Abstract

The coil winder has a laying tube (LR) for rapidly moving wire, consisting of a carrier shell (TH), fitted in a carrier casing (TG) in two bearings (EL, HL). The wire insertion sector (LRE) receives the laying tube. The carrier shell is connected to a tube holder (RH) which receives the wire guiding-out sector (LRA) of the laying tube.

Description

Die Erfindung betrifft einen Windungsleger mit Legerohr für schnellbewegten Walzdraht, der aus einer, horizontal in zwei beabstandeten, in einem Traggehäuse angeordneten Lagern gelagerten, den Drahteinführabschnitt des Legerohres aufnehmenden, drehantreibbaren Traghülse besteht, mit deren, dem Drahteinführabschnitt abgewandten Ringstim, frei überhängend, ein, dem Drahtausführabschnitt des Legerohres aufnehmender Rohrhalter verbunden ist.The invention relates to a winding layer with a laying tube for rapidly moving wire rod, which consists of a rotationally drivable support sleeve, which is mounted horizontally in two spaced bearings arranged in a support housing and accommodates the wire insertion section of the laying tube, with its ring stimulus, freely overhanging, facing away from the wire insertion section. is connected to the wire lead-out portion of the laying tube receiving tube holder.

Bei Windungslegem dieser Bauweise wird der, mit hoher Geschwindigkeit aus der Drahtwalzstraße kommende Walzdraht in dem; in der Drehachsmitte der Traghülse angeordneten Einführabschnitt des Legerohres ein- und von diesem zum Ausführabschnitt geführt, der mit radialem Abstand von der Drehachsmitte in einem Kreis umläuft und dabei den aus seiner Mündung austretenden Walzdraht in kreisförmigen Windungen auf einen Weiterförderer abwirft. (EP-A2 965 396 und EP-A 679 453)With this type of winding, the wire rod coming out of the wire rolling mill at high speed is placed in the; arranged in the center of the axis of the support sleeve insertion section of the laying tube and guided by this to the execution section, which rotates in a circle at a radial distance from the center of the axis of rotation and thereby throws the wire rod emerging from its mouth in circular turns onto a further conveyor. (EP-A2 965 396 and EP-A 679 453)

Da der Walzdraht von modernen Drahtwalzstraßen mit hohen Geschwindigkeiten ausgebracht wird, muss der Windungsleger mit entsprechend hohen Drehzahlen betrieben werden. Das Legerohr, dass den in einer linearen Bewegung zugeführten Draht in eine Kreiswindung bringt, muss dabei von dem Rohrhalter möglichst formstabil gehalten werden, zumal die besondere Führungsform des Legerohres zu einer Konzentration der umlaufenden Massen an dem, am weitesten überhängenden Abschnitt des Rohrhalters führt.Since the wire rod is brought out at high speeds by modern wire rolling mills, the coiler must be operated at correspondingly high speeds. The laying tube, which brings the wire fed in a linear movement into a circular turn, must be kept as dimensionally stable as possible by the tube holder, especially since the special guiding form of the laying tube leads to a concentration of the circulating masses on the most overhanging section of the tube holder.

Bei dieser Ausbildung, die in der Regel ein Radiallager als Loslager und ein Festlager aufweist ergibt sich durch den Überhang des Rohrhalters eine, im wesentlichen richtungskonstante Durchbiegung der Traghülse zwischen beiden Lagern, verbunden mit einer, aus dem Umlauf herrührenden Umwucht. Diese beiden scheinungen führen beim Betreiben des Windungslegers infolge der hohen und ständig erhöhten Walzgeschwindigkeiten der Walzdrahtstraße zu biegekritischen Drehzahlen, bei deren Überschreitung gefährliche Pendelschwingungen von Rohrhalter und Legerohr auftreten können, die darüber hinaus häufig Umlaufbewegungen der Lager und auch Lagerermüdungen mit sich bringen.In this design, which usually has a radial bearing as a floating bearing and a fixed bearing, the overhang of the tube holder results in a substantially constant deflection of the support sleeve between the two bearings, connected with a balance resulting from the rotation. These two phenomena lead to critical bending speeds when operating the lay-up device due to the high and constantly increasing rolling speeds of the wire rod mill.If exceeded, dangerous pendulum vibrations of the pipe holder and the laying pipe can occur, which in addition frequently cause circulating movements of the bearings and also bearing fatigue.

Der Erfindung liegt die Aufgabe zugrunde, Einrichtungen zu schaffen, mit denen diesen Erscheinungen, insb. den Pendelschwingungen und deren Folgeerscheinungen begegnet werden kann.The invention has for its object to provide devices with which these phenomena, in particular the pendulum vibrations and their consequences can be countered.

Diese Aufgabe wird durch eine, mit dem Traggehäuse verbundene, zwischen den beiden Lagern einen Abschnitt der Traghülse radial beaufschlagende Druckvorrichtung gelöst. Die Druckvorrichtung kann dabei erfindungsgemäß aus einem einstellbaren feder-, elektro- oder hydromechanisch bewegten Träger einer Mehrzahl von Druckrollen bestehen, die auf den zylindrischen Abschnitt der Traghülse auflegbar sind. Eine weitere Möglichkeit der Ausbildung der Druckvorrichtung kann aus einer, den zylindrischen Abschnitt der Traghülse umfassenden öldruckbeaufschlagbaren, geschlossenen, (aus Manfred Beek "Werkzeugmaschine", Kapitel 5.6.3 Bild 5-199; auch aus US-PS 4,036,030) Druckbüchse für den einstellbaren Aufbau eines, etwa vertikal gerichteten hydrostatischen und/oder hydromechanischen Drucks auf den Traghülsenabschnitt bestehen. Die Druckbüchse kann dabei in bekannter Weise mit konisch verlaufenden Innenwandungen ausgestattet und auf dem Traghülsenabschnitt einstellbar axial verschiebbar sein, um den Angriffspunkt des Drucks in axialer Richtung verstellbar zu positionieren. Eine weitere erfindungsgemäße Möglichkeit besteht darin, die Druckvorrichtung als ein Magnetlager (DE-A1 684 093) auszubilden, das den zylindrischen Traghülsenabschnitt umfasst, wobei dessen Magnetkräfte richtungs- und belastungssteuerbar sind. Richtig kann die Druckvorrichtung aus einem achsradial druckbeaufschlagbaren Gleidlager bestehen, das ggf. einstellbar axial verschiebbar ist.This object is achieved by a pressure device, which is connected to the support housing and acts radially on a section of the support sleeve between the two bearings. According to the invention, the printing device can consist of an adjustable spring, electro-mechanical or hydromechanically moved carrier of a plurality of pressure rollers which can be placed on the cylindrical section of the support sleeve. A further possibility for the design of the pressure device can be made from a closed pressure sleeve for the adjustable structure (from Manfred Beek "Machine Tool", Chapter 5.6.3, Fig. 5-199; also from US Pat. No. 4,036,030) comprising the cylindrical section of the support sleeve a, approximately vertically directed hydrostatic and / or hydromechanical pressure on the support sleeve section. The pressure sleeve can be equipped in a known manner with conical inner walls and can be axially displaceably adjustable on the support sleeve section in order to position the pressure application point in an axially adjustable manner. Another possibility according to the invention is to use the printing device as a magnetic bearing (DE-A1 684 093), which comprises the cylindrical support sleeve section, the magnetic forces of which can be controlled in terms of direction and load. Correctly, the pressure device can consist of an axially radial pressure bearing which can be axially displaceable if necessary.

Neben der, mit diesen Druckeinrichtungen erreichten Beseitigung unerwünschter Zusatzbelastungen der Lager, insb. des an den Rohrhalter angrenzenden Lagers der Traghülse wird auch der Schwingungspegel erheblich reduziert; und lässt einen störungslosen Betrieb auch bei weiter steigenden Walzgeschwindigkeiten der Drahtwalzstraße zu.In addition to the elimination of undesirable additional loads on the bearings, in particular the bearing of the support sleeve adjoining the pipe holder, the vibration level is also considerably reduced; and allows trouble-free operation even with further increasing rolling speeds of the wire rolling mill.

Der zylindrische Abschnitt THZ der Traghülse TH weist drehachsmittig einen Einführungsdurchgang ED für den, aus der, nicht dargestellten Drahtwalzstraße herangeführten Walzdraht auf. An die Ringstim RS des kegelförmigen Abschnitts THK der Traghülse TH ist ein Rohrhalter RH angeflanscht. Das Legerohr LR ist mit seinem Drahteinführabschnitt LRE mit dem Einführdurchgang ED verbunden, und sein Drahtausführabschnitt LRA wird von dem Rohrhalter RH getragen.As can be seen from FIG. 1, the winding layer is composed of a support housing TG in which a support sleeve TH is arranged, which here has a cylindrical section THZ in an insertion bearing EL and a conical section THK adjoining this cylindrical section THZ by doing Main camp HL stores.

The carrier TR is moved in a manner not shown by spring assemblies or electromechanically or electrohydraulically operating devices.

Aus Fig. 3 geht eine Ausbildungsform der Druckvorrichtung hervor, bei der der Druck auf den zylindrischen Traghülsenabschnitt THZ mit Hilfe einer, diesen Abschnitt umfassenden Druckbüchse DB besteht, in der auf nicht dargestellte Weise ein einstellbarer, vertikal gerichteter hydromechanischer oder hydrostatischer Druck aufbaubar ist, dessen Verteilung mit dem Diagramm D angedeutet ist.From Fig. 3 shows an embodiment of the printing device, in which the pressure on the cylindrical support sleeve section THZ with the help of a, this section comprehensive pressure sleeve DB, in which an adjustable, vertically directed hydromechanical or hydrostatic pressure can be built up in a manner not shown, the Distribution is indicated with the diagram D.
