Abstract
The utility model relates to an alloy filming drill bit, which relates to a drill box body and an alloy bit welded thereon. The exposed surface of the alloy bit is coated with a diamond coating layer which is coated by using a chemical vapor deposition method with hydrogen gas and carbon source gas as raw materials. The diamond filming sheet for a drill bit substitutes a traditional hard alloy cutting knife bit. Therefore, the performance of shock resistance and wear resistance is reinforced obviously. When applied to drilling holes in coal mine production, the utility model can increase the hole drilling efficiency and can reduce the labor intensity and the consumption of drill bits.
Description
Technical field:
The utility model relates to the alloy bit of geological prospecting borehole under the coal mine.
Background technology:
The cutting edge of ordinary rigid alloy as drill bit generally used in Coal Production boring, and when being applied to Coal Production digging, supporting, logical boring in anti-, drilling depth is slow, efficient is low, bit consumption is big, labor strength is high.And the diamond bit cost is too high, is not easy to promote the use of.
Summary of the invention:
The purpose of this utility model provides the drill bit of plated film on a kind of alloy cutter head, makes cutting edge improve hardness and abrasion resistance, has good toughness again, improves drilling efficiency, reduces labor strength, reduces bit consumption.
The purpose of this utility model realizes as follows: this alloy coating drill bit, and relate to and bore storehouse body and welding alloy cutter head thereon, be covered with diamond coatings on the alloy cutter head exposed face.This coating is to utilize chemical gaseous phase depositing process, make raw material with hydrogen, carbon-source gas, be lower than 1000 ℃ and less than an atmospheric condition under, directly coating forms on alloy cutting edge surface, coating layer thickness is at 0.1～0.2mm, existing adamantine hardness of coating and abrasion resistance have good toughness again.
This drill bit can be an alloy cutter head front end form at brill storehouse body, also can be that brill storehouse body front end, middle part all have alloy cutter head, and back level alloy cutter head tactical diameter constitutes the form of reaming bit like this greater than prime alloy cutter head tactical diameter.
This alloy coating drill bit substitutes traditional carbide cutting cutter head with diamond coated, shock resistance and anti-wear performance are obviously strengthened, be applicable to different soft, in, the creeping into of hard formation, the ability of drilling rock layer is brought up to f≤12 by f≤8, can improve drilling efficiency, reduces labor strength, reduce bit consumption, comprehensive result of use significantly improves, and has the characteristic of diamond bit and cost is lower, is convenient to promote the use of.
Description of drawings:
Fig. 1 is the front view of the utility model alloy coating drill bit.
Fig. 2 is the left view of the utility model alloy coating drill bit.
The specific embodiment:
With reference to Fig. 1, Fig. 2, bore the attachment of storehouse body 4 as alloy cutter head 2, adopt the casting of high-quality steel to form.Bore storehouse body 4 front ends the water hole is arranged, rearward end is useful on the screw thread conessi that is connected with drilling rod etc., boring the alloy cutter head 2 that storehouse body 4 front ends are circumferentially evenly arranged by 3 edges of cored solder 3 high-frequency heating welding, alloy cutter head 2 is covered with hydrogen, carbon-source gas on alloy cutter head 2 exposed faces and makes the diamond coatings 1 that the prepared using chemical gaseous phase depositing process is painted as the matrix of diamond coatings 1.
Claims (3)
1, a kind of alloy coating drill bit relates to and bores storehouse body and welding alloy cutter head thereon, it is characterized in that: be covered with diamond coatings (1) on alloy cutter head (2) exposed face.
