Do-it-yourself pipe bender: instructions for creating a universal tool + 59 photos

Each owner of a large garden plot or small cottage, at least once in his life (at least) may need a pipe bender - a device for bending a profile pipe.

For example, it can be a blank for a greenhouse frame or a canopy, a gazebo, or any other metal structures.

At the bases for the sale of metal, and at other production facilities, factory-made devices are usually used, but this pleasure is far from cheap. To save your budget for more pleasant expenses, it is more profitable to do the manufacturing of the device manually, on your own.

For this design, as they say, “a lot of mind is not necessary”, and there will be no shortage of details either, it is realistic to create blueprint drawings yourself.

Bender Options

You can bend the pipe in the “home” way, fill the pipe with sand, heat it with a red blowtorch or gas burner, and then bend the pipe. This method is not recognized as a priority among masters, it is laborious and does not provide sufficient accuracy, creases and deformations may also appear.

In order to get a perfectly bent pipe, in compliance with the norms and given parameters, not to cause damage to the source material, the craftsmen use specialized pipe benders in their work.

Lever type pipe benders have gained great popularity. This elementary invention works according to the “lever” principle - the force is concentrated in a certain place, and the bend merges with the shape of the template you created, which can most often be removed and replaced with another.

Most often, a set of such structures provides for a couple of additional templates for pipes of different diameters. There are similar assemblies in design, manual pipe benders, drone or crossbow, they allow bending short sections of round steel pipes, subjecting them only to cold working.

Crossbow devices are very compact, and are appreciated in the field of installation and utilities.

What is the work of a pipe bender

The principle of operation is quite simple, it consists in heating the pipe, the pipe is heated to red and becomes very plastic, malleable to changes. Each type of pipe bender has its own range of capabilities.

The main functions are the quality of the bend and the ability to bend pipes of different sizes and diameters.

With the help of additional rolling devices, bending of a larger diameter is achieved. The device operates with shafts, three of them are included.

Guides and push. The pipe passes through the movable elements, the degree of bending is set by the pressure of the pressure roller. If the radius of curvature of the finished product is small, the procedure should be repeated.

Pipe bending pattern

In most cases, the simplest option, suitable for absolutely all masters, even beginners, is a template made of wood. Boards are selected according to the thickness of the bent pipes, be sure to leave a supply of boards in a couple of centimeters.

To prevent the profile from moving off the template during operation, a slope is left at the ends. The template is rigidly fixed on the floor or other stable surface, next to the installation of the stop for the pipe.

The profile is inserted into the gap between the template and the stop, gently and gently press on its other end, pressing the pipe to the template. A winch or lever will make the job easier.

A huge plus of this process, cost savings and ease of execution.

Any device has disadvantages, and this method is no exception. The bend is not accurate, of poor quality, and the template will be disposable (only apply to one pipe diameter).

Pipe bender snail

In stamping the same blanks with a large circulation, small radius of curvature, a pipe bender-snail will be indispensable.

Its dignity in small size and ease of management. The disadvantage will be the limitation of the radius of the curve, but not of large sizes.

Rolling benders

The niche of versatility and practicality was occupied by hand-made devices - rolling benders (bending machines), on such machines you can make any bending angle.

The configuration is not particularly different from other models, they also have a base and shafts. A movable roller presses the pipe, and stretches its rotation of the drive shafts.

Pressing can be increased with a winch, levers or electric drive. However, for the production of a house, such a design is quite complicated in execution.

To reproduce such an assembly will require a lot of turning and welding. If you still decide to make such a model, it will last you a long time and will appreciate the functionality.

How to make a pipe bender with your own hands, the question in the modern world is quite relevant. To facilitate the task, you can find a photo of the pipe bender on the Internet to roughly understand how it should look.

There are also many drawings of a pipe bender that are easy to use. After reviewing all the information and evaluating your strength and the availability of the necessary components, calmly get to work.
