Abstract
The utility model discloses a kind of polygon diamond compact, including cement carbide substrate, the upper surface of the cement carbide substrate is connected to the bottom end of polycrystalline diamond layer, and the cross-sectional diameter of polycrystalline diamond layer is gradually reduced from bottom to up.The polygon diamond compact, pass through the improvement to polycrystalline diamond layer surface texture, make diamond compact in practical drilling process, the side-flank surfaces of polycrystalline diamond layer can come into full contact with soil and rock, to indirectly improve diamond compact to the drilling efficiency of soil and rock, and in actually probing, the high-speed rotation of polycrystalline diamond layer, the diamond of gap two sides can be made efficiently to drill soil, it is more reasonable to design, and reduces the processing cutting difficulty of diamond.
Description
Technical field
The utility model relates to diamond compact technical field, specially a kind of polygon diamond compact.
Background technique
With the development of science and technology, the use scope to diamond is also gradually extending, diamond is because of itself high rigidity
Material feature, cement carbide substrates of arranging in pairs or groups are popped one's head in more as diamond compact drilling, used in the engineering of petroleum and coal seam probing
In, but be mostly smooth knot there is the side surface of diamond compact when existing diamond compact is drilled in rock stratum
Structure, primarily serve probing effect is the structure on its top, and since the soil and rock structure on stratum is very close, so Buddha's warrior attendant
Inefficient disadvantage of the stone composite sheet in actually probing.In view of the above-mentioned problems, being badly in need of the base in original diamond compact
Innovative design is carried out on plinth.
Utility model content
The purpose of this utility model is to provide a kind of polygon diamond compacts, to solve to mention in above-mentioned background technique
The side surface of diamond compact is mostly smooth structure out, and primarily serve probing effect is the structure on its top, and due to ground
The soil and rock structure of layer is very close, so inefficient problem of the diamond compact in actually probing.
To achieve the above object, the utility model provides the following technical solutions: a kind of polygon diamond compact, including
The upper surface of cement carbide substrate, the cement carbide substrate is connected to the bottom end of polycrystalline diamond layer, and polycrystalline diamond layer
Cross-sectional diameter be gradually reduced from bottom to up, the polycrystalline diamond layer successively decreases setting in gradient from bottom to up, and plycrystalline diamond gold
The Dispersion on surface of hard rock layer is provided with multiple polygon facets, and gap is provided on polycrystalline diamond layer.
Preferably, the gap is provided with the top of polycrystalline diamond layer, and the height of the polycrystalline diamond layer on the left of gap
Degree is lower than right side.
Compared with prior art, the utility model has the beneficial effects that the polygon diamond compact, by plycrystalline diamond
The improvement of diamond layer surface texture makes diamond compact in practical drilling process, the side-flank surfaces of polycrystalline diamond layer
It can be come into full contact with soil and rock, so that diamond compact is indirectly improved to the drilling efficiency of soil and rock, and
When practical probing, the high-speed rotation of polycrystalline diamond layer can make the diamond of gap two sides efficiently drill soil, if
It is more reasonable to count, and reduces the processing cutting difficulty of diamond.
Detailed description of the invention
Fig. 1 is the utility model entirety positive structure diagram；
Fig. 2 is the utility model overlooking structure diagram.
In figure: 1, cement carbide substrate；2, polycrystalline diamond layer；3, gap.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of polygon diamond compact, including hard
Matter alloy substrates 1, polycrystalline diamond layer 2 and gap 3, the upper surface of cement carbide substrate 1 are connected to the bottom of polycrystalline diamond layer 2
End, and the cross-sectional diameter of polycrystalline diamond layer 2 is gradually reduced from bottom to up.
Polycrystalline diamond layer 2 successively decreases setting in gradient from bottom to up, and the Dispersion on surface of polycrystalline diamond layer 2 be provided with it is more
A polygon facet, and gap 3 is provided on polycrystalline diamond layer 2, the design of 2 surface texture of polycrystalline diamond layer is convenient for
In practical drilling process, the polygon facet on surface can come into full contact with soil and rock, avoid the top of only drill bit in reality
The problem of border is drilled, it is more efficient.
Gap 3 is provided with the top of polycrystalline diamond layer 2, and the height of the polycrystalline diamond layer 2 in 3 left side of gap is lower than
Right side, when diamond compact integrally starts probing, the polycrystalline diamond layers 2 of 3 two sides of gap can be the high-speed rotation the case where
Under, by way of reducing stiction, to promote the initial formation of drilling hole faster, in order to subsequent probing work
It carries out.
Working principle: when diamond compact integrally starts probing, the polycrystalline diamond layer 2 of 3 two sides of gap can be in height
In the case where speed rotation, by way of reducing stiction, to promote the initial formation of drilling hole faster, in order to subsequent
Probing work progress, the design of 2 surface texture of polycrystalline diamond layer, convenient in practical drilling process, surface it is more
Side shape face can come into full contact with soil and rock, avoid the top of only drill bit the problem of actually drilling, more efficient, this is just
It is the working principle of the polygon diamond compact.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
