摘　　要：在对杠杆块进行冲压工艺分析的基础上,根据冲压件材料以及生产批量进行排样设计,制定模具结构方案,给出了关键部件的设计.采用两组斜楔机构设计弯曲部分,给出模具的加工工艺和压力中心计算结果,并对关键部件进行应力应变分析.分析结果和生产验证均表明,模具结构合理,制件成型性能较好.Based on the analysis of the stamping process of lever blocks and the material and production batch, a layout die structure and the key parts have been designed. Two groups of inclined wedges were adopted in designing the bending parts. The processing technology of the mould and the result pressure center were also given. At last, the stress and strain of the key parts were analyzed. Both the analysis of the results and the production test showed that the die structure was reasonable, and the stamping shape performances were good.
