    专利说明:

    The invention relates to devices for continuous cutting of longitudinal ribbons, mainly to mechanisms and aggregates that cut metal strips into strips with curvilinear, in particular sinusoidal, edges combined with them.
    The aim of the invention is to improve the quality of finished products and increase the durability of knives.
    FIG. 1 shows a device for continuous cutting of strips of material, top view; Fig 2 - the same, front view; on fig.Z - two cutting cylinder; figure 4 is one of the cutting cylinders; Fig. 5 shows a section of two cylinders in working condition when cutting strips from a belt.
    A device for continuous cutting of strips of material comprises a base 1, on which a base 2 is located, connected through rotation drive means 3 and spindles 4 to a motor. The bed 2 is made in the form of a pair of racks 5, which serve as supports for the upper 6 and lower 7 cutting cylinders.
    The cutting cylinders 6 and 7 of the state of the two shafts 8 and 9, on which several sets of knives are fixed by means of dowels.
    Each set of knives consists of two knives 10 with counter curvilinear cutting edges and two knives 11 with curvilinear cutting edges directed in opposite directions, while the knives 10 on the shaft 8 form cutting pairs with overlapping knives 11 on the shaft 9. Each of the knives 10, 11 is cylindrical in shape with a boring on the side of the end surface with a cutting edge and with an insert 12 of a carbide material on which the cutting edge is formed.
    On shafts 8 and 9 between the knives 10 and 11 there are several sets of gaskets. Each set of gaskets consists of two internal compensating gaskets 13, located in the bores of knives 10 and 11, two bushings 14 mounted on the shaft between the end surfaces of the internal compensating gaskets 13, at least two radially elastic, elastic gaskets 15, intermediate spacers 16, a spacer gasket 17 and two external compensating gaskets 18. An intermediate gasket 16 is installed between the end surfaces of the sleeves. Spacers 17 are mounted on the shaft between the face surfaces of the knives opposite to the surfaces with the cutting
    by edges. External compensating spacers 18 are mounted on the shaft and are located between the end surfaces of the knives opposite to the surfaces with
    cutting edge. Radially elastic thrust pads 15 made of rubber or similar material are cylindrical in shape with end surfaces facing the cutting edges.
    the edges of the knives, the counter face surfaces of these knives, and are mounted on the sleeves 14 between the end surfaces of the knives with cutting edges.
    The driving means 3 of rotation of the cutting cylinders provides for the restoration and reduction to zero of the gap and synchronization of the rotation of the cutting cylinders 6 and 7 and consists of a housing 19 in which a helical gear 20 is located, which interacts with the helical gears 21 and 22 mounted with the possibility of axial movement. Between the wheels 21 and 22 is located a returnable elastic means 23. The driving means 3 is associated with
    shafts 8 and 9 of the cutting cylinders 6 and 7 by means of the spindles 4 for transmitting the synchronous rotation irrespective of the distance between the axes of the shafts 8 and 9.
    The device works in the following way.
    When cutting with a device for continuous cutting of strips of material is elastic in the radial direction, the stop gasket 15 of the upper cutting member
    the cylinder 6 is pressed upwardly by the material 24, while the elastic gasket 15 of the lower cutting cylinder 7 is pressed downwards.
    The gap between the cutting edges of the knives 10 and 11 is maintained and adjusted by intermediate spacers 16 and spacers 17.
    Radially flexible thrust pads 15 having a diameter
    the larger diameter of the knives 10 and 11 are designed to compensate for the cutting forces and thereby reduce the burrs, etc. When regrinding the cutting edges of the knives 10 and 11, their width is compensated for by internal compensating spacers 14 and external compensating spacers 18.
