Abstract

Round rolled bars deposited side by side on a transport roller conveyor in cooling-bed position are automatically threaded into the cross-cutting shears, by the fact that specifically arranged and formed comb-like profile strips which can be raised and lowered are provided underneath and across the rolled bars. <IMAGE>

Description

Die Neuerung betrifft eine Einrichtung zum Ausrichten von in Kühlbettlage auf einem Transportrollgang vor einer Querteilschere in entsprechender An­zahl nebeneinander abgelegter runder Walzgutstäbe auf die Teilung des pro­filierten Scherenmessers.The innovation relates to a device for aligning in a cooling bed position on a transport roller table in front of a cross-cut shear in a corresponding number of round rolled rods placed next to one another to the division of the profiled shear knife.

Kleinkalibrige und mittlere Walzstäbe werden üblicherweise nach Verlassen des Kühlbettes auf Kaltscheren in Handelslängen unterteilt. Hierbei ist es üblich, den Scheren eine Vielzahl von Walzstäben nebeneinander zuzuleiten, die gleichzeitig geschnitten werden. Je nach Art des zu schneidenden Walz­gutes werden Scherenmesser verwendet, deren Schneiden dem Profil der zu schneidenden Walzgutstäbe angepaßt sind. Dazu ist es erforderlich, die Stäbe in die von den Profilausnehmungen in den Messern gebildeten Öffnungen einzuführen, um sodann die Schere in Tätigkeit zu setzen.Small-caliber and medium-sized bars are usually divided into commercial lengths after leaving the cooling bed on cold shears. It is customary here to feed the shears a large number of roll bars next to one another, which are cut at the same time. Depending on the type of rolling stock to be cut, scissors knives are used, the cutting of which is adapted to the profile of the rolling stock to be cut. For this purpose, it is necessary to insert the rods into the openings formed by the profile recesses in the knives in order to then start the scissors.

Bekannte Kaltscheren sind am Ende eines Rollganges angeordnet, auf den die Walzgutstäbe vom Kühlbett kommend übergeben werden. Da die Stäbe in Ab­ständen auf den Rollgang gelegt werden, die den Teilungen des Kühlbettes entsprechen, müssen die Stäbe vor der Schere ausgerichtet werden, wenn die Teilung der Schere nicht der des Kühlbettes entspricht. Bisher wurde diese Ausrichtung von Hand vorgenommen, was sehr zeitaufwendig war und den mög­lichen Scherendurchsatz verminderte.Known cold scissors are arranged at the end of a roller table to which the rolled stock is transferred from the cooling bed. Since the bars are placed on the roller table at intervals that correspond to the divisions of the cooling bed, the bars must be aligned in front of the scissors if the division of the scissors does not correspond to that of the cooling bed. Until now, this alignment was done by hand, which was very time-consuming and reduced the possible shear throughput.

Aufgabe der vorliegenden Neuerung ist es, eine Einrichtung zum Ausrichten von runden Walzgutstäben auf die Teilung der Querteilschere zu schaffen, mit der ein automatischen Einfädeln in die profilierten Schermesser möglich ist.The object of the present innovation is to create a device for aligning round rolling stock on the division of the cross-cut shear, with which an automatic threading into the profiled shear blades is possible.

Neuerungsgemäß werden die im Schutzanspruch beschriebenen Merkmale vorge­sehen, die ein Automatisieren des Vorganges möglich machen und durch Ent­fallen des manuellen Einlegens der Walzgutstäbe den Scherendurchsatz erhö­hen.According to the invention, the features described in the protection claim are provided which make it possible to automate the process and increase the shear throughput by eliminating the manual insertion of the rolled stock.

Anhand der Zeichnung wird die Neuerung nachfolgend erläutert. Es zeigt:

Figur 1 ist mit 1 eine der Rollgangsrollen bezeichnet, auf der die bei 2 angedeuteten Walzgutstäbe abgelegt sind. Unterhalb der Rollgangsrole 1 ist die Profilleiste 3 erkennbar, die mit einer Vielzahl von Ausnehmungen 4 versehen ist, deren Abstand und Teilung der Teilung des nicht dargestellten profilierten Scherenmessers entspricht. Die Profilleiste 3 ist in Pfeilrichtung 5 heb- und senkbar. In Walzgutrichtung sind mehrere, mindestens 2 dieser Profilleisten im Abstand zueinander angeordnet, um eine ordnungsgemäße Auflage der Profilstäbe 2 zu gewährleisten.FIG. 1 denotes 1 of the roller table rollers on which the rolled stock bars indicated at 2 are placed. Below the roller table roller 1, the profile strip 3 can be seen, which is provided with a multiplicity of recesses 4, the spacing and division of which corresponds to the division of the profiled scissor knife, not shown. The profile bar 3 can be raised and lowered in the direction of the arrow 5. In the direction of the rolling stock there are several at least 2 of these profile strips are arranged at a distance from one another in order to ensure a proper support of the profile bars 2.

Ebenfalls in Figur 1 ist links davon eine der Verteileinrichtungen 6 er­kennbar, die jeweils aus einem ersten Träger 7 und aus einem zweiten Träger 8 besteht. Beide Träger sind in horizontaler Richtung frei auskragend ge­staltet, wobei der zweite Träger 8 gegenüber dem ersten Träger 7 in verti­kaler Richtung, wie bei 9 angedeutet, heb- und senkbar ist. Am freien Ende des ersten Trägers 7 ist eine nach unten ragende Mitnehmernase 10 ausgebildet, deren Funktion nachfolgend noch beschrieben werden wird. Der zweite Träger 8 ist in Axialrichtung gegenüber dem ersten Träger 7 ver­stellbar.Likewise in FIG. 1, one of the distribution devices 6 can be seen to the left of it, each of which consists of a first carrier 7 and a second carrier 8. Both carriers are designed to be freely cantilevered in the horizontal direction, the second carrier 8 being able to be raised and lowered in the vertical direction relative to the first carrier 7, as indicated at 9. At the free end of the first carrier 7, a downwardly projecting driver nose 10 is formed, the function of which will be described below. The second carrier 8 is adjustable in the axial direction relative to the first carrier 7.

In Figur 2 ist die Verteileinrichtung in den Bereich des Rollganges einge­fahren dargestellt, wobei der erste Träger 7 die Walzgutstäbe 2 überkragt und der zweite Träger 8 die Walzgutstäbe 2 untergreift. In dieser Stellung beginnt die eigentliche Verteilfunktion der neuerungsgemäßen Einrichtung, deren Funktionsweise nachfolgend beschrieben wird:In FIG. 2, the distribution device is shown retracted into the area of the roller table, the first carrier 7 projecting over the rolling stock bars 2 and the second carrier 8 engaging under the rolling stock bars 2. In this position, the actual distribution function of the new device begins, the operation of which is described below:

Durch Einfahren der Verschiebeeinrichtung 6 in den Rollgangsbereich vor der Kaltschere werden, wie in Figur 2 dargestellt, zunächst die Walzgutstäbe 2 eng aneinandergeschoben. Die Anzahl der Walzgutstäbe 2 entspricht der An­zahl der Profilausnehmungen in dem nicht dargestellten Scherenmesser sowie der wirksamen Länge der Träger 7 und 8 der Verteileinrichtung. Wie in Figur 3 dargestellt, wird nach dem Aneinanderlegen der Walzgutstäbe 2 zunächst der zweite Träger 8 angehoben, wodurch die Walzgutstäbe 2 vom Rollgang 1 abgehoben werden. Gleichzeitig wird die Profilleiste 3 ebenfalls angeho­ ben, und zwar in eine Ebene oberhalb des Rollganges 1 jedoch nur so weit, daß in seitlicher Überdeckung die Aufnahmen 4 der Profilleiste 3 durch den zweiten Träger 8 verschlossen sind, wie dies in den Figuren 2 und 3 er­kennbar ist.By moving the displacement device 6 into the roller table area in front of the cold shears, as shown in FIG. 2, the rolled stock bars 2 are first pushed close together. The number of rolled bars 2 corresponds to the number of profile recesses in the scissor knife, not shown, and the effective length of the beams 7 and 8 of the distribution device. As shown in FIG. 3, after the rolling stock 2 has been placed against one another, the second carrier 8 is first raised, whereby the rolling stock 2 is lifted off the roller table 1. At the same time the profile bar 3 is also raised ben, in a plane above the roller table 1 but only so far that the receptacles 4 of the profile strip 3 are closed by the second carrier 8 in a lateral overlap, as can be seen in Figures 2 and 3.

In der hochgefahrenen Stellung verbleibt zwischen dem ersten Träger 7 und dem die Aufnahmen 4 der Profilleisten 3 verschließenden unteren Träger 8 ein lichter Zwischenraum, der etwas größer als der Durchmesser der Walz­gutstäbe ist. Die zwischen den Aufnahmen 4 verbleibenden Zähne der Profil­leiste 3 müssen die Kontur des unteren Träges 8 geringfügig überragen.In the raised position, a clear space remains between the first support 7 and the lower support 8, which closes the receptacles 4 of the profiled strips 3, and is slightly larger than the diameter of the rolled stock bars. The teeth of the profile strip 3 remaining between the receptacles 4 must slightly protrude beyond the contour of the lower support 8.

In der in Figur 3 dargestellten Stellung beginnt der Arbeitszyklus des Verteilens. Durch seitliches - in der Zeichnung nach links - Verschieben sowohl des ersten als auch des zweiten Trägers 7 und 8 werden durch den zweiten Träger 8 nacheinander von rechts nach links die Aufnahmen 4 in den Profilleisten freigegeben. Der zweite Träger 8 ist gegenüber dem ersten Träger 7 in Axialrichtung so eingestellt, daß zwischen der Mitnehmernase 10 und dem Ende 11 des zweiten Trägers 8 ein nach unten offener Durchlaß ver­bleibt, der dem Durchmesser eines der zu verteilenden Walzgutstäbe 2 ent­spricht (Figur 3a).In the position shown in Figure 3, the distribution cycle begins. By moving laterally - in the drawing to the left - both the first and the second carrier 7 and 8, the receptacles 4 in the profile strips are released in succession from the right to the left by the second carrier 8. The second carrier 8 is set relative to the first carrier 7 in the axial direction in such a way that between the driving lug 10 and the end 11 of the second carrier 8 there remains a passage which is open at the bottom and corresponds to the diameter of one of the rolled stock bars 2 to be distributed (FIG. 3a).

Durch weiteres Verschieben der Verteileinrichtung 6 und entsprechendes fortlaufendes Freigeben der Aufnahmen 4 wird somit ein Walzgutstab 2 nach dem anderen in die freigewordenen Aufnahmen 4 eingelegt, bis alle Walzgut­stäbe in den Aufnahmen der Profilleiste 3 liegen. Das ist in der in Figur 5 dargestellten Stellung der Fall, in der die Verteileinrichtung 6 seitlich neben dem Rollgang angelangt ist.By moving the distribution device 6 further and correspondingly continuously releasing the receptacles 4, one rolling rod 2 after the other is thus inserted into the receptacles 4 that have become free until all the rolling rods are in the receptacles of the profiled strip 3. This is the case in the position shown in FIG. 5, in which the distribution device 6 has reached the side next to the roller table.

Durch Absenken der mit Walzgutstäben 2 gefüllten Profilleiste 3 und gleichzeitiges Herabfahren einer profilierten Niederhalterrolle 12 werden die Walzgutstäbe 2 auf dem Rollgang 1 abgelegt und können in der entspre­chenden Teilung der Kaltschere zugeführt werden. Nach Absenken des unteren Trägers 8 der Verteileinrichtung 6 ist die Einrichtung erneut einsatzfähig und kann nach Abtrennen und Abführen der geteilten Walzgutstäbe 2 mit einem neuen Arbeitszyklus gemäß Figur 2 beginnen.By lowering the profiled strip 3 filled with rolling stock 2 and simultaneously moving down a profiled hold-down roller 12, the rolling stock 2 is placed on the roller table 1 and can be fed to the cold shears in the corresponding division. After lowering the lower support 8 of the distributing device 6, the device is ready for use again and can start a new working cycle according to FIG. 2 after the divided rolled bars 2 have been separated and removed.
