What Causes the Angle Steel Punch‑Shear Machine to Fail to Cut Through

Here is an explanation of why an angle steel punch‑shear machine cannot cut through materials:
1. Abnormal timer controller: Resulting in inaccurate timing or unstable power supply to the solenoid valve; replace the timer relay.
2. Malfunctioning limit switch: Intermittent operation; replace the limit switch.
3. Loose electrical components such as relays: Poor contact leads to incomplete valve spool movement of the directional valve; fasten the wiring terminals.
4. Worn oil pump: Insufficient oil supply; replace the oil pump.
5. Internal leakage of the oil cylinder: Pressure relief occurs; replace the oil cylinder oil seal.
6. Dirty hydraulic oil and clogged oil‑inlet filter element: Insufficient oil supply; clean or replace the filter element.
7. Sticking or unsmooth movement of solenoid valve spool: Insufficient oil supply to the oil cylinder; clean the solenoid valve spool.
