Progressive die template design

The standard progressive die template includes: discharge plate, fixed plate, concave template, upper die seat, and lower die seat.　　 Among them, the discharge plate, the fixed plate, and the concave template are the key three templates, which are also indispensable for the progressive die.　　 The fixed plate plays the role of fixing the punch; the unloading plate mainly plays the three functions of unloading, guiding and pressing; the concave template can not only serve as the edge of the concave die, but also inlay the concave die insert on it. Four small guide posts are used to guide between the three templates. The four small guide posts are fixed on the fixed plate of the punch, and the discharge plate and the concave template are respectively inlaid with four small guide sleeves to precisely control the small guide posts and The matching accuracy between the small guide bushes is to ensure the movement accuracy of the punch. In the design of progressive die, one item is also very important, that is, the design gives way. Generally, all subsequent stations of bending or forming stations need to give way, and they must give way fully. Not only should static give way, but also Consider whether dynamics need to give way.
