Abstract
The utility model relates to the ball tooth technology field, especially relates to a gradient structure diamond-cemented carbide composite ball tooth. The utility model is characterized in that the ball tooth is constituted by a ball tooth surface layer, a ball tooth middle gradient structure layer, and a ball tooth bottom layer sequentially; the ball tooth middle gradient structure layer has three to five layers; the ball tooth surface layer is a polycrystalline diamond PCD member; the ball tooth middle gradient structure layer is a member composited by polycrystalline diamond PCD and cobalt; the ball tooth bottom layer is a YG15cemented carbide matrix member. By using the ball tooth, the drill bit used in the hard rock stratum provided with the strong abrasiveness has advantages of long service lifetime, high efficiency, and low costs.
Description
Technical field
The utility model relates to ball tooth technical field, especially a kind of gradient-structure diamond-carbide alloy composite balls tooth.
Background technology
Hard alloy spherical-teeth is a kind of detritus material that is widely used in down-the-hole hammer drill head, rock bit, bore bit and major diameter roller cutter bit etc.; Mainly be to impact and roll extrusion mode fractured rock; Impact or the microshock loading owing to have; In creeping into, during firmly to firm hard formation, can raise the efficiency 5-10 doubly than pure rotary drilling mode, so be widely used in mining engineering, geological drilling, hydrological well probing, oil and gas well drilling and the drilling well of heavy caliber engineering.But because the abrasion resistance lower (with respect to diamond) of carbide alloy; When in the rock hard, that abrasion is strong, creeping into; Carbide mosaic tooth on the drill bit is often by wearing and tearing prematurely; Particularly the wearing and tearing of drill bit peripheral teeth are even more serious, and this not only can reduce penetration rate, and the wearing and tearing of peripheral teeth also can make bore diameter diminish.Behind the bit wear, must drill bit together with drilling tool in the hole face of land be proposed, with the drill bit that drill bit is carried out reconditioning or more renews.The frequent brill of carrying will certainly increase subsidiary operation time, and is particularly like this when boring is dark, reduces the rotating hours.In addition, newly descend the drill bit in the hand-hole also will the boring of undergauge be extended to required size, this is spended time not only, has increased the meaningless wearing and tearing of green bit.People such as the U.S. famous probing expert W.C.Maurer add up and point out nineteen ninety, and in the deep-well construction, nearly 70% time spends in the process of creeping into and making a trip.In the hard formation area, bit cost accounts for more than 50% of whole deep shaft sinking expense.It is thus clear that the abrasion resistance deficiency is the main cause that the current carbide drill life-span is short, drilling efficiency is low.
Summary of the invention
In order to overcome the deficiency of present hard alloy spherical-teeth; The utility model provides a kind of not only wear-resisting but also shock resistance gradient-structure diamond-carbide alloy composite balls tooth; Substitute conventional hard alloy spherical-teeth, the hard alloy spherical-teeth bit life is short in hard, strong abrasiveness rock stratum, efficient is low, the high problem of cost to solve.
The utility model solves the technical scheme that its technical problem adopted: 1, a kind of gradient-structure diamond-carbide alloy composite balls tooth is characterized in that: compound institute forms by gradient layer and ball tooth bottom in the middle of ball tooth top layer, the ball tooth.
According to above-mentioned described a kind of gradient-structure diamond-carbide alloy composite balls tooth, it is characterized in that: gradient layer has the 3-5 layer in the middle of the ball tooth.
According to above-mentioned described a kind of gradient-structure diamond-carbide alloy composite balls tooth, it is characterized in that: ball tooth top layer is a kind of polycrystalline diamond PCD spare;
According to above-mentioned described a kind of gradient-structure diamond-carbide alloy composite balls tooth, it is characterized in that: gradient layer is a kind of polycrystalline diamond PCD and cobalt composite members in the middle of the ball tooth;
According to above-mentioned described a kind of gradient-structure diamond-carbide alloy composite balls tooth, it is characterized in that: ball tooth bottom is a kind of YG15 hard alloy substrate spare.
The beneficial effect of the utility model is that bit life is long in hard, strong abrasiveness rock stratum, efficient is high, cost is low.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
