Abstract：

In order to solve the serious springback problem of high-strength flat stamping parts and the instability of springback and springback compensation during the simulation process, for a certain automotive battery box cover plate, through the full process springback analysis of the part, the factors that affected the instability of springback compensation and their influencing laws were explored, and after comparative analysis of five process plans, the optimal plan for controlling the springback of part was determined. Then,the stamping experiments verification shows that for high-strength flat stamping parts, if a blanking forming scheme is used, the springback cannot be controlled through the process optimization methods, and the springback is unstable. A slight change in the process causes a change in the springback trend. However, a drawing forming solution of drawing drawing-trimming and punching-flanging is adopted, the springback is stable and qualified. The research method and research ideas have guiding significance for the production of similar parts.
