[CN201611255251.X] Gear-rack driven double toggle force-boosting large-tonnage servo press and method thereof
[CN201611255251.X] A rack and pinion drive double toggle force-increasing large-tonnage servo press and its method Title: A rack and pinion drive double toggle force-increasing large-tonnage servo press and its method Application number: CN201611255251.X Applicant: Nanjing University of Science and Technology Application Date: 2016-12-30 Patent Type: Invention Application The present invention discloses a rack and pinion drive double toggle force-increasing large-increasing large-tonnage servo drive press and its main tonnage press and its working system, including a main body and its working, the main transmission system includes a servo motor, a reducer, a two-way rack and pinion mechanism and two sets of toggle mechanism with the same structure and symmetrical arrangement. The two ends of the two-way rack and pinion mechanism are connected with one set of toggle mechanism; The servo motor drives the reducer, the reducer is fixed on the beam of the fuselage, the reducer drives the two-way rack and pinion mechanism to move left and right, and the two-way rack and rack mechanisms drive the two sets of toggle, the two sets of toggle mechanisms drive the working slider to move up and down to realize the pressure processing of the press. The invention can obtain greater pressure in the pressurization zone near the bottom dead center, and the pressurization zone has a large range; the structure is simple and practical, the mechanisms on both sides are guaranteed to be synchronized during the movement, and there is a double between the fuselage beam and the slider Point support improves the anti-partial load ability of the press.
