[CN 201710765672.5] Double-station press execution system with machine-liquid mixing and control method thereof


[CN 201710765672.5] A double-station press execution system with machine-liquid mixing and its control method Title: A double-station press execution system with machine-liquid mixing and its control method Application No.: CN 201710765672.5 Applicant: Hefei University of Technology Application Date: 2017-8-30 Patent Type: Application for the Invention The present invention discloses a double-station press execution system with machine-liquid mixing and its control method, which are in the same vertical plane, A first hydraulic cylinder and a second hydraulic cylinder are symmetrically fixed to the press body. A rack and pinion transmission mechanism driven by a motor through an electromagnetic clutch and an electromagnetic brake is arranged between the first hydraulic cylinder and the second hydraulic cylinder. The rack and pinion transmission mechanism has a central gear and a first rack and a second rack located on the left and right sides of the central gear. The rotation of the central gear drives the first rack and the second rack to move vertically and reversely; the first rack forms a linkage structure with a moving part outside the first hydraulic cylinder through a first connecting rod, and the second rack forms a linkage structure with a moving part outside the second hydraulic cylinder through a second connecting rod. The invention effectively reduces the energy loss during the operation of the press by mixing the machine liquid, improves the working efficiency of the press, and improves the positioning accuracy of the executive parts of the press.
