The progressive die could complete twenty processes that include punching, bending, and so on. The high-speed punching machine in adoption proceeds to press, the automatic feeding system fixed position imprecisely, the edge knife and the leading pin fixed position accurately. It detailly introduced the design and manufacture of the punch, the die, the stripping device, the guiding system, and slippery piece. And it expatiated the work process of the die, the coordination of each figuration’s motion, and the assemble cleft of the punch and die. Also it established th...
