Abstract
The utility model discloses a diamond bit who contains potassium steel awl, including the steel body, matrix, mole, the steel body coupling the matrix, the matrix is the loop configuration, the mole spacer ring to set up being in the matrix on, the mole include that diamond base member and a plurality of wear to locate the potassium steel cone in the diamond base member, the setting of potassium steel cone circular cone head protrusion be in mole surface. In this way, the utility model discloses a when diamond bit creeps into, potassium steel cone evagination, thereby the area of contact of diamond bit lip face with the rock has been reduced, the pressure that makes the lip face apply for rock unit area increases, diamond bit is to the pressure increase of rock, and simultaneously, when potassium steel receives impact load, plastic deformation takes place and forms the work hardening phenomenon for the surface, make surface hardness increase substantially, its abrasion resistance reinforcing, change the fractured rock, drill bit drilling speed improves, the problem of medium hard to hard rock stratum diamond drilling speed slow is solved.
Description
Technical field
The utility model relates to drill bit field, particularly relates to a kind of diamond bit containing potassium steel cone.
Background technology
At present, diamond bit is in field extensive uses such as municipal road and bridge, building, explorations, and diamond bit generally includes a steel body and a carcass, and carcass is provided with several moles, and the contact surface of mole and rock is its labial surface.For prior art, diamond bit is creeping into hourly velocity slowly, and when main cause is to creep into, greatly, the pressure making the labial surface of carcass put on rock is not enough to make it broken for diamond bit labial surface and rock contact area.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of diamond bit containing potassium steel cone, and the pressure that can be applied to rock by increasing drill bit lip improves the efficiency of drill bit.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of diamond bit containing potassium steel cone, it is characterized in that, comprise: steel body, carcass, mole, carcass described in described steel body connects, carcass is loop configuration, described mole spacer ring is to being arranged on described mole, described mole comprises diamond body and several are arranged in potassium steel cone in diamond body, and described potassium steel cone conical head is protruded and is arranged on described mole surface.
In the utility model preferred embodiment, described potassium steel cone is evenly distributed in each mole, has 6-10 in each mole.
In the utility model preferred embodiment, the bearing of trend of described potassium steel cone is parallel with the axis of described diamond bit.
In the utility model preferred embodiment, the head of the cone structure of described potassium steel cone protrudes, and is highly 1-5mm.
In the utility model preferred embodiment, described carcass by hot pressed sintering on described steel body.
The beneficial effects of the utility model are: when diamond bit of the present utility model creeps into, potassium steel cone evagination, thus reduce the contact area of diamond bit labial surface and rock, the pressure making labial surface be applied to lithologic unit area increases, diamond bit increases the pressure of rock, simultaneously, when potassium steel is subject to shock loading, there is plastic strain and form work hardening phenomenon in surface, surface hardness is increased substantially, its abrasion resistance strengthens, easier fractured rock, drill bit rate of penetration improves, hard to the slow-footed problem of solid rock stratum diamond drilling in solving.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, 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, wherein:
Fig. 1 is the cross-sectional view of a kind of first preferred embodiment of diamond drill machine containing potassium steel cone of the utility model;
Fig. 2 is the labial surface schematic diagram of shown diamond bit;
In accompanying drawing, the mark of each parts is as follows: 1-steel body, 2-carcass, 3-mole, 4-diamond body, 5-potassium steel cone.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
A kind of diamond bit containing potassium steel cone, it is characterized in that, comprise: steel body 1, carcass 2, mole 3, described steel body 1 connects described carcass 2, carcass 2 is loop configuration, described mole 3 spacer ring is to being arranged on described carcass 2, and described mole 3 comprises diamond body 4 and several are arranged in potassium steel cone 5 in diamond body 4, and described potassium steel cone 5 conical head is protruded and is arranged on described mole 3 surface.
Be different from prior art.
In another embodiment, described potassium steel cone 5 is evenly distributed in each mole 3, has 6-10 in each mole 3.
In another embodiment, the bearing of trend of described potassium steel cone 5 is parallel with the axis of described diamond bit.
In another embodiment, the head of the cone structure of described potassium steel cone 5 protrudes, and is highly 1-5mm.
In another embodiment, described carcass 2 on described steel body, makes the easy mass production of diamond bit by hot pressed sintering, and the steady quality of product, processing technology is simple.
Utility model works principle: use above-mentioned diamond bit, when labial surface and the rock contact of the mole of carcass, due to potassium steel cone evagination, its first with rock contact, effectively reduce the contact area of diamond bit labial surface and rock when drill bit creeps into, the pressure making labial surface be applied to lithologic unit area increases, diamond bit increases the pressure of rock, simultaneously, when potassium steel is subject to shock loading, there is plastic strain thus form work hardening phenomenon in surface, make potassium steel bore surface hardness to increase substantially, abrasion resistance strengthens, easier fractured rock, drill bit rate of penetration improves, hard to the slow-footed problem of solid rock stratum diamond drilling in solving.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
