Abstract
Extrusion arrangement for manufacturing bent workpieces, having an extrusion die which is guided in an extrusion chamber and compresses material situated in the extrusion chamber and presses it through a bottom die arranged on a head-side end of the extrusion chamber. At least two further bottom die elements are arranged behind the bottom die in a parallel adjoining manner and are displaceably and rotatably disposed such that their successive passage openings form an extrusion duct of a variable curvature and twisting. For producing hollow profiles, an arbor is provided in the interior of the extrusion chamber, whose extension extending through the outlet opening of the bottom die and into the passage openings of the bottom die elements consists of a plurality of segments which are movably connected with one another.
