Specific embodiment
The utility model is described further referring to attached drawing.
A kind of silent saw blade, as shown in Figure 1, include blade body 1, be opened on 1 center of circle of blade body mounting hole 2,
It several sawtooth 3 for being fixedly connected on 1 excircle of blade body and is mounted on sawtooth 3 and meets cutter head 4 to cutting direction side,
Sawtooth 3 is uniformly distributed around the center of blade body 1, and chip pocket 5 is formed at the bottom of the tooth between sawtooth 3 and sawtooth 3.
As depicted in figs. 1 and 2, one side of the cutter head 4 far from mounting hole 2 is top surface, and top surface is downward backwards to the direction of cutting
It is obliquely installed, is symmetrically arranged with chamfering 6 along the axial two sides of blade body 1 on top surface, and two sides chamfering 6 is fallen on cutter head 4
Edged surface intersection, top surface are inverted V shaped.The position that V-arrangement tip contacts cutter head 4 with timber is sharper, advantageously reduces cutter head 4 and cuts
Resistance suffered when timber is cut, the generation of noise is reduced.
As shown in Figure 1, sawtooth 3 is fixedly installed the protrusion 7 of hump shape far from the side of cutter head 4, protrusion 7 is fixed at
The upper end of sawtooth 3；The high point of protrusion 7 is lower than the V-arrangement tip of cutter head 4, and protrusion 7 shortens the cutting distance of cutter tooth, can be effective
Ground avoids the excessive generation for leading to saw blade binding and hitting saw of the disposable amount of feeding of timber.
As shown in Figure 1, the keyway 8 of section semicircular in shape is offered on the inner wall of mounting hole 2, the Shi Gengping so that saw blade works
Surely, it prevents saw blade from slipping phenomenon occurring during working continuously, influences cutting accuracy.
As shown in Figure 1, offering three groups of expansion slots 9 by laser in blade body 1, three groups of expansion slots 9 are around blade body 1
Center be uniformly distributed；One end of expansion slot 9 is connected to chip pocket 5, and the other end of expansion slot 9 is in hook solid, the slot of expansion slot 9
Width extends along direction and slowly becomes smaller.The setting of expansion slot 9 can not only be effectively reduced hot shape of the blade body 1 in sawing
Become；It is transmitted at the same time it can also which the vibration generated when timber will be cut along the path of crotch, and it is offset, reduce noise
It generates.
As shown in Figure 1, offering three groups of vortex-like silencing grooves 10, three groups of vortex-like silencing grooves 10 by laser in blade body 1
Center around blade body 1 is uniformly distributed；Meanwhile the screw pitch of vortex-like silencing groove 10 slowly becomes smaller from outside to inside, vortex-like silencing groove
10 one end far from its center are arranged towards the outside of blade body 1, and saw blade can be cut wood by the setting of vortex-like silencing groove 10
The vibration generated when material is transmitted along the extending direction of vortex-like silencing groove 10, and it is offset, and reduces the generation of noise.
As shown in figure 3, the erasure effect of vortex-like silencing groove 10 in order to further increase, is filled in vortex-like silencing groove 10
Damping material 11, wherein damping material 11 is acoustical cotton.
As shown in Figure 1, offering along the circumferential direction of blade body 1 by laser three groups of curve silencing groove in blade body 1
12, three groups of curve silencing grooves 12 are uniformly distributed around the center of blade body 1, and are spaced and are arranged with vortex-like silencing groove 10；Curve disappears
The corrugation pitch of sound slot 12 becomes larger from edge backwards to cutting direction.Curve silencing groove 12 effectively prevents vibration from radially passing
It broadcasts, largely plays the role of reducing noise.
As shown in Figure 1, the outside of mounting hole 2 is uniformly provided with two groups of V-shaped blocking slots 13, between two groups of blocking slots 13
There are safe distances；The V-arrangement infall of slot 13 is being blocked by circular sliding slopes, is making to block the transition of 13 infall of slot more soft
With.The vibration for blocking slot 13 to generate when can further cut saw blade blocks, and destroys the propagation path of vibration, reduces noise
It generates.
As shown in Figure 1, the both ends of vortex-like silencing groove 10 and curve silencing groove 12 offer rounded through-hole 14, expansion
The crotch end of slot 9 also offers same through-hole 14, and opening up for through-hole 14 increases the contact surface of blade body 1 Yu air
Product, improves the thermal diffusivity of saw blade.
Working principle: when saw blade cuts timber, cutter head 4 takes the lead in contacting with timber, the vibration that cutter head 4 generates when cutting, according to
It is secondary to pass to sawtooth 3, then arrive blade body 1；And expansion slot 9, vortex-like silencing groove 10, curve silencing groove 12 and slot 13 is blocked to set
Setting is the propagation path for having blocked vibration nothing but, reduces the generation of noise to a certain extent；And it vibrates while transmitting, vibration
Dynamic to transmit along the path of vortex-like silencing groove 10 and curve silencing groove 12, vibration is also cancelled therewith；And with vortex-like silencing groove 10
The damping material 11 of interior filling is even more the effect for increasing vibration cancellation, creates a further reduction noise, reduces the dirt of noise
Dye.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
