Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Beim Schweißen langer Nähte ist es wesentlich, von der Bedienung möglichst unabhängig zu sein, um die Leistung der Maschine zu erhöhen und Fehlschweißungen hintanzuhalten. When welding long seams, it is essential to be as independent as possible from the operator to increase the performance of the machine and prevent faulty welds.

Die im Patent 300536' beschriebene Einrichtung nimmt eine von Hand zu betätigende Punktschweißvorrichtung mit einem Schweißstift an. Der Arbeiter muß für jeden Schweißpunkt einen Hebel bedienen, muß den Strom mittels eines Hand- oder Fußschalters ein- und ausschalten und darf dabei die Rücksichten nicht außer acht lassen, welche dem rechtzeitigen Ein- und Ausschalten zur Vermeldung des Spritzens und Verbrennens der Schweißstelle zukommen. Nach jedem Schweißpunkt ist die Schweißvorrichtung an einer Spindel vorwärts zu bewegen. Nicht unerwähnt sollen auch die bei schnellem Schweißen rasch aufeinanderfolgenden Stromstöße infolge der jedesmaligen Stromuriterbrechung bleiben, welche den Anschluß solcher Maschinen an ein Stromnetz oft unmöglich machen.
Um die Schweißung der Punkte auf der ganzen Länge zwischen den beiden Transformatoren selbsttätig und ohne Stromunterbrechung vornehmen zu können, wird, wie in der Figur dargestellt, eine an sich bekannte, mit einem Kranz aus Elektrodenstiften versehene Schweißrolle angewendet, welche mittels der Spindel des Apparates gleichmäßig an der Naht entlanggeführt wird.The device described in patent 300536 'adopts a hand operated spot welder with a welding pin. The worker must operate a lever for each welding point, must switch the current on and off by means of a hand or foot switch and must not ignore the considerations that must be taken to switch it on and off in good time to prevent splashing and burning of the welding point. After each welding point, the welding device must be moved forward on a spindle. The current surges that follow each other in rapid succession during rapid welding should not go unmentioned as a result of the current interruption, which often makes it impossible to connect such machines to a power network.
In order to be able to weld the points over the entire length between the two transformers automatically and without interrupting the power supply, a known welding roller, provided with a ring of electrode pins, is used, as shown in the figure is guided along the seam.

Sobald ein Stift die Blechüberlappung berührt, beginnt hierbei, wie bekannt, der Stromübergang und die Schweißung, welche so lange anhält, bis durch die Drehung der Rolle der nächste Stift in genau feststellbarer Entfernung daran kommt. Diese Drehung der Stiftrolle ergibt sich von selbst mit fortschreitender Bewegung der Vorrichtung an der Spindel infolge des Druckes der Stifte auf die Schweißstelle. Da bei Berührung eines Stiftes mit der Naht der vorhergehende Stift auch noch mit dieser in Berührung ist, erfolgt kein Schließungsfunke, und da beim Abheben des vorhergehenden Stiftes von der Naht der folgende bereits feste Berührung mit der Naht hat, erfolgt kein Öffnungsfunke. Spritzen und damit zusammenhängendes Verbrennen sind also ohne Betätigung eines Schalters ausgeschlossen, der Strom wird nie unterbrochen.As is known, the current transfer begins as soon as a pin touches the sheet metal overlap and the weld, which lasts until the rotation of the roller of the next pin comes at a precisely determinable distance. This rotation of the pen roll arises automatically as the movement of the device on the spindle progresses as a result of the pressure of the pins on the weld. Because when you touch a pen with the seam the previous pin is still in contact with this, there is no Closing spark, and there, when the previous pin is lifted from the seam, the next one already has firm contact with the seam, there is no opening spark. Splashing and related burning are therefore excluded without actuating a switch, the power is never interrupted.
