Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Embodiment.
See Fig. 1 to Fig. 6, the diamond core drill bit in the present embodiment comprises diamond segment 1 and steel alloy cutter hub 2, and diamond segment 1 and steel alloy cutter hub 2 are cylinder-like structure, and the afterbody of diamond segment 1 is fixed on steel alloy cutter hub 2.The external diameter of diamond segment 1 is greater than the external diameter of steel alloy cutter hub 2 usually, and the wall thickness of diamond segment 1 is greater than the wall thickness of steel alloy cutter hub 2 usually, and the axis of diamond segment 1 axis that is usual and steel alloy cutter hub 2 is overlapping.
Diamond segment 1 in the present embodiment is made up of circumscribed layer 3 and inscribe layer 4, namely diamond segment 1 by and be only made up of circumscribed layer 3 and inscribe layer 4, circumscribed layer 3 and inscribe layer 4 are cylinder-like structure, the diameter of circumscribed layer 3 is greater than the diameter of inscribe layer 4, inscribe layer 4 is sleeved in circumscribed layer 3, and the outside wall surface of inscribe layer 4 and the internal face of circumscribed layer 3 are sintered to fix.The wall thickness of circumscribed layer 3 is usually equal with the wall thickness of inscribe layer 4.
The head of the circumscribed layer 3 in the present embodiment is provided with the circumscribed layer mouth of a river, the head of inscribe layer 4 is provided with the inscribe layer mouth of a river, the shape at the circumscribed layer mouth of a river is identical with the shape at the inscribe layer mouth of a river, the size at the circumscribed layer mouth of a river is identical with the size at the inscribe layer mouth of a river, the head of circumscribed layer 3 and the head of inscribe layer 4 flush, a circumscribed layer mouth of a river and the inscribe layer mouth of a river alignment corresponded.
Under normal circumstances, the material of circumscribed layer 3 is coarse diamond.The diamond particles of the material of circumscribed layer 3 to be granularity be 30-50 micron, the diamond particles of the material of inscribe layer 4 to be granularity be 35-60 micron.
The circumscribed layer mouth of a river in the present embodiment and the quantity at the inscribe layer mouth of a river are two, and two circumscribed layer mouths of a river are evenly distributed in the head of circumscribed layer 3 circumferentially; A circumscribed layer mouth of a river and the inscribe layer mouth of a river alignment corresponded, i.e. a circumscribed layer mouth of a river and an inscribe layer mouth of a river alignment, another circumscribed layer mouth of a river and the alignment of another inscribe layer mouth of a river.The degree of depth at the circumscribed layer mouth of a river is greater than the half of circumscribed layer 3 length.
Thin diamond wall in the present embodiment is drilled in actual manufacture process and can improves according to actual needs, the diamond concentration of circumscribed layer 3 and inscribe layer 4 can be different, the diamond particles degree of circumscribed layer 3 and inscribe layer 4 can be different, and the matrix formula of circumscribed layer 3 and inscribe layer 4 can adopt the alloy powder of varying strength.Circumscribed layer 3 can diamond concentration be preferably 75%-95%, and inscribe layer 4 can diamond concentration be preferably 65%-85%.Traditional type diamond segment is overall unified concentration on diamond concentration, and carcass is overall unified strength, in use because circumscribed layer 3 and inscribe layer 4 exist diameter difference, so there is linear differential and produce wearing and tearing difference; And the wearing and tearing of circumscribed layer 3, in the processing size being directly reflected in hole and precision, rapid wear can cause client to occur processing accident.Circumscribed layer 3 and inscribe layer 4 hierachical structure, variable concentrations, variable grain degree diamond and varying strength carcass can be adopted, to reduce the wearing and tearing difference of each interlayer of diamond segment 1 further, shorten cutting face width, improve drilling speed, improve working (machining) efficiency, control the wearing and tearing of head outer diameter, improve machining accuracy, stronger in the adaptability of rapidoprint.
In addition, it should be noted that, the specific embodiment described in this description, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this description is only to the explanation of the utility model structure example.The equivalence change that structure, feature and principle described in all foundation the utility model inventional idea are done or simple change, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
