Description

Die Erfindung betrifft eine Anlage zum Walzen von Draht, bei der einem Drahtwalzwerk eine Kühlstrecke, umfassend aufeinander folgende Förderabschnitte zum Transportieren des auf den Fördermitteln zu Windungen ausgefächerten Drahtes, und ein die Drahtwindungen aus der Kühlstrecke abnehmender sowie in eine Bundbildevorrichtung abwerfender Einlegeförderer nachgeschaltet sind.The invention relates to a system for rolling wire, in which a wire mill downstream of a cooling section, comprising successive conveyor sections for transporting the fanned out on the conveyors to turns wire, and a wire turns from the cooling section decreasing and dropping into a coil forming device drop-in conveyor.

Damit sich beim Walzen von Draht die entsprechenden Materialeigenschaften erreichen lassen, werden sowohl dünner Draht - mit Durchmessern bis etwa 20 mm - als auch dicker Draht - mit Durchmessern bis etwa 50 mm - nach dem Austritt aus der mehrgerüstigen Fertigstraße eines Walzwerkes verschiedenen Kühlprozessen unterworfen. Diese umfassen für dünnen Draht, den sogenannten Stelmor-Produkten, und dicken Draht, den sogenannten Garrett-Produkten, entweder eine Standard- bzw. forcierte Kühlung, z.B. für mittel- bis hochgekohlte Kohlenstoffstähle und Austenite, eine verzögerte Kühlung, beispielsweise für niedrig gekohlte C-Stähle, Schraubenstähle, Federstähle und Schweißdrähte, oder eine langsame Kühlung, z.B. für Werkzeugstähle und Schnellarbeitsstähle. Diese Voraussetzungen lassen sich durch eine entsprechend gestaltete Kühlstrecke schaffen.In order to achieve the appropriate material properties when rolling wire, both thin wire - with diameters up to about 20 mm - and thick wire - with diameters up to about 50 mm - after exiting the multi-stand finishing mill of a rolling mill are subjected to different cooling processes. These include for thin wire, the so-called Stelmor products, and thick wire, the so-called Garrett products, either a standard or forced cooling, e.g. for medium to high carbon carbon steels and austenites, delayed cooling, for example for low carbon C steels, helical steels, spring steels and welding wires, or slow cooling, e.g. for tool steels and high speed steels. These conditions can be created by a correspondingly designed cooling section.

Durch die EP 0 504 655 B1 ist bei einer Anlage der eingangs genannten Art zur Stelmor-Kühlung des dünnen Drahtes bekannt geworden, das in Windungen auf einem Förderer ausgefächerte Drahtprodukt mit Hilfe von Kühlluft und geöffneten bzw. geschlossenen oder teils offenen und teils geschlossenen Deckeln bzw. Hauben der Kühlstrecke oder mittels Warmhalte-Töpfen zu kühlen. Das Abkühlen von zu Bunden gewickelten dicken Draht lässt sich an der Umgebungsluft bzw. durch Ventilatoren im Bereich des Längstransportes der Kühlstrecke, durch den Einsatz von Wasserhaspeln, das Aufsetzen von isolierten Hauben, mittels Warmhalte-Töpfen oder in Isolationskammern erreichen. Auf diese Weise ist es möglich, vor allem dann, wenn eine große Qualitätspalette gewünscht wird, wie insbesondere bei Edelstahl-Produkten, eine den Anforderungen an das Produkt entsprechende Kühlung vorzunehmen.By the EP 0 504 655 B1 is known in a system of the type mentioned for Stelmor cooling of the thin wire, the fanned in turns on a conveyor wire product with the help of cooling air and open or closed or partially open and partially closed lids or hoods of the cooling section or by holding To cool pots. The cooling of wound into coils thick wire can be in the ambient air or by fans in the area of the longitudinal transport of the cooling section, by the use of water reels, the placement of insulated hoods, reach by means of holding pots or in isolation chambers. In this way, it is possible, especially when a large range of quality is desired, as in particular for stainless steel products, make a cooling requirements for the product.

Dem Drahtwalzwerk dieser bekannten Anlagen ist eine Bundbildevorrichtung im Anschluß an die Kühlstrecke nachgeordnet, in die die Drahtwindungen von einem Einlegeförderer, der als Überbrückungsglied zwischen dem letzten Förderabschnitt der Kühlstrecke und der Bundebildevorrichtung angeordnet ist, abgeworfen werden. Die auf diese Weise erreichten Drahtbunde werden entnommen, z.B. mit einer Hakenbahn einer Ringpreß- und Bindestation zugeführt, und von dort weiter verteilt.The wire rolling mill of these known systems downstream of a coil forming device is connected downstream of the cooling section, in which the wire turns of an infeed conveyor, which is arranged as a bridging member between the last conveyor section of the cooling section and the bundle forming device, are dropped. The wire bundles thus obtained are removed, e.g. supplied with a hook path of a Ringpreß- and binding station, and further distributed from there.

Die in der Praxis bekannten Einlegeförderer, die als Fördermittel z. B. Rollgangsrollen, von denen zumindest einige angetrieben sind, Transportbänder oder Transportketten besitzen, sind ortsfest mit dem Fundament verankert. Im Übergangsbereich zur Bundebildevorrichtung ist ihnen als separater Bestandteil ein Stummelrollensegment zugeordnet, das die Bundbildevorrichtung teilumfänglich umgreift und paarweise, im Abstand gegenüberliegende Stummelrollen aufweist. Das Stummelrollensegment ist in verschiedenen Bewegungsrichtungen verstellbar und mittelbar darüber sind es auch die Stummelrollen. Damit soll ein gezielteres Abwerfen der Drahtringe in die Bundbildevorrichtung ermöglicht werden. Diesem Zweck dienen auch die Stummelrollen, die keine einstückig durchgehenden, sondern Rollen mit bestimmter Teillänge sind. Jeweils ein Paar gegenüberliegender Stummelrollen besitzt die gleiche Teillänge, wobei diese Teillängen von Rollenpaar zu Rollenpaar hin zur Bundbildevorrichtung kürzer werden.The well-known in-feed conveyor, as a conveyor z. B. roller table rollers, of which at least some are driven, conveyor belts or transport chains, are anchored stationary with the foundation. In the transition region to Bundebildevorrichtung they are assigned as a separate part of a stub roll segment, which surrounds the Bundbildevorrichtung partumfänglich and has pairwise, spaced opposite stub rolls. The stub roll segment is adjustable in different directions of movement and indirectly it is also the stub rolls. This is intended to enable a more targeted ejection of the wire rings into the framing device. This purpose is also the stub roll, which are not one-piece continuous, but rollers with a certain part length. In each case a pair of opposing stub rolls has the same part length, these part lengths from pair of rollers to pair of rollers towards the framing device are shorter.

Es hat sich im Betrieb gezeigt, daß bei den bekannten Anlagen die Überleitung der Drahtwindungen aus der Kühlstrecke auf den Einlegeförderer und von diesem auf das endseitige, der Bundbildevorrichtung unmittelbar vorgeschaltete Stummelrollensegment proplematisch ist. Zwischen diesen Bauteilen sind nämlich Lücken unvermeidlich, die die Struktur der dicht aufeinanderfolgenden und einander überlappenden Drahtwindungen nachteilig beeinflussen, was das Einlegen bzw. Abwerfen in die Bundbildevorrichtung beeinträchtigt.It has been shown in operation that in the known systems, the transfer of the wire turns from the cooling section to the feed conveyor and from this on the end, the Bundbildevorrichtung immediately upstream stub roll segment is proplematically. Namely gaps are inevitable between these components, which adversely affect the structure of the closely spaced and overlapping wire windings, which affects the insertion or dropping into the framing device.

Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße Anlage ohne diese Nachteile zu schaffen, insbesondere einen ungestörten Transport mit sicherer Weiterleitung der Drahtwindungen von der einen auf die andere Transportstrecke zu ermöglichen und das Einlegen der Drahtwindungen in die Bundbildevorrichtung zu verbessern.The invention is therefore an object of the invention to provide a generic system without these disadvantages, in particular to allow undisturbed transport with safe forwarding of the turns of wire from one to the other transport route and to improve the insertion of the wire turns in the Bundbildevorrichtung.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der gesamte Einlegeförderer linear verschieblich ausgebildet ist. Durch den vorteilhaft in und gegen die Förderrichtung verschiebbaren Einlegeförderer lässt sich dieser gezielt stets so positionieren, daß zwischen den einzelnen Transportstrecken keine Lücken auftreten, so daß die Ausfächerung der Drahtwindungen nicht verzerrt wird und sie mit ihrer ringförmigen Struktur in die Bundbildevorrichtung eingelegt werden können. Damit läßt sich eine optimierte Windungsablage und somit verbesserte Ringform erreichen.This object is achieved in that the entire feed conveyor is formed linearly displaceable. By advantageously displaceable in and against the conveying direction feed conveyor can this targeted always position so that between the individual transport paths no gaps occur, so that the fanning out of the wire turns is not distorted and they can be placed with their annular structure in the Bundbildevorrichtung. Thus, an optimized Windungsablage and thus improved ring shape can be achieved.

Das wird nach einer bevorzugten Ausführung der Erfindung dadurch weiter begünstigt, daß mit dem Einlegeförderer im Abwurfbereich zur Bundbildevorrichtung ein paarweise im Abstand gegenüber liegende Stummelrollen aufweisendes Stummelrollensegment fest verbunden ist. Damit lässt sich eine einheitliche, gleichzeitige gemeinsame Verschiebung und Positionierung aller sich der Kühlstrecke anschließenden Förderstrecken erreichen. Außerdem kann auch zwischen dem Einlegeförderer und dem Stummelrollensegment keine Lücke mehr auftreten.This is favored according to a preferred embodiment of the invention further characterized in that the infeed conveyor in the discharge area to the collar forming device a pairwise spaced opposite stub rolls roles stub roll segment is firmly connected. This makes it possible to achieve a uniform, simultaneous joint displacement and positioning of all the conveyor sections that follow the cooling section. In addition, no gap can occur between the feed conveyor and the stub roll segment.

Ein Vorschlag der Erfindung sieht vor, daß der Einlegeförderer in Förderrichtung ansteigend angeordnet und mit einem hinteren, von der Bundbildevorrichtung abgewandten Endabschnitt unter einen letzten Förderabschnitt der Kühlstrecke tauchend verschiebbar ist. Die somit gestufte Übergabe und der sich anschießende ansteigende Transportweg verbessern die Abwurf- bzw. Einlegevoraussetzungen und erlauben es, mit unterschiedlichen Geschwindigkeiten zu arbeiten.A proposal of the invention provides that the infeed conveyor is arranged ascending in the conveying direction and with a rear, facing away from the collar forming device end portion under a last conveying section of the cooling section is submersible slidably. The thus graded transfer and the subsequent rising transport path improve the dropping or insertion requirements and allow it to work at different speeds.

Das Einlegen und Überleiten der Drahtwindungen in die Bundbildevorrichtung wird dadurch noch weiter verbessert, daß der letzte Förderabschnitt der Kühlstrecke ebenfalls mit paarweisen, einander im Abstand gegenüber liegenden Stummelrollen ausgebildet ist.The insertion and passage of the wire turns in the coil forming device is further improved by the fact that the last conveyor section of the cooling section is also formed with pairs, each other at a distance opposite stub rolls.

Nach einer Ausgestaltung der Erfindung wird vorgeschlagen, daß der Einlegeförder auf ortsfesten Führungen, z.B. Schienen oder dergleichen Laufflächen, angeordnet ist.According to one embodiment of the invention it is proposed that the infeed conveyor on fixed guides, e.g. Rails or the like running surfaces, is arranged.

Damit sich der Einlegeförderer durch Verschiebung exakt positionieren lässt, wird vorgeschlagen, daß er mit zumindest einem Linearantrieb ausgebildet ist. Der bzw. die beispielsweise weggeregelt überwachten Linearantriebe können hydraulische, mechanische oder elektromechanische Verstellmittel sein. Es können z-B. Zahnstangen, Ritzelkombinationen, Seile, Ketten, Zahnriemen, Schraubgetriebe oder dergleichen zum Einsatz kommen.So that the insertion conveyor can be positioned exactly by displacement, it is proposed that it is formed with at least one linear drive. The linear actuators which are controlled in a path-controlled manner, for example, can be hydraulic, mechanical or electromechanical adjusting means. It can z-B. Racks, pinion combinations, ropes, chains, timing belts, helical gears or the like are used.

Bei einer in ihrer Gesamtheit nicht dargestellten Anlage zum Walzen von Draht schließt sich einem Drahtwalzwerk eine Kühlstrecke 1 und dieser als Überbrückungsglied zu einer Bundbildevorrichtung bzw. -kammer 2 ein als Rollgangsförderer ausgebildeter Einlegeförderer 3 an (vgl. Fig. 5). Die Kühlstrecke 1 besteht aus mehreren, von Hauben 4, Deckeln oder dergleichen abgedeckten Förder- bzw. Rollgangsabschnitten 5 mit zahlreichen aufeinander folgenden, in einem Traggestell gelagerten Rollgangsrollen 6, von denen zumindest einige angetrieben sind (vgl. Fig. 3), und im Ausführungsbeispiel einem in Förderrichtung gemäß Pfeil 7 letzten, festen Förder- bzw. Rollgangsabschnitt 8 mit darin angeordneten Stummelrollen 9; diese könnten alternativ auch durchgehend ausgebildet sein.In a system for rolling wire, not shown in its entirety, a wire rolling mill is followed by a cooling section 1 and this as a bridging link to a collar forming device or chamber 2 as an infeed conveyor 3 designed as a roller table conveyor (compare Fig. 5). The cooling section 1 consists of several, covered by hoods 4, covers or the like conveyor or roller table sections 5 with numerous successive, mounted in a support frame roller conveyor rollers 6, of which at least some are driven (see Fig. 3), and in the embodiment one in the conveying direction according to arrow 7 last, solid conveyor or roller table section 8 with stub rolls 9 arranged therein; these could alternatively be designed continuously.

Der in dem mehrere Gerüste besitzenden Drahtwalzwerk gewalzte Draht wird hinter dem letzten Walzgerüst und nachdem er beispielsweise einen Wasserkasten durchlaufen und von einer Schere unterteilt worden ist, von einem Windungsleger in Form von spiral- bzw. ringförmigen Drahtwindungen 10 (vgl. Fig. 2) auf den Rollgangsrollen 6 abgelegt. Aus der Kühlstrecke 1 gelangen die Drahtwindungen 10 zum Weitertransport auf Rollgangsrollen 11, von denen ebenfalls einige angetrieben sind, des Einlegeförderers 3. Über dessen transportendseitiges Vorderende werden sie in die kammerartige Bundbildevorrichtung 2 eingelegt bzw. abgeworfen, wobei ein Dorn 12 (vgl. Fig. 5) die Drahtwindungen zu einem fertigen Ringbund zentriert.The wire rolled in the multi-stand wire rolling mill is fed behind the last stand and, after passing through, for example, a water box and subdivided by a pair of scissors, from a coiler in the form of helical windings 10 (see Fig. 2) the roller table rollers 6 stored. From the cooling section 1 enter the wire turns 10 for further transport on roller table rollers 11, some of which are driven, the infeed conveyor 3. About the transport end side front end they are inserted or dropped into the chamber-like coil forming device 2, wherein a mandrel 12 (see Fig. 5) the wire turns to a finished Centered collar.

Damit der Walzdraht bzw. die Drahtwindungen 10 ungehindert und insbesondere lückenlos aus der Kühlstrecke 1 auf den Einlegeförderer 3 und von diesem in die Bundbildevorrichtung 2 übergeleitet werden können, ist der Einlegeförderer 3 insgesamt linear verschieblich in Richtung des Doppelpfeils 13 (vgl. die Fig. 1 und 5) auf ortsfesten Führungen 14 (vgl. Fig. 3) angeordnet. Der Einlegeförderer 3 kann damit in Bezug einerseits auf den letzten Rollgangsabschnitt 8 der Kühlstrecke 1 und andererseits die Bundbildevorrichtung 2 durch Linearverschiebung exakt und insbesondere ohne Lücke zur Kühlstrecke 1 positioniert werden.In order that the wire rod or the wire windings 10 can be transferred from the cooling section 1 to the infeed conveyor 3 and from there into the coil forming device 2 unhindered and in particular, the infeed conveyor 3 is linearly displaceable in the direction of the double arrow 13 (see FIGS and 5) on stationary guides 14 (see Fig. 3). The infeed conveyor 3 can thus be positioned in relation to the last roller table section 8 of the cooling section 1 on the one hand and the coil forming device 2 on the other hand by linear displacement exactly and in particular without gap to the cooling section 1.

In Fig. 4 ist eine Ausführung dargestellt, bei der der Einlegeförderer 3 unter einem geringen Neigungswinkel in Förderrichtung 7 ebenso leicht ansteigend wie die Kühlstrecke 1 ausgebildet ist und mit seinem hinteren, von der Bundbildevorrichtung 2 abgewandten Endabschnitt 15 bis unter den letzten Rollgangsabschnitt 8 der Kühlstrecke 1 verschoben ist.In Fig. 4, an embodiment is shown, in which the infeed conveyor 3 is formed at a slight angle in the conveying direction 7 as slightly rising as the cooling section 1 and with its rear, facing away from the Bundbildevorrichtung 2 end portion 15 to below the last roller table section 8 of the cooling section 1 is moved.

Zum Verschieben des Einlegeförderers 3 greift an diesen zumindest ein Linearantrieb 16 an, wie in den Fig. 1 und 5 dargestellt, der sich in mannigfaltiger Ausführung, z.B. hydraulisch, mechanisch oder elektromechanisch, vorsehen lässt.For moving the infeed conveyor 3, at least one linear drive 16 acts thereon, as shown in FIGS. 1 and 5, which can be constructed in a variety of ways, e.g. hydraulic, mechanical or electromechanical, can provide.

Wie sich den Fig. 2 und 4 entnehmen lässt, ist am vorderen Ende des Einlegeförderers 3 im Abwurfbereich zur Bundbildevorrichtung 2 ein mit dem Einlegeförderers 3 fest verbundenes Stummelrollensegment 17 angeordnet. Dieses besitzt in paarweiser Anordnung einander gegenüber liegende Stummelrollen 18a bis 18d, wobei jede Stummelrolle 18a bis 18d eines Rollenpaares in einer separaten Rollensegmenthälfte 19 bzw. 20 gelagert ist. Die Rollensegmenthälften 19 bzw. 20 sind gemäß Doppelpfeil 21 (vgl. Fig. 2) an dem Einlegeförderer 3 quer zur Förderrichtung 7 verschiebbar befestigt.As can be seen from FIGS. 2 and 4, a stub roll segment 17 fixedly connected to the infeed conveyor 3 is arranged at the front end of the infeed conveyor 3 in the discharge area for the bundle forming device 2. This has in paired arrangement opposing stub rolls 18a to 18d, each stub roll 18a to 18d of a pair of rollers in a separate role segment half 19 and 20 is stored. The roller segment halves 19 and 20, respectively, are slidably mounted transversely to the conveying direction 7 on the insertion conveyor 3 in accordance with the double arrow 21 (see FIG.

Die Rollensegmenthälften 19 bzw. 20 sind der Kontur der Bundbildevorrichtung 2 angepaßt und umfassen diese beidseitig teilumfänglich bis etwa zur Mittenebene, wie in Fig. 4 dargestellt. In Fig. 2 ist zu erkennen, daß die einander gegenüberliegenden Stummelrollen 18a bis 18d in Transportrichtung 7 und somit zum Abwurfbereich der Bundbildevorrichtung 2 hin stufenweise kürzer werden, d.h. die ersten Stummelrollen 18a sind länger als die in Transportrichtung 7 folgenden Stummelrollen, wobei die letzten Stummelrollen 18d am kürzesten sind.The roller segment halves 19 and 20 are adapted to the contour of the collar forming device 2 and include these on both sides partially circumferentially to about the center plane, as shown in Fig. 4. In Fig. 2 it can be seen that the opposing stub rolls 18a to 18d in the transport direction 7 and thus to the discharge area of the collar forming device 2 towards gradually become shorter, ie the first stub rolls 18a are longer than the following in the transport direction 7 stub rolls, the last stub rolls 18d are the shortest.
