Creation of a manual bend by hand

Home masters often face the need to change the shape of the pipe, in other words, bend it to a specified size and in this case, many people remember that there is such a tool as a hand pipe bender that you can buy or you can build with your own hands.

Hand-type bender must be in the pantry of each master, as the need to make a round-shaped metal billet can occur at any time.

This tool has its own specific design features that allow it to easily bend a metal pipe to any required angular radii with minimal physical effort.

Today, for the profile and round pipes, hydraulic, manual, spring, dorn tubing types are used, which can be seen in the photo below.

In addition, there are also devices of crossbow, segment and electromechanical types.

Each such tool has its advantages and disadvantages, however, in any case, it is possible to make a metal pipe with its round form quite simply and quickly.

Any of these types of devices can be bought in a specialized store, and you can build by yourself, saving a significant amount of money.

In order to assemble a self-made pipe bender with your own hands, you must have at hand an appropriate drawing, material, as well as a certain tool.

assembly order The main purpose of the

device Recently, various profiled metal billets are very often used for making all kinds of fencing, various types of nets, and original garden furniture.

In addition, profile pipes can be found in the construction of car canopies, garages, greenhouses, as well as arbors in the country.

All these products consist of different elements, however, they necessarily include curved tubes.

To give the profile and round pipe the required shape, and use a tool called a pipe bender.

Such universal devices allow to make a bend of a profile and a round pipe under the most different angle, and at the minimum physical efforts.

This tool can have both hydraulic and electromechanical drives, however, the most common are devices with manual operation.

With this unit it is possible to carry out the necessary actions with small and large diameter pipes, regardless of their intended use.

The pipe bender for profile, metal, and also metal-plastic pipes can be found in the most different spheres of industry.

It is widely used in boiler houses, gas stations, in various industries, in construction sites, as well as in everyday life. With the help of it you can make a huge list of a variety of works.

It should be noted that, on an industrial scale, as a rule, professional pipe benders are used, which have either hydraulic or electromechanical drives.

In the household for domestic purposes, in most cases, use a self-made unit, collected from improvised materials with their own hands.

Of course, the easiest way to buy a pipe bender in any specialized store, however, if you make it yourself, you can save a significant amount of money.

In the photo below you can see the homemade arbor bender, assembled from improvised materials.

Structural features of

The design of the pipe bender, mainly depends on its variety and main purpose.

In any case, regardless of its design features, an indispensable element will be a rigid frame, as well as a hydraulic cylinder, metal bars and strong stops.

A homemade machine must also consist of these elements. In turn, the frame can be closed and open types. All the power load in this device falls on the hydraulic cylinder.

In the pipe bender, which is assembled by one's own hands, there must necessarily be a discharge device, which should be mounted on the end of the hull.

In addition, you need to think about the device bypass valve, as well as a convenient handle.

For the convenience of servicing the hydraulic cylinder, you should consider a cork device, through which you can fill oil if necessary.

It is also necessary to provide a reliable fixation of the working surface of the profile or round pipe.

The main bending force must provide a retractable type rod, which must have the property of returning to its original position. This can be achieved by installing a strong spring.

The upper and lower metal strips must have a welded construction.

A great value in this device is the emphasis, which must have a strong and reliable design capable of withstanding heavy loads.

As a rule, each type of pipe bender has its own specific features, which must reflect the corresponding drawing.

In order to make such a device with your own hands, it is necessary to have at hand not only a competently drawn up drawing, but also to buy all necessary elements of the design.

The video, which is placed below, details how to assemble a reliable pipe bender with your own hands from materials that can be bought freely in any construction shop.

Types of pipe benders

The most common benders are hand type, which can successfully cope with such tasks as bending pipes into arcs and rings.

This unit is relatively compact in size and light in weight, which makes it possible to move it from place to place, if necessary.

It will be indispensable for working with lightweight metal structures, for example, in the manufacture of greenhouse frameworks, gates or various awnings.

If you additionally use all kinds of mandrels in the manual type of the device, then the range of its actions can be expanded and already work with the profile pipe, transforming it into a profile bending.

These units can be purchased in almost all professional stores, and if necessary, produce by hand.

On an industrial scale, the most often used machines with electric drives, which have a high performance and a wide range of action.

Such devices can perform a variety of operations, but making it yourself is quite difficult.

For work with steel pipes, which have a large diameter, the enterprises use benders equipped with a hydraulic drive.

These devices have the ability to provide high power and easily withstand high loads.

Hydraulic-driven machines are generally used for laying gas pipelines and water pipes when a large amount of work is required.

Due to the fact that this machine has a special hydraulic installation, the operator practically does not apply any physical efforts at work.

Make this device with your own hand from improvised materials is almost impossible.

It should be noted that pipe benders are divided into stationary and hand-held devices, depending on the conditions of their operation.

For domestic purposes, as a rule, manual assemblies are used.

In turn, the manual types of machines can be attributed dornovy, spring, segment, as well as crossbow type of devices.

Principle of the

device At its core, the process of bending a metal pipe is quite complicated.

If it is not done correctly, then a variety of defects can occur on the material, up to the appearance of cracks directly at the bending points.

If you use a pipe bender for bending a pipe, you can perform a variety of operations on these blanks and give them the desired shape with minimal physical effort.

Dorn, spring and other types of pipe benders operate on the same principle. First, a working template is created, which indicates the required configuration for the workpiece.

Then, with the help of a stop, fix the pipe, which must be deformed and make a given bend along the contours of the template by smooth movements.

If the size of the workpiece is much smaller than the template in its dimensions, then it is done with a small piece of pipe.

Homemade arbor bender, assembled with its own hands, works on exactly the same principle as the professional one.

For domestic purposes, it is best to use a hand-operated bending machine that you can buy, or you can do yourself.

Buy a pipe bender can be in any specialized store, and how to make it yourself, described in the video below.

Assembly order

In order to assemble the pipe benders yourself, you must first of all buy all the necessary material and prepare the tool.

Also at hand, you should have a detailed drawing of the device with a description of its each element.

To begin with, the base of the machine is assembled from the available materials, while the walls of the pipe used must be of rectangular cross-section and have sufficient thickness.

In this pipe an opening is made for the main pulley, after which the excess part is cut off by the Bulgarian.

Next, you need to assemble the lever, for which you need to take the pin and weld it to one of its ends with a nut, and on the other a retainer.

After this, a handle is made, which requires the assembly of metal plates and a piece of rubber. The ready-made handle should be firmly attached to the pulley.

Next proceed to the overall assembly of the entire design of the tubing. To do this, put the plate on the base of the machine on the base of the device, then fix the main pulley.

After this, the hairpin is screwed in from the lock. The main pulley must be secured with a tightening bolt.

Once the pipe bend has been fully assembled, it must be tested, for which purpose it is necessary to take a pipe blank and try to bend it.

If the operation is normal, then the machine can be used for its intended purpose.

Of course, the easiest way to buy a finished product, however, it is not so difficult to assemble a reliable pipe bender yourself, and on how to do it correctly, it is told on the video that is placed above.
