Abstract：

When the multi-directional die forging hydraulic press, which uses pre-stressed wire-wound orthogonal preload frame as bearing frame, carried out ordinary die forging process along the single vertical direction, the force provided by vertical cylinder was directly loaded on the surface of blanks. Due to the influences of many factors including temperature deviation, uneven material and asymmetrical shape of blanks, etc., the bearing structure of multi-directional die forging hydraulic press was prone to the eccentric loading and under dangerous working condition. Therefore, the bearing capacity and deformation characteristic of the bearing structure in the multi-directional die forging hydraulic press 400 MN were studied by finite element analysis and 1∶10 model experiment under three eccentric loading states (front eccentric loading, right eccentric loading and front-right eccentric lading), and the conclusion was got that the deformation and bearing capacity of pre-stressed wire-wound orthogonal preload frame can meet the design requirement of multi-directional forging hydraulic press 400 MN.
