Abstract

Um insbesondere herkömmliche Planetenschrägwalzwerke weiterzuentwickeln, schlägt die Erfindung eine Vorrichtung zum Walzen von Rohrluppen mit einem Planetenschrägwalzenwerk, mit einem Vorschubbett, mit einer Rohrluppenzufuhr, mit einem die Rohrluppe von dem Vorschubbett ausgehend durch das Planetenschrägwalzwerk schiebenden Rohrluppenvorschub, der zumindest einen Vorschubapparat aufweist, mit einer Dornstange und mit einem Domstangenhalter vor, wobei die Rohrluppenzufuhr einen axialen Rohrluppenzuförderer aufweist, der eine Rohrluppe axial in eine Bereitstellposition, die axial hinter dem Dornstangenhalter vorgesehen ist, fördert und wobei der Vorschubapparat zwischen Planetenschrägwalzwerk und Dornstangenhalter angeordnet ist, wobei sich die Walzvorrichtung dadurch auszeichnet, dass der Vorschubapparat einen Stößel aufweist.In particular, to further develop conventional planetary cross rolling mills, the invention proposes an apparatus for rolling tube billets with a planetary bevelling mill, with a feed bed, with a tube feed, with a tube feed advancing the tube billet from the feed bed through the planetary cross rolling mill, having at least one advancing apparatus, with a mandrel bar and with a mandrel bar holder, wherein the tubing feed has an axial tube feed conveyor that axially conveys a tube blank into a provision position provided axially behind the mandrel bar holder, and wherein the feed apparatus is disposed between the planetary cross rolling mill and mandrel bar holder, wherein the rolling device is characterized in that the feed apparatus has a plunger.
