What is the cause of the pressure instability in the cutting machine?

Cutting machines use 10% of the pressure instability within 5 years, and even new machines appear unstable.
     First of all, let's first understand what is the pressure instability of the cutting machine: In the case of no die change, no material change, and normal operation, the occurrence of a certain knife or continuous knife cutting and cutting too deep is unstable.

The following situations are not unstable:
1, Cutting depths in the cutting area are different.
2, cutting the left and right positions within the cutting field is not the same depth.
3, After changing the tool changer, the material can be cut continuously or cut too deep.
4, on the bench can sometimes get up and sometimes can not get up, and so on!

The slight pressure instability of the cutting machine will cause the die and the backing plate to be scrapped in advance, wasting time and money, and there is a safety hazard; the more serious pressure instability is very dangerous during operation, damage the die, damage the backing plate, and sometimes the knife The die is pressed against the backing plate and cannot even be pulled back. The cracked backing plate will splash to the operators and cause a series of dangers such as personal injury.

So what causes the machine pressure to be unstable?
1, electrical reasons. Electrically induced pressure instability is generally caused by poor line contact, poor relay quality or damage to the relay, damage to the end point of the trim, trip damage to the switch, and poor quality or damage to the time relay.
2, hydraulic system. Leakage in the oil circuit, damage to the solenoid valve or poor reflection, and unstable pump displacement. Note: The case shows that all parts of the electrical components have been replaced but the fault remains. At this point you need to install a voltage regulator system.
3, The mechanical instability caused by pressure instability has not been discovered before. The possibility of mechanical instability caused by pressure is almost established.
