Eaton South Bend Adds Cross-Wedge Rolling | Forging
Cross-wedge rolling is a warm forging process for plastic deformation of cylindrical forms into axis-symmetrical parts. In a standard hammer forging process, a steel workpiece is heated and formed to a desired shape by impact. In Eaton's new process, the preforms are heated to 2,200°F and rolled to form the transmission shafts.
Review Current Trends in Cross Wedge Rolling for Part Forming
Cross wedge rolling (CWR), as an efficient metal plastic forming process, has always been investigated perseveringly by many nations' scholars for a number of years. Currently, with the fast development of economy, the increased demand is asked for various stepped shaft in different departments, especially in
Analysis of Square Billet Cross Wedge Rolling Process ...
The aim of this paper is to determine whether the train axle cross wedge rolling(CWR) using square billet as blank is available or not. Based on numerical simulation software DEFORM-3D, we built the finite element model. And the whole forming process was simulated successfully. The stress and strain distributions of workpiece in the process were analyzed.
