How To Reduce The Mold Wear Of The Punch?

Mold Wear Of The Punch

Mold Wear Of The Punch

The wear of CNC punch dies is mainly reflected in the following points:

1. The mold alignment of punch equipment designed and processed before leaving the factory is poor.

The poor alignment of the die position hole will cause collision and friction during the use of the die.

At present, the die position alignment accuracy of the so-called first-line CNC punch manufacturers in China can only be controlled at 2 wires, and only a few of them can hit the level of 1 wire.

The poor alignment of the die position will directly damage the die.

2. The material performance of punch die is poor.

I won’t say much about this. Because the molds run at high speed in the process of use, the molds with poor materials, deformation, uneven heating and so on all affect the loss.

3. Insufficient lubrication.

Many friends will say, how to lubricate the mold?

In the process of high-speed use, the die is in contact with the die base or guide hole for a long time.

During the up and down operation of the die, the machine tool will inevitably have some inclined vibration.

If there is no lubrication, the die will rub with the guide hole or die base.

Do you say the die will be damaged?

4. The environment is too dirty.

If your punch is located in a dusty place, the interior of your die will be full of dust in a few days. The die is stuck and does not rebound from time to time, and even it is very dangerous to break the punch.

5. The processed workpiece is too thick or too thin.

Originally, the stamping thickness of the punch designed may be 6mm at most.

You have to let it work in an environment above 6mm for a long time.

It’s strange that the die is not damaged.

The applicable thickness of standard punch is between 0.8-6.

6. The processing speed is too fast.

I know this. You blindly emphasize efficiency and run at high speed at full load all day. The mold of NC punch can’t carry it.

7. The optimization of processing procedure is not in place.

When many users use the punch, the die breaks.

This usually happens during edge processing.

When the die rushes down, only half or less of the cutting surface of the die contacts the workpiece, and the force is uneven.

It is not surprising that the die breaks.

Conclusion

In short, there are many factors of die loss.

Paying attention to maintenance and rational use is the correct way to reduce loss.

You can make corresponding improvements for some of the above reasons, which should avoid or reduce some damage.
