Description

A kind of diamond bit
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of diamond bit.
Background technology
Cutter on brill, drilling machine, drilling machine, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
Diamond bit is widely used in metal material, stone material or the hard brittle material such as concrete, geological prospecting boring field, but diamond bit drilling effect of the prior art is undesirable, creep into timeliness not high, the service life of drill bit is not long, and diamond broken teeth, the phenomenon falling tooth happen occasionally.
Utility model content
It is undesirable that the technical problems to be solved in the utility model is to solve diamond bit boring, and service life is short.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of diamond bit, by drillstock, drill body and apex point three part connect and compose, it is characterized in that: one end of described drill body is connected with drillstock, described drill body and drillstock are monolithic molding; The other end of described drill body is connected with apex point, and described apex point and drill body are monolithic molding; The structure of described drill body by two ends be the drill body head portion of the ∞ font body of straight end face and cylinder drill body body on the same axis monolithic molding form; Described drill body head portion is provided with horizontally disposed S shape bite along ∞ font position, and described S shape bite and drill body head portion are monolithic molding, and described S shape bite blade and described drill body head portion level angle are 30 ~ 45 °; The structure of described drillstock is elongate cylinder body structure, in one end of drillstock, near end position, is provided with positioning groove.
Further, described apex point leading section is provided with front bite, and between described bite and drill bit axis, angle is 15 ~ 30 °.
Further, the structure of described apex point is the cone that there is helical structure on surface, and the tapering of cone is 15 ~ 30 °, and the cone of cone is high is 5 ~ 10cm.
Further, described drill body head portion also includes two groove for cuttings, described groove for cuttings extends to bottom from the start-up portion in drill body head portion in a helical pattern, on arbitrary cross section in drill body head portion, groove for cuttings is all positioned at position diametrically opposed to each other on drill body head facial planes, and drill body head portion is divided into four parts by described two groove for cuttings uniformly.
Further, described positioning groove is the groove of the rectangular structure offered along cylinder drillstock periphery.
Further, described drillstock front and back end is provided with protective jacket, the structure of described protective jacket is round pie.
The beneficial effects of the utility model are as follows:
1, front bite, these two cuttves of S shape bite and chip discharging structure effectively combine by drill bit of the present utility model, realize twin-stage boring, once-forming, and chip removal is unobstructed, realize the smooth of boring cutting face, increase the service life of drill bit;
2, drill bit of the present utility model is provided with two groove for cuttings in drill body head portion, described two groove for cuttings extend to bottom from front end in a helical pattern, along on arbitrary cross section in drill body head portion, groove for cuttings is all positioned at position diametrically opposed to each other on drill body head facial planes, the groove for cuttings of this symmetric figure, and row's bevel is long-pending large, it is fast that row cuts speed, not easily causes broken accumulation of cutting;
3, have the cuboid groove offered along cylinder drillstock periphery outside drillstock of the present utility model, such groove design serves fastening effect, Embedded drillstock, effectively can prevent drill bit landing from install machinery;
4, apex point of the present utility model adopts surface to have the conical structure of helical structure, is drilling through in the process of hole like this, reduces stress surface, and increase borehole strength, be conducive to the automatic entrance-exit in working angles, stock-removing efficiency will improve greatly;
5, drillstock of the present utility model is installed the protective jacket of round pie, avoided drill bit to hurt the surface of hand and processing work.
