Spa&idigr;düngen, den 04.12.39 Befestigung von Elektroden in einem ElektrodenschaftSpa&idigr;düngen, 04.12.39 Attaching electrodes in an electrode shaft

Hiermit melde ich volgende Neuerung als GeLrdUChsnvister an:I hereby report the following innovation as a GeLrdUCHsnvister:

Die Neuerung betrifft die Befestigung von Elektroden aus Kupferlegierung in einem Stahlschaft·The innovation concerns the fastening of copper alloy electrodes in a steel shaft·

Bisher wurde die Befestigung durch Einlöten der aus einer Kupferlegierung bestehende Elektrode in den Stahlschaft vorgenommen, üie Vorbereitungsarbeiten, wie Säubern von Aufnahmeschaft, Säubern der Elektrode, Aufbringen von Flußmittel sowie zusätzliche Materialien wie Flußmittel und Lötzinn verteuern die Herstellung. Der zusätzliche Zeitaufwand für diese Arbeiten schlägt weiterhin als Verteuerung der Her stellung zu Buche.Until now, the attachment was carried out by soldering the electrode, which is made of a copper alloy, into the steel shaft. The preparatory work, such as cleaning the holder shaft, cleaning the electrode, applying flux and additional materials such as flux and solder, made production more expensive. The additional time required for this work also increased the cost of production.

Der Neuerung liegt die Aufgabe zugrunde, schneller und damit kosten sparender zum gleichen Ergebnis zu kommen; nämlich die Elektrode sicher zu kontaktieren und fest im Elektrodenschaft zu halten.The innovation is based on the task of achieving the same result more quickly and thus more cost-effectively; namely, to contact the electrode securely and hold it firmly in the electrode shaft.

Zur Lösung der Aufgabe wird vorgeschlagen, die Elektrode in eine Bohrung des Elektrodenschaftes einzupressen. Der Einpressvorgang erfolgt zweck mäßiger Weise mittels einer Spindelpresse.To solve the problem, it is proposed to press the electrode into a hole in the electrode shaft. The pressing process is conveniently carried out using a screw press.

Die Neuerung wird anhand einer Zeichnung näher erläutert: siehe Anlage.The innovation is explained in more detail using a drawing: see attachment.

Befestigung von Elektroden in einem Elektrodenschaft BlattFixing of electrodes in an electrode shaft sheet

Bisher wurde in einem Elektrodenhalter (1) eine Bohrung (3) eingebracht, die größer als der Durchmesser der Elektrode (2) war. In den Zwischen -raum (4) wurde Lötzinn eingebracht, das der Elektrode (2) einen festen Sitz gibt und die Möglichkeit guter elektrischer Leitfähigkeit zwischen Hal tar (H und Elektrode (2).Previously, a hole (3) was made in an electrode holder (1) that was larger than the diameter of the electrode (2). Solder was placed in the space (4) to give the electrode (2) a firm seat and enable good electrical conductivity between the holder (H) and the electrode (2).

Diese Verfahrensweise war aufwendig und zeitintensiv.This procedure was complex and time-consuming.

Die Neuerung zeigt dagegen ein Verfahren, das unter Einsparung von Löt -mitteln und Zeit den gleichen Effekt erreicht. Dabei wird die Bohrung (3) so gewählt, daß die einzuführende Elektrode (2) mit Preßsitz in der Bohrung sitzt.The innovation, however, shows a process that achieves the same effect while saving solder and time. The hole (3) is selected so that the electrode (2) to be inserted sits in the hole with a press fit.

Der Preßsitz wird mittels Druck, z.B. durch eine Spindelpresse erreicht.The press fit is achieved by means of pressure, e.g. using a screw press. Es entfallen damit die Arbeitsgänge:This eliminates the following work steps: Lötmittel und Flußmittel eingeben, Elektrode säubern, Löten, wiederumAdd solder and flux, clean electrode, solder, again

Säubern.Clean.
