Description
3.@..@: ..:.: Schrägwalzvorrichtung zun;teen von Metallrohren Die Erfindung betrifft eine Schrägwalzvorrichtung zum Aufweiten von Metallrohren mittels eines Dornes, der auf einer- an der Einführungsseite .der Vpxrichtung befindlichen Dornstange befestigt ist und bei der gemäß Patent 574 626 die durch den Walzvorgang sich ergebenden Stellungsänderungen des Dornes, die ungleiche Wandstärke der Rohre hervorrufen würden, durch Verstellen der Dornstange während des Walzens ausgeglichen werden.3. @ .. @: ..:.: Cross rolling device to; teen of metal pipes The The invention relates to a cross rolling device for expanding metal pipes by means of of a mandrel which is located on one of the insertion side .der Vpxrichtung Mandrel bar is attached and in the patent 574,626 by the rolling process resulting changes in the position of the mandrel, the unequal wall thickness of the tubes would be compensated by adjusting the mandrel bar during rolling will.
Bei der Einrichtung nach dem Hauptpatent wurde dieses Verstellen durch mechanische Einstellvorrichtungen bewirkt. Da bei Rohren mit großen Abmessungen außerordentlich starke Zugwirkungen auf die Dornstange entstehen, die mit mechanischen Mitteln allein nicht überwunden werden können, wird gemäß der Erfindung die Einstellung des Dornes durch einen durch Druckflüssigkeit, -luft oder -gas beeinflußten Kolben bewirkt.When setting up according to the main patent, this adjustment was carried out by causes mechanical adjustment devices. As with pipes with large dimensions extraordinarily strong tensile effects on the mandrel rod arise with mechanical Means alone cannot be overcome, the setting is according to the invention of the mandrel by a piston influenced by pressure fluid, air or gas causes.
Man kann nun diese Einstellvorrichtung auch noch mit einer mechanischen Einstellvorrichtung vereinigen, die dann -die Feineinstellung bewirken kann.You can now also use this adjustment device with a mechanical one Unite adjustment device, which can then effect fine adjustment.
Auf der Zeichnung sind mehrere Beispiele einer derartigen Vorrichtung dargestellt.Several examples of such a device are shown in the drawing shown.
Bei dem Beispiel nach Abb. i ist die Dornstange e mit der Kolbenstange 3 eines Kolbens 4 verbunden, der m einem Zylinder 5 spielt :und zwei Zu- und Ableitungen 6 und 7 hat, durch die Druckflüssigkeit oder auch -luft oder -gas eingeführt oder abgelassen werden können. Durch entsprechende Steue--rcingee kann man den Zu- oder Abfluß der Druckflüssigkeit o. dgl. ganz genau auf beiden Seiten des Kolbens regeln -'und diesem 'und damit dem Dorn eine genau bestimmte Stellung geben und ihn in dieser erhalten, d. h. wieder nachstellen, wenn etwa die Dornstange während des Walzens durch Erwärmung oder Zug ihre Länge verändert haben sollte.In the example according to Fig. I, the mandrel rod e is with the piston rod 3 of a piston 4 connected, which plays m a cylinder 5: and two supply and discharge lines 6 and 7 has introduced or through the hydraulic fluid or air or gas can be drained. With the appropriate control unit, you can access or Regulate the discharge of the hydraulic fluid or the like precisely on both sides of the piston -'and this' and thus give the mandrel a precisely defined position and put it in receive this, d. H. readjust again if, for example, the mandrel bar during the Rolling should have changed their length by heating or pulling.
Wie Abb. 2 zeigt, kann die hydraulische oder mit Luft oder Gas arbeitende Einstellvorrichtung auch mit einer mechanischen Feineinstellvorrichtung vereinigt werden, die aber iunabhängig von der ersteren bedient werden kann.As Fig. 2 shows, it can be hydraulic, air or gas Adjustment device also combined with a mechanical fine adjustment device which can be operated independently of the former.
Der Zylinder kann ausschwenkbar angeordnet werden.The cylinder can be arranged so that it can be swiveled out.
