Description
Die Erfindung betrifft einen selbsttätigen elektrischen Lichtbogenschweißapparat, der nach dem Verfahren von Bernardos oder Slavianoff arbeitet, d..h., bei dem das Schweißgut entweder dem Lichtbogen besonders zugeführt wird oder bei dem es gleich-• zeitig die Elektrode bildet. Ist bei derartigen Apparaten das meist in Form eines Drahtes oder einer Stange zugeführte Schweißmaterial ίο verbraucht, so tritt eine Störung des Betriebes ein. Bei dem Apparat nach Bernardos erhält· die Schweißstelle nicht genügend Füllmaterial, bei dem Apparat nach Slavianoff reißt der Lichtbogen ab oder es bildet sich ein Lichtbogen an einer anderen unerwünschten Stelle.The invention relates to an automatic electric arc welding apparatus, the works according to the method of Bernardos or Slavianoff, i.e. in which the Welding material is either specially fed to the arc or where it is forms the electrode early. In the case of such devices, this is usually in the form of a wire or welding material fed to a rod ίο is used up, operation will be disrupted a. With the Bernardos apparatus, the weld does not get enough Filling material, in the case of the apparatus according to Slavianoff the arc breaks off or it an arc forms at another undesired location.
Gemäß der Erfindung wird der Schweißapparat mit einer selbsttätigen Vorrichtung zum Unterbrechen des Schweiß stromes versehen, die in Wirkung tritt, kurz bevor der Apparat durch Verbrauch des Schweißdrahtes betriebsunfähig werden würde. Zweckmäßig wird diese Vorrichtung vom Schweißdraht selber gesteuert, wenn sein dem Lichtbogen gegenüberliegendes Ende eine bestimmte Stelle des Apparates durchläuft. Diese Stelle liegt beispielsweise bei Apparaten, die nach dem Verfahren von Slavianoff arbeiten und bei denen ein besonderer Gleitkontakt o. dgl. den elektrischen Strom auf den bewegten Schweißdraht überleitet, vor der Kontaktstelle, damit nicht an der Kontaktstelle selber ein Lichtbogen entstehen kann.According to the invention, the welding machine is provided with an automatic device to interrupt the welding current, which comes into effect shortly before the Apparatus would become inoperable due to the consumption of the welding wire. Appropriate this device is controlled by the welding wire itself when its the arc opposite end passes through a certain point of the apparatus. This place is, for example, in apparatuses that work according to the Slavianoff method and in which a special sliding contact or the like. The electric current on the moving Welding wire passes over in front of the contact point, so not at the contact point itself an arc can occur.
In der Zeichnung ist ein Ausführungsbeispiel scfhematisch dargestellt, und zwar für einen Apparat, der nach dem Verfahren vonIn the drawing, an embodiment is shown schematically, namely for an apparatus which, according to the method of
Slavianoff arbeitet. Es bedeutet 11 die Elektrode, die zugleich das Schweißgut liefert.Slavianoff works. It means 11 die Electrode that also supplies the weld metal.
Sie wird durch eine nicht näher gezeichnete selbsttätige oder von Hand betätigte Vor-Schubvorrichtung 12, 13 dem Abbrand entsprechend vorgeschoben, so daß ein gleichmäßiger Lichtbogen 14 zwischen Elektrodenende and Werkstück 15 besteht. Die Transportrollen 12 und 13 bilden gleichzeitig die Stromzuführung zur Elektrode 11. Gegen das oberhalb der Rolle liegende Ende des Schweißdrahtes wird eine Rolle oder Walze 16, die am Ende einer Schubstange 17 sitzt, durch eine Zugfeder 18 gedruckt. Sobald das Ende des Seihweißdrahtes 11 die Rolle 16 passiert hat, bewegt sich die Schubstange unter dem Einfluß der Feder 18 in der durch den Pfeil angedeuteten Richtung. Dabei wird ein Kontakt 19 unterbrochen, wodurch der Schweißstrom unmittelbar oder mit Hilfe von Schützen o. dgl. ausgeschaltet wird.It is activated by an automatic or manually operated pre-thrust device, not shown in detail 12, 13 advanced according to the burn, so that a more even There is an arc 14 between the end of the electrode and the workpiece 15. The transport rollers 12 and 13 simultaneously form the power supply to the electrode 11. Against that above the end of the welding wire lying on the roll is a roll or roller 16, the seated at the end of a push rod 17, pressed by a tension spring 18. As soon as the end of the sieve welding wire 11 passes the roller 16 the push rod moves under the influence of the spring 18 in the direction indicated by the arrow indicated direction. A contact 19 is interrupted, whereby the welding current Is switched off immediately or with the help of contactors or the like.
