摘　　要：分析了防护罩的结构和冲压工艺性,确定了冲压成形工艺方案,设计了1套落料拉深冲孔复合模,并对冲压成形的结构特点、工作原理和设计要点进行了介绍。实际生产表明,该模具结构合理,工作稳定,安装、调试、维修方便,生产效率高,产品精度高。The structure and punching process of shield were analyzed. The process program of punching was determined. A compound incision and extend punch die was designed according to the deterministic process program. The structure feature, working principle and design points of the compound incision and extend punch die were introduced. The practical production showed that the structure of the die is rational. The die can be operated stably, the products produced by the die had good quality.
