Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a schematic view of a multi-noise reduction diamond-tipped saw blade according to an embodiment of the present disclosure. As shown in the drawing, a multi-noise reduction diamond-tipped saw blade comprises an alloy substrate 10 having a central through hole 11; the sawtooth parts 20 are arranged on the edge of the alloy substrate 10 in a surrounding mode, the sawtooth parts 20 are spaced through the U-shaped grooves 30, and one end, facing the cutting direction, of each sawtooth part is provided with a strip-shaped notch 40; a protruding blade head portion 50 welded to the bar-shaped notch 40; the circumference array is arranged in 4 silencing openings 60 of the alloy substrate 10, and the silencing openings 60 are communicated with the bottom of the U-shaped groove 30; and a silencing line 70 circumferentially arrayed on the surface of the alloy substrate 10 and intersecting with the silencing port 60; the silencing port 60 comprises a first straight notch 61 communicated with the bottom of the center of the U-shaped groove 30 and a second round notch 62 communicated with the bottom of the first straight notch 61.

In one embodiment of the present invention, the alloy substrate 10 has a central through hole 11 for easy installation, and is formed in a disc shape and made of a high strength and high toughness hard alloy. The sawtooth part 20 is arranged on the edge of the alloy substrate 10 in a surrounding mode, and the sawtooth part is spaced from the alloy substrate 10 through the U-shaped groove 30, so that the chip removal effect is enhanced. One end of the sawtooth part 20 is provided with an inwards concave strip-shaped notch 40 for welding a diamond cutter head part 50, so that the cutting effect is enhanced. In addition, 4 silencing openings 60 communicated with the U-shaped groove 30 are arrayed in the circumferential direction of the alloy substrate 10, each silencing opening 60 is composed of a first straight notch 61 and a second straight notch 62, the gap of the first straight notch is small, vibration on two sides is cut and reduced during cutting, noise is reduced, the second straight notches 62 with large sizes are connected in a radian mode, toughness is enhanced, the durability during cutting is improved, and the alloy substrate is convenient and practical.
