SE453268B - DEVICE FOR DISCONNECTING CURRENT OPERATING GOODS AFTER A HIGH SPEED SAX - Google Patents

Description

20 25 30 35 453 268 2 -f- leads the front and end snout piece as well as the roller vein in therefore provided control channels. The exit section consists of three in one plan next to each other catching funnels with subsequent guide tube. Due to the cutting technology of the knife heads, the part is pivotable in the horizontal plane. in order to resp. arteries have a control channel available through the corresponding positioning.

When testing the function of the solutions shown, it has shown that the vertical position of the wedge down with respect to the horizontal sontella roll goods movement through transport in the caliber as well as with regard to the vertical through the cutting process The vein movement is unfavorable and leads to severe wear on the wedge- This in turn causes an anxious transport of the rolling mill and leads down in view of these high rolling stock speeds> 50 m / s often to technical disturbances.

The object of the invention is to increase the use value for a wire rolling mill and lower the scrap portion when snatching off valsâdern.

The object of the invention is to design the exit part accordingly the high-speed scissors constructively so that for steering it divided roller vein arrange and design the wedge in its position and shape so that it adapts to the lateral movement of the calibers and the simultaneous vertical movement at the clip.

According to the invention, the task is solved by in a solid exit part, which accommodates the rolling stock control channels as section, a vertically displaceable backing part is provided. which the scrap and rolling stock channels occupy the mirror image such as double partially overlapping subsections.

In this case, it is constructively arranged that they part existing. towards the horizontal with equal and mirror-image-facing angles. provided partial the sections for the scrap and rolled goods channel channels are designed equal in height and in width tapering in the wire running direction. The said angles a and ß include depending on the rolling 10 15 20. 25 30 35 * 3 4-53 268-. the rolling speed and the rolling program an oil range of 20 ' ... 60 °.

The invention is described in more detail in connection with the appended claims Figures 1-7, where: Pig. 1 shows the schematic motion diagram when snatching the vein of the vein, Fig. 2 principle of the exit part for snatching the vein front end. Fig. 3 shows the schematic course of movement when snatching the end of the end. Fig. 4 shows the principle of the exit part for snatching the end end, tig. The exit part seen from B according to Fig. 6, tig. 6 section C-C of the exit part according to Fig. 5 and Fig. 7 finally shows section A-A of the exit part according to Fig. 6.

According to Fig. 1, the pivoting arrangement arranged in front of the scissors runs the tube and the beginning of the roller vein l into the guide heads led into the the inlet plane I on the exit part 3. In order to initiate cutting during the race the roller seed 1 is moved from position a to position b 1 the rocky plane II. When protruding on the upper knife, press on cut the end of the lower snout end down to position c and the tip of subsequent roll goods is brought upwards position d. Genoa transverse transport in the caliber of the knife heads collars the rolling stock vein in position e 1 planet III, sol is in the rolling the straight direction of the gene.

Corresponding to Fig. 2, the beginning of the roller vein 1 runs into the exit the channel 2 'of the part 3 and is moved by oscillation from the plane 1 in in planet II. When cutting, raise the trailing lower knife up the subsequent tip. Through the true cross-border 10 15 20 25 453 268 4 ~ = the port of the roller vein in the caliber is obtained a resultant movement. which occurs from position b approximately perpendicular to the wedge 4 '. This ensures the next contact between the roller vein l and wedge 4 '. In the channel 5 'the roller head 1 slides the plane III. Pig. 3 and 4 show the course of events resp. the mode on wedge 4 'when snatching the roller end end. The device is a mirror image of the snatching of the spirit. The different steps takes place in a corresponding mirror image sequence from left to right Right. The stage part 6 is then vertically displaced in the exit. part in relation to the rolling line. so that the scrap and roller core channels 2 'and 5' are in the positions for the existing channels 2 and 5 before snatching the the.

Figs. 5 to 7 show the exit part according to that in Figs 4 described procedure. The channel control and wedge device is incorporated in the sliding part 6. len 6 is vertically displaceable in one arranged on both sides bolt guide 7 by naneuvering a working cylinder 8 in it fixed exit part, so that the nan can change the mirror image arrangement of the channels, such as the scrap channel 2 'and 2' and the roller vein channel 5 '. 5 'likson also the direction of inclination a resp. ß on wedge 4 'resp. 4 'as it changes or closing should be snatched.

Claims (3)

10 15 s 453 26.8 Patent claims Device for deflecting running rolling stock after a high-speed scissors. preferably in a wire rolling mill. k ä n n e - t e c k n a d of that in a fixed exit part (3). which occupies the rolling stock control channels in subsections. a vertically displaceable backing part (6) is arranged. which occupies the scrap and rolling stock channel (2, 5), arranged mirror-image-like son double partially superimposed sub-sections. Device according to Claim 1, characterized in that the sub-sections of the scrap and rolled goods arterial channels (2 '. 2'. 5 ') are provided with the angles which are horizontal in the set-up part (6) and the horizontal down equally large and mirror-image. 5 ') are designed equal in height and width tapering in the wire running direction. Device according to claim 2, characterized in that the angles a and ß, depending on the rolling speed and the rolling projection, comprise an area of 20 '... 60 °.
