Description
Rauh- und Schneidvorrichtung für LuftschläucheRaising and cutting device for air hoses
Die Erfindung betrifft eine Rauh- und Schneidvorrichtung für iuftschläuche, insbesondere für Fahrradreifen, zum Einschneiden eines Ventilloches und Aufrauhen der Umgebungsfläche.The invention relates to a roughening and cutting device for air hoses, especially for bicycle tires, for cutting a valve hole and roughening the surrounding area.
Bei Fahrradschläuchen mit anvulkanisierten Gummifußventilen war es bisher üblich, Schlauch und Gummifuß des Ventils im noch unvulkanisierten Zustand zusammenzubringen und gemeinsam auszuvulkanisieren.It was the case with bicycle tubes with vulcanized rubber foot valves Previously common, the hose and rubber base of the valve were still unvulcanized bring together and vulcanize out together.
Bei einer Scblauchfertigung, bei der Schlauch endlos auf einem Extruder gespritzt und anschließend kontinuierlich, beispielsweise im Salzbar vulkanisiert wird, um anschließend auf Fertigmaßabschnitte zugeschnitten und konfektioniert zu werden,ergeben sich jedoch Schwierigkeiten um eine feste Verbindung zwischen dem Gummifußventil und dem bereits ausvulkanisierten Schlauch zu erreichen, da ein herkömmliches Aufkleben mit einer entsprechenden Gummi lösung nicht die erforderliche Dauerfestigkeit bringt.In the case of hose production, where the hose is endlessly on an extruder injected and then continuously vulcanized, for example in a salt bar is then cut to finished size sections and assembled are, however, difficulties arise in order to establish a permanent connection between the Rubber foot valve and the already vulcanized hose, as a conventional one Gluing with an appropriate rubber solution does not have the required fatigue strength brings.
Bei einem derartigen Herstellungsverfahren ist es daher erforderlich, an der Aufsatzstelle des Gummifußventi-ls ein entsprechendes Ventilloch in eine Wandung des Schlauches zu schneiden und die Umgebung dieses Ventilloches für das Anvulkanisieren des Gummifuflventils entsprechend aufzurauhen.In such a manufacturing process, it is therefore necessary at the attachment point of the rubber foot valve, insert a corresponding valve hole into a To cut the wall of the hose and the area around this valve hole for the Roughen the vulcanization of the rubber fill valve accordingly.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zu schaffen mit der es möglich ist, das Aufrauhen des Schlauches und das Einschneiden des Ventiles in ein und demselben Arbeitsgang durchzuführen.The invention is therefore based on the object of providing a device create with which it is possible to roughen the hose and cut it of the valve in one and the same work step.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß eine auf dem in einer Halterung liegenden flachen Schlauch absenkbare, kreisförmige Rauhscheibe vorgesehen ist, die in ihrem Zentrum einen nach unten herausragenden Schneidansatz mit einer Höhe entsprechend der Dicke der Schlauchwandung zum Einschneiden des Ventilloches trägt.To solve this problem, the invention provides that a Circular buffing disc that can be lowered onto the flat hose in a holder is provided, which has a downwardly protruding cutting attachment in its center with a height corresponding to the thickness of the hose wall for cutting the valve hole wearing.
Damit ist es auf einfache Weise möglich, an einer beliebigen Stelle des Schlauchumfangs ein Ventilloch nur einseitig in den Schlauch zu schneiden.This makes it possible in a simple way, at any point around the circumference of the hose to cut a valve hole in the hose only on one side.
Anhand einer schematischen Zeichnung sind Aufbau und Wirkungsweise eines Ausführungsbeispiels nach der Erfindung näher erläutert. Dabei zeigen: Fig. 1 eine schematische Seitenansicht einer Rauh-und Schneidvorrichtung für das Ventilloch, Fig. 2 einen Längsschnitt durch einen Schlauchabschnitt im Fertigzustand im Bereich des Ventilloches und Fig. 3 eine Aufsicht auf diesen Schlauchabschnitt mit der aufgerauhten Stelle und dem Ventilloch.A schematic drawing shows the structure and mode of operation an embodiment according to the invention explained in more detail. They show: Fig. 1 a schematic side view of a roughening and cutting device for the valve hole, 2 shows a longitudinal section through a tube section in the finished state in the area of the valve hole and FIG. 3 shows a plan view of this hose section with the roughened one Place and the valve hole.
Wie aus Fig. 1 zu ersehen ist, wird auf eine flache Halterung 1 mit zwei Anschlägen 2 und 3 an der hinteren Kante der Halterung 1 ein Schlauch 4 mit Schlauchoberseite 5 und Schlauchunterseite 6 im praktisch luft losen Zustand so aufgelegt, daß er bündig an die beiden Anschläge 2 und 3 anliegt. Die korrekte Lage des Schlauches wird dabei durch zwei Photozellen 7 und 8 überwacht.As can be seen from Fig. 1, is on a flat bracket 1 with two stops 2 and 3 on the rear Edge of bracket 1 Hose 4 with hose top 5 and hose bottom 6 in practically airless State placed in such a way that it is flush with the two stops 2 and 3. the The correct position of the hose is monitored by two photocells 7 and 8.
Oberhalb des so in Position gebrachten Schlauches 1 ist nunmehr eine ebene, kreisförmige Rauhscheibe 9 über einen Stempel 10 absenkbar gehalten, die die Schlauchoberseite 5 im Bereich des aufzubringenden Gummifußventils aufrauht. Gleichzeitig trägt diese Rauhscheibe 9 im Zentrum einen Schneidansatz 11, der maximal die Höhe entsprechend der Dicke der oberen Schlauchwandung 5 aufweist. Nach Absenken der Rauhscheibe 9 wird somit ein Ventilloch geschnitten und die Schlauchoberseite 2 entsprechend aufgerauht.Above the thus brought into position hose 1 is now a flat, circular roughing disc 9 held lowerable via a punch 10, the roughening the upper side of the hose 5 in the area of the rubber foot valve to be applied. At the same time, this rough wheel 9 has a cutting attachment 11 in the center, the maximum has the height corresponding to the thickness of the upper hose wall 5. After lowering the roughing disk 9 is thus cut a valve hole and the upper side of the tube 2 roughened accordingly.
Der fertiqe Schlauchabschnitt ist in den Fig. 2 und 3 gezeigt. Dabei erkennt man das in die Schlauchoberseite 5 eingeschnittene Ventilloch 12 sowie den kreisförmig aufgerauhten Bereich 13 in der Umgebung des Ventilloches 12,auf den anschließend das eigentliche Gummifußventil 14 mit seiner Unterseite 15 aufgesetzt und anvulkanisiert wird.The finished tube section is shown in FIGS. Included one recognizes the valve hole 12 cut into the tube top 5 as well as the circular roughened area 13 in the vicinity of the valve hole 12 on the then the actual rubber foot valve 14 is placed with its underside 15 and vulcanized.
Mit der beschriebenen Vorrichtung ist es also auf einfache Weise möglich, in einem einzigen Arbeitsgang bei aufeinanderliegendem Schlauch ein Ventilloch in nur eine Wandung des Schlauches einzuschneiden und gleichzeitig die Umgebung des Ventilloches aufzurauhen.With the device described, it is therefore possible in a simple manner a valve hole in a single operation with the hose lying on top of one another to cut only one wall of the hose and at the same time the area around the Roughen valve holes.
