Description
Technical field
This utility model is related to diamond bit, the impregnated honeybee of a kind of ceramic base hot pressing using especially for slipping formation
Nest body diamond drill bit, belongs to tool equipment technical field used for geological prospecting.
Background technology
In the geological drilling of slipping formation, cannot be from sharp, gold after the diamond particles blunt of conventional PCD drill top layer
After hard rock particle detachment, tyre body abrasion is difficult, and lower floor's diamond particles cannot go out sword, lead to carcass and rock in drilling process to rub
Wipe it is impossible to effective quarter takes rock, drilling efficiency is extremely low, or even skidding.Just currently for the diamond of slipping formation
For drill bit, diamond utilization rate is low, and bit life is short, has a strong impact on geological prospecting work efficiency.
Content of the invention
The purpose of this utility model is the problem existing for the diamond bit of existing slipping formation, provides a kind of pottery
Porcelain base hot pressing impregnated honeycomb ceramics diamond bit, using this drill bit in the geological prospecting of slipping formation is applied, to improve drilling
For the purpose of efficiency and lifting service life.
Another object of the present utility model is exactly to provide a kind of manufacture of the impregnated honeycomb ceramics diamond bit of ceramic base hot pressing
Method.
The purpose of this utility model can be achieved through the following technical solutions：A kind of impregnated honeycomb ceramics Buddha's warrior attendant of ceramic base hot pressing
Aiguille, including steel body, working lining, is characterized in that：It is provided with transition zone, described working lining between described steel body and working lining
With honeycomb ceramics as skeleton, layer be contained within ceramic base powder and diamond particles, steel alloy honeycomb ceramics both sides are provided with mouth of a river protective layer.
Above-mentioned honeycomb ceramics is steel alloy.
Above-mentioned transition zone is simple metal prealloy powder.
Above-mentioned mouth of a river protective layer is the prealloy powder without diamond particles.
The manufacture method of above-mentioned diamond bit is：
A, get out steel body, steel alloy honeycomb ceramics and material requested and instrument；
B, steel alloy honeycomb ceramics is put into and in graphite jig, makees bit matrix skeleton, then load mix homogeneously in honeycomb ceramics
Ceramic base with diamond particles powder as diamond bit working lining, after being filled into the 70-80% of honeycomb ceramics height,
Load simple metal prealloy powder and make transition zone, pressurization compacting, the steel body handled well of halting thereon；
C, present a theatrical performance as the last item on a programme finish after place it in hot pressed sintering on intermediate-frequency hot-pressing sintering furnace, after the completion of sintering, cooling, plane the mouth of a river
Groove, inspection is qualified.
The beneficial effects of the utility model are：Its working lining is mainly ceramic base metal powder, and after the completion of sintering, working lining has
Fragility, be conducive to diamond particles during diamond drilling from sharp and go out sword, drilling efficiency is high, long service life；And work
Make layer with steel alloy honeycomb ceramics as skeleton, be strongly adhered to steel body by transition zone together with, drastically increase working lining
Mechanical performance, compensate for the poor defect of working lining bulk strength that ceramic base metal powder material is likely to occur, actually used
During, diamond particles go out sword well, can effectively carve and take rock, improve drilling efficiency, in order to solve to go out in slipping formation
The problem that existing drilling is skidded.

Frame, layer are contained within ceramic base powder and diamond particles, and steel alloy honeycomb ceramics both sides are provided with mouth of a river protective layer 4.
Above-mentioned honeycomb ceramics is steel alloy, substantially increases the bending strength of ceramic base working lining, contrast is not using honeycomb
Body is the working lining of skeleton, and its bending strength has risen to 800MPa from 100MPa, met the intensity requirement of drill bit.
Above-mentioned transition zone is simple metal prealloy powder, is easy to steel body and working lining is securely joined together.
Above-mentioned mouth of a river protective layer is the prealloy powder without diamond particles, so that the protection mouth of a river.
The manufacture method of above-mentioned diamond bit is：
A, get out steel body, steel alloy honeycomb ceramics and material requested and instrument；
B, steel alloy honeycomb ceramics is put into and in graphite jig, makees bit matrix skeleton, then load mix homogeneously in honeycomb ceramics
Ceramic base with diamond particles powder as diamond bit working lining, after being filled into the 70-80% of honeycomb ceramics height,
Load simple metal prealloy powder and make transition zone, pressurization compacting, the steel body handled well of halting thereon；
C, present a theatrical performance as the last item on a programme finish after place it in hot pressed sintering on intermediate-frequency hot-pressing sintering furnace, after the completion of sintering, cooling, plane the mouth of a river
Groove, inspection is qualified.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
