Description

Beim Drahtziehen erfolgt die Querschnittsabnahme meistens in mehreren Zügen. Da der Drahtwerkstoff durch das Ziehen erhärtet, ist es bisher üblich gewesen, den Draht zwischen den Zügen ein oder mehrere Male in gesondertem Verfahren weich zu glühen. Dieser besondere Arbeitsvorgang hat eine zeitraubende Unterbrechung des Ziehvorganges zur Folge.In wire drawing, the cross-section is usually reduced in several steps Trains. Since the wire material hardens through drawing, it has been common up to now to Soften the wire one or more times in a separate process between the pulls to glow. This particular operation has a time consuming interruption of the Drawing process result.

Es ist auch bereits bekannt, bei einer Mehrfachdrahtziehmaschine zwischen aufeinanderfolgenden Ziehstufen für den zu ziehenden Draht Glüh- und Kühlrohre anzuordnen. Derartige Einrichtungen beanspruchen aber an den Drahtziehmaschinen viel Platz. It is also already known to arrange annealing and cooling tubes between successive drawing stages for the wire to be drawn in a multiple wire drawing machine. Such devices, however, take up a lot of space on the wire drawing machines.

Erfindungsgemäß wird daher eine Mehrfachdrahtziehmaschine vorgeschlagen, bei der die Glüh- vorrichtung lediglich aus einem mit seiner Austrittsseite in die Ziehflüssigkeit eintauchenden Rohr besteht. Bei dieserAusführungsform wird einKühlrohr nicht mehr benötigt. Vielmehr dient hierbei die ohnehin in der Mehrfachdrahtziehmaschine schon vorhandene Ziehflüssigkeit gleichzeitig zur Kühlung des Drahtes sowie zum Abschluß des Glühraumes. Darüber hinaus gewährleistet der aus der Glühvorrichtung in die Ziehflüssigkeit einlaufende Draht eine gleichmäßigeTemperierung der Ziehflüssigkeit, wodurch der Ziehprozeß günstig beeinflußt wird.According to the invention, therefore, a multiple wire drawing machine is proposed in which the annealing device consists only of a tube which is immersed in the drawing liquid with its outlet side. In this embodiment, a cooling pipe is no longer required. Rather, the drawing liquid already present in the multiple wire drawing machine serves at the same time to cool the wire and to close off the annealing space. In addition, the wire running from the annealing device into the drawing liquid ensures a uniform temperature control of the drawing liquid, which has a beneficial effect on the drawing process.

Es empfiehlt sich, den zu ziehenden Draht in der Glühvorrichtung elektrisch, beispielsweise durch Widerstands- oder Hochfrequenzerhitzung, zu heizen.It is recommended that the wire to be drawn in the annealing device is electrically, for example by resistance or high frequency heating to heat.

Insbesondere kann der zu ziehende Draht in der Glühvorrichtung vorteilhafterweise durch Stromzuführung über Bürsten und Rollen direkt erhitzt werden. In diesem Fall läßt sich das Glührohr besonders kurz ausführen.In particular, the wire to be drawn in the annealing device can advantageously directly heated by power supply via brushes and rollers. In this case the glow tube can be made particularly short.

Die Zeichnung zeigt in schematischer Darstellung ein Ausführungsbeispiel der Mehrfachdrahtziehmaschine nach der Erfindung. Der Draht i läuft unter dem Spiegel der Ziehflüssigkeit 2 durch eine Anzahl Ziehwerkzeuge (Ziehsteine) 3 und über eine Anzahl Scheiben4. Zwischen einigen der Ziehwerkzeuge 3 sind die aus den winklig gebogenen Rohren 5 bestehenden Glühvorrichtungen angeordnet. Die Glührohre 5 sind jeweils auf ihrer Eintrittsseite durch die Scheiben 6 abgeschlossen und tauchen mit ihrerAustrittsseite7 unter den Spiegel der Ziehflüssigkeit 2.The drawing shows a schematic representation of an embodiment of the multiple wire drawing machine according to the invention. The wire i runs under the level of the drawing liquid 2 through a number of drawing tools (drawing dies) 3 and over a number of disks 4. Between some of the drawing tools 3 , the annealing devices consisting of the tubes 5 bent at an angle are arranged. The glow tubes 5 are each closed on their inlet side by the panes 6 and their outlet side 7 plunges under the level of the drawing liquid 2.

Der Draht i wird in den Rohren 5 mittels der Rollen 8 geführt. Das Glühen des Drahtes i erfolgt in dem dargestellten Beispiel durch elektrische Widerstandsheizung, zu welchem Zweck dem Draht über die Bürsten 9 und die Rollen 8 Strom zugeführt wird.The wire i is guided in the tubes 5 by means of the rollers 8. The annealing of the wire i takes place in the example shown by electrical resistance heating, for which purpose the wire is supplied with electricity via the brushes 9 and the rollers 8.
