冲床作业,它的工作效率的提高,大部决定于冲模的改进。咱们都知道,在冲床上工作,冲一次至多只能完成一道工序;这样不但工作效率低,而且也不能充分发挥机床的潜力。因此要提高劳动生产率,就不能不在冲模上想办法。这里介绍几种简单的复合冲模给大家参考。这种冲模,可以把两道以上的工序,合并在一起进行,简化了操作手续,因而大大的提高了的工作效率。一、冲压小于90°弯铁的冲模这种冲模一般都分为两种,一种 Punch operation, its work efficiency, most decided to improve the die. We all know that working on a punch press can only accomplish one process at a time; it is not only inefficient, but it also does not give full play to the potential of a machine tool. Therefore, to improve labor productivity, we can not but think of ways on the die. Here are several simple composite die for your reference. This die, you can put more than two processes, merging together, simplifying the operating procedures, thus greatly improving the work efficiency. A stamping less than 90 ° bending iron die This die are generally divided into two kinds, one
