针对双撑座板件的冲裁、弯曲生产工艺,设计了特殊级进模总体结构,以及排样方案的选择和关键部件的设计。解决了送料中弯曲方向不一致问题;采用分步冲裁,解决了复杂型孔冲制问题;采用将弯曲线移开一定距离及增加工艺槽方法,解决了弯曲后产生裂痕问题。实践证明:模具结构灵活可靠,加工质量好,生产效率高。

The productive technology of double supporting plate seated parts including blanking and bending was analyzed and the whole structure of the special progressive die was introduced.The selective validity of its layout arrrangement was proved and the design method of key parts was given.The inconsistent feeding problem in bending direction was solved.The punching of complex hole was figured out by substep punch.The problem of yielding crack after bending was settled down by which bending line was removed a certain distance and technological trough was increased.Through practice,it is proved that the die structure is detailed,simple and reliable.The processing quality is good and productivity is high.It has an important reference value to the progressive die design of the similar parts.
