Analysis of springback cause about the profile bending machine
According to the requirement of the shape of the components, bending process is applied to make the plate or section steel into a qualitative shape by using the bending machine equipment and certain die and mould.
Processing method of BR180 Angle Roller can be divided into rolling and bending methods.
What factors affect the springback when the profile bending machine works?
1, 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 greater the value of the r/t.
3. The larger the deformation area, the greater the rebound.
4. Friction between the surface of the material and the surface of the die affects the stress state of the parts of the embryo. In most cases, the tensile stress in the bending zone will be increased, and the rebound is reduced.
