Description
Technical field
The utility model belongs to hammer drill corollary equipment field, is specifically related to a kind of Composite Button bore bit.
Background technology
Rock drilling is the work utilizing hammer drill Drilling borehole or big gun hole in the rock of ore deposit, and the mechanical rock drilling method of main employing, is divided into impact type, rotary and rotary impact type according to the manner of execution of drilling tool.When rock drilling is holed, rock drilling is carried out in the working end bore bit of applicable strata structure being installed on hammer drill, high performance special rolling-mill section selected by bore bit and pricker trousers, through Precision Machining and bulk heat treatmet, post tooth selects the carbide alloy of high-quality, process through the inlaid solid tooth of heat, Columnar tooth drill rod head has good hardness and toughness, wear resistant corrosion resistant.
In actual production, ore body rock stability, the perfect condition of uniform in material is actually rare, and rock stratum is mostly intricate, and strike tilts, Columnar tooth drill rod head works in this case, often there is folder pricker phenomenon, cause whole group of Drilling instrument cannot take out in big gun hole, cause drilling tool to damage, big gun hole is scrapped, and brings unnecessary waste to enterprise.Current Columnar tooth drill rod head, in its use procedure, due to the structure of ore body rock stratum and the structure problem of bore bit itself, when Drilling, be easy to cause the inner machined surface out-of-flatness in big gun hole, bore bit is easy to folder pricker phenomenon occurs, cause bore bit not exit, cause scrapping of bore bit and big gun hole.
Utility model content
The purpose of this utility model is to provide a kind of Composite Button bore bit, to solve existing Columnar tooth drill rod head, card pricker phenomenon easily occurs, causes bore bit not exit, cause the problem that bore bit and big gun hole are scrapped.
For achieving the above object, the technical solution of the utility model is: a kind of Composite Button bore bit, comprise bore bit 1, pricker trousers 2, post tooth 3, ash pit 4, cutting table 5 and drain hole 6, bore bit 1 is located at the top of pricker trousers 2, the ring surface of bore bit 1 is provided with at least six cutting tables 5 uniformly, ash pit 4 is provided with between cutting table 5, drain hole 6 is located on ash pit 4, the top of cutting table 5 is provided with top diamond cutting layer 7, the bottom of cutting table 5 is provided with bottom diamond cutting layer 8, bore bit 1 top center is provided with apical tooth 9, and post tooth 3 is located at the top of cutting table 5.
Preferably, the quantity of cutting table 5 is six.
Preferably, top diamond cutting layer 7 is provided with upper cutting edge 10.
Preferably, 120 degree, top diamond cutting layer 7 interval arranges one.
Preferably, bottom diamond cutting layer 8 is provided with bottom cutting edge 11.
Preferably, 120 degree, bottom diamond cutting layer 8 interval arranges one.
The utility model has the advantage of: the position of reasonable Arrangement post tooth, in bore bit top center, apical tooth is set, each cutting table arranges a post tooth, make the distribution of post tooth more reasonable, the stress surface of bore bit is made to be evenly distributed on each post tooth, at 120 degree, the interval, top of cutting table, a top diamond cutting layer is set, at 120 degree, the interval, bottom of cutting table, a bottom diamond cutting layer is set, top diamond cutting layer and bottom diamond cutting layer are all provided with corresponding cutting edge, adamantine extreme hardness, not only effectively can protect cutting table, and can move back in pricker work irregular big gun hole machined face is cut, make to move back pricker work to be more prone to, improve the operating efficiency of bore bit, avoid the generation of folder pricker phenomenon, decrease scrapping of bore bit and big gun hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Reference numeral implication is as follows: bore bit (1), pricker trousers (2), post tooth (3), ash pit (4), cutting table (5), drain hole (6), top diamond cutting layer (7), bottom diamond cutting layer (8), apical tooth (9), upper cutting edge (10), bottom cutting edge (11).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of Composite Button bore bit as depicted in figs. 1 and 2, comprise bore bit 1, pricker trousers 2, post tooth 3, ash pit 4, cutting table 5 and drain hole 6, bore bit 1 is located at the top of pricker trousers 2, the ring surface of bore bit 1 is provided with at least six cutting tables 5 uniformly, ash pit 4 is provided with between cutting table 5, drain hole 6 is located on ash pit 4, the top of cutting table 5 is provided with top diamond cutting layer 7, the bottom of cutting table 5 is provided with bottom diamond cutting layer 8, bore bit 1 top center is provided with apical tooth 9, post tooth 3 is located at the top of cutting table 5, top diamond cutting layer 7 and bottom diamond cutting layer 8 all by gas welding founding on cutting table 5 surface.
Big gun hole can be taken out more smoothly after drilling work completes to make bore bit, avoid the generation of pressing from both sides pricker phenomenon, the quantity arranging cutting table 5 is six, and upper cutting edge 10 is set on top diamond cutting layer 7, bottom diamond cutting layer 8 arranges bottom cutting edge 11, and ensure that 120 degree, top diamond cutting layer 7 interval arranges one, 120 degree, bottom diamond cutting layer 8 interval arranges one, top diamond cutting layer 7 bottom diamond cutting layer 8 is evenly arranged on cutting table, is conducive to bore bit and exits in process the chopping of rock stopped.
