What Is Servo Hydraulic Press Machine?
A servo hydraulic press is a type of hydraulic press that combines electronic and hydraulic systems. It leverages the advantages of both, namely the high-pressure characteristics of hydraulic systems and the high precision characteristics of servo control systems. Its components typically include a servo motor, servo controller, sensors, hydraulic valve group, hydraulic pump, HMI, and more, forming a closed-loop control system. Servo hydraulic presses are widely used in various processes such as punching, die-cutting, drawing, and compression molding.
Advantages of Servo Hydraulic Press Machine
Energy saving
Servo hydraulic press, according to different processing techniques and production cycles, the servo-hydraulic press can save power by 20% to 60%.
(1) When the slider is quickly descending and the slider is stationary at the upper limit, the servo motor does not rotate, so no electric power is consumed. By comparison, the motor of the traditional hydraulic press still rotates at the rated speed and still needs to consume 20%-30% of the rated power.
(2) In the pressure holding stage, the servo motor speed of the servo-hydraulic press machine only supplements the leakage of the pump and the system. The speed is generally between 10 pm and 150 pm, and the power consumption is only 1% to 10% of the rated power.
(3) The efficiency of the servo motor is about 1% to 3% higher than ordinary ones and thus is more energy-saving.
Low noise
Servo hydraulic oil pumps generally use internal gear pumps, while traditional hydraulic machines generally use axial plunger pumps. Under the same flow and pressure, the noise of internal gear pumps is 5db～10db lower than that of axial plunger pumps.
Less heat emission and thus reducing cooling costs
The hydraulic system of the servo-hydraulic machine has no overflow heat, and there is no flow when the slider is stationary, so there is no hydraulic resistance heat. The heat emission of the hydraulic system is generally only 10% to 30% of that of a traditional hydraulic machine.
Less hydraulic oil consumption
Because the pump is at a state of zero speed and low heat emission most of the time, the oil tank of the servo-hydraulic machine can be smaller than that of the traditional hydraulic machine, and the oil can be used for a longer time. Therefore, the hydraulic oil consumed by the servo-hydraulic press machine is generally only about 50% of the oil consumed by the traditional hydraulic machines.
Fully closed-loop digital precision control
Servo hydraulic press machine is featured by a high degree of automation, good flexibility, and high precision. On one hand, the pressure, speed, and position of the servo-hydraulic press are fully closed-loop digital controlled, with a high degree of automation and good precision. On the other hand, its pressure and speed are programmable to meet the needs of various processes.
High efficiency
Through proper acceleration and deceleration control and energy optimization, the control speed of the servo-hydraulic machine can be greatly improved, and the work pace, which can reach 10/min～15/min, is several times higher than that of the traditional hydraulic machine.
Convenient maintenance
The hydraulic system is greatly simplified due to the elimination of the proportional servo hydraulic valve, speed control circuit, and pressure control circuit in the hydraulic system. The cleanliness requirements of hydraulic oil are much lower than hydraulic proportional servo systems, which reduces the impact of hydraulic oil pollution on the system.
High precision servo press is also called SERVO press, high precision servo press Assembly machine, electronic press, its working principle is driven by servo motor high precision ball screw for precision pressure assembly operation, high precision servo press can realize the closed-loop control of the whole process of pressing force and pressing depth in pressure assembly, thus realize the precision pressing of on-line quality management.
High precision: The C frame electric servo pres adopts servo control technology, which can accurately control pressure, displacement, and speed. The system accuracy is usually less than 1%, and the piezoelectric sensor accuracy can reach about 0.2%. The displacement resolution is as high as 0.001mm, ensuring the accuracy and consistency of the machining process.
Hydraulic Servo Press is a precision press that combines servo motor technology and hydraulic transmission technology. It controls the operation of the hydraulic system through a servo system, achieving precise control and adjustment of pressure.
High precision: H frame electric servo press drives high-precision ball screw through servo motor to achieve precise position control of the pressure head. At the same time, a highly sensitive pressure sensor is installed at the front end of the pressure head to collect real-time pressure and achieve pressure closed-loop control. This enables the equipment to have extremely high accuracy in pressure, displacement, and speed control.
Servo mechanical press utilizes servo motor drive to achieve precise control of mechanical motion through a precise control system. The high precision, high response speed, and programmability of servo motors enable servo mechanical press to achieve more complex and precise movements during the machining process, thereby improving machining accuracy and production efficiency.
The core of the servo hydraulic press machine lies in the coordinated operation of the servo motor and hydraulic pump. The rotation of the servo motor is converted into the flow of hydraulic oil through a hydraulic pump, thereby controlling mechanical motion. The servo control system can monitor and adjust the rotational speed of the motor in real time, ensuring the stability and accuracy of the hydraulic output. This working principle gives servo hydraulic presses significant advantages in energy efficiency, control accuracy, and response speed.

Hydraulic system
The hydraulic oil output by the hydraulic pump passes through the hydraulic cylinder to convert hydraulic energy into mechanical energy to achieve precise control of the workbench. The sensor detects the pressure, flow, speed and other parameters of the hydraulic system in real time, and feeds back the detection results to the control system.

How to Maintain Servo Hydraulic Press Machine
Anti-wear hydraulic oils No. 46 and No. 68 are recommended for working oils. Oil temperature ranges from 15 to 60 degrees Celsius.
Oil is filtered strictly before it is allowed to be added to the tank.
The working oil should be replaced once a year, and the first time should not exceed three months.
The slider should be injected with lubricating oil regularly, the surface of the column should be kept clean regularly, and the oil should be injected before each operation.
The maximum allowable eccentricity of concentrated load is 0.5 mm under nominal pressure of 100 tons. Excessive eccentricity can easily cause tension injury of column or piston rod or other undesirable phenomena.
Calibration and inspection of pressure transducers every six months to one year.
When the machine is out of service for a long time, the surface of each additional part should be scrubbed and coated with rust-proof oil, and the slider should be lowered to the lowest limit before power failure.
