Opis:: The paper presents experimental- model research results on the process of cross-wedge rolling of an axially-symmetrical element (stepped shaft). During research plastic mass on the basis of waxes in black and white colour was used. The aim of this experimental research was to determine the best option of forming in terms of values obtained and the course of forces. Physical examination was carried out using specialist machines, i.e. model and a laboratory cross-wedge rolling mill. Experimental analysis was carried out using billets with the temperature of 15°C, whereas the actual process was carried out for billet from C45 carbon steel of temperature 1150°C. The study compared the dimensions of the components obtained during rolling tests and forming forces obtained in the result of physical modeling with forces obtained during real tests.

Opis:: The paper deals with the concept of solid railway axle rolling using tools (rolls) in which the forming zones of individual workpiece steps are separated. Two types of tools were analysed, which were characterised by flat (typical solution) and convex (novel solution) forming surfaces of the wedge. Using the software Forge® NxT, simulations were performed of the rolling processes of the rail axle. Distributions of temperature, damage function, effective strain as well as force and torque courses were analysed. The results showed that it is possible to produce solid railway axles using the CWR method and confirmed the use of tools with a convex forming surface.

Opis:: The article presents the results of numerical analysis of splitting without waste on the basis of cross wedge rolling in double rolling mechanism. The analysed process concerns rolling the charge of V-shaped groove, and rotary bending causing the split of the material. In the calculations a method of finite elements (FEM) was used. The obtained results allowed detailed analysis of the splitting process in terms of the level of deformation, strains, material breaking, flow kinematics and strength parameters.

CWR
Opis:: Cross wedge rolling (CWR) is used for producing stepped axles and shafts as well as die forging preforms. In current industrial practice, CWR conducted with two tools is predominantly used, with the wedges mounted on rolls or flat tool plates. However, CWR can also be performed with the use of three wedge rolls. This paper begins with a review of previous studies on CWR conducted with the use of three rolls. After that, numerical simulations of two- and three-roll CWR processes for the same shaft are described. Obtained numerical results are then used to compare the two processes in terms of material flow kinematics, material temperature, stresses and strains, failure modes, as well as load and energy parameters. Finally, the Conclusions section presents the advantages of three-roll cross wedge rolling, providing a good starting point for further research on this promising forming method.

Opis:: The article presents an innovative method of manufacturing hollow rail axles using three combined wedge rolls. The proposed solution was evaluated using numerical simulation. Two cases of forming, differing in the wall thickness of the billet, were analysed. The geometry of the formed axles, distributions of the effective strain, temperature and damage function were presented. Moreover, the changes to the forces and torques acting on each roll were presented.
