Description

Technical Field

[0001] The utility model relates to the technical field of hard material cutting tools, in particular to a K-wave diamond saw blade. Background Art

[0002] Diamond saw blades are commonly used cutting tools for cutting hard materials such as concrete, stone, and ceramics. They are mainly composed of a disc-shaped base with a flange and a cutter head that is sintered to the outer edge of the base by hot pressing. The cutter head is made of a base material such as metal mixed with diamond particles. The cutter head performs a cutting function during use, and the diamond rubs in the cutter head to cut the object being processed.

[0003] Current diamond saw blades mainly rely on improvements to the blade body or the grade of diamond particles to improve cutting sharpness. The disadvantages are increased costs or poor control of the production process. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and provide a K-wave diamond saw blade, which improves sharpness by arranging a cutting edge of a specific shape and a running angle on the blade head.

[0005] The technical solution of this utility model is described in detail as follows:

[0006] A K-wave diamond saw blade comprises a base body (1) with a flange and a cutter head (2) having a concentric center. The cutter head (2) is provided with a cutting edge (3) protruding from the surface. The bending angle (a) of the cutting edge (3) is 108 degrees.

[0007] Optionally or preferably, the surface of the cutter head is further provided with a "K"-shaped chip groove (4) protruding from the surface, the chip groove (4) including an outer V-angle (41) opening toward the outer edge of the cutter head (2) and an inner V-angle (42) opening toward the center of the circle, the outer V-angle (41) including a first outer side wall (411), the inner V-angle (42) including a second outer side wall (421), and the angle between the first outer side wall (411) and the second outer side wall (421) is 108 degrees; the cutting edge (3) is arranged parallel to the first outer side wall (411) and the second outer side wall (421).

[0008] Optionally or preferably, the cutting edge (3) and the chip groove (4) are multiple and evenly spaced on the cutter head (2).

[0009] Optionally or preferably, the cutter head (2) is further provided with a heat-resistance groove (5) extending linearly and obliquely from the outer edge of the cutter head (2) toward the inner edge, and the heat-resistance groove (5) passes through the upper and lower surfaces of the cutter head.

[0010] Optionally or preferably, the angle between the end of the heat-resistance groove (5) and the saw blade diameter (D) is 21 degrees.

[0011] Optionally or preferably, the number of the heat-resistance grooves (5) is 4-8 and is evenly distributed on the cutter head (2). The number of the heat-resistance grooves (5) can be adjusted according to the size of the saw blade. For example, if the saw blade has a larger diameter, more heat-resistance grooves (5) can be provided. If the saw blade has a smaller diameter, fewer heat-resistance grooves (5) can be provided. Generally, 4-8 heat-resistance grooves are preferred.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This new design features circumferentially arranged 108-degree curved cutting edges on the blade surface, utilizing the 108-degree angle to enhance cutting sharpness and speed. A "K"-shaped chip flute with internal and external V-angle grooves further facilitates chip removal. Heat-blocking grooves divide the blade into multiple, discrete areas, effectively blocking heat. The 21-degree angle provides both robustness and heat resistance, minimizing the risk of tooth loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the present application, the present application will be clearly and completely described below in conjunction with the embodiments and drawings. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] Example 1

[0021] Please refer to Figure 1 and Figure 2It is a K-wave diamond saw blade, comprising a base 1 with a flange and a cutter head 2. The surface of the cutter head 2 is provided with multiple cutting edges 3 protruding from the surface and a "K"-shaped chip groove 4. The multiple cutting edges 3 and chip grooves 4 are evenly spaced around the cutter head.

[0022] Please refer to Figure 2 The chip groove 4 includes an outer V-angle 41 opening toward the outer edge of the cutter head 2 and an inner V-angle 42 opening toward the center of the circle. The outer and inner grooves 412 and 422 formed by the opening parts of the outer V-angle 41 and the inner V-angle 42 can effectively discharge the debris generated during cutting. The outer V-angle 41 includes a first outer side wall 411, and the inner V-angle 42 includes a second outer side wall 421. The angle between the first outer side wall 411 and the second outer side wall 421 is 108 degrees. The cutting edge 3 is arranged parallel to the first outer side wall 411 and the second outer side wall 421, and the 108-degree bent groove formed therebetween is also conducive to chip removal. The bending angle a of the cutting edge 3 is 108 degrees. This operating angle can better increase the cutting speed, thereby improving the cutting sharpness of the saw blade.

[0023] Please refer to Figure 3 The blade head 2 also features multiple heat-resistant grooves 4 extending linearly and obliquely from the outer edge of the blade head 2 toward the inner edge. These grooves 4 penetrate the upper and lower surfaces of the blade head 2 and are typically machined using laser line cutting. The angle c at the intersection of the end of the heat-resistant groove 4 near the center and the saw blade diameter D is 21 degrees, providing both heat resistance and durability, reducing the risk of continuous burning in adjacent areas of the blade head on either side of the grooves during saw blade rotation.

[0024] The K-wave diamond saw blade of the utility model improves the cutting sharpness by improving the cutting edge of the cutter head and the structural style and angle of the chip groove. In addition, the heat dissipation effect is improved by the design of the inclined linear heat-resisting groove.

It should be noted that any obvious modifications, equivalent substitutions, or other improvements made by a person skilled in the art without departing from the inventive concept should be included within the scope of protection of the present invention.
