The Working Principle and Development Trend of Servo Hydraulic Press

The servo-hydraulic press adopts a servo motor to control the flow and pressure of the oil pump and then cooperates with the pressure sensor to control each solenoid valve to control the slider of the hydraulic press. The hydraulic press produced can be called a servo-hydraulic press.

Ⅰ. Working principles of the servo-hydraulic press

The working principle of the servo-hydraulic press is that the servo motor directly drives the gear pump for the oil supply, and the pressure is stable. The main shaft of the servo-hydraulic press has high precision of downward repeated positioning and adopts pump control technology, which is energy-saving, with environmental protection, good rigidity, low noise, high efficiency, and good flexibility. The hydraulic servo system of some servo eletric press has been widely used in industrial control because of its unique advantages such as fast response speed, high load stiffness, and high control power. Therefore, relevant products such as 

hydraulic press for bearing fitting is popular.

1. The pressing depth, pressure holding time, and pressure can be input on the console. The operation is very simple.

2. During press fitting of the servo-hydraulic press, the whole process of pressure and displacement can be displayed on the LCD frequency, which can carry out online management of the whole process of press fitting, judge whether the products at any stage are qualified, and remove the defective products in time.

3. Its outer end is connected to the computer, which can press and save the data to the computer, so as to ensure the traceability of the data and facilitate management.

Ⅱ. The development trend of the servo-hydraulic press

Compared with an ordinary hydraulic press, the overall control of the system does not include a proportional servo valve or proportional pump. The service-driven hydraulic press has the advantages of energy saving, low noise, small temperature rise, good flexibility, high efficiency, and convenient maintenance. It can replace most existing ordinary hydraulic presses and has a wide market prospect. Compared with the traditional hydraulic press, the energy-saving effect is remarkable. According to the different processing technology and production beat, the servo motor hydraulic press can save 30% ~ 70% electricity compared with the traditional hydraulic press.

The hydraulic servo system makes the output of the system, such as displacement, speed, or force, change automatically, quickly, and accurately with the change of input. At the same time, the output power is greatly amplified. Hydraulic servo system has been widely used in industrial control because of their unique advantages such as fast response, high load stiffness, and high control power.
