Description

Schweißstromzuführung zu den Wellen von Rollennaht-Widerstandsschweißmaschinen Die Erfindung betrifft eine Stromzuführung zu den Wellen von Rollennaht-Widerstandsschweißmaschinen über zwei federnd angepreßte, den Wellenumfang weitgehend umfassende Kontaktbacken. Für einen einwandfreien störungslosen Stromübergang zwischen den Kontaktstücken und der Welle ist eine entsprechende Beweglichkeit der Backen notwendig, die eine jeweils flächige Anlage gewährleistet. Deshalb erfolgte bisher der Stromanschluß der Backen über flexible Kabelbänder.Welding power supply to the shafts of roller seam resistance welding machines The invention relates to a power supply to the shafts of roller seam resistance welding machines via two resiliently pressed contact jaws that largely encompass the circumference of the shaft. For a flawless, trouble-free current transfer between the contact pieces and the shaft a corresponding mobility of the jaws is necessary, the one in each case a two-dimensional system is guaranteed. This is why the power connection has been made so far the jaws via flexible cable ties.

Der Erfindung liegt die Erkenntnis zugrunde, daß diese Kabelbänder wenig zweckdienlich sind, weil sie zwecks Erzielung eines ausreichenden Querschnitts sehr stark bemessen werden müssen, was viel Platz einnimmt und die Unterbringung in einem Gehäuse erschwert sowie ihnen eine Steifigkeit gibt, die einer glatten Anschmiegung der Kontaktflächen an der Welle hinderlich ist.The invention is based on the knowledge that these cable straps are not very useful because they are in order to achieve a sufficient cross-section have to be dimensioned very large, which takes up a lot of space and the accommodation difficult in a housing and gives them a rigidity that a smooth one Nestling of the contact surfaces on the shaft is a hindrance.

Demgegenüber bringt die Erfindung eine erhebliche Verbesserung. Die Erfindung besteht darin, daß die beiden Kontaktbacken in an sich bekannter Weise als mit gefederten Bolzen miteinander verbundene zweiarmige Hebel ausgeführt sind, an deren der Welle abgewandten Enden je ein balliges Silberkontaktstück angeordnet ist, und daß zwischen diesen balligen Kontaktstücken eine feste Stromzuführungsschiene mit flachen Silberkontaktstücken liegt.In contrast, the invention brings about a considerable improvement. the Invention consists in that the two contact jaws in a known manner are designed as two-armed levers connected to one another with spring-loaded bolts, at the ends facing away from the shaft a convex silver contact piece is arranged is, and that a fixed power supply rail between these spherical contact pieces with flat silver contact pieces.

Diese Anordnung sichert die Beweglichkeit der Kontaktgabe an der Welle und gestattet zugleich infolge ihrer Materialbeschaffenheit einen sehr guten Stromübergang. Die etwa auftretende Erwärmung läßt sich in an sich bekannter Weise durch Wasserkühlung der Stromzuführungsschiene und der Kontaktbacken niedrig halten. Die unteren Enden der Kontaktbacken können in einem Ölbad liegen, das durch die Wasserkühlung der Kontaktbacken mitgekühlt wird. Das Öl ist derart ausgewählt, daß es mit einem sehr dünnen Film einen möglichst geringen Stromwiderstand an der Wellenkontaktberührung hervorruft.This arrangement ensures the mobility of the contact on the shaft and at the same time allows very good current transfer due to its material properties. Any heating that occurs can be reduced in a manner known per se by water cooling keep the power supply rail and the contact jaws low. The lower ends the contact jaws can lie in an oil bath that is cooled by the water Contact baking is also cooled. The oil is chosen so that it is very easy to use thin film the lowest possible current resistance at the shaft contact contact evokes.

Ein Ausführungsbeispiel der Erfmdung ist in der Zeichnung schematisch dargestellt. Es zeigt Fig. 1 eine Ansicht, teilweise im Schnitt, quer zur Welle, Fig. 2 eine Seitenansicht zu Fig. 1.An embodiment of the invention is shown schematically in the drawing shown. It shows Fig. 1 a view, partly in section, transverse to the shaft, FIG. 2 shows a side view of FIG. 1.

An der die Schweißrolle tragenden Welle 1 liegt rechts und links je eine Silberkontaktschale 2 an, die in Kontaktbacken 3 gehalten sind. Diese Kontaktbacken haben Arme 3', an denen sich gegenüberstehende ballige Silberkontakte 4 vorgesehen sind. Zwischen ihnen liegt eine feste Stromzuführungsschiene 5 mit ebenen Silberkontaktflächen 6. Ein Zugbolzen 7 überträgt die Kräfte der Federn 8 auf beide Backen 3 gleichmäßig und läßt dadurch die Kontakte 1/2 und 4/6 paßgerecht aneinanderliegen. Die Kontaktschiene 5 hat eine Wasserkühlung 9, ebenso die Kontaktbacken 3 eine Wasserkühlung 10 mit Zulauf 11, Schlauchverbindung 12 und Ablauf 13. 14 ist der Ölspiegel eines in einem nicht gezeichneten Gehäuse befindlichen Ölbades.On the shaft 1 carrying the welding roller there is each left and right a silver contact shell 2, which are held in contact jaws 3. These contact jaws have arms 3 'on which opposing convex silver contacts 4 are provided are. A fixed power supply rail 5 with flat silver contact surfaces is located between them 6. A tie bolt 7 transmits the forces of the springs 8 to both jaws 3 evenly and thereby allows the contacts 1/2 and 4/6 to fit against one another. The contact rail 5 has a water cooling system 9, likewise the contact jaws 3 a water cooling system 10 Inlet 11, hose connection 12 and outlet 13. 14 is the oil level in one not shown housing located oil bath.
