Abstract
The paper presents the results of a thermo-mechanical analysis of the rolling two stepped shafts. One of the shafts has a toothed step with skew teeth, while the other has a worm winding in the shape of a trapezoidal screw. The shape of the rolling tools resembles that of the tools used in the Roto-Flo rolling method; yet unlike in Roto-Flo, the shafts are hot-rolled and no centres are used to stabilize the position of the workpiece during the forming process. For the calculations made with use of the DEFORM-3D process simulation system it has been assumed that the rolled shafts are made from 2618 aluminium alloy. As a result of the calculations made, it has been found that the toothed stepped shafts can be formed in one pass by means of the cross rolling process. Additionally, the temperature and strain distribution in the rolled product have been determined as well as some data concerning the forces which are necessary for the rolling process have been obtained.
