Description

Schlaucharmatur für Hochdruckschläuche Die Erfindung betrifft eine Endarmatur für Schläuche, die Medien unter hohem Druck führen. Diese Endarmaturen dienen zum Ankuppeln der Schläuche und bestehen aus einer das Schlauchende außen umfassenden Hülse und einem in den Schlauch eingeführten Nippel, wobei die ursprünglich kreiszylindrische Hülse nach eingebrachtem Schlauchende und Nippel verbleibend nach innen dergestalt verformt wird, daß sie in benachbarten Radialebenen wellenförmig zusamengepreßt ist, wobei die ringsum laufenden Rillen zum Schlauchende hin größere Durchmesser aufweisen.Hose fitting for high pressure hoses The invention relates to a End fitting for hoses that carry media under high pressure. These end fittings are used to couple the hoses and consist of one end of the hose on the outside comprehensive sleeve and a nipple inserted into the hose, the originally circular cylindrical sleeve after inserted hose end and nipple remaining after is deformed inside in such a way that it is undulating in adjacent radial planes is pressed together, the circumferential grooves being larger towards the end of the hose Have diameter.

Es hat sich gezeigt, daß diese Ausbildung der Verformung im Zusammenwirken mit einer besonderen Gestaltung der Mantelfläche des Nippels im Bereich der stärksten Verformung der Hülse vorteilhaft verbessert werden kann.It has been shown that this formation of the deformation in cooperation with a special design of the outer surface of the nipple in the area of the strongest Deformation of the sleeve can be improved advantageously.

Erfindungsgemäß wird hierzu vorgeschlagen, im Bereich der stärksten Zusammenpressung der Hülse die Mantelfläche des Nippels mit ebenfalls in Radialebenen umlaufenden Rillen mit sägezahnartigem Querschnitt zu versehen, wobei die steile Flanke dieser Rillen zu der vom Schlauchende abgewandten Seite des Nippels gerichtet ist.According to the invention it is proposed for this purpose in the area of the strongest Compression of the sleeve with the outer surface of the nipple also in radial planes to provide circumferential grooves with a sawtooth-like cross-section, the steep Flank of these grooves directed towards the side of the nipple facing away from the hose end is.

Es ist zwar an sich schon bekannt, am Nippel derartige Rillen vorzusehen, dort sind jedoch die steilen Flanken dem Schlauchende zugerichtet. Bei Zugwirkung auf den Schlauch besteht hier während des Betriebes die Gefahr der Verletzung der Innenwandung des Schlauches. Es sollte wohl erreicht werden, daß die Zähne ein Abgleiten des Schlauchendes vom Nippel verhindern.It is known per se to provide such grooves on the nipple, there, however, the steep flanks are trimmed to the end of the hose. When pulling there is a risk of injury to the hose during operation Inner wall of the hose. It should be achieved that the teeth slide off the end of the hose from the nipple.

Es hat sich nun gezeigt, daß bei der erfindungsgemäßen Ausbildung der Armatur die Rillen mit sägezahnartigem Querschnitt diese Aufgabe nicht zu erfüllen brauchen, da durch die Verformung der Hülse das Schlauchende in der Armatur bereits in genügender Weise festgelegt ist. Die Rillen mit sägezahnartigem Querschnitt haben erfindungsgemäß demgegenüber die Aufgabe, zusammen mit den in diesen Rillen eingepreßten Bereichen des Schlauches dichtend zu wirken. Unter dem Druck des in der Schlauchleitung geführten Mediums legt sich das Material des Schlauches jeweils an die steilen Flanken der sägezahnartigen Rillen an.It has now been shown that in the training according to the invention of the valve, the grooves with a sawtooth-like cross-section do not fulfill this task need, because the deformation of the sleeve means that the end of the hose is already in the fitting is specified in a sufficient manner. The grooves have a sawtooth-like cross-section according to the invention, on the other hand, the task together with the grooves pressed into these grooves Areas of the hose to act as a seal. Under the pressure of the in the hose line guided medium, the material of the hose lies against the steep flanks the sawtooth-like grooves.

Die Erfindung ist in der nachfolgenden Beschreibung einer in der Zeichnung dargestellten beispielsweisen Ausbildungsform einer Schlaucharmatur näher erläutert.The invention is in the following description one in the drawing illustrated exemplary embodiment of a hose fitting explained in more detail.

F i g. 1 zeigt die Armatur in einem Zwischenstadium der Montage, nämlich vor Aufbringen der Rillen auf die Hülse, und zwar im Schnitt; in F i g. 2 ist derselbe Schnitt nach verformter Hülse, wiederum im Schnitt, dargestellt; die F i g. 3 entspricht der F i g. 2, gibt jedoch eine Seitenansicht der Armatur wieder.F i g. 1 shows the fitting in an intermediate stage of assembly, namely before making the grooves on the sleeve, in section; in Fig. 2 is the same Section after the deformed sleeve, again in section, shown; the F i g. 3 corresponds the F i g. 2, however, shows a side view of the fitting.

Auf das Ende des Schlauches 1 ist eine Hülse 2 aufgeschoben, welche kreiszylindrisch ausgebildet ist und das Schlauchende ringsum umfaßt. Weiterhin ist in die Hülse ein Nippel 3 eingeschraubt. Die Maße des Nippels 3 sind so ausgelegt, daß der Schlauch bei Einbringen desselben nicht allzusehr aufgeweitet wird.A sleeve 2 is pushed onto the end of the hose 1, which Is circular cylindrical and includes the hose end all around. Farther a nipple 3 is screwed into the sleeve. The dimensions of the nipple 3 are designed so that the hose is not widened too much when it is introduced.

Zur Fertigstellung der Armaturenmontage wird nun die Hülse 2 mit einem Spezialwerkzeug zusammengepreßt, so daß sie eine bleibende Verformung erhält, und zwar in Gestalt von in Radialebenen umlaufenden Rillen 5. Der Durchmesser dieser Rillen steigt dabei zum Schlauchende hin an, d. h., die Grundform der Hülse ist dann konisch.To complete the fitting assembly is now the sleeve 2 with a Special tool pressed together so that it receives a permanent deformation, and although in the form of circumferential grooves 5 in radial planes. The diameter of these Grooves rise towards the end of the hose, d. i.e., the basic shape of the sleeve then conical.

Im Bereich der Rillen 5 in der Hülse 2 sind in der Mantelfläche des Nippels 3 sägezahnartige Rillen 4 vorgesehen. Diese erstrecken sich in dem Bereich der stärksten Verformung der Hülse 2. Die Sägezähne 4 zeigen mit ihrer steilen Flanke in die vom Schlauchende abgewandte Richtung.In the area of the grooves 5 in the sleeve 2, sawtooth-like grooves 4 are provided in the outer surface of the nipple 3. These extend in the area of the greatest deformation of the sleeve 2. The saw teeth 4 point with their steep flank in the direction facing away from the hose end.

Das Vorhandensein dieser Zähne macht klar, daß der Nippel bei Einbringen in das Schlauchende letzteres nicht allzusehr aufweiten darf, da sonst die Gefahr einer Verletzung der Innenwandung des Schlauches bestehen würde.The presence of these teeth makes it clear that the nipple is being inserted the latter must not widen too much in the end of the hose, otherwise there is a risk an injury to the inner wall of the hose would exist.
