The cylindrical hard alloy matrix for polycrystalline diamond compact is characterized in that the upper end surface of the matrix is provided with one or a plurality of projections; each projection is an annular projection (4,5) and shares the same circle center; an edge (3) of the upper end surface is provided with one or a plurality of sink troughs (2) annularly distributed at intervals; the sink troughs are in a structure of plane symmetry or central symmetry; and two adjacent projections form an annular groove. With the above structure, bonding capacity of a polycrystalline diamond layer and a hard alloy layer is effectively improved, a diamond layer thickness of a synthetic diamond compact can be increased and further service life of the polycrystalline diamond compact can prolonged.
Description
Technical field
The utility model relates to the super-hard compound material that oil, natural gas and geological drilling are used, specifically the matrix of composite polycrystal-diamond.
Background technology
Along with the development of oil, natural gas and geological drilling technology, oil, natural gas and geological drilling also require more and more higher to boring tool.Composite polycrystal-diamond is by diadust and binder material and the hard alloy layer super-hard compound material that sintering forms under HTHP.Because diamond compact has high hardness and abrasion resistance and heat stability, composite polycrystal-diamond becomes the critical material of oil, natural gas and geological drilling tools.
Composite polycrystal-diamond is applied on the drill bit of oil, natural gas and geological drilling, be the key components of drill bit, and the quality of its performance has directly determined the collection of data in the efficiency, drilling process of oil gas address probing etc.Therefore the combination property that how to improve composite polycrystal-diamond just becomes the main R&D direction of research petroleum drilling tooth, and the carbide interface structure of optimizing plays very large effect to improving the combination property of composite polycrystal-diamond.Because diamond has the very low coefficient of expansion, carbide alloy has the relatively high coefficient of expansion, in the high temperature building-up process of composite polycrystal-diamond, have and heat up fast and temperature-fall period, so on the interface of polycrystalline diamond layer and hard alloy layer combination with regard to macro-stress very large under residual, this stress has harm, be easy to cause polycrystalline diamond layer and hard alloy layer layering, the residual stress therefore how reducing between polycrystalline diamond layer and carbide alloy bed boundary becomes people's question of common concern.
Summary of the invention
The utility model object is to overcome composite polycrystal-diamond and when HTHP is synthetic, remains in the stress of polycrystalline diamond layer and carbide alloy bed boundary, and then improves a kind of constitutionally stable composite polycrystal-diamond matrix of the bond strength of polycrystalline diamond layer and carbide alloy bed boundary.
The purpose of this utility model is achieved through the following technical solutions: the utility model discloses a kind of column shaped carbide alloy matrix for composite polycrystal-diamond, it is characterized in that: the upper surface of matrix is provided with one or more projections, each projection is for being concentric annular projection 4,5; There is one or more ring-types sinking groove 2 spaced apart at edge, upper surface 3, between described sinking groove, is face symmetry or Central Symmetry, looping groove between adjacent two projections.
Further, the column shaped carbide alloy matrix for composite polycrystal-diamond, is characterized in that: between adjacent two projections, be the smooth annular groove of arc transition, edge, described upper surface 3 looping platforms.
Further again, the column shaped carbide alloy matrix for composite polycrystal-diamond, is characterized in that: the quantity of described sinking groove 2 is two, is face symmetry or Central Symmetry; Three, be centrosymmetric; Or four, be in the face of old or Central Symmetry.
Further again, column shaped carbide alloy matrix for composite polycrystal-diamond, it is characterized in that: arc transition is all arranged at the bottom of described annular groove, described sinking groove 2 also all has arc transition with the joint portion at edge, upper surface, and also there is arc transition bottom and the joint portion between adjacent protrusion of described sinking groove.
The bonded area that so can increase polycrystalline diamond layer and hard alloy layer in composite polycrystal-diamond, is also beneficial to adamantine mobility.
So can increase the thickness of local polycrystalline diamond layer in composite polycrystal-diamond, improve the life-span of composite polycrystal-diamond.
