Description
Aufrollmaschine für Eisen- und Metallbänder für den Wickelbund bei Walzwerken Eisen- und Metallbänder werden vielfach nach dem Vorwalzen in Rollenform gebracht. Hierbei wird das Band durch Biegewalzen geleitet, die das noch verhältnismäßig steife Band derart durchbiegen, daß es das Bestreben hat, sich aufzurollen. Zur Erleichterung der Rollenbildung werden oberhalb der Biegewalzen entsprechend gebogene Führungsplatten und zum Teil angetriebene Stützrollen vorgesehen. Da-die sich bildende Bandrolle an der Führungsplatte gleitet, sind hier zur Verminderung der Reibung auch schon lose mitlaufende Rollen eingelegt worden. Trotz dieser Verminderung der Reibung kommt es vor, daß die Steifheit- des aus den Biegewalzen austretenden Bandes nicht mehr genügt, um die noch verbleibende Reibung zu überwinden und die schwerer gewordene Bandrolle weiterzudrehen. Bei den bekannten Aufrollmaschinen ist das erreichbare Gewicht und die erreichbare Bandlänge eines gewickelten Bundes von der Steifheit des Bandes abhängig, die an sich wieder vön der Banddicke und der Temperatur beeinflußt wird. Bei Änderung einer oder mehrerer dieser Grundlagen treten Störungen ein, die in bezug auf Ausbringen und Qualität recht ungünstig wirken.Rewinder for iron and metal strips for the wrapped collar Rolling mills Iron and metal strips are often rolled into rolls after roughing brought. Here, the strip is passed through bending rollers, which are still proportionate bend the stiff band in such a way that it tends to roll up. To the To facilitate roll formation, they are bent accordingly above the bending rollers Guide plates and partly driven support rollers are provided. Da-the forming Tape roll slides on the guide plate are here to reduce friction loosely running rollers have also been inserted. Despite this reduction in Friction it happens that the stiffness of the band emerging from the bending rollers is no longer enough to overcome the remaining friction and the heavier one to continue turning the reel that has become. This is achievable with the known reeling machines Weight and the achievable tape length of a wound bundle on the stiffness of the strip, which in turn is influenced by the strip thickness and the temperature will. If one or more of these fundamentals are changed, disturbances occur that appear quite unfavorable in terms of yield and quality.
Zweck der Erfindung ist, diese Mängel zu beheben.The purpose of the invention is to remedy these deficiencies.
Bei einer Aufrollmaschine für Eisen- und Metallbänder mittels Biegerollen und Stützrollen für den Wickelbund bei Bandwalzwer-. ken wird erfindungsgemäß die Anordnung so getroffen däß zur vollständigen Führung des Wickelbundes weitere angetriebene Rollen vorgesehen sind, die außerdem das Aufrollen des Bundes unterstützen. Hierdurch ergibt sich die fortschrittliche Wirkung, daß das Gewicht und die Bandlänge eines gewickelten Bundes nicht mehr von der Steifheit des Bandes abhängig ist. Die mit größerer Umfangsgeschwindigkeit als die Bandgeschwindigkeit arbeitenden angetriebenen Rollen üben eine Zug- und Druckwirkung auf das Band aus, so daß längere und dünnere Bänder, auch in warmem Zustand, wo die Steifheit des Metalls nicht sehr groß ist, aufgerollt werden können. . Da erfahrungsgemäß beim Vorwalzen schwerer Blöcke zu dünnen langen- Bändern die Selbstkosten sinken, so wird durch die Verwendung der neuen Aufrollmaschine auch ein wirtschaftlicher Erfolg erreicht.With a rewinder for iron and metal strips by means of bending rollers and support rollers for the winding collar in strip rolling mills. ken is according to the invention the Arrangement made so that further driven ones for the complete guidance of the winding collar Roles are provided that also support the rolling up of the federal government. Through this results in the advanced effect that the weight and the length of a tape wound covenant no longer depends on the stiffness of the belt. With greater peripheral speed than the belt speed working driven Rollers exert a tensile and compressive effect on the belt, so that longer and thinner ones Belts, even when they are warm, where the stiffness of the metal is not very great, can be rolled up. . Experience has shown that when roughing heavy blocks, too thin long-ribbons the cost will decrease, so will through the use of the new rewinder also achieved an economic success.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.
Abb. i veranschaulicht einen Aufriß der Maschine, in Richtung der Achsen der Biegewalzen gesehen; Abb.2 zeigt den Seitenriß, senkrecht auf die Biegewalze gesehen.Fig. I illustrates an elevation of the machine, looking in the direction of Axes of the bending rolls seen; Fig.2 shows the side elevation, perpendicular to the bending roller seen.
Mit i, 2 und 3 sind die Biegewalzen bezeichnet und mit 4. das Band bzw. die sich bildende Bandrolle, mit $, 6, 7 und 8 die Rollen, die oberhalb und seitlich der Biegewalzen angeordnet sind. Sowohl die Biegewalzen i, 2, 3 als auch die Rollen 5, 6, 7 und 8 werden von dem Motor 9 unter Zwischenschaltung des Räderkastens io und von Gelenkspindeln i i und 12 angetrieben. Die Drehrichtung der Biegewalzen und der Rollen sowie die Bewegungsrichtung des Bandes sind durch Pfeile in der Zeichnung gekennzeichnet. Die Rollen 5; 6, 7 und 8 sind noch in Schlitzen verstellbar, um sie der Größe der sich bildenden Bandrolle anzupassen.The bending rollers are denoted by i, 2 and 3 and the band is denoted by 4. or the forming tape roll, with $, 6, 7 and 8 the roles above and are arranged laterally of the bending rollers. Both the bending rollers i, 2, 3 and the rollers 5, 6, 7 and 8 are driven by the motor 9 with the interposition of the gear case io and driven by articulated spindles i i and 12. The direction of rotation of the bending rollers and the rollers as well as the direction of movement of the belt are indicated by arrows in the drawing marked. The roles 5; 6, 7 and 8 are still adjustable in slots to adapt them to the size of the roll of tape being formed.
Das aufzurollende Band wird in Pfeilrichtung in die Biegewalzen i, 2 und 3 eingeführt, die ihm das Bestreben geben, sich in Pfeilrichtung weiterzubewegen und sich auf den. angetriebenen Rollen 5, 6, 7 und 8 in Rollenform zu bilden. Dadurch, daß die Rollen 5, 6, 7 und 8 eine etwas größere Umfangsgeschwindigkeit haben als die Biegewalzen und damit auch die sich bildende und drehende Bandrolle 4, so unterstützen die Rollen 5, 6, 7 und 8 das Drehen der Bandrolle.The tape to be rolled up is fed into the bending rollers i in the direction of the arrow, 2 and 3 introduced, which give him the desire to move on in the direction of the arrow and focus on the. driven rollers 5, 6, 7 and 8 in roll form. Through this, that the rollers 5, 6, 7 and 8 have a slightly greater peripheral speed than support the bending rollers and thus also the forming and rotating tape roll 4 rollers 5, 6, 7 and 8 rotate the roll of tape.
