The technical problems to be solved in the utility model is: provide a kind of polycrystalline diamond compact bit, improves the intensity of drill bit, simultaneously cost-saving, prevents bit wear, improves the service life of drill bit.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of polycrystalline diamond compact bit, comprise drillstock, drill neck and apex point, described drill neck two ends respectively one connect drillstock and apex point, described drill neck is provided with helical form chip area, described apex point is provided with two cutting edges, the angle of described apex point is 145 °, the material of described drill neck is polycrystalline diamond, the surface of described drill neck is applied with some diamond frosted particles, described drillstock is cross section is cylindrical double-decker, it comprises the hard alloy layer of inner side and coated TiAlN coating outside it.
Preferably, polycrystalline diamond layer is provided with between described hard alloy layer and outer TiAlN coating.
Preferably, the material of described apex point is polycrystalline diamond.
Preferably, the spiral angle of described chip area is 30 °.
Preferably, described drillstock is provided with at least two annular grooves.
Preferably, the end of described drillstock is provided with the chamfering of 45 °.
Relative to prior art, the utility model provides a kind of polycrystalline diamond compact bit, by changing the material of drill neck and being applied with some diamond frosted particles to its surface, substantially increases the intensity of drill neck, prevents drill neck to be out of shape or fracture; Drillstock comprises hard alloy layer and TiAlN coating, ensures the intensity of drillstock while cost-saving, reduces the wear phenomenon of drillstock under the state of extraneous high-strength working; The utility model can ensure the intensity of drill bit, simultaneously cost-saving, improves operating efficiency and the service life of drill bit.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of drill bit preferred embodiment of the present utility model.
[in figure Reference numeral]:
10. drillstock, 20. drill necks, 30. apex points, 40. chip areas, 50. cutting edges, 60. frosted particles, 70. hard alloy layers, 80. TiAlN coating, 90. polycrystalline diamond layers, 100. chamferings.
Detailed description of the invention
For making content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certain the utility model is not limited to this specific embodiment, and the general replacement known by those skilled in the art is also encompassed in protection domain of the present utility model.Secondly, the utility model detailed statement that utilized schematic diagram to carry out, when describing the utility model example in detail, for convenience of explanation, schematic diagram, should in this, as to restriction of the present utility model not according to general ratio partial enlargement.
Above-mentioned and other technical characteristic and beneficial effect, will in conjunction with the embodiments and accompanying drawing 1 drill bit of the present utility model is described in detail.As shown in Figure 1, Fig. 1 is the structural representation of drill bit preferred embodiment of the present utility model.
As shown in Figure 1, the utility model provides a kind of polycrystalline diamond compact bit, comprise drillstock 10, drill neck 20 and apex point 30, drill neck 20 two ends respectively one connect drillstock 10 and apex point 30, drill neck 20 is provided with helical form chip area 40, apex point 30 is provided with two cutting edges 50, the angle of apex point 30 is 145 °, the material of drill neck 20 is polycrystalline diamond, the surface of drill neck 20 is applied with some diamond frosted particles 60, drillstock 20 for cross section be cylindrical double-decker, it comprises the hard alloy layer 70 of inner side and coated TiAlN coating 80 outside it.
For strengthening the intensity of drillstock further, between hard alloy layer 70 and outer TiAlN coating 80, be provided with polycrystalline diamond layer 90; And the material of apex point 30 is polycrystalline diamond.
