Description
Technical field
The utility model relates to be related to a kind of saw blade, more particularly to a kind of silent saw blade.
Background technique
Saw blade is the general designation for cutting the thin slice circular knives of solid material.Saw blade can be divided into: for stone material cutting
Diamond saw blade；HSS sawblade (not tungsten carbide button cutter head) for metal material cutting；For solid wood, furniture,
The hard alloy saw blade of the cuttings such as wood-based plate, aluminium alloy, aluminum profile, radiator, plastics, plastic-steel.The quality of saw blade depends on saw
The quality of piece steel itself or other materials, in order to cut some special substances, it is also necessary to inlay difference on saw blade
Cutter head.
But in blades machining and the research process of material, it has been found that material of saw blade itself and the matter for being not equal to saw blade
Amount, other than the steel of high standard, the shape of saw blade, machining accuracy also will affect saw blade quality.
Experiment discovery, vibration of the quality and saw blade of saw blade in high-speed rotation, noise have a biggish relationship, and saw blade
The raising of shape and machining accuracy plays the role of very big for reducing vibration of the saw blade in high-speed rotation, reduction noise.
It has been investigated that vibration of the saw blade in high-speed rotation during can be effectively reduced some through slots are arranged on saw blade
With resulting noise, resulting antidetonation noise reduction effect can even be greater than the effect for directly promoting saw blade material.But
It will be apparent that and the slot of not all shape there is preferable antidetonation erasure effect, the slot of only some specific shapes can play
Preferable antidetonation erasure effect.
For this purpose, inventor is dedicated to improving the quality of saw blade by the way that some slots with noise reduction anti seismic efficiency are arranged, lead to
The improvement crossed on saw-blade structure improves blades machining technique, improves the quality of saw blade.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of silent saw blades.
The technical solution of the utility model is specific as follows: a kind of silent saw blade, and the silent saw blade includes saw bit matrix, institute
Saw bit matrix side is stated equipped with multiple sawtooth, the saw bit matrix center position is equipped with centre bore, edge on the saw bit matrix
Centre bore is symmetrically arranged with even number silencing seams, and a subregion is defined as between the adjacent silencing seams, appointing in the subregion
The ratio of space width of two adjacent sawtooth of anticipating is 100:95, and the space width of the sawtooth is symmetrical along the centre bore
Distribution.
Further, the silencing seams are integrally in serpentine shape and one end is placed in two adjacent sawtooth middle positions
The stop hole on the saw bit matrix is arranged in place, other end connection one.
Further, the stop hole is inlaid with fastener.
The utility model has the following beneficial effects: the service life is long, stability is preferable, can make being total in each region on saw blade
It shakes different, offsets each other between them, noise reduction effect is more preferable.
Detailed description of the invention
Fig. 1 is silent saw blade overall structure diagram described in the utility model；
Fig. 2 is an embodiment of the present invention subregion schematic diagram；
In figure, label 1 is saw bit matrix, 10 is sawtooth, 11 is silencing seams, 12 is stop hole, 13 is center hole, 14 is
One subregion, 15 be the second subregion, 13 be third subregion, 14 be the 4th subregion.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is explained in further detail the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
On the contrary, the utility model cover it is any be defined by the claims do in the spirit and scope of the utility model
Substitution, modification, equivalent method and scheme.Further, right below in order to make the public have a better understanding the utility model
It is detailed to describe some specific detail sections in the datail description of the utility model.Do not have for a person skilled in the art
The utility model can also be understood completely in the description of these detail sections.With reference to the accompanying drawing with specific embodiment, to this reality
With novel further explanation.
As shown in Figure 1, being a kind of silent saw blade overall structure diagram provided by the utility model, the silent saw blade
Including saw bit matrix 1,1 side of saw bit matrix is equipped with multiple sawtooth 10, and 1 center position of saw bit matrix is equipped with center
Hole 13 is symmetrically arranged with even number silencing seams 11 along centre bore on the saw bit matrix 1, and the whole silencing seams 11 are in serpentine shape
And one end is placed in two adjacent 10 middle positions of the sawtooth, other end connection one is arranged on the saw bit matrix 1
Stop hole 12, the stop hole 12 are inlaid with fastener；The effect of the silencing seams 11 is to improve the overall structural strength of saw blade
With saw blade in high-speed rotation, offsets saw blade and brought in radial directions with the internal stress and vibration in circumferential direction and thus
Noise, the effect of the silencing seams 11 be also embodied in improve can improve saw blade material capability and saw blade entirety ratio table
Area improves hardness and scattering effect, prevents saw blade heating too fast.The fastener can greatly offset vibration, eliminate noise.
A subregion is defined as between the adjacent silencing seams 11, the adjacent saw of any two in the subregion
The ratio of the space width of tooth 10 is 100:95, and the space width of the sawtooth 10 is symmetrical along the centre bore, i.e. guarantee institute
State the stability of saw bit matrix 1, balance.
As shown in Fig. 2, being an embodiment of the present invention subregion schematic diagram, the silencing seams 11 are four, described in four
The saw bit matrix 1 is defined as the first subregion 14, the second subregion 15, third subregion 16 and the 4th subregion 17, institute by silencing seams 11
It states 10 space width of sawtooth to taper off distribution in 14 center of the first subregion to both sides, 10 space width of sawtooth is in the second subregion
15 centers are incremented by distribution to both sides；Space width in the subregion is symmetrical along the centre bore 13, i.e., and described first
Space width in subregion 14 and the third subregion 16 is symmetrical, second subregion 15 and the space width in the 4th 17 subregion
Symmetrically；The resonance on saw blade in each region can be made different in this way, offset each other between them.
