摘　　要：应用CAE分析技术模拟板料成形全过程,预测板料在成形过程中出现的起皱、变形不良等缺陷,修改冲压工艺方案后通过仿真计算进行验证,验证结果表明:在压料面增设拉延筋后,有效地控制了起皱的发生,且零件各部分变形充分,达到加工硬化及提高表面质量目的;利用Pro-E软件、采用自上而下设计的方法进行模具体的结构设计,介绍了总体设计思路、工作零件的详细设计及模具工作原理。The whole process of sheet metal forming was simulated using CAD/CAE. The defects of wrinkle and insuf- ficient deformation of sheet metal when forming were predicted. And then, the simulation calculation was done after modifying the stamping process scheme. The validation results show that the wrinkle is controlled sifter adding the drawbead in the pressure surface, and the parts are fully deformed, which realizes the work-hardening and improves surface quality. The mold structure was designed using top-down design method by Pro-E, the general design ideas, detailed design of working parts and die working principle were introduced.
