Description

Es ist bekannt, daß man Bauteile aus thermoplastischen Kunststoffen durch Verschweißen miteinander verbinden kann. Bisher hat man die zur Durchführung des Schweißverfahrens erforderliche Erwäemung der Schweißnaht durch einen Heißluftstrom vorgenommen. Ein derartiges Schweißverfahren ist jedoch in mehrfacher Hinsicht nachteilig, insbesondere erfordert es eine große Geschicklichkeit, um einwandfreie Schweißnähte, die den mechanischen und elektrischen Beanspruchungen gewachsen sind, zu erzielen. Es ist besonders schwierig, mit dem Heißluftstrom Schweißkranten und Schweißdraht gleichzeitig auf die richtige Schweißtemperatur zu bringen. Bei Überhitzung tritt aber eine Verkokung ein, und der Werkstoff wird umbeauchbar. ein weiterer Nachteil ergibt sich dadurch, daß bleim Schweißen von durch Pressung geformten Kunststoffteilen eine Rückbildung der gepreßten Form infolge der Erwärmung der Bauteile durch den Heißluftstrom auftritt. It is known that components made of thermoplastics can be used can connect to each other by welding. So far you have to do it The welding seam required for the welding process by means of a stream of hot air performed. However, such a welding process is disadvantageous in several respects, in particular, it requires a great deal of skill to create perfect weld seams, that can cope with the mechanical and electrical stresses. It is particularly difficult to weld edges and wire with the hot air stream at the same time to bring it to the correct welding temperature. If overheated occurs but coking occurs, and the material can be converted into a convertible material. another disadvantage arises from the fact that lead welding of plastic parts formed by compression a regression of the pressed shape as a result of the heating of the components by the Hot air flow occurs.

Der Erfindung liegt der Gedanke zugrunde, zum Schweißen thermoplastischer Kunststoffe nicht Heißluft, sondern erhitzte, feste Körper nach Art von Lötkolben anzuwenden. Erfindungsgemäß ist daher für das Schweißen thermoplastischer Kunststoffe ein schneidenförmiger Schweißkolben mit einer führung und federbelasteten Vorschubrolle für den zur Herstellung der Schweißnaht dienenden Kunststoffdraht vorgesehen. Hiermit läßt sich die Erwärmung der Schweßnaht besser beherrschen und insbesondere auch eine unerwünschte Erwärmung der in der Nähe der Schweißnaht liegenden Teile der Kunststoffkörper vermeiden. Das Schweißen mit einem Schweißkolben ist ferner wesentlich einfacher zu handhaben und ergibt infolgedessen nicht so leicht wie das Heißluftschweißverfahren Fehlstellen in der Schweiß naht. The invention is based on the idea of thermoplastic welding Plastics are not hot air, but heated, solid bodies in the manner of soldering irons apply. According to the invention is therefore for welding thermoplastics a cutting-edge welding piston with a guide and spring-loaded feed roller intended for the plastic wire used to produce the weld seam. Herewith the heating of the weld seam can be better controlled and in particular also unwanted heating of the parts of the near the weld seam Avoid plastic bodies. Welding with a welding iron is also essential easier to handle and consequently not as easy to produce as the hot air welding process Defects in the sweat seam.

In der Abbildung ist die Erfindung an einem ausführungsbeispiel veranschaulicht. In the figure, the invention is illustrated using an exemplary embodiment.

Die beiden miteinander zu verschweißenden Kunststoffteile a und b werden an ihrer Naht stumpf gegeinandergestoßen und sodann durch Hinwegführen eines schneidenförmigen Schweißkolbens c unter gleichzeitiger Zuführung von schweißfähigem Kunststoff in Form eines Schweiß drahtes d miteinander verschweißt. The two plastic parts a and b to be welded together are butted against each other at their seam and then by leading one away cutting-edge welding piston c with simultaneous supply of weldable Plastic in the form of a welding wire d welded together.

Der Schweißkolben ist schneidenförmig zugespitzt, so daß die Erwärmung auf die Schweißnaht selbst beschränkt bleibt. Außerdem fällt die Ausschrängung der Schweißnähte fort, weil die keilförmige Schweißspitze diesen Arbeitsgang selbst übernimmt. Infolgendessen ist es möglich, auch gepreßte, z. B. kappenförmige Kunststoffkörper miteinander zu verschweißen, ohne durch Erwärmung größerer Teile des Kunststoffkörpers eine Zurückbildung der gepreßten Form befüßrchten zu müssen. The welding iron is pointed, so that the heating remains limited to the weld itself. In addition, the Welds continue because the wedge-shaped welding tip does this work itself takes over. In the following it is possible also pressed, z. B. cap-shaped plastic body to be welded together without heating larger parts of the plastic body having to fear a regression of the pressed shape.

Da der Kunststoff beim Schweißen nicht in den flüssigen, sondern lediglich in den plastisch verformbaren Zustand übergeführt wird, ist es erforderlich, den Schweißstand mit einem gewissen Druck in die Schweißnaht einzubringen. Um dies zu erleichtern, ist der Schweißkolben mit einer Führung f für den Schweißdraht versehen. Ferner wird der Schweißdraht durch eine gefederte Rolle g automatisch zugeführt. Die freibleibende Hand kann dann zum Führen und Halten des Werkstückes benutzt werden. Because the plastic is not in the liquid, but rather is only converted into the plastically deformable state, it is necessary to to bring the welding stand into the weld seam with a certain pressure. To this To make it easier, the welding iron is provided with a guide f for the welding wire. Furthermore, the welding wire is automatically fed by a spring-loaded roller g. The remaining hand can then be used to guide and hold the workpiece.

Die Erfindung ist nicht auf das dargestellte Beispiel beschränkt, vielmehr sind noch mancherlei Abänderungen und andere Ausführungen möglich. The invention is not limited to the example shown, on the contrary, various modifications and other designs are still possible.

So ist es möglich, das ganze Schweißgerät in einen Ständer einzuspannen und das Werkstück darunter wegzuschieben.So it is possible to clamp the whole welding machine in a stand and push the workpiece away from underneath.
