There is sawtooth, multiple expansion slots are provided with the saw bit matrix, for the expansion slot between adjacent two sawtooth, each expansion slot is equal
Extend from saw bit matrix outer circumference surface in the middle part of saw bit matrix, each expansion slot close to one end of saw bit matrix be provided with it is swollen
The receiving hole that swollen groove communicates, the aperture of the receiving hole are more than the width of expansion slot, copper tack are provided with the receiving hole.
In a kind of above-mentioned noise-proofing saw blade, the appearance for accommodating chip is provided between the sawtooth of arbitrary neighborhood two and is considered to be worth doing
Groove, the expansion slot are located in chip pocket and extended from chip pocket bottom to saw bit matrix middle part.
In a kind of above-mentioned noise-proofing saw blade, the blocking part for propping up the sawtooth, institute are provided with the rear of each sawtooth
Blocking part is stated from the bottom of sawtooth to its top extension and at the top of sawtooth.
In a kind of above-mentioned noise-proofing saw blade, several noise reduction heat-sink units are provided with the saw bit matrix, are each disappeared
Sound unit is included in the silencing groove with any trend and arbitrary shape formed on saw bit matrix by laser cutting, disappears each
The both ends of sound groove are respectively arranged with heat emission hole, and the heat emission hole communicates with silencing groove.
Compared with prior art, the utility model has the advantages that：
In the utility model, expansion slot is set on saw bit matrix so that saw bit matrix and noise caused by windage
Inflated groove is absorbed, and can be increased saw blade damped coefficient in thermal expansion trench bottom installation copper tack, be reduced self-excitation resonance, can eliminate
Saw blade caused noise in the range of every speed so that saw blade cutting is more steady, so as to eliminate the noise of working environment,
Noise is prevented to harmful effect caused by staff.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Shown in Fig. 1, a kind of noise-proofing saw blade of the utility model, including saw bit matrix 10, the middle part of saw bit matrix 10 are set
The centre bore 20 for fixing saw bit matrix 10 is equipped with, sawtooth 30, institute are evenly arranged with the outer circumference of saw bit matrix 10
State and multiple expansion slots 40 are provided with saw bit matrix 10, the expansion slot 40 is between adjacent two sawtooth 30, each expansion slot 40
Extend by the outer circumference surface of saw bit matrix 10 to the middle part of saw bit matrix 10, in each expansion slot 40 close to one end of saw bit matrix 10
The receiving hole 41 communicated with expansion slot 40 is provided with, the aperture of the receiving hole 41 is more than the width of expansion slot 40, the receiving
Copper tack 42 is installed in hole 41.
The utility model uses said structure, increases saw blade damped coefficient, reduces self-excitation resonance, can eliminate saw blade each
Caused noise in the range of speeds so that saw blade cutting is more steady, so as to eliminate the noise of working environment.
On the basis of said structure, the utility model has made further improvement and refinement to it.
As shown in Figure 1 and Figure 2, the chip pocket 50 for accommodating chip is provided between the sawtooth 30 of arbitrary neighborhood two, it is described
Expansion slot 40 is located in chip pocket 50 and extended from the bottom of chip pocket 50 to the middle part of saw bit matrix 10.
The setting of the chip pocket 50 so that chip caused by cutting product can be entered in chip pocket 50, avoid chip
Cutting around buckle for sawtooth 30 is deposited in, prevents chip from influenceing cutting of the sawtooth 30 to product, effectively raises cutting for product
Cut quality.
As shown in Figure 1 and Figure 2, the blocking part 60 for propping up the sawtooth 30 is provided with the rear of each sawtooth 30, it is described to support
