Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Verbindung zwischen einem glanzeloxierten Aluminium-Formteil, insbesondere einer Aluminium-Profilschiene und einem aus Kunststoff bestehenden Teil, insbesondere einer die Aluminium-Profilschiene gegen Stöße schützenden Leiste.The invention relates to a method for producing a connection between a shiny anodized Aluminum molded part, in particular an aluminum profile rail and one made of plastic Part, in particular a strip protecting the aluminum profile rail against impacts.

Der Verwendung von eloxierten Aluminium-Profilschienen als mit einem sogenannten Stoßkeder versehene Schutz- und Zierleisten von Kraftwagen steht entgegen, daß die für eine dauerhafte Verbindung des Stoßkeders mit der Aluminiumschiene erforderliche, verhältnismäßig hohe Temperatur und die dadurch hervorgerufene Ausdehnung der Aluminiumschiene die beim Eloxierverfahren gebildete zusammenhängende Oxydschicht zerstört bzw. zu Rißbildung in der Oberfläche dieser Schicht führtThe use of anodized aluminum profile rails as provided with a so-called bumper piping Protective and decorative strips of motor vehicles is contrary to the fact that the permanent connection of the Bumper trim with the aluminum rail required, relatively high temperature and the resulting caused expansion of the aluminum rail the coherent one formed during the anodizing process Oxide layer destroys or leads to the formation of cracks in the surface of this layer

Um diesen Nachteil zu vermeiden, wird gemäß der Erfindung vorgeschlagen, durch Beheizung des Aluminiumteils, nachdem dieser in bekannter Weise nach Aufbringen eines Klebstoffs mindestens auf eine der beiden miteinander zu verbindenden Flächen mit de;n Kunststoffteil verbunden wurde, den Klebstoff zu aktivieren und nach dessen Erhärten die freie Aluminiumfläche zu eloxieren.In order to avoid this disadvantage, it is proposed according to the invention, by heating the aluminum part, after this in a known manner after applying an adhesive to at least one of the the two surfaces to be connected with the plastic part was connected to the adhesive activate and anodize the free aluminum surface after it has hardened.

Vorteilhafterweise wird nach der Aktivierung des Klebstoffs der Aluminiumteil einer Zwangskühlung unterworfen, um dadurch die beiden miteinander verbundenen Teile in ihrer gegenseitigen Lage zu fixieren,Advantageously, after the adhesive has been activated, the aluminum part undergoes forced cooling subjected to thereby the two interconnected parts in their mutual position fix,

Die Klebeverbindung kann dadurch noch verbessert werden, daß die vom Klebstoff beaufschlagte Fläche des Aluminiumteils vorher aufgerauht wird.The adhesive bond can be further improved in that the area of the adhesive acted upon by the adhesive Aluminum part is roughened beforehand.

Die Aufheizung des Aluminiumteils kann mittels Stromdurchgang, mittels induktiver Wärmeerzeugung oder auch mittels Strahlungswärme erfolgen.The aluminum part can be heated by means of the passage of current, by means of inductive heat generation or by means of radiant heat.

Als Klebstoffe werden vorteilhafterweise solche verwendet, deren Aktivierung bei einer Temperatur über 1000C erfolgt.Such as adhesives are advantageously used, which are activated at a temperature above 100 0 C.
