Description

Die Erfindung betrifft eine Vorrichtung zur Bildung von Schlingen aus einem, aus einer Walzdrahtstraße austretenden Drahtstrang mittels eines rotierenden Schlingenlegers und deren Ablage auf einen, während des Ablegens transportbewegten Förderer, bei der der Walzdrahtstraße eine Treibeinrichtung, ein Schlingenleger und ein Rollgang, ein Kettenförderer oder dergleichen nachgeordnet sind und Treibeinrichtung und ggfs. auch der Schlingenleger geneigt zur Horizontalen angeordnet sind.The invention relates to a device for forming loops from a wire strand emerging from a wire rod mill by means of a rotating sling layer and its storage a conveyor which is moved during discarding and in which the Wire rod mill a driving device, a looping device and a Roller table, a chain conveyor or the like are subordinate and Driving device and possibly also the sling layer inclined to the horizontal are arranged.

Moderne Drahtwalzstraßen arbeiten mit immer höher werdenden Endgeschwindigkeiten, insb. beim Walzen von Draht mit kleinem Durchmesser. Es werden dabei Endgeschwindigkeiten von mehr als 100 m/s erreicht. Andererseits werden auch immer stärkere Abmessungen gewalzt, bis zu Drahtdurchmessern von über ca. 25 mm.Modern wire rolling mills work at ever increasing top speeds, especially when rolling wire with a small diameter. The final speeds are more than 100 m / s reached. On the other hand, increasingly larger dimensions rolled, up to wire diameters of over approx. 25 mm.

Diese sehr unterschiedlichen Walzparameter bringen Probleme bei der Ablage der Drahtschlingen des fertig gewalzten Drahtes auf den Förderer mit sich.These very different rolling parameters cause problems with the Storage of the wire loops of the finished rolled wire on the Conveyor with himself.

Nach dem Stand der Technik ist der Schlingenleger meist mit einem Winkel von etwa 10° zur Horizontalen fest angeordnet und die, diesem vorgeordnete Treibeinrichtung entweder in der Horizontalen oder ebenfalls unter dem gleichen oder einem kleineren Winkel angeordnet. According to the state of the art, the sling layer is usually with one Angle of about 10 ° to the horizontal and the, this upstream driver either in the horizontal or also arranged at the same or a smaller angle.

Um eine einwandfreie Ablage der Schlingen von Drähten mit kleinem Durchmesser unter sehr hohen Geschwindigkeiten einerseits und von großen Drahtdurchmessern mit geringeren Geschwindigkeiten andererseits zu erzielen, wurde bereits ein Schlingenleger vorgeschlagen, dessen Neigung zur Horizontalen veränderbar war. Für hohe Drahtgeschwindigkeiten beträgt der Neigungswinkel dabei z.B. 10° und für niedrige Geschwindigkeiten bis zu 30°. Diese Lösung brachte jedoch die folgenden, erheblichen Nachteile mit sich: Die unterschiedlichen Neigungen bedingen entsprechend veränderte Abstände zu den horizontalen Führungsebenen, d.h. es müssen jeweils entsprechend angepaßte unterschiedliche Umlenkführungen eingesetzt werden. Weiter sind schwenkbare Tragkonstruktionen für die Treibeinrichtung und den Schlingenleger notwendig. Diese Tragkonstruktionen sind nicht nur technisch aufwendig, sondern auch bei hohen Geschwindigkeiten anfällig gegen Schwingungen.To ensure a perfect placement of the loops of wires with small Diameter at very high speeds on the one hand and of large wire diameters with lower speeds on the other hand a sling layer has already been proposed, whose inclination to the horizontal was changeable. For high wire speeds the angle of inclination is e.g. 10 ° and for low speeds up to 30 °. However, this solution brought the following significant disadvantages: The different Inclinations cause the distances to the horizontal to change accordingly Management levels, i.e. it must be adjusted accordingly different deflection guides can be used. Are further swiveling support structures for the driving device and the Loop layer necessary. These support structures are not only technically complex, but also at high speeds susceptible to vibrations.

Der Erfindung liegt die Aufgabe zugrunde, diese Vorrichtungen so zu verbessern, daß unter Vermeidung sowohl der schwenkbaren Tragkonstruktionen und der verschiedenen Umlenkführungen, als auch der Schwingungsanfälligkeit der Tragkonstruktionen, die einwandfreie Ablage der Schlingen von Drahtstärken mit kleinen und auch großen Durchmessern ermöglicht wird.The invention has for its object these devices to improve that while avoiding both the pivoting support structures and the different deflection guides, as well as the Susceptibility to vibrations of the supporting structures, the flawless Storage of the loops of wire gauge with small and also large ones Diameters is made possible.

Diese Aufgabe wird dadurch gelöst, daß bei fester Anordnung von Treibeinrichtung und Schlingenleger in einem vorbestimmten Neigungswinkel, die Transportebene des, die Schlingen aufnehmenden Förderers schwenkwinkelverstellbar zur Horizontalen ausgebildet ist. Die Schwenkachse für die Schwenkwinkelverstellung des Förderers wird zweckmäßig mit Abstand unter dessen, dem Schlingenaufnahmeende abgewandten Ende angeordnet, während der Antrieb der Treibeinrichtung zweckmäßig bspw. über druckregelbare Pneumatik-KolbenZylinder-Aggregate regelbar und die Position der Tragrollen über Stellelemente, wie Stellschrauben einstellbar ist. This object is achieved in that with a fixed arrangement of Drive device and sling layer at a predetermined angle of inclination, the transport level of the conveyor taking up the slings is adjustable adjustable to the horizontal. The Swivel axis for the swivel angle adjustment of the conveyor expediently at a distance below the loop end arranged opposite end, while driving the driver Expedient, for example, via pressure-adjustable pneumatic piston-cylinder units adjustable and the position of the idlers via adjusting elements, how adjusting screws can be adjusted.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeisplels näher erläutert.The invention is based on the exemplary embodiment shown in the drawing explained in more detail.

Die Zeichnung zeigt die Anordnung von Treibeinrichtung, Schlingenleger und Förderer in schematischer Darstellung.The drawing shows the arrangement of the drive device, sling layer and conveyor in a schematic representation.

Hinter dem Ausgang der nicht dargestellten Walzdrahtstraße, aus der der Drahtstrang ST in Richtung des eingezeichneten Pfeiles austritt, ist die Treibeinrichtung TE mit den Treibrollen 1 und 2 angeordnet. Die gemeinsame Achsebene x-x liegt dabei in einem Winkel α zur Vertikalen. Hinter der Treibeinrichtung TE ist der Schlingenleger SL angeordnet. Die Rotationsachse y-y des Legerohres 3 verläuft dabei in einem Winkel β zur Horizontalen, während der Legearm 3a des Legerohres 3 in einem Winkel δ zur Rotationsebene z-z des Legearms liegt. Der Förderer, hier ein Rollgang 4, ist um die Schwenkachse 5, die sich mit einem Abstand d unterhalb des, dem Schlingenaufnahmeende 4a abgewandten Endes 4b des Rollgangs 4 befindet, in einer vertikalen Ebene zwischen einer oberen Hoch-Position H, die in vollen Linien angedeutet ist und einer Tief-Position T, die in unterbrochenen Linien angedeutet ist, schwenkbar.Behind the exit of the wire rod mill, not shown, from the the wire strand ST emerges in the direction of the arrow shown, the drive device TE with the drive rollers 1 and 2 is arranged. The common axis plane x-x lies at an angle α to Vertical. The looping device is behind the driving device TE SL arranged. The axis of rotation y-y of the laying tube 3 runs thereby at an angle β to the horizontal, while the laying arm 3a of the laying tube 3 at an angle δ to the plane of rotation z-z of the Legearms lies. The conveyor, here a roller table 4, is around Pivot axis 5, which is at a distance d below that Loop receiving end 4a of the opposite end 4b of the roller table 4 located in a vertical plane between an upper high position H, which is indicated in full lines and a low position T, which is indicated in broken lines, pivotable.

Die Treibrollen 1, 2 drehen vor Einlauf des Anfangs des Drahtstranges mit etwas höheren Drehzahlen als die der erwarteten Geschwindigkeit des Drahtes entsprechende, und ihr Öffnungsspalt ist geringfügig größer bemessen als der Drahtdurchmesser. Die Treibrollen 1, 2 werden, wenn der Anfang des Drahtes diese passiert hat und durch die nicht dargestellte Führung hinter den Treibrollen 1, 2 nach unten gelenkt wurde, geschlossen. Die geneigte Anordnung der gemeinsamen Achsebene der Treibrollen 1, 2 bewirkt neben dem Treib- auch einen Biegeeffekt auf den Draht. Dieser Biegeeffekt ist bei Draht mit großem Durchmesser größer, weil der Hebelarm, mit dem die Treibrollen 1, 2 auf den in einer waagerechten Ebene einlaufenden Draht wirken, größer ist, d.h. das Biegemoment vergrößert sich mit steigendem Drahtdurchmesser. Dies erleichtert die Umlenkung des Drahtes und vermindert die dabei entstehenden Reibungsverluste. Neben der beschriebenen Umlenkarbeit müssen die Treibrollen 1, 2 auch die Enden von Drähten mit großem Durchmesser, nachdem diese die Drahtstraße verlassen haben, antreiben und zur Kompensation der Arbeit im Legerohr 3 beschleunigen. Dies wird durch die geneigte Anordnung der Treibrollen 1, 2 unterstützt.The drive rollers 1, 2 rotate before the beginning of the wire strand at slightly higher speeds than the expected speed corresponding to the wire, and its opening gap is slight dimensioned larger than the wire diameter. The driving rollers 1, 2 when the beginning of the wire has passed through and through the guide, not shown, behind the drive rollers 1, 2 was steered down, closed. The inclined arrangement of the common Axial plane of the drive rollers 1, 2 causes not only the drive but also a bending effect on the wire. This bending effect is with wire large diameter larger because of the lever arm with which the Driving rollers 1, 2 on the incoming in a horizontal plane Wire, is larger, i.e. the bending moment increases with increasing wire diameter. This facilitates the redirection of the Wire and reduces the resulting friction losses. In addition to the described deflection work, the drive rollers 1, 2 even the ends of large diameter wires after this have left the wire mill, drive and to compensate for the Accelerate work in laying tube 3. This is due to the inclined Arrangement of the drive rollers 1, 2 supported.

Die Schlingen werden zunächst im Legearm 3a des Legerohres 3 gebildet, der auch den Durchmesser der Schlinge bestimmt. Der Austritt der Schlingen in einem Winkel β zur Rotationsebene bewirkt eine Bewegung der austretenden Schlingen in Richtung der Rotationsachse y-y des Legearms 3a, die bei hohen Geschwindigkeiten des Drahtes bis zu 5 m/s erreicht. Diese Geschwindigkeiten werden bei Drähten mit kleinem Durchmesser erreicht. Diese weisen im walzwarmen Zustand eine geringe Stabilität auf. Um trotz dieser geringen Stabilität eine einwandfreie Ablage der Schlingen auf dem Rollgang 4 zu erreichen, wird dieser in die mit T bezeichnete Tief-Position abgesenkt. In dieser bremst der Rollgang 4 die aufgelegten Schlingen nur in einem geringen Maße ab, weshalb es nicht zur Verformung des Drahtes kommt.The loops are first formed in the laying arm 3a of the laying tube 3, which also determines the diameter of the sling. The exit the loops at an angle β to the plane of rotation causes one Movement of the emerging loops in the direction of the axis of rotation y-y of the laying arm 3a, the wire at high speeds up to 5 m / s reached. These speeds are at wires achieved with a small diameter. These show in the warm condition low stability. To despite this low stability to achieve a perfect placement of the slings on the roller table 4, it is lowered into the low position labeled T. In this the roller table 4 only brakes the slings in place a small amount, which is why it does not deform the wire is coming.

Beim Legen der Schlingen von Drähten mit größerem Durchmesser ist deren Bewegungsgeschwindigkeit in Richtung der Rotationsachse y-y des Legearms 3a gering. Die Schlingen weisen wegen des größeren Drahtdurchmessers eine höhere Steifigkeit auf. Der Rollgang 4 wird deshalb in diesem Fall in die Hoch-Position H geschwenkt. Damit werden die Schlingen, unmittelbar nachdem sie den Legearm 3a verlassen haben, erheblich stärker abgebremst und damit das rechtzeitige Auflegen auf dem Rollgang 4 gewährleistet.When laying the loops of wires with larger diameter is their speed of movement in the direction of the axis of rotation y-y of the laying arm 3a low. The slings point because of the larger one Wire stiffness. The roller table 4 will therefore pivoted to the high position H in this case. In order to the loops immediately after leaving the laying arm 3a have slowed down considerably more and thus the timely Hanging on the roller table 4 guaranteed.

Die Lage der Schwenkachse 5 des Rollgangs 4 ist so gewählt, daß beim Heben bzw. Senken die Position der ersten Rollgangsrolle 4a stets im günstigsten Abstand vom Legearm 3a bzw. dessen festen Führungsring 6 bleibt.The position of the pivot axis 5 of the roller table 4 is selected so that when Always raise or lower the position of the first roller table roller 4a at the best distance from the laying arm 3a or its fixed guide ring 6 remains.
