Abstract

Die Vorrichtung (1) weist zwei bezüglich ihrer Mittelachsen koaxial zueinander ausgerichtete Spannaggregate (3, 4) für ein Metallrohr (2) auf. The device (1) has two coaxially with respect to their center axes aligned clamping units (3, 4) for a metal tube (2). Ein 1. Spannaggregat (3) mit radial verlagerbaren Formwerkzeugen ist auf einem Grundgestell (GG) befestigt und über zwei Längsführungen (9) mit einer Widerlagerkonsole (10) verbunden, die ebenfalls auf dem Grundgestell (GG) befestigt ist. 1. clamping unit (3) with radially movable shaping tools is mounted on a base frame (GG) and two longitudinal guides (9) connected to an abutment bracket (10) also on the base frame (GG) is attached. Die Längsführungen (9) dienen der Verlagerung eines 2. Spannaggregats (4) mit radial verlagerbaren Haltewerkzeugen. The longitudinal guides (9) are used for displacement of a second clamping unit (4) with radially displaceable holding tools. Das 2. Spannaggregat (4) ist durch einen Vorschubzylinder (13) relativ zum 1. Spannaggregat (3) verlagerbar. The second clamping unit (4) by a feed cylinder (13) relative to the first clamping unit (3) displaceable. Das 2. Spannaggregat (4) ist mit einem Rohrdorn gekoppelt, der auf einem sich von der Widerlagerkonsole (10) aus durch das 2. Spannaggregat (4) bis in das 1. Spannaggregat (3) erstreckenden kanalisierten, an eine hydraulische Hochdruckquelle (29) anschließbaren Innendorn (19) gleitend geführt. The second clamping unit (4) is coupled with a tubular mandrel, the channeled extending on from the abutment bracket (10) through the second clamping unit (4) into the first clamping unit (3), (a high-pressure hydraulic source 29 ) connectable inner mandrel (19) slidably guided.
