Stand der TechnikState of the art
Die Erfindung betrifft ein Trägerteil mit einer Nut zur Aufnahme eines Kunststoffbauteils, wobei das Kunststoffbauteil einen metallischen Überzug aufweist.The invention relates to a carrier part with a groove for receiving a plastic component, wherein the plastic component has a metallic coating.
Ein solcher Aufbau dient beispielsweise dazu, Schriftzüge, Typenbezeichnungen oder Symbole an einem Trägerteil zu befestigen. Üblicherweise wird das Kunststoffbauteil geklebt oder es weist stiftförmige Ansätze auf, die durch Öffnungen des Trägerteils gesteckt und anschließend unter Einwirkung von Wärme plastisch verformt werden.Such a structure is used, for example, to attach lettering, type designations or symbols to a carrier part. The plastic component is usually glued or it has pin-shaped attachments that are inserted through openings in the carrier part and then plastically deformed under the influence of heat.
Bei dem Verkleben der beiden Teile miteinander besteht die Gefahr, dass bei hoher mechanischer oder thermischer Beanspruchung die Verbindung reißt. Außerdem erfordert das Verkleben durch die Verwendung eines Zusatzwerkstoffes höhere Herstellkosten. Bei einem Verbinden über thermisch verformbare Stifte läßt sich keine zuverlässige Abdichtung zwischen Kunststoffbauteil und Trägerteil erzielen.When gluing the two parts together, there is a risk that the connection will tear if subjected to high mechanical or thermal stress. In addition, gluing requires higher manufacturing costs due to the use of additional material. When connecting using thermally deformable pins, a reliable seal cannot be achieved between the plastic component and the carrier part.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Trägerteil zu schaffen, welches sowohl hohen mechanischen als auch hohen thermischen Belastungen standhält und eine zuverlässige Abdichtung zwischen Kunststoffbauteil und Trägerteil bewirkt.The invention is therefore based on the object of creating a carrier part which can withstand both high mechanical and high thermal loads and which ensures a reliable seal between the plastic component and the carrier part.
Diese Aufgabe wird ausgehend von dem Oberbegriff des unabhängigen Anspruchs 1 dadurch gelöst, dass hier das Trägerteil 10 im Bereich der Aufnahme für das Kunststoffbauteil 11 eine Nut aufweist und das Kunststoffbauteil 11 mit einer Verbindungsstelle versehen ist und die Verbindung mittels erwärmen des Kunststoffbauteils und des Trägerteils im Bereich der Verbindungsstelle erfolgt und wobei das Kunststoffbauteil im Bereich der Verbindungsstelle eine metallfreie Zone aufweist.This object is achieved on the basis of the preamble of independent claim 1 in that the carrier part 10 has a groove in the region of the receptacle for the plastic component 11 and the plastic component 11 is provided with a connection point and the connection is made by heating the plastic component and the carrier part in the region of the connection point and wherein the plastic component has a metal-free zone in the region of the connection point.
Der wesentliche Vorteil der Erfindung liegt darin, dass über die metallfreie Zone des Kunststoffbauteils eine, -sofern das Trägerteil kein thermoplastischer Kunststoff ist-, formschlüssige Verbindung erfolgen kann. Sofern das Trägerteil ebenfalls aus Kunststoff besteht, erfolgt durch das Erwärmen des Kunststoffbauteils eine Schmelzverbindung der beiden Teile miteinander.The main advantage of the invention is that a positive connection can be made via the metal-free zone of the plastic component - provided the carrier part is not made of thermoplastic. If the carrier part is also made of plastic, the two parts are fused together by heating the plastic component.
• ··
In einer vorteilhaften Ausgestaltung der Erfindung besteht sowohl das Trägerteil als auch das Kunststoffbauteil aus einem Thermoplast. Dieser Werkstoff eignet sich hervorragend zum thermischen Verbinden.In an advantageous embodiment of the invention, both the carrier part and the plastic component are made of a thermoplastic. This material is ideally suited for thermal bonding.
Die Verbindung erfolgt gemäß einer weiteren Ausgestaltung der Erfindung mittels Ultraschall oder Reibschweißen. Selbstverständlich sind auch andere Schweißverfahren denkbar, wie beispielsweise das Verschweißen über Induktionswärme oder das Heizelementschweißen. Durch entsprechende Ausgestaltung der metallfreien Zone des Kunststoffbauteils ist eine druckfeste Abdichtung zwischen Trägerteil und Kunststoffbauteil möglich.According to a further embodiment of the invention, the connection is made by means of ultrasound or friction welding. Of course, other welding methods are also conceivable, such as welding using induction heat or heating element welding. By appropriately designing the metal-free zone of the plastic component, a pressure-tight seal between the carrier part and the plastic component is possible.
In einer weiteren vorteilhaften Ausgestaltung weist das Trägerteil einen Schweißring oder Schweißrand auf. Dieser Schweißrand kontaktiert mit seiner Spitze die metallfreie Zone des Kunststoffbauteils und sorgt beim Verschweißen der beiden Teile für die erforderliche Abdichtung.In a further advantageous embodiment, the carrier part has a welding ring or welding edge. The tip of this welding edge contacts the metal-free zone of the plastic component and ensures the necessary sealing when the two parts are welded together.
Beim Montieren der beiden Teile erleichtert in einer Weiterbildung der Erfindung ein Zentrierrand die Zusammenfügung der beiden Teile.When assembling the two parts, in a further development of the invention, a centering edge facilitates the joining of the two parts.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer
aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die
einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von
Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten
verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen
können, für die hier Schutz beansprucht wird.These and other features of preferred developments of the invention go beyond
from the claims and from the description and the drawings, whereby the
individual features either individually or in groups in the form of
Subcombinations in the embodiment of the invention and in other fields
be implemented and represent advantageous and protectable designs
for which protection is claimed here.

Das Trägerteil 10 gemäß Figur 1 ist beispielsweise eine Abdeckhaube oder ein Frontbauteil, an dem ein Emblem angebracht werden soll.The carrier part 10 according to Figure 1 is, for example, a cover or a front component to which an emblem is to be attached.
Im vorliegenden Fall handelt es sich um die Abdeckhaube eines Luftfilters für die Ansaugluft einer Brennkraftmaschine. Auf dieser Abdeckhaube ist das Emblem des Fahrzeugherstellers oder des Ansaugsystemherstellers anzubringen. Dieses Emblem ist ein Kunststoffbauteil 11, welches mit dem Trägerteil 10 abdichtend und zuverlässig verbunden werden muß. Das Kunststoffbauteil 11 ist mit einem metallischen Überzug, insbesondere einem Überzug aus Chrom versehen. Das Trägerteil 10 weist im Bereich der Aufnahme für das Kunststoffbauteil 11 eine Nut 12 auf. Das Kunststoffbauteil 11 ist mit einem Ringwulst 13 zum Einfügen in die Nut ausgestattet. Die zu der Nut 12 hinweisende Fläche 14 des Ringwulstes 13 wurde vor dem Aufbringen des metallischen Überzugs mit einem Lack versehen, welcher das Auftragen von Metall unterbindet. Das Trägerteil 10 kann über die Befestigungsstrukturen 15, 16 mit einem hier nicht dargestellten Grundkörper oder Gehäuse verbunden werden.In the present case, it is the cover of an air filter for the intake air of an internal combustion engine. The emblem of the vehicle manufacturer or the intake system manufacturer is to be attached to this cover. This emblem is a plastic component 11 which must be connected to the carrier part 10 in a sealing and reliable manner. The plastic component 11 is provided with a metallic coating, in particular a chrome coating. The carrier part 10 has a groove 12 in the area where the plastic component 11 is received. The plastic component 11 is equipped with an annular bead 13 for insertion into the groove. The surface 14 of the annular bead 13 facing the groove 12 was coated with a lacquer before the metallic coating was applied, which prevents the application of metal. The carrier part 10 can be connected to a base body or housing (not shown here) via the fastening structures 15, 16.

Das Trägerteil 10 weist in der Nut 12 einen Schweißring 17 auf. Dieser Schweißring ist dreieckförmig ausgestaltet und ermöglicht eine zuverlässige Verbindung des Kunststoffbauteils 11 an dem Trägerteil 10 mittels Reibschweißen. Zum Verschweißen wird das Trägerteil 10 auf einen Amboß 18 aufgelegt. Das Kunststoffbauteil 11 wird mit einem Schweißstempel 19 unter Einwirkung von Vibration auf das Trägerteil 10 zubewegt und mit diesem im Bereich des Schweißrings 17 verschweißt. Durch die ringförmige Ausgestaltung des Schweißrings 17 erfolgt eine zuverlässige Abdichtung der Öffnung des Trägerteils 10. Zwischen den beiden Teilen kann noch eine toleranzausgleichende Zwischenlage 20 eingelegt werden.The carrier part 10 has a welding ring 17 in the groove 12. This welding ring is triangular in shape and enables a reliable connection of the plastic component 11 to the carrier part 10 by means of friction welding. For welding, the carrier part 10 is placed on an anvil 18. The plastic component 11 is moved towards the carrier part 10 with a welding stamp 19 under the influence of vibration and is welded to it in the area of the welding ring 17. The ring-shaped design of the welding ring 17 ensures a reliable seal of the opening of the carrier part 10. A tolerance-compensating intermediate layer 20 can also be inserted between the two parts.
