Introduction to the main points of maintenance of metal stamping dies
In the production of metal stamping, the daily maintenance of the mold is very important, which affects the performance and service life of the mold. For the maintenance of metal stamping dies, you need to pay attention to the following items:
1. After the mold is used for a long time, the cutting edge must be sharpened, and the cutting edge surface must be demagnetized after grinding.
2. Springs and other elastic parts are most easily damaged during use, and they usually appear to be broken and deformed. The method adopted is to replace. In the process of replacement, you must pay attention to the specification and model of the spring. The specification and model of the spring are confirmed by the three items of color, outer diameter and length. Only when the three items are the same can they be replaced.
3. The punch is prone to breaking, bending and gnawing during the use of the mold, and the punch sleeve is generally gnawed. The damage of the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, and the length dimension.
4. Fastening parts, check whether the fastening parts are loose or damaged. The method adopted is to find the parts of the same specification for replacement.
5. Material pressure parts such as material pressure plate, Uniglue, etc., discharge parts such as stripper plate, pneumatic ejector, etc. During maintenance, check the relationship between the parts of each part and whether there is damage, repair the damaged part, check whether there is air leakage in the pneumatic jacking, and take measures for the specific situation. If the trachea is damaged, replace it.
