Factors affecting springback in sheet metal processing

In lapidibus metallis processionis in Shenyang, factores 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. Quantum maior est perspectus tortuus, maior est terra deformation is, ita et maior est rebound.

(4) The impact of twists and turns. Lingua libera maior est quam mola bendere, et latitudinem et densitatem metallorum impleverunt super reboundum.

In general, there are many factors that affect rebound. A result of the impact of rebound, the bent edge cannot be tightly attached to the working part of the mold, but the corner edge is stretched out, 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.
