The precision punch industry is getting hotter, but we cannot ignore the maintenance of the punch and the protection of the stamping die. Just like people need to rest, precision stamping dies also need maintenance and protection. Today, I will talk about how to protect the stamping dies of precision punching machines.
In the design process of precision punching machine, the strength of the mold should be good, the mold structure and clearance should be reasonable, and the surface of the stamping mold should be processed by grinding and grinding to improve the life of the mold. In the process of precision punching, it is necessary to prevent defects such as cracks, knife marks, and impact scars on the surface of the mold working parts. The existence of these defect marks will cause stress concentration, become the root cause of fracture, and cause damage to the stamping die. According to the tonnage of the precision punch, a mold with suitable punching shear force should be used, and the surface of the part should be prevented from grinding and burning during the processing of the stamping parts of the mold. Check and adjust the gap between the punching and cutting edges of the die and ensure the cleanliness of the upper and lower surfaces of the die before setting the die, and ensure the parallelism of the upper and lower mounting surfaces of the stamping die during stamping production. After installation, check the sliding lubrication of the die and other parts. In the production of precision punch presses, the corresponding parts and cutting edges of the mold should be regularly lubricated or stamped with lubrication oil after long-term use. The iron powder in the cutting edge of the stamping operation should not stay too much, and the remnants should be treated in time and the waste should be cleaned regularly. After the production is completed, the mold should be thoroughly cleaned and inspected to ensure the cleanliness of the mold. After the stamping die has been used for a long time, the cutting edge is ground and the cutting edge is demagnetized to prevent material blocking due to magnetism. Check whether the forbidden parts are loose, and take repair measures in time.
The secret of maintenance and protection of the stamping die of precision press is very simple. Just pay attention to the above tips, not only will improve the quality and performance of our stamping die, but also make the service life of the die longer.
