防护罩的落料拉深冲孔复合模具设计【凸缘四孔圆筒形件冲压模】 摘要 防护罩——落料拉深冲孔复合模设计。通过分析制件的工艺性可确定制件的成形加工需要二副模具完成。即一套复合模和单工序拉深模。复合模是指冲床在一次行程中，完成落料、冲孔等多个工序的一种模具结构。相对其他冷冲压模具结构而言，它具有以下一些优点：①工件同轴度较好，表面平直，尺寸精度较高；②生产效率高，受条料外形尺寸的精度限制较校但需考虑的问题是：模具零部件加工制造比较困难，成本较高，并且凸凹模容易受到最小壁厚的限制。 单工序弯曲模的通用性能好，且制造简单。容易保证制件精度。 该制件形状较简单、对称。材料为优质08钢。工艺性好。 关键词：复合模工艺性能凸凹模模具制造 Abstract summary: Shield-bla
