Description
Die Erfindung bezieht sich auf eine Vorrichtung gemäß dem Oberbegriff des Patentanspruches.The invention relates to a device according to the preamble of the claim.
In der gattungsbildenden DE-PS 35 39 835 wird eine Spalt-/Stauchrolle beschrieben, mit der angestrebt wird, daß beiderseits des Mittelteils einer Ronde zwei senkrecht zum Mittelteil stehende Flansche ausgeformt werden, die in ihrer Gesamtheit eine größere Wandstärke als das Mittelteil aufweisen, wobei aber ein Auswandern der Ronde während des Verformungsvorganges, ein Einknicken oder ein Reißen des gebildeten zylindrischen Teils mit Si cherheit ausgeschaltet wird. Mit dieser bekannten Vorrichtung wird im mitteleren Teil der Ronde immer eine durch die Schneidspitze bedingte Einpressung erzielt, so daß beim Herstellen einer Poly-V-Schei be immer im mittleren Bereich der zylindrischen Auflagefläche eine Vertiefung sein muß, da sonst hier eine durch die Schneidspitze bedingte Schwä chung und Materialbeeinflussung vorliegt.In the generic DE-PS 35 39 835 is a Split / compression roller described, with the desired will that on either side of the central part of a round blank two flanges perpendicular to the middle section are formed, which in their entirety is a have a greater wall thickness than the central part, but a migration of the round blank during the Deformation process, a buckling or a Tear the formed cylindrical part with Si security is turned off. With this known Device is always in the central part of the round blank an injection caused by the cutting tip achieved so that when producing a poly-V Schei be always in the middle of the cylindrical Contact surface must be a recess, otherwise here a Schwa caused by the cutting tip and material influencing.
Aus der Literaturstelle "Machinery and production engineering", Januar 1977, ist ein Verfahren bekannt, bei welcher mittels einer im Nuttiefsten halbkreis förmig gebogenen Stauchrolle einer Verdickung des Randbereiches einer Ronde angestrebt wird. Hierbei wird die im wesentlichen halbkreisförmig im Nut tiefsten geschaltete Stauchnut in ihrem Randbereich durch parallel zu den Außenseiten der Ronde verlau fende Wandabschnitte begrenzt. Ein Stauchen des äußeren Randbereiches der Ronde ist in der Praxis mit einer solchen Stauchrolle nicht möglich, da, wenn der Radius der Stauchnut in eine ebene Fläche übergeht, Reibungskräfte entstehen, die nicht mehr beherrschbar sind und eine Materialverformung erfolgt, die nicht fließend und kontinuierlich ist.From the reference "Machinery and production engineering ", January 1977, a method is known in which by means of a semicircle in the groove deepest Shaped roll of a thickening of the Edge area of a round blank is sought. Here becomes the substantially semicircular in the groove deepest switched compression groove in its edge area through parallel to the outer sides of the round blank limited wall sections. An upsetting of the outer edge area of the round blank is in practice not possible with such a compression roller because if the radius of the compression groove is in a flat surface passes, frictional forces arise that no longer are manageable and material deformation takes place that is not fluent and continuous.
Der Erfindung liegt die Aufgabe zugrunde, das aus der gattungsgemäßen DE-PS 35 39 835 bekannte Werkzeuge so zu verbessern, daß auch bei Einsatz eines sogenannten Stauchverfahrens eine zylin drische Auflagefläche geschaffen wird, in der das Anbringen einer Vertiefung im mittleren Bereich, also fluchtend mit der Ebene der Ronde möglich ist. The invention is based on the object the generic DE-PS 35 39 835 known To improve tools so that even when in use a so-called upsetting process a cylin drische contact surface is created in which the Making a depression in the middle area, in alignment with the plane of the round blank is possible.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Patentanspruches gelöst.This object underlying the invention will solved by the teaching of the claim.
Mit anderen Worten ausgedrückt wird vorgeschlagen, in der Stauchrolle an ihrer Arbeitsseite, d. h. an ihrem Umfang, eine Stauchnut vorzusehen, die also um gekehrt arbeitet und wirkt, wie die in der gattungs bildenden Literaturstelle beschriebene Schneidspitze und die die Umfangsseite der eigentlichen Ronde wul stig verformt. Diese Wulst wird dann anschließend durch weitere Stauchrollen so bearbeitet, daß die zylindrische Auflagefläche geschaffen wird, in der die letzte Stauchrolle die Nuten der Poly-V-Scheibe einpreßt. Hierbei ist es nunmehr möglich, daß auch im mittleren Bereich dieser Nuten, d. h. also fluchtend mit der Ebene der Ronde, eine Erhebung vorgesehen ist. Dieses ist dann nötig, wenn bei spielsweise drei Erhebungen über die Breite der Auf lagefläche vorgesehen sein sollen oder fünf, d. h. also eine ungerade Anzahl, und diese Anzahl der Er hebungen richtet sich nach dem Einsatzzweck der Poly-V-Scheibe.In other words, it is suggested in the compression roll on its working side, d. H. at their scope to provide a compression groove, which is around swept works and acts like that in the genre cutting tip described forming reference and the circumferential side of the round blank itself constantly deformed. This bead then becomes processed by further upsetting rollers so that the cylindrical contact surface is created in the the last compression roller is the grooves of the poly-V disc presses in. It is now possible that in the middle area of these grooves, i. H. so aligned with the plane of the round blank, an elevation is provided. This is necessary if at for example three surveys on the width of the up should be provided or five, d. H. so an odd number, and this number of Er lifting depends on the purpose of the Poly-V lens.
Ein Ausführungsbeispiel wird nachstehend anhand der Zeichnung erläutert. Die Zeichnung zeigt in Fig. 1 bis 4 verschiedene Stadien des Arbeitsverfahrens.An embodiment is explained below with reference to the drawing. The drawing shows in Fig. 1 to 4 different stages of the working process.
In der Zeichnung ist eine Stauchrolle 1 gezeigt, an deren Umfang eine halbkreisförmig ausgebil dete Stauchnut 2 vorgesehen ist.In the drawing, a compression roller 1 is shown, on the circumference of which a semicircular ausgebil Dete compression groove 2 is provided.
An einer Ronde 3 wird an ihrem Umfang eine wulstförmige Stauchung 4 durch das Zusammen wirken mit der Stauchnut 2 erzielt. On a circular blank 3 , a bead-like compression 4 is achieved on its circumference by acting together with the compression groove 2 .
In den weiteren Darstellungen, d. h. den Fig. 2 bis 4 der Zeichnung, ist nun die weitere Verformung der Ronde 3 dargestellt, und in Fig. 4 ist erkennbar, daß durch die Poly-V-Stauchrolle 1 c nunmehr die Einkerbung in die zylindrische Auflagefläche 5 eingepreßt werden, wobei, wie dies die Zeichnung deutlich zeigt, fluchtend mit der Ebene der Ronde 3 nunmehr auch im mittleren Teil der zylindrischen Auflagefläche 5 eine Erhebung geschaffen werden kann.In the further representations, ie FIGS. 2 to 4 of the drawing, the further deformation of the circular blank 3 is now shown, and in FIG. 4 it can be seen that the notch in the cylindrical contact surface is now due to the poly-V compression roller 1 c 5 can be pressed in, whereby, as the drawing clearly shows, in alignment with the plane of the round blank 3, an elevation can now also be created in the central part of the cylindrical bearing surface 5 .
