Description
Technical field
The utility model relates to a kind of instrument that is used for materials such as cutting stone material, concrete, refers in particular to a kind of diamond saw blade of dried cut.
Background technology
Diamond saw blade has superior cutting ability and polishing machine, be widely used in industries such as processing of stone, building, decoration, radiating effect is poor but we know saw blades for dry cutting, the substrate temperature height, yielding, the diamond saw blades for dry cutting can produce very big noise in sawing process, be detrimental to health.In order to solve noise problem, Chinese patent 200720102139.2 and 200720103052.7 just proposes a kind of noise reduction diamond disc, it be evenly produce colored type at the matrix periphery or steelyard hook type narrow slit, but the erasure effect of simple flower shape seam or steelyard hook groove part is good unlike common saw blade in the practical application.A kind of novel diamond disc was also once disclosed in order to solve noise problem Chinese patent 200520145567.4, it comprises saw blade, silica gel two parts, saw blade is made up of matrix and cutter head, cutter head is mixed after Thermocompressed sintering and forming by diamond particles and metal dust, matrix is through the machining aftershaping, matrix and cutter head sintering or weld together.Cut 2-15 noise reduction seam on the matrix, silica gel is coated in the noise reduction seam uniformly.But this technology does not play best effect for the saw blade sound deadening.
The utility model content
The utility model technical issues that need to address provide a kind of defective and deficiency that can overcome prior art, and a kind of low noise sintered diamond saw blade is provided.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The dried cut silent saw blade of a kind of sintered diamond, it comprises cutter head, matrix, and cutter head sintering or be welded on the circumferential edges of matrix all has the mouth of a river on the matrix between per two cutter heads, also have the noise reduction groove on the matrix of bottom, the mouth of a river, the noise reduction groove is the whirlpool structure; There is the noise reduction seam of the slyness of some circumferential distributions at the middle part of matrix.
The further concrete structure of noise reduction of the present utility model seam is: the noise reduction seam be shaped as the wherein a kind of of S shape smooth curve, two S shape smooth curve, M shape smooth curve or irregular smooth curve, also can be that the mixing of several shapes is used; The two ends of noise reduction seam are provided with stop hole.
Further improvement of the utility model is: be filled with damping material in the noise reduction seam.Damping material comprises that damping material can also be a high damping alloy, as copper-zinc-aluminum series alloy, manganese-copper series alloy as epoxy resin, butyl rubber, polyurethane etc.
Further improvement of the utility model is: adjacent noise reduction seam is staggeredly arranged, and leaves one section safe distance between their head and the tail.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
During work, the scroll noise reduction groove of the mouth of a river and bottom thereof can make by saw blade and rotate a part in the air stream of drive at a high speed, flows away from the noise reduction groove, does not participate in rotation at a high speed, and weakens in " whirlpool ", thereby reduced the Rotation Noise of air.The noise reduction seam of the S shape that matrix middle part is along the circumferential direction arranged, two S shape, M shape, the vibration that has produced when having interrupted the saw blade cutting and the propagation of friction noise, added damping material after, can also absorb vibrational energy, reduce vibration noise and impact noise.The noise reduction seam of slick and sly S shape, two S shape, M shape or irregular curve shape goes for different sizes or saw blades different rotating speeds, that cutting force is different.Article two, the noise reduction seam staggers mutually, leaves safe distance from beginning to end, can guarantee the intensity of saw bit matrix.
