SU1232399A1 - Line for transverse pattern cutting of sheet stock - Google Patents

Description

The invention relates to the field of metal forming and can be used for transverse cutting of coiled material, such as electrical steel onto magnetic core plates.

The aim of the invention is to improve the performance and reliability of the device.

Fig, 1 shows a line of transverse cutting of the rolled material, a general view; figure 2 is the same, top view; on fig.Z - receiving storage table.

The line contains an unwinding device 1 strip, a roll feed mechanism 2, first guillotine shears 3, second guillotine shears 4 with fixed 5 and movable 6 knives, receiving table 7 with adjustable MbW stop 8 with limit switch 9 and clamp 10, finished with the possibility of longitudinal moving on rollers 11 along monorails 12, dumping device 13 with stops 14, first 15 (FIG. 2) and second 16 tables storage devices for receiving and stacking the plates. The first storage table 15 is embedded in the LINE along the movement of the strip between the fixed guillotine shears 3 and 4 with the possibility of longitudinal movement on the rollers 11 along the monorails 12 (figure 1) and is designed as a platform 18 with supports 19 of autonomous sections with grooves 20 and bevels 21 (FIG. 3), mounted obliquely with a lift in the direction of the Second guillotine shears 4 on the frame 22 with the possibility of vertical reciprocating movement relative to the frame 22 by means of the pneumatic actuator 23, while the frame 22 is installed with the possibility of reciprocating upatelnogo vertical movement via stepper motor 24 on the platform 25.

The relative movement of the frame 22 and the platform I8 is provided by the respective actuators 23 and 24 on the guide column 26.

Platform 18. is set obliquely (angle) so that its surface is lowered from the side of the guillotine shears 3 relative to the cutting edge of the knife 5, and near the guillotine shears 4 is respectively raised above the cutting edge of the fixed knife 5 (Fig. 3).

Line cross cut material works as follows.

From the softening device 1, the strip (not indicated), for example electrical steel, is fed by the roller feed mechanism 2 to the cutting zone.

Having passed the guillotine shears 3, she moves along the supports 19 of the yoke 18 with the lift in the direction of the guillotine shears 4. The bevels 21 on the stands and the lifting in the direction of the guillotine shears 4 ensure free movement of the strip and its transition for the guillotine shears 4 to the receiving table 7.

When the leading edge of the stop strip 8 is reached with the limit switch 9, the clamp 10 is engaged, which takes hold of the edge of the strip. At the same time, the rolls a and b are turned off, and the roller c is turned on; in the opposite direction, the strip is tensioned. After this, the guillotine shears 3 and 4 are turned on, which simultaneously cut two plates 27 from the strip.

Simultaneously with the lowering of the movable knives 6 of the guillotine shears 3 and 4, the platform 18 is driven down by a drive 23 of the reciprocating movement by an amount H (FIG. 3). The bevels on the fixed knives 5 provide a free cut of the strip and lowering the plate 27 to the platform 18. When the upper cutting knives 6 are returned, the guillotine shears 3 and 4 to the upper position the drive 23 returns the table to the upper position by the value H and the drive 24 vertical pitch movement lowers pad 18 by the amount of strip thickness. Thus, the drives 23 and 24 ensure constant maintenance of the level of the platform 18 of the table-drive 15.

The second cut-off plate 27 is discharged by the reset mechanism 13 onto a storage table 16 for stapling the plates. After dropping, the cycle is repeated.

To change the length of the plates, the lengths of the first storage table 15 and the reception table 7 are retooled. For this, tables 7 and 15 are moved on the rollers 11 to the right (with increasing length). With this stand

19 align the working level of the area 18.
