1、 手机盖冲压工艺分析及模具设计摘要:本设计详细的论述了冲压模具的全过程。首先,对零件做整体的分析。包括:材料的使用、精度的要求、工序的要求以及成本的要求等。为了降低成本,对排样方式进行了合理的设计;其次,对零件整体进行工艺设计。通过工艺目的的设计、工序的顺序设计、压力机的选择等来实现所要达到的要求;再次,想要保证制件精度的要求,就要考虑模具刃口尺寸的计算。最后,根据计算出的模具刃口尺寸设计出相应的凸凹模,并且查找资料选择冷冲压模的标准零件,符合标准后,就把凸凹模与其它各零部件进行总体装配。手机盖是一个形状相对比较简单的盒形件,需要的工序有落料、拉深、切边、冲孔。经工艺计算和分析,确定了合理的冲
2、压工艺方案,提出用冲孔落料模及拉深切边两套模具完成该零件的生产,设计出的模具结构简单、制造容易。关键词:盒形件,模具设计,复合模,落料,拉深Mobile phone cover stamping process analysis and die designAbstract :This paper discusses in detail the whole process of stamping dies.
