Description
Technical field
The present invention relates to Geological Engineering technical field, in particular to a kind of diamond bits and its system for engineering investigation
Preparation Method.
Background technology
Currently, the diamond bit market share of the China for engineering investigation accounts for entire field of drill about 30%.Engineering is surveyed
The characteristics of examining is that drilling is shallow, is usually no more than 150m, but the stratum of the depth and variation of lithological are big.It is frequently moved to adapt to drilling machine
It is dynamic, small portable drilling machine is mostly used, the pressure capacity of portable drilling rig is small and rotary torque is small.And existing normal diamond drill bit table
Reveal drilling timeliness it is low, drilling effect is undesirable, and the service life of drill bit is not also grown.
Existing manufacture diamond bit is frequently with hot-press method or electro-plating method.Due to the drill bit knot of both methods manufacture
Structure is relatively simple and single, and it is bad that effect is but shown for drilling complexation and for engineering investigation.Electro-plating method system
Although the drill bit adaptability made is wider, rate of penetration is higher, is reduced using the longevity since the gauge effect of drill bit is undesirable
Life.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of adaptation scientific and reasonable for structure, to stratum
The diamond bit for engineering investigation that property is wide, drilling effect is excellent, while the present invention also provides the diamond bits
Preparation method, this method are simple for process, of low cost.
To achieve the above object, the diamond bit for engineering investigation of the invention, including drilling bit steel body and setting exist
The drill bit sector cutting tooth of the drilling bit steel body front end is provided with the mouth of a river between adjacent two fan-shaped cutting tooths, and special character exists
In:The sector cutting tooth is composed of fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth, the sector scalariform cutting tooth
Front end cutting face be slope, it is described sector cutting tooth on offer drill bit annular groove.
Any one of following scheme can be used as the preferred embodiment of diamond bit of the present invention:
The ratio between the column cutting tooth and the projected area of bottom of the tooth labial surface of the scalariform cutting tooth are 0.30~0.45 ︰ 1.
The front end cutting face (5.1) forms the fan-shaped cutting angle of back of tooth (6), the sector cutting tooth with bit cutting plane
The value of relief angle (6) is in 15 °~30 ° ranges.
The quantity of the drill bit annular groove is 1~3.
In the sector column cutting tooth, a concentration of the 80~100% of diamond, granularity is 30/40 purpose in diamond
The 15~35% of diamond weight are accounted for, granularity is that 40/50 purpose accounts for the 65~85% of diamond weight.The concentration of diamond herein
System uses " diamond composition world concentration standard ", i.e., 100% concentration contains 4.39 carats of diamond in indicating per cubic centimeter.
In the sector scalariform cutting tooth, a concentration of the 65~75% of diamond, granularity is that 30/40 purpose accounts in diamond
The 30~50% of diamond weight, granularity are that 40/50 purpose accounts for the 50~70% of diamond weight.
The tyre body hardness of the sector column cutting tooth is HRC12~HRC25, and wearability is between 210~250mg;Institute
The tyre body hardness for stating fan-shaped scalariform cutting tooth is HRC10~HRC18, and wearability is between 270~320mg.Fan-shaped column cutting
The tyre body hardness of tooth and wearability are higher, and the hardness and wear resistance of fan-shaped scalariform cutting tooth is relatively low;And it works in drill bit sector
Annular groove is opened up in the middle part of tooth, such drill bit plays the role of the dual broken rock of compact bit and normal diamond drill bit, from basic
On change the deficiency of normal diamond drill bit, be conducive to the effect for improving fractured rock.
The invention also discloses the preparation methods of the diamond bit for engineering investigation, include the following steps:
1) according to designed formula, respectively by diamond, the carcass of fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth
Powder is uniformly mixed in the ball mill with binder, is respectively charged into the steel of prefabricated fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth
In mould, it is sent into cold-press moulding in forcing press, is prefabricated into fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth;
2) fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth arranged in sequence are assembled in graphite jig, is subsequently filled into guarantor
Diameter layer powder and gauge polycrystalline material, in pressure after drilling bit steel body, hot-pressing processing in feeding intermediate frequency furnace;
3) release is come out of the stove immediately after hot-pressing processing, slowly cools to 30 DEG C hereinafter, mould unloading is surveyed to get to for engineering
The diamond bit examined.
Preferably, in step 1), when the cold pressing, the pressure for being cold-pressed fan-shaped column cutting tooth is 20~24MPa, pressurize
7~10s of time;The pressure of the fan-shaped scalariform cutting tooth of cold pressing is 18~22MPa, 6~7s of dwell time.
It is further preferred that in step 2), when the hot pressing, temperature is 945~955 DEG C, and pressure is 13~16MPa,
2.5~3.5min of soaking time, soaking time pressurize always.
The present invention the diamond bit for engineering investigation, from engineering investigation feature and formation characteristics, pass through by
Drill bit sector cutting tooth is designed as being composed of fan-shaped column cutting tooth and fan-shaped scalariform cutting tooth, and the fan-shaped scalariform
The front end cutting face of cutting tooth is designed as slope;Wherein fan-shaped column cutting tooth is the main body of fractured rock, and fan-shaped scalariform is cut
It cuts tooth and plays the fan-shaped column cutting tooth of support, while playing addi-tional crusher rock;The drill bit of this structure, drill bit fan
Shape cutting tooth and the contact area of bottom hole rock are smaller, the contact area of drill bit and rock can be effectively reduced, in identical bit pressure
Under the conditions of, can significantly improve drill bit than pressure value, be conducive to cut rock, be adapted to prospecting type portable drilling rig drilling;Simultaneously
Again can effectively cooling diamond drill bit and timely cleaning hole bed rock powder, improve the efficiency of fractured rock.It is cut in the drill bit sector
Cut after tooth cutting face opens up drill bit annular groove, which changes the mode of drill bit fractured rock, can device to hole bed rock stone with point
Ring mode is crushed, and increases the scope of freedom of bottom hole rock, improves conformability of the drill bit to rock;Bit operation tooth is
Inhomogeneous structure, diamond concentration height, the tyre body hardness of fan-shaped column cutting tooth are high, and wearability is strong, small with rock contact area,
Thus entire drill bit sector cutting tooth plays the dual broken rock effect of compact bit and normal diamond drill bit;Fundamentally change
Become insufficient existing for normal diamond drill bit.
Meanwhile the preparation method of patent of the present invention devises the manufacturing process for being different from conventional method, pressure sintering with it is cold
Platen press combines, and plays the double dominant of hot-press method and cold compaction process, it is ensured that bit performance is stablized, and improves drill bit to stratum
Adaptability.
