Description
Technical field
The present invention relates to winning equipment field, specially demountable bit.
Background technology
In winning equipment, drill bit is critically important component, and drill bit is brill, drilling machine, the cutter on drilling machine.Can be in workpiece
Or hole is caused on rock.Existing drill bit mainly includes fluted drill, chit drill, depth drill, reamer, centre drill, core drill etc..
Dig pit operation when, drill bit rotates around vertical shaft, while moving axially.Moment of torsion and responsive to axial force of the soil in drill bit
Under be cut, be destroyed under the extruding of working-blade and centrifugal action and smash and ravel, formed native stream and press to crater wall, while edge
Page elevator is to earth's surface.It is complete because centrifugal action hack is thrown around hole when native stream is moved at no crater wall stop
Into whole process of digging pit.
Drill bit typically all uses hard alloy, because multiple abrasion of the copper foil plate to cutter of epoxy glass fabric is especially fast.It is so-called
Hard alloy be using tungsten-carbide powder as matrix, with cobalt powder make binding agent it is pressurized, sintering form.Generally contain tungsten carbide 94%, contain
Cobalt 6%.It is extremely abrasive because its hardness is very high, there is some strength, suitable for high-speed cutting.But poor toughness, it is highly brittle, in order to improve
The performance of hard alloy, the ultrahard titanium carbide of some uses 5~7 microns of chemical vapor deposition one layer on carbonized matrix（TIC）
Or titanium nitride（TIN）, make it have higher hardness.Some use ion implantation techniques, its matrix one is injected by titanium, nitrogen and carbon
Fixed depth, not only increases hardness and intensity and these injection compositions can also move to the interior when drill bit is refaced.Also use thing
Reason method generates one layer of diamond film at the top of drill bit, greatly improves the hardness and wear resistance of drill bit.Hard alloy it is hard
Degree and intensity, it is not only relevant with the proportioning of cobalt with tungsten carbide, it is also relevant with the particle of powder.The carbide drill of ultra-fine particles
Head, 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 bending strength
All improve.In order to save many drill bits of cost using welding handle structure, drill bit originally is that entirety is all hard alloy, rear portion
Drillstock employ stainless steel, cost is greatly reduced but is due to hard not as good as overall using its dynamic concentricity of different materials
Matter alloy bit, especially in terms of minor diameter.
Present drill bit is all integral, and when the blade of drill bit is damaged or worn and torn, drill bit is eliminated substantially, this
Situation causes the great wasting of resources, also adds many costs for mining activity.
