Factors affecting springback in sheet metal processing

In Sheet Metal Processing in Shenyang, the factors that affect rebound include:

(1) The influence of material mechanical properties. Generally speaking, the higher the yield stress of the material, the greater the rebound.

(2) The influence of deformation degree and curvature radius.

(3) The influence of convoluted viewpoints. The larger the tortuous viewpoint, the larger the deformation area, so the rebound is also greater.

(4) The impact of twists and turns. Free bending has a greater rebound than bending with a mold, and the width and thickness of the sheet metal have an impact on rebound.

In general, there are many factors that affect rebound. Due to the impact of rebound, the bent edge cannot be tightly attached to the working part of the mold, but the corner edge is stretched outward, resulting in a slight increase in the bending point. Therefore, the bending point of the sheet metal on the mold will not be the same as the working point of the mold, but slightly larger than the working point of the mold.
