Analysis of forging process of the yoke type forging using the results of numerical simulation

摘要

The paper presents the results of numerical modeling of the forging hot forging process of the yoke type forging used in the steering system realized on the crank press. The main purpose of the analysis was to use computer simulation to analyze and improve the industrial forging process. The thermomechanical model of forging process with deformable tools was developed using the Forge NX 2.0 software. Catia program was used to build models of forging tools. As a result of the modeling obtained, inter alia: temperature distributions and plastic deformations for the forging (taking into account thermally activated phenomena), as well as grain size changes and forging forces. The obtained results allow for a full analysis of the forging process, including: identification of potential forging defects (overlaps) and the influence of time and temperature of deformation on the grain size in the forging material, which in the future may allow using the forging heat for the planned heat treatment and obtaining a specific microstructure.
