Abstract
The utility model discloses a kind of special diamond compact making wearing piece, described diamond compact comprises two diamond compact monomers in column structure, wherein arbitrary diamond compact monomer is included hard alloy substrate layer and is sintered in the polycrystalline diamond layer of its upper surface by HTHP, and described two diamond compact monomers are by forming an organic whole after hard alloy substrate layer soffit sintering each other.The utility model structure is simple, by sintering, two columned diamond compacts are combined, successfully solve composite sheet diamond layer and the matrix two ends problem that loss differs because abrasion resistance is different, avoid the generation of tapering, improve the stability of wearing piece, extend the application life of wearing piece, improve the operating efficiency of wearing piece.
Description
Technical field
The utility model relates to a kind of special diamond compact, particularly relate to a kind of diamond compact making drill bit wearing piece, can be applicable on oil drilling, geological prospecting, coalfield drilling drill bit and the industry such as machine tools, belong to hard alloy complex sheet technical field.
Background technology
At present, diamond compact is widely used in oil drilling industry, and the diverse location of drilling bit has the requirement of difference in functionality to diamond compact, wherein makes wearing piece in some special position composite sheet and uses.
In prior art, this wearing piece all uses common diamond compact, but in its course of work, the two ends of wearing piece all can be worn, and common diamond compact is because one end is diamond layer, the other end is hard alloy layer, and the abrasion resistance of alloy-layer is far below diamond layer, this just causes the prolongation along with service time, tapering is there is in wearing piece because the degree of wear at two ends is different, wearing piece also therefore hydraulic performance decline even scrap, the simultaneously frequent replacing of wearing piece also can greatly affect operating efficiency and increase job costs.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides that a kind of more wear-resistant, two ends wearing and tearing gap is little, the special diamond compact of long service life, it efficiently solves diamond compact wearing piece and easily weares and teares and occur tapering and consume excessive problem, greatly extends the application life of wearing piece.
The utility model solves the technical scheme that its technical problem adopts:
A kind of special diamond compact making wearing piece, described diamond compact comprises two diamond compact monomers in column structure, wherein arbitrary diamond compact monomer is included hard alloy substrate layer and is sintered in the polycrystalline diamond layer of its upper surface by HTHP, and described two diamond compact monomers are by forming an organic whole after hard alloy substrate layer soffit sintering each other.
As the improvement of technique scheme, described diamond compact monomer is preferably set to cylinder.
The beneficial effect that the utility model brings has:
The utility model structure is simple, by sintering, two diamond compacts are combined, successfully solve composite sheet diamond layer and the base layer two ends problem that loss differs because abrasion resistance is different, avoid the generation of tapering, improve the stability of wearing piece, extend the application life of wearing piece, improve the operating efficiency of wearing piece.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is control group structural representations of the present utility model.
Detailed description of the invention
With reference to accompanying drawing 1, the utility model is a kind of special diamond compact making wearing piece, and it is made up of two cylindrical diamond compact monomers.Further, polycrystalline diamond layer 2, two hard alloy substrate layers 1 that diamond compact monomer comprises hard alloy substrate layer 1 and is sintered in its upper surface by HTHP are then sintered in one with soffit each other for benchmark and then form an organic whole.
With reference to accompanying drawing 2, for the former diamond compact wearing piece that the utility model improves, it comprises hard alloy substrate layer 1 and polycrystalline diamond layer 2, and wherein polycrystalline diamond layer 2 is sintered in the upper surface of hard alloy substrate layer 1 by HTHP, two kinds of wearing pieces measure-alike.
The utility model structure is simple, novel wear resistant part after improvement greatly solves because diamond layer and base layer two ends abrasion resistance differ greatly and produce the problem of tapering, and improve the stability of wearing piece functional performance, extend the application life of wearing piece, decrease the difference between individuality, finally reach and improve overall application life and the object of performance.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
