Abstract
The invention relates to the field of mining devices, in particular to a detachable drill bit. The detachable drill bit adopts modular design, the integrated drill bit is divided into a drill blade, a drill shoulder and a drillstock which are detachable, the drill blade, the drill shoulder and the drillstock can be individually replaced when one portion is damaged, a standby drill blade is arranged in the internal space of the drillstock, and the detachable drill bit is more convenient to use. The drill bit is modular, and the mining cost is reduced. The drill bit can be detached into several portions and is convenient to use. A standby drill bit is provided so that the mining devices can work continuously. The cutting area is enlarged, and mining efficiency is improved.
Description
Technical field
The present invention relates to winning equipment field, be specially demountable bit.
Background technology
In winning equipment, drill bit is very important assembly, and drill bit is the cutter on brill, drilling machine, rig.Hole can be caused on workpiece or rock.Existing drill bit mainly comprises fluted drill, chit drill, depth drill, reamer, centre drill, core drill etc.
Dig pit operation time, drill bit, around vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is destroyed and smashes to ravel 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 whole process of digging pit.
Drill bit generally all adopts carbide alloy, because the multiple copper foil plate of epoxy glass fabric is fast especially to the wearing and tearing of cutter.So-called carbide alloy take tungsten-carbide powder as matrix, makes cementing agent form through pressurization, sintering with cobalt powder.Usually containing tungsten carbide 94%, containing cobalt 6%.Because its hardness is very high, very wear-resisting, there is some strength, be suitable for high-speed cutting.But poor toughness, is highly brittle, in order to improve the performance of carbide alloy, the ultrahard titanium carbide (TIC) of some employings chemical vapor deposition one deck 5 ~ 7 microns on carbonized matrix or titanium nitride (TIN), make it have higher hardness.Some ion implantation techniques, inject the certain degree of depth of its matrix by titanium, nitrogen and carbon, not only increase hardness and intensity and these inject compositions and can also move to the interior when drill bit is refaced.What also have generates one deck diamond film with physical method at drill bit top, greatly improves the hardness and wear resistance of drill bit.The hardness of carbide alloy and intensity, not only relevant with the proportioning of cobalt with tungsten carbide, also relevant with the particle of powder.The carbide drill of ultra-fine particles, the average-size of its tungsten carbide phase crystal grain is below 1 micron.This drill bit, not only hardness is high but also resistance to compression and flexural strength all improve.Welding handle structure is adopted in order to save the many drill bits of cost, drill bit is originally entirety is all carbide alloy, the drillstock at rear portion have employed stainless steel, and cost declines still owing to adopting its dynamic concentricity of different materials not as good as solid carbide drill greatly, especially in minor diameter.
Present drill bit is all one, and when the blade of drill bit damages or weares and teares, drill bit has substantially just been scrapped, and this situation causes the great wasting of resources, also for mining activity adds many costs.
