Description

Die Erfindung betrifft Elektrodenhalter mit all Backen befestigten Elektroden zur Herstellung von Hartlöt- oder Schweißverbindungen. Gemäß der Erfindung sind die Elektroden bzw. Backen schnabelförmig ausgebildet und nahe dem Schnabelansatz künstlich, z. B. durch Wasser, gekühlt. Dabei gestattet -die Schnabelform das Heranbringen der Elektroden selbst an Verbindungsstellen, um welche wenig freier Raum vorhanden ist. Da; darüber hinaus gemäß der Erfindung die Backen bzw. die Elektroden nahe dem Schnabelansatz künstlich gekühlt werden, tritt an dieser Stelle die sonst wegen der starken Verkleinerung des Querschnitts zu erwartende Erhitzung bzw. Zerstörung durch den durchgehenden Löt- oder Schweißstrom nicht auf.The invention relates to electrode holders with all jaws attached Electrodes for making brazed or welded connections. According to the invention the electrodes or jaws are beak-shaped and close to the base of the beak artificial, e.g. B. by water, cooled. The shape of the beak allows it to be brought closer of the electrodes themselves at connection points around which little free space is available is. There; moreover, according to the invention, the jaws or the electrodes are close the beak base are artificially cooled, occurs at this point because of the significant reduction in the cross-section, the expected heating or destruction due to the continuous soldering or welding current.

In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Hierbei zeigen die Fig. i und 2 eine aus zwei Kupferhebeln i und 2 gebildete Zange, deren Kabelanschlüsse mit 3 und 4 bezeichnet sind. Die Kupferhebel sind über den harten Isolierstoffzylinder 5 gegeneinander isoliert abgestützt. Außerdem umgibt eine tasche 6 unter Zwischenschaltung einer Isolation 7 die beiden Hebel, die in Verbindung mit dem aus festem Isolierstoff, z. B. Hartgewebe, bestehenden Klemmhebel 8 zum Zusammendrücken der Backen 9 und io der Hebel i und 2 dient. Gemäß der Erfindung sind die Backen am vorderen Ende schnabelförmig ausgebildet. An diesen Enden sind die Kohleelektroden ii und i2 befestigt. Außerdem werden die Backen möglichst nahe den Schnabelansätzen durch Wasser gekühlt, das über die Rohrleitungen 13 und 14 den Backen zugeführt wird. Während im vorliegenden F;11 das Kühlmittel beiden Backen von unten zugeführt wird, zeigen die Fig. 3 und q. in einen Elektrodenhalter einzuspannende Elektrodenträger 15 und 16, deren schnabelförmigen Teilen 17 und 18 das Kühlwasser in einem Fall von oben, im anderen Fall von unten zugeführt wird. Zu diesemZweck sind für,den oberen schnabelförmigen Teil 17 die Kühlmittelführungen i9, für den unteren die Kühlmittelführungen 2o vorgesehen. Um ein besonders gutes Herankommen auch bei äußerst beschränkten Raumverhältnissen zu ermöglichen; sind die schnabelförmigen Teile nahe den Elektroden an .den Stellen 21 und 22 besonders stark geschwächt.Exemplary embodiments of the invention are shown in the drawing. Here, FIGS. I and 2 show a pair of pliers formed from two copper levers i and 2, whose cable connections are designated by 3 and 4. The copper levers are over the hard insulating cylinder 5 supported against each other insulated. Also surrounds a pocket 6 with the interposition of an insulation 7 the two levers that are in Connection with the solid insulating material, e.g. B. hard tissue, existing clamping lever 8 to compress the jaws 9 and io the lever i and 2 is used. According to the invention the jaws are beak-shaped at the front end. At these ends are the carbon electrodes ii and i2 attached. In addition, the jaws are as close as possible the beak necks are cooled by water that flows through the pipes 13 and 14 is fed to the jaws. While in the present F; 11 the coolant is used in both jaws is fed from below, FIGS. 3 and q show. to be clamped in an electrode holder Electrode carriers 15 and 16, the beak-shaped parts 17 and 18 of which are the cooling water in one case from above, in the other case from below. To this end are for, the upper beak-shaped part 17, the coolant guides i9, for the the lower the coolant ducts 2o provided. For a particularly good approach to enable even with extremely limited space; are the beak-shaped ones Parts near the electrodes at. The points 21 and 22 are particularly weakened.
