The research of springback compensation design method based on reverse modeling

To solve the springback problem of automotive covering parts, a springback compensation design method of Stamping die based on reverse modeling is researched. By the Alignment module in Poly Works software, springback analysis is quickly implemented. Then, According to the results of springback analysis, the springback compensation design method which used the smooth displacement adjustment theory is established. At last, Set an inner plate of wheel housing as example, the methods has been applied in springback analysis of the part and springback compensation design of the die-face, which effectively reduces the times of compensation in try pressing stage and improves productivity.
