摘要： A process for manufacturing a hollow body made of two mutually welded together metal bars which are flatly disposed on one another. Within an internal high-pressure forming tool in a closed position, the metal bars are widened by introducing a pressure fluid under a high pressure into the parting line existing between the metal bars, until they are placed on the die sinking of the forming tool defining the final contour while forming the hollow body. The metal bar composite is trimmed by a cutting operation, and the pressure fluid inlet area of the metal bar composite is cut off after the widening has taken place. In order to reliably manufacture a flangeless hollow body in a simple manner from two metal bars, the metal bars are seam-welded before entering into the forming tool, and the resulting metal bar composite is then trimmed by a beam welding process in the weld seam. Then for the expanding forming, the metal bar composite is charged into the forming tool such that its trimmed edges are situated within the die sinking of the forming tool, with the metal bar composite being clamped in only in the area of the pressure fluid inlet.

摘要： 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.

摘要： A device for continuous. casting of workpieces has a melting crucible, a filling device, and a forming tool provided with a temperature control system. The temperature control system of the forming tool is designed so that areas of the workpiece to be manufactured that have a greater wall thickness can be cooled to a greater degree and areas of the workpiece to be manufactured with a lesser wall thickness can be cooled to a lesser degree and/or heated. The solid-liquid interface of the workpiece is located in a plane that is at least approximately perpendicular to the vertical axis of the workpiece.

摘要： 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.

摘要： A process and an extrusion arrangement are suggested for cutting extruded hollow profiles while heated from the extruding process heat into the required lengths by means of a high-energy beam or jet moved along with the extruding operation. The interior of the extruded hollow profile is filled with a light-weight material at least at the cutting points. The light-weight material is advantageously an expansive foam mass, such as an aluminum foam or a plastic foam. The filling of the extruded hollow profile takes place either by coextrusion or by way of an arbor or a hollow-chamber bottom die of the extrusion arrangement.
