Abstract

The joint flange (1) is made of a relatively thick disc (5) from which a tubular extension (3) is formed by deep drawing. The extension (3) is then butt-welded to the end of the pipe. An annular groove (6) of rectangular cross-section is machined in the face of the flange (5). A second similar flange is provided with a circular projection (7) which matches the groove (6). A sealing ring is fitted in the groove (6) and the pair of flanges are clamped together by a pair of rings (4).

Description

Bundbördel. Collar.

Die Neuerung betrifft einen Bundbördel, bestehend aus einer metallischen Ringscheibe, deren Innenrand durch Tiefziehen zu einem Zylinderbund ausgehalst ist. The innovation concerns a collar, consisting of a metallic one A ring disc, the inner edge of which is cut into a cylinder collar by deep drawing.

Bei Rohrverbindungen wird häufig eine Nut- und Federanordnung auf der Dichtfläche der miteinander zu verbindenden Rohrteile gefordert, um eine gute und sichere Abdichtung an der Verbindungsstelle zu erreichen. Hierzu werden in bekannter Weise verhältnismäßig schwere geschmiedete oder gewalzte Bunde verwendet, wobei in den einen Bund eine ringförmige Feder und in den gegenüberliegenden eine Ringnut eingearbeitet wird. A tongue and groove arrangement is often used for pipe connections the sealing surface of the pipe parts to be connected to one another is required to achieve a good and to achieve a secure seal at the joint. For this purpose are known in Way relatively heavy forged or rolled collars are used, whereby in one collar an annular spring and in the opposite one an annular groove is incorporated.

Ziel der vorliegenden Erfindung ist nun eine Verbilligung der Herstellung solcher Bunde, und zwar einmal durch Materialersparnis und zum anderen durch einfachere Fertigung. The aim of the present invention is to make production cheaper such bundles, on the one hand through material savings and on the other hand through simpler ones Production.

Hierzu wird neuerungsgemäß ein Bundbördel der eingangs genannten Art vorgeschlagen, der dadurch gekennzeichnet ist, daß in die Dichtfläche des aus verhältnismäßig dickem Blech hergestellten Bundbördels durch mechanische Bearbeitung, vorzugsweise Drehen, eine Nut bzw. Feder jeweils in Ringform ein- bzw. herausgearbeitet ist. Gemäß einer vorteilhaften Ausgestaltung des neuerungsgemäßen Bundbördels kann sein zylindrischer Abschnitt mechanisch, vorzugsweise durch Drehen, auf Rohranschlußmaß bearbeitet sein.For this purpose, according to the innovation, a collar of the type mentioned at the beginning proposed, which is characterized in that in the sealing surface of the relatively thick sheet metal flange made by mechanical processing, preferably Turn, a tongue or groove is worked in or out in each case in a ring shape. According to an advantageous embodiment of the flange according to the innovation can be Cylindrical section mechanically, preferably by turning, to pipe connection dimensions be processed.

In der Zeichnung ist ein Ausführungsbeispiel des neuerungsgemäßen Bundbördels dargestellt.In the drawing is an embodiment of the innovation according to the invention Bundle shown.

Fig. 1 zeigt einen Längsschnitt und Fig. 2 eine Draufsicht des neuerungsgemäßen Bundbördels.Fig. 1 shows a longitudinal section and Fig. 2 shows a plan view of the innovation according to the invention Collar.

Der neuerungsgemäße Bundbördel 1 wird zunächst in Form einer verhältnismäßig dicken Ringscheibe 2 hergestellt, aus der in bekannter Weise dann der zylindrische Abschnitt 3 tiefgezogen wird, an den das Rohr angeschweißt wird.The innovation according to the flange 1 is initially in the form of a proportionate thick washer 2 made from which in a known manner then the cylindrical Section 3 is deep-drawn, to which the pipe is welded.

In die Dichtfläche 5 des Bundbördels 1 wird dann neuerungsgemäß in dem einen Fall die Ringnut 6 mechanisch eingearbeitet und im Falle des gegenüberliegenden Bundbördels die ringförmige Feder 7, wobei im linken Teil der Figur 1 durch die strichpunktierte Linie 8 die ursprüngliche Kontur des Bördels vor dem Heraus arbeiten der Ringfeder 7 angedeutet ist.In the sealing surface 5 of the flange 1 is then renewed according to in the one case, the annular groove 6 mechanically incorporated and in the case of the opposite The collar flange, the annular spring 7, wherein in the left part of Figure 1 by the Dotted line 8 work the original contour of the flange before working out the ring spring 7 is indicated.

Beim Zusammenbau der Rohrverbindung wird in die Ringnut 6 des einen der beiden gegenüberliegenden Bundbördel die Dichtung oder Packung eingelegt und der gegenüberliegende Bundbördel 1 mit der Ringfeder 7 in die Ringnut 6 hineingedrückt. Mittels Fest- oder Überwurfflanschen 4 kann dann die dichtende Rohrverbindung mittels der neuerungsgemäßen Bundbördel hergestellt werden.When assembling the pipe connection is in the annular groove 6 of the one of the two opposite flanges the seal or pack inserted and the opposite collar 1 with the annular spring 7 in the annular groove 6 pressed in. By means of fixed or coupling flanges 4, the sealing Pipe connection can be produced by means of the flange flange according to the innovation.

Durch mechanische Bearbeitung, vorzugsweise Drehen, kann auch der zylindrische Abschnitt 3, falls erforderlich, auf Rohranschlußmaß gebracht werden, was in einem Arbeitsgang mit der Herstellung der Nut 6 bzw. Feder 7 erfolgen kann.By machining, preferably turning, the cylindrical section 3, if necessary, can be brought to pipe connection dimensions, which can be done in one operation with the production of the groove 6 or tongue 7.

Auf diese Weise läßt sich der neuerungsgemäße Bundbördel einfach und bei verhältnismäßig geringem Materialeinsatz auch preiswert herstellen,In this way, the flange according to the innovation can be easily and can also be produced inexpensively with relatively little use of material,
