Description
Technical field
The utility model relates to oil bit composite polycrystal-diamond.
Background technology
Oil bit composite polycrystal-diamond comprises the polycrystalline diamond of hard alloy substrate and substrates; described matrix is the structure of cylinder; in prior art; around matrix, do not protect the facility in footpath portion, such composite polycrystal-diamond has the shortcoming that easily wear and tear in footpath portion, service life is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of footpath portion is not easy to wear, the New polycrystal diamond composite sheet of long service life.
The technical solution of the utility model is such: a kind of New polycrystal diamond composite sheet, comprise composite sheet body, described composite sheet body comprises again the polycrystalline diamond of hard alloy substrate and substrates, described matrix is the structure of cylinder, it is characterized in that: described matrix side attachment has the second polycrystalline diamond layer.
Say further, the second described polycrystalline diamond layer presents interval and arranges.
Say further, described spaced second polycrystalline diamond layer has the structure of protrusion at the circumference of matrix, the structural outer of protrusion is larger than position, interval curvature.
Say further, the second described polycrystalline diamond layer thickness, between 0.8mm and 1.5mm, sets off part below in addition.
Say further, described set off part and matrix is integrally.
The beneficial effects of the utility model are: such oil bit gauge composite polycrystal-diamond has that footpath portion is not easy to wear, the advantage of long service life;
The second described polycrystalline diamond layer presents interval and arranges, and also has cost-saving advantage;
Described spaced second polycrystalline diamond layer has the structure of protrusion at the circumference of matrix, the structural outer of protrusion is larger than position, interval curvature, has the better advantage of abrasive body side grinding effect;
The second described polycrystalline diamond layer thickness, between 0.8mm and 1.5mm, sets off part in addition below, has and can ensure normal use, have again cost-effective advantage.
Described set off part and matrix is integrally, there is advantage easy to manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cross-sectional view of Fig. 1.
Wherein: 1, matrix 2, polycrystalline diamond 3, second polycrystalline diamond layer 4, set off part.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, 2, a kind of New polycrystal diamond composite sheet, comprise composite sheet body, described composite sheet body comprises again the polycrystalline diamond 2 of hard alloy substrate 1 and substrates, described matrix is the structure of cylinder, it is characterized in that: described matrix side attachment has the second polycrystalline diamond layer 3.
Say further, the second described polycrystalline diamond layer presents interval and arranges.
Say further, described spaced second polycrystalline diamond layer has the structure of protrusion at the circumference of matrix, the structural outer of protrusion is larger than position, interval curvature.
Say further, the second described polycrystalline diamond layer thickness, between 0.8mm and 1.5mm, sets off part 4 below in addition.
Say further, described set off part and matrix is integrally.
