Description

Die Erfindung betrifft Laufringe für Kontaktscheiben einer Drahtdurchlaufwiderstandsglühe einer Drahtziehmaschine.The invention relates to races for contact disks one Continuous wire resistance annealing of a wire drawing machine.

Solche Laufringe dienen dazu, elektrischen Strom zum Er­ hitzen des zu behandelnden Drahtes auf den Draht zu über­ tragen, und sind beispielsweise aus DE-AS-10 97 934 be­ kannt. Als mögliche Materialien für jene bekannten Laufrin­ ge werden dort Stahl oder Bronze angegeben. Laufringe aus derartigen Materialien haben sich wegen zu hohen Verschlei­ ßes als unbefriedigend erwiesen.Such races are used to generate electrical current heat the wire to be treated to over the wire wear, and are for example from DE-AS-10 97 934 be knows. As possible materials for those known Laufrin Steel or bronze are specified there. Race rings Such materials have become worn due to excessive wear proved unsatisfactory.

Ein spezielles Problem bei gattungsgemäßen Laufringen be­ steht darin, daß sowohl die Führungsfläche der Laufringe als auch der zu behandelnde Draht leicht durch Funken­ erosionen beschädigt werden.A special problem with generic races is that both the guide surface of the races as well as the wire to be treated easily by sparks erosions are damaged.

Solche Laufringe unterliegen damit grundsätzlich anderen Anforderungen als beispielsweise nach DE-C-27 60 252 bei der Drahtherstellung verwendete Ziehringe. Jene Ziehringe sind nämlich ausschließlich einem hohen mechanisch beding­ ten Verschleiß ausgesetzt und sollen daher aus Hartmetall bestehen. Konkret angegeben sind dort unter anderem die Hartmetalle Wolframcarbid und Chromcarbid, wobei diese in einer Matrix aus Kobalt enthalten sein können. Soweit die Oberflächen jener Hartmetalle nach den dortigen Angaben mit beispielsweise Cu-Ionen geimpft werden können, handelt es sich ausschließlich um eine Oberflächenbehandlung mit ge­ ringer Tiefenwirkung.Such races are therefore fundamentally different Requirements as for example according to DE-C-27 60 252 drawing rings used in wire production. Those pull rings are only mechanically high exposed to wear and should therefore be made of hard metal consist. Specifically, there are, among others, the Hard metals tungsten carbide and chromium carbide, these in may contain a matrix of cobalt. So far the Surfaces of those hard metals according to the information given there for example, Cu ions can be vaccinated, it is  deal exclusively with a surface treatment with ge ringer depth effect.

Das Problem, mit dem sich die Erfindung beschäftigt, be­ steht allein bei den gattungsgemäßen Laufringen und bezieht sich darauf, das hauptsächlich funkenerosionsbedingte Ver­ schleißverhalten solcher Laufringe zu verbessern und damit gleichzeitig die Gefahr von Drahtbeschädigungen durch von zerklüfteten Laufringoberflächen ausgehenden Funkenbildun­ gen zu verringern.The problem with which the invention is concerned be stands alone with the generic races and relates relies on the mainly spark erosion related Ver to improve the wear behavior of such races and thus at the same time the risk of wire damage from jagged raceway surfaces gene to reduce.

Gelöst wird diese Aufgabe durch einen Werkstoff für die Laufringe nach den kennzeichnenden Merkmalen des Patentan­ spruchs 1.This task is solved by a material for the Races according to the characterizing features of the patent saying 1.

Eine zweckmäßige Ausgestaltung des erfindungsgemäßen für die Laufringe vorgeschlagenen Werkstoffes ist Gegenstand des Anspruchs 2. An expedient embodiment of the invention for The raceway proposed material is the subject of claim 2.  

Die Zeichnung zeigt drei Ausführungsbeispiele mittels dreier Axialschnitte. Gemäß derThe drawing shows three exemplary embodiments by means of three axial cuts. According to the

Fig. 1 dient ein einziger Laufflächenring als Kontaktscheibe, während nach den Fig. 1 serves a single tread ring as a contact washer, while after

Fig. 2 und 3 fünf bzw. drei Kontaktscheiben verwendet sind. Fig. 2 and 3, five and three contact plates are used.

In allen drei Fällen sind die Laufflächenringe 3 außen zentriert. Die Halterungen sind die Teile 1, 2 und 4.In all three cases, the tread rings 3 are centered on the outside. The brackets are parts 1, 2 and 4 .
