[CN 201810813537.8] An Energy-saving Low Vibration and Fast Response Hybrid Control Servo Hydraulic Press Hydraulic System
[CN 201810813537.8] An energy-saving low-vibration and fast-response hybrid control servo hydraulic machine hydraulic system Title: An energy-saving low-vibration and fast-response hybrid control servo hydraulic machine hydraulic system Application Number: CN 201810813537.8 Applicant: Wuhan University of Technology Application Date: 2018-7-23 Patent Type: Invention Application The present invention proposes an energy-saving low-vibration and fast-response hybrid control servo hydraulic machine hydraulic system, including single-acting working cylinder, double-acting fast-forward cylinder, workbench, working hydraulic circuit, fast-forward hydraulic circuit, controller and displacement sensor. The piston rods of single-acting working cylinder and double-acting fast-forward cylinder are connected with the workbench. The working hydraulic circuit and fast-forward hydraulic circuit respectively control the reciprocating motion of single-acting working cylinder and double-acting fast-forward cylinder. The input end of the controller is connected with displacement sensor, the output end is respectively connected with the working hydraulic circuit and the fast-forward hydraulic circuit, and the displacement sensor is installed on the workbench. The invention can greatly improve the response speed of the hydraulic system, improve the production efficiency, reduce the vibration amplitude of the worktable in the forging process, and has better energy saving.
