Die Erfindung betrifft eine Maschine zum Abwälzen von kalt über die Stange gezogenen Rohren für eine Anlage nach Patent 706 573, bei der einer Ziehbank zwei Abwalzmaschinen zugeordnet sind, die auf einer Seite der Ziehbank angeordnet sind. Die Notwendigkeit der Anordnung von zwei Abwalzmaschinen ergibt sich aus der Tatsache, daß die Abwälzmaschine den engsten Querschnitt der Anlage bildet und die von der Ziehbank kommende Anzahl von Rohren nur mit Hilfe von zwei Abwalzmaschinen bearbeitet werden kann, wenn die -Leistungsfähigkeit der Ziehbänke voll ausgenutzt werden soll. Die Anordnung zweier Abwalzmaschinen üblicher Bauart nebeneinander hat einen sehr großen Platzbedarf zur Folge,, der bei den meist beschränkten Platzverhältnissen in der Rohrzieherei nicht zur Verfügung steht.The invention relates to a machine for rolling cold drawn over the bar Pipes for a plant according to patent 706 573, in which a drawing bench has two rolling machines are assigned, which are arranged on one side of the drawbench. The need for Arrangement of two rolling machines results from the fact that the rolling machine forms the narrowest cross-section of the system and the number of Pipes can only be processed with the help of two rolling machines if the capacity of the drawing benches is fully utilized shall be. The arrangement of two rolling machines of the usual type side by side has a very large space requirement Consequence, not for the mostly limited space in the pipe drawing Available. Gemäß der Erfindung wird dadurch Abhilfe geschaffen, daß zwei unabhängig voneinander arbeitende Schräg walzenpaare in einem gemeinsamen Gerüst nebeneinandergelagert sind, wobei die zusammenarbeitenden Walzen übereinanderliegen. Der Erfindungsgedanke besteht also nicht nur darin, zwei Abwalzmaschinen in einem Gerüst zu vereinigen, sondern weiterhin in der besonderen Anordnung der Walzenpaare, derart, daß die zusammenarbeitenden Walzen übereinandeiiiegen. Auf diese Weise erhält man neben einer Einsparung an Baustoffen der Maschine selbst und ihrer Bettung ein Höchstmaß an Raumersparnis in einer Art, wie sie in der Technik der Abwalzmaschinen als völlig neu und ungewohnlich angesehen werden muß. Außerdem erfährt die Förderung von der äußeren Abwälzmaschine zur Ziehbank eine Verkürzung.According to the invention, a remedy is provided that two are independent of one another working inclined roller pairs in one joint Scaffold are stored side by side, with the cooperating rollers lying on top of each other. The idea of the invention is not only to combine two rolling machines in one stand, but rather furthermore in the special arrangement of the roller pairs, such that the cooperating Rollers lie on top of one another. In this way one gets besides a saving maximum space savings in terms of building materials for the machine itself and its bedding in a way that is completely new and unusual in the technology of the rolling machines must be viewed. In addition, the conveyance learns from the external generating machine a shortening to the draw bench. Die Abbildung zeigt eine Ansicht des erfindungsgemäßen gemeinsamen Gerüstes 1 mit den übereinanderliegenden Schrägwalzenpaaren 2 und 3. Die Gerüstfenster werden zweckmäßig dvirch die abnehmbaren Kappen 4 und 5 abgeschlossen, um die Walzenpaare 2 und 3 bequem nach oben ausbauen zu können. Die Führung der abzuwälzenden Rohre 6 und 7 erfolgt, wie üblich, durch anstellbare Lineale 8 und 9. Die Walzenanstellung kann von unten z.B. durch Stellkeile 10 und 11, von oben durch Stellspindeln 12 und 13 erfolgen.The figure shows a view of the common frame 1 according to the invention the skewed roller pairs 2 and 3 lying one above the other. The frame windows are expediently dvirch the removable caps 4 and 5 completed in order to be able to easily expand the roller pairs 2 and 3 upwards. The pipes 6 and 7 to be rolled are guided, as usual, by adjustable rulers 8 and 9. The rollers can be adjusted from below, e.g. using adjusting wedges 10 and 11, from above by adjusting spindles 12 and 13. Der Walzenantrieb erfolgt in der bei Abwalzmaschinen üblichen bekannten Art, dessen Darstellung sich daher erübrigt.The roller drive takes place in the usual known manner in rolling machines, its Presentation is therefore unnecessary.
