Metal is a widely used material in various fields of economic activity. There are several ways to handle it. One of them is metal bending .
Benefits of this technology .
When applying the bending process, it is worth remembering that metal of various thicknesses will bend at an angle, which requires an accurate calculation to obtain the required structure. The advantage of this technology is the following indicators:
- The structure of the metal changes minimally, in contrast to exposure to high temperatures during welding or cutting. This helps to preserve the strength of the material and its quality characteristics;
- Ability to obtain a seamless structure while maintaining anti-corrosion properties;
- When bending pipes, the advantage of bending is expressed in the absence of additional seams and ensuring the integrity of the structure.
Bending types.
Manual metal bending is suitable for thin materials and requires some effort and care. Hand bending requires the use of a hammer, pliers and yews. Thin metal is bent with a wooden mallet.
The more common way to bend sheet metal is to use special tools and machines. The simplest bending machine can be made by hand. The device is a frame structure with wooden or ground shafts with a roller mechanism located at a certain angle in relation to each other. The main thing, when making a home-made machine, is to correctly calculate the bending angle and place the working parts of the unit accordingly.
Modern industrial machines designed for metal bending are capable of processing a large amount of material in a short period, while performing multi-contour bends in one operation.
Bending of metal pipes is carried out using elementary devices in the form of fixed pins or on a factory machine. When performing this procedure, it should be remembered that the pipe may flatten, burst or bend more than necessary. To prevent this situation, it is recommended to fill the pipe with sand or other free-flowing filler. It is better to warm up thick-walled pipes of large diameter with a blowtorch or a cutter.
