Description

one

The invention relates to the processing of metals by pressure and can be used in devices for longitudinal cutting of sheet material.

A device is known for slitting material, preferably thin-sheet, which contains cutting discs mounted on parallel drive shafts, a mechanism for removing burrs and a mechanism for winding cut tapes.

To increase the productivity of the device, the deburring mechanism is made in the form of a knife with two cutting edges, installed between the cutting disks, a winding mechanism across the material being cut and with the possibility of horizontal reciprocating movement by means of, for example, a cam drive. Each cutting edge of the knife parallel to it are installed vertically spring-loaded pressure rollers. In addition, for self-sharpening the edges of the knife of the deburring mechanism, it is made in the form of a dovetail, the ends of which are cutting edges. The winding mechanism in the described device is made in the form of cassettes with parallel axes located one under the other.

FIG. 1 shows the proposed device, an open view; in fig. 2 is a cross-sectional view of a deburring mechanism knife.

The proposed device contains sieve-cutting discs 1, located on parallel

shafts 2 with a drive 3 of their movement, a mechanism for removing burrs in the form of a knife 4 with two cutting edges (in the form of a dovetail), installed across the material being cut and

reciprocating movement by means of, for example, a cam drive 5 connected with a drive of cutting discs, and a mechanism for winding cut tapes made in the form of cassettes 6 with lateral axes located one below the other and also connected with a drive of cutting discs. At each cutting edge of the knife, parallel spring-loaded pinch rollers 7 and eccentrics 8 are installed vertically in parallel with it.

for their adjusting installation. Between the cutting discs and the deburring mechanism, the milling rollers 9 are mounted, and in front of the winding mechanism in the direction of material movement, there are guides

videos 10.

The cutting discs 1 pre-cut a portion of the web material into ribbons that are passed between the guide rollers 9. Then, the chopped ribbons are alternately passed above and below the cutting rollers.
