垫片落料冲孔复合模设计
摘要
冲压制品已在工业,农业,国防和日常生活中的方面得到广泛应用,特别是在机械业中则为突出。机械产品的外壳大部分是冲压制品,产品性能的提高要求高素质的冲压模具和冲压性能,成型工艺和制品的设计。
冲压制品的成型方法很多。其主要用于是冲孔,落料,弯曲,拉伸等。而冲压模,约占成型总数的60%以上。当然如利用电气控制,可实现半自动化或自动化作业。
冷冲冲裁模主要用于金属制品的成型,它是冲压制品生产中十分重要的工艺装置。冲压模的基本组成是:上下模座、下模垫板、下模固定板、凹模镶块、抬料钉、导料板、卸料板,导柱导套、卸料板弹钉、卸料板等。
冲裁模成型的广泛适用,正是我这个设计的根本出发点。
