Description

Verfahren zum Verschweißen von ineinandergreifenden Formteilen aus thermoplastischem Kunststoff Es ist bekannt, zum Verschweißen von ineinandergreifenden Formteilen aus thermoplastischem Kunststoff, insbesondere von Rohren und Rohranschlußteilen, eine metallische Einlage zwischen die Schweißflächen zu bringen und diese Einlage elektroinduktiv zu erwärmen. Als metallische Einlage hat man z. B. einen Blechring verwendet. Es ist auch bekannt, zwischen die ebenen Schweißflächen von durch elektroinduktive Erhitzung zu verbindenden Werkstücken aus thermoplastischen Kunststoffen Metallpulver zu verwenden, jedoch handelt es sich hierbei nicht um das Verschweißen ineinandergreifender Formteile wie Rohre und Rohranschlußteile. Process for welding interlocking molded parts thermoplastic plastic It is known for welding interlocking Molded parts made of thermoplastic material, in particular of pipes and pipe connection parts, to bring a metallic insert between the welding surfaces and this insert to be heated electroinductively. As a metallic insert you have z. B. a sheet metal ring used. It is also known between the flat welding surfaces by electro-inductive Heating to be joined workpieces made of thermoplastics metal powder to use, but this is not the welding of interlocking Molded parts such as pipes and pipe connection parts.

Erfindungsgemäß wird für das Verschweißen ineinandergreifender Formteile aus thermoplastischen Kunststoffen bei der an sich bekannten Verwendung einer metallischen Einlage aus Metallpulver dieses mit einem Kunststoff zu einer Folie verknetet. Hierbei können die Metallpulverteilchen in ihrer Form, Größe und Menge zu der für die Verknetung verwendeten Kunststoffmenge so abgestimmt werden, daß eine gleichmäßige Verteilung der Schmelzwärme im Kunststoff erzielt wird. According to the invention for the welding of interlocking molded parts made of thermoplastics with the known use of a metallic Insert made of metal powder kneaded with a plastic to form a film. Here The shape, size and quantity of the metal powder particles can match those for kneading The amount of plastic used should be matched so that it is evenly distributed the heat of fusion in the plastic is achieved.

Mit Hilfe einer derartigen Folie, die sich bequem verformen und wickeln läßt, kann der Toleranzspalt zwischen den Werkstücken ohne Schwierigkeit ausgefüllt werden. With the help of such a film that can easily deform and wrap leaves, the tolerance gap between the workpieces can be filled without difficulty will.

Eine zweckmäßige Ausführungsmöglichkeit des Verfahrens nach der Erfindung besteht darin, daß mit mindestens einem der zu verschweißenden Formteile eine das Metallpulver enthaltende Kunststoff-Folie im Zuge der Herstellung des Formteiles vereinigt wird. An expedient embodiment of the method according to the invention is that with at least one of the molded parts to be welded a Plastic film containing metal powder in the course of the production of the molded part is united.

In einer weiteren Ausführung des Verfahrens gemäß der Erfindung werden die zu verschweißenden Formteile mit einer oder mehreren das Metallpulver enthaltenden Kunststoff-Folien an den Schweißflächen, zweckmäßig durch thermische Formgebung, mit Gewinde versehen und zum Verschweißen ineinandergeschraubt. In a further embodiment of the method according to the invention the molded parts to be welded with one or more containing the metal powder Plastic foils on the welding surfaces, expediently through thermal shaping, provided with thread and screwed into each other for welding.

Ausführungsbeispiele von nach dem Verfahren gemäß der Erfindung hergestellten Rohrschweißverbindungen für Kunststoffrohre sind in den Abb. 1, 2 und 3 der Zeichnung im Längsschnitt dargestellt. Embodiments of manufactured by the method according to the invention Welded pipe connections for plastic pipes are shown in Figs. 1, 2 and 3 of the drawing shown in longitudinal section.

Bei allen drei Ausführungsbeispielen dient als Verbinder für die gleichachsigen Rohre a und b eine die Rohrenden aufnehmende Muffe c mit einem ringförmigen Innenvorsprung cl, der einen Anschlag für die Rohrenden bildet. In all three embodiments serves as a connector for the coaxial pipes a and b a sleeve c receiving the pipe ends with an annular Inner projection cl, which forms a stop for the pipe ends.

Bei dem Beispiel nach Abb. 1 sind die mit Spiel ineinandergreifenden Flächen der Rohrenden einerseits und der Muffe andererseits zylindrisch bzw. hohlzylindrisch. Der Ringspalt zwischen den zu verschweißenden Flächen wird durch eine Kunststoff-Folie ä, welche Metallpulver enthält, ausgefüllt. Das Metallpulver wird auf elektroinduktivem Wege erwärmt, wodurch die ineinandergreifenden Flächen der Werkstücke auf Schweißhitze gebracht werden. In the example of Fig. 1, the interlocking with play Surfaces of the pipe ends on the one hand and the sleeve on the other hand cylindrical or hollow-cylindrical. The annular gap between the surfaces to be welded is made up of a plastic film ä, which contains metal powder, filled out. The metal powder is electro-inductive Paths heated, whereby the interlocking surfaces of the workpieces on welding heat to be brought.

Rei dem Beispiel nach Abb. 2 sind die zu verschweißenden Flächen der Rohrenden a, b und der Muffe c mit zweckmäßig durch thermische Formgeb-1ng erzeugten Gewinden versehen. Die Rohrenden und die Muffe werden mit der das Metallpulver enthaltenden Kunststoff-Folie d ineinandergeschraubt, wonach das Metallpulver auf elektroinduktivem Wege zum Verschweißen der Gewindeflächen erwärmt wird. In the example according to Fig. 2, the surfaces to be welded are the pipe ends a, b and the sleeve c with expediently produced by thermal shaping Provide threads. The pipe ends and the socket are connected to the one containing the metal powder Plastic film d screwed into each other, after which the metal powder on electroinductive Ways to weld the threaded surfaces is heated.

Bei dem Beispiel nach Abb. 3 sind die ineinandergreifenden Flächen der Rohrenden a und b und der Muffe c mit Kunststoff-Folien e und f belegt, in welche das Metallpulver eingeknetet ist. Diese Kunststoff-Folien können mit den Rohrenden und mit der Muffe fest vereinigt sein. Durch Erwärmen des Metallpulvers auf elektroinduktivem Wege werden die Kunststoff-Folien und die benachbarten Flächen der Rohrenden und der Muffe aufgeschmolzen, wodurch die Verschweißung herbeigeführt wird. Selbstverständlich können auch diese mit den Formteilen vereinigten, das Metallpulver enthaltenden Kunststoff-Folien mit eingepreßtem Gewinde versehen sein. In the example of Fig. 3, the interlocking surfaces are the pipe ends a and b and the sleeve c covered with plastic foils e and f, in which the metal powder is kneaded. These plastic foils can be used with the pipe ends and be firmly united with the socket. By heating the metal powder on electro-inductive Paths are the plastic sheeting and the adjacent surfaces of the pipe ends and the sleeve is melted, which brings about the weld. Of course these can also be combined with the molded parts and containing the metal powder Plastic foils can be provided with a pressed-in thread.
