Bending Machine Valve System

The bending machine valve group is one of the key hydraulic system components in the CNC bending machine. It is mainly used to control the flow direction, flow rate, pressure, etc. of the hydraulic oil to ensure accurate control and effective operation of the bending machine during the working process. It cooperates with a series of solenoid valves, control valves and regulating valves to realize the movement and positioning of the upper and lower molds of the bending machine, thereby realizing the bending of the plate.

Main Functions and Effects
Control the hydraulic flow direction: The bending machine valve group controls the flow direction of the hydraulic oil through the reversing valve, and then adjusts the lifting and lowering, forward and backward movement of the upper and lower molds to ensure that the machine tool can be accurately executed in different process steps.
Adjust pressure and flow: The oil pressure and flow in the hydraulic system are controlled by the pressure regulating valve and the flow regulating valve to ensure the stability of the bending force and speed and improve the processing quality.
Realize control: The high-precision control system of the bending machine valve group can ensure the accuracy of mold movement and avoid working errors caused by improper control.
Protection system: Through components such as safety valves, the bending machine valve group can avoid excessive pressure in the hydraulic system, play a protective role, and avoid equipment damage.

Main Components
Solenoid valve: used to switch the direction of hydraulic oil and control the flow of oil between different working units.
Pressure control valve: used to adjust the working pressure of the hydraulic system to ensure stable operation of the system.
Flow control valve: adjust the flow of hydraulic oil, control the system speed, and ensure uniformity during the bending process.
Directional valve: used to switch the flow direction of hydraulic oil and control the action sequence of each cylinder.
Safety valve: used to automatically release pressure under overpressure or abnormal conditions to protect the hydraulic system from damage.
Stop valve: used to stop hydraulic flow to ensure that the hydraulic system will not continue to work after the machine stops.

Application Scenarios
Bending machine valve groups are widely used in CNC bending machines, hydraulic bending machines, mechanical bending machines and other equipment. They are suitable for bending processing of various metal sheets, especially those requiring high-precision and high-force bending, such as:
Sheet metal processing

Maintenance and Care
As an important component in the hydraulic system, the valve group of the bending machine needs regular maintenance and inspection. Common maintenance measures include:
Regularly check the quality and oil level of the hydraulic oil to keep the system clean and prevent impurities from entering the valve group.
Regularly clean the reversing valve, regulating valve, etc. to ensure smooth movement of the valve core.
Check the sealing of the valve group to avoid leakage.
Replace aging or damaged parts in time to ensure continuous and stable operation of the system.
