摘　　要：介绍了一种端盖的模具设计方案。由假想冲压工步,到板料CAE分析验证,设计模具逐步实施。用Dynaform分析减薄率分布云图以及成形极限图,在不同压边力进行仿真模拟、防止材料起皱,拉裂等现象,逐步验证冲压工序以及成形状态。分析了批量生产条件下其冲压工艺过程及模具设计要点,通过对CAE仿真分析,找到了一条解决端盖深拉伸的开模途径。This paper introduces a kind of die design scheme for end cover. From imaginary stamping steps to CAE analysis and verification of sheet metal, the die design is gradually implemented. Dynaform is used to analyze the nephogram of thinning rate distribution and forming limit diagram, and simulation is carried out under different blank holder forces to prevent material wrinkling and cracking. Gradually verify the stamping process and forming status.The stamping process and the key points of die design under the condition of mass production are briefly analyzed. Through the CAE simulation analysis, a way to solve the deep drawing of the end cover is found.
