摘要
回弹是高强钢板冲压成形中影响冲压件尺寸精度和形状精度的关键因素。针对采用DP600高强钢的北京奔驰某车型的横梁减震器后桥零件,开展了零件成形、切边、回弹的全工艺流程CAE仿真分析,获得了零件的回弹特征;针对宝钢材料的性能范围获得了回弹的波动范围,并通过模具补偿的方案进行回弹控制,试验测量结果表明其形状精度得到了明显改善。
Springback is a key factor that influences the dimension and shape precision of AHSS part during the stamping process.In order to study springback characteristics of DP600 AHSS cross member absorption rear part,FEM was used to analysis the forming,trimming and springback process of the part.And springback fluctuation range of the part was obtained.Then the die compensation method was put forward for the springback control.The experiment results show that the shape precision is improved effectively after using the springback control method.
