Abstract
Description
Die Erfindung bezieht sich auf eine Heftnadel für eine Verbindungsvorrichtung zum temporären Verbinden von wenigstens zwei vorzugsweise plattenartigen Teilen, insbesondere zum Verbinden von zwei zu verklebenden und/oder zu vernietenden Teilen gemäß dem Oberbegriff des Anspruchs 1. Das bevorzugte Einsatzgebiet der Erfindung ist die Luft- und Raumfahrttechnik.The invention relates to a stapling needle for a connecting device for temporarily connecting at least two preferably plate-like parts, in particular for connecting two parts to be bonded and / or riveted according to the preamble of
Eine bekannte Verbindungsvorrichtung des erfindungsgemäßen Prinzips ist in
Um die zumindest zwei plattenförmigen Teile miteinander zu verspannen, werden die Heftnadeln durch eine maßgenaue Öffnung geführt, dann gespreizt, so dass die hakenförmigen Enden den Rand der Öffnung übergreifen. Beim Verspannen der Heftnadeln presst die Verbindungsvorrichtung die zu verbindenden Teile zusammen. Wenn diese Teile, wie im Flugzeugbau üblich, miteinander verklebt werden, kann Klebstoff in die Öffnungen gelangen, der die Heftnadeln kontaminiert. Im schlimmsten Fall können die Heftnadeln derart verkleben, dass die Verbindungsvorrichtung nicht mehr gelöst werden kann, weil sich die Spreizung der Heftnadeln nicht mehr aufheben lässt.In order to clamp the at least two plate-shaped parts together, the stapling needles are guided through a dimensionally accurate opening, then spread, so that the hook-shaped ends overlap the edge of the opening. When tightening the stapling needles, the connecting device presses the parts to be joined together. If these parts are glued together, as is usual in the aircraft industry, glue can get into the openings, which contaminates the staple needles. In the worst case, the staple needles can stick so that the connection device can not be solved because the spread of stapling needles can not be canceled.
Der Erfindung liegt das Problem zugrunde, eine Heftnadel zur Verfügung zu stellen, welche die negativen Auswirkungen von Klebstoff-Kontaminationen deutlich reduziert.The invention is based on the problem of providing a stitching needle which significantly reduces the negative effects of adhesive contamination.
Die Problematik wird erfindungsgemäß gelöst durch eine Heftnadel gemäß den kennzeichnenden Merkmalen des Anspruchs 1. Demnach weist zumindest ein Teilbereich der äußeren Kontur der Heftnadel Mittel auf, die einem Verkleben der paarweise angeordneten Heftnadeln entgegenwirken.The problem is solved according to the invention by a stitching needle according to the characterizing features of
Gemäß einer Vorzugsvariante der Erfindung werden die Mittel zum Schutz vor Verklebung durch eine Umhüllung des Grundkörpers der Heftnadel gebildet. Idealerweise wird die Umhüllung durch Umspritzen mit einem entsprechend geeigneten Kunststoff erzeugt, wobei die Umhüllung sehr dünn ausgeführt sein kann.According to a preferred variant of the invention, the means for protection against adhesion by an envelope of the main body of the stitching needle are formed. Ideally, the casing is produced by molding with a suitably suitable plastic, wherein the casing can be made very thin.
Sofern die Heftnadel selbst aus Kunststoff, insbesondere einem faserverstärkten Kunststoff gefertigt ist, sollte die Kunststoffmatrix die gewünschten Eigenschaften aufweisen, das heißt dass der Kunststoff keine oder keine gute Verbindung mit dem Klebstoff eingeht. Allerdings ist es auch möglich, eine Oberflächenbehandlung des Grundkörpers der Kunststoff-Heftnadel vorzusehen, die geeignet ist, einer Verbindung mit den zu erwartenden Kontaminations-Materialien (insb. Klebstoffen) entgegenzuwirken. Zu diesem Zweck können chemischer Mittel, z. B. mittels CVD (Chemical Vapor Deposition) oder physikalischer Mittel, z. B. mittels ionisierender Strahlung, zur Anwendung kommen.If the stitching needle itself is made of plastic, in particular a fiber-reinforced plastic, the plastic matrix should have the desired properties, that is to say that the plastic makes no or no good connection with the adhesive. However, it is also possible to provide a surface treatment of the base body of the plastic stitching needle, which is suitable for counteracting a connection with the expected contamination materials (in particular adhesives). For this purpose, chemical agents, for. B. by CVD (Chemical Vapor Deposition) or physical means, for. B. by ionizing radiation, are used.
Grundsätzlich können aber auch mechanischer Mittel vorgesehen werden, die geeignet sind, negative Auswirkungen der Kontamination mit Klebstoff zu vermeiden oder zu reduzieren. Beispielsweise können seitlich an den Heftnadeln angeformte Schutzlippen die Gefahr reduzieren, dass in Bereich der einander zugewandten inneren Flächen der Heftnadeln Klebstoff eindringt. Aber auch ein elastischer Schutzschlauch, der über die Heftnadeln gezogen und bei Bedarf entfernt wird, kann die gewünschte Wirkung entfalten.In principle, however, it is also possible to provide mechanical means which are suitable for avoiding or reducing negative effects of contamination with adhesive. For example, protective lips integrally formed laterally on the stapling needles reduce the risk of adhesive penetrating in the area of the inner surfaces of the stapling needles facing each other. But even an elastic protective tube, which is pulled over the stapling needles and removed if necessary, can develop the desired effect.
Nachfolgend wird die erfindungsgemäße Heftnadel anhand von Ausführungsbeispielen und den dargestellten Figuren näher erläutert. Um eine umfangreiche und ausführliche Erklärung des Aufbaus und der Wirkungsweise der zugehörigen anderen mechanischen Teile der Verbindungsvorrichtung zu vermeiden, werden ausdrücklich die Offenbarungen der deutschen Gebrauchsmusteranmeldung
