Abstract

Die Erfindung betrifft eine Vorrichtung (1) zum Aufweiten von Rohren mit einem Grundkörper (5), der an dem Gehäuse (3) eines Pressgerätes (2) fixierbar ist, einem in dem Grundkörper (5) um dessen Längsachse (X) drehbar und axial verschiebbar gehaltenen Kegel (7), der an seinem einen axialen Endbereich mit einem Stellelement (4) des Pressgeräts (2) koppelbar ist und an seinem andern Endbereich eine mit einem Aufweitkopf (21) in Eingriff bringbare Kegelspitze (8) aufweist, welche dadurch gekennzeichnet ist, dass der Kegel (7) axial unterteilt ist, wobei ein erstes Teilelement (7a) die Kegelspitze (8) trägt und ein zweites Teilelement (7b) mit dem Stellelement (4) koppelbar ist, und wobei die beiden Teilelemente (7a, 7b) insbesondere durch ein Gleit- oder ein Wälzlager (11) axialfest miteinander gekoppelt und um die Längsachse (X) relativ zueinander drehbar gelagert sind.
