Abstract：

By analyzing the working principle and the structure characteristics of servo drive forging press, a 3D model was built by modeling software. When the maximal roll forging force of 250 kN was applied to forging roll in the process of four passes respectively,the deformation of forging roll along the height direction and the stress in the 250 mm servo drive forging press model were simulated by software adopting static analysis method through applying overall load and analyzing components. The results show that in the four passes deformation, the second pass deformation is the largest with the sum value of upper and lower forging roll deformation 0.60991 mm. The stiffness is calculated as 409 kN·mm-1, and the admissible rigidity Ch is 350-500 kN·mm-1, so the rigidity standard is met. Furthermore, in the four passes stress analysis, the fourth pass Von-Mises value is the largest as 63.267 MPa which is less than the permissible stress 326.8 MPa and meets the stress requirement. Based on the above results, the stiffness and strength of the 250 mm servo drive forging press fully meet the actual requirements.
