Description

Die Erfindung bezieht sich auf ein Verfahren zum Verbinden von zu Paketen geschichteten Blechen für elektrische Geräte mittels Schweißen. Es ist bekannt, die Bleche von Ständern elektrischer Maschinen dadurch miteinander zu verbinden; daß am Umfang des Blechlamellenpa'kets quer zu den Rändern der Bleche steife Eisenstäbe aufgelegt und auf ihrer ganzen Länge mit dem Paket durch elektrische Lichtbogenschweißung verbunden werden. Diese Art der Schweißung erfordert große-, teure Einrichtungen und' eignet sich nicht für die Fließbandfertigung.The invention relates to a method for connecting to Packs of layered sheets for electrical equipment by means of welding. It is known, thereby connecting the sheets of stands of electrical machines to one another; that on the circumference of the Blechlamellenpa'kets across to the edges of the sheets stiff iron rods placed and along its entire length with the package by electric arc welding get connected. This type of weld requires large, expensive equipment and 'is not suitable for assembly line production.

Der Anwendung der Stumpf- oder Abbrenli= schw,eißung in der Weise, daß jeder Eisenstab auf seiner ganzen Länge gleichzeitig mit allen Blechen des Paketes verschweißt wird, steht entgegen, daß eine feste Verbindung des Stabes mit allen Blechen dabei nicht sicher gewährleistet-ist, weil der Widerstand zwischen dem Stab und-deri einzelriei Blechen naturgemäß verschieden groß sein und daher die Stromverteilung auf die einzelnen Bleche starke Unterschiede aufweisen müßte. Abgesehen davon wären für diese Schweißungen außerordentlich große Ströme und entsprechend große Stromerzeugeranlagen notwendig.The application of the stump or abbrenli = blackness in such a way that that every iron rod along its entire length simultaneously with all the sheets of the package is welded, opposes that a firm connection of the rod with all Sheet metal is not reliably guaranteed because of the resistance between the rod and the individual metal sheets naturally differ in size and therefore the power distribution on the individual sheets would have to show strong differences. Apart from that, would be for these welds extremely large currents and correspondingly large power generating systems necessary.

Die angeführten Nachteile werden gemäß der Erfindung dadurch vermieden, daß die Bleche des Paketes nacheinander durch Punkt- bzw. Nahtschweißung mit jedem der aus nachgiebigen Blechstreifen bestehenden Metallstücke verbunden werden.The stated disadvantages are avoided according to the invention by that the sheets of the package one after the other by spot or seam welding with each the metal pieces consisting of flexible sheet metal strips are connected.

In der Zeichnung ist schematisch eine Schweißvorrichtung für ein Blechpaket dargestellt. Darin ist mit io ein Schweißgenerator und mit i i ein Blechpaket bezeichnet, dessen Bleche 12 in vergrößertem Maßstab gezeichnet durch Aufschweißen eines Blechstreifens 13 zusammengehalten werden sollen. Ein Pol des Generators ist mit dem Blechpaket verbunden, das zweckmäßig in ein Quecksilberbad 14 gesetzt ist, um eine gute elektrische "Verbindung sämtlicher Bleche mit dem einen Generatorpol zu erhalten. Der andere Pol ist mit einer Rolle 15 verbunden, die während des Schweißens unter Druck auf dem Blechstreifen entlang geführt wird,"Beim Abrollen der Rolle wird nacheinander Blech um Blech mit dem Blechstreifen verschweißt. Das beschriebene Verfahren ergibt eine zuverlässige Verbindung aller Bleche mit dem Blechstreifen und ist mit geringem Aufwand durchführbar.In the drawing, a welding device for a laminated core is schematically shown. A welding generator is denoted by io and a laminated core is denoted by i i, its sheets 12 drawn on an enlarged scale by welding a sheet metal strip 13 should be held together. One pole of the generator is with the laminated core connected, which is expediently placed in a mercury bath 14 to ensure a good electrical "To keep all metal sheets connected to one generator pole. The other Pole is connected to a roller 15, which is under pressure during welding is guided along the sheet metal strip, "When unrolling the roll is one after the other Sheet to sheet welded to the sheet metal strip. The procedure described yields a reliable connection of all sheets with the sheet metal strip and is with little Effort feasible.
