A kind of braze welding type polygon compounded superhard blade
Technical field
The utility model relates to a kind of braze welding type polygon compounded superhard blade, belongs to technical field of tools.
Background technology
The structure of existing braze welding type blade is single, makes the cost of charp tool increase.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of braze welding type polygon compounded superhard blade.
The utility model solves the technical scheme that its technical problem adopted: a kind of braze welding type polygon compounded superhard blade, comprise superhard cutter head and matrix, and said matrix is a polygon, and the wedge angle position on the matrix offers groove, and superhard cutter head is welded in the groove.
Each wedge angle of said polygon matrix is provided with groove.
Said groove cross section be shaped as any one of polygon or pointed shape or circular arc or ellipse or polygon wedge angle.
Said superhard cutter head is welded on the surface of polygon matrix.
Said superhard cutter head be welded on the top of polygon matrix or below.
Said superhard cutter head is welded on the side of polygon matrix.
Matrix material is high-speed steel or carbide alloy.
When superhard cutter head was other superhard material except that carbide alloy, the brazing metal of titaniferous was adopted in welding.
When superhard cutter head was other superhard material except that carbide alloy, solder technology adopted vacuum welding or inert gas-shielded arc welding.
When superhard cutter head is carbide alloy, can adopt brazing mode arbitrarily.
Special scolder is adopted in soldering, welding under vacuum or inert gas shielding.The temperature of welding is above 800 ℃.
Superhard tool tip material is any one materials such as polycrystalline cubic boron nitride (PCBN), polycrystalline diamond (PCD), chemical vapour deposition diamond (CVDD), single-crystal diamond, ultra hard ceramic, high-anti-friction hard alloy.
After superhard cutter head was welded in the groove of matrix, sharpening on the cutter grinding machine of special use promptly was made into the compounded superhard blade of finished product.
Polygon comprises triangle, rectangle, rhombus, and other equilateral or unequal-sided arbitrary polygon shape.
Said superhard cutter head is any one cutter head processed in polycrystalline cubic boron nitride sintered body, polycrystalline diamond sintered body, silicon nitride, aluminium oxide, titanium nitride, the titanium carbide.
The beneficial effect of the utility model is: solved the glomerocryst Superhard composite materials is prone to layering or fracture in processing with in using problem, product quality is more stable.
Because of many times of increases of cutting edge quantity, brought the many times of prolongations in service life, also greatly reduced client's use cost.

The specific embodiment
Referring to figs. 1 through Fig. 6 the embodiment of the utility model is described.Obviously, the many modifications made based on the aim of the utility model of those skilled in the art and the variation protection domain that belongs to the utility model.
Embodiment 1: as shown in Figure 1, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 1 is the rhombus in the polygon, and locating hole 2 is arranged on the matrix 1; The upper and lower position of 2 relative angles offers groove on the matrix 1, and the superhard cutter head 3,4,5,6 that shape and groove match is welded in the groove.
Embodiment 2: as shown in Figure 2, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 1 is the rhombus in the polygon, and locating hole 2 is arranged on the matrix 1; The position of 2 relative angles offers groove on the matrix 1, and the superhard cutter head 7,8 that shape and groove match is welded in the groove.
Embodiment 3: as shown in Figure 3, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 11 is the rectangle in the polygon, and locating hole 2 is arranged on the matrix 11; The position in 4 bights offers groove on the matrix 11, and the superhard cutter head 9,10,12,13 that shape and groove match is welded in the groove.
Embodiment 4: as shown in Figure 4, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 17 is the triangle in the polygon, and locating hole 2 is arranged on the matrix 17; The position in 3 bights offers groove on the matrix 17, and the superhard cutter head 14,15,16 that shape and groove match is welded in the groove.
Embodiment 5: as shown in Figure 5, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 21 is the hexagon in the polygon, and locating hole 2 is arranged on the matrix 21; The position in 3 bights offers groove on the matrix 21, and the superhard cutter head 18,19,20 that shape and groove match is welded in the groove.
Embodiment 6: as shown in Figure 6, a kind of braze welding type polygon compounded superhard blade comprises superhard cutter head and matrix, and said matrix 22 is the rectangle in the polygon, and locating hole 2 is arranged on the matrix 22; The position at 2 diagonal angles offers groove on the matrix 22, and the superhard cutter head 23,24 that shape and groove match is welded in the groove; The length of one side cutting edge of superhard cutter head 23,24 is greater than the length of opposite side.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
