Hydraulic Bending Machine Valve Group

The hydraulic bending machine valve group is a key control component designed for hydraulic bending machines. It is mainly used to control the oil flow, pressure, direction and speed of the hydraulic system. It accurately controls the flow of hydraulic oil to achieve the up and down movement of the bending machine tool, ensuring the accuracy of the bending machine during sheet metal processing. The hydraulic bending machine valve group is usually composed of multiple valves, control units and connectors, which work together to ensure the stable operation of the hydraulic system.

Product Features

High pressure bearing capacity: The material used can withstand the high-pressure working environment and ensure the stable operation of the bending machine under high load conditions.
Strong durability: The hydraulic bending machine valve group is designed to be sturdy and durable, and can withstand long-term and high-frequency use, extending the service life of the equipment.
Multiple protection design: Multiple safety valves and pressure protection devices are built in to prevent system overload or damage and improve operational safety.
Energy saving: The scientific hydraulic control technology is adopted to effectively control the flow and pressure of hydraulic oil and reduce energy consumption.
Quick response: The valve group can respond to operating instructions in a short time, ensuring that the hydraulic system can be quickly adjusted to the required state and improving production efficiency.

Main Components
The hydraulic bending machine valve group usually includes the following core components:
Pressure control valve: used to control the pressure in the system to ensure that the system works within the pressure range.
Flow control valve: adjust the flow of hydraulic oil to ensure the stability and uniformity of the oil flow.
Reversing valve: control the flow direction of hydraulic oil and adjust the direction of hydraulic system action.
Safety valve: automatically releases pressure when the system pressure is too high to protect the hydraulic system from damage.
Throttle valve: adjust the flow rate of hydraulic oil and control the speed of bending machine action.
Solenoid valve: used to automatically control the hydraulic system, and can control the action of the hydraulic system according to the instructions of the CNC system.

Working Principle
The hydraulic bending machine valve group drives the hydraulic cylinder and other actuators by controlling the flow, pressure and direction of hydraulic oil. The hydraulic oil is sent to the valve group under the action of the high-pressure pump, and each valve adjusts the flow and direction of hydraulic oil as needed. The operator controls the valve group to achieve the movement of the upper and lower molds of the bending machine, the adjustment of the bending speed, and the pressure control and other functions.
