Description
In der Patentschrift 523 462 ist eine Vorrichtung zum Löten der Längsnähte von Blechgefäßen, z. B. Konservendosen, mittels eines an die Sekundärwicklung eines Transformators fest angeschlossenen Lötkolbens beschrieben, ' bei der die Sekundärwindung mit dem Lötkolben gegenüber dem festliegenden Transformator verschiebbar ist, ohne daß die Wirkung des Transformators auf sie dadurch unterbrochen wird. Bei dieser Vorrichtung ist der Lötkolben starr ausgeführt.. Das hat den Nachteil, daß sich der Lötkolben bei seiner Erhitzung ausdehnt und nach oben oder unten durchbiegt, so daß er beim Herabdrücken auf die Lötnaht nicht in seiner ganzen Länge glatt aufliegt und an einigen Stellen unwirksam bleibt.In the patent specification 523 462 a device for soldering the longitudinal seams of sheet metal vessels, z. B. food cans, by means of a to the secondary winding of a transformer firmly connected soldering iron described, 'in which the secondary winding with the soldering iron relative to the fixed transformer can be moved without the effect of the transformer on them is interrupted. In this device is the The soldering iron is rigid. This has the disadvantage that the soldering iron becomes too hot when it is heated expands and bends up or down, so that when pressed down on the soldered seam does not lie flat over its entire length and remains ineffective in some places.
Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß der stromleitend in die Sekundärwindung eingeschaltete Lötkolben nachgiebig ausgebildet ist und daß eine heb- und senkbare Unterstützungsschiene vorgesehen ist, die den Lötkolben auf die Lötnaht aufpreßt.This disadvantage is avoided according to the invention in that the electrically conductive in the secondary winding switched on soldering iron is flexible and that a lifting and lowerable support rail is provided which presses the soldering iron onto the soldering seam.
In der Zeichnung ist eine als BeispielIn the drawing is one as an example
dienende .Ausführungsform der Erfindung dargestellt. Serving. Embodiment of the invention shown.
In die aus einem breiten Kupferband bestehende, durch einen Antrieb herabbewegbare Sekundärwindung e eines Transformators ist ein als Lötkolben dienender Lötbügel f mittels Schraubenbolzen r und Muttern r1 stromleitend eingeschaltet. Dieser Lötbügel f umgibt eine an einer heb- und senkbaren Stange o1 angeordnete Unterstützungsschiene 0 in einem gewissen Abstand. Diese Unterstützungsschiene ist außerdem von der Sekundärwindung e und dem Lötbügel f durch eine auf ihr angeordnete Zwischenlage u strom- und wärmeisolierend getrennt. Der Lötbügel /"ist so schwach bemessen, daß' er sich unter dem Druck der herabzubewegenden Unterstützungsschiene 0 glatt auf eine Unterlage, nämlich die Lötnaht, pressen läßt. Wird der Lötbügel f unter dem Einfluß des durch die Sekundärwindung 0 fließenden elektrischen Stromes erhitzt, _sp kann er sich ohne ■Nachteil für den Lötvorgang ausdehnen und werfen, da er während der Lötung selbst durch die Unterstützungsschiene 0 in seiner ganzen Länge anschmiegend auf die Lötnaht aufgepreßt wird. 1 In the secondary winding e of a transformer, which consists of a wide copper strip and can be moved down by a drive , a soldering bow f serving as a soldering iron is switched on to conduct electricity by means of screw bolts r and nuts r 1 . This soldering bracket f surrounds a support rail 0, which is arranged on a rod o 1 that can be raised and lowered, at a certain distance. This support rail is also separated from the secondary turn e and the soldering bow f by an intermediate layer u arranged on it in a current- and heat-insulating manner. The soldering clip / "is so weak that 'it can be pressed smoothly onto a base, namely the soldering seam, under the pressure of the support rail 0 to be moved down. If the soldering clip f is heated under the influence of the electric current flowing through the secondary winding 0, _sp he can expand without ■ disadvantage for the soldering process and throw as it is pressed during the soldering itself through the support rail 0 for its entire length clinging to the solder joint. 1
Die Erfindung bietet den weiteren Vorteil, daß der Querschnitt des Lötbügels f viel schwächer ausgeführt werden kann als bei der bekannten Vorrichtung, so daß zu seiner Erhitzung wesentlich weniger elektrische Energie erforderlich ist.The invention offers the further advantage that the cross-section of the soldering clip f can be made much weaker than in the known device, so that significantly less electrical energy is required to heat it.
