Abstract
The utility model discloses a noise-reduction vibration-damping sintered diamond saw blade, comprising a basal body (2) which has a center hole connected with a tool main shaft and a cutter head (1) which is sintered on the basal body (2), and is characterized in that noise-reducer holes (3) which are distributed from small to large and from inside to outside along the radius direction are arranged on the basal body, the noise-reducer holes (3) are arranged on the basal body (2) which is arranged away from 1/3 radius of a saw blade to form the centrifugal curve type or straight line type from inside to outside, the diameter of the noise-reducer hole (3) increases from 4.5 mm to 6.5 mm from inside to outside, and the periphery of the center hole of the basal body (2) is provided with a boss (4). In the utility model, the impact vibration period of the saw blade is disturbed, which reduces the resonant probability in the process of cutting of the saw blade, reduces the vibration of the saw blade, cancels out or weakens the high-speed air flow caused by the rotation of the saw blade, reduces noises and thermal deformation, improves the bearing state of the saw blade, enhances the service life of the saw blade, and increases the processing quality.
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 disc.
Background technology
In the prior art, the instrument of cutting fragile material mostly adopts diamond saw blade, be on the edge of disc metallic matrix sintering, to contain adamantine cutter head, violent shake can appear in these saw blades saw blade in use, cause stone material to collapse the limit, also can make very big very harsh noise, and saw blade cutter head often occurs and collapse tooth, cause the service life of saw blade too short.For solving noise problem, Chinese patent 200720102139.2 discloses a kind of noise reduction diamond disc, comprises cutter head, and matrix, saw blade edge have colored shape joint-cutting.Be similarly the solution noise problem, Chinese patent 200720103052.7 discloses a kind of sector noise reduction diamond disc, comprises cutter head, matrix, cutter head is fan shape, and is symmetrical distribution with narrow slit on the matrix, matrix is annular, and the matrix periphery is evenly distributed with steelyard hook type narrow slit.Above-mentioned technology is in order to solve the noise reduction problem, between two cutter heads in the edge of saw blade, cut out colored shape seam or steelyard hook groove part exactly, such simple designs, might reduce the vibrations of cutter head part, but with between the cutter head of other form reeded structure is set and compares, spend the erasure effect of shape seam or steelyard hook groove part good merely unlike common saw blade.
The utility model content
The utility model technical issues that need to address provide and a kind ofly reduce cutting noise, improve stress, improve the saw blade of the cutting performance of saw blade.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of porous noise reduction vibration damping diamond sintering saw blade comprises matrix and cutter head, and the center of matrix is provided with the centre bore that is connected with tool spindle, and the cutter head sintering is on matrix.The matrix upper edge radial direction diameter bloop from small to large that distributing from inside to outside; The scope that bloop distributes is on the matrix beyond saw blade 1/3rd radiuses; Along with the increase of distance saw blade center radius, the diameter of bloop increases to 6.5mm by 4.5mm, and the diameter that is positioned at the bloop on the circumference of same radius of matrix is identical, and the bloop on the different circumference is arranged in centrifugal shaped form or linear pattern from inside to outside.
Further concrete structure of the present utility model is: be provided with boss around the centre bore of matrix.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The impact shock cycle that the utility model adopts the bloop of different sizes to upset saw blade has reduced the resonance probability in the saw blade cutting process, reduces the saw blade shake; The air stream of the high speed that the saw blade that bloop also can make high speed rotate causes is cancelled out each other or is weakened, thereby reduces noise and thermal deformation, improves the stress of saw blade, improves the service life of saw blade, improves crudy.The saw blade centre bore is the boss of setting on every side, has increased the intensity of saw blade, reduces vibrations and resonance.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
Embodiment 1
As shown in Figure 1, the sintered diamond saw blade of present embodiment comprises cutter head 1, matrix 2, and matrix 2 is a disc, and the center of matrix 2 is provided with the centre bore that is connected with tool spindle, is provided with boss 4 around the centre bore.Cutter head 1 sintering is on the edge of matrix 2.On the matrix 2 beyond 1/3rd radiuses at distance saw blade center, along the radial direction diameter bloop 3 from small to large that distributing from inside to outside, totally three layers of bloops 3, its diameter increases to Φ 6.5mm by Φ 4.5mm from inside to outside; Bloop on the matrix on the circumference of each same radius big or small identical, the adjacent bloop on the different circumference is arranged in centrifugal shaped form from inside to outside.
Present embodiment is with the difference of embodiment 1 as shown in Figure 2: matrix is the identical flat board of thickness, and boss is not set around the centre bore of saw blade.Bloop 3 is arranged in the linear pattern that certain angle is arranged with radial direction from inside to outside.
Present embodiment is with the difference of embodiment 2 as shown in Figure 3: bloop 3 be covered with beyond 1/3 radius of saw blade to cutter head with interior matrix 2 on, six circle bloops are arranged from inside to outside, the adjacent bloop on the adjacent circumferential is arranged in shaped form.
Claims (4)
1, a kind of noise reduction vibration damping sintered diamond saw blade, comprise the matrix (2), the cutter head (1) of sintering on matrix (2) that are provided with the centre bore that is connected with tool spindle, it is characterized in that: the matrix upper edge radial direction bloop (3) from small to large that distributing from inside to outside; Bloop (3) is distributed on 1/3rd radiuses matrix (2) in addition of saw blade.
