The servo hraulic system improves the pressure and flow control of the hraulic pump station from valve control to pump control. With the double closed-loop control of pressure, the flow can significantly improve the performance of the hraulic press, achieve higher accuracy, fast response speed, energy saving, low-speed stability, less noise and low oil temperature. It significantly reduce the maintenance cost compared with the traditional hraulic press brake machine. The machine body build with as one piece welding structure, ensure the machine accuracy and also convenient for transportation and handling. The hraulic system adopts an integrated control system, simplify the hraulic tube connection & transmission, improve working stability of the machine and nice appearance. The worktable is equipped with a mechanical deflection compensation mechanism to ensure high geometric accuracy in the whole bending length. Lower noise generate by the hraulic servo press, more working friendly especially for machine operator.
1. The main cylinders on both sides of the electric-hraulic servo bending machine simultaneously adopt proportional hraulic servo valve, hraulic control system and linear scale to form a closed-loop control, which is independently controlled by control System. It make sure the data feedback is accurate and to ensure slide block operation accuracy.
2. The hraulic bending machine has high strength and good rigidity; hraulic double cylinder transmission, mechanical block, torsion shaft synchronization are stable, reliable operation and high accuracy; The rear block distance and slide stroke using electric adjustment and manually fine-tuning, and equipped with digital display device for convenient and quick operation.
3. CNC hraulic plate bending machine is operated with special design CNC control system; Multi-steps programming function, can automatic set the program for multi steps operation, continuous different positioning, automatic and accurate adjustment of rear and slide block position, bending counter, real-time display of total quantity of parts processing, memorized last position, programs and parameters of the back-gauge block ; the back-gauge block adopts by imported ball screw and linear guide rail to ensure the higher positioning and operation accuracy.
4. The electric-hraulic servo CNC bending machine is mainly driven by the servo motor, so the motor will stop if the machine is not operate and no electric energy is consumed, which aligned with the requirements of modern environmental protection and energy saving. The servo motor is more easy to be controlled, the processing accuracy is higher, which is perfectly meet the demand of the related industry.
