Numerical Analysis of Feed Rate Influence on Hollow Hub Shape during Rolling Extrusion Process

Abstract:

This paper presents the results of numerical calculations of rolling extrusion process of a hollow hub. Due to the necessity of flanges manufacturing at both sides of the product, in the analyzed process of rolling extrusion, as additional tool limiting axial metal flow a rear bumper was implemented [1,. Numerical calculations of the hub forming process were conducted basing on finite element method, applying software Deform3D v.X in conditions of three dimensional state of strain. The obtained small shape faults, in the form of characteristic triangulation and small changes of the hub walls thickness, show that it is possible to conduct the further research works of experimental character, with the application of modernized aggregate for the rolling extrusion process PO-2.
