Description

The invention relates to the field of metal forming, in particular to devices for automated slitting of a metal strip with a banded cladding, and can be used in metallurgical, electrical, electronic and other industries.

The purpose of the invention is to increase the speed of movement of the tape, improving the performance of scissors.

FIG. 1 shows the carriage, a general view; in fig. 2 - section A — A in FIG. one.

In frame 1 (Fig. 1), axles 2 are fixed on which carriage 3 is movably mounted. Transverse movement of carriage 3 is carried out from the tracking drive 4 by means of screw 5. Sensors 6 and 7 of the deviation meter 8 are fixed on axes (not shown) on frame 1 The rollers 9, limiting the displacement of the metal tape 10 with the plated strip 11, can be set to a specific width of the tape. Tape 10 is fed to the knife block 12 when manually refilled. The support roller 13 is located under the sensors b and 7, additional guide rollers 14 are located before and after the support roller. The support roller 13 and the additional guide rollers 14 are installed rotating in the carriage walls, the diameter of the roller 13 is determined by the ratio

Tso = (1.3-1.4) 8 _N ,

where ϋο is the diameter of the support roller;

8 _{I am the} diameter of the extra roller.

The ratio of the diameters of the rollers is made from the condition of ensuring the same ₅ rigidity of the guide and support rollers.

In the process of cutting metal tape 10 passes through the guide rollers 14, bends around the support roller 13 and then along the guide rollers goes to the knife

U block 12 cutting, while increasing the speed of movement of the tape in the guide carriage does not cause vibration of the tape. When getting plated strip 11 of the tape 10 in the area of the sensors 6 and 7 occurs

! measurement of unbalance EMF, after amplification of which the electric drive 4 is turned on in a known manner. Depending on the displacement of the strip 1 1 relative to the sensors 6 and 7, the screw 5 moves the carriage 3 to one side or the other,

20 by orienting the strip 10 relative to the base cutting edge of the knife unit 12 for cutting.

Experiments on the proposed guide carriage using known sensor design show that ²⁵ introducing a support roller and additional guide rollers into the carriage can increase the belt speed from 20 to 30 m / min when cutting tapes with a thickness of 0.4-0.63 mm cutting tapes with a thickness of _{30 to} 0.2-0.35 mm - from 10 to 40 m / min, which makes it possible to increase the productivity of scissors.
