Discussion of plastic forming for roller in PRSs

The existing production process of roller parts in PRS was analyzed, and the possibility of existing plastic forming processes using to manufacture roller was discussed. A new plastic forming process for mass manufacture of rollers was introduced, where the thread and spline shapes of the roller were formed by simultaneously rolling. The feasibility of the new plastic forming process was investigated by numerical simulation, and this process was also suitable for high efficiency precision manufacture of shaft part with similar features.
