What factors affect the rebound when operating the profile bending machine
Profile bending machine is a kind of efficient processing equipment used for bending various special-shaped steels such as angle steel, channel steel, I-beam, flat steel, square steel, round steel, etc. During bending, according to the requirements of the component shape, the profile bending machine equipment and certain tools and molds can be used to bend the plate or steel into a certain shape.
The profile bending machine can complete the end pre-bending and bending forming in one loading, and the bending shape is diversified. The profile can be bent into the required circular, arc, spiral, elliptical, U-shaped, flange shape, etc.

What factors affect rebound when operating the profile bending machine
1. The higher the yield strength of the material, the greater the rebound.
2. The ratio of the bending radius r to the material thickness t, the larger the value of r/t.
3. The larger the deformation area, the greater the rebound.
4. The friction between the material surface and the mold surface affects the stress state of each part of the blank. In most cases, the tensile stress in the bending deformation zone will be increased, and the rebound will be reduced.
Conclusion
The profile bending machine has compact structure, low energy consumption, high efficiency, no noise, easy installation and use, strong load-bearing capacity, fast rolling speed and reliable product quality. The profile bending machine is an ideal processing equipment for machinery manufacturing, petrochemical, shipbuilding, steel structure construction and other industries.
