Abstract
The utility model provides a diamond bit comprising graphite cylinder, comprising a steel body (10) and a carcass (20) connected with the steel body; said carcass (20) is provided with a work layer (23); said work layer is provided with carcass blocks (30) along the circumferential direction at interval; the carcass comprises a diamond base body (32) and multiple graphite cylinders (34) arranged on the diamond base body in penetrating way. When the diamond bit drills, the graphite cylinders can be abraded quickly such that the contact area between the diamond bit cone and the rock is reduced, and the unit pressure that the cone applies to the rock is increased, and the rock can be broken by the diamond much more easily. The drilling speed of the drill bit is increased, which solves the problem that the drilling speed of the diamond bit on medium hard to hard rock stratigraphic layer is low.
Description
Technical field
The utility model relates to a kind of drill bit, relates in particular to a kind of diamond bit that contains cylinder graphite.
Background technology
At present, diamond bit is in field extensive uses such as municipal road and bridge, building, explorations.Diamond bit generally includes a steel body and a carcass, and carcass is provided with some moles, and the contact surface of mole and object to be processed is its labial surface.Find in the use that diamond bit speed when creeping into is slow, when main cause was to creep into, diamond bit labial surface and rock contact area were big, and it is not enough so that its fragmentation to make that the labial surface of carcass puts on the pressure of rock surface.
The utility model content
The purpose of the utility model provides a kind of diamond bit that contains graphite cylinder, to increase the pressure that the drill bit lip puts on rock, improves the rate of penetration of drill bit.
The utility model provides the diamond bit that contains graphite cylinder; Comprise a steel body and a carcass that is connected in the steel body; Has a working lining on the carcass; Working lining is provided with mole along the compartment of terrain that makes progress in week of carcass, and mole comprises that diamond body and several are arranged in the graphite cylinder in the diamond body.
In the another kind of exemplary embodiment of the utility model, the axially parallel of the bearing of trend of graphite cylinder and diamond bit in the diamond bit, and graphite cylinder is located in the mole equably.
In the working lining of diamond drill bit matrix, inserted graphite cylinder; When creeping into; The graphite cylinder quick abrasion; Thereby the contact area, the labial surface that have reduced diamond bit labial surface and rock impose on, and the pressure of lithologic unit area increases, diamond fractured rock more easily, and the drill bit rate of penetration improves, the slow-footed problem of diamond drilling to the solid rock stratum firmly in having solved.
Description of drawings
Following accompanying drawing is only done schematic illustration and explanation to the utility model, does not limit the scope of the utility model.
Fig. 1 is the structure cross-sectional schematic that contains a kind of exemplary embodiment of diamond bit of graphite cylinder.
Fig. 2 is the floor map of the labial surface of diamond bit shown in Figure 1.
Fig. 3 is that the diamond bit that contains graphite cylinder uses a period of time, the floor map of its its labial surface of work plane wearing and tearing back.
Label declaration
10 steel bodies
20 carcasses
23 working linings
30 moles
32 diamond bodies
324 cavities
34 graphite cylinders.
Hereinafter will be with clear and definite understandable mode, and the accompanying drawings preferred embodiment further specifies above-mentioned characteristic, technical characterictic, advantage and the implementation thereof of diamond bit.
The specific embodiment
Understand for technical characterictic, purpose and effect to utility model have more clearly, contrast the specific embodiment of description of drawings the utility model at present, identical label is represented identical part in each figure.
For making drawing succinct, only schematically shown out the part relevant among each figure with the utility model, they do not represent its practical structures as product.In addition, so that drawing succinctly is convenient to understand, the parts that in some figure, have same structure or function have only schematically illustrated one of them, or have only marked one of them.
In this article, " one " not only representes " only this ", also can represent the situation of " more than ".
Fig. 1 is the structure cross-sectional schematic that contains a kind of exemplary embodiment of diamond bit of graphite cylinder.As shown in the figure, diamond bit comprises a steel body 10 and a carcass 20.Carcass 20 is connected in steel body 10, has a working lining 23 on the carcass 20, and working lining 23 is provided with some moles 30 along the compartment of terrain that makes progress in week of carcass 20.Mole 30 comprises diamond body 32 and some graphite cylinders 34, and graphite cylinder 34 is arranged in the diamond body 32.
Referring to Fig. 3, use above-mentioned diamond bit, when the labial surface of the mole of carcass 20 contacts with rock; The pressure that puts on the diamond bit makes graphite cylinder contact with rock simultaneously with diamond body, after use a period of time, because graphite cylinder hardness is little; The graphite cylinder that contacts with rock on the labial surface cavity 324 occurs prior to diamond body 32 wearing and tearing, makes the effective area of labial surface and rock contact surface reduce; Putting under the identical situation of pressure on the diamond bit; Labial surface can provide bigger pressure to put on the rock, and diamond is fractured rock more easily, improves rate of penetration thus.
Wherein, diamond body 32 can adopt disperse that the metal and the nonmetal carcass of diamond particles are arranged.The diameter of graphite cylinder, arrangement mode and arranging density etc. can be regulated according to actual needs.
In a kind of exemplary embodiment of the diamond bit that contains graphite cylinder, carcass 20 passes through hot pressed sintering in steel body 10.Adopt the processing mode of hot pressed sintering, make the easy mass production of diamond bit, and the steady quality of product, processing technology is simple.
Please consult Fig. 1 and Fig. 2 simultaneously.In the exemplary embodiment of the diamond bit that contains graphite cylinder as depicted in figs. 1 and 2, the bearing of trend of graphite cylinder 34 and the axially parallel of diamond bit, and as shown in Figure 2, graphite cylinder 34 is located in the mole 30 equably.
In this article, " schematically " expression " is served as instance, example or explanation ", should any diagram, the embodiment that be described to " schematically " in this article be interpreted as a kind of preferred or have more the technical scheme of advantage.
The listed a series of detailed description of preceding text only is specifying to the feasibility embodiment of the utility model; They are not the protection domain in order to restriction the utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit done and all should be included within the protection domain of the utility model.
Claims (2)
