    This invention relates to a circular saw blade for cutting wood, wood products, and the like. and can be used in forestry and woodworking industries. Circular saw blades must have a certain intrinsic stress if their working properties meet practical application requirements. The self-stress is usually created by hammering the saw blade with the blade or by applying an annular zone with the help of pressure rolls or by compressing the material with inductive back pressure rings. As a consequence of this compaction of the material, only a tangential tensile stress arises, but not radial, which contributes to the stability of the saw blade. Striking a hammer is very difficult and time consuming. som In particular, these shocks cannot be applied precisely at a certain place on the saw blade and with exactly this strength, which can lead to a significant increase in tolerances and, at the same time, during serial production to different quality of saw blades. The application of the annular zone is associated with the disadvantage that the amount of compaction is limited, since, depending on the thickness, type of material and size of the web, undesirable deformations can occur. A famous circular saw for cutting wood containing a sawing blade of constant thickness with a central hole. At the periphery of the blade there are cutting teeth with plates of hard alloy, and its circumferential surface has waves, the distance between which increases in the direction from the central part of the blade to the periphery 1. However, the saw is characterized by insufficient rigidity, which affects the cleanliness of the cutting and reliability of the design . The purpose of the invention is to increase the reliability of the design. The goal is achieved by the fact that the web has additional waves that are located coaxially with the base in the radial direction, and flat portions that are located between the waves in the radial and circumferential directions, and the width of the waves in the circumferential direction is 15-30 °. between adjacent waves in the circumferential direction is less than the width of one of these waves, and the waves are oval, triangular or trapezoidal in shape. In FIG. 1 shows a circular saw blade, a general view {see. 2, section A-A in FIG. one; in fig. 3 shows an embodiment of a circular saw blade in FIG. 4 - section bb in fig.Z; in fig. 5 shows a section B-B in FIG. 3; in fig. 6 - 10 - saw blades in the variants of their execution, cuts; in fig. 11 and 12 - embodiments of saw blades; in fig. 13 is a section of YYY in FIG. 12, in FIG. 14 is a section d-d in FIG. 12. The circular saw blade contains in its peripheral cutting zone 1 thirty cutting teeth 2 evenly distributed around the roundness, each of which is provided with a plate 3 of hard alloy. To the cutting zone 1 along the radius there is an adjoining carrier disk 4, containing a central hole 5 for mounting on the drive shaft (it is not shown). circular saw blades. The carrier disk 4 may have an axially measured thickness of 0.4 of the section width of the carbide plates 3, which form the cutting width b. The saw blade on its surface has uniformly circumferential waves 7–9 and additional waves 10–12 and 13–15, which are located coaxially with the main 7–9 in the radial direction, with -. than the distance between the waves increases in the direction from the central part of the blade to the periphery due to the fact that the wave width in the circumferential direction is 22.5 and lies in the range 15-30 2 Waves alternately go to the sides of the saw blade, for example 7 and 9, 10 and 12, 13 and 15 lie on one side of the side, while 8, 11 and 14 lie on the opposite side. Between the waves in the circumferential and radial directions there are flat sections, respectively 16 and 17, and the distance between adjacent waves in the circumferential direction (Fig. 3 and 11) is less than the width of one of these waves, and the shape of the waves can be triangular, oval, trapezoid, or other (Fig. 3 11 and 12). The height of the waves does not reach the surface of the cut by the value of f and may be 0.4-0.6 mm. Due to the compacted structure of the waves on the carrier disk 4, the magnitude and position of the radial and tangential stresses can be selected by means of the shape, size and position of the waves. In addition, the waves contribute to the cooling of the carrier disk, as it rotates the surrounding air, and reduces friction against the walls of the kerf due to the rounding of the 18 wave surfaces. According to FIG. 3, the carrier disc has uniformly distributed sector-shaped waves 19 and 20 or 21 and 22 which alternately protrude from both sides of the saw blade. The waves can also be oblong fori and extend in the radial direction, and their length can be both the same and different, a symmetrical arrangement of the waves 24 with respect to the elongated wave 23 is preferred, while the waves of the same length are equally distributed on both sides of the carrier disk 4. FIG. Figures 6-10 show cross sections of saw blades in variants of their implementation. Waves 25 - 29 in the radial direction alternately act on one or the other side of the saw head (Fig. 6). Between the three waves 30-32 adjacent to the flange zone 33, and the indicated waves 25-29 lies the undeformed intermediate annular portion 34. In contrast to this (Fig. 7), waves 37 are provided between the flange zone 35 and the marginal zone 36. FIG. The 8 carrier disc has radial direction near its flange zone 38 Two waves 39 and 40 passing into a radially wider wave 41, adjacent to waves 42 and 43, lying on wave 44, which goes to the other side of the carrier disc compared to with wave 41. Two waves 45 and 46 are radially outside, passing into wave 47, which, in turn, is adjacent to the non-deformed flat edge zone 48. These waves are also distributed evenly throughout the carrier. disk. According to FIG. 9, a pair of waves 50 and 51 adjoin the outer edge zone 49. with a large curvature. Waves 52-56 lying from these waves closer to the center of the carrier disk are blunt on the outside and have a greater width than waves 50 and 51. Wave 57 (Fig. 10) prfFs to the outer edge zone 58 and reaches the lateral limit 59 of the cutting eub 2 and then passes into wave 60, which reaches the other lateral constraint 61 and, in turn, passes into wave 62. Next, the deformed waves 63 and 64 protrude beyond the lateral constraints 59, i.e. their width is greater than the width of the cut 6. The deformed waves 63 and 64 additionally increase the rigidity of the carrier disk. FIG. Figure 11 shows the layout of the waves on the carrier disc. Waves can extend in both radial and circumferential directions. In addition, they can be distributed on the host disk equally or in groups. FIG. 12 shows another embodiment, in the upper half lying on /: one side of the carrier disk waves 65 and 66 and lying on the back side of the waves 67 and 68 are located at an angle to the radius of the saw blade. At the same time, waves 65 and 66 are longer than waves 67 and 68, and reach up to 69 eons of cutting. The upper right zone shows a wave 70 of a triangular shape, lying in the edge zone and with its rounded ring directed radially inward. Waves 71 and 72 (Fig. 12) reach the cutting zone 69 and can be of any shape and be located symmetrically, as well as reach the central hole 5. I On the supporting disk 4 (top of Fig. 13) are fixed outside the middle plate 3 hard alloy, namely to the right of the mid-plane of the BB. In the lower half of the plate 3. are fixed rimetrically to this plane. FIG. 14, the carrier disc lies outside the middle of the plates 3. Such asymmetric execution is obtained, in particular, when the waves in the carrier disc are also located asymmetrically to the mid-plane E-E. This achieves the fact that
    This tooth 2 is located either to the left or to the right of the middle plane EE at wave 70,
    If waves 65-68 lie in the zone of the central hole 5 and the overhang by the clamping flange 73, then the rigidity of the saw blade becomes even greater. In addition, the hollow back sides of the WAVE and / or the center of the carrier disk lying between the waves can be rigs.
    filled, for example, with plastic applied as a coating.
    The proposed embodiment of the saw increases the reliability of the design, contributes to a good heat sink, reduces friction against the walls of the cutting and increases the rigidity of the saw blade, which has a positive effect on the quality of sawing. qjue B (rig 7
