Specific implementation mode
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.
It should be noted that term used herein above is merely to describe specific implementation mode, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in the present specification using term " including " and/or " packet
Include " when, indicate existing characteristics, step, operation, device, component and/or combination thereof.
As background technology is introduced, cutting efficiency exists in the prior art, replaces speed and cannot meet production requirement
Deficiency, in order to solve technical problem as above, present applicant proposes a kind of saw blades of fast changeable cutter block.
In a kind of typical embodiment of the application, as shown in Fig. 1-Figure 15, a kind of fast changeable cutter block is provided
Saw blade, the center of including circular saw blade substrate 2, circular saw blade substrate 2 is equipped with centre bore 10, the outside surrounding of centre bore 10
Multiple mounting holes 3 are set, mounting hole 3 can be evenly distributed with can also unevenness portion, depending on the saw used with specific reference to producer.
The radially opposite sides of centre bore 10 are arranged with the processing and peace of hole for hoist 4, mounting hole 3 and hole for hoist 4 for saw blade
Dress.
The circular saw blade substrate 2 is along the multiple toothholders 1 that do not divide equally of its circumferential directions, and the toothholder 1 is by two planes
It intersects to form, i.e., along the faces L 6 of the faces V 5 of 2 radial direction of circular saw blade substrate and tangential direction, (faces V 5, the faces L 6 are the similar V of shape
Type, the plane of L-type are herein similar V-type, the half of the plane of L-type).
Angle between the faces V 5 and the faces L 6 is less than 90 °, and the angle α of the faces V 5 and vertical direction is more than 0 ° and is less than etc.
In 10 °, the angle β of the faces L 6 and horizontal direction is more than 0 ° and is less than or equal to 15 °.
Cutter block 7 is fixed on toothholder 1, the top of toothholder 1 with contacted behind cutter head, rather than by cutter head trailing flank and toothholder 1V
The all contacts of face 5, can be mitigated the stress of fixed screw by the flexible deformation of metal, pass through the bullet of itself of circular saw blade substrate 2
Property deformation play the role of mechanical damping；When angle is less than 90 °, after cutter block 7 is installed, exist between cutter block 7 and circular saw blade substrate 2
One gap can inject liquid state colloid by top arc position, and a uniline protection interface is played after isocolloid solidification, from
And play the role of protecting cutter block.
The center in the faces L 6 has the threaded hole 8 positioned for cutter block 7, and it is heavy will to be carried by sunk screw
The cutter block 7 of the good cutting edge of reconditioning of head bore is fixed on toothholder 1；According to cut material difference, there are two types of combined situations, and one is ladders
Flat tooth cutter block is alternately fixed on toothholder, as shown in Fig. 8-Figure 13；One is the flat tooth cutter blocks of left and right chip dividing groove to be fixed on toothholder
On, as shown in Figure 14-Figure 15.
Cutter block 7 is installed on toothholder 1, and it is mechanical damping or filling to have buffer portion, the buffer portion 9 therebetween
Substance buffers.
By taking the saw blade of product specification D1*d*E1 (E) * Z as an example, wherein D1 is that the maximum outer circle of circular saw blade substrate 2 is straight
Diameter, 10 diameter of hole centered on d, E1 are the thickness of saw blade cutter head, and E is the thickness of circular saw blade substrate 2, and Z is the circle of circular saw blade substrate 2
The number of teeth on week.
The tooth pitch of circular saw blade substrate 2 is no longer set to a fixed value according to by the difference of cutting material, but has 1
A, 2 ... be up to Z different tooth pitches are formed by connecting；The difference of height of entire outer circle toothholder 1 can have 1,2 ... most
It is have Z-1 different tooth height differences more.
On saw blade installation can be clamped carbide tool-block, due to cutter block height be it is unified, by adjusting
The difference in height in the faces adjacent teeth toothholder L adjusts the difference in height of saw blade cutting edge, and to mitigate sawtooth cutting resistance, it is resistance to improve saw blade
Expenditure, difference in height range 0≤H≤0.5；Difference in height is different, and the diameter of a circle that cutting edge is formed is different, the cutting of a saw blade
Sword can form 2-10 circle.
Traditional blade teeth is away from being all that respectively, requirement of the cut substrate difference to tooth pitch sometimes is also different, therefore is ensureing
Under the premise of cut quality, excircle is grouped according to integer, the number of teeth in one group can be 1,2,3......n, in one group
Tooth pitch is identical, and a saw blade is in the majority can to divide Z groups, tooth pitch be respectively L1, L2, L3 ... Ln, n≤Z.
The application is carried under the premise of using conventional clamped cutter block by improving the geometric parameter of circular saw blade substrate
High cutting efficiency and replacement speed；According to the difference in height between each tooth of sintered carbide circular saw, realize saw blade in cutting process
In be divided into finishing tooth and roughing tooth, the cutting output of each tooth is disperseed also by difference in height.
The foregoing is merely the preferred embodiments of the application, are not intended to limit this application, for the skill of this field
For art personnel, the application can have various modifications and variations.Within the spirit and principles of this application, any made by repair
Change, equivalent replacement, improvement etc., should be included within the protection domain of the application.
