Abstract
The utility model relates to an amortization carbide saw blade, it includes circular saw blade body, the equipartition setting sword tooth on the circumference and set up the centre bore at circular saw blade body middle part outside the circular saw blade body the equipartition sets up a 4 -6 amortization seam on the circumference of circular saw blade body, and the amortization seam is continuous U -shaped, and adjacent U -shaped opening is opposite, and the width of amortization seam is 0.45 -0.55mm, sets up the amortization round hole respectively at the starting and destination point that rises of amortization seam, the utility model discloses the amortization is stitched, and the noise diminishes when the cutting, has reduced the noise, and the stress concentration when processing the amortization seam is eliminated simultaneously to the amortization round hole when reducing the noise, avoid the circular saw blade body to crack.
Description
Technical field
This utility model relates to a kind of noise reduction sintered carbide circular saw.
Background technology
Install at high-grade solid wood, wood-based plate and in the course of processing, it need to be cut, the saw blade high speed rotating when cutting, cause air draught disorderly, cause screaming of air-flow, produce great noise, make operator can not work in the environment that sound is relatively small；When cutting the metal material material such as angle bar, iron pipe, owing to saw blade rotating speed is high, saw blade expanded by heating rapidly in cutting process, cause cutting deviation, make saw blade cutting life shorten simultaneously, need to often change saw blade, improve production cost, and discarded saw blade is arbitrarily abandoned, and causes environmental pollution.
Utility model content
When technical problem to be solved in the utility model is to provide saw blade cutting, noise is little, the noise reduction sintered carbide circular saw of saw blade rapid heat dissipation.
This utility model adopts the following technical scheme that
This utility model includes circular saw blade body, the uniform cutter tooth being arranged on circular saw blade body excircle and is arranged on the centre bore in the middle part of circular saw blade body, uniform on the circumference of described circular saw blade body 4-6 silencing seams is set, described silencing seams is continuous print U-shaped, adjacent U-shaped opening is contrary, the width of described silencing seams is 0.45-0.55mm, and initiating terminal and end at described silencing seams are respectively provided with noise reduction circular hole.
This utility model good effect is as follows: this utility model is arranged on the silencing seams on saw blade circumference, and when cutting, noise diminishes, and reduces thermal stress when noise, expansion slot and inflation port can alleviate cutting, improves the service life of saw blade, save production cost；Noise reduction circular hole is while reducing noise, and stress when simultaneously eliminating processing silencing seams is concentrated, and avoids circular saw blade body to crack.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation；
Accompanying drawing 2 is this utility model silencing seams structural representation.
Detailed description of the invention
As shown in accompanying drawing 1,2, this utility model includes circular saw blade body 1, the uniform cutter tooth 7 being arranged on circular saw blade body 1 excircle and is arranged on the centre bore 2 in the middle part of circular saw blade body 1, uniform on the circumference of described circular saw blade body 1 4-6 silencing seams 3 is set, described silencing seams 3 is continuous print U-shaped, adjacent U-shaped opening is contrary, the width of described silencing seams 3 is 0.45-0.55mm, and initiating terminal and end at described silencing seams 3 are respectively provided with noise reduction circular hole 4.When silencing seams 3 can make cutting, noise diminishes, and reduces noise；Radially uniform on the circumference of described circular saw blade body 1 arranging expansion slot 5, arrange inflation port 6 at described expansion slot 5 end, the upper end of described expansion slot 5 is arranged on cutter tooth 7 lower end, and described silencing seams 3 is between adjacent expansion slot 5.Described expansion slot 5 and inflation port 6 can alleviate thermal stress during cutting, improve the service life of saw blade, save production cost；Noise reduction circular hole 4 is while reducing noise, it is possible to stress when simultaneously eliminating processing silencing seams 3 is concentrated, it is to avoid circular saw blade body cracks.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in previous embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model embodiment technical scheme.
