Abstract

The invention relates to a hose connection, comprising a rigid pipe of metal or plastic for connecting flexible hoses of natural, synthetic or special rubber with or without reinforcing strengtheners. The essential feature of this hose connection is that the end of the hose is pushed into the rigid pipe and that there is a bonding layer in the contact region between the outer face of the hose and the inner face of the pipe.

Description

Schlauchanschluß Hose connection

Die Erfindung bezieht sich auf einen Schlauchanschluß gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a hose connection according to the preamble of claim 1.

In vielen technischen Bereichen sind Schlauchanschlüsse erforderlich. Im einfachsten Fall besteht der Anschluß aus einem starren Rohr mit geradlinigem oder gekrümmtem Verlauf. Dabei wurde bisher der Schlauch auf das starre Rohr aufgeschoben. Die Befestigung des Schlauches erfolgte dann mit einer Schlauchschelle oder mit einer Klebmasse. Diese Form des Anschlusses ist nun aber mit einem bisher ungelösten Problem verbunden. Am Rohranfang wirken auf den Schlauch große Kräfte, die sich insbesondere bei Uber- oder Unterdruck des fluiden Mediums bemerkbar machen. Die Folge ist, daß der Schlauch an dieser Stelle raschen Verschleißerscheinungen (z. B. Rißbildung) unterliegt, so daß der Anschlußbereich nach Entfernen des verschlissenen Schlauchstückes durch Abschneiden häufig neu hergestellt werden muß.Hose connections are required in many technical areas. In the simplest case, the connection consists of a rigid pipe with a straight line or curved course. In the past, the hose was pushed onto the rigid pipe. The hose was then attached with a hose clamp or with an adhesive. However, this form of connection has not yet been resolved Problem connected. At the beginning of the pipe, great forces act on the hose make noticeable in particular in the case of overpressure or underpressure of the fluid medium. the The result is that the hose shows rapid signs of wear at this point (e. B. cracking), so that the connection area after removing the worn Tube piece often has to be made anew by cutting.

Auch die rasche Ablösung des Schlauches vom Rohr bei Überdruck ist möglich, da im Randbereich unendlich große Kräfte herrschen.There is also the rapid detachment of the hose from the pipe in the event of overpressure possible because there are infinitely great forces in the edge area.

Aufgabe der Erfindung ist es daher, den Anschlußbereich so zu gestalten, daß der Schlauch verschleißfest und sicher mit dem starren Rohr verbunden ist.The object of the invention is therefore to design the connection area so that the hose is wear-resistant and securely connected to the rigid pipe.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß das Ende des Schlauches in das starre Rohr eingeschoben ist und sich im Kontaktbereich zwischen der Außenfläche des Schlauches und der Innenfläche des Rohres eine Haftschicht befindet.The solution to this problem is that the end of the hose is pushed into the rigid tube and is in the contact area between there is an adhesive layer on the outer surface of the hose and the inner surface of the pipe.

Durch das Einschieben des Schlauchendes in das Rohr ist gewährleistet, daß sich die auftretenden Kräfte im Gegensatz zur ursprünglichen Anschlußform auf die gesamte Kontaktfläche verteilen.Pushing the end of the hose into the pipe ensures that that the forces that occur are in contrast to the original connection shape distribute the entire contact area.

Eine sichere Haftung zwischen Schlauch und Rohr wird dadurch erreicht, daß der noch vulkanisierbare oder bereits vulkanisierte Schlauch im Kontaktbereich mit einer vulkanisierbaren Schicht (Kautschukmischung, Kleber oder Lösung) versehen ist und nach dem Einschieben in das Rohr durch eine Vulkanisation, wobei verschiedene Bedingungen möglich sind, nachbehandelt wird.A secure adhesion between hose and pipe is achieved by that the hose that is still vulcanizable or has already been vulcanized is in the contact area provided with a vulcanizable layer (rubber mixture, adhesive or solution) is and after being pushed into the tube by vulcanization, with various Conditions are possible, is post-treated.

Das Rohr kann aus Kunststoff bestehen, der auch bei auftretender Vulkanisationstemperatur formbeständig ist.The tube can be made of plastic, which also when the vulcanization temperature occurs is dimensionally stable.

Die Temperaturbeständigkeit kann durch Verwendung von Füllstoffen erhöht werden. In vielen Fällen ist ein Rohrstück aus Polyamid 66 ausreichend.The temperature resistance can be achieved through the use of fillers increase. In many cases, a piece of pipe made of polyamide 66 is sufficient.

Die Haftung zwischen Schlauch und Rohr kann auch durch Kaltklebung erfolgen. Um bei der Herstellung des Schlauchanschlusses eine besonders gute Verklammerung zu erhalten, kann das Rohr im Verbindungsbereich innere Ringrippen aufweisen.The adhesion between hose and pipe can also be achieved by cold bonding take place. In order to achieve particularly good clamping when making the hose connection To obtain, the tube can have inner annular ribs in the connection area.

Das hier beschriebene Verbinden eines Schlauches mit einem starren Rohr kann auch dazu verwendet werden, T-Schläuche herzustellen. Anstelle eines einfachen Rohres wird dann lediglich ein T-förmiges Rohrverzweigungsstück eingesetzt.The connection of a hose with a rigid one as described here Pipe can also be used to make T-hoses. Instead of a simple one Pipe is then only used a T-shaped pipe branching piece.

Die Erfindung wird in Verbindung mit den Abbildungen 1 und 2 beschrieben. Während die Abb. 1 den bisherigen Schlauchanschluß zeigt, wird in Abb. 2 der erfindungsgemäße Anschluß dargestellt.The invention is described in connection with FIGS. 1 and 2. While Fig. 1 shows the previous hose connection, Fig. 2 shows the inventive Connection shown.

Nach Abb. 1 ist ein elastischer Schlauch 1 auf ein starres Rohr 2 aus Metall oder Kunststoff geschoben.According to Fig. 1, an elastic hose 1 is on a rigid tube 2 made of metal or plastic.

Dadurch daß am Rohranfang in Position 3 bei Über- oder Unterdruck große Kräfte unverteilt auf den Schlauch einwirken, bleiben rasche Verschleißerscheinungen im Anschlußbereich des Schlauches nicht aus. Auch löst sich bei Überdruck der Schlauch zu leicht vom Rohr, da im Randbereich unendlich große Kräfte herrschen.Because of the fact that at the beginning of the pipe in position 3 with overpressure or underpressure If large forces act on the hose in an undistributed manner, signs of wear remain quickly in the connection area of the hose. The hose will also come loose if there is overpressure too easy from the pipe, as there are infinitely great forces in the edge area.

Nach Abb. 2 ist ein elastischer Schlauch 4 in ein starres Rohr 5 aus Metall oder Kunststoff eingeschoben. Zwischen dem Schlauch und dem Rohr 5 befindet sich eine Haftschicht 6 aus vulkanisierbarem Material (Kautschukmischung, Kleber oder Lösung) oder aus einem Kaltkleber. Die im Schlauch 4 auftretenden Kräfte bei Überdruck verteilen sich auf den gesamten Kontaktbereich zwischen Schlauch und Rohr.According to Fig. 2, an elastic hose 4 is made in a rigid tube 5 Metal or plastic inserted. Located between the hose and the tube 5 An adhesive layer 6 made of vulcanizable material (rubber mixture, adhesive or solution) or from a cold glue. The forces occurring in the hose 4 at Overpressure is distributed over the entire contact area between hose and pipe.
