Abstract

Bei einem Verfahren zum Umformen eines einen Profilraum aufweisenden Ausgangsprofils (10, 10x, 15, 16) od.dgl. Werkstückes mittels eines in dem abgedichteten Profilraum durch ein strömbares Wirkmedium erzeugten Innenhochdruckes zu einem Endprofil -- insbesondere zum Umformen bis zur Anlage des Endprofils an die Wandung eines Formraumes -- wird vor dem Umformen durch Innenhochdruck das Ausgangsprofil in Abstand zu seinen freien Enden sowie quer zu seiner Längsachse zu einem Querschnitt mit günstigen Biegeeigenschaften geformt. Während des Biegevorganges wird die Mittellinie des Bauteils ausgeformt sowie durch Innenhochdruck dessen Querschnitt verformt.
