THYSZEN & COMP, in, MÜLHEIM, Ruhr. Edging device for rolling mills.

Patented in the German Empire on December 12, 1908.

The invention relates to a folding device for rolling mills and other roller tables, in which of one of the working direction of the rollers arranged in parallel, oscillating Shaft arm groups are operated, one of which moves the rolling stock, the other it edges.

The arm groups are perpendicular to the working direction of the rollers according to the length

ίο of the rolled stock to be edged between the Rolling the roller table arranged regularly or intermittently.

The shifting of the rolling stock into the position required for edging and the edging itself happens through the arm groups in a known way, but with the difference, that a support device is raised from the vibrating shaft, which the rolling stock when edging serves as a support and after edging has been performed as a support when lowering, so that preventing the rolling stock from falling. ·

The support device is driven either directly by the cant arm or by a special arm.

The transmission of its movement to the support device takes place under the mediation of a on a guideway moving roller instead, such that a periodically inevitable Movement of the support in the vertical direction is achieved. It is effected in this way that the moved generally only during part of the working movement of the cant arm Support shortly before the point in time at which the rolling stock is attacked by the cant arm will; is pushed over the upper edge of the roller, by virtue of their corresponding to the cross-section and the size of the rolling stock designed to be edged and its height a sideways escape of the workpiece is prevented and after passing the median line of the workpiece through the imaginary plumb line on the edge line, a smooth placement of the Workpiece reached on the roller table.

In the following, an embodiment of the invention is described using two groups of arms, one of which actuates the support device directly.
, Fig. Ι shows a view of the device with two oppositely arranged arms between the rollers.

Fig. 2 shows the arrangement of the device with individual, located between the rollers Arms in a roller table,

A shaft b is mounted under the rollers O ₁ , a ₂ , a ₃ etc. and is set in oscillating motion by the lever c coupled to it. The drive element acts on lever c at point 0. As. such is. In the drawing example, a crank e mounted in d is selected, which is hinged to the Hebei c by means of the rod f. The arms g and h are in rigid connection with the shaft b. g carries a guideway on its upper side, on which the support I, which is laterally guided by the surfaces i and k , is guided. The order is made so that in the rest position the support I does not protrude beyond the top edge of the roller. For the purpose of guiding the support I on the arm g with as little friction as possible, one is free at the point where the support is supported

Claims (2)

movable roller built in. In the drawing example, the drive movement is brought about by a crank drive. It can just as well be derived from a straight line movement or a movement along some irregular curve. ■ The working process of the edging device is as follows: In the crank position shown, the roller path is released for the completely unhindered conveyance of the rolled material. The rolling stock w, in the drawing example with a square cross-section, should now be folded. For this purpose, the crank is moved into the left dead center position y1 in the direction of the arrow. The point 0 is thus brought into position y2, while the outermost points of the arms h and g advance from ft to y3 and from q to yi, respectively. The arm h pushes the rolling stock w in this way to the right over the support I in the drawing example. The guideway of the lever arm g moves away from the roller m on the way from q to y4, but in this lever position the support I is prevented from sliding out by a nose η attached to its upper part. If the crank β is now moved further in the direction of the arrow from the left dead center position yx to the right dead center position Z1, then the point 0 moves into the position z2, the point ft into the position Z3; q describes an arc from position y4 to position Z4. In this way, the arm g meets the rolling stock, which is now in the position W1 and is indicated by dotted lines in the drawing, and lifts it as the movement continues. At the same time, the roll m stored in I comes to rest on the guideway of g. The support I is moved over the upper edge of the roller, prevents the rolling stock, which is in the process of tilting, from giving way and, when the lever movement is completed, serves as a support for the surface of the rolling stock now serving as a support. If the crank is then moved from the right dead center position into the starting position in the direction of the arrow, the points ft and q again assume the position shown, and as the guideway sinks, the support I falls below the upper edge of the roller. By virtue of its supporting surface corresponding to the profile to be edged, it causes it to be gradually withdrawn from the tilted rolling stock and to ensure that it is safely and quietly supported in the position on the rollers, which has been changed by 90 ° from the original position in the drawing example. The support Z is expediently adapted from case to case according to the profile of the rolling stock in the design of the surface to be supported. The contact surfaces of the levers g and h can also be designed in accordance with the profile of the rolling stock. A particular advantage of the invention is that the support I can easily be replaced by simply pulling it out according to the profiles currently being processed. The arrangement of the device in the roller table or the roller table is done in such a way that auxiliary cantilever arms are installed between different devices of the type described. Such a device is shown in FIG. The design is the same as that described, but the support I is omitted. This is justified by the fact that the forces to be absorbed by it are relatively small in relation to the forces required for moving and edging the rolling stock. The overall arrangement is then similar to that indicated in FIG. 2. H1, A2> hs and A4 are the arms intended for moving the rolled material, while arms gv g2, g3, g4, g5 and ge handle the edging. The arms gx to g6 are not all provided with supports I, but only partially, in accordance with the length of the rolling stock, in the drawing example the arms gv g4 and g6. The movement of the edging device takes place either by itself by a special drive motor or is derived from the lifting and lowering movement of the roller table. Ρλ τ ε ν τ - A ν s ρ R ü c η ε: 1. Edging device for rolling mills, in which the displacement and the edging of the rolling stock is carried out by two or more groups of arms moved by a shaft, characterized in that a support (I) is raised from the canting arm (g) or a special arm, which the Prevents the rolling stock from giving way during the edging and is supported after the edging on the surface intended for support. 2.
