What is the problem with the angle iron punching machine cutting continuously?

Below is an answer to the question of the continuous cutting of angle iron punching machine:

1. Abnormal deep time system: causing inaccurate timing or unstable power supply to the solenoid valve; Need to replace the time-based relay.
2. Abnormal travel switch: sometimes it works, sometimes it doesn't work; Need to replace the travel switch.
3. Loose electrical components such as relays: causing poor contact and resulting in the directional valve not being in place; Need to tighten the connecting wire end.
4. Oil pump wear: leading to insufficient oil supply; The oil pump needs to be replaced.
5. Internal leakage of oil cylinder: causing pressure relief; The oil cylinder seal needs to be replaced.
6. The hydraulic oil is too dirty and the oil inlet filter is blocked, resulting in insufficient oil supply; Need to clean or replace the filter element.
7. Electromagnetic valve core jamming and blockage: causing insufficient supply to the oil cylinder; Need to clean the solenoid valve core
   The above is the answer to the question of what the angle iron punching machine is constantly cutting. I hope it is helpful.
