Problems solved by technology

Diamond tools will produce a lot of noise during dry cutting, and construction workers will be exposed to high-noise pollution for a long time, which will seriously damage their physical and mental health.
In the prior art, in order to solve the problem of high noise, noise reduction slots or / and noise reduction holes are usually cut or processed on the metal substrate, but if the design is not proper, not only the noise reduction effect is not obvious, but also may cause the saw blade The strength of the matrix is ​​significantly reduced

Embodiment 1

[0019] The low-noise diamond saw blade of the present embodiment comprises a circular steel substrate and 16 diamond cutter heads formed at the end of the circular steel substrate. Flutes. Four first sound-absorbing grooves are evenly distributed at a first distance from the center of the circular base body, and four second sound-absorbing grooves are evenly distributed at a second distance from the center of the circular base body; the second distance is twice the first distance, and the length of the second silencer is twice the length of the first silencer. The shapes of the first and second sound-absorbing grooves include straight lines parallel to each other and smooth curves between adjacent straight lines, and both ends of the first and second sound-absorbing grooves are provided with end blind holes. The cross-sections of the first and second sound-absorbing grooves are both semicircular, and the maximum width thereof is 0.5mm. The first and second sound-absorbing gro...

Abstract

The invention relates to a low-noise diamond saw blade and belongs to the technical field of diamond cutting tools. The low-noise diamond saw blade comprises a circular substrate and a plurality of diamond cutting bits formed at the end of the circular substrate. Scrap discharge grooves extending into the circular substrate are formed between the adjacent diamond cutting bits. A plurality of first silencing grooves are evenly distributed in the positions away from the center of the circular substrate by a first distance, and a plurality of second silencing grooves are evenly distributed in the positions away from the center of the circular substrate by a second distance. The second distance is larger than the first distance, and the second silencing grooves are longer than the first silencing grooves. According to the low-noise diamond saw blade, the noise index can be lowered by 8-10 dB under the same construction condition on the premise that the strength of the substrate is ensured, and the improvement on the comfort of the working environment is facilitated.

Description

technical field [0001] The invention relates to the technical field of diamond cutting tools, more specifically, the invention relates to a low-noise diamond saw blade used for cutting and trimming marble, granite, microcrystalline stone and other materials. Background technique [0002] In today's market, diamond cutting tools have been widely used in the cutting and repairing of hard materials such as marble, granite, microcrystalline stone, jewelry and jade; continuously improving cutting efficiency, reducing material loss, and improving the service life of diamond tools are the common pursuit of the market direction. Diamond tools will generate a lot of noise during the dry cutting process, and construction workers will be exposed to high-noise pollution for a long time, which will seriously damage their physical and mental health. In the prior art, in order to solve the problem of high noise, noise reduction slots or / and noise reduction holes are usually cut or process...
