Abstract

The invention provides a grooving saw blade. The grooving saw blade comprises a saw blade body and sawteeth. The sawteeth are continuously arranged on the saw blade body. Cutter bits are arranged on the sawteeth. A center hole is formed in the saw blade body. Silencing expansion grooves are evenly formed around the center hole. Each sawtooth comprises a front angle, a rear angle, a transverse front angle, a lateral rear angle, an apex angle and a lateral centripetal angle. The front angle is 18 degrees. The rear angle is 15 degrees. The transverse front angle is 0 degree. The lateral rear angle is 1.5 degrees. The apex angle is 10 degrees. The lateral centripetal angle is 1 degree. The service life of the saw blade can be prolonged, the cutting precision is improved, sawing stability is improved, the phenomenon of edge breakage is avoided, the production efficiency is improved, and the cost is reduced.

Description

A kind of slitting saw-blade

Technical field

The invention relates to cutting tool field, particularly relates to a kind of slitting saw-blade.

Background technology

The material used before being different from is to produce saw blade; Use now superhard carbide alloy as cutting edge, undertaken realizing cutting at a high speed by High Rotation Speed.There is end in service life in cutting tool in the past, groove width is uneven when board-like and solid wood slotting, the phenomenon that production efficiency is on the low side, have when sawing and larger collapse limit phenomenon, affect attractive in appearance, the debugging difficulty of saw blade is also very large, causes shortcomings such as cannot docking during last assembling, too increases repetition recruitment simultaneously, waste of material, the problem of energy waste, make the shortcomings such as production cost raising.

Summary of the invention

The problem that the invention will solve is to provide a kind of simple to operate, and production efficiency has height, is applicable to a kind of slitting saw-blade of multiple material.

For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of slitting saw-blade, comprises blade body and sawtooth, and described blade body arranges sawtooth continuously, and described sawtooth is provided with cutter head; Be provided with centre bore in described blade body, around described centre bore, be evenly provided with noise reduction expansion slot; Described sawtooth comprises anterior angle, relief angle, side rake angle, side relief angle, the centripetal angle in tip inclination angle and side; Described anterior angle is 18 °; Described relief angle is 15 °; Described side rake angle is 0 °; Described side relief angle is 1.5 °; Described tip inclination angle is 10 °; Centripetal angle, described side is 1 °.

The advantage that the invention has and good effect are: increase noise reduction expansion slot and decrease the noise and thermal deformation that produce when sawing; Also can increase the service life of saw blade, improve the precision of cutting, the stability of sawing be increased, has stopped the phenomenon collapsing limit, improve production efficiency, saved cost.

Detailed description of the invention

Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.

As shown in the figure, the invention provides a kind of slitting saw-blade, comprises blade body 4 and sawtooth 1, blade body 4 arranges sawtooth 1 continuously, sawtooth 1 is provided with cutter head 5; Be provided with centre bore 3 in blade body 4, around centre bore 3, be evenly provided with noise reduction expansion slot 2; Sawtooth comprises the centripetal angle 11 in anterior angle 6, relief angle 7, side rake angle 8, side relief angle 9, tip inclination angle 10 and side; Anterior angle 6 is 18 °; Relief angle 7 is 15 °; Side rake angle 8 is 0 °; Side relief angle 9 is 1.5 °; Tip inclination angle 10 is 10 °; Centripetal angle 11, side is 1 °.

Shown in Fig. 2, Fig. 3, Fig. 4, anterior angle 6 is the angles after cutter head 5 between end projection 62 and basal plane 61, and basal plane 61 is perpendicular to the direction of feed 71 of sawtooth 1; Anterior angle 6 is the design of 18 °, and the speed that improve cutting to a greater extent, makes production efficiency effectively improve.

Relief angle 7 is angles of the direction of feed 71 of cutter head 5 top projection 72 and sawtooth 1; Side relief angle 9 is the projection 91 of side, cutter head 5 top and the angle of sawtooth 1 direction of feed 71; Relief angle 7 is 15 °, and side relief angle 9 is designs of 1.5 °, can effectively reduce frictional force, reduces the heat produced in sawing.

Side rake angle 8 is angles of the transverse projection 81 on axis 101 and cutter head 5 top; Axis 101 is vertical with basal plane 61 by centre bore 3; Tip inclination angle 10 is the first end projection 102 of cutter head 5 and the angle of axis 101, and side rake angle 8 is designs of 0 °, and tip inclination angle 10 adopts the design of 10 °, adds the sharpness of saw blade, adds fineness.

Centripetal angle 11, side is basal planes 61 and the angle of cutter head 5 side projection 111, and centripetal angle 11, side is generations of the design of 1 ° heat when decreasing sawing, has saved the time, has improve production efficiency.

With improvement, saw blade lifetime is extended according to above design, the raising of cutting precision is that the stability of sawing also increases, stop the phenomenon collapsing limit, improve the efficiency of production, decrease the repetition recruitment of much taking together, reduce human cost, reduce energy resource consumption, reach the effect of energy-saving and emission-reduction, save production cost.

Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
