Abstract
A kind of diamond drill bit belongs to drilling tool.System adopts the cold galvanising technology, diamond is electroplated onto on the cutting edge body of bore bit body head end.Simultaneously, on a fine body head periphery, also be electroplate with diamond layer, thereby it is good to make diamond drill bit of the present invention have an anti-wear performance, long service life, characteristics such as cutting rate and rock penetration performance height are the ideal tools of rock drilling mining.
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.Press the shape of carbide alloy and divide, sheet carbide bore bit and ball (post) profile of tooth hard alloy drill two big series are arranged.The sheet carbide bore bit divides in-line (comprising interrupted in-line), three-blade shape, cross, X-shaped hard alloy drill again.Ball (post) profile of tooth hard alloy drill is pressed cloth number of teeth difference, also can point three teeth, ball (post) the profile of tooth hard alloy drill of the different numbers of teeth such as four teeth, five teeth, six teeth.Above-mentioned all kinds of bore bit all can form the meet standard requirements series of products of (as millimeters such as 38,40,42) of bore bit body head diameter.As once obtaining " novel hard alloy bore bit " (China Geological Univ is opened state's beech etc., 1985) of China national level progress prize in scientific and collective technology.
Above-mentioned hard alloy drill, because the abrasion resistance of carbide alloy is limited, bore bit body head diameter wears away easily, thereby application life, cutting rate, and even rock penetration performance all is subjected to certain limitation.
Purpose of the present invention is to overcome deficiency of the prior art, provides a kind of anti-wear performance good, long service life, the diamond drill bit that rock penetration performance is 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 and diamond layer 6.Cutting edge platform 4 is distributed in bore bit body 1 head end.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; Another embodiment is to adopt to inlay stamen body 7 and be mounted in the manufactured in advance groove of bore bit body 1 head end (hole) and realize.Inlaying stamen body 7 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 7 dew sword surfaces) and bore bit body 1 head garden side face, and its thickness is generally 0.05 millimeter to 0.2 millimeter.Diamond layer 6 electroplate cutting edge platform 4 or inlay stamen body 7 end faces and bore bit body 1 head garden side face on 1003 intermediate metals 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 7 end face intermediate metals 5; Generally thick 0.2 millimeter to 0.8 millimeter of the diamond layer 6 of plating 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 7, the present invention can be divided into ball (post) profile of tooth diamond drill bit and sheet diamond drill bit two big series.
In ball (post) profile of tooth diamond drill bit series, cutting edge platform 4 or inlay stamen body 7 and be ball (post) profile of tooth.Inlay the difference of stamen body 7 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 diamond drill bit kind such as twenties teeth.
In sheet diamond drill bit series, cutting edge platform 4 or inlay stamen body 7 and be sheet.Inlay the difference of stamen body 7 numbers according to sheet cutting edge platform 4 or sheet, a plurality of sheet diamond drill bit kinds such as in-line (comprising interrupted in-line), three-blade shape, cross and X-shaped can be arranged.
The various diamond drill bits of above-mentioned ball (post) profile of tooth and sheet two big series generally can be made the diamond drill bit 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 and water hole 3 are arranged according to the design needs.Diamond drill bit of the present invention and drill steel adopt taper hole or the activity of screwed hole mode to link.
