For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of deburring to saw saw blade, comprise the saw bit matrix that is provided with centre bore and be arranged on described saw bit matrix cylindrical circumferentially some sawtooth, it is characterized in that: described saw bit matrix is also provided with noise reduction expansion slot, louvre and locating hole, described noise reduction expansion slot one end communicates with the excircle of described saw bit matrix, the other end is hook-shaped, described louvre and described noise reduction expansion slot are apart from one another by cross-distribution, described locating hole is distributed in around described centre bore, described sawtooth is even numbers, sawtooth is provided with cutter, the anterior angle of described cutter is 15 degree, relief angle is 15 degree.
Further, described cutter noise reduction expansion slot has five, is evenly distributed on described saw bit matrix.
Further, described louvre has five, is evenly distributed on described saw bit matrix.
Further, the side rake angle of described cutter is 10 degree, and side relief angle is 2.5 degree.
Further, centripetal angle, the side of described cutter is 0.5 degree.
The advantage that the utility model has and beneficial effect are: be provided with noise reduction expansion slot, effectively can reduce the noise and thermal deformation that produce when sawing; Be provided with louvre, effectively can improve heat sinking function, accelerate the discharge of heat, effectively prevent the thermal deformation of saw bit matrix; Be provided with locating hole, contribute to increasing sawing dynamics, prevent the phenomenon thrown switch when sawing; Cutter is provided with anterior angle, the cutting speed of saw blade is increased substantially, effectively boost productivity, cutter is provided with relief angle and side relief angle, the frictional force produced when can reduce sawing, reduces the generation of heat, cutter is provided with centripetal angle, side, effectively can stop large, the unedged phenomenon of kerf, reduce and repeat recruitment, enhance productivity.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-Figure 4, the utility model provides a kind of deburring to saw saw blade, comprises the saw bit matrix 1 that is provided with centre bore 4 and is arranged on saw bit matrix 1 cylindrical circumferentially some sawtooth 2.
Saw bit matrix 1 is also provided with noise reduction expansion slot 5, louvre 6 and locating hole 7.Noise reduction expansion slot 5 has five, is evenly distributed on saw bit matrix 1, and one end of every bar noise reduction expansion slot 5 communicates with the excircle of saw bit matrix 1, and the end of the other end is hook-shaped.It is the noise and thermal deformation that produce that noise reduction expansion slot 5 can reduce in sawing.Saw bit matrix 1 is evenly provided with five louvres 6, louvre 6 and the spaced cross-distribution of noise reduction expansion slot 5.The design of louvre 6 improves heat sinking function more effectively, makes heat dissipation more quick, effectively prevents the generation of saw bit matrix 1 thermal deformation.Locating hole 7 has multiple, and not of uniform size, is distributed in centre bore 4 around.Saw bit matrix 1 arranges locating hole 7 and can increase sawing dynamics, prevent the phenomenon thrown switch when sawing.
Sawtooth 2 is even numbers, sawtooth 2 is provided with cutter 3.The anterior angle 8 of cutter 3 is 15 degree, and relief angle 9 is 15 degree, and side rake angle 10 is 10 degree, and side relief angle 11 is 2.5 degree, and centripetal angle 12, side is 0.5 degree.
As shown in Figure 2, anterior angle 8 is the angle before cutter 3 between 31 and basal plane 32, and anterior angle 8 can make the cutting speed of saw blade increase substantially, and effectively enhances productivity.Relief angle 9 is the angle between the end face 33 of cutter 3 and cut direction 34, and relief angle 9 can reduce frictional force during sawing, reduces the generation of heat.
As shown in Figure 3, the side rake angle 10 of cutter 3 is the angle between the main cutting edge 101 of cutter 3 and basal plane 32, and the design of side rake angle can increase the sharpness of sawing, produces the phenomenon of burr when solving sawing.Side relief angle 11 is the angle between the limit, top side 111 of cutter 3 and cut direction 34.Side relief angle 11 can effectively reduce the frictional force produced when sawing, reduces the generation of heat.
As shown in Figure 4, the centripetal angle 12, side of cutter 3 is the angle between the side 121 of cutter 3 and cut direction 34, effectively can solve the problem of kerf.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
