Structure and principle of guide plate single stage blanking die
Figure is a simple guide plate blanking die. The guidance of the upper and lower dies is based on the clearance between guide plate 9 and punch 5, so called guide plate die.
Die’s working parts are punch 5 and cavity 13; positioning pars are guide plate 10 and fixed stop pin 16, trigger stop pin 20; guiding part is guide plate 9 (acts also as a fixed stripper plate); supporting parts are punch fixing plate 7, backing plate 6, upper die seat 3, die shank 1, die holder 15; In addition, there are fastening screws, pins etc. According to die layout, the position of the fixed stop pin of this die will not be able to position the first punching. For this purpose, the trigger stop pin 20 is used. Before first punching, trigger stop pin will be pressed by manual to limit the strip material. In the subsequent punching, the stop pin will begin to be used and trigger stop pin is ejected by the spring.
