[CN 202011262548.5] Pretightening force parameter optimization method and frame device for frame of plate and frame hydraulic press
[CN 202011262548.5] Pre-tightening force parameter optimization method and rack device title for plate-and-frame hydraulic press frame: Pre-tightening force parameter optimization method and rack device application number for plate-and-frame hydraulic press frame: CN 202011262548.5 Applicant: Yanshan University Application Date: 2020-11-12 Patent Type: Invention Application The present invention provides a pre-tightening force parameter optimization method for plate-and-frame hydraulic press frame, which specifically includes the following steps: determining the size of pre-tightening force in plate-and frame structure, firstly, the stress of the O-shaped plate frame is analyzed, the tensile stiffness ratio of the first tie rod and the longitudinal side frame of the O-shaped plate frame is calculated, and the pre-tightening force of the first tie rod and the pulling force of the first tie rod after bearing are obtained according to the deformation balance condition. The specific position of the pre-tightening force on the O-shaped plate frame is determined according to the principle of minimum deformation after bearing. The frame structure realizes the assembly and longitudinal pre-tightening of the hydraulic machine frame structure through the pre-tightening nut, and the resultant force of the applied pre-tightening force is located inside the center line of the longitudinal side frame of the O-shaped plate frame. The invention improves the longitudinal rigidity of the hydraulic machine frame and prolongs the service life of the hydraulic machine by applying longitudinal pre-tightening force to the O-shaped plate frame in the hydraulic machine frame.
