How to reduce springback of precision stamping parts

Netizens asked: How to reduce springback when applying bending force to precision stamping parts? 　　Metal stamping manufacturer answered: The factors that affect springback are: part material, plate thickness, punching force, die size and star shape. Because of the existence of these factors, if we comprehensively consider the nature of the speed of sound and the rebound, it is easy to find the cause of the rebound phenomenon, and then stop it. The root cause of springback is that after the material is bent, the bending part is subjected to uneven stress. If this part of the uneven stress is changed to a uniform stress, that is, the entire section is made of compressive stress or tensile stress, the amount of springback can be reduced. However, some parts have special requirements for deformation, such as not suitable for indentation, which must take a considerable plan in the design and process of precision stamping parts.
