Description
Verfahren zur Herstellung von Spreugringen und nach dem Verfahren hergestellter Sprengring. Gegenstand vorliegender Erfindung ist 2n ein Verfahren zur Herstellung von gesehlitz- en ten Sprengringen, deren Innen- und Aussen rand zueinander konzentrisch liegen.
Man kann die Sprengringe an ihrem In nen- oder Aussenrand mit Aussparungen ver sehen, die mit vom Schlitz des Ringes wach sender Entfernun- immer kleiner werden. Das hat den Vorteil, dass sie sowohl als Innen- als auch als Aussensprengring verwendet wer den können.
Das Verfahren gemäss der Erfindung zur Herstellung von Ringen, deren Innen- Lind Aussenrand zueinander konzentrisch liegen, ist dadurch -ekennzeiehnet, dass man aus einem Arbeitsstück in einem Arbeitsgang n mindestens zwei zueinander konzentriseh lie gende Sprengringe herausstanzt, wobei die Trennfuge vwisehen beiden Ringen wenigstens teilweise gleichzeitig den Aussenrand des innern und den Innenrand des äussern Rin ges bildet.
An Hand beiliegender Zeichnung ist bei spielsweise eine Ausführungsform des Verfah rens erläutert, bei welcher in einem Arbeits gang zwei Sprengringe hergestellt werden.
ZD #n Fig. <B>1</B> zeigt die beiden in einem Arbeits gang herausgestanzten Ringe in Draufsicht" während sie noch konzentrisch zueinander liegen, FinG. 2 und <B>3</B> zeigen die beiden Ringe von einander getrennt, und zwar Fig. 2 den klei neren und Fig. <B>3</B> den grösseren.
Fig. <B>1</B> zeigt die beiden Ringe<B>1</B> und 2 in C, ihrer konzentrischen Lage, in welcher sie sich unmittelbar nach dem Stanzvorgang befin den, durch welchen sie aus einem nicht dar gestellten Arbeitsstück gewonnen wurden. Diese Sprengringe haben zueinander konzen trischen Innen- und Aussenrand. Die Trenn fuge<B>3</B> zwischen den beiden Ringen<B>1</B> und 2 bildet gleichzeitig den Aussenrand des innern Ringes<B>29</B> und den Innenrand des äussern Rin ges<B>1.</B> Im gleichen Arbeitsgang sind mit der Trenn.fuge als Mittellinie und vom Schlitz 4 der Ringe weg schrittweise kleiner werdende, <B>b</B><I>In</I> kreisrunde Löcher<B>5</B> ausgestanzt.
Diese Löcher ergeben, wie die Fig. 2 und<B>3</B> zeigen, mit n #n waehsendem. Abstand vom Schlitz 4 immer kleiner werdende, halbkreisförmige Ausspa- Z, rungen <B>6.</B> Die Grösse dieser Aussparungen ist so gewählt, dass die Ringe in allen Ausspa- run-en -leiche Biegefestigkeit haben. Jeder <B>kn</B> tn <B>C</B> der beiden Ringe<B>1</B> und 2 kann somit sowohl als Aussen- als auch als Innensprengring ver wendet werden.
Die Löcher<B>5</B> brauchen nicht kreisförmig züi sein, das heisst die Aussparungen<B>6</B> könn ten auch andere als Halbkreisform haben. Endlich könnte man den kleineren Ring innen anstatt aussen und den grösseren Ring aussen <B>C</B> anstatt innen mit Ausspar-Lingen versehen oder solche gar an beiden Rändern vorsehen.
Es könnten schliesslich auch mehr als zwei Sprengringe auf einmal aus einem Arbeits stück herausgestanzt werden, wobei dann alle diese Sprengringe zueinander konzentrisch lägen.
Process for the production of snap rings and snap ring produced by the process. The subject matter of the present invention is a method for the production of seated snap rings, the inner and outer edges of which are concentric to one another.
The snap rings can be seen with recesses on their inner or outer edge, which become smaller and smaller with increasing distance from the slot in the ring. This has the advantage that they can be used both as an inner and an outer snap ring.
The method according to the invention for the production of rings, the inner and outer edges of which are concentric to one another, is characterized in that at least two concentric snap rings are punched out of a workpiece in one operation, the parting line at least partially from the two rings at the same time forms the outer edge of the inner and the inner edge of the outer ring.
With reference to the accompanying drawing, an embodiment of the procedural rens is explained, for example, in which two circlips are made in one work gear.
ZD #n Fig. <B> 1 </B> shows the two rings punched out in one operation in a plan view "while they are still concentric to one another, FinG. 2 and <B> 3 </B> show the two rings from one another separately, namely Fig. 2 the smaller one and Fig. 3 the larger one.
Fig. <B> 1 </B> shows the two rings <B> 1 </B> and 2 in C, their concentric position in which they are located immediately after the punching process, through which they are made from a non-represent Work piece were won. These snap rings have concentric inner and outer edges. The parting line <B> 3 </B> between the two rings <B> 1 </B> and 2 simultaneously forms the outer edge of the inner ring <B> 29 </B> and the inner edge of the outer ring <B> 1. </B> In the same work step, <B>b</B> <I> In </I> circular holes <B> 5 are gradually decreasing with the separating joint as the center line and away from the slot 4 of the rings </B> punched out.
As shown in FIGS. 2 and 3, these holes result in n #n increasing. Distance from the slot 4, semicircular recesses, which are becoming smaller and smaller, <B> 6. </B> The size of these recesses is selected so that the rings have the same flexural strength in all the recesses. Each <B> kn </B> tn <B> C </B> of the two rings <B> 1 </B> and 2 can thus be used both as an outer and an inner snap ring.
The holes <B> 5 </B> do not need to be circular, that is to say the recesses <B> 6 </B> could also have a shape other than a semicircle. Finally, the smaller ring could be provided with cut-outs on the inside instead of the outside and the larger ring on the outside <B> C </B> instead of the inside, or even provide them on both edges.
Finally, more than two snap rings could be punched out of a work piece at once, in which case all these snap rings would be concentric with one another.
