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. through the process of the programme identified by blanking, drawing, punching complex processes through punching power, pushing pieces of unloading and so the calculation to determine the pressure Type of equipment and die, the die-back of used planes, feeding methods from right to left.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 conveniently; 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 struc
