      Introduction to Optimization Design of Pre stressed Frame Column for Rapid Forging Hydraulic Press

      As the core equipment of the forging industry, the fast forging hydraulic press plays an important role in promoting the upgrading of traditional industries and driving the coordinated development of upstream and downstream industrial chains. The rationality of the structural design of the column, as the main component of the prestressed frame of the fast forging hydraulic press, will affect the strength, stiffness, and service life of the prestressed frame of the fast forging hydraulic press. Therefore, it is necessary to optimize the design and analysis of the columns to reduce costs and increase efficiency while ensuring their structural strength. During the forging process of a fast forging hydraulic press, the deformation size of the column determines the adjustment of the guide gap size, and the rationality of the guide gap determines the accuracy of the forging process and the stability of the return process.
