Abstract

This paper presents selected results of theoretical and experimental studies of rolling of stepped shafts and axles in a skew rolling mill. The theoretical research was based on numerical modeling using the finite element method. The Simufact-Forming software package was used for the calculations. Verification of numerical calculations was carried out under laboratory conditions in a numerically controlled skew rolling mill. In the conducted analysis, the technological possibilities of the skew rolling process of various axisymmetric parts in the CNC skew rolling mill were presented. In turn, based on numerical simulations, the state of stress and strain in the material during the rolling process was evaluated. The influence of selected technological parameters on the quality of rolled forgings was also determined. The results show that it is possible to produce stepped shafts in three-tool skew rolling processes. The state of stress that occurs in the process makes it possible to eliminate the danger of material cracking, while the applied rolling kinematics makes it possible to roll geometrically different products with a single tool set. In addition, the proposed three-tool skew rolling method makes it possible to permanently join two different materials to produce bimetallic semi-finished products.
