PAGE 毕业设计说明书(论文) 题 目： 弹簧卡多工位级进模设计 毕业设计说明书（论文）中文摘要 本文介绍了一种利用侧刃初定位、导正销精定位的多工位级进模。在分析弹簧卡零件冲压工艺的基础上,详细对比了零件的几种排样方案和冲切刃口的设计以及模具总体结构设计和主要零部件的设计。列举了零件的毛坯进行展开、冲压工艺的计算以及凸模强度的校核等过程，最终确定了本模具设计方案；本文所介绍的级进模共有12个工位，其成形的工序主要包括落料、冲孔、弯曲等；为了保证模具在工作时不发生干涉，在设计时应予以综合考虑；在文章的最后简单的介绍了级进模材料的选用及热处理并且详细列出了压力中心的计算过程。 关键词 弹簧卡 级进模 排样 模具设计 Title Design of multi-station progressive die for spring clinch Abstract A progressive die that is guided by pitch punch roughly and by the pilot pin exactly was designed. Based on the analysis of stamping process of typical spring clinch, compared in detail some kinds of stock layout and the design of cutting edge and the overall structure of the die and the design of the main parts of the die.Listed part the blank expand, the calculation of stamping process and check the strength of such punch process, Finalized the design of the mold. The progressive die had Twelve stations . The forming process contained blanking , Punching , bending and so on; In order to ensure nonintervention of the die in working , the forming process must be considered synthetically. Finally, the selection and heat treatment of die material and the computational process of pressure center were discussed in detail.
