Long-term use will reduce the precision of precision metal stamping dies, and various parts of precision metal stamping dies will have problems, so it is necessary to make proper maintenance. The precision parts processing factory will tell you about the common bad stamping phenomenon in production. The reasons and countermeasures are analyzed as follows.
Precision metal stamping dies require maintenance to extend service life. In the maintenance process of precision metal stamping dies, the following should be noted:
1: Precision metal stamping die must be sharpened after long-term use. After grinding, the cutting edge surface must be demagnetized, and it must not be magnetic, otherwise it will easily block the material.
2: Springs and other elastic parts are most vulnerable to damage during use, and usually breakage and deformation occur. The method adopted is to replace. In the process of replacement, we must pay attention to the specifications and models of the spring. The specifications and models of the spring are confirmed by the color, outer diameter and length. Only when all three items are the same can be replaced.
3: During the use of precision metal stamping die, the punch is prone to breakage, bending and smashing. The punching sleeve is generally smashed. Damage to the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the working part size, the mounting part size, and the length size.
4: Fasten the parts and check whether the fastening parts are loose or damaged. The method is to find the parts with the same specifications for replacement.
5: Pressing parts such as pressure plate, superior glue, etc., unloading parts such as stripping plate, pneumatic top material, etc. During maintenance, check the accessories of each part and whether there is any damage, repair the damaged part, check the pneumatic top material for air leakage, and take measures for the specific situation. Replace if the air tube is damaged.
6: Regular oiling to maintain bright lubrication and rust prevention.
