Verfahren zur Herstellung einer Hohlwelle und Vorrichtung hierfür

The method involves reshaping the portion of solid semi-finished material (2) into a tubular intermediate product (3) through hole pressing process. The tubular intermediate product of the semi-finished material is separated for reshaping the intermediate product with respect to a cavity mold by hollow forward extrusion molding process, by using press ram and die. The extrusion molding process, round kneading process, flow-turning process or radial forging process is performed with respect to cavity mold for obtaining the hollow shaft. An independent claim is included for temperature regulating device.
