Hydraulic presses, including a frame (2), an operating platform (1), and eight cylinders, with a piston rod (3) inside each cylinder. The distinctive feature is the presence of a tension cylinder (6) on top of the cylinder, which is a brand of new energy hydraulic presses. The piston rods within the cylinders are hollow, and the tension cylinder's piston rod (7) passes through the hollow section of the cylinder's piston rod. This utility model utilizes dual or multi-cylinder piston rods for a single process of metal sheet stretching and shaping, featuring a scientifically designed structure, easy operation, and convenience. The hydraulic presses manufactured according to this novel design will undoubtedly bring positive operational effects to the metal hydraulic press industry and represent a significant breakthrough for metal sheet stretching equipment, particularly in the automotive manufacturing sector.
Enhanced the control characteristics of the forging hydraulic press hydraulic control system, reduced the pressure surge of the return cylinder, improved the system's rapidity, and applied it in the actual forging hydraulic press production process, verifying the correctness and applicability of the proposed control strategy. Based on experimental research, investigated the control characteristics of switch-type rapid forging circuits, differential overflow rapid forging circuits, and proportional control rapid forging circuits, analyzed and compared their features and control characteristics, and provided corresponding computerized rapid forging processes. Conducted experimental research on the new energy-saving accumulator rapid forging circuit, proposed the basis for calculating the selection of accumulators, demonstrated the feasibility of energy-saving rapid forging using accumulators, and verified the correctness of the mathematical model for the accumulator and accumulator rapid forging circuit in new energy hydraulic press equipment.
Based on the structural characteristics of the overhead beam on a large-scale free forging hydraulic press, a finite element model was established using the large-scale general-purpose finite element analysis software I-DEAS. Static finite element analysis and calculations were conducted on the overhead beam. The operation method of the new energy hydraulic press was studied, focusing on the structural stress (strain) and displacement (deformation) of the overhead beam under full-load working conditions. The results indicate that the analysis and calculations using I-DEAS software are highly accurate, the established model and adopted calculation methods are reliable, and the structural design of the overhead beam is reasonable.
