High Pressure Bending Machine Valve Group

High-pressure bending machine valve group is designed for high-pressure hydraulic system and is specially used for hydraulic control system in high-pressure bending machine. It is responsible for accurately controlling the flow direction, pressure and flow of hydraulic oil to achieve safe operation of bending machine under high-pressure working conditions. Since high-pressure bending machine is usually used to process heavy or high-hardness metal sheets, the valve group needs to have the characteristics of withstanding high pressure, providing stable output and high-precision control.

Main Functions and Effects
High-pressure hydraulic control: The high-pressure bending machine valve group can work stably under high-pressure environment, accurately control the flow direction, flow and pressure of oil in the hydraulic system, so as to achieve accurate control of the movement of bending machine mold.
Bending force adjustment: Through the pressure control valve, the oil pressure in the system can be adjusted to control the bending force applied by the bending machine to ensure that metal sheets of different thicknesses and materials can be processed.
Safety protection: The high-pressure bending machine valve group is equipped with safety valves, overflow valves and other protection devices to prevent the system pressure from exceeding the safety range and protect the safe operation of hydraulic systems and equipment.
Work: Through the adjustment of the flow control valve, the hydraulic oil flow is accurately controlled, thereby improving the equipment operation speed and work efficiency, and avoiding processing errors caused by excessive flow or uneven flow.
Automation and remote control: Modern high-pressure bending machine valve groups can be integrated with CNC systems and PLC systems to achieve automatic control, further improving work accuracy and production efficiency.

Main Components
Electromagnetic reversing valve: responsible for switching the flow direction of hydraulic oil, controlling the movement sequence and accuracy of the upper and lower dies of the bending machine, and ensuring that each action can be completed accurately.
High-pressure safety valve: When the hydraulic system pressure exceeds the set value, it automatically opens to release excess pressure to prevent excessive oil pressure from damaging the hydraulic system or bending machine components.
Flow control valve: used to adjust the oil flow in the hydraulic system, thereby controlling the speed of the bending machine and ensuring that the system works at a stable speed.
Pressure regulating valve: by adjusting the pressure of the hydraulic oil, ensure that the equipment always maintains the working pressure range during work to achieve the required bending force.
One-way valve and check valve: ensure that the hydraulic oil can only flow in the predetermined direction to avoid system failures caused by reverse flow.
Overflow valve: used to release excess pressure in the system, avoid damage to the system caused by overpressure, and protect the safety of equipment.

Application Scenarios
High-pressure bending machine valve group is widely used in bending machine systems that require high bending force and high-precision control, and is suitable for processing thicker and harder metal sheets. Specific application areas include:
Heavy sheet metal processing: such as bending and stamping of thick plates.

Maintenance and Care
The maintenance of the high-pressure bending machine valve group is crucial for the long-term stable operation of the equipment. Common maintenance measures include:
Regularly check the hydraulic oil: keep the hydraulic oil clean, check the oil level and oil quality, replace inferior oil in time, and avoid impurities from entering the valve group.
Check the sealing of the valve group: Regularly check the sealing of each valve to prevent leakage and ensure the operation of the system.
Cleaning and lubrication: Keep the valve group clean, avoid dirt from entering, perform lubrication and maintenance regularly, and reduce wear.
Regularly check the pressure and flow settings: Regularly calibrate the pressure and flow settings of the system to ensure stable performance of the valve group.
Replace worn parts: Replace damaged or aged valve group parts in time according to the frequency of use and working environment to maintain system stability.
