Abstract

Vorrichtung zum Biegen von Hohlprofilstäben (20), insbesondere für Abstandhalterrahmen für Isolierglasscheiben, wobei die Hohlprofilstäbe (20) zwei zueinander parallele Flanken (22) sowie eine Innenwand (23) und eine Außenwand (21) haben, welche die Flanken (22) miteinander verbinden,
  • mit einem Gestell (1),
  • mit einem vom Gestell (1) getragenen Biegewerkzeug (5) welches
    • eine Biegewange (12), welche um eine Schwenkachse (18) verschwenkbar ist, zum Biegen auf die Außenwand (21) des Hohlprofilstabes (20) einwirkt und eine Ausgangslage hat, welche sie vor dem Biegen einnimmt,
    • einen um dieselbe Schwenkachse (18) verschwenkbaren Gegenhalter (13) zum Anlegen an die Innenwand (23)
    • und ein der Innenwand (23) zugewandtes Biegewiderlager (14) aufweist, um welches herum der Hohlprofilstab (20) gebogen wird,
  • mit einer ersten Klemmeinrichtung, welche auf der der Biegewange (12) in der Ausgangslage abgewandten Seite der Schwenkachse (18) angeordnet ist und
    • ein erstes Klemmteil (15) zum Einwirken auf die Innenwand (23) und
    • ein zweites Klemmteil (16) zum Einwirken auf die Außenwand (21) des Hohlprofilstabes (20) aufweist.
Erfindungsgemäß ist vorgesehen, dass das Biegewiderlager (14) ein Scharnier ist, durch welches der Gegenhalter (13) und das erste Klemmteil (15) miteinander verbunden sind.
