The function of servo hydraulic press

Servo hydraulic press

Servo hydraulic press according to the power source is mainly divided into hydraulic and servo two categories, the largest number of servo hydraulic, in order to avoid the shortcomings of poor positioning accuracy, the use of pressure mode, rely on tooling to ensure positioning accuracy, for large parts or non-standard parts need to use servo hydraulic press to ensure positioning accuracy. The new servo hydraulic press is driven by AC servo motor. Through the output force of high precision hydraulic cylinder, the rotating motion of servo motor is transformed into the linear motion of hydraulic cylinder. The high precision load sensor is used to collect thrust value to realize pressure control, and the displacement sensor is used to output position signal to realize position control. In addition, the position sensor such as grating ruler can be used to realize full closed-loop position control, so as to avoid the position error caused by the frame deformation and realize the precision pressing operation without relying on the mold.

Advantages of servo hydraulic press:

1. You can customize, store and call 100 sets of press-mounting programs, and choose from three press-mounting modes to meet your different working procedure needs.

2. Through the USB interface, the press assembly data can be stored in the flash disk, to ensure the traceability of product processing data, convenient production quality control management.

3. Because the machine itself has accurate pressure and displacement control functions, there is no need to add hard limit on the tooling. Processing different specifications of products only need to call different press-assembly procedures, so can easily achieve a multi-purpose machine and flexible group line.

Main functions and characteristics of servo hydraulic press:

1. Accurately control the pressure installation output of the equipment and display the real-time output of the equipment;

2. Real-time display of the current pressing position with 0.03MM as a unit;

3. Real-time description of the force and displacement of the pressing curve;

4. The rigidity of the product can be tested;

5. It can store the press assembling parameters of multiple sets of equipment, so as to facilitate the next use;

6. It can store the pressed data.

7. Press data can be saved into EXCEL format.

8. Energy saving: the servo system adjusts the power output in real time according to the process requirements, and the power saving effect is 15%-70%;

9. High efficiency: high speed response of servo system, improving production efficiency by about 10%;

10 Stability: special PQ decoupling control scheme and multi-stage PID control technology, effectively control the pressure overshoot,
