Precision punch industry more and more hot, but we can not ignore the maintenance of punch and stamping die. As people must rest, precision stamping dies must be maintained and maintained. Today, I'd like to talk about how to maintain the stamping dies of precision presses.

In the design process of precision punch, the die strength is better, the die structure and gap should be effective, and the surface of stamping die should be polished and cut carefully to improve the die life. In the stamping process of precision punch, it is necessary to avoid the defects such as cracks, knife lines and collision scars left on the surface of the parts in the work of the die. The existence of such defect traces will cause stress, become the root of cracking, and cause damage to the stamping die.

According to the tonnage size of the precision punch, the die suitable for punching shear force should be used, and the surface condition of the parts should be avoided during the process of stamping parts. Check the clearance of the left and right side of the die before and after the die is installed, and check the left and right side of the die to ensure that the die surface is lubricated before and after installation.

In the stamping production of precision punch, the relative position and edge of the die should be lubricated or pressed oil on time after long-term application. The iron powder material in the cutting edge of stamping work should not be too much stagnant. It is necessary to solve the problem of retention immediately and remove the waste materials on time. After the production is completed, the mold should be completely cleaned and inspected to ensure the cleanliness of the mold.

After a long period of application, the edge of stamping die is ground and demagnetized to avoid blocking material caused by magnetism. Check whether the forbidden parts are loose and adopt recovery measures immediately.

The tips of the maintenance and maintenance of the stamping die of the precision punch are very simple. If we pay attention to the above reminder, we will not only improve the quality and characteristics of the stamping die, but also make the service life of the die change for a long time.
