某大梁成型工艺控制研究

Forming technology control research of a car beam

通过某汽车后大梁零件的成型分析,详细讲解了高强度钢板回弹的影响因素。如何在成型过程中尽可能减小回弹的影响,包括模具结构、产品的几何特征、辅助机构等相关因素都需要考虑,通过大梁的成型过程总结出了高强度钢板梁类工件回弹分析及控制的一般常用方法。

Aided by a car beam forming analysis, this paper detailed the factors of spring back of high strength steel. How to make the spring back as little as possible, the die structure, product geometry features, ere, were discussed on the lines. A general method to decrease the spring back has been laid out considering those factors through the process of a rear beam.
