The paper discusses the problems of forming parts such as stepped shafts by cross wedge rolling (CWR). In industrial practice, this rolling process is performed at stages, i.e., in several passes, when large cross-sectional reductions are involved. The same can also be done using a different design of this forming process, namely, multi-wedge cross rolling (MWCR), in which the workpiece is simultaneously formed by several pairs of tools (wedges). This paper compares the above two methods with respect to forming a drive shaft. Wedge tools used in both forming processes are described, and the numerical results of the simulations performed to verify the adopted solutions are reported. The results demonstrate that the MWCR method offers more advantages than the classical CWR technique. Consequently, MWCR is then verified in experimental tests. The experimental results confirm that parts such as stepped shafts can be formed by the MWCR method.

“…The research and development works conducted so far have concentrated on the application of this method for producing automotive axle shafts [2,[5][6][7], stepped shafts [4,8] as well as railway axles, both solid [9] and hollow [3]. In addition to this, the method can be used for forming several short parts at one time.…”

“…This solution results in considerably reduced tool length, which, in turn, leads to an increase in the forming forces. In addition, the design of tool segments is more complicated, as the shape of the side wedges must allow for workpiece elongation caused by the impact of the central wedges [6][7][8].…”

The paper describes an innovative technological solution for producing balls from scrap rail heads. The proposed method consists in performing the following operations: the side pressing of a rail head to increase shape compactness, a process for forming a cylindrical rod by cross-wedge rolling (CWR), a CWR process for producing balls that have a diameter which is by 35% larger than that of the billet, quenching of the produced balls. Tools for the above manufacturing operations are designed, and numerical simulations are performed to verify whether the assumptions of the proposed technique are correct. A flat-wedge reversing mill is designed and constructed that enables performing the two abovementioned rolling operations without idle running, which makes the design innovative on a global scale. The implementation of the proposed method would enable producing balls for grinding media used in ball mills.

Rolling lamination forming of polyvinylchloride light conveyor was simulated using ANSYS12.0/LS-DYNA of FEM software. The filling condition of materials, the change of products’ geometry and the plastic deformation of products during the rolling forming process were studied. And the deforming displacement curves of the product in X direction during the process were also explored and discussed deeply. A simulation method of rolling lamination forming process was established and good results were achieved, which made a contribution to the theory of rolling lamination forming and is meaningful to the mould optimization, process parameters design and product quality control.
