Ưu điểm của máy ép thủy lực servo và hướng phát triển
hydraulic metal press machine Compared with the traditional hydraulic press, the servo control technology applied to the hydraulic press has the following advantages:

Servo motor mainly relies on pulse to position. Every pulse received will rotate 1 pulse corresponding to the angle, the control accuracy of the servo motor alone can reach 1/1024 turns, combined with the corresponding sensors, can achieve accurate control of any position of the ram. Servo hydraulic press can optimize the movement curve compared with the traditional hydraulic press, and the appropriate slider curve can suppress the rebound of the plate pressing process and improve the accuracy between. hydraulic metal press machine
1.2 High flexibility
The slider movement curve can be optimized according to different production industries and molds, and special working characteristic curves can be designed to carry out difficult and high-precision processing and realize “free movement” of the slider. For example, the reciprocating motion curve can be used to press thin plate parts, which can effectively suppress the wrinkling phenomenon at the large curvature of deformation.
1.3 High efficiency
The number of ram strokes can be set in a wide range, and the ram speed and stroke can be easily adjusted. hydraulic metal press machine
1.4 Energy saving
Compared with mechanical presses, servo-hydraulic presses eliminate flywheels and clutches and use direct transmission, which greatly reduces the transmission link and lubrication, and is highly maintainable. There is no clutch to combine energy consumption, the motor stops after the ram stops, and there is no more motor and pulley idling, so energy consumption is significantly reduced. In ordinary mechanical presses, the flywheel idling energy consumption accounts for about 6% to 30% of the total energy consumption, clutch (mainly refers to the friction clutch energy consumption accounted for about 20% of the total energy, servo hydraulic press without flywheel and clutch, this part of the energy can be saved.
Although the servo control technology has shown strong vitality in the hydraulic press, there are still many key technologies that need to be improved: hydraulic metal press machine
