Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das elektrische Anschweißen von Eisenstäben auf dünne Bleche ist nach der gewöhnlichen und bekannten Art der elektrischen Stumpfschweißung ausgeschlossen, weil die Schweißquerschnitte zu verschiedenartig sind und deshalb die Schweißhitze nicht gleichmäßig wird.The electrical welding of iron rods on thin sheets is common and known type of electric butt welding excluded because the welding cross-sections are too diverse and therefore the welding heat is not uniform will.

Um dennoch eine derartige Schweißung zu ■ ermöglichen, ist folgende Vorrichtung zweckmäßig angeordnet worden.In order to nevertheless enable such a weld, the following device is expedient has been arranged.

Das Rohr R, welches an das dünne Blech B angeschweißt werden soll, wird in der Kontaktklemme K1 eingespannt und so mit dem Plus-Pol verbunden. Das Blech dagegen wird an die Kontakte Ku durch Federn F F angepreßt und ist so . mit dem Minus-Pol verbunden. Vermittels des Druckstiftes D mit isoliertem Kopf J K wird das Blech an das Rohr angepreßt und so der Kontakt vermittelt. Es geht somit bei Stromschluß dieser durch den Plus-Pol auf das Rohr, von diesem durch das Rohr, von diesem durch das Blech in den Minus-Pol in der Richtung der Pfeile.The tube R, which is to be welded to the thin sheet metal B , is clamped in the contact clamp K 1 and thus connected to the positive pole. The sheet metal, however, is pressed against the contacts K u by springs FF and is like that. connected to the minus pole. By means of the pressure pin D with an insulated head JK , the sheet metal is pressed against the pipe and the contact is made in this way. When there is a current connection, it goes through the plus pole onto the tube, from there through the tube, from there through the sheet metal into the minus pole in the direction of the arrows.

Der Strom bringt Rohr und Blech ins Glühen, jedoch verhindert der Druckkopf J K die. Bildung von Schweißhitze, da der Kopf zu viel Hitze aufnimmt. Sobald gute Glut erreicht ist, so daß Rohr und Blech etwas zusammenhaften, kann der Druckkopf J K vom Blech entfernt werden, und das Blech kommt mit dem Rohr in Schweißhitze. Durch hammerartige Bewegung des Druckkopfes J K an das Blech wird eine innige Verschweißung erzielt.The current causes the tube and sheet metal to glow, but the print head JK prevents this. Build up of sweat, as the head absorbs too much heat. As soon as a good glow has been achieved, so that the pipe and sheet metal stick together somewhat, the print head JK can be removed from the sheet metal, and the sheet metal with the pipe is heated by welding. An intimate weld is achieved by a hammer-like movement of the print head JK on the sheet metal.

Patent-Ansprüche:Patent Claims: 1. Verfahren zum elektrischen Schweißen von Fasson-Rundeisen oder Rohren auf dünne Unterlagen, wie Bleche u. dgl., dadurch gekennzeichnet, daß mittels einer gut wärmeleitenden isolierten Druckvorrichtung '(D) die Schweißenden aneinander gepreßt und so die Schweißung eingeleitet und nach eingeleiteter Schweißung die Druckvorrichtung entfernt wird, worauf während des dann folgenden Schweißprozesses durch stoßweises kurzes Anpressen der Druckvorrichtung an die Schweißstelle letzterer ein. festes Gefüge erteilt wird.1. A method for the electrical welding of Fasson round iron or pipes on thin substrates, such as sheet metal and the like., Characterized in that the weld ends are pressed together by means of a highly thermally conductive insulated pressure device '(D) and so the weld is initiated and after the weld has been initiated the pressure device is removed, whereupon the pressure device is pressed against the welding point during the subsequent welding process by briefly pressing the pressure device against the welding point. fixed structure is granted. 2. Ausführungsform des Verfahrens zum elektrischen Schweißen nach Anspruch I, dadurch gekennzeichnet, daß die Schweißpole (K1 K11J sich nicht genau gegenüberstehen, sondern derart voneinander getrennt sind, daß zwischen dem einen Pol (K11) noch die Druckvorrichtung (D) Platz hat.2. Embodiment of the method for electrical welding according to claim I, characterized in that the welding poles (K 1 K 11 J are not exactly opposite each other, but are separated from each other in such a way that the pressure device (D) between the one pole (K 11) Has space.
