Abstract
The utility model relates to a drill with layered self-sharpening concentric round sharp teeth, which comprises a steel body, a connecting layer and a working layer, wherein the working layer is fixed on the steel body through the connecting layer and consists of a plurality of sharp tooth forming layers and a plurality of groove forming layers, the sharp tooth forming layers and the groove forming layers are distributed at intervals and are concentric, and the upper parts of the sharp tooth forming layers and the groove forming layers are respectively connected with the connecting layer. With the adoption of the sandwich-type drill structure, sharp teeth and grooves can be automatically formed in the well drilling process when the drill contacts with rock stratum and disappear until the working layer of the drill is used up; and the formation of the sharp teeth and the grooves ensures the drill to be sharper, thereby not only greatly improving the drilling efficiency, but also enlarging the adaptation range of the drill to the stratum, preventing the well from being inclined and improving the well drilling quality.
Description
Technical field
The utility model relates to a kind of layer-stepping from grinding sword concentric circles pointed tooth drill bit.
Background technology
Diamond-impregnated bit is a kind of of paramount importance instrument in the modern diamond probing technology; The important indicator of weighing the drill quality quality is exactly drilling life of bit and creeps into timeliness, particularly creeps into the raising of timeliness, can significantly speed up the work; Save labour cost, reduce energy consumption.In the face of soft or hard is interlocked, Protean rock stratum, any diamond-impregnated bit is not omnipotent; Can not satisfy the demand that creep into all rock stratum, often because the incompatible reason of drill bit and stratum causes drilling efficiency low; That have even drill bit " skidding " phenomenon of drilling depth not fully occurs, cause the probing workman to repeat to make a trip, more bit change; Not only waste a large amount of manpower and materials, also significantly increase working strength of workers.It is fast to design a kind of rate of penetration, long service life, and the wide spectrum drill bit of wide accommodation then is the target that people pursue always.
Summary of the invention
The purpose of the utility model just provides that a kind of rate of penetration is fast, the layer-stepping of long service life, wide accommodation is from grinding sword concentric circles pointed tooth drill bit.
The layer-stepping of the utility model is from grinding sword concentric circles pointed tooth drill bit; Comprise steel body, articulamentum and working lining; Working lining is fixed on the steel body through articulamentum, and working lining is made up of a plurality of sharp-tooth shaped stratification and a plurality of channel shaped stratification, and sharp-tooth shaped stratification and channel shaped stratification are spaced apart; The sharp-tooth shaped stratification is concentric with the channel shaped stratification; The sharp-tooth shaped stratification is better by abrasion resistance, diamond concentration is higher, the diamond quality better material is formed, and the channel shaped stratification is relatively poor by abrasion resistance, diamond concentration is lower or not diamantiferous material is formed, and sharp-tooth shaped stratification, the cambial top of groove all link to each other with articulamentum.
The layer-stepping of the utility model is from the advantage that grinds sword concentric circles pointed tooth drill bit: adopt the sandwich style drill bit structure, can make drill bit with boring procedure that the rock stratum contact in formation pointed tooth and groove automatically, exhaust until the drill bit working lining; This pointed tooth and groove just can disappear, and the formation of this pointed tooth and groove makes drill bit become sharper; Not only can significantly improve drilling efficiency; Also can enlarge the accommodation on drill bit and stratum, prevent hole deviation, improve drilling quality.

The specific embodiment
A kind of layer-stepping is from grinding sword concentric circles pointed tooth drill bit; Comprise steel body 4, articulamentum 3 and working lining; Working lining is fixed on the steel body 4 through articulamentum 3, and working lining is made up of with a plurality of channel shaped stratification 2 a plurality of sharp-tooth shaped stratification 1, and sharp-tooth shaped stratification 1 is spaced apart with channel shaped stratification 2; Sharp-tooth shaped stratification 1 is concentric with channel shaped stratification 2, and the top of sharp-tooth shaped stratification 1, channel shaped stratification 2 all links to each other with articulamentum 3.
Claims (2)
1. a layer-stepping is from grinding sword concentric circles pointed tooth drill bit; Comprise steel body (4), articulamentum (3) and working lining; It is characterized in that: working lining is fixed on the steel body (4) through articulamentum (3); Working lining is made up of a plurality of sharp-tooth shaped stratification (1) and a plurality of channel shaped stratification (2), and sharp-tooth shaped stratification (1) is spaced apart with channel shaped stratification (2), and the top of sharp-tooth shaped stratification (1), channel shaped stratification (2) all links to each other with articulamentum 3.
