The cause of punch stamping mold damage in the process of: 1, check the stamping mould manufacturing materials whether appropriate, the corresponding heat buried technology is reasonable. In general, the influence of heat treatment process of stamping die materials is very large. If the stamping die quenching temperature is too high, quenching method and the time is not reasonable, and times and tempering temperature, improper selection between elbow bend pipe can lead to damage after mold in stamping production. Blanking hole size or inadequate depth design, easy to make slot blocking, blanking plate damage. Overlapping rushed, damage parts. Leads to the punch fall or broken. 2, stamping die, when using component location, direction of installation errors or bolts. Low working height adjustment, guide pillar insufficient lubrication. Abnormalities of the feeding device is faulty, press, causes the damage of stamping die. If there is a foreign body into the stamping moulds, overlapping parts, such as waste block is not handled in time, to continue processing production, it is easy to damage the mould of blanking plate, punch, the template and guide pin. 3, mold is not flexible, card mode. Stamping processing, mold comer can lead to mold damage, should immediately stop production. The cause of card molds are: die leads to bad, there is foreign body between tilt or template, the template can't appressed wait for a reason. This article reprinted self-propelled cutting machine
