How to maintain the precision high-speed punch mold?

The service life of the precision high speed punching die depends on the reasonable structure of the die, the high manufacturing precision, the good heat treatment effect, the correct selection of the punching machine, and the die installation accuracy of the punching machine. The following points should not be ignored.

1. Dirt cleaning

Before the high speed punching die is installed, a strict inspection should be carried out to remove dirt and check whether the die guide bush and die are well lubricated.

2. Die base

Regularly check the rotating column and die mounting seat of the high-speed punch to ensure that the complementary accuracy of the upper and lower turntables is consistent.

3. Mold positioning

Install the convex and concave dies on the turntable according to the mold installation procedure to ensure that the direction of the convex and concave dies is consistent, especially the molds with direction requirements (non-circular and square) should pay attention to prevent errors and reverse installation.

4. The softness of the installation tool

Stamping personnel should use operating tools made of softer metals (such as copper, aluminum, etc.) to prevent knocking or smashing the mold during installation.

5. Inspection after mold installation

After the mold is installed, check whether the fastening screws of the mold mounting seat are locked.

6. Timely sharpening

After the punching die and die edge are worn, they should be stopped and sharpened in time, otherwise the wear degree of the die edge will be rapidly expanded, the die wear will be accelerated, and the quality and life of the stamping parts will be reduced.

7. Spring replacement

In order to ensure the service life of the mold, the spring of the mold should also be replaced regularly to prevent the spring from affecting the use of the mold due to fatigue damage.

8. Anti-rust treatment

After the mold is used, it should be put back to the designated position in time, and oiled to prevent rust.

9. Mold transportation

In the process of transportation, the mold should be handled with care, do not throw or touch, so as not to damage the edges and guide plates of the mold;

10. Mold backup

For the commonly used molds used in mass production, there should be backups for rotation production to ensure production needs.
