Fem Simulation of the Cross-Wedge Rolling Process

The numerical results demonstrate that personal computers can today be used to model even the most difficult cases of the cross-wedge rolling process, in which complex shapes of the tools and thermal phenomena occurring during the forming process have to be taken into consideration. (PDF) New method of thread rolling - ResearchGateThe process is a combination of cross-wedge rolling and helical rolling, the lat ter being previously used for producing grinding media balls. This method involves the use of wedge-shaped rolls

A new method for manufacturing hollow valves via cross

Feb 01, 2017 · Cross wedge rolling-forging (CWR-forging) is an innovative process for local plastic deformation that is suitable for forming hollow valves. This paper presents the numerical and experimental results of hollow valve production using this new method. The most popular production methods are described. Then, this study examines the formation of such valves through CWR-forging.

NUMERICAL ANALYSIS OF THE CROSS WEDGE ROLLING

Z. PATER et al.:NUMERICAL ANALYSIS OF THE CROSS WEDGE ROLLING PROCESS (CWR) FOR A STEPPED SHAFT CONCLUSION The paper presented a thermo-mechanical model of cross wedge rolling for producing a stepped shaft. Us-ing the model and commercial software Simufact Form-ing, the rolling process for the shaft was simulated nu-merically. Numerical analysis of the skew rolling process for main Z. Pater, J. Tomczak, T. Bulzak, Lublin University of Technology, Lublin, Poland The paper discusses a new technique of skew rolling with three tapered rolls and its application to the production of long main shafts of steel that are used in light trucks. First, the design of this forming technique is described. Then the paper stresses the universality of this process, as the skew rolling (PDF) Numerical and experimental research on cross wedge Numerical and experimental research on cross wedge rolling hollow shafts with a variable inner diameter November 2019 Archives of Civil and Mechanical Engineering 19(4):1497-1510
