Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Hartlötverbindung zwischen zwei in beliebigem Winkel zueinander verlaufenden Rohren, von denen das eine an einem Ende so geformt ist,, daß es sich, zweckmäßig unter Einschaltung eines Lötplättchens, an die nicht verformte Außenwand des anderen anpaßt, wobei die zu verbindenden Rohre durch den Durchgang eines Stromes auf Hartlöthitze gebracht werden, der durch einen oder ίο mehrere äußere Klemmbacken bzw. durch eine innere, in das nicht verformte Rohr 'eingeführte Elektrode zugeleitet wird.The invention relates to a device for producing a brazed connection between two in any angle to each other, one end of which is shaped like this, that it is, expediently with the inclusion of a soldering plate, on the non-deformed outer wall of the other adapts, the pipes to be connected by the passage of a stream on Brazing heat are brought by one or ίο several outer clamping jaws or by a inner electrode inserted into the non-deformed tube.

Mittels der Vorrichtung gemäß der Erfindung können einfach und schnell· Rohr verb indungen von sauberem Aussehen ohne Lötgrat od. dgl. hergestellt werden, und zwar dadurch, daß die innere Elektrode aus einem Dorn besteht, welcher eine ringförmige Erhöhung aus leitendem Material trägt, deren Form der Form der Berührungsfläche zwischen den zu verbindenden Rohren entspricht. Die Zeichnung zeigt in Fig. 1 zwei senkrecht zueinander verlaufende, zur gegenseitigen Hartlötverbindung mittels der Vorrichtung gemäß der Erfindung zugerichtete Rohre, während Fig. 2 eine schaubildliche Ansicht eines Ausführungsbeispiels des die innere Elektrode bildenden Domes ist.By means of the device according to the invention, pipe connections can be made easily and quickly Clean appearance without solder burr or the like. Be made, namely by the fact that the inner Electrode consists of a mandrel, which is an annular elevation made of conductive material carries, the shape of which corresponds to the shape of the contact surface between the pipes to be connected. The drawing shows in FIG. 1 two mutually perpendicular brazed connections for mutual brazing pipes prepared by means of the device according to the invention, while FIG. 2 shows a Figure 3 is a perspective view of an embodiment of the dome forming the internal electrode.

Von den miteinander zu verbindenden Rohren 1 und 4 wird das Rohr 1 nach entsprechendem Ausschnitt seines Endes z. B. mittels einer geeigneten Matrize und eines Stempels so aufgeweitet, daß man eine ringförmige Berührungsfläche 3 erhält, welche sich an das Rohr 4 dicht anschmiegt. Es wird nun zwischen die Berührungsfläche 3 und das Rohr 4 ein Lötplättchen 5 aus Messing eingeschoben, worauf man sämtliche Teile mit Hilfe eines oder mehrerer Klemmbacken zusammenhält. Während die äußere Stromzuführung ζ. B-. über die genannten Klemmbacken erfolgt, wird der Strom im Innern des Rohres mit Hilfe des in Fig. 2 gezeigten, die Erfindung bildenden Dornes 6 der Lötstelle zugeleitet. Dieser Dorn ist selbst leitend, und sein Durchmesser ist etwas kleiner als der Innendurchmesser des Rohres 4, in welches der Dorn somit leicht eingeschoben werden kann. Mit der Stromquelle ist der Dorn 6 durch ein elektrisches Kabel 7 verbunden. Der auf dem Dorn 6 befindliche ringförmige Vorsprung 8 muß beim Einführen des Dornes in das Rohr 4 gegenüber der Berührungsfläche zu liegen kommen.Of the pipes 1 and 4 to be connected to one another, the pipe 1 is made according to the corresponding section its end z. B. expanded by means of a suitable die and a punch so that an annular contact surface 3 is obtained which hugs the pipe 4 tightly. It a soldering plate 5 made of brass is now inserted between the contact surface 3 and the tube 4, whereupon all parts are held together with the help of one or more clamping jaws. While the external power supply ζ. B-. takes place via the mentioned jaws, the Flow inside the tube with the aid of the mandrel 6 of the invention which is shown in FIG Solder joint fed. This mandrel is self conductive and its diameter is slightly smaller than that Inner diameter of the tube 4, into which the mandrel can thus be easily inserted. With The mandrel 6 is connected to the power source by an electrical cable 7. The one on the mandrel 6 located annular projection 8 must when inserting the mandrel into the tube 4 opposite the Contact surface come to rest.

Nach Einschalten des Stromes fließt dieser von dem Dorn 6 über dessen Erhöhung 8 durch das Rohr 4, das Lötplättchen 5 und die Berührungsfläche 3 des aufgeweiteten Endes des Rohres 1 hindurch zu der oder den äußeren Klemmvorrichtungen. Durch den vorhandenen Widerstand wird das Lötplättchen 5 zum Schmelzen gebracht und so eine einwandfreie Hartlötverbindung zwischen den Rohren 1 und 4 hergestellt.After switching on the current, it flows from the mandrel 6 via its elevation 8 through the Tube 4, the soldering plate 5 and the contact surface 3 of the flared end of the tube 1 through to the outer clamping device or devices. The existing resistance will the soldering plate 5 brought to melt and so a perfect brazed connection between the Tubes 1 and 4 produced.

Die Vorrichtung gemäß der Erfindung hat sich besonders bei der Herstellung von Fahrradrahmen gut bewährt. Gegebenenfalls kann der Dorn 6 so ausgestaltet sein, daß in einem einzigen Arbeitsgang mehrere einen Winkel miteinander bildende Rohre durch Hartlötung vereinigt werden können.The device according to the invention has proven particularly useful in the manufacture of bicycle frames well proven. If necessary, the mandrel 6 can be designed so that in a single operation several tubes forming an angle with one another can be joined by brazing.
