(2) Conventional technology: At present, when a circular saw is used, the outer peripheral portion near the cutting edge expands due to the cutting heat generated during cutting, and the outer peripheral portion near the rotary shaft is compared to the outer peripheral portion. And not heated so much. Due to the temperature difference from the center to the outer circumference, the entire saw is distorted, causing left and right runout during cutting, which causes severe damage to the cutting edge, resulting in contact between the cutting surface and the saw blade side surface. As a result, the temperature becomes high, and a metal saw, which generates a lot of heat, emits a high noise and cannot be cut. The present invention is intended to overcome this reality, and as a solution to this phenomenon, the present invention is to keep the central axis of the blade body (desk) of the saw blade and the central portion of the outer peripheral portion of the cutting blade around the entire circumference. The so-called waist removal work was performed, which was to knock it out and extend it around the center. Since this work requires a high level of skill, it is regarded as a difficult field of machining, and the number of saw blades that perform this machining is small. Some of the current metal saws prohibit continuous cutting for a long time as a breakthrough measure.

(3) Problem to be Solved by the Invention: According to the present invention, the outer peripheral portion of the saw blade is deformed and distorted due to the heat generated during the cutting operation of the saw blade body, resulting in uncutability and cutting. Since the blade is twisted and the cutting edge portion of the desk is softened by heat due to the high heat, the entire cutting edge tip is significantly damaged and the service life thereof is shortened. According to the present invention, by arranging an appropriate number of linear cutouts in which a weak point of such a saw is thinly bent and refracted on a saw blade desk, lateral deflection at the time of cutting the saw blade is prevented, and the service life of the cutting blade tip is increased. It is a thing.

(4) Means for solving the problem: FIGS. 4 and 5 show two kinds of slits installed in the blade body from the base of the cutting blade portion of the tip, but both of them are cut out in a thin straight line. It is a gap (slit). Since these slits are currently equipped with cuts on the desk, the blade body may break from the slits when excessive cutting force is applied, or the cutting blades before and after the slits are installed. Was sometimes broken. Therefore, fewer and fewer saw blades are now provided with these slits. In the present invention, the slits are bent or curved in order to prevent occurrence of weak points such as distortion and runout due to a temperature difference from the center to the outer peripheral portion of these saw blades, and the desk (1) and the cutting edge portion (3). By changing the action direction of the cutting force acting on), and mitigating this, it is possible to prevent the drawbacks of the slit installed in the conventional saw blade. 1 and 2 show two basic types of slits of a soft metal saw blade. In both cases, the action part is formed by a bent slit in the center part where the temperature is relatively low, so that the cutting force does not act directly on the action part of the slit (the end of the slit with a circular hole) like a conventional saw blade. Absent. Further, the strain due to thermal expansion is longer than that of the straight slit and the direction thereof is also parallel to the outer peripheral portion, so that the strain of the entire saw desk is absorbed and relaxed. Although (1) in FIG. 3 shows a curved slit installed on a saw blade for metal or synthetic resin for high-speed cutting, in this field, the temperature at the center of the desk tends to be higher than that near the cutting edge. Therefore, the temperature difference between the outer peripheral portion and the central portion is small. Therefore, it is better to install four slits like this. (II) and (III) in FIG. 3 are for synthetic resin or woodworking, and are suitable for a large-diameter saw blade with a thick desk. These have a large contact surface between the cutting surface and both side surfaces of the saw blade, so that the saw blade that causes lateral vibration burns the cut surface due to contact heat. (II) and (III) shown in the figure not only prevent lateral runout, but also have a slit curve up to the center of the desk, and since it is large, it is necessary to cut while following the cutting surface of the cutting blade. The contact heat generated on the side surface of the saw blade is small. FIG. 6 shows a curved slit installed in a small-diameter woodworking saw and a saw blade for soft metal. FIG. 7 shows curved slits installed on a small-diameter metal saw blade. FIGS. 8, (1), (2), and (3) show curved slits installed on a saw blade used for hard metal, high-viscosity metal (stainless steel, etc.), synthetic resin with high hardness, etc., respectively. Providing a slit around the base of the cutting edge of the saw for difficult-to-cut materials is very dangerous because it causes damage to the cutting edge before and after the slit. FIG. 8 shows a curved slit (1) installed on a saw for cutting difficult-to-cut materials such as stainless steel,
Although three types of (2) and (3) are illustrated, there are bent points (5) and (5 ') surrounded by curved slits, and there are a front bent point (5) and a rear point (5). ') And are alternately formed and retained, the disk is cut at the time when the cutting edge tips on the cutting action starting lines (C) to (C') in FIGS. 8 (2) and (3) act. The convex portions (5) and (5 ') at the tips formed by being surrounded by the curved slits inevitably enter the inside of the cutting surface, and have the greatest effect at the start of the cutting. The vibration due to the cutting load is prevented and controlled. The conventional slits shown in FIGS. 4 and 5 are straight slits (4) cut in the front part of the cutting edge part of the cutting edge tip (2) at the time when the maximum cutting load is applied during cutting. Since it is rare, the wobbling of the cutting edge also becomes large, and the result leads to damage or destruction of the cutting edge part or the cutting edge tip. The curved slits (4) of the present invention form curved peaks (5) and (5 ′), and the expansion and contraction due to heat during cutting are the slit width of the slit (4) and the curved slits that are bent longer than straight slits. Due to the expansion and contraction of the disk, the distortion of the desk due to heat is corrected and the lateral vibration at the time of cutting and the cutting noise due to the contact between the saw blade desk and the cutting surface can be significantly reduced. The advantage of the curved slits (4) is that the angle of refraction, the curvature of the arc, the length, the cutout width, the position and the number of installations can be appropriately selected according to the hardness and viscosity of the object to be cut. It is possible to make a saw blade desk that can handle objects. The cutout width of the slit (4) is appropriately 1 mm to 5 m, and the number of the slits to be installed is determined by the thickness of the saw blade desk and the number of rotations used.
And the material of the material to be cut is the main factor in the decision.

(5) Action: As described above, the curved slits installed on the saw blade desk are installed from the base of the cutting edge part (3) for cutting soft materials, and only inside the desk for cutting high hardness and viscosity materials. By disposing an appropriate number in [(1), (2), (3) in FIG. 8], it is possible to prevent the blade desk from being distorted by heat during cutting. There is no proper cutting work. In addition, since it is possible to omit the work of removing the waist, which requires high technology in terms of processing, the manufacturing cost of the product is low, and mass production is easy.

Since the tip of the clam of the copper plate saw blade is severely damaged, this was conventionally done by waist punching, which required advanced technology, but it was a very laborious process. According to the present invention, it is possible to easily and reliably prevent the distortion of the saw blade (1) due to the cutting heat and the frictional heat caused by the contact by installing curved slits. That's a big step forward.
