[CN 202210339899.4] A High-power Electro-hydraulic Control Press System
[CN 202210339899.4] Title of a high-power electro-hydraulic controlled press system: Application number of a high-power electro-hydraulic controlled press system: CN 202210339899.4 Applicant: Taiyuan University of Technology Application Date: 2022-4-2 Patent Type: Invention Application The present invention provides a high-power electro-hydraulic controlled press system, which belongs to the technical field of presses. The press system includes: an execution unit connected with the movable beam of the press to drive the movable beam to move; the hydraulic drive unit is connected with the execution unit, and is used for supplying oil to the execution unit and storing the dynamic potential energy of the movable beam, and assisting the execution unit to drive the movable beam to move; the electric drive unit is respectively connected with the execution unit and the hydraulic drive unit, and is used for The hydraulic drive unit and the execution unit provide power and control the operating speed of the execution unit. The hydraulic-electric hybrid drive is used to control the operation of the press, which reduces the throttling loss during the rapid lowering and return of the movable beam of the press, and at the same time, the hydraulic drive unit can recover the dynamic potential energy of the movable beam, thereby improving the energy efficiency of the system.
