[CN 201610563245.4] Sliding block anti-torsion device for large tonnage short stroke single column hydraulic press
[CN 201610563245.4] A large-tonnage short-stroke single-column hydraulic press slider anti-torsion device Title: A large-tonnage short-stroke single-column hydraulic press slider anti-torsion device Application Number: CN 201610563245.4 Applicant: Hefei University of Technology Application Date: 2016-7-15 Patent Type: Invention Application The present invention discloses a large-tonnage short-stroke single-column hydraulic press slider anti-torsion device, it is characterized in that a first vertical plane and a second vertical plane that are spaced apart and parallel to each other are used to form a limit space, and a plane limit structure is arranged in the limit space. The first vertical plane is the side plane on the slider facing the side of the fuselage, and the second vertical plane is the side plane on the fuselage facing the side of the slider. In the limit space, four top support cylinders are arranged one by one according to the positions of the upper left corner, the cylinder seat of the top support cylinder is fixedly arranged at the corresponding position of the fuselage, and the rod end of the cylinder piston rod is against the first vertical plane; the top support cylinder is used to limit the first vertical plane to realize the plane limit of the slider. The invention sets an anti-torsion structure for the torsion moment that may exist in the process of pressing the workpiece, which can effectively ensure the reliable operation of the press and maintain the accuracy of the guidance control.
