Two ways to control the rebound of precision shrapnel

What should I do if the precision shrapnel springs back during the bending process? Precision has two methods to control the springback of stamping parts, for your reference. There are two methods to control the rebound of precision shrapnel. One is the over-compensation method, and the other is the process control method. According to the trend of springback, making a compensation angle consistent with the expected springback in the mold, or controlling the excessive punching of the punch, is the so-called compensation method. This is a widely used method to control the rebound of precision shrapnel. However, when there are complex-shaped curved products and high-precision requirements, the precision control of springback is limited because it is difficult to accurately estimate the amount of springback. The second way to change the stress state of the sheet, the process control method is used to control springback. Usually this process includes: stamping, stretch bending, and thermal bending. During the stamping process, the additional stress in the thickness direction of the plate changes the stress distribution in the bending deformation area. By applying a tangential tensile deformation and reducing the bending moment at the bending of the precision shrapnel, the rebound of the sheet can be controlled.
