Abstract
The utility model relates to a tooth surface and diamond combined sheet, comprising a diamond layer and a hard alloy matrix layer. The end surface of the diamond layer is provided with a curved surface tooth arraying structure, and the curved surface tooth arraying structure comprises teeth grooves between the teeth. The drill bit which is made of the utility model has the advantages of obviously improving the rock breaking efficiency of the drill tooth and greatly increasing the drilling speed of the drill bit.
Description
Technical field
The utility model belongs to the superhard material field, is specifically related to a kind of Diamond-Carbide Comnosite, is called for short diamond compact.
Background technology
Diamond compact is after diamond dust is added certain binding material and hard alloy substrate and fits together, on the special diamond hydraulic press under the high pressure high temperature condition sintering make.It is made of one deck polycrystalline diamond layer and hard alloy substrate layer.Because polycrystalline diamond layer hardness height, abrasion resistance are good, add the excellent toughness and the solderability of hard alloy substrate, make it in oil drilling, geological drilling and coal mining are used, become fitst water, the most rising at present bit drills tooth.
The diamond end face of diamond compact brill tooth all is plane, sphere or arcwall face at present.Bore tooth with these diamond compacts and make drill bit, because the origin of force of brill tooth is little, the rate of penetration of drill bit is than very fast at the drilling well initial stage.Be worn down to the plane along with boring increment face working position by plane, sphere or arc surface, the contact area of boring tooth and rock is also strengthening, and it is more and more blunt to show as drill bit, and the rate of penetration of drill bit is slack-off.
Summary of the invention
The purpose of this utility model is the problems referred to above at existing diamond compact existence, and a kind of flank of tooth diamond compact that can improve efficiency of breaking rock, improve the rate of penetration of drill bit is provided.
The purpose of this utility model is achieved in that the utility model comprises diamond layer and hard alloy substrate layer, is provided with curved surface toothrow structure at the end face of described diamond layer, and curved surface toothrow structure comprises the groove of tooth and between cog.
Technique effect of the present utility model is: the utility model should make the groove direction of the curved surface toothrow structure on the diamond layer end face point to rock face when the welding diamond compact bit, curved surface toothrow structure in boring rock work on the diamond layer end face becomes the working position, one row's " tooth " of curved surface toothrow structure becomes cutting edge, the rock ability of cutting of this toothrow and effect will far surpass existing anodontia diamond compact and bore tooth, and this effect can remain to whole brill tooth inefficacy always, so drill bit that adopts diamond compact of the present utility model to make, can obviously improve the efficiency of breaking rock that bores tooth, improve the rate of penetration of drill bit greatly.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, embodiment one is combined by diamond layer 1 and hard alloy substrate layer 2, the end face of diamond layer 1 is combined by curved surface toothrow structure and plane 4, its mean camber toothrow structure accounts for 1/2nd of diamond layer 1 end face diameter, the diamond layer end face of this combination shape, finish drilling work with curved surface toothrow structure, and planar section helps arranging of rock bits, the curved surface toothrow structure of embodiment one mainly is that the groove 3 by tooth 3 and between cog is formed by connecting, the little inclined-plane 6 that the joint on each groove 3 and the plane 4 of diamond layer 1 end face is provided with 45 ° of inclination angles as shown in Figure 4, little inclined-plane 6 helps chip removal, and is very important.The inclination angle on above-mentioned little inclined-plane is generally between 10 °-45 °.
As shown in Figure 5, embodiment two is with the difference of embodiment one: the tooth 3 of embodiment one mean camber toothrow structure and the cross sectional shape of groove 5 are triangle, and the cross sectional shape of the tooth 7 of embodiment two mean camber toothrow structures and groove is a waveform.
The end face of diamond layer is combined among embodiment one and the embodiment two, is combined by curved surface toothrow structure and plane.In the combined diamond compact of this diamond layer end face, curved surface toothrow structure generally accounts for sixth to two/one of diamond layer end face diameter from the edge.
The utility model also can be provided with curved surface toothrow structure at the whole end face of diamond layer, for example embodiment three to embodiment six, embodiment three to embodiment six difference between them only is that the shape of the tooth of curved surface toothrow structure and groove is different: as shown in Figure 6, the tooth 8 of embodiment three mean camber toothrow structures and groove be shaped as triangle; As shown in Figure 7, the tooth 9 of embodiment four mean camber toothrow structures and groove be shaped as trapezoidal; As shown in Figure 8, the tooth 10 of embodiment five mean camber toothrow structures and groove is shaped as waveform; As shown in Figure 9, the tooth 11 of embodiment six mean camber toothrow structures and groove be shaped as square.
As mentioned above, the tooth of the utility model mean camber toothrow structure or the cross sectional shape of groove can adopt triangle trapezoidal or square or circular arc or waveform, or other shape, the shape of tooth and groove can be identical, also can be different, the shape of each tooth can be identical or inequality in the same diamond compact, and the shape of each groove also can be identical or inequality, can be made up by above-mentioned two or more shape.
The utility model can adopt the tooth-shape structure of different shape on the bonding surface of diamond layer and hard alloy substrate layer, the direction of the groove of the tooth-shape structure of this inner boundary is preferably vertical with the groove direction of the curved surface toothrow structure of diamond layer end face.
