Description

Verfahren zur Kunststoff-Spritznietung lamellierter Blechpakete von elektrischen Maschinen und Geräten Es ist bekannt, die lamellierten Blechpakete elektrischer Maschinen oder Geräte dadurch in schneller und billiger Weise zu verbinden, daB man in entsprechende Bohrungen der Bleche thermoplastische Kunststoffe einspritzt, die dann als Niete wirkend die Bleche zusammenhalten.Process for the plastic spray riveting of laminated sheet metal stacks from electrical machines and devices It is known the laminated laminated cores to connect electrical machines or devices in a faster and cheaper way, that thermoplastic plastics are injected into the corresponding holes in the sheet metal, which then act as rivets hold the sheets together.

In weiterer Ausgestaltung eines solchen Verfahrens werden nach der Erfindung vor der Kunststoff-Spritznietung Metallstifte, vorzugsweise vergütete Stahlstifte, in die Nietlöcher eingeführt, die bei der Kunststoffspritzung mit eingespritzt werden und so den Kern der Kunststoffniete bilden. Die Scherfestigkeit der Kunststoffniete wird hierdurch wesentlich erhöht, und es ist nunmehr möglich, die auf diese Weise vernieteten Blechpakete zu bearbeiten, was für den Einbau derselben oder für den Anschluß an Lagerbügeln u. dgl. vielfach erforderlich ist.In a further embodiment of such a method, according to the Invention before the plastic injection riveting metal pins, preferably tempered Steel pins inserted into the rivet holes that are also injected into the plastic injection molding process and thus form the core of the plastic rivet. The shear strength of the plastic rivet is hereby increased significantly, and it is now possible to do so in this way to edit riveted laminations, what for the installation of the same or for the Connection to bearing brackets and the like is often required.

Die Metallstifte können vor der Einführung in die Nietlöcher vorzugsweise phosphatiert und lackiert werden. Als Lack kann dabei ein Isolierlack verwendet werden, damit durch die Einführung der vergüteten Metallstifte keine elektrische Überbrückung der lamellierten Pakete erfolgt.The metal pins can preferably be inserted into the rivet holes be phosphated and painted. An insulating varnish can be used as the varnish so that by introducing the tempered metal pins there is no electrical Bypassing the laminated packages done.
