Abstract

Die Erfindung betrifft ein Profil-Dornschaft-Werkzeug (2) zum Biegen von offenen bzw. geschlossenen Hohlprofilen, beinhaltend einen Dornschaft (15), welcher mittels einer Fördereinrichtung in den Innenraum des Hohlprofiles ein- und ausführbar ist, wobei der Dornschaft (15) während des Biegevorganges sich auf einer Biegelinie zwischen mindestens zwei gegeneinander gerichteten, den Biegedruck applizierenden Rollen (11,12,13) befindet, wobei der Dornschaft (15) mindestens im Bereich der Biegelinie hoch druckfest und verschleißfest ausgebildet ist und/oder mittels eines Schmiermittels geschmiert wird. Der Dornschaft (15) kann dadurch höchste Druckbelastungen aufnehmen, hat gleichbleibend gute Gleiteigenschaften bei unterschiedlichsten Drücken, gewährleistet hohe Geschwindigkeiten des durchlaufenden Profils bei gleichzeitig hohen, aber materialschonenden Umformgraden. Auch können damit unterschiedlichste Materialien gebogen werden, wie z.B. Alu mit seinen Legierungen, Cu, Mg, Stahl, Cr-Ni-Mo-Stähle, Titan, Magnesium etc..
