Description

den Ring anzuschweißen. Mittels einer Schraubenzwinge, die an den angeschweißten Stegen zum Eingriff gebracht wird, kann der Ring somit vor seiner - Verschweißung -fest - zusammengespannt werden. Das Verschweißen' des Rings kann im Autogenverfahren oder auch durch elektrische Lichtbogen-:ichweißung erfolgen. Am vorteilhaftesten wird hier jeldoch die Gleichstromlichtbogenschweißung angewandt, weil durch die Anwendung des Kohlelichtbogens der angewärmte Ring weiter noch zusätzlich ,nachgewärmt werden kann. weld the ring on. By means of a screw clamp, which is brought into engagement with the welded webs, the ring can thus be clamped together before it is welded. The ring can be welded using the oxy-fuel process or by electric arc welding. However, it is most advantageous to use direct current arc welding because the use of the carbon arc allows the heated ring to be additionally reheated.

:In den Abbildungen ist ein Ausführungsbeispiel des Erfindungsgegenstands dargestellt.' In Abb. i ist -der Zylinder i eines Hebetisches für ein Walzwerk mit den doppelseitigen Flanschen! 2 und 3 und den aufgebrachten Schrumpfringen 4 und 5 nach Vollendung der Schweißung an den Schrumpfringen ersichtlich. Mit io ist die Schweißstelle am Zylinder, die vor dem Aufziehen der Schrumpfringe 4 und 5 geschweißt ist, angedeutet.: In the figures is an embodiment of the subject matter of the invention shown. ' In Fig. I - the cylinder i is a lifting table for a rolling mill with the double-sided flanges! 2 and 3 and the applied shrink rings 4 and 5 can be seen on the shrink rings after welding has been completed. With io is the Welding point on the cylinder, which was welded before pulling on the shrink rings 4 and 5 is indicated.

Abb. 2 zeigt einen Ausschnitt eines solchen gebogenen- Schrumpfrings mit den aufgeschweißten Stegen 6 und 7. Diese Stege werden an der Stelle 8 und 9, also an den Außenseiten gegenüber der Stoßstelle i i, an den Schrumpfring senkrecht zu diesem angeschweißt; damit sie dem kräftigen Druck der Schraubenzwinge standhalten. Nach dem Verschweißen -des Schrumpfrings können sie durch leichten Hammerschlag auf die Innenseite in Richtung der Außenseite leicht wieder abgeschlagen werden.Fig. 2 shows a section of such a curved shrink ring with the welded-on webs 6 and 7. These webs are at the point 8 and 9, so on the outside opposite the joint i i, perpendicular to the shrink ring welded to this; so that they can withstand the strong pressure of the screw clamp. After welding the shrink ring, you can remove it with a light hammer blow can be easily knocked off again on the inside towards the outside.
