Introduction to the battery shell stamping spring prevention crumbs

Batteries shrapnel jump crumbs, refers to the precision hardware mold in high speed blanking, rushed into the die cutting edge within the scraps be punch out of the mold surface phenomenon. It exists to pick-up or terminal pressure bad, which affects the quality of battery shell, is the 'big fear of high-speed continuous cutting production. Batteries shrapnel stamping the main reason for the jump crumbs: precision hardware mold is in the process of high speed continuous cutting cutting oil, clearance is too large, the influence of such factors as formation between the punch and attle instantaneous partial vacuum, when the material is very thin, weight of slivers the blade to the sum of the friction force is less than punch and die on its adsorption capacity, in the process of punch up, scraps and adsorption on the surface of the punch, rise, forming a jump crumbs. There are many factors that can affect jump crumbs, too much when the blade wear punch, cutting oil consumption, the material is very thin and short punch into the cavity depth and so on, all can lead to jump. At this time, can reduce the battery shell blanking clearance, die, punch processing abnormity edge processing job-hopping, vacuum blower, number of blade, reducing or changing the method to control such as cutting oil battery shrapnel stamping jump method.
