The design concept of the electro-hydraulic servo CNC bending machine is to integrate the high precision of electrical control with the powerful hydraulic drive, achieving high-precision, high-efficiency, energy-saving, and environmentally friendly sheet metal processing through a closed-loop feedback system.
Its core design concept is reflected in the following aspects:
Electro-hydraulic Cooperative Control: The hydraulic system is controlled by electrical signals. A closed-loop control system is formed through electro-hydraulic servo valves and linear encoders, which monitor and adjust the slider position in real time, ensuring synchronous operation of the cylinders on both sides. The slider repeatability accuracy can reach ±0.01mm, with a maximum of 0.005mm.
Energy-Saving and High-Efficiency Design: A dual servo pump control system is introduced, reducing hydraulic oil consumption to only 1/3 to 1/5 of traditional systems. Standby energy consumption is reduced by more than 75%, and working speed is increased by 15%-25%, significantly improving energy efficiency.
Structural Optimization and Stability: The machine body adopts an all-steel plate welded structure, optimized through finite element analysis (ANSYS), and stress-relieved through tempering vibration to ensure rigidity and stability for long-term use.
Intelligent Compensation Technology: Integrating real-time dynamic compensation technology, the CNC system automatically adjusts hydraulic deflection compensation, reducing the impact of material deformation on workpiece quality and improving machining consistency.
High Automation and Expandability: Supports automatic selection, program calculation, and robot bending functions, and can be expanded to more than 18 axes to meet the machining needs of complex irregular parts.
User-Friendly Human-Machine Interaction: Equipped with a high-resolution touchscreen, supporting graphical programming, process simulation, and 3D display, lowering the operating threshold and reducing reliance on human experience.
