    Einrichtung zur vertikalen Verstellung der Vertikalwalzen in Universalwalzwerken mit festliegender unterer und einstellbarer oberer Horizontalwalze.   



   Eine Art der Herstellung von Formeisen, z. B. Doppel-T-Trägern, insbesondere von solchen mit parallelflächigen Flanschen, besteht darin, dass das Walzgut doppel-Y-förmig in einem Universalgerüst unter Anwendung von zwei Horizontal-und zwei Vertikalwalzen ausgewalzt wird. Dieses Verfahren ist im Prinzip in Fig. 1 dargestellt. In dieser stellen   Li   und B die beiden Horizontal-, 0 und D die beiden Vertikalwalzen dar. 



   Hiebei ist es notwendig, die Vertikalwalzen C und D bei jedem Stich in vertikaler Richtung so einzustellen, dass der stärkste Durchmesser der Vertikalwalzen genau auf die Stegmitte des Profils drückt, da sonst infolge der ungleichmässigen   Druckgcbnng die Uer-   stellung des Profils in den gewünschten Abmessungen ausgeschlossen ist. 



   Der Gegenstand der Erfindung ist in Fig. 2 beispielsweise im Vertikalschnitt dargestellt. In dieser stellt a den Walzenständer dar, in dem die beiden Horizontalwalzen b und c sowie die Vertikalwalzen d gelagert sind. Das Heben und Senken der oberen Horizontalwalze c geschieht durch den hydraulischen Zylinder e, der vermittelst der Stangen f und g die   Einbaustücke 1 durchsetzt, in   denen die   Wallon d   gelagert sind. Die Höhe der Einstellung der Walze c wird durch die Druckspindeln i, die im Ständer a ver- 
 EMI1.1 
   Einbaustücke     l   drücken und diese mitsamt den Vertikalwalzen d tragen.

   Die genaue Einstellung der Einbaustücke   l   in vertikaler Richtung geschieht durch die Querhänpter q und die   Druckstangen r und   s, die auf die   Einbaustücke I   von   ohen   drucken. Die Qu'r- 
 EMI1.2 
 darin gelagerten Vertikalwalzen d stets sich um einen Betrag heben oder senken, der gleich ist der Hälfte des Masses, um das die Horizontalwalze   ('in vertikaler Richtung   verstellt wird. 



   Auf diesem Wege ist die Möglichkeit gegeben, durch   Veränderung   des   Verhältnisses   der Gewindesteigung der Druckmutter k das Verhältnis der Verstellung der Vertikalwalze d zur Horizontalwalze c in vertikaler Richtung beliebig zu wählen.

    Device for the vertical adjustment of the vertical rollers in universal rolling mills with fixed lower and adjustable upper horizontal roller.



   One way of making cast iron, e.g. B. Double-T-beams, especially those with parallel flanges, consists in the rolling stock being rolled out in a double-Y-shape in a universal stand using two horizontal and two vertical rollers. This method is shown in principle in FIG. In this, Li and B represent the two horizontal rollers, 0 and D the two vertical rollers.



   In doing so, it is necessary to adjust the vertical rollers C and D with each stitch in the vertical direction so that the strongest diameter of the vertical rollers presses exactly on the web center of the profile, otherwise the uneven pressure will prevent the profile from being created in the desired dimensions is.



   The object of the invention is shown in Fig. 2, for example, in vertical section. In this a represents the roll stand in which the two horizontal rolls b and c and the vertical rolls d are mounted. The upper horizontal roller c is raised and lowered by the hydraulic cylinder e which, by means of the rods f and g, passes through the chocks 1 in which the wallons d are supported. The height of the setting of the roller c is determined by the pressure spindles i, which are located in the stand a
 EMI1.1
   Press chocks l and carry them together with the vertical rollers d.

   The exact adjustment of the chocks l in the vertical direction is done by the cross hangers q and the push rods r and s, which press on the chocks I from ohen. The Qu'r-
 EMI1.2
 The vertical rollers d stored therein are always raised or lowered by an amount which is equal to half the amount by which the horizontal roller ('is adjusted in the vertical direction.



   In this way, there is the possibility, by changing the ratio of the thread pitch of the pressure nut k, to choose the ratio of the adjustment of the vertical roller d to the horizontal roller c in the vertical direction as desired.
