Abstract
The utility model discloses a fall little anterior angle diamond saw blade of terraced tooth, including saw bit base member (1), a plurality of blade (2) and a plurality of sawtooth (3), saw bit base member (1) is circular, sawtooth (3) even distribution is on the circumference of saw bit base member (1), be equipped with the mounting groove that is used for installing blade (2) on sawtooth (3), install in the mounting groove blade (2), blade (2) are including substrate (21) and diamond layer (22), substrate (21) set up between sawtooth (3) and diamond layer (22), the anterior angle of blade (2) is 4, the rake face is trapezoidal, the directional outside of trapezoidal upper base. The beneficial effects of the utility model are that: this saw bit is used for saw cutting paddle -tumble in advance, can effectively prevent to explode the limit to it has hardness height, long service life, saw cuts advantages such as finish is good.
Description
Technical field
The utility model relates to saw blade, particularly the little anterior angle diamond saw blade of a kind of terraced tooth.
Background technology
When sawing sheet material, easily there is the phenomenon of chip in carpenter Furniture Factory, for this reason, equipment devises head saw and secondary saw, head saw is responsible for sawed-off from top to bottom, and pre-paddle-tumble is from the bottom up responsible for by secondary saw.Object first the veneer of reverse side is marked a groove in advance, prevents sheet material reverse side chip.The pre-paddle-tumble saw blade of prior art is designed to monolithic mostly, and angle design is less, and when pre-paddle-tumble, sawing is not sharp, and sawing rough surface does not reach requirement, and is inconvenient to regulate sawing width.And the cutter head of existing saw blade selects carbide bit, and service life is shorter, its sawing time is 6-8 hour.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of hardness is high, the little anterior angle diamond saw blade of the terraced tooth of long service life.
The purpose of this utility model is achieved through the following technical solutions: the little anterior angle diamond saw blade of a kind of terraced tooth, comprise saw bit matrix, several blades and several sawtooth, saw bit matrix is circular, sawtooth is evenly distributed in saw bit matrix circumferentially, sawtooth is provided with the mounting groove for installing blade, blade is arranged in mounting groove, blade comprises substrate and diamond layer, substrate is arranged between sawtooth and diamond layer, the anterior angle of blade is 4 °, rake face is that trapezoidal, trapezoidal upper base points to outside.
Described saw bit matrix is provided with silencing groove, and silencing groove is evenly distributed on saw bit matrix 1.
Described saw bit matrix is provided with installing hole.
Described blade is the diamond composite blade of less than 30 microns.
The utility model has the following advantages:
1, due to the hardness of diamond composite blade is Cemented Carbide Hardness more than 80 times, by the diamond composite blade of less than 30 microns selected, can make be the 30-80 of conventional cemented carbide saw blade the service life of this saw blade, make this saw blade lifetime long, and reduce the frequency changing saw blade, alleviate the labour intensity of staff, cost-saving, improve production efficiency;
2, the anterior angle of blade is 4 degree, and compared to original 10 degree of anterior angles, anterior angle is less, and not only fineness is good on the surface of sawing, and the service life of saw blade is longer;
3, due to saw blade service time longer after, cutter head can reduce by abrasion width, and the width of paddle-tumble also can diminish, it is trapezoidal by rake face is designed to, the width of sawing can be adjusted by up-down adjustment machine tool chief axis, extend the service life of saw blade, reduce the replacement frequency of saw blade.
Accompanying drawing explanation
Fig. 1 is the structural representation of the little anterior angle diamond saw blade of a kind of terraced tooth;
Fig. 2 is the partial enlarged drawing of sawtooth;
Fig. 3 is that sectional view is looked on a left side for the little anterior angle diamond saw blade of a kind of terraced tooth;
In figure, 1-saw bit matrix, 2-blade, 21-substrate, 22-diamond layer, 3-sawtooth, 4-silencing groove, 5-installing hole.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, Fig. 2, shown in Fig. 3, the little anterior angle diamond saw blade of a kind of terraced tooth, comprise saw bit matrix 1, several blade 2 and several sawtooth 3, saw bit matrix 1 is circular, sawtooth 3 is evenly distributed in saw bit matrix 1 circumferentially, sawtooth 3 is provided with the mounting groove for installing blade 2, blade 2 is arranged in mounting groove, blade 2 can pass through welded and installed, the method bonding strength is high, but blade 2 is difficult to after wearing and tearing change, also can be connected by insert, the method can be changed after blade 2 weares and teares, improve the utilization rate of saw bit matrix 1, and blade 2 can make polygon, each limit can as cutting edge, improve the utilization rate of blade 2, prevent waste of material, cost-saving, blade 2 comprises substrate 21 and diamond layer 22, substrate 21 is arranged between sawtooth 3 and diamond layer 22, blade 2 is the diamond compact of less than 30 microns, its anterior angle is 4 °, rake face is trapezoidal, trapezoidal upper base points to outside, when sawing, the saw blade sulculus that pre-standardized bar is identical with head saw sawing width on sheet material, to cut away the veneer that bottom sheets is harder, material chip can be prevented with this, after saw blade service time is longer, cutter head can reduce by abrasion width, the width of paddle-tumble also can diminish, but because rake face is designed to trapezoidal, the width of sawing can be adjusted by up-down adjustment machine tool chief axis, extend the service life of saw blade, reduce the replacement frequency of saw blade.
In the present embodiment, described saw bit matrix 1 is provided with silencing groove 4, and silencing groove 4 is evenly distributed on saw bit matrix 1, and silencing groove 4 can eliminate saw blade when High Rotation Speed because of the noise caused that resonates.
In the present embodiment, described saw bit matrix 1 is provided with installing hole 5, and saw blade is connected with providing the axle of cutting force by installing hole 5.
