Description

Die Erfindung bezieht sich auf eine Vorrichtung ge­ mäß dem Oberbegriff des Patentanspruches.The invention relates to a device ge according to the preamble of the claim.

Aus der EP-O 126 489 A1 ist ein Verfahren zur Herstellung von Poly-V-Scheiben bekannt, bei welchem eine Ronde mittels einer Spaltrolle so gespalten wird, daß zwei Flansche entstehen, die jeweils gleiches Volumen aufweisen und dabei zusammen der Stärke des Mittelteiles der Ronde entsprechen. Wie dies in Fig. 29 und 30 dieser Literaturstelle zeigen, werden dann durch entsprechende Formrollen in diese Flansche die Nuten eingedrückt.From EP-O 126 489 A1 a process for the production of poly-V-disks is known, in which a round blank is split by means of a split roller in such a way that two flanges are created, each having the same volume and together the thickness of the central part of the Round blank. As shown in FIGS. 29 and 30 of this literature reference, the grooves are then pressed into these flanges by corresponding shaping rollers.

In der DE 38 06 024 C1 wird die gattungsbildende Vorrichtung beschrieben. Die erste Stauchrolle weist an ihrer Arbeitsseite, d. h. ihrem Umfang, eine Stauchnut auf, die die Umfangsseite der zu bearbeitenden Ronde wulstig verformt. Dieser Wulst wird dann anschließend durch weitere Stauchrollen so bearbeitet, daß die zylindrische Auflagefläche ge­ schaffen wird, in der die letzte Stauchrolle die Nuten der Poly-V-Scheibe einpreßt.DE 38 06 024 C1 describes the generic Device described. The first compression roll points to their working side, d. H. their scope, a compression groove on the circumferential side of the machining round blank deformed. This bead is then done by further upsetting rollers edited that the cylindrical bearing surface ge will create in which the last upset roll Grooves in the poly-V washer.

Der Einrichtung liegt die Aufgabe zugrunde, die erste Stauchrolle so auszubil­ den, daß ein besserer Materialfluß im Randbereich der zu bearbeitenden Ronde erzielt wird, so daß ein schnelleres Bearbeitungsverfahren möglich ist. The facility is the Based on the task of training the first compression roll in this way that a better material flow in the edge area the blank to be machined is achieved so that a faster machining process is possible.  

Diese der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß die Stauchrolle auf ihrem Umfang, zwei umlaufende im Querschnitt teilkreisförmige Stauch­ nuten aufweist, deren Sattellinie in der Mittelebene der Stauchrolle liegt und zu Beginn des Stauchvorganges die Mittelebene der Ronde beaufschlagt.This object underlying the invention will solved by that the squeeze roller on its circumference, two circumferential, partially circular cross-section has grooves, the saddle line in the Middle level of the compression roll lies and at the beginning of the upsetting process the central plane of the round blank acted upon.

Durch diese Anordnung wird bewirkt, daß das Material in der Ronde besser fließt und daher weniger ver­ härtet. Aus diesem Grund kann mit der nachfolgenden Stauchrolle wesentlich schneller gefahren, d. h. ge­ arbeitet werden.This arrangement causes the material flows better in the round blank and therefore less ver  hardens. For this reason, the following can Squeeze roller moved much faster, d. H. ge be working.

Außerdem hat diese erfindungsgemäße Anordnung wei­ terhin den Vorteil, daß aufgrund der geringeren Ver­ härtung des Materials die nachfolgenden Bearbei­ tungsrollen erheblich geschont werden.In addition, this arrangement according to the invention has white terhin the advantage that due to the lower Ver hardening of the material the following processing tion rollers are considerably protected.

Ein Ausführungsbeispiel der Erfindung wird nach­ folgend anhand der Zeichnung erläutert. Die Zeich­ nung zeigt dabei inAn embodiment of the invention will follow explained below with reference to the drawing. The drawing nation shows in

Fig. 1 bis 4 verschiedene Stadien des der Erfindung zugrundeliegenden Arbeitsverfah­ rens. Fig. 1 to 4 different stages of the working method underlying the invention.

In der Zeichnung ist eine Stauchrolle 1 gezeigt, an deren Umfang zwei umlaufende, im Querschnitt teilkreisförmig ausgebildete Stauchnuten 6 und 6a vorgesehen sind.In the drawing, a compression roller 1 is shown, on the circumference of which two circumferential compression grooves 6 and 6 a, which are partially circular in cross section, are provided.

An einer Ronde 3 werden an ihrem Umfang bei Einsatz dieser Stauchrolle 1 zwei gewölbte, nach außen ge­ richtete flügelartige Teile 4 und 4a erzielt.This compression roller 1 at its periphery two arched in use on a round plate 3, achieved outwardly ge directed wing-like parts 4 and 4a.

In den weiteren Darstellungen, d. h. in den Fig. 2 bis 4 der Zeichnung, ist nun die weitere Verformung der Ronde 3 dargestellt, und in Fig. 4 ist erkenn­ bar, daß durch eine Poly-V-Stauchrolle 1c nunmehr Einkerbungen in die zylindrische Auflagefläche 5 ein­ gepreßt werden, wobei - wie dies die Zeichnung deut­ lich 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 in FIGS. 2 to 4 of the drawing, the further deformation of the round blank 3 is now shown, and in FIG. 4 it can be seen that a poly-V compression roller 1 c now has notches in the cylindrical Contact surface 5 can be pressed, whereby - as the drawing clearly shows - in alignment with the plane of the circular blank 3, an elevation can now also be created in the central part of the cylindrical contact surface 5 .
