Mechanism Research on Multi-Wedge Synchrostep Rolling Asymmetric Shaft-Parts by Cross-Wedge Rolling
Applied Mechanics and Materials, 2012Because most of the asymmetric shaft-parts have relatively large size in the axial direction, single-wedge cross-wedge rolling (CWR) exposes many imperfections, such as the huge roller, higher cost etc. The paper adopted finite element method (FEM) to simulate multi-wedge synchrostep CWR (MS-CWR) based on the typical asymmetric shaft-part, and gained ...

Cross-wedge rolling by means of one flat wedge and two shaped rolls
Journal of Materials Processing Technology, 2006Abstract A new cross-wedge rolling method which uses only one flat wedge and two shaped rolls is described in this paper. This new forming method was called wedge-rolls rolling (WRR). Within the confines of the research on WRR a number of simulations and experiments were made.

Precision forming machine with rolling plate cross wedge rolling
Science in China Series E: Technological Sciences, 2009Roller cross wedge rolling (CWR) machines have high rigidity, but sector dies are difficult to process. Plate CWR machines have low rigidity and need large floor space, but plate dies are easy to process. Neither roller CWR machine nor plate CWR machine can produce larger workpieces.

PARAMETRIC DESIGN OF SINGLE-WEDGE CROSS WEDGE ROLLING MODEL MECHANISM
Journal of Advanced Manufacturing Systems, 2008In order to speed up the simulation of single-wedge cross wedge rolling with the help of Pro/ENGINEER 2001 software, the source program to set up the CWR model is devised in the CWR modeling. As an example, the modeling technology of one part is studied in particular.

Influence Analysis of Block Wedge on Rolled-Piece End Quality in Cross Wedge Rolling
Applied Mechanics and Materials, 2011Rolled-piece end quality is one of key factors to decide material utilization ratio in cross wedge rolling (CWR). Good workpiece end quality can improve material utilization ratio effectively. In the paper, by adding the block wedge near the end of mould, it can block surface metal which flows faster in the axial direction and avoid the end concavity ...

Cross-Wedge Rolling at Pti Nas Belarus
Applied Mechanics and Materials, 2012The use of cross-wedge rolling method in metal-working industry allows development of new high-productive low-waste technologies designed to produce shaped billets for subsequent precision forging or other plastic forming processes. The paper deals with spheres of application, advantages and disadvantages of flat and roller cross-wedge rolling schemes.

Tools optimisation in cross-wedge rolling
Journal of Materials Processing Technology, 2003Abstract The present paper presents possibilities of the application of optimisation methods for the designing of the tools to be used in cross-wedge rolling (CWR) processes. A detailed description of the selection procedure for the forming angle α and the spreading angle β and the side wedge surface designing method has been presented.
