Abstract

The method involves welding plastic parts with one another, and pressing regions of the plastic parts against each other after heating at welding temperature. The regions are provided with a profile (4), which increases a surface of the respective plastic parts. The profile is formed by ribs running parallel to each other, where a cross section of the profile is outwardly tapered and run outwardly. A connecting flange (1) of a plastic housing (2) is provided at a flange surface (3) with the profile, where the flange surface is provided for a welded joint with a corresponding counter flange.

Description

[0001] Die Erfindung betrifft ein Verfahren zum Heissgasschweissen von Kunststoffteilen, bei dem die miteinander zu verschweissenden Bereiche der Kunststoffteile nach Erhitzen auf Schweisstemperatur gegeneinandergepresst werden. The invention relates to a method for hot gas welding of plastic parts, in which the areas to be welded together of the plastic parts are pressed against each other after heating to welding temperature.

[0002] Der Erfindung liegt die Aufgabe zugrunde, ein insbesondere für die automatisierte Zusammenfügung und Verschweissung geeignetes Verfahren zu finden das mit geringerem Zeitaufwand und somit erhöhter Produktivität ausführbar ist. Die Lösung dieser Aufgabe erfolgt erfindungsgemäss aufgrund der kennzeichnenden Merkmale des Patentanspruchs. The invention has for its object to find a suitable in particular for the automated assembly and welding process that is executable with less time and thus increased productivity. The solution of this object is achieved according to the invention by the characterizing features of the claim.

[0003] Ein Ausführungsbeispiel für die Anwendung der Erfindung ist in der Zeichnung dargestellt. Diese zeigt in perspektivischer Darstellung einen Ausschnitt des Verbindungsflansches eines Kunststoffgehäuses. An embodiment of the application of the invention is shown in the drawing. This shows a perspective view of a section of the connecting flange of a plastic housing.

[0004] Wie die Zeichnung zeigt, ist der Flansch 1 eines Kunststoffgehäuses 2 an seiner für die Schweissverbindung mit einem entsprechend geformten Gegenflansch bestimmten Flanschfläche 3 mit einer Profilierung 4 versehen. Diese hat die Aufgabe die beim Heissgassverschweissen mit dem Gegenflansch bestimmte Oberfläche für die Wärmeübertragung wesentlich zu vergrössern, so dass in Kontakt mit dem von einem Heissgasschweissgerät zugeführten Heissgas in kürzerer Zeit eine für die Materialverschweissung ausreichende Menge an Wärmeenergie in das Kunststoffmaterial eingeleitet wird. Beim anschliessenden Zusammenpressen der Flanschfläche mit derjenigen des Gegenflansches wird die Profilierung der Flanschfläche flachgepresst, so dass die Verschweissung an einer sich dabei vergrössernden Fläche erfolgt. As the drawing shows, the flange 1 of a plastic housing 2 is provided at its particular for the welded connection with a correspondingly shaped counter flange flange 3 with a profiling 4. This has the task to significantly increase the surface area for the heat transfer when hot-gas welding with the mating flange so that a quantity of heat energy sufficient for material fusion is introduced into the plastic material in a shorter time in contact with the hot gas supplied by a hot-gas welding device. During the subsequent compression of the flange surface with that of the mating flange, the profiling of the flange surface is pressed flat, so that the welding takes place on an area which is thereby increasing.

[0005] Vorteilhaft besteht die Profilierung aus mehreren, parallel zueinander verlaufenden Rippen, deren Querschnitt nach aussen spitz ausläuft, so dass der äussere Bereich der Profilierung schneller erhitzt wird. Advantageously, the profiling of a plurality of mutually parallel ribs whose cross-section tapers to the outside, so that the outer region of the profiling is heated faster.

[0006] Der nichtdargestellte Gegenflansch kann gleichartig, andersartig oder überhaupt nicht profiliert sein, jedoch ist auch für dessen schnellere Erwärmung im Heissgasstrom eine Profilierung von Vorteil. The counter flange not shown may be similar, different or not profiled at all, but is also for its faster heating in the hot gas flow profiling advantageous.
