INVESTIGATION OF HOT FORGING PROCESS BY FEM SIMULATION

Abstract

The process of hot forging of steel is one of the most common industrial technologies. Designing this technology is a challenge because today complex geometries of finished products are obtained. The goal of FEM simulation is to generate the most realistic contact between the tool and the deformable material, both in volume and in the immediate vicinity of the boundary surfaces of the tool. FEM simulation by Qformof the hot forging process is a good way to prevent possible errors and problems of tool construction. Using the example of a complex forging, the paper analyzes the geometrical conditions of contact, the stress-deformation state within the deformable volume, and the constructive solution of the tool for hot forging in a closed die.
