Description

Technical Field

[0001] The utility model relates to the technical field of servo hydraulic presses, and more specifically to a supporting hydraulic system for a high-speed servo hydraulic press. Background Art

[0002] Servo hydraulic press, also known as servo oil press, is a new type of energy-saving and efficient hydraulic press. It uses a servo motor to drive the main transmission oil pump, reduce the control valve circuit, and control the hydraulic press slide. It is suitable for stamping, die forging, press fitting, straightening and other processes, and has a wide range of application prospects.

[0003] At present, when using a servo hydraulic press, the servo motor drives the hydraulic oil pump to operate, thereby extracting the hydraulic oil in the oil tank into the oil pipe, so that the hydraulic oil enters the hydraulic cylinder through the oil pipe, thereby controlling the movement of the hydraulic rod to form a complete hydraulic drive system. However, the hydraulic drive system is not convenient for positioning during the process of driving the actuator to perform action feeding, and it is not convenient to improve the stability of the actuator during the action feeding process. In view of this, we propose a hydraulic system for a high-speed servo hydraulic press. Utility Model Content
