Hand-held bending machine for profile pipe

The need for bending strips or steel pipes arises in home masters often enough. To solve this problem, there are many options. For example, the corresponding equipment can be purchased at the store, however, the bending machine for the profile pipe can be manufactured with their own hands, but this approach will be cheaper.

Manufacture of the most simple

If you decide to do the above work yourself, then you can resort to the simplest solution, which involves a product that provides a certain bend radius of the pipe. Specialists advise the use of a template made by the handyman. With its help you can work not only with aluminum, but also with steel pipes. For carrying out the manipulation, it is necessary to prepare wooden planks, the thickness of which is greater than the diameter of the pipes used for bending. In the process, you will need to make a template by fastening the boards in any convenient way for you.

In order to exclude the slipping of the pipe during manipulation, the boards should be cut with a slight slope. If you decide to make such a simple machine for bending the profile pipe with your own hands, then it must be fixed to a table or working base in some reliable way. As close as possible to the template, it is necessary to strengthen the stop, in which the element will rest. On this we can assume that the pipe bender is ready.

Features of use

One end of the product should be placed between the stop and the template, and after, taking the other, with gentle smooth movements, it is necessary to bend over the workpiece. You can make a lever on the opposite end, for this it is recommended to insert a sufficiently strong rod into the pipe. You can use a method that involves the use of an element of a more impressive diameter. Do not attempt to bend the pipe from the center of the template, as this may cause damage to the product.

If a machine is to be manufactured for bending a profile pipe with one's own hands, it is possible to form a bend of a larger radius, but then the template will be made of plywood and hooks.

Making a bent pipe from hooks

Another fairly simple machine for bending the profile pipe with their own hands can be performed using strong metal hooks, which are installed on the plywood so that it is possible to form a bend line. As a plus of this model, it is possible to adjust the position of the hooks, thereby changing the bending line.

With the help of such equipment, you can work with products that are amenable to manual bending, as well as those pipes that are not so malleable for carrying out such manipulations. To do this, you can use a manual winch. If there is a need for manipulation, where the profile pipe will be used, you do not need to make a bevel when creating a template. The product is reinforced with several limiters.

Alternative options

If you decide to make a bending machine for your own pipe, the drawings presented in this article will allow you to make these works quite simply. A more complex model is a design consisting of templates and rollers. These elements should wrap the tube as precisely as possible. If you want to bend enough soft products, then the metal roller and the template can be replaced with blanks made of solid wood. For the production of rollers, you should use a lathe.

In the role of another solution is the use of plywood with a jigsaw. Thus, an element is created with a slope in a certain direction. The obtained circles of different diameters should be fixed in one roller, and after processing irregularities with the help of abrasive paper. When such a machine for bending a profile pipe is manufactured by one's own hands, the photo must be considered before the moment of commencement of work. In order to achieve higher reliability of wooden elements, they should be fixed with steel plates.

Manufacture of a pipe bender from rollers and corners

In order to form a pipe bender, it is possible to use blanks for rollers made of wood. These elements can also be made of bearings, however, if a clamping version is used, it is necessary to jam to prevent scrolling. From the step between the rollers will depend on important features of the design. If you decide to make a manual bending machine for the profile pipe, remember that the distance will be more impressive, the less amount of effort you will need to apply. However, in this case the radius of bending will be minimal. Side it is necessary to install steel corners, which will hold the pipe vertically. While relative to the axis of the rollers, it should be perpendicular. Otherwise, the pipe will be bent spirally.

The pressure roller needs to be tightened from below by the method of rotating a strip with a thread, which is cut in the central part. Gradually, the master must tighten the pressure roller, which will help to roll the pipe through the structure. If it is necessary to obtain a bend of a minor radius, it may take about 50 runs.

Another production option

If you need a hand-held machine for bending the PG-2 profile pipe, you can manufacture it yourself using shafts, steel profiles, a drive mechanism and a chain. If you have an engineering education, you can improve the design at your own discretion, adding functions. Shafts will be needed in an amount of 3 pieces, they must have rotation axes. It is with their help that the bending will be performed. The profile is needed for the frame.

Initially, you will need to prepare the frame. All parts are connected by welding, but it should be taken into account that it will not provide sufficient reliability when handling thick pipes. In order for the structure to be mobile and stronger, it is necessary to complete the fastening with bolts. If a hand-held machine is to be manufactured to bend the profile pipe by hand, then it must be remembered that the bending shafts are metal cylinders. Two of them should be fixed slightly above the level of the working surface. Then the third is set over them.

Features of work

The radius of bending of the pipe will depend on the pitch between the lower cylinders. After the shafts can be secured, the machine must have a system in the equipment that transmits the rotating forces. The most suitable option would be the use of a chain mechanism that can be bought on the market or borrowed from an old car.

Recommendations of the master

By the way about the aforesaid: if the chain you picked up separately, you should take care of the presence of gears, which should be three. Two are installed on the lower shafts, while the latter is somewhat lower. It is necessary to provide for the possibility of adjusting the position of the chain, which will allow it to be pulled if necessary.
