Device for transporting rolled material from a roller mill to a cooling bed

The invention relates to a device for transport rolled material from one behind an end roller mill arranged scissors to form a cooling bed with two or more tubular guides behind the scissors are arranged and the cut rods-Absohnitte record, fed via a switching device longitudinally guided guides and then, one Device are carried out in which the rod sections are delayed in order then to a cooling bed fall «

arise in increasing the final rolling speed by the fact that one does not have sufficiently simple and reliable scissors and transport devices that led from the end roller mill to the cooling bed.

The problem becomes clear from the following figures; A Bar section cut for the cooling bed with a weight of G kg and a speed of Y m / a indicates the energy content

The devices described here are identified in that the longitudinal guides are rotatable from arranged sets of guide tubes exist, each set of which has guides in different Distances (R1, R2, R3 and R4) from the pivot point are that, furthermore, these guides of each set converge or diverge at the same distance (R5) from the fulcrum, and that the rods are passed from here to subsequent drum sections, namely between External guides on these drum sections in Are arranged in the longitudinal direction, where the rod sections are delayed, if necessary by additional means, whereupon they fall onto the cooling bed.

An embodiment of the invention is shown in FIGS 6 shown, namely shows

In Pig, 1, 5 denotes an end roller frame, and 6 denotes a guide tube with a compressed air cylinder 7 * which is located in front of a pair of scissors 8. The first rod section is passed by means of a guide tube 9, together with compressed air cylinder 10 through a tube 1, namely to a arranged on a drum tube 21 or · 3. te "of the next rod section passes into a guide tube 9 'with compressed air cylinder 10 This can be done, for example, in such a way that the cylinder 7 pivots the guide tube 6 into two different positions is fed to the guide tube 9, and then the cylinder 10 has changed the position of the guide tube 9 in such a way that this rod section is conveyed through a tube 3 to tubes 23 or 31. The next rod section enters ^{the guide tube 9 1} , and then the cylinder 10 * has changed the position of the guide tube 9 'in such a way that the rod section is conveyed through a tube 4 to tubes 24 or 31, etc.

In Fig. 2 the arrangement of the guide tubes 21, 22, '25 -' and 24 around the rotatable shaft 26 is shown, and this arrow also carries and rotates a: '^; Switching disk " 12 (Fig. 1) · The shaft 26 is provided with flanges 25, which are used to hold the guide tubes; it is mounted in brackets 13 and 14 and is cooled by means of supplied water 11, which also has drum sections 41 (Fig. 4) - cools *

fig · 4 shows a section through the drum section 41 with pedestals 14 · It also shows that Rod sections 45 have been conveyed into 'grooves of the drum section, and like these on a cooling bed 44 fall with a rust-like toothed surface The drum sections 41 can be completely or partially filled with cooling water, as indicated at 43

Around the point of contact between the pole sections and to enlarge the drum can be under high pressure “Dividing water at 46 like a curtain along the pole sections be sprayed on, and in this way the friction is increased along the deceleration path S, while at the same time the delay time t is reduced, which are required because a certain cooling is required the rods reached »In this way, the braking distance and the braking time is reduced to a fraction, compared to the friction conditions caused by the dead weight the rod sections come into being »

This enhanced delay method can be used with Advantage can be used to achieve a fine adjustment of the braking distance, to the extent that the «Stan—

Figures 5 and 6 show the mode of operation of the switching disk 12. The tube 1 (Fig. 6) is provided with a sleeve 61 which can be moved in the longitudinal direction * by means of an inclined pull rod _s which is coupled to a spring or a cylinder, by means of which a tensile force PI is supplied. In addition, the sleeve 61 is provided with a fixed stop 62 which is pushed back when an articulated lever 64 comes into contact with it, which is attached to a stand 66 by a spring 65 If the switching disk 12 rotates according to the arrow 51 in FIG. 5, the drill 1 and the sleeve 61 follow the switching disk as it rotates until the sleeve 61 comes into contact with the articulated lever 64. After a few degrees of further rotation, the stop 62 this stop and the sleeve 61 are withdrawn and thereby come out of engagement with a receptacle 67j into which the pipe 1 with the sleeve 61 was pushed in by the tensile force P1, as indicated by the dotted L age can be seen in Fig. 6 · In this case the articulated lever 64 assumes the dotted position. During the further rotation, the pipe 2 is forced to carry out the same movements.

In Hg. 6, the position of the pipes 1 _r 61 is shown with solid lines, namely immediately before the rotary movement 51 of the switching disk by means of the articulated lever 64 has pushed the sleeve 61 backwards so far that it disengages from the receptacle 67. The tensile force P1 then pulls the tubes 1, 61 into the dotted position, so that the sleeve is guided into the next receptacle 67, being displaced towards the switching disk. In the dotted position, the next rod section can be pushed through the switching disk "12 into the drum tube 21, as indicated by the arrow 70.
