Description

Es sind Lötvorrichtungen mit Gasbeheizung bekannt, die aus zwei einander umschließenden, den zu lötenden Dosenrumpf zwischen sich aufnehmenden Zylindern bestehen. Bei, diesen Vorrichtungen ist in dem inneren, als Vollkörper ausgeführten Zylinder ein enger Kanal vorgesehen, in den ein die Lötflamme speisendes, mit Brenneröffnungen versehenes Gasrohr frei eingelegt ist. Oben ist der Kanal ίο durch die zu lötende Blechnaht abgedeckt. Bei derartigen Vorrichtungen besteht der Nachteil, daß kein die Lötnaht zusammenpressender Stempel in Anwendung gebracht werden kann, da das Widerlager dafür fehlt. Ferner sind mit Gas beheizte ähnliche Lötvorrichtungen nicht mehr neu, bei denen die Heizflamme unter Vermittlung einer den Kanal nach oben abschließenden Platte auf die Lötstelle einwirkt, die als Widerlager für den so Preßstempel dient. Diese Vorrichtung weist den Nachteil großer Wärmeverluste auf, da die Lötflamme nicht unmittelbar auf die Lötnaht, sondern auf die Widerlagerplatte einwirkt und diese die Wärme an den sie um· gebenden Vollzylinder abgibt.There are known soldering devices with gas heating, which consist of two enclosing, the can body to be soldered exist between receiving cylinders. At, of these devices is a narrow cylinder in the inner cylinder, which is designed as a solid body Channel provided in which a soldering flame feeding, provided with burner openings Gas pipe is freely inserted. At the top, the channel ίο is covered by the sheet metal seam to be soldered. With such devices there is the disadvantage that none of the solder seam compressive Stamp can be brought into use because the abutment is missing. Furthermore, similar soldering devices heated with gas are no longer new where the Heating flame on the soldering point with the help of a plate that closes off the channel at the top acts, which serves as an abutment for the so press ram. This device has the disadvantage of large heat losses, since the soldering flame is not directly on the soldering seam, but acts on the abutment plate and this transfers the heat to which it is giving full cylinder releases.

Die Nachteile der bekannten Vorrichtungen werden durch die den Gegenstand der Erfindung bildende neue Lötvorrichtung vermieden. Die Erfindung besteht darin, daß in dem unter dem Preßstempel liegenden Kanal des Zylinders eine gegen den letzteren isolierte Schiene aus elektrischem Widerstandsstoff eingesetzt ist, an die die Zuleitungen für den elektrischen Heizstrom !unmittelbar angeschlosisen sind.The disadvantages of the known devices are made by the subject of the invention avoiding forming new soldering device. The invention is that in the under the ram lying channel of the cylinder is an insulated from the latter Rail made of electrical resistance material is used to which the supply lines for the electrical heating current! are directly connected.

In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung schematisch dargestellt.In the drawing is an exemplary embodiment of the invention shown schematically.

Ein Zylinder c weist auf seiner oberen Seite gegenüber einem Stempel e einen Kanali? auf, dessen Boden- und Seitenwände mit einer isolierenden Schicht b, z. B. aus Speckstein, bekleidet sind und der eine Schiene c aufnimmt, die aus einem elektrischen Widerstandsstoff, z. B. Chromnickelstahl, besteht. An den Enden dieser Schiene α sind die den elektrischen Strom zuführenden Anschlußkabel befestigt.A cylinder c has a channel on its upper side opposite a punch e? on, the bottom and side walls with an insulating layer b, z. B. made of soapstone, are clothed and which receives a rail c, which is made of an electrical resistance material, for. B. chrome nickel steel. At the ends of this rail α the connecting cables feeding the electrical current are attached.

Während der Zeit, in der sich ein Dosenrumpf auf dem Dorn nicht befindet, tritt infolge des durch die Anschlußkabel zugeführten elektrischen Stromes eine starke Erhitzung der isolierten Schiene α ein, die ihre Wärme unmittelbar von unten an die darüber befindliche und durch den Stempele zusammengepreßte Lötnaht abgibt, wenn eine Dosenzarge mit dem zwischengelegten Lotstreifen aufgeschoben ist. Die Erhitzung der Lötnaht wird dadurch wesentlich gefördert, daß die Ränder der aufgeschobenen Dosenzarge den elektrischen Strom auch noch kurzschließen. Nachteile entstehen durch diesen Kurzschluß nicht, da die Dosenzargen nur einen Augenblick auf dem Dorn verbleiben.During the time in which a can body is not on the mandrel, the electrical current supplied by the connecting cable causes the insulated rail α to heat up, which gives off its heat directly from below to the soldered seam above it which is compressed by the punch when a can frame with the solder strip inserted between them is pushed on. The heating of the solder seam is significantly promoted by the fact that the edges of the pushed-on can body also short-circuit the electrical current. This short circuit does not cause any disadvantages, since the can bodies only remain on the mandrel for a moment.
