Abstract
Description
Die Erfindung bezieht sich auf eine an ihrem Umfang eine Stauchnut aufweisende Stauchrolle zur Her stellung von eine zylindrische Auflagefläche auf weisenden Werkstücken, wie Poly-V-Scheiben, Felgen od. dgl.The invention relates to one in its scope a compression roller having a compression groove for the manufacture position of a cylindrical support surface pointing workpieces, such as poly-V discs, rims or the like
In der DE-PS 39 17 925 wird ein Verfahren zur Her stellung einer asymmetrischen Riemenscheibe aus einer Metallronde beschrieben, bei welcher die Stauchrolle an ihrer Arbeitsseite, d. h. ihrem Um fang, eine Stauchnut aufweist, die die Umfangsseite der zu bearbeitenden Ronde wulstig verformt. Dieser Wulst kann symmetrisch zur Rondenfläche stehen und wird dann in einem zweiten Arbeitsverfahren durch Umlegen asymmetrisch angeordnet oder der Wulst kann durch entsprechende Gestaltung der Stauchrolle sofort etwas asymmetrisch gestaltet sein. Dieser Wulst wird dann anschließend durch weitere Stauch rollen so bearbeitet, daß die zylindrische Auf lagefläche geschaffen wird, in der die letzte Stauchrolle die Nuten der Poly-V-Scheibe einpreßt.In DE-PS 39 17 925 a method for Her position of an asymmetrical pulley described a metal blank, in which the Squeeze roll on their working side, d. H. their order catch, has a compression groove that the peripheral side the blank to be machined is beaded. This Bead can be symmetrical to the disk surface and is then carried out in a second working process Fold asymmetrically or the bead can by designing the compression roller accordingly immediately be designed asymmetrically. This The bulge is then further compressed roll machined so that the cylindrical on is created, in which the last Squeeze roller presses in the grooves of the poly-V disc.
Diese Verfahrensweise ist deshalb nachteilig, da zur Bildung des Wulstes ein Stauchverfahren einge setzt wird, das eine Materialverformung bedingt, bei welchem das Material nicht fließt und vor allen Dingen nicht kontinuierlich fließt, sondern ausschließlich gestaucht und gedrückt wird. Durch das bekannte Stauchen wird eine Verhärtung des Materials bedingt, wobei sich diese Verhärtung des Materials nachteilig auf die nachfolgenden Arbeitsverfahren auswirkt, und zwar sowohl hinsichtlich der Material qualität als auch der Schnelligkeit des möglichen Arbeitens.This procedure is disadvantageous because a compression process is used to form the bead is set that causes material deformation, where the material does not flow and before everything does not flow continuously, but is only compressed and pressed. By the Known upsetting will harden the material conditional, whereby this hardening of the material disadvantageous to the subsequent working procedures affects, both in terms of material quality as well as the speed of the possible Working.
Der Erfindung liegt die Aufgabe zugrunde, eine Stauchrolle zu schaffen, mit der das Arbeitsver fahren schnell durchgeführt werden kann und uner wünschte Materialveränderungen und Materialverhär tungen nicht auftreten.The invention has for its object a To create upsetting roll with which the Arbeitsver driving can be done quickly and un desired material changes and material hardening not occur.
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 in einem ersten Arbeitsschritt die Ronde asymmetrisch verformt, wo bei aber die Verformung durch ein "Fließen" des Materials bedingt wird, d. h. der Stauchdruck drückt den äußeren Umfangsbereich der Ronde nicht zu einem Wulst zusammen, sondern verformt den Randbe reich zu einer relativ breiten, der nachfolgenden Bearbeitung dienlichen Auflagefläche.In other words, it is expressed in a first Working step the disc is asymmetrically deformed where but the deformation caused by a "flow" of the Material is conditioned, d. H. the upsetting pressure presses the outer circumferential area of the round blank a bulge together, but deforms the edge rich to a relatively broad, the following Machining of the support surface.
Ein Ausführungsbeispiel der Erfindung wird nachfol gend anhand der Zeichnung erläutert. Die Zeichnung zeigt dabei in denAn embodiment of the invention will follow explained using the drawing. The drawing shows in the
Fig. 1 bis 4 verschiedene Stadien des Arbeits verfahrens. Fig. 1 to 4 different stages of the working process.
In der Zeichnung ist eine Stauchrolle 1 gezeigt, an deren Umfang eine Stauchnut 2 vorgesehen ist.In the drawing, a compression roll 1 is shown, on the circumference of which a compression groove 2 is provided.
An einer Ronde 3 wird an ihrem Umfang eine Verdickung 4 durch das Zusammenwirken mit der Stauchnut 2 erzielt.On a circular blank 3 , a thickening 4 is achieved on its circumference through the interaction with the compression groove 2 .
Die Stauchnut 2 weist einseitig einen Begrenzungswulst 5 auf, an den sich zurückversetzt eine zum Stauchnutinneren hin geneigte, d. h. abfallende Stauchfläche 6 anschließt. Der Begrenzungswulst 5 dient also als Widerlager beim Durchführen des Abeitsverfahrens für das nach dieser Seite hin ausfließenden Materials des Rondenrandes.The compression groove 2 has a limiting bead 5 on one side, to which a compression surface 6 inclined toward the interior of the compression groove, that is to say falling, is connected. The delimitation bead 5 thus serves as an abutment when carrying out the machining process for the material of the blank edge flowing out towards this side.
An das innere Ende der Stauchfläche 6 schließt eine in radialer Richtung ansteigende Stauchfläche 7 an, deren äußeres, in radialer Richtung gerichtetes Ende aber gegenüber dem äußeren in radialer Richtung ausgerichteten Ende des Begrenzungswulsts 5 zurückversetzt ist. Hier könnte also ein freies Ausfließen des Rondenmaterials der Verdickung 4 erfolgen.At the inner end of the compression surface 6 there is a compression surface 7 which rises in the radial direction, but whose outer end directed in the radial direction is set back relative to the outer end of the limiting bead 5 oriented in the radial direction. So there could be a free flow of the round material of the thickening 4 .
In den weiteren Darstellungen, d. h. in den Fig. 2 bis 4 der Zeichnung ist die weitere Verformung der Ronde 3 dargestellt, ohne daß es hierzu näherer Erläuterungen bedarf, da diese Arbeitsweise im Prinzip zum Stand der Technik gehört.In the other representations, that is to say in FIGS. 2 to 4 of the drawing, the further deformation of the round blank 3 is shown without any further explanation being necessary, since this method of operation is in principle part of the prior art.
