河南机电高等专科学校毕业设计说明书支架拐件-落料冲孔复合模摘 要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。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：工件同轴度较好，表面平直，尺寸精度较高； 生产效率高，受条料外形尺寸的精度限制较小。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。 该制件形状较简单、对称。材料为优质05钢。工艺性好，容易保证制件精度。关键词：复合模、工艺性能、凸凹模、模具制造支架拐件落料冲孔复合模AbstractBy analyzing the properties of the workpiece, it can be formed trough a compound blank and pierce dies. That is a compound mould. Compound mould is punch complete the blanking and punching at one stroke of the press. Compared to other cold stamping die structure, it has the following advantages : First,coaxial better workpiece surface is straight, high dimensional accuracy; Second, high production efficiency, by the dimensions of the material accuracy less restricted. But questiones to be considered are the difficulties in processing and manufacturing and high costs, and punch and die are easily constrained by the minimum wall thickness. The component is relatively simple shape, symmetry. 05 high-quality materials for steel. Technology is good.Easier to ensure that component accuracy.Keywords : Compound mold 、craft
