Abstract
Bei einer Vorrichtung zum indirekten Strangpressen eines Hohlprofils aus einem Bolzen (B), insbesondere einem Aluminium-Hohlbolzen, der von einem Druckstempel (16) einem Formgebungsquerschnitt (25) einer Matrize (10) zuge führt wird, ist die Matrize (10) von einem Blockaufnehmer (3) überfahrbar und ihrem Formgebungsquerschnitt ein die Innenkontur des Hohlprofils bestimmender Dorn (17) zuge ordnet. In a device for indirect extrusion a Hollow profile from a bolt (B), in particular a Hollow aluminum bolt driven by a pressure stamp (16) a shaping cross section (25) of a die (10) the die (10) is guided by a block pick-up (3) can be driven over and its shape cross section Internal contour of the hollow profile determining mandrel (17) arranges.
Dem Formgebungsquerschnitt (25) ist dabei an der Matrize (10) in Pressrichtung (x) eine Formkaverne (30) unmittelbar vorgeschaltet, deren radiale Erstreckung grösser ist als die Weite (d) des Formgebungsquerschnittes. The shaping cross section (25) is on the Die (10) in the pressing direction (x) a molding cavern (30) immediately upstream, their radial extension greater is the width (d) of the shaping cross section.
Diese Formkaverne (30) kann entweder in die zum Druckstempel (16) gerichtete Matrizenfront (12) oder in die zur Matrizenfront (12) gerichtete Druckstirn (24) des Druck stempels (16) eingeformt sein. This shaped cavern (30) can either be in the Stamp (16) directed die front (12) or in the pressure forehead (24) of the pressure directed towards the die front (12) stamp (16) be molded.
