Abstract
The utility model relates to a common drill for projects of mines, tunnels and the like, in particular to a polycrystalline diamond enhancement type hard alloy body assorted with a chisel bit, which comprises a hard alloy body. The hard alloy body is an integral structure, two inclined surfaces of the hard alloy body are provided with polycrystalline diamond layers; or the polycrystalline diamond enhancement type hard alloy body comprises a left hard alloy body and a right hard alloy body, a polycrystalline diamond layer is disposed between the left hard alloy body and the right hard alloy body, and the thickness of the polycrystalline diamond layer ranges from 0.1mm to 5.0mm. The polycrystalline diamond enhancement type hard alloy body integrates high wear resistance of polycrystalline diamond with fine impact resistance of hard alloy, increases integral wear resistance on the premise of not reducing impact resistance of original hard alloy, prolongs service time, accelerates rock drilling efficiency of the chisel bit, prolongs service life of the chisel bit, reduces rock drilling cost and construction cost, and then shortens construction period.
Description
Technical field:
The utility model relates to drilling tool commonly used in the engineerings such as a kind of mine, tunnel, is specifically related to a kind of and the matching used polycrystalline diamond enhancement type hard of mono-line bit alloy body.
Background technology:
In the prior art, bore bit is widely used in various mining operations and stonework, bore bit in the market mostly is hard alloy drill, hard alloy drill is divided into sheet carbide bore bit and ball (post) profile of tooth hard alloy drill two big series by its shape, the sheet carbide bore bit is divided into yi word pattern again, three sword types, cross, X type hard alloy drill, mono-line bit is the mine, the rock drilling running stores of using always in the engineerings such as tunnel, mono-line bit is subjected to bigger shock loading and wearing and tearing in the Drilling process, and this just requires the bore bit material must possess higher intensity, toughness and good abrasion resistance.Present mono-line bit mostly is Hardmetal materials, carbide alloy intensity is higher, but its abrasion resistance is relatively poor, the wearing and tearing of carbide alloy mono-line bit are very fast in actual use, application life is short, improved the engineering construction cost virtually, also influence the duration, for addressing this problem, diamond drill bit hardness diamond drill bit appearred, on the market, abrasion resistance all can reach the instructions for use of bore bit, but diamond drill bit costs an arm and a leg, cost is higher, so it is relatively cheap to be badly in need of a kind of cost low price on the market, and intensity and abrasion resistance can satisfy the bore bit of rock drilling needs.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the polycrystalline diamond enhancement type hard alloy body that the utility model provides a kind of mono-line bit to use, it is that the excellent impact resistance of the high-wearing feature of polycrystalline diamond and carbide alloy is merged, under the prerequisite that does not reduce original carbide alloy impact resistance, improved the abrasion resistance of cemented carbide body integral body, prolonged the service time of cemented carbide body, accelerated the rock penetration performance of mono-line bit, improved the application life of mono-line bit, reduced the rock drilling cost, and then reduced construction cost, reduction of erection time.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The polycrystalline diamond enhancement type hard alloy body that a kind of mono-line bit is used, it comprises cemented carbide body, wherein: described cemented carbide body or be overall structure, two inclined-plane is provided with polycrystalline diamond layer 4; Or comprise and left cemented carbide body 1 and right cemented carbide body 3 are provided with polycrystalline diamond layer 2 between left cemented carbide body 1 and the right cemented carbide body 3.
Further, the thickness of described polycrystalline diamond layer 2 and polycrystalline diamond layer 4 is 0.1 ~ 5.0mm.
The beneficial effects of the utility model are:
1, the utility model is that the excellent impact resistance of the high-wearing feature of polycrystalline diamond and carbide alloy is merged, under the prerequisite that does not reduce original carbide alloy impact resistance, improved the abrasion resistance of cemented carbide body integral body, prolonged the service time of cemented carbide body, accelerate the rock penetration performance of mono-line bit, improved the application life of mono-line bit, reduced the rock drilling cost, and then the reduction construction cost, the reduction of erection time.
2, the utility model is simple in structure, and is easy to process, and cost is low, the service efficiency height.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, the polycrystalline diamond enhancement type hard alloy body that a kind of mono-line bit is used, it comprises left cemented carbide body 1 and right cemented carbide body 3, is provided with the thick polycrystalline diamond layer of 2.5mm 2 between left cemented carbide body 1 and the right cemented carbide body 3.
During making, in the middle of two carbide alloy, insert diamond powder and cementing agent, the alloy after the combination is put into cubic hinge press, form through the HTHP sintering.Hot-forming back polycrystalline diamond strengthens carbide alloy body and function line and cuts into Fig. 1, Fig. 2, shape shown in Figure 3.
Embodiment two:
As Fig. 4, Fig. 5, shown in Figure 6, repeat embodiment one, following difference is arranged, cemented carbide body is an overall structure, two inclined-plane is provided with polycrystalline diamond layer 4, and the thickness of polycrystalline diamond layer 4 is 1.0mm, and its preparation method also is that the HTHP sintering forms in cubic hinge press.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
