Abstract

Die Erfindung betrifft ein Verfahren zum Biegen eines Werkstücks, bei dem (a) das Werkstück (1) mittels einer Halteeinrichtung (7, 8) in einem Halteeingriff gehalten, (b) in einem von der Halteeinrichtung (7, 8) in Längsrichtung vorragenden Biegeabschnitt (3, 4) mittels Reibschluss zwischen Biegewangen (11, 12) geklemmt (c) und durch Biegen umgeformt wird, indem die Biegewangen (11, 12) mit dem geklemmten Biegeabschnitt (3, 4) relativ zu der Halteeinrichtung (7, 8) mittels einer Rotationsbewegung aus einer ersten Biegewangenposition in eine zweite Biegewangenposition bewegt werden, (d) wobei zumindest ein überwiegender Teil der das Biegen bewirkenden Biegekraft mittels einer im Reibschluss wirkenden Reibkraft in den Biegeabschnitt (3, 4) eingeleitet wird.
