Description
Befestigung von-Rohteln""äurch Spannringe Es ist bekannt, daß beim Einwalzen von Rohren in Fällten, wo eine Dichtheit der Walzstelle trotz starken Einwalzens nicht errecht werden kann, Spannringe zusätzlich eingewalzt werden. Es ist bekannt, daß derartige Spannringe die Dichtheit der Walzstellen erhöhen. Solche Spannringe wurden bisher in verschiedenen Formen ausgeführt.Fastening of tubes "" by means of clamping rings It is known that when Rolling of pipes in falls, where a tightness of the rolling point despite strong Rolling in cannot be achieved, clamping rings are additionally rolled in. It it is known that such clamping rings increase the tightness of the rolling points. Such Tension rings have so far been designed in various forms.
Der neue Spannring unterscheidet sich von den bekannten dadurch, daß er sich nur auf .den versenkt eingewalzten Bördelteil des Rohres erstreckt. Hierdurch erhält das Rohr seine größte Einspannung in der Nähe des inneren Lochrandes. Die in den Rohren auftretenden Bieggungsspannungen werden durch den davorliegenden Teil der Walzstelle aufgenommen. Die Einspannung des Rohres ist bei Anwendung des neuen Spannringes hinsichtlich des Auftretens von Rundrissen in der Einwalzstelle günstiger.The new clamping ring differs from the known ones in that it extends only to the sunk rolled-in flanged part of the tube. Through this the pipe receives its greatest restraint near the inner edge of the hole. the Bending stresses occurring in the pipes are caused by the part in front of it added to the rolling point. The clamping of the pipe is when using the new one The clamping ring is more favorable with regard to the occurrence of round cracks in the rolling-in point.
Es wurde gefunden, daß die Abdichtung der Walzstelle nicht von ihrer Einwalzlänge abhängt, sondern von der Pressung zwischen Rohr und Loch, und daß ;ein kurzer ringförmiger Teil der Walzstelle, in welchem eine höhere Pressung zwischen Rohr und Loch vorhanden ist, zur Abdichtung genügt. Der Fortschritt des Spannringes gemäß der Erfindung beruht darin, daß die Abdichtung an der Stelle vorgenommen wird, wo eine etwaige Urdichtheit ihnen Anfang nehmen würde. Ferner wird die Abdichtungsstelle nicht durch Biegungskräfte belastet, die eine wesentliche Ursache von Undichtheiten sind. Die Abdichtungsstelle kanndaher mit besonders hoher Verspannung ausgeführt werden, ohne daß .die Gefahr eines Dauerbruches, wie sie sich vielfach bei ;anderen Abdichtu gsstellen auswirkte, eintreten kann.It was found that the sealing of the rolling point does not depend on their Roll-in length depends, but on the pressure between tube and hole, and that; a short annular part of the rolling point in which a higher pressure between Pipe and hole are present, sufficient for sealing. The progress of the tension ring according to the invention is based on the fact that the seal is made at the point where a possible primordial density would begin for them. Furthermore, the sealing point not burdened by bending forces, which are a major cause of leaks are. The sealing point can therefore be designed with a particularly high level of tension without the risk of fatigue failure, as is often the case with others Sealing points can occur.
Im der Zeichnung ist die Ausbildung des neuen Spannringes dargestellt. i ist darin die Platte oder Trommel mit der Bohrung für das Einwalzen des Rohres 2. Diese Bohrung ist bei 3 am offenen Ende des Rohres zylindrisch erweitert, wobei die Erweiterung auf die eigentliche Bohrung am besten kegelig, q., übergeht. Das Rohr kann im nicht erweiterten Teil :dies Rohrloches auf der ganzen Länge oder nur auf einen Teil angewalzt werden. Im erweiterten Teil ist der Sprengring oder Spannring 5 in bekannter Weise nach dem Einwalzen des Rohres neingewalzt.The drawing shows the design of the new clamping ring. i is the plate or drum with the hole for rolling in the pipe 2. This bore is expanded cylindrically at 3 at the open end of the tube, wherein the extension to the actual bore is best tapered, q., merges. That Pipe can be in the non-extended part: this pipe hole along the entire length or only be rolled onto a part. In the extended part is the snap ring or clamping ring 5 re-rolled in a known manner after the pipe has been rolled in.
