The invention relates to the processing of rolled products.

Known scissors for cutting jmcTOBoro mother alapo auth.St. No. 389894, containing a keeper knife, mounted on the cross beam, and a movable knife mounted on a slide, which is moved along the vertical bed guides under the action of a wedge mechanism in the form of two wedges, one of which is rigidly fixed to the scissors support, and the other is fixed on and its bevel has a slope in the direction opposite to the bevel of the wedge associated with the caliper.

Such scissors are inconvenient because they are difficult to change nzzhe.

The decisive feature of the proposed scissors is that the movable knife support is connected to the vertical bed guides by means of composite clips, and the fixed knife is fixed on the traverse with the help of an additional support installed with the possibility of reciprocating movement from the individual drive of the cutting edges of the knives and connected with the main caliper by means of ryugul suspensions, sharpy fixed on the main caliper.

The movable knife 1 and the stationary knife 2 are fixed respectively on the drive main caliper 3 and the non-drive supplementary caliper 4. The drive gate 3 is supported by means of a spring device (not shown) located at the bottom inclined lioBepxxnt 5 below on the seat B associated with the ground shaft. TShndrom 6 stem 7 composite rollers 8, interacting with the wedge number in the front part of the bed 9. Non-righteous sample 4 is placed in parallel lines 17 on the plane of the rails and rails 11, equipped with rollers 12, on which spztpor t 4 is supported by its displacement and side for the mixture of НОЖТТЙ. In the working position, the caliper 4 is pressed to the corresponding plane of the guides 10 by the eccentric clamp 13 and

fixed in them in the tangential direction of the squeezing rings 14.

To move the caliper 4 to the side, a rack and a gear 15 is provided. The calipers 3 and 4 are interconnected by means of suspensions, including bolts 16, loosely mounted in the holes of the non-driving caliper 4, and forks 17, which are threaded to the bolts 16, and mi 18 - with a caliper 3. The position of the heads of the bolts 16 relative to the bearing surface of the crosspiece 11 is adjusted so that they do not abut against the non-driving caliper during the operation of the scissors.

In order to allow the calipers to extend from the working area to the side while the knives are being replaced by vertical guides} 1x19, along which reciprocating movement of the drive caliper 3 takes place and the cut is realized, the composite OS: x .-, 2Q with adjustable guides.

To change the blades, the side gap between the wedges 24 and 25 is first increased by their vertical movement due to the rotation of the pressure and squeezing bolts. In this case, such an operation is performed only on the side of the shears into which the supports for changing knives will be displaced. Then two crankshaves 26 (on one of the tracks 19) are removed, and on the other two wings (on the second guide 19 of the same OUYMA) the bolts are loosened, after which the holder is turned around the guide (see Fig. 5), The rod 7 is retracted to the idle position so that the drive from the port 3 is freely positioned on the bolts 16 of the suspensions, and the inclined planes 5 of the driving squirrel 3 pass through the support rollers 8, forming a certain gap. After this, the non-driving caliper 4, by the rollers 12, from the drive of the rack and pinion gear 15 moves to the side from the working area, the driving caliper 3 brought to it is carried away

and image console. The end of the movement is fixed by the stop or terminal sup: a switch (not shown in the drawings).

After the blades are replaced, all the parts return to their original position, after which the knob clearance is adjusted. The clearance adjustment operations are performed laterally through the openings between the crosshead and the bottom of the frame.
