Die Erfindung bezieht sich auf ein Verfahren zurr. Herstellen einer T-förmigen Gummischlauchverzweigung mit Gewebeverstärkungseinlagen gemäß dem Gattungsbegriff des vorstehenden Patentanspruchs 1.The invention relates to a method zurr. Manufacture of a T-shaped rubber hose branch with fabric reinforcement inserts according to Generic term of the preceding claim 1.

In vielen technischen Bereichen, insbesondere im Kraftfahrzeugbau, sind Abzweigungen von Schläuchen für verschiedene Zwecke erforderlich. Um diesem Bedarf Rechnung zu tragen, wurden die Schläuche bisher mittels T-förmiger Metallrohrteile verbunden. Die Verbindung zwischen diesen und dem Schlauch erfordert eine genaue lichte Weite des Schlauches und eine Befestigung mittels Schlauchschellen. Derartige Schlauchschellen haben sich aber insbesondere dort, wo ständig Erschütterungen und Temperaturschwankungen auftreten, als nicht ausreichend sicher erwiesen. Mangels brauchbarer T-förmiger Gummischlauchverzweigungen mußte dieser Nachteil bisher jedoch in Kauf genommen werden.In many technical areas, especially in motor vehicle construction, there are branches of hoses required for various purposes. In order to meet this need, the hoses were previously connected by means of T-shaped metal pipe parts. The connection between these and the hose requires an exact inside width of the hose and an attachment by means of hose clamps. Such hose clamps but have proven particularly in places where there are constant vibrations and temperature fluctuations, proved to be insufficiently safe. In the absence of usable T-shaped rubber hose branches However, this disadvantage had to be accepted up to now.

Es ist ein Verfahren zum Herstellen einer T-förmigen 6S Gummischlauchverzweigung mit Gewebeverstärkungseinlagen bekannt, bei dem in der Wand eines Schlauches eine Wandöffnung gebildet, deren Rand bearbeitet zusätzliches Material an dem Rand der Wandöffnung angebracht und ein Abzweigschlauch in die Wandöffnung eingesetzt wird und die Ränder der Wandöffnung und des Abzwcigschlauches durch Vulkanisation miteinander verbunden werden.A method for producing a T-shaped 6 S rubber hose branch with fabric reinforcement inserts is known in which a wall opening is formed in the wall of a hose, the edge of which is machined, additional material is attached to the edge of the wall opening and a branch hose is inserted into the wall opening and the edges the wall opening and the branch hose are connected to one another by vulcanization.

Bei diesem Verfahren werden die Verbindungsflächen der beiden Schlauchteile mit einer Ansenkung versehen und es wird eine Kautschukhaftmischung zwischen diese Verbindungsflächen gebracht und vulkanisiert. Je nach Kautschukmischungsaufbau der Schläuche kann das Einvulkanisieren einer Haftmischung zwischen den fertig vulkanisierten Schlauchteilen mit verschiedenen Schwierigkeiten verbunden sein. Insbesondere bei dünnwandigen Schläuchen läßt sich eine solche Verbindung nur schwer mit ausreichender Haftsicherheit erstellen. Die vollständige Abdeckung der an den Schlauchverbindungsstellen austretenden Gewebeverstärkungseinlagen erfordert außerdem einen ständig und sorgfältig überwachten Herstellungsvorgang. Nachteilig ist ferner, daß gerade in der Verbindungsschicht die Gewebeverstärkungseinlage unterbrochen In this process, the connecting surfaces of the two hose parts are provided with a countersink and an adhesive rubber mixture is placed between these connecting surfaces and vulcanized. Depending on the rubber compound structure of the hoses, vulcanizing an adhesive compound between the fully vulcanized hose parts can be associated with various difficulties. In particular in the case of thin-walled hoses, such a connection can only be made with sufficient adhesive security with difficulty. The complete covering of the fabric reinforcement inserts emerging at the hose connection points also requires a constantly and carefully monitored manufacturing process. Another disadvantage is that the fabric reinforcement insert is interrupted precisely in the connecting layer

Aufgabe der Erfindung ist es. ein Verfahren zum Herstellen einer T-förmigen Gummischlauchverzweigung, wie sie eingangs umrissen worden ist, /u schaffen, bei dem unter Vermeidung der obengenannt Nachteile m der Verbindungsstelle der Schlauchk-ile eine hohe Festigkeit erhalten wird, ohne daß die Herstellung eine über das übliche hinausgehende Sorgfall erfordert. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst werden, daß das Bilden der Wandöffnung in einem noch vulkanisierbaren Rohling eines Schlauches erfolgt, der Rand der Wandöffnung beim Bearbeiten nach außen gebördelt, zum Anbringen des zusätzlichen Materials ein trichterförmiges vulkanisiertes Gummischlauchstück unter den gebördelten Rand der Wandöffnung geklebt und der Rand des ebenfalls noch vulkanisierbaren Rohlings des Abzweigschlauches vor dessen Einsetzen in die Wandöffnung gleichfalls nach außen gebördelt wird und die Verbindung der überlappten Ränder der Wandöffnung und des Abzweigschlauches unter gleichzeitiger Vulkanisation des Kautschuks des Schlauchrohlings und des Abzweigschlauchrohlings erfolgt.It is the object of the invention. a method of making a T-shaped rubber hose branch, as outlined at the beginning, / u create while avoiding the disadvantages mentioned above m the connection point of the hose cable high strength is obtained without the manufacture requiring excessive care. This object is achieved according to the invention in that the formation of the wall opening takes place in a still vulcanizable blank of a hose, the edge of the wall opening during processing crimped outwards, a funnel-shaped vulcanized one to attach the additional material Rubber hose stuck under the beaded edge of the wall opening and the edge of the wall too vulcanizable blank of the branch hose before it is inserted into the wall opening is crimped on the outside and the connection of the overlapped edges of the wall opening and the branch hose with simultaneous vulcanization of the rubber of the hose blank and the branch hose blank he follows.

Die Verpressung erfolgt unter gleichzeitiger Vulkanisation auf einfache Weise und erfordert keine über das übliche hinausgehende Sorgfalt bei einer betrieblichen Ausführung. Der Arbeitsablauf ist dabei kaum störanfällig. Das trichterförmige Gummischlauchstück und die Bördelungsränder der aufeinandergesteckten Schlauchteile lassen sich sicher verbinden.The pressing takes place with simultaneous vulcanization in a simple way and does not require any care beyond the usual care of an operational Execution. The workflow is hardly prone to failure. The funnel-shaped piece of rubber hose and the flanged edges of the hose parts that are pushed one on top of the other can be securely connected.

Da auch die Gewebeverstärkungseinlagen zur Überlappung kommen, ist die Druckfestigkeit im T-Bereich besonders groß. Bei übermäßiger Beanspruchung platzt die Gummischlauchverzweigung nur außerhalb dieses Bereiches. Das trichterförmige Gummischlauchstück ist auf die Kautschukmischung der Schlauchrohlingsteile abgestimmt. Ist diese auf Polychlorbutadien-Basis aufgebaut, so ist das trichterförmige Gummischlauchstück in gleicher Weise aufgebaut. Da vor der Vulkanisation beim Unterlegen des trichterförmigen Gummischlauchstücks eine Verklebung erfolgt, ist auch dies beim Mischungsaufbau zu berücksichtigen.Since the fabric reinforcement inserts also overlap, the compressive strength is in the T area extraordinary big. In the event of excessive stress, the rubber hose branch only bursts outside of this Area. The funnel-shaped rubber hose piece is on the rubber mixture of the hose blank parts Voted. If this is based on polychlorobutadiene, the funnel-shaped piece of rubber hose is constructed in the same way. Since before vulcanization When the funnel-shaped piece of rubber hose is glued underneath, this is also when the mixture is built up to consider.

Als Gewebeverstärkungseinlage kann ein Gestrick aus Polyamid oder ähnlichen synthetischen oder halbsynthetischen Fasern, wie Reyon, verwendet werden.A knitted fabric made of polyamide or similar synthetic or semi-synthetic can be used as a reinforcement insert Fibers such as rayon can be used.

Formhohlraum aufweisenden, in einer Axialebene des Schlauches in zwei Schalenteile geteilten Muffe und einem Dorn mit einem im wesentlichen zylindrischen Querbalken, an den ein Stegbalken ansetzbar ibt. Die Vorrichtung zeichnet sich erfindungsgemäß dadurch s aus. daß die Teilung zwischen dem Querbalken unci dem Stegbalken des Dorr.es in der Überlappungszone des Randes der Wandöffnung des Schlauches und des Randes des Abzweigschlauches liegt.Mold cavity having, in an axial plane of the hose divided into two shell parts sleeve and a mandrel with a substantially cylindrical transverse beam to which a web beam can be attached. According to the invention, the device is characterized by s . that the division between the crossbar and the web bar of the Dorr.es lies in the overlap zone of the edge of the wall opening of the hose and the edge of the branch hose.

Vorteilhafterweise ist der Stegbalke.i mit einem Zap- ίο fen in eine Aussparung des Querbalkens einsetzbar.The Stegbalke.i is advantageously with a Zap- ίο fen can be used in a recess in the crossbeam.

Die Erfindung wird in Verbindung mit einer Abbildung beschrieben. Diese zeigt einen Querschnitt durch die T-förmige Zone der Gummischlauchverzweigung, durch Jen darin befindlichen Dorn und durch die umgreifende Muffe.The invention will be described in connection with an illustration. This shows a cross section through the T-shaped zone of the rubber hose branch, through Jen's mandrel and through the encompassing one Sleeve.

Nach der Abbildung ist ein mit einer Gewebeverstärkungseinlage verstärkter Rohling eines Schlauches 1 mit einer annähernd runden Öffnung versehen. Die Ränder 2 dieser öffnung werden nach außen aufgebördett. Der Schlauch 1 sitzt dabei auf einem Querbaiken 3 eines Dornes auf. Zwischen dem Querbalken 3 und dem Schlauch 1 ist ein trichterförmiges Gummischlauchstück 4 eingelegt, das die Teilung 5 mit einem Stegbalken 6 des Dornes um einiges überlappt. Dieses Gummischlauchstück 4 ist an seiner Oberfläche mit Klebstoff versehen, so daß es eine Verbindung zwischen dem Schlauch 1 und einem aufgesetzten Rohling eines Abzweigschlauches 7 herstellt. Dieser Abzweigschlauch 7 ist ebenfalls an den Rändern 8 aufgebördeh. Die aufgebördelten Ränder 8 und 2 überlappen sich und sind gleichzeitig durch das trichterförmige Gummischlauehsiück 4 über die volle Überlappungszone unter Verklebung unterleg'. Der Stegbalken 6 greift mittels eines Zapfens 9 in den Querbalken 3 ein, um eine feste Lage zu schaffen, so daß während der Vulkanisation Verschiebungen durch eine umgelegte Muffe nicht eintreten können. Diese Muffe besteht aus einem etwa trichterförmigen Teil 10. Dieses Teil 10 umgreift den Schlauch I auf beiden Seiten bis in eine Zone 11. Ein weiteres Schalenteil 12 umgreift die Vorder- und Rückseite des Schlauches 1 im unteren Bereich. Das Sch?.-lenteii 12 ist in der Zone Π mit dem trichterförmigen Teil 10 verbunden. Sie werden mittels einer Klemmvorrichtung zusammengehalten, so daß eine Vulkanisation unter gleichzeitiger Formgebung erfolgen kann. Der Querbalken 3 kann in der Mitte winklig geknickt sein. Ferner kann auch der Stegbalken 6 schiefwinklig angesetzt sein. Dadurch sind T-förmige Gummischlauchverzweigungen in vielen Gestaltungen möglich.After the picture is one with a fabric reinforcement insert Reinforced blank of a hose 1 is provided with an approximately round opening. the Edges 2 of this opening are flanged outwards. The hose 1 is seated on a crossbeam 3 of a thorn. Between the crossbar 3 and the hose 1 is a funnel-shaped piece of rubber hose 4 inserted, which overlaps the division 5 with a web bar 6 of the mandrel to some extent. This piece of rubber tubing 4 is provided with glue on its surface so that there is a connection between the hose 1 and an attached blank of a branch hose 7 produces. This branch hose 7 is also aufördeh at the edges 8. The flared edges 8 and 2 overlap and are at the same time through the funnel-shaped rubber loop 4 over the full overlap zone under gluing. The web beam 6 engages by means of a pin 9 in the crossbeam 3 to create a fixed position so that during vulcanization Displacements cannot occur due to a folded sleeve. This sleeve consists of an approximately funnel-shaped part 10. This part 10 engages around the hose I on both sides up to a zone 11. A Another shell part 12 engages around the front and back of the hose 1 in the lower area. The bowl 12 is connected to the funnel-shaped part 10 in the zone Π. They are by means of a clamping device held together so that vulcanization can take place with simultaneous shaping. Of the Crossbar 3 can be bent at an angle in the middle. Furthermore, the web beam 6 can also be attached at an oblique angle be. This enables T-shaped rubber hose branches in many designs.
