When the 60 MN free forging hydraulic press was reconstructed, the serious deformation of the tension plate and the serious swear of the main working table were found. For the above issues, an improved scheme for the main working table was put forward. Therefore, the laws of the deformation and the stress distribution with the two main working tables in the working state were analyzed by software ANSYS. Meanwhile, the processing properties of the manufacture, installation, usage and maintenance for main working tables were studied. It is concluded that when the overall structure of the main working table is under 60 MN pressure, even though both sides appear the 2.058 mm deformation, it can obviously increase the force area by the tension plate, decrease the deformation and the stress of tension plate. In addition, it embodies the advantages of the prevention of iron oxide leakage and the improvement of the lubrication, etc. The final result shows that the improved whole structure of the main working table is better than the fission structure.
