What problems should be paid attention to in the maintenance of metal stamping dies?

The service life of the metal stamping die can be extended only after maintenance. During the maintenance of the metal stamping die, the following items should be noted:
1. The edge of the mold must be grinded after a long time of use. After grinding, the edge surface must be demagnetized without magnetism, otherwise it is easy to block material.
2. The punch is easy to break, bend and chew during the use of the die, and the punch sleeve is generally chewed. The damaged punch and punch sleeve are generally replaced with parts of the same specification. The parameters of punch mainly include working part size, installation part size, length size, etc.
3. Springs and other elastic precision stamping parts are most vulnerable to damage during use, and usually break and deform. The method adopted is to replace the spring. Pay attention to the specification and model of the spring during the replacement process. The specification and model of the spring are determined by color, outer diameter and length, and can only be replaced if the three items are the same.
4. Pressed parts, such as press plate, Uniglue, etc., and unloading parts, such as stripper plate, pneumatic jacking, etc. During maintenance, check the relationship between parts and whether there is any damage, repair the damaged parts, check whether there is air leakage by pneumatic jacking, and take measures for specific conditions. Replace the air pipe if it is damaged.
5. Fasten the parts and check whether the fastening parts are loose or damaged. The method is to replace them with parts of the same specification.
