Abstract：

According to the industry standard JB/T 12229—2015, the oblique angles of double-column hydraulic press were divided into 22°, 25°, 30°, 32.5° and 35°, respectively, the geometry parameters of hydraulic press body were changed by different oblique angles, and the weight of hydraulic press was also changed. For the body of double-column push-up hydraulic press with 5 MN nominal pressure, taking the oblique angle of hydraulic press as the variable, the strength and stiffness as the constraint conditions and reducing the weight of body as the goal, the design of body was optimized by finite element software ANSYS Workbench. Under the condition that no slotting occurs on the contact surface between column and cross beam, the minimum pre-tightening force under the center load and the eccentric load was simulated and calculated, and the influence rule of oblique angle on the pre-tightening force of hydraulic press was analyzed. Through the above analysis results, the influence trend of oblique angle on the weight of hydraulic press was studied. Thus the theoretical guidance for enterprises to choose the specifications of double-column hydraulic press is provided.
