Abstract

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting sheet material into strips. The purpose of the invention is to increase productivity. The cutting device comprises a roller table 1, cutting rollers 2 fixed by means of axis 3 of a pivot frame 4 with driving 5 mounted on it in two concentric circles and transporting 6 rollers driven by drive 7. Frame 4 is set at an angle to the direction of movement sheet 14. This ensures its twisting between the rollers 6 along a helical line with a pitch equal to the width of the cut-off strip 13. 2 sludge.

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting sheet material into knots.

The purpose of the invention is to improve the productivity of the device for cutting sheet material.

FIG. 1 shows a device for cutting sheet material, general view; in fig. 2 - the same, nlan.

The device for cutting sheet material contains a table-roller table 1, on which the cutting rollers 2 are mounted and fixed by means of an axis 3, a swinging frame 4, on which two concentric circles 10

Turning the frame 4 about the axis 3 sets the angle c, corresponding to the required width of the cut-off strip 13, and fix the frame in this position. The sheet 14 is fed to the drive rollers 5 by means of a table-roll table 1, grabbed by them and fed to the cutting rollers 2. The cut strip 13 is fed further along the straight line, and the sheet 14 is caught by the transport rollers 6 and is rolled between them along a helix. When the front edge of the sheet passes a full turn, the rear edge will exit the zone of the cutting rollers 2, and the front will enter the cutting zone 1) and shifted to the width of the strip 13, and the cutting process will continue in the same

The bones are mounted with drive 5 and transport 15 direction. Thus, at each treading 6 rollers, driven in turn by the front of the front edge of the sheet, it is cut off by the drive 7 by means of chain gears 8 and 9, respectively. The outer surfaces of the rollers 5 and 6 are made, for example, with screw threading and are mutually positioned with the possibility of picking up a sheet and transporting it along a helix with a pitch determined by the angle c and equal to the width of the cut strip. The length of one turn, and

consequently, the diameters of concentric

the circles are selected on the basis of the standard- 25 it is equipped with a frame, a sheet-mounted length, for example, 4 m. The support 10 on the table-roller table is reusable to prevent turning the collar about the axis lying in the plane of the sheet during cutting and ensuring uniformity of cut and perpendicular working width of the strip along its entire length. the surface of the table-roller table, in contact with the Roller 11 and the cross member 12 of the frame 4 predaz- Q with a cut off strip rollers fixed

with one strip until the entire sheet is cut.

Invention Formula A device for cutting sheet material into strips comprising a roller table, a drive, cutting rollers, driving and transporting rollers, characterized in that, in order to increase productivity I are started to regulate the tension of the chain transmission 9. on the frame by means of axes located on two concentric circles, parallel to one another, with an external screw being cut on each of them. The device works as follows. Turning the frame 4 about the axis 3 sets the angle c, corresponding to the required width of the cut-off strip 13, and fix the frame in this position. The sheet 14 through the table-roller and 1 is fed to the drive rollers 5, grabbed by them and fed to the cutting rollers 2. The cut strip 13 is fed further along a straight line, and the sheet 14 is gripped by the transport rollers 6 and folded between them along a helical line. When the front edge of the sheet passes a full turn, the rear edge will exit the zone of the cutting rollers 2, and the front will enter the cutting zone 1) and shifted to the width of the strip 13, and the cutting process will continue in the same direction. Thus, with each revolution of the front crochet from the sheet, it cuts off it is equipped with a frame, which is hinged on the table-roller table with the possibility of being rotated about an axis lying in the cut plane and perpendicular working surface of the table-roller table, contacting the cut strip with rollers with one strip until the entire sheet is cut. Invention Formula A device for cutting sheet material into strips comprising a roller table, a drive, cutting rollers, driving and transporting rollers, characterized in that, in order to increase productivity on the frame by means of axes located on two concentric circles, parallel to one another, with an external screw being cut on each of them.
