Description

The invention relates to the processing of metals by pressure and can be carried out in workshops of rolled metal products of metal panels on sheets and dissolving hoop stripes on steel tapes. Known pini for cutting the sheet, which includes an uncoiler, devices for tensioning and resting the sheet, guillotine shears with knives of a C-shaped form and a device for cleaning the cut ends, and the gears are equipped with a mechanism for turning in the translational movement in the horizontal plane l. However, on such a line it is impossible to cut steel strips into sheets and to dissolve them onto tapes. The most effective isoflowing to the technical essence and achievable result is a unit for cutting steel strips, the contents are installed in the technological line. roll unwinder, straightening machine, guillotine shears, feed rollers, inclined table, straightening machine, shears, and coiler, which are mounted on the idles with the ability to move the perpendicu $ fno axis of the unit. The disadvantage of this unit is the low productivity associated with the expenditure of time for transferring the unit for filling lanes. The purpose of the invention is to increase the productivity of the unit for cutting steel strips. This goal is achieved by the fact that the unit for cutting, steel strips containing the roll unwinder installed in the TexHcno-pgichesky pine correct-bearing machine, guillotine shears, feed rollers, an inclined table, the correct machine, disc shears and a winder mounted on the guide wheels. possibility of installation perpendicular to the axis of the unit, provided with a wiring pillar, mounted on guides coaxially to the wagon, with the possibility of movement perpendicular to the axis of the unit, while the wiring table is kinematically connected with the motor Coy by the lever mechanism. FIG. 1 shows a unit for cutting steel strips, head; in fig. 2 - the same tail avst; in fig. 3 - the same, in the working position | Research Institute of the wiring table. The unit for cutting steel strips consists of 1 rolls installed in the production line of an unwinder, a guard machine 2 and a hypotoe scissors 3 for trimming the ends of the strips. Behind the scissors 3, feed rollers 4 are placed, and an inclined table 5, behind which the machine 6 is placed correctly, feed rollers 7, loop-back SM & 8 and the feed rollers 9 for transferring the steel strip to the disc shears 1O, dissolving the strip on the strips and cutting the side edges. After the disc shears 10 there is a tap winder 11 provided with a rotation rotary motor. The winder 11, the base of which is mounted on horizontal guides 12, the axial assemblies of the MN unit, is equipped with a movement mechanism in the form of a double-acting hydraulic cylinder 13, Kcqinyc of which is fixed on the foundation, and the shanks 14 on the base 15 of the winder 11. In addition, the base 15 of the winder 11 is connected by means of levers 16 with a single fur Kom iM table 17 mounted on the directions with the possibility of movement along the axis of the winder (perpendicular to the axis of the regulator). For example, & .12 of the base 15 of the winder 11, there are kszhtsevye switches that ensure that the winder stops in the working position (Fig. 2) and the wiring stop 17 (Fig. 3) is installed in the working position when the winder 11 is moved out of the assembly line. After the winder 11, the rollers IS, looping machine 19, the right flax machine 20, and the flying rammer 1e scissors 21 for cutting the strip into sheets are supported. After the flying drum shears 2i, the bagging device with the rollers 22 and the conveyor belt 23 is put in place to pack the sheets. The machine for cutting steel strips works as follows. To cut the strip into tapes, hydraulic nipples 13 deliver liquid under pressure. The rod 14 of the gypsum arm 13 pv moves the coiler 11 for the tapes for oonation 15 along the guides 12. The MoTalka 11 and the wiring table 17 connected with it by means of levers 1B take up the position (Fig. 2), in which the drum of the coiler 11 is in the aggregate that aprovo1 table 17 outside the pine.

Moving the motocap And in the direction of II, 12 stops the end of the diskette. The roll is pulled onto reel unwinding 1, the front end of the strip is set in the feed rollers and cut with guillotine shears 3, the cut end is then fed by the feed rollers 4 to the inclined table 5 and dropped into the side trim box. The strip is fed to the conventional machine 6, the feed rollers 7 and the loop loop 8. From the loop 8 loop, I feed the rollers 9 to the disc shears 1O, where it spreads onto ribbons with trimming edges.

The tapes are wound on a winder drum 11. In the gaps between the tapes when winding down the separating rings, they are mounted on a collar roller. After the cutting is finished, the rolls are removed from the coiler 11.

A quick changeover of the unit is carried out for cutting the strips into i sheets. The disc scissors 10 leave

only knives for trimming. The stem 14 of the hydraulic cylinder 13 of the coiler 11 is withdrawn from the line of the aggregate. In this case, the base 15 of the coiler 11 moves along 1A guides 12. Simultaneously with the coiler 11, the wiring table 17 connected with its base 15 by means of the I levers 16 moves. The wiring table 17 is moved along its direction and is inserted into the aggregate line. The movement of the wiring table 17 is terminated by limit switches. In this case, the axis of the OO conductor-table 17 coincides with the axis of the aggregate (Fig. 3). On the coiler 11, it is possible to carry out repairs and maintenance during the operation of the machine ,.

After these preparatory operations, the strip is loaded into the unit, sliding along the wiring table 17 and pulling debris 18, the loop 19, and passing through the correct machine 20, goes to the flying drum scissors 21, which cut the strip into sheets. The sheets fall on the face of the porter belt 23, the envelope of the roller 22, and are folded into packs.

Compared with the famous device. In particular, the use of the proposed shadow image improves the productivity of the unit for cutting steel strips.
