题目： 分度盘零件冲孔落料复合模设计 摘 要Abstract:This design carries on blanking, the piercing progressive dies design.The article has briefly outlined the press die at present development condition and the tendency.It has carries on the detailed craft analysis and the craft plan determination to the product.According to general step which the press die designs, calculated and has designed on this set of mold main spare part, for example: The punch, the matrix, the punch plate, the backing strip, the matrix plate, stripper plate, stop pin, pilot pin and so on.The die sets uses the standard mould bases, has selected the appropriate press equipment.In the design has carries on the essential examination computation to the working elements and the press specification.In addition, this die employs the finger stop pin and the hook shape stop pin.The mold piercing and blanking punch are fixed with the different plates separately in order to coordinate the gap cenveniently; The piercing matrix and blanking matrix are fixed by the overall plate.Fell in the blanking punch is loaded by pilot pin, guarante the relative position of the hole and the contour , increase the processing precision.This structure may guarantee the die move reliably and the request of mass production.
