Abstract
The utility model relates to a diamond bit with concave-convex labial surfaces, which includes a steel body (12) and a tire casing (11) formed on the steel body, wherein the tire casing is provided with at least two groups of labial surfaces; each group of labial surface includes a lug boss (14) and a groove (13) which are arranged in the axial direction of the diamond bit; and the lug bosses and the grooves on the tire casing are alternately and uniformly fixed at the top of the steel body. The diamond bit provided by the utility model reduces the contact area of the labial surfaces and the rock, solves the problem that integral and hard stratums cost more time for the diamond bit to drill, and the diamond bit has high drilling speed, stable product quality, simple processing technology and high production efficiency, and can be widely used for drilling the integral and hard stratums.
Description
Technical field
The utility model relates to a kind of diamond bit, particularly a kind of diamond bit with concavo-convex labial surface, and this drill bit can be widely used in creeping into of more complete firm hard formation.
Background technology
At present; Diamond bit is in field extensive uses such as municipal road and bridge, building, geological prospectings; In the prior art, diamond bit speed when firm hard formation creeps into is slower, when main cause is to creep into; Diamond bit labial surface and rock contact area are big, and drill bit lip diamond puts on the insufficient pressure of rock with effective fractured rock.
The utility model content
The purpose of the utility model provides a kind of diamond bit with concavo-convex labial surface, and when this drill bit was worked, under the situation of guaranteed strength, the carcass labial surface of its drill bit and the contact area of rock were little, make drill bit fractured rock effectively, improves rate of penetration.
The utility model provides a kind of diamond bit with concavo-convex labial surface; Comprise a steel body and take shape in the carcass on the steel body; Carcass has at least two group labial surfaces; Each is organized labial surface and comprises a boss and groove that axially is provided with along diamond bit, and these boss on the carcass and groove replace and be installed in equably the top of steel body.
In other exemplary embodiment of the diamond bit with concavo-convex labial surface, can have three groups of said labial surfaces on the carcass; Perhaps, in each group labial surface, the boss end face of boss is higher than the groove end face of groove, and for example, the boss end face is higher than groove end face 2mm.
The utility model has reduced the contact area of labial surface and rock, has increased the pressure that drill bit lip unit area puts on rock, and the diamond that makes the diamond drill bit matrix labial surface is fractured rock effectively; Improved the rate of penetration of diamond bit; Solve the slow problem of rate of penetration in the more complete firm hard formation, provide a kind of rate of penetration fast, constant product quality; Processing technology is simple, the diamond bit that rate of penetration is high.
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 with concavo-convex labial surface.

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 or structural similarity but the identical parts of function 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.
As depicted in figs. 1 and 2; Diamond bit comprises a steel body 12 and takes shape in the carcass 11 on the steel body 12; In the illustrated embodiment; Have three groups of labial surfaces on the carcass 11, every group of labial surface comprise along diamond bit a boss 14 and a groove 13 axially be set, and all boss 14 and groove 13 alternately evenly are installed in the top of rigid body 12 on the carcass 11.Adopt such structure can to reduce the contact area of the labial surface and the rock of carcass, increased the pressure that drill bit lip unit area puts on rock, the diamond that makes the diamond bit lip is fractured rock more effectively.
Though in exemplary embodiment illustrated in figures 1 and 2; Have three groups of labial surfaces on the carcass 11; But it will be appreciated by those skilled in the art that; The group number of labial surface can be different with the overall dimensions of drill bit, the geological conditions of drill bit use or the material of drill bit etc., also can be two groups, four groups or more groups like labial surface.
In a kind of exemplary embodiment of the utility model, each organizes groove end face 132 height of the boss end face 142 of boss 14 than groove 13, the pressure that puts on rock in the time of can further strengthening the drill bit lip like this and begin to contact with rock.Through test, when boss end face 142 is higher than groove end face 2mm, both can guarantee drilling effect preferably, can guarantee that also drill bit has enough intensity.The carcass 11 and the steel body 12 of the utility model can adopt Thermocompressed sintering and forming.
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.
