回弹是汽车覆盖件冲压成形时产生的主要质量缺陷之一,直接影响到覆盖件产品的尺寸精度和最终形状。以某汽车覆盖件为例,利用板料成形仿真软件Dynaform实现了零件的冲压成形和回弹模拟,重点预测了实际板料冲压成形后可能出现的回弹量,并优化模具型面来控制回弹。通过将仿真结果与实际生产合格零件作对比,验证了优化方案的合理性和仿真模拟的准确性,对汽车覆盖件模具生产制造具有重要的指导意义。

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 Dynaform software,emphasizing on the possibly spring-back quantity forecasted and the die surface was optimized to control spring-back.The reasonability of optimization scheme and veracity of simulation were proved by comparing the simulation result with the eligible part obtained.And it provides a significant guidance to the manufacture of the automotive panel dies.
