1. Principle of electro-hydraulic servo CNC bending machine

The electro-hydraulic servo CNC bending machine uses electro-hydraulic servo technology to realize CNC bending machine tools. After the workpiece enters the clamp of the bending machine, it undergoes plastic deformation under the pressure of the upper and lower templates to form the required angle. The machine tool uses an electro-hydraulic servo system to control the movement of the upper and lower templates, thereby controlling the bending angle and position.

The components of the electro-hydraulic servo system include electro-hydraulic servo actuators, hydraulic systems, circuits and controllers. Among them, the electro-hydraulic servo actuator is mainly composed of servo motor, servo valve and oil cylinder, etc., and is responsible for realizing the movement of the upper and lower templates. The hydraulic system provides working fluid pressure and oil flow, and cooperates with the electro-hydraulic servo actuator to ensure the accuracy and stability of the machine.

2. The use of electro-hydraulic servo system can achieve rapid response, effectively control the bending speed and strength, and ensure the stability and accuracy of the machine during the working process.

3. The base is welded with steel plates, which has high strength and rigidity, ensuring the stability and working accuracy of the machine during the entire processing process.

4. The upper and lower templates adopt pneumatic balanced side push devices, which can minimize the impact of inertial loads on the main machine and improve the accuracy of the bending angle and position.

3. Application fields of electro-hydraulic servo CNC bending machine

Electro-hydraulic servo CNC bending machines can be widely used in metal processing fields, such as aviation, aerospace, shipbuilding, automobiles, architectural decoration, communication electronics and other industries. It has a good effect in the processing of manufacturing large components, precision parts and high-strength materials, and the cost is relatively low and the production efficiency is high.
