A low-noise diamond saw blade

Abstract

The invention discloses a low-noise diamond saw blade. The low-noise diamond saw blade comprises a circular base plate, a liquid gallium alloy as well as diamond bit pieces and magnet combinations which are evenly welded on the outer side of the circular base plate; a circular staggered eccentric flow-guiding channel is formed inside the circular base plate; a fixing sleeve is symmetrically weldedin the center of the side wall of the circular base plate in a penetrating manner; the circular staggered eccentric flow-guiding channel comprises a circular channel I and a circular channel II; thin-wall arc-shaped plates are evenly welded on the inner side wall of the circular channel I and the inner side wall of the circular channel II; the circular channel I and the circular channel II are filled with the liquid gallium alloy; and the liquid gallium alloy flows in a communicating manner. According to the saw blade, the thin-wall arc-shaped plates are evenly distributed by the aid of the circular staggered eccentric flow-guiding channel and can absorb shocks produced during cutting of the saw blade, during rotation of the circular base plate, spaces among the thin-wall arc-shaped plates are filled with the liquid gallium alloy, the liquid gallium alloy has the excellent shock-absorbing function, and then the cutting noise can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of diamond saw blades, in particular to a low-noise diamond saw blade. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. The diamond saw blade is mainly composed of two parts; the substrate and the cutter head; the substrate is the main supporting part of the bonded cutter head; [0003] The diamond saw blade achieves the purpose of cutting through high-speed rotation and feed contact with the cut part and removes the material at the contact position; because the substrate adopts a thin sheet structure, there will be a large noise due to high-frequency vibration and cutting resistance during cutting, which is not necessary It is conducive to the safe production of the operator; at the same time, the load friction cutting will cause the entire saw blade to generat...

Problems solved by technology

[0003] The diamond saw blade achieves the purpose of cutting through high-speed rotation and feed contact with the cut part and removes the material at the contact position; because the substrate adopts a thin sheet structure, there will be a large noise due to high-frequency vibration and cutting resistance during cutting, which is not necessary It is conducive to the safe production of the operator; at the same time, the load friction cutting will cause the entire saw blade to generate a lot of heat, and the long-term overheating will cause the substrate to deform and reduce the service life; therefore, the present invention provides a low-noise diamond saw blade
