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

[0020] The sound-absorbing 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-absorbi...

Embodiment 2

[0022] The sound-absorbing 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 U-shaped, and their maximum width is 0.5mm, and the first and second sound-absorbing gro...

Embodiment 3

[0029] In this embodiment, 35% of the diamonds used have a particle size of 35 / 40, 40% of 40 / 45, and 25% of 45 / 50. Take 2.5kg of copper powder, 5.75kg of iron, 0.5kg of nickel, 0.7kg of cobalt, 0.4kg of tin, and 0.15kg of ferrophosphorus, put them into the mixing tank and mix for 30 minutes, add 0.06kg of liquid paraffin and 0.23kg of diamond, continue After mixing the materials for 4 hours, pour the powder into the mold for cold pressing and sintering. The hot pressing sintering temperature is 750°C and the pressure is 350kg / cm 2 , holding time is 180 seconds. Then use the grinding wheel and abrasive belt to grind the cutter head, put the cutter head and the substrate together on the corresponding substrate position according to the drawing requirements, adjust the light spot of the laser welding machine to the appropriate position between the cutter head and the substrate, and start the laser welding machine to weld, so that The cutter head and the substrate are welded toge...

Abstract

The invention relates to a noise reducing diamond saw blade, and belongs to the technical field of diamond cutters. The noise reducing diamond saw blade comprises a circular matrix and a plurality of diamond tool bits formed at the end parts of the circular matrix. A chip groove extending into the circular matrix is formed between every two adjacent diamond tool bits. A plurality of first noise reducing grooves are uniformly distributed in parts, which are first distances from the center of the circular matrix. A plurality of second noise reducing grooves are uniformly distributed in parts, which are second distances from the center of the circular matrix. The second distances are greater than the first distances. The second noise reducing grooves are longer than the first noise reducing grooves. On the premise of ensuring the strength of the matrix, the noise index is reduced by 8-10 dB in construction under the same condition, so that the comfort degree of the operating environment is beneficial for being improved.

Description

technical field [0001] The invention relates to the technical field of diamond cutting tools, more specifically, the invention relates to a sound-absorbing 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 p...
