[CN 201610326074.3] Energy-saving dual-actuator hydraulic press system and control method
[CN 201610326074.3] Title of an energy-saving dual-actuator hydraulic press system and control method: Application number of an energy-saving dual-actuator hydraulic press system and control method: CN 201610326074.3 Applicant: Hefei University of Technology Application Date: 2016-5-13 Patent Type: Application for the Invention The invention discloses an energy-saving dual-actuator hydraulic press system and control method, characterized in that the hydraulic press system includes a processing system and a positioning oil supplement system; the machining system includes an execution unit and a driving unit. The execution unit includes two groups of single-piston rod piston cylinders with the same structure, and the oil port of the rod cavity is connected through a throttle valve to realize complementary actions of the execution parts of the hydraulic cylinder. When one piston cylinder actuator descends, the other piston cylinder actuator rises, and vice versa, which can effectively improve the energy efficiency and working efficiency of the hydraulic machine, the positioning oil supply circuit is used to adjust the initial position of the double execution unit, so as to realize the adjustable relative position in the working process of the double execution unit and increase the flexibility of the system. The invention shares the driving unit between the dual execution units, improves the matching degree of the load and the driving unit, and reduces the energy loss of the processing process.
