Description
Technical field
The utility model relates to engineering drilling, mine locating drilling tool accessory field, coal seam, is specifically related to a kind of alloy coated drilling bit.
Background technology
During coal production boring, general use ordinary rigid alloy is as the cutting edge of drill bit, when being applied to coal production digging, supporting, leading to the boring in preventing, drilling depth is slow, efficiency is low, bit consumption is large, labor strength is high, and easily come off in working angles, and diamond bit cost is high, be unsuitable for promoting the use of.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of alloy coated drilling bit.
The utility model is achieved through the following technical solutions: a kind of alloy coated drilling bit, comprises bit body, and the front end of bit body is provided with groove, and cutter head is arranged in groove; The middle part of bit body is provided with sludge groove, and sludge groove is for being symmetrical arranged, and quantity is two; The rear end of bit body is provided with ladder blind hole, and blind hole back segment is internal thread; The end face of described cutter head is inclination cambered surface; Described cutter head is coated with diamond coatings; The front end of described bit body is provided with limbers, and the cross section of the junction of bit body back segment and bit body leading portion is isosceles trapezoid.
As preferably, on cutter head, the thickness of diamond coatings is 0.12 ~ 0.18mm.
The usefulness of this utility model is, the utility model provides a kind of alloy coated drilling bit, improve hardness and the abrasion resistance of cutting edge, there is again good toughness, improve drilling efficiency, reduce the labour intensity of workman, decrease bit consumption, difficult drop-off in the course of work, greatly improves efficiency of construction.Its structure is simple, and strong adaptability, easily operates, and has practicality widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of alloy coated drilling bit;
Fig. 2 is the structural representation of another angle of alloy coated drilling bit;
In figure, 1 bit body, 2 grooves, 3 cutter heads, 4 diamond coatings, 5 limberss, 6 sludge grooves.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides a kind of alloy coated drilling bit, comprises bit body 1, and the front end of bit body 1 is provided with groove 2, and cutter head 3 is arranged in groove 2; The middle part of described bit body 1 is provided with sludge groove 6, and sludge groove 6 is for being symmetrical arranged; The rear end of bit body 1 is provided with ladder blind hole, and blind hole back segment is internal thread; The end face of described cutter head 3 is inclination cambered surface; Described cutter head 3 is coated with diamond coatings 4; The front end of described bit body 1 is provided with limbers 5, and limbers 5 is symmetrically arranged two, and the cross section of the junction of bit body back segment and bit body leading portion is isosceles trapezoid.
In the present embodiment, the quantity of sludge groove 6 is two, and sludge groove is conducive to rock dust and discharges, and reduce and creep into resistance, drill bit is not fragile, increases the service life.Cutter head is overall structure simultaneously, and difficult drop-off in the course of work, increases work efficiency, and on cutter head, the thickness of diamond coatings is 0.12 ~ 0.18mm.In actual use, according to working environment, coating layer thickness can be adjusted in time, to meet different work condition.
Alloy coated drilling bit of the present utility model, improves hardness and the abrasion resistance of cutting edge, has again good toughness, improve drilling efficiency, reduce the labour intensity of workman, decrease bit consumption, difficult drop-off in the course of work, greatly improves efficiency of construction.Its structure is simple, and strong adaptability, easily operates, and has practicality widely.
