Description
Es sind Vorrichtungen zur Teilung eines größeren Profils beim Walzen von Profilstählen durch eine Schneidevorrichtung bekannt.There are devices for dividing a larger profile when rolling of profile steels known by a cutting device.
Diese haben den Nachteil, daß die Schneidewerkzeuge den Steg der Profile stärker längere .als die Flansche. Dadurch entsteht ein Auseinanderlaufen der beiden Profilhälften.These have the disadvantage that the cutting tools cut the web of the profiles longer than the flanges. This creates a divergence between the two Profile halves.
Man hat deshalb bereits versucht, diesen Nachteil zu vermeiden, indem man: eine zusätzliche Vorrichtung zum nachträglichen Richten der Profilhälften benutzt hat.Attempts have therefore already been made to avoid this disadvantage by man: an additional device is used for the subsequent straightening of the profile halves Has.
Durch diese Maßnahme waren jedoch. verhältn.;smäßig hohe Kosten bedingt. Auch nahm die zusätzliche Vorrichtung verhältnismäßig viel Raum in Anspruch.By this measure, however, were. relative; moderately high costs. The additional device also took up a relatively large amount of space.
Demgegenüber wird gemäß der Erfindung für die Schneidevorrichtung mit Messerrollen eine Steuerung vorgesehen. die den Schnitt durch das Profil erst dicht hinter dessen Kopfende beginnen und ebenso dicht vor dessen Endzunge enden läßt.In contrast, according to the invention for the cutting device a control is provided with knife rollers. the cut through the profile only begin just behind its head end and end just as close in front of its end tongue leaves.
Eine solche Steuervorrichtung läßt sich in einfacher und deshalb auch billiger Weise herstellen und an der an sich vorhandenen Anlage anordnen. Sie wirkt zuverlässig und kann automatisch durch einen auf die Dehnung eines Elementes des Poliergerüstes, beispielsweise des Ständers, ansprechenden Dehnungsmesser beeinflußt werden.Such a control device can be in a simpler and therefore also cheaper way to manufacture and arrange on the existing system. She works reliable and can be automatically activated by an on the expansion of an element of the Polishing frame, for example the stand, affecting the appealing strain gauge will.
Die Endstücke des auf diese Weise geteilten Profils verhindern mit Sicherheit ein Auseinanderlaufen der beiden Profilhälften, und da sie an sich schon. vom Profil abgeschnitten und in der, Schrott geworfen werden, bedeutet ihr nachträgliches Abschneiden bei Anwendung der Erfindung keinen zusätzlichen Verlust.The end pieces of the profile divided in this way prevent with Security a divergence of the two profile halves, and since they are already. cut off from the profile and in the, scrap is thrown, means her afterwards Truncation using the invention does not cause any additional loss.
Es ist zweckmäßig, daß bei Anwendung der Erfindung die Polierwalzen eine Form aufweisen, die den. Trennschnitt der Schneidevorrichtung vorbereitet.It is desirable that when using the invention, the polishing rollers have a shape that corresponds to the. Separating cut of the cutting device prepared.
Wird außerdem das ursprünglich ausgewalzte Profil durch den Trennschrnitt nicht vollkommen durchgeschnitten, sondern beispielsweise nur tief eingekerbt. was bei besonders dickem Walzmaterial angebracht erscheinen kann, so wird die Möglichkeit weiter erhöht, einen geraden Lauf des Walzgutes zu gewährleisten. Die völlige Trennung kann in einfacher Weise anschließend im kalten Zustand durch Brechen, z. B. in einer Rollenrichtma,schine, erfolgen. Die Bruchkanten sind nur gering und lassen sich ohne Schwierigkeiten, beispielsweise in einer automatischen Schleifmaschine, beseitigen.In addition, the originally rolled-out profile becomes the result of the separating cut not completely cut through, but only deeply notched, for example. What may appear appropriate in the case of particularly thick rolled material, the possibility becomes further increased to ensure a straight run of the rolling stock. The complete separation can then in a simple manner in the cold state by breaking, z. B. in a Role straightening machine. The break lines are only slight and can be without difficulty, for example in an automatic grinding machine.
In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung dargestellt.In the drawing, an exemplary embodiment is shown in FIG Invention shown.
Fig. i zeigt die neue Vorrichtung in der Seiten, ansicht, Fig. 2, 3 und' 4 zeigen verschiedene Ausführungsformen eines Schneidewerkzeuges.Fig. I shows the new device in the side view, Fig. 2, Figures 3 and 4 show different embodiments of a cutting tool.
Danach. ist un-nittelbar hinter dem Poliergerät i, das die Oberwalze 2 und die Unterwalze 3 trägt, eine Schneidevorrichtung angeordnet, die im wesentlichen aus eurer oberen Messerrolle 4 undaus einer unteren Messerrolle 5 besteht. Beide Rallen sind lieb- und senkbar in einem Gestell h gelabert, und' ihr gegenseitiger Abstand' kann durch einen Dehnungsmesser 7 gesteuert werden, der unter dem Einfluß eines Elementes des Poliergerüstes, z. B.. seines Ständers, steht.Thereafter. is immediately behind the polishing device i, which is the top roller 2 and the lower roller 3 carries, a cutting device is arranged, which essentially consists of your upper knife roll 4 and a lower knife roll 5. Both Rails are lovable and lowerable in a frame, and they are mutual Distance 'can be controlled by a strain gauge 7, which is under the influence an element of the polishing framework, e.g. B .. of his stand, stands.
Ein I-Träger S, der nach dem üblichen Durchgang durch eine Walzenstraße schließlich das Poliergerüst t in Richtung des Pfeiles q verläßt, gelangt nunmehr zwischen die Müsserrollert a, 5. Diese werden durch den Dehnungsmesser 7 derart gesteuert, daß sie erst nach Durchgang des Kopfendes des I-Trägers 8 in ihre Schnittstellung gelangen, aus dieser jedoch wieder abgeschoben werden. kurz bevor si;: die Endzung,- dieses Trägers erreichen.An I-beam S, which after the usual passage through a rolling mill finally leaving the polishing stand t in the direction of arrow q, now arrives between the Müsserrollert a, 5. These are determined by the strain gauge 7 in such a way controlled that they only after passage of the head end of the I-beam 8 in their cutting position get, but are deported from this again. shortly before si;: the ending, reach this vehicle.
Durch diese Steuerung wird außerdem verhindert. daß die Messerrollen a, 5 beim Austritt des Walzstabes hart aufeinanderschlagen können. Sie werden deshalb besonders geschont.This control also prevents. that the knife rollers a, 5 can hit each other hard at the exit of the roll bar. You will therefore especially spared.
Fig.2 zeigt die Möglichkeit. zwei Messerrollen io, i i übereinander zu verwenden, deren Schneiden im Querschnitt V-förmig ausgebildet sind, so daß insgesamt ein X-förmiger Schnitt entsteht. Man kann aber auch eine derartige iVIesserrolle i2 mit einer gewöhnlichen Druckrolle 13 zusammenarbeiten lassen, so d-aß im wesentlichen eire V-förmiger Schnitt erzeugt wird. Gemäß Fig.4 sind scließlich die Schneidekanten der Messerrollen 1.4, 15 ausgerundet, so d'aß sie den Stegkanten der durch sie erzeugten Stäbe :Abrundungen verleihen.Fig.2 shows the possibility. To use two knife rollers io, ii one above the other, the cutting edges of which are V-shaped in cross-section, so that overall an X-shaped cut is produced. However, one can also have such an iVIesserrolle i2 work together with an ordinary pressure roller 13 , so that essentially a V-shaped cut is produced. Finally, according to FIG. 4, the cutting edges of the knife rollers 1.4, 15 are rounded so that they give the web edges of the rods produced by them rounding.
