Einrichtung zur Vermeidung des Kurzschlusses von DoppelpolelektrodenrollenDevice to avoid short-circuiting of double-pole electrode rollers

für Rührenschweißmaschinen.for stir welding machines.

Zusatz zum Patent 355755.Addendum to patent 355755.

Patentiert ina Deutschen Reiche vom 23. März 1922 ab. Längste Dauer: 18. März 1939. Patented in a Deutsche Reiche on March 23, 1922. Longest duration: March 18, 1939.

Durch das Patent 355755 ist bei Röhrenschweißmaschinen eine Einrichtung zur Vermeidung des Kurzschlusses der Doppelpolelektrodenrollen unter Schutz gestellt, welche gekennzeichnet ist durch eine umlaufende Schleifscheibe, die in den zwischen den beiden Elektrodenringen am Umfang befindlichen Zwischenraum eingreift.The patent 355755 is used for tube welding machines a device to avoid short-circuiting the double-pole electrode rollers is placed under protection, which is characterized by a rotating grinding wheel that is in between the two Electrode rings on the circumference engages space.

Die vorliegende Erfindung betrifft eine weitere Ausbildung dieser Einrichtung. Es hatThe present invention relates to a further embodiment of this device. It has

sich nämlith gezeigt, daß die in gebräuchlicher Weise hergestellten Schleifscheiben einem schnellen Verschleiß unterworfen sind.It has been shown that the in common Way manufactured grinding wheels are subject to rapid wear.

Dieser Nachteil wird gemäß vorliegender Erfindung dadurch behoben, daß der umlaufende Schleifkörper aus zwei besonders dünnen, voneinander elektrisch isolierten, aus Metall bestehenden Scheiben gebildet wird, die an ihrem Umfang schleifend oder schneidend wirken. Beispielsweise können die Metallscheiben am Umfang nach Art von Kreissägen mit Zähnen versehen sein, so daß durch die schnelle Drehung dieser Schleifoder Schneidvorrichtung der Spalt frei gehalten wird.This disadvantage is eliminated according to the present invention in that the rotating Abrasive body is formed from two particularly thin, electrically insulated metal disks, which have a grinding or cutting effect on their circumference. For example, the metal disks be provided with teeth on the circumference in the manner of circular saws, so that the rapid rotation of this grinding or Cutting device the gap is kept free.

In Abb. ι und 2 der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform veranschaulicht. Abb. 3 zeigt die Schleif- oder Schneidvorrichtung in vergrö-In Fig. Ι and 2 of the drawing, the subject of the invention is illustrated in one embodiment. Fig. 3 shows the Grinding or cutting device in enlarged

ao ßertem Maßstab.on a larger scale.

Bei der gezeichneten Ausführungsform finden zwei ganz dünne kreissägenartige Metallblätter d Anwendung, die voneinander und von den Nabenscheiben g durch Isolierschichten h und i getrennt sind. Auf der Welle k ist eine Büchse I aus Vulkanfiber o. dgl. angebracht, welche die ganze Schleifvorrichtung gegenüber der Welle isoliert. Die beiden Kreissägenblätter d sind mit der zwischenliegenden Isolierung so dünn, daß sie in den Spalt zwischen den beiden Elektrodenrollen σ eingreifen und diesen von Verunreinigungen freihalten.In the embodiment shown, two very thin circular saw-like metal blades d are used, which are separated from one another and from the hub disks g by insulating layers h and i . A sleeve I made of vulcanized fiber or the like is attached to the shaft k and insulates the entire grinding device from the shaft. The two circular saw blades d with the insulation between them are so thin that they engage in the gap between the two electrode rollers σ and keep it free from contamination.
