Description

The subject of the invention is a device for the distribution of strips of steel after cutting them on the flying sheepskin drum shears.

The proposed device allows the use of volatile workers together with refrigerators and other similar units required by them to pre-cut the rolled strips into several parts and distribute them along several strands of the trough or direct them.

This is achieved through the use of an auxiliary movable chute, and the reciprocating movement from the rod connected by means of a lever and a disk to the crank mechanism of the scissors is reciprocated.

FIG. 1 shows a schematic diagram of the proposed device; in fig. 2-sketch of the drive unit of the movable tray.

Flying shears are made in the form of two drums with knives 1, driven by electric motor 2 by means of two niecTeren 3 v (4. Upper gear 3 rotates in the non-movable body 5, and the lower one in the rocking body 5, resting on the movable support 7. For production When cutting, it is necessary to move the wedge 8, on which the support 7 rests, to the extreme right position, at the same time the 1 pesterni 3 and 4 engage the sheath / carry out the cut.

The movement of the wedge 8 produces a separate crank-crooked mechanism, consisting of an electric motor 9, a worm, a gearbox 10 of the shaft 11, a crank 12, and a pulley 13.

For distributed cut knots across several (in this case two meters) chutes, a movable tray 14 is applied, receiving a reciprocating movement from rod 15 connected by means of lever 16, a disk and a pair of cylindrical wheels 17 with a crank rod. m scissors mechanism. The disk 18 at the junction with the lever 16 and. Has a groove 19, made in a vnde closed curved curve.

The period between the production of cuts is regulated by setting the movable wedge 8 by changing the length of the pull rod 13. The same wedge is used to combine the operation of the shears and the device for distributing the cut strips.

The electric motor 5 for the drive of the crooked 11 O-1 platun 11 O mechanism is started up at the time of the cutting of the IIOMOHiH locking ring 20, which makes it possible for the engine to start only after taking up knives / the desired position. ,

The proposed device operates in the following way.

The strip - at the exit of the rolled mill is sent by a moving lot: km 14 to one of the streams of the chute 21. As it passes through the chute, the strip presses a limit switch that gives a current pulse to start the electric motor 9 (through the locking ring 20). After starting the engine, the l 9 is set in motion by the Kli 8 and the movable chute 14. In this case, the cutting of the strip is driven and the movable chute 14 is set against the other stream of the chute 21 of the refrigerator. After production of the cut, the wedge 8 returns to its original position, the cut strip goes into the fridge, and the front end of the new strip goes to. another stream gutter refrigerator-. At the next cut, the cycle is repeated.

Subject invention

Claims (3)

1. A device for distributing steel strips after cutting them on drum-type flying scissors, which is HJ. This is due to the fact that, in order to distribute the cut strips alternately along individual streams and chutes of the refrigerator, an auxiliary directional tray is installed, receiving a reciprocating motion from the rod connected by means of a lever and a disk with a curved-crank mechanism. Press down 2. The form of the device according to claim 1, in connection with the fact that the disc, which is not connected to the lever, has a groove made in the form of a closed shaped curve. 3. A form for carrying out a device, but clause 1, that is, so that, in order to combine the operation of scissors and devices for distributing the cut strips, a movable wedge is used, including wringing scissors and moving with crank mechanism
