When stamping different parts, or the punching machine fails or is damaged, the top die 7 may need to be replaced. It is only necessary to use a wrench to unscrew the nut 474 and pull out the bolt 473 to align the upper fixing plate 471 with the lower fixing plate The fixed plate 472 is separated, and the stamping equipment is removed from the crankshaft 3 for replacement. After the replacement is completed, it is only necessary to reset the fixed plate and tighten the bolts 473 and the nuts 474 before the stamping work can be carried out. When the top die 7 is replaced, the bottom die 6 may also need to be replaced. When replacing the bottom die 6, it is only necessary to loosen the fixing screw 510 and pry the handle 55.
