Saw blade is the general designation of the thin slice circular knives for cutting solid material, carries out high-speed cutting by High Rotation Speed.There is the problem that service life is short, cutting accuracy is low and production efficiency is on the low side in cast-cutting saw slice in the past, and larger kerf burr are produced in the process of cutting, need to increase and repeat recruitment, cause the waste of material, the consumption of the energy, thus processing cost is increased substantially.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of simple to operate, production efficiency is high, can effectively reduce kerf burr phenomenon and province material labour-saving aluminium alloy special saw blade.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of aluminium alloy special 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, described noise reduction expansion slot one end communicates with the excircle of described saw bit matrix, other end end is inlaid with fastener, described sawtooth is even numbers, sawtooth is provided with cutter, the anterior angle of described cutter is 8 degree, relief angle is 12 degree, described cutter is flat serrated knife tool and stepped tooth cutter, described flat serrated knife tool and stepped tooth cutter are spaced cross-distribution.
Further, described cutter noise reduction expansion slot has five, is evenly distributed on described saw bit matrix.
Further, the side rake angle of described flat serrated knife tool is 0 degree, and side relief angle is 1.5 degree.
Further, the tip inclination angle of described stepped tooth cutter is 45 degree, and centripetal angle, side is 0.8 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; Noise reduction expansion slot end is inlaid with fastener, prevents the saw blade when the aluminum alloy materials that cutting hardness is higher from producing vibration, adds the stability of sawing, improve cutting accuracy; Cutter adopts flat serrated knife tool and the distribution of stepped tooth cutter space crossings, is first cut, then carry out fine finishining by flat serrated knife tool during cutting by stepped tooth cutter; available protecting service life of touching the pillow; stopped the phenomenon that kerf is large, unedged, less repetition recruitment, improves production efficiency.

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 aluminium alloy special saw blade, comprises the saw bit matrix 1 that is provided with centre bore 5 and is arranged on saw bit matrix 1 cylindrical circumferentially some sawtooth 3.
Saw bit matrix 1 is also evenly distributed with five noise reduction expansion slots 2, one end of every bar noise reduction expansion slot 2 communicates with the excircle of saw bit matrix 1, and the end of the other end is inlaid with fastener 4.It is the noise and thermal deformation that produce that noise reduction expansion slot can reduce in sawing.When the aluminum alloy materials that saw blade cutting hardness is higher, saw blade can produce vibration, and saw bit matrix 1 is inlayed the vibration that fastener 4 can reduce saw blade effectively, thus reduces the generation of kerf, improves the precision of cutting.
Sawtooth 3 is even numbers, and sawtooth 3 is provided with cutter 6, cutter 6 is flat serrated knife tool 8 and stepped tooth cutter 7, and flat serrated knife tool 8 and stepped tooth cutter 7 are spaced cross-distribution.
Further, the anterior angle 9 of cutter 6 is 8 degree, and relief angle 10 is 12 degree; The side rake angle 11 of flat serrated knife tool 8 is 0 degree, and side relief angle 12 is 1.5 degree; The tip inclination angle 13 of stepped tooth cutter 7 is 45 degree, and centripetal angle 14, side is 0.8 degree.
As shown in Figure 2, anterior angle 9 is the angles before cutter between 91 and basal plane 92, and anterior angle 9 adopts less angle, is conducive to the intensity improving cutter head, both can improves the speed of cutting, also can improve cutting-tool's used life simultaneously.Relief angle 10 is the angles between cutter end face 101 and cut direction 102, and the design of relief angle low-angle effectively can prevent the cracked phenomenon of aluminium alloy.
As shown in Figure 3, the side rake angle 11 of flat serrated knife tool 8 is the angle between the main cutting edge 111 of flat serrated knife tool 8 and basal plane 92, and side relief angle 12 is the angle between the side 121 of flat serrated knife tool 8 and cut direction 102.Side relief angle 12 adopts low-angle to design, and can effectively reduce the frictional force produced when sawing, reduces the generation of heat.
As shown in Figure 4, the tip inclination angle 13 of stepped tooth cutter 7 is the angle between the top side face 131 of stepped tooth cutter 7 and basal plane 92, and centripetal angle 14, side is the angle between the side 141 of stepped tooth cutter 7 and cut direction 102, effectively can solve the problem of kerf.
When saw blade cuts, first cut away most of aluminum alloy materials by stepped tooth cutter 7, then carry out fine finishining by flat serrated knife tool 8, effectively protect the service life of cutter head.
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.
