[CN 201610133432.9] Energy-saving drive system of hydraulic unit and coordinated control method thereof
[CN 201610133432.9] A hydraulic unit energy-saving drive system and its coordinated control method Title: A hydraulic unit energy-saving drive system and its coordinated control method Application number: CN 201610133432.9 Applicant: Hefei University of Technology Application date: 2016-3-9 Patent type: Invention application The present invention discloses a hydraulic unit energy-saving drive system and its coordinated control method, characterized: A valve array connection is established between multiple hydraulic presses and the shared driving system. Through the change of valve array state, the corresponding driving area is selected to provide energy for the hydraulic press, so as to realize the efficient and orderly sharing of the driving system by the hydraulic press group. In the process of action coordination of the hydraulic press group, the design condition is that the pressing area continuously provides energy for the hydraulic press group, and the position and time of the movable beam movement are mixed and coordinated, the time error is adjusted for the part that exceeds the allowable error range to ensure the continuity and accuracy of the forming process of each hydraulic press. The invention can realize the effective operation of the energy-saving drive system of the hydraulic unit, and ensure the action time and position accuracy of each hydraulic machine.
