How to improve the service life of the mold in practice?
In practice, the method of increasing the service life of the mold:
1. Keep the position of the mold parts stable
When the mold is working, all the parts on the mold are required to maintain a stable design position. The mold processing gap includes uniform matching of punching, bending, forming and the like, and is an important aspect of controlling the relative position.
2. Material control in stamping
During the entire stamping process, how to ensure the position and support of the material to be stamped should consider the stress and strain of the material, as well as the constraints of the material.
3. Vibration control during mold operation
In order to extend the life of the mold, if the effective part of the punch is intentionally lengthened, measures should be taken to prevent the skew or twist caused by the vibration of the punch.
4. Waste control of parts
The increase in scrap is due to the excessive clearance. The tensile force acting on the material during punching makes the stamping part smaller than the die hole, and the scraping is caused by the vacuum suction caused by the bottom surface of the punch and the scrap. .
5, mold load control
It is required that the load center of the mold and the pressure center of the punch are substantially identical in the front, rear, left and right directions.
In short, if the above five aspects are fully considered in the design of the mold, the service life of the mold can be greatly improved, the maintenance cost of the mold can be reduced, and the economic burden of the enterprise can be reduced.
