It's widely known that the downward movement of a shearing machine is under pressure, whereas the downward movement of a bending machine is not, as the shearing machine's downward movement is achieved by pressure pushing the nitrogen cylinder down. The return stroke is pressure-free, while the bending machine operates the opposite way, with the downward movement powered by the weight of the slider. The return action requires pressure to be applied.

Common issues with shearing machines, such as burrs on the cut material or difficulty in cutting through, include:

There may be an issue with the blade material of the shear machine.

The blade gap was not adjusted properly.

Is the anti-slip board damaged?

The hydraulic valve of the shearing machine operates on the principle of the opposite functions of the分流 valve and the集流 valve, commonly used in combination with electromagnetic pressure regulating valves for long-distance control of the oil, gas, and water pipeline systems in hydropower stations. The分流集流 valve combines the functions of both分流 valves and集流 valves. The hydraulic valve of the shearing machine is an automated component operated by pressure oil, often used in oil circuits for clamping, control, and lubrication. As such, after the throttle orifice area is set, the hydraulic valve of the shearing machine is used to reduce and stabilize the oil pressure in a specific branch of the system, thereby achieving stable operation. The throttle valve maintains a constant pressure difference between the inlet and outlet of the throttle valve in response to changes in load pressure. Regardless of how the load pressure changes, it is controlled by the pressure oil of the pressure regulating valve.
