Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of pressureless impregnation method and processes high carcass diamond-impregnated bit mould.
Background technology
For meeting national economic development needs, bring into schedule to deep prospecting.Along with the increase of hole depth, the ground consisting of hard rock run into gets more and more, the life-span and drilling efficiency of creeping into the diamond-impregnated bit that hard rock uses are had higher requirement, because drill quality is defective, directly cause putting the paving assistant engineers such as brill and make overlong time, and then affect construction speed and production cost.
For improving the service life of drill bit, current research tendency is the working lining height increasing drill bit.The increase of diamond-impregnated bit working lining height, needs, for the rational flow passage system of drill bit design, to comprise the mouth of a river and tank, cause bit matrix part-structure relative complex, therefore adopts traditional pressure sintering processing to have difficulties.
The high carcass diamond-impregnated bit of current processing structure complexity generally adopts pressureless impregnation method.The utility model patent " a kind of diamond bit " of the such as patent No. 201120065428.6, comprise drill bit rigid body and bit matrix, multiple bit matrix is arranged on drill bit rigid body, the ground floor mouth of a river is provided with between bit matrix, bit matrix is provided with the second layer mouth of a river, adopt pressureless impregnation method to process, add carcass height, improve drilling life of bit.Accompanying drawing 2 is the mould structure schematic diagrames adopting pressureless impregnation method to process high carcass diamond-impregnated bit, and mould comprises bed die and core rod, and core rod is fixedly mounted on bed die, and core rod arranges groove; Form cavity between bed die and core rod, between groove and cavity, be provided with dipping passage; In the groove of core rod, place impregnating metal, load the carcass powder containing diamond particles in cavity, and drilling bit steel body is loaded in mould, then carry out sintering and form bit matrix, make high carcass diamond-impregnated bit.
In this mould structure application process, when bit matrix is too high thus wherein carcass powder is too high, impregnating metal penetrates into bottom carcass powder exists certain difficulty, and dipping effect is bad, causes high carcass diamond-impregnated bit to occur falling block in use or the phenomenon such as very fast of wearing and tearing.
Utility model content
The utility model provides a kind of pressureless impregnation method to process high carcass diamond-impregnated bit mould, dipping non-uniform phenomenon can be reduced when manufacturing drill bit, improve mass-impregnation effect, ensure the mechanical property of bit matrix, and the temperature retention time that can reduce required for drill-bit sintering, enhance productivity.
The technical solution of the utility model is as follows:
A kind of pressureless impregnation method processes high carcass diamond-impregnated bit mould, and comprise bed die and core rod, described core rod is two-layer or sandwich construction.
When core rod is double-layer structure, described core rod comprises core rod one and core rod two, and core rod one is fixedly mounted on bed die, and core rod two is arranged on core rod one; Core rod one and core rod two arrange groove; Form cavity between bed die and core rod, between the groove of core rod one and core rod two and cavity, be provided with dipping passage; The groove of core rod one and core rod two is for placing impregnating metal, and described cavity is for loading the carcass powder containing diamond particles.
When core rod is three-decker, described core rod comprises core rod one, core rod two and core rod three, and core rod one is fixedly mounted on bed die, and core rod two is arranged on core rod one, and core rod three is arranged on core rod two; Core rod one, core rod two and core rod three arrange groove; Form cavity between bed die and core rod, between described groove and described cavity, be provided with dipping passage; Described groove is for placing impregnating metal, and described cavity is for loading the carcass powder containing diamond particles.
The beneficial effects of the utility model are as follows:
1, improve impregnating metal immersion amount bottom carcass powder, improve mass-impregnation effect, ensure the mechanical property of bit matrix;
2, double-deck and multilayer film cored structure is conducive to completing smoothly of dipping process, reduces the temperature retention time required for drill-bit sintering, enhances productivity.
