Abstract

Die Erfindung zeigt eine Lösung, wie der Durchmesser­ bereich von 6- oder mehr Walzenrichtmaschinen mit zur Durchlaufrichtung des Werkstücks schräg angestellten Richtrollen (7 bis 12) für Draht oder Rohre über die untere Grenze der nach dem Stand der Technik zu richtenden Werkstückdurchmesser hinaus erweitert werden kann. Dazu sind zwischen den aufeinanderfolgenden Richtrollen oder Richtrollengruppen Führungsdüsen (34, 35) für die Werkstücke vorgesehen, die den Zwischenraum zwischen den Rollen überbrücken und das Werkstück dort führen. Die Düsen sind an Tragarmen (26, 27) befestigt, die vom Rand der Maschine bis zwischen die Richtrollen ragen. Die Trag­ arme sind abnehmbar. Die Düsen werden nur beim Richten der kleinsten Durchmesser verwendet. Die Tragarme mit den Düsen sind in der Höhe verstellbar. The invention shows a solution like the diameter range of 6 or more roller levelers with Direction of travel of the workpiece inclined Straightening rollers (7 to 12) for wire or pipes over the lower one Limit of the state of the art Workpiece diameter can be expanded. To do this are between the successive straightening roles or straightening roller groups guide nozzles (34, 35) for the Workpieces provided that the space between bridge the rollers and guide the workpiece there. The Nozzles are attached to support arms (26, 27) from the edge protrude from the machine between the straightening rollers. The Trag arms are removable. The nozzles are only used when straightening the smallest diameter used. The support arms with the height of the nozzles is adjustable.
