Simulation of the forging process with an additional macro-shift in “deform” software package

Abstract

The paper presents the results of computer simulation of the process of forging round blanks in the strikers of the new design. It is shown that the use of a radial joint of the faces has a favorable effect on the stress distribution along the entire length of the metal-tool contact. The analysis of models with different angles of inclination of flat faces showed that the best option is to use strikers with an angle of 30°, since in this case a fairly extensive distribution of strain over the cross section occurs in the workpiece with a significantly lower deformation force than when using strikers with an angle of 0°. The analysis of the technological parameters influence on the microstructure evolution showed that the most optimal workpiece heating temperature is 1000°C, while all 3 variants of the punch speed can be recommended for the implementation of this process in practice.
