Cutter tooth length be up to 1.5~3 times of the cutter tooth length positioned at both ends.
Compared with immediate prior art, the cutter head that cuts of the invention has the advantages that：
The cutter head that cuts of the present invention has good cutting and grinding function, and the energy under the working condition that high-speed dry is cut concurrently
Enough prevent from cutting bursting apart and being broken for cutter head, stock-removing efficiency and service life can be significantly improved, the marble that is particularly suitable for use in, flower
Gang Yan, cement concrete are cut.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram for cutting cutter head at the first visual angle of the invention.
Fig. 2 is the dimensional structure diagram for cutting cutter head at another visual angle of the present invention.
Fig. 3 is the schematic cross-section for cutting the non-cutting face side of cutter head of the present invention.
Embodiment
The cutter head that cuts of the present invention is further elaborated below with reference to specific embodiment, to the skill to the present invention
Art scheme makes more complete and clear explanation.
Fig. 1-3 shows that the present invention's cuts cutter head, and it includes the ring-type formed by multiple cutters tooth 10,12 being arranged side by side
Cutting portion (right part shown in dotted lines in Figure 2), the cutwork face 11 of ring-type cutting portion is arc section.Between both ends
The length of cutter tooth 12 be more than the length of cutter tooth 10 at both ends, and the cutter tooth between both ends prolongs towards the non-cutting direction of working face 13
Stretch to form fan-shaped grinding part (left part shown in dotted lines in Figure 2), and the ring-type cutting portion and the knife of fan-shaped grinding part
Tooth has identical thickness.After being matrix assembling, in fan-shaped grinding part insertion matrix thus can only play a part of grinding, and
Ring-type cutting portion mainly plays shear action.It can be seen that each cutter tooth in the cutter tooth is from non-cutting working face
13 have the width gradually to broaden to cutwork face 11, so as to be advantageous to keep the self-sharpening of cutter tooth in working angles.Such as Fig. 1
It is shown, the teeth groove of non-cutting working face 13 is extended between adjacent cutter tooth formed with self-cutting working face 11.As shown in Fig. 2
Cut and be provided with ring-type cutting portion and fan-shaped grinding part on two relative main surfaces of cutter head；And on described two main surfaces
The mutual stagger setting of teeth groove.The angle of the central axial direction of the cutter tooth for cutting cutter head and the tangential direction of the arc section
Degree a meets relational expression：90 ° of 45 °≤a ＜, preferably 60 °≤a≤80 °.If the two angle to stagger is less than 45 °, will cause
Stock-removing efficiency significantly reduces.And cause cutting abrasion increase if central axial direction is vertical with the tangential direction of arc section simultaneously
It is unfavorable for cutting, nor beneficial to grinding.As shown in figure 1, teeth groove is by depth different the first teeth groove 14 and the second teeth groove 15
Form；The depth of first teeth groove 14 is more than the depth of the second teeth groove 15, and the first teeth groove 14 is located at the surface of ring-type cutting portion,
And the second teeth groove 15 extends to the surface of ring-type cutting portion from non-cutting working face 13.It is so designed that and not only ensure that high-speed cutting
Under the conditions of chip removal, and be also beneficial to maintain to cut the overall rigidity of cutter head, can when being cut to materials such as concrete, ceramics
The higher cutting speed of maintenance is without cracking or bursting apart.Caused internal stress is along the cutting for cutting cutter head in working angles
Work is transmitted towards fan-shaped grinding part, is distributed and dissipated, and so as to avoid internal stress from being accumulated near the bottom of groove, can be kept away
Exempt from the problem of Cracking under high-speed cutting.In the present invention, the ring-type cutting portion and the cutter tooth of fan-shaped grinding part have identical
Thickness, and the two is continuous entirety, is advantageous to keep overall rigidity, can both solve conventional annular cutter head cutting production
Raw crack problem, can also solve conventional grinding surface and (be commonly attached in the outside wall surface of matrix, its thickness is less than bite
Head thickness) problem of bursting apart.And the non-cutting working face for cutting cutter head and being formed of the present invention, compared to common circular arc knot
Conjunction face, the area of faying face is significantly improved, so as to also improve bond strength.For the combination ensured and matrix is good, such as
Shown in Fig. 3, non-cutting working face 13 is internally provided with the T-slot 16 for being engaged with matrix border.It is overall in order to ensure
Stock-removing efficiency, the surface area of fan-shaped grinding part could be arranged to the 50~100% of the surface area of the ring-type cutting portion, so as to i.e.
The smooth work of cutter head can be maintained to cut, be advantageous to maintain good ground effect.Any main surface for cutting cutter head
On the number of cutter tooth be 4~8, and the cutter tooth length between both ends is up to the cutter tooth length positioned at both ends
1.5~3 times.
In the present invention, cutting cutter head and matrix can be combined together using well known method, such as can pass through hot pressing
Sintering or the mode of welding (being preferably soldering) are incorporated on the flange of matrix.If matrix size is smaller, such as size is small
When 150mm, conventional hot-pressing sintering method can be generally used in order to reduce cost.And in order to ensure matrix and cut cutter head
Bond strength can use soldering (such as vacuum brazing, induction brazing, laser soldering etc.) technique.Described matrix is led in the present invention
Steel can often be used, such as 65Mn steel etc. obtains that by machining (such as inner fovea part can be formed by machining process
And flange, and the mounting hole at center).And it is described cut cutter head can use metallic bond and hard particles by dispensing,
Mixing cold pressing, the mode of hot pressed sintering (or freely sintering) are formed, such as can use conventional iron-based, copper-based or cobalt-based metal
Bonding agent, in order to improve the bond strength between its grinding performance, especially hard particles and bonding agent, it can preferably use pre- close
Bronze and the form of metal powder blending.
For the ordinary skill in the art, simply the present invention is exemplarily described for specific embodiment,
Obviously present invention specific implementation is not subject to the restrictions described above, and is entered as long as employing the inventive concept and technical scheme of the present invention
The improvement of capable various unsubstantialities, or it is not improved by the present invention design and technical scheme directly apply to other occasions
, within protection scope of the present invention.
