PATENTAMT.PATENT OFFICE.

Die bisher üblichen Vorrichtungen zum Richten von Universaleisen richteten den Stab nur auf hoher Kante, während das Richten auf der flachen Seite von Hand durch Hämmern geschah. Die vorliegende Erfindung soll auch letzteres maschinell verrichten. The previously common devices for straightening universal iron straightened the Rod only on high edge while straightening on the flat side by hand happened by hammering. The present invention is also intended to machine the latter.

Die Richtbank f ist in der Walzrichtung hinter dem Walzwerk angeordnet und besitztThe straightening bench f is arranged in the rolling direction behind the rolling mill and has

ίο eine entsprechende Länge. Sie hat auf der Richtseite eine Nase oder Rippe k, gegen welche der zu richtende Stab, welcher noch rotwarm sein muß, gedruckt wird. Um denselben auch von oben drücken zu können, sind Druckplatten α angeordnet, die in eigentümlicher Weise bewegt werden, indem sie durch ein Verbindungsstück b an die Hebel c angelenkt sind. Von den Hebeln c ist in gewissen Abständen eine Anzahl auf den Wellen d neben der Richtbank / angeordnet, welche Wellen d durch hydraulische Zylinder oder Zahnradvorgelege in eine oszillierende Bewegung gesetzt werden.ίο an appropriate length. It has a nose or rib k on the straightening side, against which the rod to be straightened, which must still be red and warm, is pressed. In order to be able to press the same from above, pressure plates α are arranged, which are moved in a peculiar manner in that they are hinged to the lever c by a connecting piece b. A number of the levers c are arranged at certain intervals on the shafts d next to the straightening bench /, which shafts d are set in an oscillating motion by hydraulic cylinders or gear transmission.

Hierbei werden folgende Stellungen des Mechanismus erhalten: Die punktierte Stellung ι (Fig. 1). In dieser Stellung tritt der ganze Mechanismus so weit zurück, daß seitwärts von der Richtbank so viel freier Raum verbleibt, daß man neben der Richtbank entlang laufen kann. Zu diesem Zwecke ist die Welle d unterhalb der Richtplatte angeordnet. Anstatt der Stellung 1 von Fig. 1 wäre auch noch eine tiefere Lage des zurückgeschlagenen Mechanismus denkbar, in welcher er vollständig unter Hüttensohle verschwunden ist. Dies wäre notwendig, wenn der gerichtete Stab nach links von der Richtbank abgezogen würde.The following positions of the mechanism are obtained here: The dotted position ι (Fig. 1). In this position the whole mechanism steps back so far that there is enough free space to the side of the bench that you can walk alongside the bench. For this purpose, the shaft d is arranged below the straightening plate. Instead of the position 1 of FIG. 1, a lower position of the pushed back mechanism would also be conceivable, in which it has completely disappeared under the hut sole. This would be necessary if the straightened rod were withdrawn from the straightening bench to the left.

Durch Rechtsdrehen der Wellen d kommen die Hebel c und der daran angelenkte Mechanismus in die Stellung 2 (Fig. 1). Die Druckplatten α haben sich in dieser Stellung auf den soeben fertig gewalzten und auf die Richtbank f beförderten, noch glühenden Stab m aufgelegt. Hierbei werden die Kanten des Stabes ni einerseits von der vorstehenden Nase k der Richtbank f und andrerseits von entsprechenden Nasen η an den Druckplatten a eingezwängt und der Stab selbst von den letzteren auch von obenher gedrückt, weil der in schräger Richtung durch die Verbindungsstücke b übertragene Druck sich in eine Horizontal- und Vertikalkomponente zerlegt.By turning the shafts d to the right, the levers c and the mechanism linked to them come into position 2 (FIG. 1). In this position, the pressure plates α are placed on the still glowing rod m , which has just been rolled and transported to the straightening bench f. Here, the edges of the rod ni are constrained on the one hand by the protruding nose k of the straightening bench f and on the other hand by corresponding noses η on the pressure plates a and the rod itself is also pressed from above by the latter because the pressure transmitted in an oblique direction through the connecting pieces b broken down into a horizontal and a vertical component.

Der Stab ni ist in Fig. 1 und 2 in der größten Breite dargestellt, wie ihn das Walzwerk walzen kann; wäre er schmäler, so würde jede andere Breite von den Druckplatten α an der Kante erfaßt werden, indem die Hebel c die Stellungen zwischen 2 und 3 durchlaufen und die Druckplatten d vorwärts schieben. Die Stellung 3 entspricht der kleinsten Breite der Stäbe, welche auf der Richtbank gerichtet werden soll. Durch die Beweglichkeit des Mechanismus ist ersiehtlieh, daß sich die Richtvorrichtung auch jeder beliebigen Dicke der gewalzten Stäbe anpaßt.The rod ni is shown in Fig. 1 and 2 in the greatest width as it can roll the rolling mill; if it were narrower, every other width would be detected by the printing plates α at the edge by the levers c passing through the positions between 2 and 3 and pushing the printing plates d forward. Position 3 corresponds to the smallest width of the rods that are to be straightened on the straightening bench. The mobility of the mechanism shows that the straightening device can also be adapted to any desired thickness of the rolled bars.

Claims

As can be seen, the essential feature of the described arrangement is through an intermediate member b. In addition to the arrangement shown by lever mechanisms b, c and d, the machine could also be set up so that hydraulic cylinders would be arranged in the direction of the handlebars b in positions 2 and 3 accordingly. The force exerted by these pistons would similarly be transmitted through the handlebars b to the pressure plates α in the oblique direction. The lever arrangement of FIG. 1 is detailed in FIGS. 2 and 3. In the straightening bench shown there, the bars m should only be withdrawn to the right; it is therefore not a lower position of the lever mechanism, as mentioned in detail, and one is content with the dotted position in which the pressure plates α are folded up from the straightening bench f so that the strips coming from the rolling mill slide onto the straightening bench can. Fig. 2 shows a section through the straightening bench, Fig. 3 shows the plan of a short part of the machine. The shaft pieces d are about 4 m long and repeat themselves according to the length of the straightening bench. Each of the shafts d has two levers c, to each of which an intermediate member b is articulated. The parts α form long plates which have protruding lugs η on the lower surface on the left, which can slide in slots / which are recessed in the straightening bench /. These noses η grasp the rod in from the side and press it against the nose k of the straightening bench. In Fig. 2, the widest strip is also shown. In the case of narrow strips, the finger-like plate α passes with the fingers or ribs ο through the recesses ρ in the rib or nose k of the straightening bench f. The pressure on the flat side is thus exerted on the rod by the fingers or ribs 0 of the pressure plates, which is why these ribs are arranged at short distances from one another. The rotary movement of the shaft d is brought about by hydraulic cylinders s. A counterweight t brings the whole mechanism back to the dotted position after it has done its job. According to the width of the rods to be straightened, two hinge points χ and y in Fig. Ι are provided in the straightening plates α. Point y is used for straightening wide bars, point χ for straightening narrow bars. Since the repositioning of the bolts χ and y would cause a stay, the intermediate pieces b in the embodiment according to FIG Intervenes as required and transfers the pressure there. If the pans y are selected as the points of impact, the pressure transmission is suitable for wide strips m, while the pans χ are suitable for narrow strips. When the mechanism goes back, the hook-like ends of the intermediate links b grasp into corresponding ears on the pressure plates a. Pat ε ν τ claims:

1. Straightening bench for flat iron coming directly from the rolling mill, so-called universal iron, characterized in that a number of pressure plates (a) against the still glowing workpiece (m) to be straightened on the straightening bench ff ) by means of intermediate links or articulated pieces (b) be pressed in an oblique direction.

2. An embodiment of the machine according to patent claim 1, characterized in that the pressure plates (a) are connected by articulation pieces (b) to the ends of levers (c) , which levers (c) by shafts (d) against the workpiece be moved there.
