Description

Es sind Mehrfachdrahtzüge mit Ziehtrommeln bekannt, welche ohne Gleiten des Drahtes und mit Vorratsbildung arbeiten. jede dieser Ziehtrommeln besteht aus einem Paar auf der gleichen Welle gelagerter und sich in entgegengesetztem Sinne drehender Trommeln, deren eine angetriebene Trommel die Ziehtrommel und deren andere über der Ziehtrommel frei drehbar auf der Welle angeordnete die Abzugtrommel ist. Vo# dieser zieht die nächste Ziehtrommel den Draht ab-, wobei zwischen den Trommeln eine frei drehbare, mit dem Trommelflansch der Ziehtronnriel in Reibungsverbindung stehende Mittelscheibe angeordnet ist, deren über den Trommelumfang hinausragende Drahtführungsrolle den Drahtausgleich zwischen der Ziehtrommel und der Abzugstrommel bewirkt und deren Reibung an dem Trommelflansch- der Ziehtrommel mit Hilfe eine ' r hierfü7r'vorges-ehenen Einrichtung einstellbar ist.Multiple wire pulls with pulling drums are known which work without the wire sliding and with storage. Each of these pulling drums consists of a pair of drums mounted on the same shaft and rotating in opposite directions, one driven drum of which is the pulling drum and the other is the pulling drum, which is arranged above the pulling drum so that it can rotate freely on the shaft. From this the next pulling drum pulls the wire off, with a freely rotatable center disk in frictional connection with the drum flange of the pulling drum being arranged between the drums ehenen-hierfü7r'vorges to the Trommelflansch- the capstan by means of an 'r means is adjustable.

Diese bekannte Ausführung erzeugt eine, gleitende Reibung zwischen Mittelscheibe und Ziehtrommel, die von dem ablaufenden Draht überwunden werden muß. Da die Größe dieser gleitenden Reibung in weiten Grenzen schwankt, tritt beim-. Ziehen dünnster Drähte ein Abreißen des Drahtes ein.This known design creates a sliding friction between Center disc and pulling drum that the wire has to overcome. Since the size of this sliding friction fluctuates within wide limits, it occurs. Pulling in the thinnest wires causes the wire to tear.

Zweck der Erfindung ist es, diese gleitlos, mit Drahtansammlung arbeitenden Mehrfachziehmaschinen so zu verbessern, daß es möglich ist, auch allerfeinste Drähte auf ihnen zu ziehen.The purpose of the invention is to make this work smoothly with wire accumulation To improve multiple drawing machines so that it is possible to process even the finest wires to draw on them.

Der Erfindungsgegenstand ist in der Fig. i bis 4 dargestellt. Es zeigt Fig. i einen Axialschnitt durch eine Ziehtrommel mit Differentialabnehmer und der erfindungsgemäßen Lagerung der Mittelscheibe auf Rollen, Fig.:2 eine Draufsicht auf diese Trommel, Fig. 3, 4 die Anordnung der Trommel innerhalb einer Drahtziehmaschine in Ansicht und Draufsicht. Der Erfindungsgegenstand besteht aus der unteren Ziehtrommel:2, welche mit der Antriebswelle i fest verbunden ist, und aus der auf der Antriebswelle i sich unter der Wirkung des ablaufenden Drahtes frei in entgegengesetztem Sinne wie die Ziehtrommel drehenden Abzugstrommel 4. Zwischen diesen beiden Trommeln:2 und 4 läuft frei drehbar auf der Antriebswelle i die Mittelscheibe 3, in welcher Rollen 5 angeordnet sind, die sich auf den Flanschen der Trommeln:2 und 4 abwälzen und deren Achsen 6 senkrecht zur Achse i stehen. Das sichere Abwälzen der Rollen 5 auf den Flanschen der Trommeln:2 und 4 ist bei senkrecht stehender Achse i durch das Gewicht der Abzugstrommel 4 gewährleistet. Bei waagerechter Lage der Achse i kann durch seitlichen'Federdruck das sichere Ab- wälzen erreicht werden. Die an der Mittelscheibe 3 angebrachte Rolle 7 führt den Draht von der Ziehtrommel:2 auf die sich unter dem Einfluß des ablaufenden Drahtes in entgegengesetztem Sinne drehende AbzugstrOmmel 4. Die Umlaufgeschwindigkeit der Abzugstrommel 4 ergibt sich also aus der Umlaufgeschwindigkeit (Ziehgeschwindigkeit) der Ziehtrommel:2 und der Querschnittsveränderung der nächstfolgenden Ziehstufe.The subject of the invention is shown in FIGS. 1 shows an axial section through a drawing drum with a differential pick-up and the inventive mounting of the center disk on rollers, FIG. 2 shows a top view of this drum, FIGS. 3, 4 show the arrangement of the drum within a wire drawing machine in top and bottom view. The subject matter of the invention consists of the lower pulling drum: 2, which is firmly connected to the drive shaft i, and the pull-off drum that rotates freely on the drive shaft i under the action of the unwinding wire in the opposite direction to the pulling drum 4. Between these two drums: 2 and 4 runs freely rotatably on the drive shaft i, the central disk 3, in which rollers 5 are arranged, which roll on the flanges of the drums: 2 and 4 and whose axes 6 are perpendicular to the axis i. The safe rolling of the rollers 5 on the flanges of the drums: 2 and 4 is ensured by the weight of the haul-off drum 4 when the axis i is vertical. With the horizontal position of axis i, safe rolling can be achieved by lateral spring pressure. The roller 7 attached to the central disk 3 guides the wire from the drawing drum: 2 to the take-off drum 4, which rotates in the opposite direction under the influence of the running wire and the change in cross-section of the next drawing stage.

Der Arbeitsvorgang der Ziehtrommel ist wie folgt: Der Draht wird zunächst durch den Ziehstein 8 der ersten Ziehstufe über die Ziehtrommel 2 und die an der Mittelscheibe3 befestigteFührungsrolle 7 zur Abzugs#rOnimel 4 geführt. Draht und AbzugstrOmmel 4 werden nun von Hand festgehalten, so daß sich der Draht zunächst unter dem Einfluß der an der Mittelscheibe 3 befestigten Rolle 7 auf beiden Trommeln aufwickelt. Nach einigen Umdrehungen, d. h. wenn die Reibung der Drahtwindungen auf der Zichtrommel :2 größer ist als der eigentliche Ziehwiderstand, kann die Abzugstrommel 4 freigegeben und der Draht zur nächstfolgenden Ziehstufe geführt werden.The working process of the drawing drum is as follows: The wire is first guided through the drawing die 8 of the first drawing stage via the drawing drum 2 and the guide roller 7 attached to the center disk 3 to the take-off # rOnimel 4. The wire and take-off drum 4 are now held by hand so that the wire initially winds up on both drums under the influence of the roller 7 attached to the central disk 3. After a few turns, i.e. H. if the friction of the wire windings on the drawing drum: 2 is greater than the actual drawing resistance, the drawing-off drum 4 can be released and the wire can be guided to the next drawing stage.

Da der Draht auf dem Weg zur nächsten Ziehstufe die Abzugstrommel in Umlauf hält, jedoch hierbei keine gleitende Reibung zu überwinden hat, ist es möglich, feinste Drähte gleitlos mit Drahtansammlung.zu ziehen.As the wire passes the take-off drum on the way to the next drawing stage keeps in circulation, but has no sliding friction to overcome, it is possible to draw the finest wires without sliding with wire accumulation.
