Maintenance of metal molds

1: After long-term use of the abrasive tool, the edge of the knife must be sharpened. After grinding, the surface of the stainless steel standard part of the precision stamping part of the knife must be demagnetized. It cannot contain magnetism, otherwise it is easy to cause material blockage.

2: The ductile parts such as spring yellow are easily damaged in the whole process of application, and generally appear cracked and deformed. The method used is to dismantle and replace. During the whole process of disassembly and replacement, you must pay attention to the specifications, models and specifications of the bullets. The specifications and models of the bullets are determined according to the three items of color tone, diameter and length. There are only three items. Can be replaced under the same conditions.

3: During the whole process of abrasive application, the punching needle is prone to breakage, bending and gnawing, and the punching sleeve is generally gnawed. The damage of the punching needle and punching sleeve is generally carried out with the same specifications and models for replacement. The main parameters of the mechanical parts of the punching needle are some specifications in the work, some specifications for installation, and length specifications.

4: Tighten the parts, and check whether the tightened parts are loose or damaged. The method used is to find parts of the same specification and plastic hardware for replacement.
