The knowledge of maintenance and upkeep of metal stamping molds mainly includes the following:

1. After long-term use, the cutting edge of the mold must be polished, and the surface of the polished cutting edge must be demagnetized and non-magnetic, otherwise it is easy to cause material blockage.

2. Elastic components such as springs are more prone to damage during use, often resulting in breakage and deformation. The method of doing this is replacement. During the replacement process, it is important to pay attention to the specifications and model of the spring. The specifications and model of the spring are determined by color, outer diameter, and length. Only when all three items are the same can it be replaced.

3. During the use of molds, the punch is prone to breakage, bending, and gnawing, and the punching sleeve is generally gnawed. The damage to the punch and punch sleeve is generally replaced with parts of the same specifications. The parameters of the punch mainly include the dimensions of the working parts, installation parts, length dimensions, etc.

4. Tighten the parts and check for looseness or damage. The method used is to replace the parts with the same specifications.

5. Pressure parts such as pressure plates and U-glue, as well as unloading components such as demoulding plates and pneumatic top shafts. When repairing, check the relationship between the parts and whether there is any damage, correct the damaged parts, check for air leakage in the pneumatic top material, and take measures for specific situations. If the trachea is damaged, please replace it.
