that performs the power function.

Also in the do-it-yourself pipe bender circuit there is a pressure device, which is located on the back of the body; The bypass valve screw and handle are located in the same place. But on top of the cylinder there is a plug through which oil is poured inside and its level is checked. The unit strip located below is screwed onto the thread located in front of the housing, and then pressed with a special fixing nut. Additionally, the bar is secured with a lock and a pair of screws.

For manual reinforcement, a retractable rod is used, which returns back thanks to a spring located in the cylinder. The pipe bender bars are made as a welded structure. The transverse plates have holes through which stops are installed. At the bottom of the case there are also threaded holes for mounting bolts, adjustable in height.

Note! The stop is made in the form of a pin, and the stops, which are located at its ends, are inserted into the holes on the slats. The bent product will rest on the stream located in the middle of the stop. The bending elements are made of precision cast steel.

When considering a pipe bender with your own hands, one cannot help but note the fact that profile pipes with thin walls are used in last years becoming increasingly popular, moreover, they make it possible to create durable and attractive designs, as well as save on construction work. It is from these pipes that greenhouses and various canopies are made today. What is the difference between a profile pipe and an ordinary one? First of all, the cross section, which in this case is not round, but oval, rectangular or square. This is precisely what explains the design features of the pipe bender for of this type pipes - rollers must be of the same cross-section as the products being bent, otherwise the cross-section of the latter may be deformed.

Types of pipe benders

Using a manual pipe bender, you can bend rings and arcs. Such a device weighs relatively little (about 65 kg), thanks to which it can be transported to the work site with small metal structures (the same greenhouses, gates, canopies). Here are the main characteristics of materials that can be processed with a manual device: a round pipe with a cross-section of 3 centimeters, a square one - 4x4 centimeters, a rod - 1.6 centimeters, a strip - 4x1 centimeters and, finally, a square - 1.6x1.6 centimeters.

Thanks to various types of mandrels, the range of processed products can be expanded, and the pipe bender, in turn, can be turned into a profile bender. Price hand tools is such that it can be purchased or made with one’s own hands, even for minor productions.

As for electric pipe benders, they are used in industrial scale when working with products of various sections. Such units are very productive, which is determined, first of all, by additional functions, including rotation of the rollers in two directions at once, the use of foot pedals, and adjustment using the control panel.

The capabilities of electric pipe benders include bending arcs from square (8x4 centimeters) and round (3 centimeters) pipes. In order to match the cross-sectional configuration and diameter of the products, the devices are equipped with special replaceable mandrels for each specific case.

A hydraulic manual pipe bender is considered more modern, the strength of which is such that it allows processing fairly large steel products. It is this option that is desirable to use for water or gas pipelines. This pipe bender’s drive is equipped with a special hydraulic unit, which distinguishes it from a conventional device (the operator’s work is noticeably easier).

Hydraulic devices can be of several types and can be used for various pipes and fittings. Thus, a portable pipe bender (TPB) can be used for solid steel pipes, as well as for round products (we are talking about the bulldozer method, when the pipes are not filled with sand or other fillers). There is also a manual unit (RGU), with the help of which water and gas pipes, reinforcement or, again, rolled steel.

Note! From the point of view of operating conditions, a pipe bender (including with your own hands) can be manual or stationary. Representatives of the first group are more suitable for domestic use, while representatives of the second are more suitable for enterprises where bending pipes or other products is required.

Operating principle of a pipe bender

At first it may seem that there is nothing super complicated in bending pipes, but in reality this is not entirely true. If handled incorrectly, you may encounter all sorts of defects, including crushing (which can cause a change in diameter) or stretching of the thickness at the bend (due to this, the strength characteristics of the pipeline may suffer). For this reason, the device must be selected correctly, knowing the principle of its operation - this way you minimize possible defects.

The very principle of operation is as follows. At the beginning required size semicircles are drawn on folded boards or pieces of particle boards, after which they are cut along the line and fixed with nails on the floor, wall or fence. It must be remembered that this shield should be slightly thicker than the product being bent (about two to three centimeters). A stop is fixed from the edge of the board in the side part. The edge of the pipe is inserted between the latter and the template, and then a smooth bend is made in accordance with this template (for this you need to grasp the second end of the product with your hands).

Important information! If we are talking about a short pipe or a small rod, then the second end is extended by cutting a pipe that is suitable in diameter.

We also note that there are quite a few complex solutions problems with pipe bending large diameter, however, they require plumbing skills and the use of professional equipment. Making such a pipe bender yourself is not only difficult, but also expensive - it is much easier to purchase a manual unit that has already been used.

A simple pipe bender for ordinary pipes with your own hands

To assemble a simple pipe bender with your own hands, you only need what you can find at any summer cottage. More specifically, you will need:

wooden shield;
two small bars;
large hooks;
several strong boards.

Draw a semicircle on the finished shield according to which the pipe will bend. If the unit will be used several times, draw a couple of semicircles at once. Next, nail bars or boards vertically from below (they can help with inserting the pipe and fixing its ends). After this, attach large hooks along the semicircle. This unit is quite convenient, but its disadvantage is that the hooks will have to be re-weighed each time in order to receive different angles bending

Making a pipe bender designed for working with profile pipes with your own hands

For this kind of pipes, the design described above is no longer suitable. For this reason, you will need a special roller pipe bender with your own hands. If you look at the drawings and step by step instructions, then you can quite easily make such a machine with your own hands.

Materials you will need:

pre-made frame made of steel profile;
rollers;
jack;
three rollers.

After preparing everything you need, you can proceed directly to the manufacturing process.

Step one. Make metal carcass. At the bottom you can additionally weld fasteners for fixation on the countertop. After that, place a pair vertical supports: side and center. On the opposite side (where there is no support), the profile will rise, and therefore it needs to be bolted. This part will be lifted using a jack.

Step two. Weld the shafts to the finished frame. Two are on the sides, while for the third it is necessary to prepare supports in advance. The shaft will be attached to the latter.

Step three. Weld the handle, made from a steel pipe, to the central shaft. This handle will be used to bend the product.

Step four. Fix two shafts, as well as rollers, between the shafts on the sides and the central one so that the product being bent does not move. The fact is that this way the pipe will not move much, and therefore the work will be done with the utmost care.

Step five. At the end, install a jack under the movable part of the profile (the one with the roller). The jack, by the way, can be either a simple rack or bottle jack. If necessary, secure it to the structure.

Note! Take careful measurements before starting work. Draw a diagram, check how well the parts are welded together. In addition, we recommend that you watch the video below.

Manufacturing a compact snail pipe bender

To make a pipe bender with your own hands, you can use ready-made design drawings. Check out several options, balance their complexity with your capabilities, availability of the required skills and equipment. So you can choose the most optimal design. So, check out several more options for pipe benders that you can easily assemble with your own hands.

Let's start with the fact that in order to bend profile pipes correctly, you need to clearly understand what the physics is this process. As a rule, hand-held devices use a so-called circular bend, due to which the risks of damage to the product, cracks or creases are minimized. To bend a pipe in such a unit, you need to fix the pipe in it, and then press the lever. The product will bend as it rolls over the roller, which in turn presses it against the main wheel.

As for necessary equipment and materials, then you will need:

sheet of metal 6 mm thick;
ruler/tape measure;
Working wheel;
hammer;
pressure roller;
corners made of steel, with dimensions 5x5x0.25 centimeters;
welding machine (and skills to work with it, of course);
a piece of thick pipe with a diameter of 2.5 centimeters;
Bulgarian;
axes of rotation;
washers, nuts;
a piece of metal rod with a square cross-section (2x2x4 centimeters).

Note! When constructing a pipe bender with your own hands, be sure to follow safety requirements! This especially applies to welding and cutting metal!

How to calculate a structure. Drawing

Before you start making a pipe bender with your own hands, determine at what radius you will need to bend pipes most often. The dimensions of the impeller will depend on this (they should be the same as the inner radius of the finished elbow).

The drawing presented above was created for profile pipes whose diameter does not exceed one inch. Using this unit, it will be possible to obtain a bending radius of up to 12.5 centimeters (this is 1/2 the diameter of the impeller). But if you require other bending parameters, use the appropriate calculation method.

So, the main size of the fork is the distance between the axes of the roller and the impeller (here a = 200 millimeters). This interval was chosen in this case taking into account the fact that the maximum diameter of the profile pipe will be 25 millimeters, but we recommend adding a few more “reserve” millimeters.

Here is the formula for calculating the distance between the axes:

d + r1 + r2 + 2= a, in which:

d is the exact diameter of the product;
r1-2 is the radius of the roller/impeller.

Note! If the design of the future unit provides for the presence of a kind of rivulet pulley, then measure based solely on the lowest point of this element.

To determine the size of the fork, take 10 millimeters as the gap between its base and the roller, and then add another 30 “spare” millimeters. But to determine the internal clearance, add one or two millimeters to the thickness of the wheel.

Important information! For a more versatile design, make several holes on the sides of the fork. When you move the roller axis, you will change the distance between the surfaces of the rotating elements.

How to make such a pipe bender - a detailed guide

As you can see from the diagram presented above, the design consists of:

thick iron plate (base);
forks;
impeller;
and finally the video.

To make a pipe bender with your own hands, follow the sequence of steps below.

Step one. First, make a roller and impeller. If you have lathe, this is very good, but in the absence of such equipment, these elements can also be manufactured without any difficulties. For a reasonable fee, a specialist will quickly turn your pulleys.

Note! Don't skimp on creating movable parts! They must have a groove for a pipe of maximum diameter, in addition, the roller must have a seat for a rolling bearing.

If necessary, adjustments can be made to the design of the knee surface; The roller/wheel groove is shaped. When the roller rolls, it will leave a mark on the outer surface of the knee, while the wheel will leave it on the inner surface. To make work easier and reduce the overall cost of the structure, you can install two ball bearings of the required dimensions instead of the roller.

Step two. Using the same machine, it is necessary to make an axis for the roller and impeller. It is important that the thickness of the elements matches internal diameter the bearing you are using. As for the length of the axle, it should be the same as the outer width of the fork. The length of the wheel rotation axis will be slightly larger, since the thickness of the base plate of the unit will also be taken into account. If you refuse to install bearings, you can thereby significantly reduce the cost of the process, and in this case the role of axes will be long bolts with nuts. Be that as it may, remember that working with such a device will be much more difficult.

Step three. After this, take a sheet of metal, cut out the back wall and side surfaces of the fork from it; in addition, you will need a piece of pipe with thick walls, which will serve as a lever.

Step four. In accordance with the diagram, make holes in the fork for the roller/wheel.

Step five. Weld the fork elements. At the same time, make sure that the right corners of this product are made especially well.

Note! It is better not to attach the lever end-to-end to the fork, since this kind of fastening will be unreliable due to the large forces applied. The best option– drill a hole in the back wall where the end of the pipe will subsequently go. If you scald such a compound using welding machine, you will end up with an extremely strong joint.

Step six. We continue to assemble the pipe bender with our own hands. So, now arm yourself with a grinder and use it to cut out the frame. After this, drill a hole in it of the appropriate size for the stationary wheel axle.

Step seven. If necessary, press the bearing into the roller.

Step eight. Place the roller in the fork and then secure it with nuts or a welding machine.

Step nine. Place the assembled fork on the base, fixing the wheel axle in the same way as when installing the roller.

Step ten. Weld a piece square section- this will be a kind of fixation of the workpiece.

Finally, make holes in the corners of the base to install the unit to the workbench. Don’t forget to clean the welding areas so that the final structure looks more attractive. Also paint the pipe bender with enamel to protect it from rusting.

Another design of a bending machine

Here, as you can see, the roller is pressed using a threaded drive. In this example, a hydraulic jack will be used and manual drive, in which elements of the gas distribution mechanism will be present (we are talking about those in car engines). And one more thing: do not forget about personal safety! Always use personal protective equipment when working!

Now - directly to the process of making a pipe bender with your own hands

Step one. First, make the pressure shaft and support shafts. If you do not know how to operate a lathe, you will need the help of a professional. It is important that the rollers have shanks necessary for mounting the sprockets.

Note! The chain, as well as the sprockets, can be anything.

Step two. Attach bearing supports to the shafts, secure the gears to the keys.

Step three. Weld the frame of the future pipe bender. First of all, make a square frame with support legs, and then install a structure on it, through which the plate with the roller will move.

Step four. In this case, the plate will be a channel (H- or U-shaped). To install the pressure shaft, make holes at the edges of the plate taking into account the dimensions of the bearing supports.

Step five. Hang a piece of channel with a roller on four springs on top of the frame (pre-weld nuts in the corners that will serve as mounting loops). Then finally install the hydraulic jack.

Step six. Secure the drive shafts to the lower frame.

Step seven. Place the chain on the sprockets and press down on it to determine where the tensioner will be located. Install the latter on the frame of the structure.

Step eight. Install the handle to rotate the shafts of the structure. We recommend using a handle with a rotating tube to make it easier to work and to avoid calluses on your hands.

Step nine. You can treat the finished pipe bender with your own hands with a special rust converter and then paint it.

In the end, all that remains is to check the resulting design for functionality. That's all, we hope that by following our instructions you will definitely get the desired result! And at the end - another thematic video material.

Good luck with your work!

Video - Making a simple pipe bender

Owners country houses or personal plots When updating a pipeline or carrying out any construction work, robots are often faced with the need to bend a round or profile pipe at a certain angle.

If such a process has to be carried out frequently, it is better to purchase special equipment. But if such a need arises rarely, then you can make pipe benders for a round pipe with your own hands using simple manipulations; video lessons and drawings of this design will be presented in the article below.
In this publication we will talk about how to make a pipe bender at home from improvised means for bending round and profile pipes. However, before starting the description step-by-step production, in the introductory part, let's look at what this tool is and for what purposes it is used on the farm.
What is a pipe bender and what is it for?
It is a design that makes it possible to bend profile or round pipe materials at the desired angle. They are divided into:
hydraulic;

mechanical;

manual.

The first type copes with bending large sizes, mechanical models are used for medium-sized ones, and manual ones are considered ideal option for diameters up to 3 cm and profiles up to 4 cm.
According to their own design features, functionality and operating principle they are divided into:
crossbow;

segmental;

spring.

The operating technology of any pipe bender is the ability to correctly bend the product to the required radius. If no attention is paid when bending Special attention quality of the result, then homemade designs will cope with this task 100%.

Made from a metal pipe and nut
This type of bending device is considered the most elementary. It is made from a piece of rigid round pipe (metal rod) with a nut attached at the base.
We make a template for the future bend from wire;
We take measurements of the template and transfer them to the pipe;
The pipe is installed on a flat floor with a hard surface;
The pipe is inserted into the pipe bender nut, comparing its direction with the measurements on the pipe;
With your foot, resting on the pipe that is on the floor, we press it harder, and bend the second edge, slowly pulling the handle of the pipe bender towards you. Such manipulations allow it to be bent by 10˚.
Moving the pipe along the hole of the nut, the procedure is repeated several times until the bend eventually takes the desired shape.

Wood pipe bender
To bend a round pipe yourself, you can make a pipe bender from wood with your own hands. From a technical point of view, such a device is the simplest; operation does not require additional parts, such as a hydraulic cylinder.
We start by knocking together several boards of dense wood and cutting out half a circle of the appropriate diameter. For cutting, you can use the simplest hand saw, the main thing is to ensure that the slope is maintained closer to the base.
The resulting workpiece is attached to solid foundation in the form of a tabletop or wall. An additional block of wood is also attached to the base to create additional support.
When choosing a tree, pay attention to the fact that its thickness must be greater than the diameter of the pipe, otherwise during the process of bending the sample, it may slip and cause injury.

To easily make a wooden pipe bender for a round pipe with your own hands, you can familiarize yourself with the video lessons below. This will help you understand all the nuances of this process.
How to work with it?
We place the pipe in the recess between the wooden semicircle and the thrust block and carefully begin to press on it with reverse side, bending to the desired shape.
The main thing is that it fits easily into the opening. Given wooden device bends aluminum and steel products well. Moreover, its production requires minimal costs.
Pipe bender made of metal hooks
To make it you will need to carry out the following simple steps:
buy high-quality metal hooks at any hardware store;
we fasten them on a stable base in increments of no more than 5 cm. However, the distance of one hook from the other will depend on the size of the product that needs to be bent;
as a result we get a semicircular template;
An additional stop is attached to one side of the device.

The bending process will be reminiscent of working with a wooden template, but in this case there is no need to make a new template for different diameters; just move the distance between the hooks.

It consists of rollers and a cylinder and is a more complex unit. But it allows bending at any angle up to 360˚. In fact, it is possible to create a pipe bender for a profile pipe with your own hands, as similar as possible to technical specifications, for hydraulic equipment.
The sample is fixed using rollers, and a freely moving cylinder gently bends it to the desired angle. To make such a unit with your own hands you will need:
two steel plates 30 cm long and no more than 10 millimeters thick;
four steel corners with shelves measuring 5x5 cm;
from wooden planks the template is knocked down, the thickness of which should not exceed 3 cm;
the steel plate is attached to the underside of the wooden template;
on the base, in order to give greater strength to the structure, it is advisable to attach corners;
a second steel plate is attached to the top;
in the latter a hole is made of the same diameter as the screw that will be installed there;
the bolt serves as a support for the bent pipe;
Angles and rollers are attached to the top plate, which are oriented inside the pipe bender;

This type of design makes it possible to bend any profile product at any angle.

Rules for using homemade manual pipe benders
In order for the manufactured device to perform its job efficiently and correctly, you need to adhere to several simple rules for its use:
If seam pipes are offered for bending, which are used when installing a pipeline, then the seam should be placed towards the bend;
In case of bending large diameters It is recommended to work with a partner;
During the process, use protective equipment and do not forget to adhere to safety regulations.

Summarizing all the above information, we can say one thing: building a pipe bender yourself is a feasible task. And you can bring it to life if you have minimum quantity free time and money.
