Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Schweißvorrichtung nach dem Oberbegriff des Anspruchs 1.The Invention is based on a welding device according to the preamble of claim 1.
Eine
bekannte, in sog. elektrischen Schweißautomaten verwendete Schweißvorrichtung,
wie sie in
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Schweißvorrichtung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass mittels der V-förmigen Führungsnut die Schweißelektrode sehr schnell und toleranzgenau in der Spannvorrichtung positioniert werden kann, womit weitere Vorteile begründet werden. So wird ein einseitiger Abbrand der Schweißelektrode infolge ungenauer Positionierung innerhalb der Spannvorrichtung vermieden und damit die Standzeit der Schweißelektrode deutlich erhöht. Die Rüstzeiten im Schweißautomaten werden verkürzt, da durch die genaue Einspannung der Schweißelektrode in der Spannvorrichtung erstere sehr genau vorpositioniert und in ihrem Vorstehmaß aus dem Halter der Spannvorrichtung vermessen werden kann. Nach Einsetzen der Spannvorrichtung mit darin vorpositionierter Schweißelektrode ist ein Nach- oder Einjustieren der Schweißelektrode während des Betriebs nicht mehr erforderlich. Aufgrund der die Schweißelektrode hochgenau positionierenden Spannvorrichtung sind die Schweißergebnisse in gleicher Qualität reproduzierbar und die Prozessstabilität steigt. Zusätzlich wird auch die Qualität der einzelnen Schweißungen verbessert, und die Ausschussquote sinkt deutlich.The inventive welding device with The features of claim 1 has the advantage that by means of V-shaped guide the welding electrode positioned very quickly and with tolerance in the clamping device which can be used to justify further benefits. So is a one-sided Burning of the welding electrode avoided due to inaccurate positioning within the fixture and thus significantly increases the service life of the welding electrode. The up times in the welding machine be shortened, because of the exact clamping of the welding electrode in the clamping device The former are very precisely prepositioned and in their Vorstehmaß from the Holder of the clamping device can be measured. After insertion the clamping device with pre-positioned welding electrode therein is a readjustment or adjustment of the welding electrode during the Operation no longer required. Due to the welding electrode highly accurate Positioning jig are the welding results in the same quality reproducible and process stability increases. In addition will also the quality the individual welds improved, and the reject rate drops significantly.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Schweißvorrichtung möglich.By in the further claims listed activities are advantageous developments and improvements in the claim 1 specified welding device possible.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist die Schweißelektrode eine Vollelektrode, die vollständig aus Elektrodenverbrauchsmaterial besteht, und weist zwei in Längsachse sich erstreckende Seitenflächen auf, die miteinander einen Winkel einschließen, der an den von den Führungsflächen der Führungsnut im Halter der Spannvorrichtung eingeschlossenen Winkel angepasst ist. Durch die Verwendung einer Vollmaterialelektrode, die ausschließlich aus beim Schweißen abbrennendem Elektrodenmaterial, vorzugsweise aus Wolfram-Lanthan (WL), besteht, ist ein wiederholtes Nachschleifen des beim Schweißen abbrennenden Elektrodenmaterials möglich, womit Kosteneinsparungen für die Schweißelektroden einhergehen. Durch die Einteiligkeit der Vollmaterialelektrode treten – anders als beim Einlöten vom Elektrodenverbrauchsmaterial aus Wolfram-Lanthan in einen Aufnahmeschaft aus Kupfer-Chrom-Zirkonium – keine durch unterschiedliche Lötspalte bedingte Übergangswiderstände auf. Die langgestreckte, einteilige Form der Schweißelektrode ermöglicht auch das Anschleifen von komplexen Elektrodenformen. Die Anpassung des von den Seitenflächen der Vollmaterialelektrode eingeschlossenen Winkels an den zwischen den Führungsflächen des Halters eingeschlossenen Winkel verbessert die Reproduzierbarkeit der Spannposition für die Schweißelektrode im Halter, so dass die Schweißelektrode auch nach einem zum Zwecke des Nachschleifens erfolgtem Herausnehmen der Schleifelektrode aus der Spannvorrichtung beim erneuten Einspannen in die Spannvorrichtung wieder exakt positioniert ist.According to one advantageous embodiment of the Invention is the welding electrode a full electrode that completely consists of electrode consumable material, and has two in the longitudinal axis extending side surfaces on, which enclose an angle with each other, that of the guide surfaces of the guide adjusted in the holder of the tensioner included angle is. By using a solid material electrode made exclusively of when welding Abbrennendem electrode material, preferably of tungsten-lanthanum (WL), is a repeated regrinding of the burning during welding Electrode material possible, with which cost savings for the welding electrodes accompanied. Due to the one-piece nature of the solid material electrode - different as when soldering from the tungsten lanthanum electrode consumable material into a receiving shaft made of copper-chrome-zirconium - no through different soldering gaps conditional contact resistance. The elongated, one-piece shape of the welding electrode also allows the grinding of complex electrode forms. The adaptation of the from the side surfaces the solid material electrode included angle at the between the guide surfaces of the Holder's included angle improves reproducibility the clamping position for the welding electrode in the holder, leaving the welding electrode even after a removal done for the purpose of regrinding the sliding electrode from the clamping device when re-clamping is accurately positioned in the clamping device again.
