Automatic Bending Machine Valve Group

The valve group of the automatic bending machine is the core component of the hydraulic control system specially designed for the automatic hydraulic bending machine. It is mainly used to control the flow, pressure and direction of the hydraulic oil to adjust the movement of the upper and lower dies of the bending machine. Through the intelligent control of the valve group, the automatic bending machine can achieve fast bending operations, thereby improving processing accuracy, production efficiency and the automation level of the equipment.

Main Components
The components of the automatic bending machine valve group generally include the following categories:
Solenoid valve:
Used for automatic control, receiving signals from the CNC system, adjusting the flow direction and flow of hydraulic oil, and realizing the control of the hydraulic system.
Pressure control valve:
Controls the pressure of the hydraulic system to ensure that the system does not exceed the set safety pressure range during operation to avoid overload.
Flow control valve:
Controls the flow of hydraulic oil, adjusts the working speed of the bending machine, and ensures a smooth transition between each bending step.
Directional valve:
Controls the flow direction of the hydraulic oil, determines the lifting direction of the upper or lower die, and then completes the bending action.
Safety valve:
Automatically releases pressure when the pressure of the hydraulic system is too high to prevent equipment damage.
Overflow valve:
When the oil pressure of the system exceeds the set value, the overflow valve will automatically open to release pressure to ensure the stable operation of the system.
Throttle valve:
Used to finely adjust the flow of hydraulic oil and control the speed and accuracy of the bending machine.

Working Principle
The automatic bending machine valve group controls the flow, pressure and flow direction of hydraulic oil by receiving signals from the CNC system to realize various actions of the bending machine. During operation, the hydraulic pump sends high-pressure hydraulic oil to the valve group, and the solenoid valve in the valve group adjusts the oil flow and pressure according to the instructions of the CNC system to drive the piston of the hydraulic cylinder to complete the bending action.
Oil flows into the system: the hydraulic pump delivers hydraulic oil to the valve group.
Solenoid valve adjustment: the solenoid valve adjusts the flow direction of the hydraulic oil according to the instructions of the CNC system, controls the oil to enter different hydraulic cylinders, and pushes the upper or lower mold up and down.
Pressure regulation: the pressure control valve ensures that the pressure of the system is stable in the appropriate range during operation to avoid overload or damage.
Safety protection: the safety valve and the overflow valve monitor the pressure of the system in real time to prevent system damage due to excessive pressure.
