Research on Spring-Back Simulation and Die Surface Optimization of Automotive Panel Stamping Process

Abstract

The spring-back phenomenon in automotive panel forming is one of the main quality problems, which may affect the tolerance and final shape of panel products. The stamping and spring-back process simulation for the automotive panel were realized by using the Auto form software, emphasizing on the possibly spring-back quantity forecasted and the die surface was optimized to control spring-back. The reasonability of optimization scheme was proved by comparing the simulation result with the actual part.
