Abstract

T-shaped rubber pipe branch with fabric reinforcement layers is made by (a) forming an opening in the wall of a vulcanisable pipe section, (b) flanging the edges of the opening in an outwards direction, (c) cementing a funnel-shaped vulcanised rubber piece under the flanged edge of the opening, (d) outwardly flanging the edges of the vulcanisable rubber pipe branch before it is inserted in the opening, and (e) forming the overlapping edges of the wall opening and the pipe branch with simultaneous vulcanisation of these parts. Rapid, easily controlled method. Does not break the rubber reinforcement layers. Strong bond between the pipe section and the branch section.

Description

Zur Durchführung des erfindungsgemäßen Verfahrens dient eine Vorrichtung mit einer einen T-förmigen 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 ist. Die Vorrichtung zeichnet sich erfindungsgemäß dadurch aus, daß die Teilung zwischen dem Querbalken und dem Stegbalken des Dornes in der Überlappungszone des Randes der Wandöffnung des Schlauches und des Randes des Abzweigschlauches liegt. A device is used to carry out the method according to the invention with a T-shaped Having a mold cavity in an axial plane of the hose divided into two shell parts and a mandrel with an im essential cylindrical crossbeam to which a web beam can be attached. the Device is characterized according to the invention in that the division between the cross bar and the web bar of the mandrel in the overlap zone of the edge the wall opening of the hose and the edge of the branch hose.

Vorteilhafterweise ist der Stegbalken mit einem Zapfen in eine Aussparung des Querbalkens einsetzbar. The web beam is advantageously in a recess with a pin of the crossbar can be used.

Die Erfindung wird in Verbindung mit einer Abbildung beschrieben. Diese zeigt einen Querschnitt durch die T-förmige Zone der Gummischlauchverzweigung, durch den 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, by the mandrel located in it and by the encompassing 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 aufgebördelt. Der Schlauch 1 sitzt dabei auf einem Querbalken 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 Gum- mischlauchstück 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 aufgebördelt. According to the picture, one is reinforced with a fabric reinforcement insert Provided the blank of a hose 1 with an approximately round opening. The edges 2 of these openings are flared to the outside. The hose 1 sits on it a crossbar 3 of a mandrel. Between the crossbar 3 and the hose 1, a funnel-shaped piece of rubber hose 4 is inserted, which has the division 5 with overlaps a web beam 6 of the mandrel to some extent. This rubber mixed hose piece 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 flared at the edges 8.

Die aufgebördelten Ränder 8 und 2 überlappen sich und sind gleichzeitig durch das trichterförmige Gummischlauchstück 4 über die volle Überlappungszone unter Verklebung unterlegt. 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 1 auf beiden Seiten bis in eine Zone 11. Ein weiteres Schalenteil 12 umgreift die Vorder- und Rückseite des Schlauches 1 im unteren Bereich. Das Schalenteil 12 ist in der Zone 11 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.The flared edges 8 and 2 overlap and are at the same time through the funnel-shaped piece of rubber hose 4 over the full overlap zone Bonding underlaid. The web beam 6 engages in the transverse beam by means of a pin 9 3 a to create a fixed position so that displacements during vulcanization cannot enter through a folded sleeve. This sleeve consists of one approximately funnel-shaped part 10. This part 10 engages around the tube 1 on both sides Pages up to a zone 11. Another shell part 12 engages around the front and Back of hose 1 in the lower area. The shell part 12 is in the zone 11 connected to the funnel-shaped part 10. They are by means of a clamping device held together so that vulcanization takes place with simultaneous shaping can. The crossbar 3 can be bent at an angle in the middle.

Ferner kann auch der Stegbalken 6 schiefwinklig angesetzt sein. Dadurch sind T-förmige Gummischlauchverzweigungen in vielen Gestaltungen möglich.Furthermore, the web beam 6 can also be attached at an oblique angle. Through this T-shaped rubber hose branches are possible in many designs.

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer T-förmigen Gummischlauchverzweigung mit Gewebeverstärkungseinlagen gemäß dem Gattungsbegriff des vorstehenden Patentanspruchs 1. The invention relates to a method for producing a T-shaped rubber hose branching with fabric reinforcement inserts according to the 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 automotive engineering, branches of hoses are required for various purposes. To this To meet demand, the hoses were previously made using T-shaped metal pipe parts tied together. The connection between these and the hose requires a precise one inner width of the hose and fastening by means of hose clamps. Such Hose clamps are particularly useful where there are constant vibrations and Temperature fluctuations occur, proven to be insufficiently safe. Lack useful T-shaped rubber hose branches had this disadvantage up to now, however be accepted. Es ist ein Verfahren zum Herstellen einer T-förmigen 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 Abzweigschlauches durch Vulkanisation miteinander verbunden werden. It is a method of making a T-shaped rubber hose branch known with fabric reinforcement inserts, in which one in the wall of a hose Wall opening formed, the edge of which is machined, additional material on the edge of the Wall opening attached and a branch hose is inserted into the wall opening and the edges of the wall opening and the branch hose together by vulcanization get connected. Bei diesem Verfahren werden die Verbindungsflächen der beiden Schlauchteile mit einer Ansenkung versehen und es wird eine Kautschukhaftmischung zwi schen 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. In this process, the connecting surfaces of the two hose parts provided with a countersink and there is an adhesive rubber mixture between these rule Joint surfaces brought and vulcanized. Depending on the rubber compound structure of the Hoses can vulcanize in an adhesive mixture between the finished vulcanized Hose parts can be associated with various difficulties. Especially with Such a connection is difficult to achieve with thin-walled hoses Create detention security. Complete coverage of the hose connection points exiting fabric reinforcement inserts also requires a constant and careful monitored manufacturing process. Nachteilig ist ferner, daß gerade in der Verbindungsschicht die Gewebeverstärkungseinlage unterbrochen ist.A further disadvantage is that the fabric reinforcement insert is precisely in the connecting layer is interrupted. Aufgabe der Erfindung ist es, ein Verfahren zum Herstellen einer T-förmigen Gummischlauchverzweigung, wie sie eingangs umrissen worden ist, zu schaffen, bei dem unter Vermeidung der obengenannten Nachteile in der Verbindungsstelle der Schlauchteile eine hohe Festigkeit erhalten wird, ohne daß die Herstellung eine über das übliche hinausgehende Sorgfalt 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. The object of the invention is to provide a method for producing a To create a T-shaped rubber hose branch, as outlined at the beginning, in the avoidance of the above-mentioned disadvantages in the junction of the Hose parts high strength is obtained without the production of a Requires more than usual care. This task is performed according to the Invention can be achieved in that the formation of the wall opening in a still vulcanizable Blank of a hose is made, the edge of the wall opening after machining beaded on the outside, a funnel-shaped vulcanized one to attach the additional material A piece of rubber hose is glued under the beaded edge of the wall opening and the edge of the branch hose, which can also still be vulcanized, before it is inserted is also crimped to the outside in the wall opening and the connection of the overlapped edges of the wall opening and the branch hose at the same time 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 manner Wise and does not require any care that goes beyond the usual operational care Execution. The workflow is hardly prone to failure. The funnel-shaped piece of rubber hose and the flanged edges of the hose parts pushed one on top of the other can be securely associate. 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, is the compressive strength in the T-area is particularly high. If used excessively, it bursts the rubber hose branching only outside this area. The funnel-shaped The rubber hose section is matched to the rubber compound of the hose blank parts. If this is based on polychlorobutadiene, then the funnel-shaped piece of rubber hose is constructed in the same way. Since before vulcanization when placing the funnel-shaped If the rubber hose piece is glued, this is also the case with the mix build-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 fibers such as rayon can be used.
