    This invention relates to saw chains for sawing wood. The purpose of the invention is to increase the strength of the chain. The cutting link of the saw chain contains a U-shaped supporting part 1 with a notch 5 and parallel walls 2 and 3, symmetrical about the 4j axis and the cutting element 17 rigidly connected to the supporting part and made of tungsten carbide, the lower part of which is placed in cutouts 7 and 8 of the support part, and the central protrusion 26 is located between the walls 2 and 3 and the protrusion 28 of the support part 1. 8 Il.

    The invention relates to saw blades.
    Timber for wood smelting and can be used in timber industry.
    The purpose of the invention is to increase strength, achieved through a more reliable base. . On .fig, 1 is shown the support of the cutting unit after stamping; in fig. 2 - cutting element, type of specialization; Fig, 3 - cutting element, id on the side; FIG. 4 shows the cutting link, side view; in Fig.5 is a cutting link, front view; in fig. 6 - cutting blade version, side view; 7 - the same, top view; on. 3 - the same, front view.
    The support part 1, which forms the cutting link, has walls 2 and 3, symmetrical to the axial axis of the axis. In the central part, the support part has a notch. 5 with sector 6, go form an angle (x ;, CI) with 7 notch 7 and 8 and two flaps 9 and 10, .. Wall 2 has openings 11 to 12, pinhole openings m 1 3 and 14 in wall 3. In walls 2 and 3 there are also two half-round cut-outs 1.5 and J6,
    .: Cutting ™ element 1 7 is made of tungsten carbide and has a cutting edge. 18 with radius, sections 19
    and 20 and inclined sections 21 and 22, Ni; kn8, part 23 of the cutting element has a radial surface, the J5 of which is perpendicular to the front 24 and the supporting 25 surfaces. The surface after bending the supporting part 1 along axis 4 is in contact with the cutouts .7 and 8. On the back surface, the cutting element has a central protrusion 26, which extends to the anode with the radial part 23 of the element “The cutting edge sections 21 and 22 are inclined by the angle .4, and

    The sliver 28 forms an arc in contact with the upper part 27 of the protrusion 26. The lower part 23 of the cutting element is located in the notches 7 and 3 of the support part 1. To prevent the cutting element from moving, spot welding can be used in zone 29. However the parts are made by side walls 2 and 3 and by a lintel 28. On the other hand, the connection between the cutting element and the support part can be made by soldering. The cutting element described is used to cut relatively hard materials (oak.
    brick, concrete and aphids). To cut soft materials (sos-a), it is necessary to tilt the cutting edge in relation to the direction-of-motion. link.
    In this embodiment, the support part 30 has a small difference. The holding flaps 31, 32 precede the section with recess 33, leaving space in front of the cutting element 34, which is installed with a tilt from the axis of symmetry 35. The walls 36 and 37 pairs. Allel.y are between themselves and connected by a curved jumper 38 curved in an arc. The cutting element has three. edges 39, 40 and 41,
    In part have. protrusion 42. Excavation. 33 in the support part 30 is designed to fit with. the back surface of the cutting element 34.
    The angle of inclination of the plate S can vary from 0 to 45. Besides; the plate is rotated at an angle Y in the previously specified X limits. It is also necessary to provide cutting links with opposite inclination of the cutting elements 43. When mounting the links, the right and left links are installed alternately, with guide or piercer links inserted between them. Cutting elements can be asymmetrical in one or four 4-meter 44 forms.
    The cutting elements are made of tungsten carbide, titanium carbide or other material with the same hardness. The support part is manufactured from steel with a Vickers hardness of 540-620 at a load of 20 kg.
