Servo-hydraulic press is a kind of hydraulic press which has feedback device and can detect and feedback signals. Nowadays traditional servo-hydraulic press based on proportion-al servo valve control has been often used,but the study of this article is a new servo-hydraulic press based on the AC servo motor control. In this article, the hydraulic system of new servo-hydraulic press,and the electrical control system including the hardware component and software system have been mainly designed.

Valve Control

As we known, the energy efficiency of pump-control system is higher than valve-control system. So, using pump-control system to replace valve-control system has a positive meaning to improve the energy efficiency in hydraulic press machine. In order to research the performance of servo pump used in hydraulic press machines, the present study is conducted. First, a test bench for comparison of pump-control and valve-control system is established. In this test bench, the pump of former valve-control system and the servo pump are settled. These two pumps are switched by solenoid to supply oil for the hydraulic system. Then, host PC, target PC, I/O board and other hard-wares are connected. Soft-wares and the corresponding driver board are applied to collect data. In order to test the performances of the pressure, velocity and displacement under the condition of the valve-control system and pump-control system, the two systems are tested with the same working conditions. The performance of repeatability and energy efficiency are also obtained. The results show that it’s feasible to apply servo pump to hydraulic press machine. And under the pump-control condition, the velocity and pressure performance of press machine is more stable.
