Abstract
The shaft is fabricated from a preformed semi- finished product with outer radial raised parts, in an internal high pressure forming process. To move material into the forming zone during the process when the tool is closed, the raised parts are charged with an axial load. The tool (11) consists of a divided block with internal shaping showing a group of raised parts. A first axial block (16) has an aperture enclosing a raised part (7,5,3), while its end face (18) facing the other axial block (15) loads the next raised part (8). The second block loads the neighboring raised part (9). A central block (12) encloses the semi-finished product (1) between the loaded parts.
