Abstract
Description
Herkömmliche Verfahren zur Verbindung von zwei Aluminium rohren beinhalten das Schweißen (siehe Fig. 4 und 5), das Verschrauben, Verkleben oder den Paßsitz. Durch keines der obengenannten Verfahren können jedoch zwei Rohre fest und schnell miteinander verbunden werden.Conventional methods for connecting two aluminum tubes include welding (see FIGS . 4 and 5), screwing, gluing or a snug fit. However, none of the above methods can be used to connect two pipes firmly and quickly.
Es ist folglich Aufgabe der vorliegenden Erfindung, ein verbessertes Verfahren zur Verbindung von zwei rohrförmigen Aluminiumteilen bereitzustellen, das die obengenannten Män gel beseitigt.It is therefore an object of the present invention improved method for connecting two tubular To provide aluminum parts that the above men gel eliminated.
Diese Aufgabe wird durch ein Verfahren gemäß dem Pa tentanspruch gelöst.This task is accomplished by a procedure according to Pa claim resolved.

Wie es in den Zeichnungen und insbesondere den Fig. 1, 2 und 3 gezeigt ist, umfaßt das erfindungsgemäße Verfahren zur Verbindung von zwei rohrförmigen Aluminiumteilen die Schritte:As shown in the drawings and in particular FIGS. 1, 2 and 3, the method according to the invention for connecting two tubular aluminum parts comprises the steps:
- 1. Einsetzen eines Ringteils 2 aus Eisen in das erste rohrförmige Aluminiumteil 10, wobei sich ein Teil des Ring teils 2 aus Eisen aus dem ersten rohrförmigen Aluminiumteil 10 erstreckt;1. Inserting a ring part 2 made of iron into the first tubular aluminum part 10 , wherein part of the ring part 2 made of iron extends from the first tubular aluminum part 10 ;
- 2. Aufsetzen des zweiten rohrförmigen Aluminiumteils 10 auf den Teil des Ringteils 20 aus Eisen, der sich aus dem rohrförmigen Aluminiumteil 10 erstreckt;2. placing the second tubular aluminum part 10 on the part of the ring part 20 made of iron, which extends from the tubular aluminum part 10 ;
- 3. Erwärmen von einem Paar Formen 30, die eine gerin gere Breite als das Ringteil 2 aus Eisen aufweisen, auf eine Temperatur von 660°C;3. heating a pair of molds 30 , which have a narrower width than the ring part 2 made of iron, to a temperature of 660 ° C .;
- 4. Anbringen der Formen 30 an der Stelle, an der die beiden rohrförmigen Aluminiumteile 10 miteinander verbunden sind, so daß die beiden rohrförmigen Aluminiumteile 10 mit einander verschmelzen.4. Attach the molds 30 at the point at which the two tubular aluminum parts 10 are connected to one another so that the two tubular aluminum parts 10 merge with one another.
Da der Schmelzpunkt von Eisen 1538°C beträgt und höher als der von Aluminium ist (660°C) und die Temperatur der For men 30 660°C beträgt, wird das Ringteil 20 aus Eisen nicht geschmolzen, wenn die beiden rohrförmigen Aluminiumteile miteinander verschweißt werden, wodurch eine Deformation der rohrförmigen Aluminiumteile 10 verhindert wird.Since the melting point of iron is 1538 ° C and higher than that of aluminum (660 ° C) and the temperature of the molds 30 is 660 ° C, the ring part 20 made of iron is not melted when the two tubular aluminum parts are welded together , whereby deformation of the tubular aluminum parts 10 is prevented.
