一模多件冲压复合模具设计

摘要

通过对变电器开关压圈、大垫圈和小垫圈零件的冲压工艺分析,优化了模具结构设计,在一次成形过程中,使得冲孔、落料、拉深3个工序复合,在1套模具中可生产出3种不同类型的零件.生产实践表明,模具结构合理,模具工作过程可靠且操作简便.3种不同类型零件的冲压复合设计,满足了现代工业生产高精度、低成本、高效率的要求.%Through the analysis of the stamping process of the switch,the large washer and the small washer workpiece,the die structure design is optimized.In the process of forming,the punching,blanking and drawing process are compounded in one set of die,which can produce 3 different types of workpieces.Production practice shows that the die structure is reasonable,the die work reliably and easy to operate.The stamping composite design of 3 different types of workpiece meet the high precision,low cost,high efficiency requirements of modern production.
