Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen von Schraubennahtrohren aus Metallband, mit einem aus einer Vielzahl von Biegerollen zusammengesetzten Dreiwalzenbiegesystem, wobei die im Rohrinnern wirkenden Biegerollen an einem verstellbaren Rollenträger angeordnet sind.The invention relates to a device for producing screw seam tubes from metal strip, with a three-roller bending system composed of a plurality of bending rollers, the bending rollers acting inside the tube being arranged on an adjustable roller carrier.

Eine derartige Vorrichtung Ist durch die DE-AS 10 75 53o bekannt.Such a device is known from DE-AS 10 75 53o.

Bei dieser Vorrichtung ist der Rollenträger in Höhenrichtung verschieb- und verschwenkbar. Durch Verschwenken des Rollenträgers in Höhenrichtung wird eine gleichmäßige Höhenausrichtung der vorderen und hinteren Biegerollen unabhängig von der Größe der vertikalen Verbiegung des Rollenträgers erreicht.In this device, the roller carrier is displaceable and pivotable in the vertical direction. By swiveling the roller carrier in the vertical direction, a uniform height alignment of the front and rear bending rollers is achieved regardless of the size of the vertical bending of the roller carrier.

Die bekannte Vorrichtung gestattet jedoch nicht eine gleichmäßige Seitenausrichtung der vorderen und hinteren Blegerollen des Rollenträgers. Hierdurch kommt es an den vorderen und hinteren Biegrollen infolge der horizontalen Verbiegung des Rollenträgers zu unterschiedlichen Bandverformungen, die die Rohrdurchmessertoleranz ungünstig beeinflussen.However, the known device does not allow a uniform side alignment of the front and rear lead rolls of the roll carrier. This results in different strip deformations at the front and rear bending rollers due to the horizontal bending of the roller carrier, which adversely affect the tube diameter tolerance.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß der Rollenträger auch in Seitenrichtung verschwenkbar ist.The invention has for its object to provide a device of the type mentioned in such a way that the roller carrier can also be pivoted in the lateral direction.

  • at least one steering circle adjustment device assigned to a steering circle level,
  • an articulated rod acting in the direction of the pipe axis,
  • - A lifting device articulated at one end of the roller carrier and
  • - A height-adjustable suspension with an articulated bracket mounted in the central area of the roller carrier, a two-armed lever and a lifting device

are used.

Die der ersten Lenkkreisebene zugeordneten Lenkkreisverstellvorrichtung ist mit zwei Exzenterbolzen ausgeführt.The steering circle adjustment device assigned to the first steering circle level is designed with two eccentric bolts.

Die der zweiten Lenkkreisebene zugeordnete Lenkkreisverstellvorrichtung ist mit einem Exzenterbolzen ausgeführt.The steering circle adjustment device assigned to the second steering circle level is designed with an eccentric bolt.

Jeder Exzenterbolzen ist mit einem Antriebsmotor gekuppelt.Each eccentric bolt is coupled to a drive motor.

Die Hubgeräte sind mit je einem Antriebsmotor ausgerüstet.The lifting devices are each equipped with a drive motor.

Zur Steuerung der Antriebsmotoren ist ein Steuergerät vorgesehen.A control device is provided to control the drive motors.
