[CN 201811024009.0] A Single Beam Cylinder Forging Hydraulic Press
[CN 201811024009.0] Title of a Single Beam Cylinder Forging Hydraulic Press: Application Number of a Single Beam Cylinder Forging Hydraulic Press: CN 201811024009.0 Applicant: Application Date of Huazhong University of Science and Technology: 2018-9-4 Patent Type: Application of the Invention The present invention belongs to the technical field related to metal plastic forming equipment. It discloses a single beam cylinder forging hydraulic press. The forging hydraulic press includes a body, a hydraulic cylinder and a hammer head, the body is formed with an operating space and a guide groove communicating with the operating space; the hydraulic cylinder includes a cylinder body, a plunger, a piston rod and a piston. One end of the cylinder body is formed with a working cavity, and the other end is partially located in the guide groove and is connected with the hammer Head is connected; one end of the plunger is provided with a blind hole, the other end is connected to the fuselage and is provided with a first oil hole communicating with the blind hole, a second oil hole penetrating the plunger, and a third oil hole penetrating the wall of the blind hole; the piston rod is connected to the cylinder body and arranged in the blind hole One end of the piston is arranged in the working cavity; by controlling the oil inlet and discharge states of the first oil hole, the second oil hole and the third oil hole, the cylinder can drive the hammer to work and return with different forces and speeds. The invention simplifies the structure, reduces the cost, and realizes the classification of forging pressure and speed.
