Abstract
A novel diamond drill bit comprises a drill bit body, diamond permanent teeth are arranged on the end surface of the drill bit body, hard alloy permanent teeth are further arranged on the end surface of the drill bit body, and the hard alloy permanent teeth and the diamond permanent teeth are distributed at intervals. In the utility model, the hard alloy permanent teeth and the diamond permanent teeth are distributed on the end surface of the drill bit body at intervals, thus meeting the demand for rotary drilling, being high in strength of the drill bit and longer in service life, and improving the rotary drilling efficiency.
Description
Technical field
The utility model relates to a kind of reamer, is specially a kind of novel diamond bit.
Background technology
Along with the development of society, people increase resource requirement day by day, and the particularly aggravation of world energy sources crisis in recent years makes the fast development of drilling industry.
It is advanced drilling method that the Continental Science deep drilling adopts impact rotating to creep into, and it obviously improves the requirement of drill bit.But because the ballistic work of Hydro-efflux Hammer is bigger, 100J or bigger is arranged all generally in this method, have higher requirement for bit performance, it not only will bear the effect of the pressure of the drill, the effect of the power that also will withstand shocks simultaneously.If in order to improve rate of penetration, the hardness of drill bit is lower slightly wicked, hard carcass on the low side in generally selecting for use, but in hard drill bit can only adapt to rotary drilling, impact rotating creeps into that drill bit is consumed is too fast.Hard matrix drill bits mole avalanche phenomenon can occur under the effect of impact force, drilling efficiency can be not high yet, therefore needs a kind of novel drill bit of design.
The utility model content
The technical problem that the utility model solved provides a kind of novel diamond bit, and its drill bit intensity is high, and application life is longer, has improved rotary drilling efficient, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of novel diamond bit comprises that end face is provided with the drill body of diamond permanent tooth, is that with the remarkable distinguishing characteristics of traditional diamond bit the end face of said drill body also is provided with the carbide alloy permanent tooth.
As a kind of improvement, said diamond permanent tooth annular array is installed on the end face of said drill body.
As a kind of further improvement, said carbide alloy permanent tooth annular array is installed on the end face of said drill body.
As a kind of further improvement, said carbide alloy permanent tooth and diamond permanent tooth are intervally arranged.
The utility model is in order better to adapt to rotary drilling; The Hardness Design of drill body is between HRC35~38, simultaneously, in drill body, adds the thicker needle-like carbide alloy of people regularly; On the end face of drill body, form the carbide alloy permanent tooth, process diamond bit.Diamond permanent tooth fractured rock is main in creeping into, and the carbide alloy permanent tooth bears the part impact force, the hard high characteristics of carcass drilling efficiency in the performance.
Owing to adopted above structure, the utlity model has following beneficial effect:
The drill body end face of the utility model be intervally arranged diamond permanent tooth and carbide alloy permanent tooth have satisfied the requirement of rotary drilling, and its drill bit intensity is high, and application life is longer, has improved rotary drilling efficient.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. drill body, 2. diamond permanent tooth, 3. carbide alloy permanent tooth.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of novel diamond bit comprises that end face is provided with the drill body 1 of diamond permanent tooth 2; Said diamond permanent tooth 2 annular arrays are installed on the end face of said drill body 1; Be that with the remarkable distinguishing characteristics of traditional diamond bit the end face of said drill body 1 also is provided with carbide alloy permanent tooth 3, said carbide alloy permanent tooth 3 annular arrays are installed on the end face of said drill body 1; In the present embodiment, said carbide alloy permanent tooth 3 is intervally arranged with diamond permanent tooth 2.
In the present embodiment; In order better to adapt to rotary drilling, the Hardness Design of drill body 1 is HRC36, simultaneously; In drill body 1, add the thicker needle-like carbide alloy of people regularly; On the end face of drill body 1, form carbide alloy permanent tooth 3, carbide alloy permanent tooth 3 is intervally arranged with the diamond permanent tooth 2 of drill body 1 end face, processes diamond bit.Diamond permanent tooth 2 fractured rocks are main in creeping into, and carbide alloy permanent tooth 3 bears the part impact force, the hard high characteristics of carcass drilling efficiency in the performance.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (4)
1. novel diamond bit, comprise that end face is provided with the drill body of diamond permanent tooth, is characterized in that: the end face of said drill body also is provided with the carbide alloy permanent tooth.
