1、 Insufficient pressure of pneumatic punch press
During the use of pneumatic punching machines, there may be insufficient pressure, resulting in poor punching quality and even inability to complete the punching task. There are two main reasons for insufficient pressure, one is blocked gas path, and the other is insufficient gas source.
resolvent:
1. Check if the air circuit is blocked, clean or replace the blocking parts. Check the air circuit components such as filters, sleeves, pressure reducing valves, and tees of the pneumatic punch press, clean or replace any blockages to restore normal air flow.
2. Check if the gas source is sufficient. If the gas source is insufficient, the gas source can be increased by increasing the gas source capacity or increasing the outlet pressure of the compressor.
2、 Pneumatic punch stuck
Pneumatic punching machines may get stuck during use, causing them to malfunction. The reason for jamming may be that the punch is stuck on the mold, or it may be that the workpiece is too hard to complete the punching task.
resolvent:
1. Check if the punch is stuck on the mold. If so, first unlock the mold locking mechanism, then gently push the punch to loosen it, and finally re lock it to allow the pneumatic punch to resume normal operation.
2. Check if the hardness of the workpiece is too high. If the workpiece is too hard, the punching task can be completed by reducing the groove depth of the punch.
3、 Wear of pneumatic punch head
During the use of pneumatic punching machines, the punch may be worn or ground flat, greatly reducing the service life of the punch. The reason for punch wear may be due to high material hardness or unreasonable punch design.
resolvent:
1. Replace the punch with a harder material. Replacing the material with a harder punch can increase the service life of the punch. When choosing a punch, factors such as the diameter of the punch, the material of the workpiece, and the applicable punch model should be considered.
2. Replace the appropriate punch design. Replacing the appropriate punch design can reduce the risk of punch wear and improve the service life of the punch. When choosing a punch, factors such as its own structural characteristics, material hardness, and accuracy of the guiding component should be considered.
Overall, the focus of punch press troubleshooting is to quickly eliminate faults, improve production efficiency, and ensure smooth production. The above faults and troubleshooting methods are for reference only. Specific maintenance methods need to be carried out according to the specific situation of the punching machine fault.
