Abstract

An arrangement for laying a wire in circular windings by bending the wire to circular form during simultaneous twisting includes a wire conveying device and a consecutively arranged laying head including a rotating laying pipe, whose central axis is oriented tangentially to the wire axis on the wire entry end and which gradually passes from the entry end into a circular arc directed approximately perpendicular to the axis of rotation, its center lying on the axis of rotation. A twisting device is provided between the wire conveying means and the laying head. In order to be able to lay wires of larger diameters in closely adjacent windings, the twisting device is formed by a bent pipe twisting the wire under positive locking and frictional engagement.

Description

Die Erfindung betrifft eine Einrichtung zum Legen eines Drahtes in kreisförmige Windungen durch Biegen des Drahtes in Kreisform unter gleichzeitigem Verdrillen, mit einer Drahtfördereinrichtung und einem nachgeordneten Windungsleger, der ein rotierendes Legerohr aufweist, dessen Mittelachse am Drahteintrittsende tangential zur Drahtachse ausgerichtet ist und das vom Eintrittsende allmählich in einen etwa senkrecht zur Rotationsachse gerichteten Kreisbogen übergeht, dessen Mittelpunkt auf der Rotationsachse liegt, wobei zwischen der Drahtfördereinrichtung und dem Windungsleger eine Verdrilleinrichtung vorgesehen ist.The invention relates to a device for laying a wire in circular turns by bending the wire in a circular shape with simultaneous twisting, with a wire conveyor and a downstream winding layer, which has a rotating laying tube, the central axis of which is aligned tangentially to the wire axis and that gradually from the entry end merges into a circular arc oriented approximately perpendicular to the axis of rotation, the center point of which lies on the axis of rotation, a twisting device being provided between the wire conveying device and the winding layer.

Zum Verlegen von warmgewalztem Draht in Form von flachliegenden, annähernd kreisförmigen Windungen auf einem Rollgang ist es bekannt, einen Windungsleger zu verwenden (US-A-4,765,556). Ein Windungsleger weist ein räumlich gekrümmtes Legerohr auf, durch das der Draht geführt wird. Das Legerohr bildet somit eine Bahn, entlang der der Draht zwangsgeführt ist.For laying hot-rolled wire in the form of flat, approximately circular windings on a roller table, it is known to use a winding layer (US-A-4,765,556). A winding layer has a spatially curved laying tube through which the wire is passed. The laying pipe thus forms a path along which the wire is positively guided.

Das Legerohr rotiert um eine Achse, die eine Tangente an die Mittellinie des Legerohranfanges darstellt. Der vom Drahtblock bzw. der Drahtstraße oder mittels eines eigenen Antriebsaggregates geförderte Draht läuft geradlinig und in Richtung dieser Tangente in den Legerohranfang ein. Das zweite Ende des Legerohres hat annähernd die Form eines Kreisbogens. Dieser Kreisbogen befindet sich in einer zur Rotationsachse des Legerohres näherungsweise senkrechten Ebene. Der Kreisbogenmittelpunkt befindet sich auf der Rotationsachse. Aus diesem Legerohrende läuft der zu Windungen mit Kreisform gebogene Draht.The laying pipe rotates around an axis that represents a tangent to the center line of the beginning of the laying pipe. The wire conveyed by the wire block or the wire mill or by means of its own drive unit runs straight and in the direction of this tangent into the beginning of the laying pipe. The second end of the laying tube has approximately the shape of an arc. This circular arc is located in a plane approximately perpendicular to the axis of rotation of the laying tube. The center of the arc is on the axis of rotation. The wire bent into coils with a circular shape runs from this end of the pipe.

Die Winkelgeschwindigkeit, mit der das Legerohr rotiert, ist so gewählt, daß die Größen der Umfangsgeschwindigkeit des einen Kreisbogen bildenden Endes des Legerohres und der Geschwindigkeit des eintretenden Drahtes betragsmäßig gleich groß sind. Die Drehrichtung des Legerohres ist so gewählt, daß die Absolutgeschwindigkeit des auslaufenden Drahtes Null wird. Somit bilden sich am Windungslegerende stehende Drahtschleifen, welche infolge der Schwerkrafteinwirkung umkippen und üblicherweise auf einem Luftkühlrollgang zu einer Bundbildekammer transportiert werden.The angular velocity at which the laying tube rotates is chosen so that the magnitudes of the circumferential speed of the end of the laying tube forming an arc and the speed of the incoming wire are equal. The direction of rotation of the laying tube is selected so that the absolute speed of the outgoing wire becomes zero. Consequently Form wire loops at the end of the winding layer, which tip over due to the action of gravity and are usually transported on an air cooling roller table to a bundle forming chamber.

Bei bestimmten Drahtqualitäten, Drahtdurchmessern und Drahttemperaturen führt die elastische Rückfederung des Drahtes dazu, daß der Draht nicht in eng aneinanderliegenden Windungen das Legerohr verläßt, sondern nach dem Austritt aus dem Windungsleger eine Schraubenlinie mit so großer Steigung bildet, daß die einzelnen Windungen nicht mehr umkippen, wodurch der Weitertransport bzw. die weitere Verarbeitung des Drahtes zu Bundformen in der Bundbildekammer nicht mehr möglich ist. Diese Schraubenlinie entsteht durch Torsionsauffederung des Drahtes infolge dessen elastoplastischen Verhaltens. Die Steigung der Schraubenlinie, die auch von der Form des Legerohres abhängig ist, kann bei großen Drahtdurchmessern größer sein als der Windungsdurchmesser des Drahtes.With certain wire qualities, wire diameters and wire temperatures, the elastic springback of the wire means that the wire does not leave the laying tube in tightly adjacent turns, but instead forms a helix with a pitch that is so large after it emerges from the winding layer that the individual turns no longer tip over. whereby the further transport or further processing of the wire to form bundles in the bundle forming chamber is no longer possible. This helix is created by torsion springing of the wire due to its elastoplastic behavior. The pitch of the helix, which also depends on the shape of the laying tube, can be larger than the winding diameter of the wire for large wire diameters.

Zur Vermeidung dieser Nachteile ist es aus der DD-PS 109.329 bekannt, die Verdrallung auf den Teil des Drahtes zwischen dem letzten Walzgerüst und dem Treiber zurückzuverschieben. Dies wird bei einer Einrichtung der eingangs beschriebenen Art dadurch erreicht, daß vor der Legevorrichtung ein Treiber angeordnet ist, dessen Treibscheibenachsen gegeneinander verschränkt sind. Dabei wird jede Treibscheibe mit ihrer Lagerung um einen Winkel bis zu 3° senkrecht zur Drahtrichtung verstellbar angeordnet.To avoid these disadvantages it is known from DD-PS 109.329 to move the twist back onto the part of the wire between the last roll stand and the driver. This is achieved in a device of the type described in the introduction in that a driver is arranged in front of the laying device, the drive pulley axes of which are interlaced with one another. Each traction sheave is arranged so that it can be adjusted by an angle of up to 3 ° perpendicular to the wire direction.

Die Erfindung stellt sich die Aufgabe, eine Einrichtung der eingangs beschriebenen Art sowie ein Verfahren zu schaffen, die es ermöglichen, Drähte, die infolge der elastischen Rückfederung, bedingt durch das Werkstoffverhalten und die Größe des Drahtdurchmessers, nicht mehr verlegt werden können (insbesondere im Durchmesserbereich von 10 bis 25 mm), in Windungen zu legen, wobei die aus dem Windungsleger austretende Drahtschraube nur eine geringe Steigung aufweist, so daß die Drahtwindungen eng benachbart sind. Insbesondere soll die Steigung der Drahtschraube nach Wunsch variiert werden können.The invention has for its object to provide a device of the type described above and a method that enable wires that can no longer be laid due to the elastic springback due to the material behavior and the size of the wire diameter (especially in the diameter range from 10 to 25 mm), in turns, the wire screw emerging from the winding layer having only a slight pitch, so that the wire turns are closely adjacent. In particular, the pitch of the wire screw should be able to be varied as desired.

Diese Aufgabe wird bei einer Einrichtung der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Verdrilleinrichtung von einem den Draht unter Form- und Reibschluß verdrillenden gebogenen Rohr gebildet ist.This object is achieved according to the invention in a device of the type described in the introduction in that the twisting device is formed by a bent tube which twists the wire under positive and frictional engagement.

Als Drahtfördereinrichtung kann hierbei der Drahtblock bzw. die Drahtstraße oder eine eigene zusätzliche Einrichtung zwischen dem Drahtblock und dem Windungsleger fungieren, wobei es sich insbesondere beim Legen von Drähten mit größeren Durchmessern als notwendig erweisen kann, zwischen der Verdrilleinrichtung und dem Windungsleger eine weitere Drahtfördereinrichtung vorzusehen.The wire block or the wire mill or a separate additional device between the wire block and the winding layer can function as a wire conveyor, whereby it may prove necessary, especially when laying wires with larger diameters, to provide a further wire conveyor between the twisting device and the winding layer.

Vorzugsweise fluchtet das Ein- und Austrittsende des Rohres mit der Rotationsachse des Windungslegers, wobei das Rohr um die Rotationsachse des Windungslegers in Rotation versetzbar ist. Die Rotationsachsen des Windungslegers und der Einrichtung für die Vorverdrillung können auch zueinander geneigt ausgerichtet sein. Die Verdrilleinrichtung und der Windungsleger müssen auch nicht unmittelbar hintereinander angeordnet sein.The inlet and outlet ends of the tube are preferably aligned with the axis of rotation of the winding layer, wherein the tube can be set in rotation about the axis of rotation of the winding layer. The axes of rotation of the winding layer and the device for the pre-twisting can also be oriented inclined to one another. The twisting device and the winding layer do not have to be arranged directly one behind the other.

Eine besonders einfach gestaltete Ausführungsform ist dadurch gekennzeichnet, daß das gebogene Rohr U-förmig ausgebildet ist.A particularly simple embodiment is characterized in that the bent tube is U-shaped.

Eine Einrichtung, die es gestattet, den Draht mit nur einem geringen Teil an zu leistender Biegearbeit zu verdrillen, ist dadurch gekennzeichnet, daß das gebogene Rohr als um 360° gebogene Schlinge ausgebildet ist.A device which allows the wire to be twisted with only a small part of the bending work to be performed is characterized in that the bent tube is designed as a loop bent through 360 °.

Zweckmäßig ist das gebogene Rohr mit einer Winkelgeschwindigkeit antreibbar, die größer oder gleich ist als bzw. wie die des Legerohres des Windungslegers.The bent tube can expediently be driven at an angular velocity which is greater than or equal to or as that of the laying tube of the winding layer.

Vorteilhaft ist die Winkelgeschwindigkeit des gebogenen Rohres variabel einstellbar, wodurch es möglich ist, die Steigung der aus dem Windungsleger austretenden Drahtschraube zu variieren, z.B. auf einen bestimmten Wert einzustellen oder auf sich während des Windungslegens ändernde Betriebsbedingungen anzupassen.The angular velocity of the bent tube can advantageously be variably adjusted, which makes it possible to vary the pitch of the wire screw emerging from the winding layer, for example to set it to a certain value or to adapt it to changing operating conditions during the winding.

Das Verhältnis der Winkelgeschwindigkeiten ist in erster Linie vom Werkstoffverhalten, dem Drahtdurchmesser und dem Durchmesser der gelegten Windungen abhängig.The ratio of the angular velocities depends primarily on the material behavior, the wire diameter and the diameter of the turns.

Vorteilhaft liegt das Verhältnis der Winkelgeschwindigkeit des gebogenen Rohres zur Winkelgeschwindigkeit des Legerohres des Windungslegers im Bereich zwischen 2,5 und 4.The ratio of the angular velocity of the bent tube to the angular velocity of the laying tube of the winding layer is advantageously in the range between 2.5 and 4.

Ein bevorzugtes Verfahren zum Legen eines Drahtes in kreisförmige Windungen unter Verwendung einer erfindungsgemäßen Einrichtung ist dadurch gekennzeichnet, daß das zusätzliche Verdrillen mit einer Winkelgeschwindigkeit erfolgt, die größer ist als die des Biege-Verdrillens.A preferred method for laying a wire in circular turns using a device according to the invention is characterized in that the additional twisting takes place at an angular velocity which is greater than that of the bending twisting.

Die Erfindung ist nachfolgend anhand der Zeichnung an zwei Ausführungsbeispielen näher erläutert, wobei Fig. 1 eine schematisch dargestellte Seitenansicht nach einer ersten Ausführungsform und Fig. 2 in zu Fig. 1 analoger Darstellung eine zweite Ausführungsform zeigen.The invention is explained in more detail below with reference to the drawing using two exemplary embodiments, FIG. 1 showing a schematically illustrated side view according to a first embodiment and FIG. 2 in a representation analogous to FIG. 1 showing a second embodiment.

Der von einem nicht dargestellten Drahtblock kommende heiße Draht 1 wird mittels einer Drahtfördereinrichtung 2, die von zwei einander gegenüberliegenden angetriebenen Walzen 3, 4 gebildet ist, einer Verdrilleinrichtung 5 zugeführt. Diese Verdrilleinrichtung 5 ist von einem U-förmig gebogenen Rohr 6 gebildet, dessen Ein- 7 und Austrittsende 8 etwa fluchtend zur durch die Drahtfördereinrichtung 2 festgelegten Drahtachse 9 ausgerichtet sind. Dieses Rohr 6 ist an seinen zueinander fluchtenden Enden 7, 8 drehbar in Lagern 10, 11 gelagert und mittels eines Antriebes 12 antreibbar. Der Innendurchmesser des Rohres 6 ist geringfügig größer als der Drahtdurchmesser.The hot wire 1 coming from a wire block, not shown, is fed to a twisting device 5 by means of a wire conveyor device 2, which is formed by two opposing driven rollers 3, 4. This twisting device 5 is formed by a U-shaped tube 6, the inlet 7 and outlet end 8 of which are aligned approximately with the wire axis 9 defined by the wire conveying device 2. This tube 6 is rotatably supported at its ends 7, 8 in bearings 10, 11 and can be driven by means of a drive 12. The inner diameter of the tube 6 is slightly larger than the wire diameter.

Nachfolgend an diese Verdrilleinrichtung 5 ist ein herkömmlicher Windungsleger 13 vorgesehen, der von einem räumlich gebogenen Legerohr 14 gebildet ist, das um die gerade Drahtachse 9 drehbar ist. Das Ende 15 des Legerohres 14, an dem der Draht 1 eintritt, ist etwa fluchtend zur von der Drahtfördereinrichtung 2 festgelegten geraden Drahtachse 9 ausgerichtet und mit diesem Ende mittels Lagern 16, 17 drehbar an einem nicht dargestellten Maschinengestell gelagert. Dieses Ende 15 ist weiters mit einer Antriebseinrichtung 18 gekoppelt.Following this twisting device 5, a conventional winding layer 13 is provided, which is formed by a spatially curved laying tube 14, which is rotatable about the straight wire axis 9. The end 15 of the laying tube 14, at which the wire 1 enters, is aligned approximately with and aligned with the straight wire axis 9 defined by the wire conveyor 2 End rotatably supported by bearings 16, 17 on a machine frame, not shown. This end 15 is also coupled to a drive device 18.

Das andere Ende 19 des Legerohres 14 ist kreisbogenförmig ausgebildet, wobei der Mittelpunkt 20 des Kreisbogens 21 auf der Drehachse des Legerohres 14 bzw. der damit identischen geraden Drahtachse 9 liegt. Zwischen den beiden Enden 15 und 19 weist das Legerohr 14 eine allmählich von der Achse 9 in den Kreisbogen 21 überleitende Form 22 auf.The other end 19 of the laying tube 14 is designed in the form of an arc of a circle, the center 20 of the arc 21 lying on the axis of rotation of the laying tube 14 or the straight wire axis 9 which is identical therewith. Between the two ends 15 and 19, the laying tube 14 has a shape 22 gradually transitioning from the axis 9 into the circular arc 21.

In Förderrichtung des Drahtes 1 ist nach dem Legerohr 14 ein Rollgang 23 vorgesehen, auf dem die Drahtwindungen 24 zu liegen kommen. Der Draht 1 wird auf diesem Rollgang 23 gekühlt und zu einer nachfolgenden Bundbildekammer transportiert.In the conveying direction of the wire 1, a roller table 23 is provided after the laying tube 14, on which the wire turns 24 come to rest. The wire 1 is cooled on this roller table 23 and transported to a subsequent bundle forming chamber.

Die dem Legerohr 14 vorgeordnete Verdrilleinrichtung 5 rotiert mit einer vorgewählten Winkelgeschwindigkeit, so daß der Draht mit einer bestimmten Verdrillung bereits in das Legerohr 14 eintritt. Hierdurch läßt sich die insgesamt auf den Draht 1 aufgebrachte Torsionsarbeit so weit erhöhen, daß die Drahtwindungen 24 ziemlich eng benachbart, d.h. mit einer geringen Steigung der von den Drahtwindungen 24 gebildeten Schraubenlinie, zu liegen kommen und eine Weiterförderung mit dem Rollgang 23 und ein Bundbilden problemlos vor sich gehen können.The twisting device 5 arranged upstream of the laying tube 14 rotates at a preselected angular speed, so that the wire already enters the laying tube 14 with a certain twisting. As a result, the total torsional work applied to the wire 1 can be increased to such an extent that the wire windings 24 are quite closely adjacent, i.e. come to rest with a slight slope of the helix formed by the wire windings 24, and further conveyance with the roller table 23 and bundling can proceed without problems.

Die Winkelgeschwindigkeit des Rohres 6 der Verdrilleinrichtung 5 ist größer gewählt als die des Legerohres 14. Durch Variieren des Verhältnisses der Winkelgeschwindigkeit des Rohres 6 der Verdrilleinrichtung 5 und der des Legerohres 14 läßt sich die Steigung 25 der von den Drahtwindungen 24 gebildeten Schraubenlinie variieren, so daß es möglich ist, eine ganz bestimmte, sehr kleine Steigung 25, die vorzugsweise dem Betrag nach dem Drahtdurchmesser entspricht oder nur geringfügig größer ist als dieser, einzustellen.The angular velocity of the tube 6 of the twisting device 5 is chosen to be greater than that of the laying tube 14. By varying the ratio of the angular velocity of the tube 6 of the twisting device 5 and that of the laying tube 14, the pitch 25 of the helix formed by the wire turns 24 can be varied so that it is possible to set a very specific, very small pitch 25, which preferably corresponds to the amount according to the wire diameter or is only slightly larger than this.

Gemäß der in Fig. 2 dargestellten Ausführungsform ist das Rohr 6 der Verdrilleinrichtung 5 als eine sich über 360° erstreckende Torsionsschlinge ausgebildet. Diese Ausführungsform weist den Vorteil auf, daß die von der Verdrilleinrichtung 5 zu leistende Biegearbeit gering ist.According to the embodiment shown in FIG. 2, the tube 6 of the twisting device 5 is an extension that extends over 360 ° Torsion loop formed. This embodiment has the advantage that the bending work to be performed by the twisting device 5 is low.

Die Erfindung beschränkt sich nicht auf die dargestellten Ausführungsbeispiele, sondern kann in verschiedener Hinsicht modifiziert werden. So ist beispielsweise die Ausbildung der Form des Rohres 6 der Verdrilleinrichtung 5 variierbar.The invention is not limited to the exemplary embodiments shown, but can be modified in various ways. For example, the shape of the tube 6 of the twisting device 5 can be varied.
