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.
