Main points of maintenance and maintenance of metal stamping dies

In the metal stamping production, the daily maintenance of the mold is crucial, which affects the performance and service life of the mold. The maintenance of metal stamping processing molds requires attention to the following:

1. The mold must be sharpened after prolonged use. After grinding, the edge surface must be demagnetized, and it must not be magnetic, otherwise it will be prone to blockage.

2. Springs and other elastic parts are most susceptible to damage during use, and usually break and deform. The method adopted is to replace it. During the replacement process, you must pay attention to the specifications and models of the spring. The specifications and models of the spring are confirmed by the three items of color, outer diameter, and length. Only when the three items are the same can you replace them.

3. During the use of the die, the punch is prone to break, bend and nibble, and the punch sleeve is generally nibble. The damage of the punch and the sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include working part size, installation part size, length size and so on.

4. Fasten the parts and check whether the fastened parts are loose or damaged. The method is to find parts with the same specifications for replacement.

5. Pressing parts such as pressing plate, excellent adhesive, etc., and unloading parts such as stripping plate, pneumatic ejector, etc. During maintenance, check the relationship between parts and whether there is damage, repair the damaged parts, check the pneumatic ejector for leaks, and take measures for specific situations. Replace if the trachea is damaged.
