Description

Die Erfindung bezieht sich auf die -'er- ' hindung der leiden Teile einer Schraubeninutter, die aus einem unteren mit kegeliger Ausnehmung versehenen und einem oberen mit hegeligen i Ansatz in diese Ausnehmung eingreifenden Teil hestehr. Bei einer , )ekannten Mutter dieser Art erfolgt die Verbindung der beiden Teile durch Umlegen einer Ringlippe. und zwar ragt die Ringlippe von der oberen Fläche des unteren Mutterteils aus nach oben in eine Ringnut des oberen Mutterteils hinein und «wird heim Anziehen des oberen Teils durch die Wand der Ringnut nach innen gedrückt.The invention relates to the -'er- 'invention of the parts of a screw nut, which consist of a lower part provided with a conical recess and an upper part which engages in this recess with a conical approach. In a,) ekannten nut of this kind the connection of the two parts is effected by moving an annular lip. namely, the annular lip protrudes from the upper surface of the lower nut part upwards into an annular groove in the upper nut part and is pressed inwards through the wall of the annular groove when the upper part is tightened.

Demgegenüber besteht die Erfindung darin. daß die Ringlippe. «wie dies an sich bekannt ist, durch Ein stechen einer Ringnut in die obere Fläche des unteren Mutterteils gebildet ist, und daß das Umlegen der Lippe durch Eindrücken eines Keilringes in die Ringnut erfolgt. der an einer zweiteiligen. in den Zwischenraum zwischen die lfutterteile einschiehharen Blechlehre sitzt. Dies hat den . Vorteil, daß die Herstellung der zweiteiligen Mutter einfacher ist und daß das Umlegen der Lippe zuverlässiger erfolgt.In contrast, the invention consists in this. that the ring lip. "how this is known per se, by pricking an annular groove in the upper surface of the lower nut part is formed, and that folding the lip by pressing a wedge ring takes place in the annular groove. the one on a two-part. in the space A sheet metal jig sits between the chuck parts. This has the. Advantage, that the production of the two-part nut is easier and that the folding Lip is done more reliably.

In der Zeichnung ist der Erfindungsgegenstand leispielsweise dargestellt, und zwar Zeigt Abb. i und 2 den Mutterunterteil in zwei verschiedenen Ausführungen, während Ahb. 3 die Wirkung weise des Keilringe:. darstellt, und Ahb. .i die -Mutter nach Herstellung der Verbindung zeigt.In the drawing, the subject of the invention is shown for example, namely shows Fig. i and 2 the nut base in two different designs, while Ahb. 3 the effect of wedge rings :. represents, and Ahb. .i the mother shows after connection is established.
