The specific embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
Embodiment 1:
The manufacture craft process of the utility model superhard material and metal matrix material body comprises the steps:
Step 1: as shown in Figure 1, make the marmem container, it is shaped as pipe box 2, and the wall thickness range of pipe box is 0.5-5mm usually, and its optimum value is determined according to superhard material cylinder 1 diameter and the solid technological requirement of edge.Under the situation of pipe box 2 inside dimensions, to its processing of finalizing the design than the little 2%-15% of superhard material cylinder 1 overall size.Superhard material cylinder 1 will be inserted in subsequent step in the pipe box 2.
Step 2: as shown in Figure 2, pipe box 2 is expanded the processing of its capacity, i.e. reaming is handled; Mechanical hole reaming under room temperature or low temperature makes the overall size of pipe box 2 inside dimensions greater than superhard material cylinder 1.
Step 3: as shown in Figure 3, earlier superhard material 1 is inserted in the marmem pipe cover 2, be heated proper temperature then, be generally 50-150 ℃, owing to promptly produce after marmem pipe cover 2 is heated and return to original shape, and superhard material 1 stops its necking deformation, causes memorial alloy pipe box 2 to wale superhard material 1 tightly with very big restoring force, forms a marmem container 4 that is installed with superhard material like this.After being installed with marmem container 4 formation of superhard material, be final fitted position with its outer shape grinding, as shown in Figure 4.
Step 4: as shown in Figure 5, the marmem container 4 interference fit edge that is installed with superhard material is solid on metallic matrix 3, and its magnitude of interference is 0.02-0.20mm.A memorial alloy pad 5 has been placed in perforation bottom at metallic matrix 3, with bumper and absorbing shock.Under situation without damping, can not need pad 5, the thickness range of pad 5 is 0.5-5mm, its structure is as shown in Figure 6.
The material of marmem pipe cover 2 is that NiTi bianry alloy or NiTiNb ternary alloy three-partalloy or NiTiCu ternary alloy three-partalloy or Fe-Mn-Si are alloy or Cu base alloy.
Embodiment 2:
Above-mentioned superhard material and metal matrix material complex method can specifically be applied on the oil drilling tool, such as: the application of oil drilling tools stabilizer, as described below:
In oil drilling, be extensive use of drilling tool stabilizer, be used for stablizing drill bit, control well track and the finishing borehole wall, particularly in directional well and horizontal well, the wearability of drilling tool stabilizer is had higher requirement.At present the drilling tool stabilizer that generally uses mainly with Talide as its surperficial wearing layer, generally adopt and on steel matrix, inlay the tungsten carbide cylinder, weld modes such as tungsten carbide slug or built-up welding tungsten carbide.In directional well and horizontal well, because bigger with the contact load of the borehole wall, with the drilling tool stabilizer serious wear of tungsten carbide as wearing layer, the life-span is shorter, and drilling tool stabilizer wearing and tearing back influences the accuracy of hole trajectory control.For the wearability and the service life of improving drilling tool stabilizer, can adopt the above-mentioned method of the utility model on steel matrix, to inlay the dimond synneusis cylinder and replace the tungsten carbide cylinder as its wearing layer, because the wearability of dimond synneusis cylinder is about 90-100 times of the tungsten carbide cylinder, therefore can improve the wearability of drilling tool stabilizer greatly.
As shown in Figure 7, inlay the drilling tool stabilizer structural representation of dimond synneusis cylinder for the utility model.By among the figure as can be known, with an above dimond synneusis cylinder 1 ' with marmem pipe cover 2 parcels after, interference fit is mounted in the perforation on the steel matrix 3 of drilling tool stabilizer, forms surface wear-resistant layer.Fig. 8 is the partial enlarged drawing of A-A section among Fig. 7, can clearly demonstrate an above dimond synneusis cylinder 1 ' on the steel matrix 3 that interference fit is mounted to drilling tool stabilizer, and concrete position relation between the marmem pipe cover 2.
Embodiment 3:
Above-mentioned superhard material and metal matrix material complex can also be applied on the oil drilling tool, such as: drill bit.On the bit body of rock bit or tooth pawl back, gear wheel surface, inlay dimond synneusis cylinder or dimond synneusis tooth, as gauge teeth or deburring tooth, replace the Talide tooth that uses at present, can improve the wearability of drill bit greatly and protect the footpath ability, work to keep the bit diameter and the finishing borehole wall.
Also has another kind of application mode, on the basis of inlaying the Talide tooth at present, after adopting marmem pipe cover shroud ring hard-metal insert post, be mounted in the perforation on gear wheel surface after being full of, because the super-elasticity and the high damping shock absorption characteristic of marmem, the impact stress of the extraneous load of available buffer avoids tooth cracked.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
