    An apparatus is disclosed for precision slitting of metallic coil stock into multiple continuous lengths of wire, wherein the resultant wire is characterized by a small cross-sectional area. The apparatus comprises means for guiding coil stock into a pair of revolving monolithic cutter rolls and means for collecting the slit wire. The rolls are positioned in engaging relationship and each roll contains a plurality of lands and grooves so that stock can be slit with an aspect ratio of less than five.

    专利说明:

    The invention relates to the processing of metals by pressure and can be used in industry for precision slitting of a thin material, such as tin. A device for slitting, comprising a decoiler, disc shears, and a winder is known. Disk shears have two parallel shafts on which disk knives are mounted, separated by C1 sleeves. For cutting material less than 1 cm wide, the quality and cutting accuracy is low. A device for longitudinally cutting a coiled material is known, which contains two tools interacting with each other, one of which is made in the form of a knife sleeve with flanges, grooves and annular protrusions with cutting edges 2 placed on its surface. However, when cutting extremely narrow strips, the thickness of the knives is very small and their strength is low. In order to increase the strength of the structure for cutting extremely narrow strips less than 1 cm wide, another tool is also designed as a knife sleeve with annular protrusions having cutting edges, with grooves and flange located on its surface, with the protrusions of one tool located in the grooves of another Tool.Rands at least three times wider than the protrusion. The grooves are made with radius sections connecting their bottom with annular projections. In Fig.1 schematically shows the proposed device, a General view; figure 2 - knives, a general view; Figs. The same section; figure 4 - installation of overlapping knives; Fig. 5 shows the execution of guides; on figb - the device in isometry with the cut strips. The device comprises an uncoiler 1, disk shears 2. in the form of a bed 3 and two knife bushings 4 and 5, seated on shafts B and 7, rotating in opposite directions, guides 8, located on the front side of the scissors, and a winder 9 in the form a number of coils 10, 11 with a drive 12, a tensioning device 13 in the form of a friction clutch and a node. 14 cross feed to evenly distribute the chopped ribbons on the coils. Knife sleeves 4 and 5 are made of alloy tooling, have a cylindrical shape and an axial hole 15. Knife sleeves 4 and 5 are attached to shafts b and 7 by means of screws, nuts, etc. The knife sleeves 4 and 5 have annular protrusions 16,17 with cutting edges 18, separated by grooves 19,20 and the flange 21,22. The annular projections 16 of the knife sleeve 4 are included in the grooves 20 of the knife sleeve 5 by an amount, and the annular projections 17 of the knife sleeve 5 enter the grooves 19 of the knife sleeve 4 by the same amount 6 and called the overlapping of the blades. In some cases, t may be zero. The annular protrusions 16, 17 have a flat horizontal portion 23 and two vertical walls 24.25, which are joined by a reshous portion 26 to a bottom 27 of the groove. The width of the grooves 19, 20 is greater than the width W of the annular protrusions 16, 17 by the size of two side gaps D. The size of the side gap depends on the thickness and mechanical properties of the material being cut. The strength, rigidity and wear of knives are related to the value of the ratio H / W, where H is the height of the annular protrusion. The ribs 21, 22 are approximately three times as wide as the projections 16,17. This gives better support when grabbing material. The guides 8 (, FIG. 5) comprise a base 28 on which fixed vertical cylindrical rods 29, idle vertical rollers 30 and driven horizontal rollers 31 are mounted. The rollers can be made of tungsten carbide.
    The device works in the following way.
    The material roll is placed on the unwinder, and the strip 32 is filled into the guides 8, the disc shears 2 and the winder 9. The shearing of the material on the shears takes place. When cutting hard and brittle material, the overlap is set to zero. During the longitudinal cutting process, the cut ribbons 33.34 are shifted into the grooves
    19.20, and from them they fall through the tensioning device onto the coils 10.11. On this device, ribbons with a width-to-thickness ratio of -6 less than 5 are cut, and the cross-sectional area is less than 4.5. You can cut the ribbons 33.34 with the ratio and cross-sectional area less than 1,. A tin roll was cut with a thickness of 0.254 mm and a width of 5.8 mm for 24 ribbons. The cross-sectional area of the ribbons was 6.45. 10 cM ratio B / i P.
