ABSTRACT:
An extrusion arrangement is disclosed for manufacturing hollow-profile workpieces made of metal, including an extrusion die which is guided in an extrusion chamber and compresses material situated in the extrusion chamber. For forming an extruded hollow profile, the extrusion die presses the material through a bottom die arranged on a head-side end of the extrusion chamber, a forming of the extruded hollow profile taking place by means of internal high pressure during the emerging from the bottom die. Advantageously, a plurality of forming tools are provided which can be alternately arranged adjoining the outlet opening of the bottom die for receiving an extruded hollow profile and its forming, and, for cooling and releasing the formed extruded profile, the tools can be removed from the bottom die.
