Abstract

Die Erfindung betrifft eine Biegeanordnung zum Biegen kleiner und kleinerer oder werkzeugunabhängiger Biegeradien in ein rohrförmiges Biegeteil (10), die mindestens eine Biegeeinrichtung (2, 3) aufweist, in der die zur Durchführung der Biegefunktion erforderlichen Biegewerkzeuge (4a, 4b, 4c; 5) angeordnet sind, und zum Vorschub des Biegeteils (10) aufweist, wobei die Biegeeinrichtung (3) in Vorschubrichtung des Biegeteils (10) vor der Vorschubeinrichtung (3) angeordnet istThe invention relates to a bending arrangement for bending smaller and smaller or tool-independent bending radii in a tubular bent part (10), the at least has a bending device (2, 3) in which the to perform the bending function required bending tools (4a, 4b, 4c; 5) are arranged, and for feeding the bent part (10), the bending device (3) in the feed direction of the bent part (10) is arranged in front of the feed device (3)

Erfindungsgemäß ist vorgesehen, daß die Biegeanordnung (1) eine Domvorschubeinrichtung (40) aufweist, deren Dorneinsatz (43) in den durch die Biegewerkzeuge (4a-4c; 5) festgelegten Biegebereich der ersten Biegeeinrichtung (2) einschiebbar oder eingeschoben ist, und daß die erste Biegeeinrichtung (2) eine Einrichtung zum Ausgleich einer Ausschwenkbewegung des Biegeteils (10) bei dem durch die Biegewerkzeuge (4a-4c; 5) durchgeführten Biegevorgang des Biegeteils (10) aufweist.

Figure 00000001
According to the invention, it is provided that the bending arrangement (1) has a dome feed device (40), the mandrel insert (43) of which can be inserted or pushed into the bending area of the first bending device (2) defined by the bending tools (4a-4c; 5), and that first bending device (2) has a device for compensating for a pivoting-out movement of the bent part (10) during the bending process of the bent part (10) carried out by the bending tools (4a-4c; 5).
