【Abstract】 According to process analysis of structure and dimensional tolerances of spacer,the forming difficulties of the part were proposed.The rigid die drawing method was determined through analysis of finite element simulation of deep drawing.Based on the finite element springback simulation and experiment,the theory-based surface of the deep drawing forming mold was corrected reasonably.Therefore,the problems of the dimensional accuracy of the part’s height and curved surface were solved.The reasonable blank holder force was proposed by analyzing the deep drawing forming effect in different blank holder force conditions.更多还原
