The guide has a guide roller pair which are mutually juxtaposed and journaled on free ends of pivot arms of double arm levers. The lever journals are connected with a support body between the finish mill rolls of the rolling line and which has a centering funnel for the rolled wire or rod between the double arm levers. The whereby the pivotal displacements of the pivot arms are settable and spring adjustable about the lever journals. The roller guide is improved in that the pivot arms have setting elements pressed against the support body and in that an adjustable-pressure pneumatic spring connected with the support body and bearing upon the pivot arm extending away from the guide roller or is connected with this pivot arm.

Description

Die Erfindung betrifft eine Rollenführumg für die Drahtführung zwischen den Fertiggerüsten von Drahtwaizstraßen, bestehend aus einem Führungsroltenpaar, dessen Führungsrollen einander gegenüberliegend, an den freien Enden der Schwenkarme von doppelarmigen Hebeln lagern, deren Hebellager mit einem zwischen den Fertiggerüsten der Walzstraße angeordneten Tragkörper verbunden sind, der zwischen den doppelarmigen Hebeln einen Zentriertrichter für den Walzdraht aufnimmt, wobei die Schwenkwege der Schwenkarme um das Hebeilager federverstell- und festlegbar sind, mit an den Schwenkarmen angeordnet, gegen den Tragkörper abgestützten Stellelementen (siehe z.B. JP-A-06047424).The invention relates to a Rollenführumg for the wire guide between the finishing stands from Drahtwaizstraßen, consisting of a leading role pair, whose guide rollers are opposite each other, at the free ends of the Store swivel arms from double-armed levers whose lever bearings are fitted with a lever connected between the finishing stands of the rolling mill arranged supporting body are the, between the two-armed levers a centering funnel for receiving the wire rod, wherein the pivoting paths of the pivot arms about the lifting bearing Federverstell- and can be fixed, with arranged on the pivot arms, actuators supported against the support body (see, for example, JP-A-06047424).

Führungsrollen dieser Art dienen dazu, den Walzdraht zuverlässig in das, den Führungsrollen nachgeordnete Kaliber des Walzgerüstes einzuführen. Die Führungsrollen werden dabei auf die Kalibermitte ausgerichtet, so nahe wie möglich vor den Walzen positioniert, weil, abgesehen von den hohen Geschwindigkeiten, mit denen der Draht die Fertiggerüste moderner Drahtstraßen passiert, in diesem Abschnitt der Drahtwalzstraße den engen kalibertoleranzen Rechnung zu tragen ist. Die Führungsrollen müssen deshalb den in diesen Formabschnitt noch ovalförmigen Drahtquerschnitt stets spielfrei einfassen, um einem Kippen in dem Kaliber vorzubeugen. Dies wurde durch entsprechende Einstellung der Schwenkwege der Schwenkarme der, die Führungsrollen tragenden, meist von Blattfedern abgestützten Doppelhebeln erreicht.Guide rollers of this type serve the wire rod reliably in the Introduce guide rollers downstream caliber of the rolling mill. The leadership roles are aligned with the caliber center as close as possible positioned in front of the rollers because, apart from the high speeds, with which the wire passes the finished scaffolding of modern wire-lines, in this Section of the wire rolling mill to take into account the tight calibration tolerances is. The guide rollers must therefore still oval in this form of section Always grasp the wire cross-section to avoid tilting in the caliber submissions. This was done by adjusting the pivoting the swing arms of the, supporting the guide rollers, usually supported by leaf springs Double levers reached.

Der wesentliche Nachteil dieser Rollenführung ergibt sich daraus, dass die auf eine bestimmte durchschnittliche Querschnittsgröße abgestimmte Einstellung der Führungsrollen infolge der unvermeidlichen Querschnittsänderungen des herangeführten Walzdrahtes ständig zu erhöhten Druckbelastungen der Führungsrollen und des Walzdrahtes führt, wenn der Drahtquerschnitt die eingestellten Maße überschreitet. In diesen Fällen wirken die Führungsroilen häufig als zusätzliche Walzelemente. Hierdurch werden nicht nur die Toleranzen des Drahtquerschnitts verschlechtert, sondern auch die Lager der Führungsrollen und diese selbst über das übliche Maß hinaus belastet.The main disadvantage of this role leadership results from the fact that on a certain average cross sectional size tuned attitude of the Guide rollers due to the inevitable cross-sectional changes of the brought up Wire rod constantly to increased pressure loads of the guide rollers and the wire rod leads when the wire cross section the set dimensions exceeds. In these cases, the guide ropes often act as additional Rolling elements. As a result, not only the tolerances of the wire cross section but also the bearings of leadership roles and these themselves over burdened the usual extent.

Andererseits führen, das eingestellte Maß unterschreitende Querschnittsgrößen des durchlaufenden Walzdrahtes wegen der dadurch bedingten lockereren Führung des Walzdrahtes häufig dazu, dass der Draht dazu neigt, im Führungskaliber zu kippen; dies ist insb. bei ovalen Querschnitten mit der Folge der Fall, dass sich auch hier die Toleranzen verschlechtern. In Extremfällen kann es dabei zu Überwalzungen kommen.On the other hand lead the set dimension below cross-sectional sizes the continuous wire rod because of the consequent looser leadership of the wire rod often causes the wire to tend to stick in the guide caliber to tilt; this is esp. In oval cross-sections with the result of the case that even here, the tolerances deteriorate. In extreme cases, this can lead to Überwalzungen come.

Diese Schwierigkeiten erhöhen sich beim Maßwalzen nach dem sogenannten "Free Size Rolling"-System, da sich hier die Fertigquerschnitte des Walzdrahtes in einem sehr engen Bereich halten und dabei gezielt unterschiedliche Querschnitte in ein und demselben Walzkaliber gewalzt werden.These difficulties increase in the sizing after the so-called "Free Size Rolling" system, as here the finished cross sections of the wire rod in keep a very narrow range and thereby selectively different cross sections rolled in one and the same rolling caliber.

Der Erfindung liegt die Aufgabe zugrunde, die bekannten Rollenführungen so zu verbessern, dass sich die Drahtführung den ständigen Querschnittsänderungen selbsttätig anpaßt.The invention is based on the object, the known roller guides so Improve that the wire guide the constant cross-sectional changes automatically adapts.

Diese Aufgabe wird durch eine mit dem Tragkörper verbundene gegen einen, der Führungsrolle abgewandten Schwenkarme abgestützte bzw. mit diesem Schwenkarm verbundene, gegen den Tragkörper abgestützte, während des Durchlaufs des Walzgutes auf einen konstanten Luftdruck einstellbare Pneumatikfeder gelöst.This object is achieved by a connected to the support body against a, the Guide role facing away swivel arms supported or with this Swivel arm connected, supported against the support body, during the Passage of the rolling stock to a constant air pressure adjustable pneumatic spring solved.

Es ist auch möglich, wie die Erfindung weiter vorsieht, beide der Führungsrolle abgewandten Schwenkarme mit je einer, gegen den Tragkörper abgestützten pneumatischen Feder zu versehen: It is also possible, as the invention further provides, both of the guiding role facing away pivot arms with one, supported against the support body to provide pneumatic spring:

Die pneumatische Feder, die bei einer Stellverschiebung in einem festlegbaren Bereich stets mit konstanter Kraft dieser Verschiebung entgegenwirkt, führt dazu, dass eine damit ausgerüstete Rollenführung unterschiedliche Drahtquerschnitte in das Kaliber einführen kann und dabei sowohl der Walzdraht als auch die Führungsrollen unabhängig von der Größe der geführten Querschnitte stets mit gleichbleibenden Drücken beaufschlagt werden. Der Walzdraht wird durch diese adaptive Rollenführung unabhängig von den Querschnittsschwankungen spielfrei mit konstanter Kraft geführt und es bedarf in bestimmten Drahtquerschnittsbereichen keiner jedesmaligen Neueinstellung, mit der Folge von Zeiteinsparungen beim Walzbetrieb und entsprechenden Senkungen der Betriebskosten. Neben den erzielten besseren Toleranzen erhöhten sich auch die Standzeiten der Führungsrollen und ihrer Lager und führen zu weiteren Kostensenkungen.The pneumatic spring, which at a Stellverschiebung in a definable Always counteracts this shift with constant force, that a roller guide equipped therewith has different wire cross sections in can introduce the caliber and thereby both the wire rod and the guide rollers regardless of the size of the guided cross sections always with constant pressures are applied. The wire rod is going through this Adaptive roller guide free from play, regardless of the variations in cross section guided with constant force and it requires in certain wire cross-sectional areas no new hiring, with the result of time savings during rolling operation and corresponding reductions in operating costs. In addition to the Achieved better tolerances also increased the service life of the guide rollers and their bearings and lead to further cost reductions.

Wie aus den Fig. 1 und 2 zu ersehen, besteht die Rollenführung, die unmittelbar vor dem durch die beiden Waben WZ1, WZ2 gebildeten Walzspalt WS angeordnet ist, aus einem Tragkörper TK, der auf nicht dargestellte Weise mit dem Walzgerüst verbunden ist, und der es erlaubt, die Rollenführung auf diesen Walzspalt WS auszurichten. An dem Tragkörper ist beiderseits eines, von diesem getragenen Zentriertrichters ZT für den in Richtung des Pfeils in diesen einführbaren. nicht dargestellten Walzdraht, je ein Doppelhebel DH in einem Hebellager HL gelagert, angeordnet. Die den Walzen WL1 und WL2 zugeordneten Schwenkarme SA1a, SA2a der Doppelhebel DH tragen die beiden Führungsrollen FR1 und FR2 und, ebenso wie die diesen Führungsrollen abgewandten Schwenkarme SA1b und SA2b jeweils gegen den Tragkörper TK abgestützte Stellelemente SEa und SEb.As can be seen from Figs. 1 and 2, there is the roller guide, the immediate arranged in front of the roll gap WS formed by the two honeycombs WZ1, WZ2 is, from a support body TK, in a manner not shown with the roll stand is connected, and which allows the roller guide on this nip Align WS. On the support body is on both sides of one, carried by this Zentreltrichters ZT for the direction of the arrow in this insertable. Not shown wire rod, each a double lever DH stored in a lever bearing HL, arranged. The swivel arms SA1a assigned to the rollers WL1 and WL2, SA2a of the double lever DH carry the two guide rollers FR1 and FR2 and, as well as the guide rollers facing away from these pivot arms SA1b and SA2b each against the support body TK supported actuators SEa and SEb.

An den Tragkörper TK ist weiter (vgl. Fig. 3), oberhalb des Zentriertrichters ZT eine Pneumatikfeder PF mit einem Stellglied SG angeordnet, das hier den der Führungsrolle FR2 abgewandten Schwenkarm SA2b beaufschlagt. Die Pneumatikfeder PF ist in eine entsprechende Aufnahmeöffnung im Tragkörper TK einsteckbar und mit einer Klemmvorrichtung KL gesichert.To the support body TK is further (see Fig. 3), above the Zentriertrichters ZT a Pneumatic spring PF arranged with an actuator SG, here the leadership FR2 facing away pivot arm SA2b acted upon. The pneumatic spring PF can be inserted into a corresponding receiving opening in the supporting body TK and secured with a clamping device KL.

Bei der Rollenführung nach den Fig. 4 und 5, deren Ausbildung mit Ausnahme der Anordnung der Pneumatikfeder PF der Ausbildung nach den Fig. 1 bis 3 entspricht, ist diese Pneumatikfeder PF nicht, wie dort, mit dem Tragkörper TK verbunden, sondern auf dem der Führungsrolle FR2 abgewandten Schwenkarm SA2b. Das Stellglied SG der Pneumatikfeder PF stützt sich hier gegen den Tragkörper TK ab.In the roller guide according to FIGS. 4 and 5, whose training with the exception of Arrangement of the pneumatic spring PF corresponds to the embodiment according to FIGS. 1 to 3, this pneumatic spring PF is not, as there, connected to the support body TK, but on the guide roller FR2 facing away from the swivel arm SA2B. The actuator SG of the pneumatic spring PF is supported here against the Carrying body TK from.

Der Walzdraht, z.B. mit Ovalquerschnitt, wird von dem Zentriertrichter ZT dem von den Führungsrollen FR1 und FR2 gebildeten Führungsspalt zugeführt. Dieser Führungsspalt wird mit Hilfe der Stellelemente SEa, SEb eingestellt und zwar so, dass die Spaltweite um einen off-set kleiner ist als der Soll-Querschnitt des Walzdrahts. Im Anschluß an diese Einstellung wird die Pneumatikfeder PF in die Aufnahmeöffnung des Tragkörpers TK eingeschoben und mit der Klemmvorrichtung KL gesichert. Das Profil des in den Führungsspalt einlaufenden Walzdrahts öffnet dann diesen Spalt entgegen dem Druck der Pneumatikfeder PF um einen, den aktuellen Querschnitt entsprechenden Wert. Die Pneumatikfeder PF bewirkt dabei, dass die Führungsrollen FR1, FR2 mit der in der in dieser Pneumatikfeder voreingestellten Federkraft beaufschlagt werden. Diese Federkraft wird dabei so bemessen, dass die Führungsrollen FR1, FR2 den Walzdraht, unabhängig von durchlaufenden Walzdrahtabschnitten mit abweichendem Durchmesser stets mit gleichbleibendem Druck beaufschlagen. Die Federkraft der Pneumatikfeder PF wird dabei so bemessen, dass der Walzdraht von den Führungsrollen FR1, FR2 sicher geführt, aber nicht walzbeaufschlagt wird. The wire rod, e.g. with oval cross-section, is from the centering ZT the of fed to the guide rollers FR1 and FR2 formed guide gap. This Guide gap is set by means of the actuators SEa, SEb and that way, that the gap width is smaller by an off-set than the desired cross-section of the wire rod. Following this adjustment, the pneumatic spring PF is in the receiving opening of the support body TK inserted and with the clamping device KL secured. The profile of the incoming wire rod in the guide gap opens then this gap against the pressure of the pneumatic spring PF to one, the current cross-section corresponding value. The pneumatic spring PF thereby causes that the guide rollers FR1, FR2 with the preset in this pneumatic spring Spring force to be applied. This spring force is thereby dimensioned that the guide rollers FR1, FR2 the wire rod, regardless of passing Wire rod sections with different diameter always with the same Apply pressure. The spring force of the pneumatic spring PF is there so dimensioned that the wire rod from the guide rollers FR1, FR2 safe led, but not rolled.
