Advantages of Servo Hydraulic PressUpdate：2022-11-16 Hits：208
In recent years, hydraulic presses have made great progress in our country, but due to their high price and long production time, hydraulic presses have also undergone great changes. Due to the high cost, complex structure and large capital occupation of large-scale hydraulic presses, many hydraulic presses that can be used for large-scale stamping are still blank. Servo hydraulic presses are the largest share of mechanical hydraulic presses. The development of servo hydraulic presses is directly related to the development of other related industries. The important components of the servo hydraulic machine will inevitably affect the accuracy of the servo hydraulic machine.Compares hydraulic presses, points out the application status and development trend of servo hydraulic presses, and the structure types of friction hydraulic presses, screw hydraulic presses and clutch hydraulic presses. I also believe that in the near future, servo hydraulic presses will replace the current role of hydraulic presses in the field of forming.
Drive mode:
The servo hydraulic press uses a high-precision ball screw driven by a servo motor for pressure installation and operation, and the pressure is directly reversed by the servo motor; in general, the hydraulic press is driven by a motor, and the hydraulic cylinder applies pressure through the oil pipe and the valve body after the reversing valve changes direction. cause a certain loss.
Energy saving and environmental protection:
Servo motors are used in precision CNC electro-hydraulic presses. In standby, the motor will not spin, and the speed and power will change when the pressure is installed. For ordinary hydraulic presses, the motor is always rotating during standby, which requires a certain amount of power consumption. It also spins at a constant speed, with higher power consumption. Normal motors are noisier than servo motors.
Precise Control:
The precision servo hydraulic press can set multiple stroke speeds within a certain range, accurate displacement stop, accurate stop, accurate pressure stop, etc. Generally speaking, hydraulic presses are affected by the sealing of pipes, valve bodies and cylinders. Precision control cannot be very high, many of which are achieved through mechanical limitations. If you want to improve the accuracy of the hydraulic press, the equipment cost will far exceed that of the hydraulic press, and the control will be more complicated.
Precision electronic hydraulic press has the following functions:
Online pressure installation quality judgment: The whole process curve of pressure loading force and displacement can be displayed on the LCD touch screen; the whole process control can automatically judge whether the product is qualified at any stage of operation, immediately remove 100% defective products, and realize online quality management;
The pressing force can be input on the control panel, pressing into the deep layer, the pressing time is equivalent to the quick pressing, the interface is friendly, and the operation is simple.
You can customize, store, and call 100 sets of press-fitting programs: seven press-fitting methods can be selected to meet your different process standards.
Connect the pressing data to the computer through the external port to ensure the traceability of product processing data and facilitate the control and management of production quality.
Since the servo hydraulic press machine itself has precise pressure and displacement control functions, no hard positioning tools are required. When producing products of different specifications, the multifunctional cord can be easily realized by calling different pressure installation procedures.
