Abstract

Maschine zum automatischen Biegen von Rohren und aehnlichen Werkstuecken mit einem Vorschubwagen fuer das Verfahren des Rohres in Laengsrichtung der Maschine, wobei der Vorschubwagen steuerbar angetrieben ist, sowie mit einer Biegevorrichtung bestehend aus mehreren Rollenpaaren zur Fuehrung des Rohres, sowie mit zwei Schlitten zur Aufnahme je einer Biegerolle zum rechtsgaengigen oder linkgsgaen gigen Biegen des Werkstueckes, wobei die Schlitten steuerbar und quer zur Vorschubrichtung des Rohres antreibbar sind, sowie mit einer Vorrichtung zum gesteuerten Drehen des Rohres um dessen Laengsachse. A machine for automatically bending pipes and similar workpieces with a feed carriage for moving the tube in Laengsrichtung of the machine, wherein the feed carriage is controllably driven, and having a bending device comprising a plurality of pairs of rollers for guiding the tube, and with two slides, each for receiving a bending roller for rechtsgaengigen or linkgsgaen Gigen bending of the workpiece, wherein the carriages are controllable and drivable transversely to the feed direction of the tube, and with a device for controlled rotation of the tube about its longitudinal axis.
