Description

Rohrbogen und Verfahren zu seiner Herstellung Die Erfindung bezieht sich auf Rohrbögen und ein Verfahren zu ihrer Herstellung. Es handelt sich insbesondere um verhältnismäßig kurze Rohrbögen, die mit üblichen Biegeverfahren nicht herstellbar sind. Solche kurzen Rohrbögen werden beispielsweise in Rohrleitungen, wie Abgas- oder Verbrennungsluft-Zeitungen Kraftfahrzeugen gebraucht. Im Hinblick auf große Strömungs-Geschwindigkeiten wird gefordert, daß die Rohrbögen durch ihre Form keine Einschnürung der Strömung verursachen. Außerdem soll die Herstellung der Rohrbögen nicht zu aufwendig sein.Elbows and method for their manufacture The invention relates focus on elbows and a process for their manufacture. It is in particular relatively short pipe bends that cannot be produced using conventional bending processes are. Such short pipe bends are used, for example, in pipelines such as exhaust gas or combustion air newspapers used in motor vehicles. In terms of great Flow velocities are required that the pipe bends due to their shape no Cause constriction of the flow. In addition, the production of the pipe bends don't be too expensive.

Der Rohrbogen nach der Erfindung ist dadurch gekennzeichnet, daß das Rohr in Gestalt einer Kugelzone aufgeweitet, anschließend in einer zur Rohrachse geneigten Ebene durch die Kugelmitte zerschnitten und schließlich nach gegenseitiger Verdrehung der Teile wieder zusammengeschweißt ist. Die Kugelzone als Aufweitung des Rohres kann z.B. auf einfache Weise dadurch hergestellt werden, daß eine in das Rohr hineingesteckte Gummifüllung unter der Presse in eine Kugelform. gedrückt wird. Die aufzuweitende Stelle des Rohrs kann dabei in einer längs-geteilten Kugel-Hohlform liegen, mit der die Aufweitung begrenzt wird.The pipe bend according to the invention is characterized in that the Tube expanded in the shape of a spherical zone, then in one to the tube axis inclined plane cut through the center of the sphere and finally towards mutual Twisting of the parts is welded back together. The spherical zone as an expansion of the pipe can be produced in a simple manner, for example, by inserting an in the tube inserted rubber filling under the press into a spherical shape. pressed will. The point of the pipe to be widened can be in a longitudinally divided spherical hollow shape with which the expansion is limited.

Ein besonderer Vorzug des erfindungsgemäßen Rohrbogens ist darin begründet, daß in den vom Durchmesser-Verhältnis des Rohrs und der Kugelzone gegebenen Grenzen jeder beliebige Bogenwinkel herstellbar ist. Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht.A particular advantage of the pipe bend according to the invention is based on that within the limits given by the diameter ratio of the tube and the spherical zone any arc angle can be produced. The invention is in illustrated in the drawing, for example.

Abb. 1 zeigt ein Rohrstück mit Kugelzone vor dem Zerschneiden. In Abb. 2 ist ein fertiger Rohrbogen dargestellt.Fig. 1 shows a pipe section with a spherical zone before cutting. In Fig. 2 shows a finished pipe bend.

Das Rohrstück 1 nach Abb. 1 wurde an der Stelle des zu erzeugenden Bogens in Gestalt einer Kugelzone 2 aufgeweitet, beispielsweise durch Drücken eines in das Rohr eingeführten Gummifüllstükkes in eine Kugelform. In strichpunktierter Linie 3 ist die durch den Mittelpunkt 4 der Kugel geführte Ebene angedeutet, in der das Rohrstück nach der Aufweitung zerschnitten. wird. Die Schnittebene ist gegenüber der Rohrachse um einen Winkel 01. geneigt, der im vorliegenden Beispiel 60 0 beträgt.The pipe section 1 according to Fig. 1 was expanded at the point of the arc to be generated in the form of a spherical zone 2, for example by pressing a rubber filler inserted into the pipe into a spherical shape. In the dash-dotted line 3, the plane passed through the center point 4 of the sphere is indicated, in which the pipe section is cut after the expansion. will. The cutting plane is inclined with respect to the pipe axis by an angle, which in the present example is 60 °.

Nach Abb. 2 sind die Teile des Rohrstückes nach einer gegenseitigen Verdrehung in der Schnittebene 3 wieder zusammengeschweißt. Im vorliegenden Beispiel betragen die gegenseitige Verdrehung 180 o und der Bogenwinkel 2 OL= 120 0. Aua der Darstellung ist erkennbar, daß bei dem gegebenen Durchmesser-Verhältnis von Kugel zu Rohr und dem gewählten Schnittwinkel von 60 0 je nach Verdrehung der Rohrteile jeder beliebige Bogenwinkel zwischen 180 0 und 120 0 herstellbar ist.According to Fig. 2, the parts of the pipe section are welded together again after a mutual rotation in the section plane 3. In the present example, the mutual rotation is 180 o and the arc angle 2 OL = 120 0. From the illustration, it can be seen that with the given diameter ratio of ball to tube and the selected cutting angle of 60 0, depending on the rotation of the pipe parts, any arc angle between 180 0 and 120 0 can be produced.
