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。

Abstract
summary: Shield-blanking tensile punching compound die stamping design.The craft that passes the analysis system piece can make sure to make the piece to take shape to process to need two molding tools to complete.Namely a set of compound mold and the singlework preface bent mold.The compound mold mean the punching machine is in a route of travel, completing to fall to anticipate, a kind of molding tool structure of severalwork prefaces of etc. of blunt bore.Opposite and other cold hurtle to press the molding tool structure but speeches, it has following some advantageses :The①work piece is together the stalk degree is better, the surface is straight and even, the size accuracy is higher; The② produces the efficiency high, be subjected to the anticipates the shape size of accuracy limit smaller.But need the problem of the consideration is :The molding toolzero partses process the manufacturing more difficulty, the cost is higher, and the convex and cave mold is subjected to the thick restrict of minimumwall easily.
The singlework preface curves the in general use function of the mold good, and the manufacturing is in brief.An accuracy of easy assurance system.
Should make a shape to compare simple, symmetry.The material is high-quality 08 steelses.Craft good.
Keyword: compound die craft function The convex and cave mold molding tool manufacturing
