Description
The invention belongs to drilling tool.
In the prior art, the bore bit that is used for rock drilling and mining is generally hard alloy drill, it is characterized in that in bore bit body head end tungsten carbide button.In recent years, the drilling tool industry development a kind of cemented tungsten carbide integral drill rod, an integral body is made with conventional hard alloy drill and drill steel by system, it is not high to have overcome bit impact energy effective rate of utilization like this, the design of sludge groove, water hole and impact cutting edge is subjected to shortcomings such as certain limitation, improve cutting rate and rock penetration performance, improved condition of labor, saved raw material.Cemented tungsten carbide integral drill rod has ball (post) dentation and sheet two big series, and CN85102269.3 provides a kind of ball profile of tooth serial carbide alloy monoblock drill steel.
Because the abrasion resistance of carbide alloy is limited, bore bit body head diameter wears away easily, thereby the application life of cemented tungsten carbide integral drill rod, cutting rate and rock penetration performance still are subjected to certain limitation.In addition, along with the steel production technology develops rapidly, improve the application life of drill steel greatly, improves the application life of bore bit part in the monoblock drill steel, make it to mate substantially with the application life of drill steel, and be the important channel of development monoblock drill steel.
Purpose of the present invention is to overcome deficiency of the prior art, provides a kind of anti-wear performance good, and the bore bit part is mated with the drill steel part application life substantially, and whole service life is long, the integral diamond drill rod that cutting rate and rock penetration performance are high.
The present invention is made up of bore bit body 1, sludge groove 2, water hole 3, cutting edge platform 4, intermediate metal 5, diamond layer 6, drill steel 7, bit shank 8.Cutting edge platform 4 is distributed in bore bit body 1 head end; Bore bit body 1, drill steel 7, bit shank 8 are by the machine-shaping of standard hex hollow steel Integratively.Cutting edge platform 4 has two kinds of embodiments, and a kind of is that cutting edge platform 4 processes with bore bit body 1 Integratively, and another kind of scheme is to adopt to inlay stamen body 9 and be mounted in the manufactured in advance slotted eye of bore bit body 1 head end and realize.Inlaying stamen body 9 is processed by the high-strength special type steel.Intermediate metal 5 is electroplated on bore bit body 1 head end (comprise cutting edge platform 4 or inlay stamen body 9 dew sword surfaces) and bore bit body 1 head garden side face, and its thickness of coating is generally 0.05 millimeter to 0.2 millimeter.Diamond layer 6 electroplate cutting edge platform 4 or inlay stamen body 9 end faces and bore bit body 1 head garden side face on intermediate metal 5 on, plating is at cutting edge platform 4 or inlay general thick 2 millimeters to 4 millimeters of diamond layer 6 on the stamen body 9 end face intermediate metals 5, electroplates the diamond layer 6 general thick 0.2 millimeter to 0.8 millimeter on bore bit body 1 head garden side face intermediate metal 5.
According to the cutting edge platform 4 or the shape difference of inlaying stamen body 9, the present invention can be divided into ball (post) profile of tooth integral diamond drill rod and sheet integral diamond drill rod two big series.
In ball (post) profile of tooth integral diamond drill rod series, cutting edge platform 4 or inlay stamen body 9 and be ball (post) profile of tooth.Inlay the difference of stamen body 9 numbers according to ball (post) profile of tooth cutting edge platform 4 or ball (post) profile of tooth, three teeth, four teeth, five teeth, six teeth can be arranged, until nine teeth, ten teeth, even a plurality of balls (post) profile of tooth integral diamond drill rod kind such as twenties teeth.
In sheet integral diamond drill rod series, cutting edge platform 4 or inlay stamen body 9 and be sheet.Inlay the difference of stamen body 9 numbers according to sheet cutting edge platform 4 or sheet, a plurality of sheet integral diamond drill rod kinds such as in-line (comprising interrupted in-line), three-blade shape, cross, X-shaped can be arranged.
The various integral diamond drill rods of above-mentioned ball (post) profile of tooth and sheet two big series generally can be made the integral diamond drill rod series of products that bore bit body 1 head diameter meets standard requirements again, as 32,34,36,38,40,42 millimeters of diameters etc.Sludge groove 2, water hole 3 arrange that according to the design needs specification of drill steel 7, bit shank 8 meets standard-required, and the length of drill steel 7 is selected arbitrarily as required.
