Description
Technical field
This utility model is related to diamond bit application and in particular to a kind of diamond drill bit matrix is to diamond handle
The test device of holding force and method, for realizing the quantitative assessment to diamond hold for the bit matrix.
Background technology
For solving the problems, such as that superficial part resource peters out to alleviate resource supply and demand contradiction and the need for all kinds of scientific researches
Will, deep drilling work in recent years is widely carried out with hot dry rock probing work.Due in deep drilling, the temperature in shaft bottom
Can increase with boring deep increase；In hot dry rock probing, the temperature of bit matrix can be higher.Therefore, drill bit needs in difference
Carry out operation under temperature conditionss, and temperature is obvious to the performance impact of drill bit, hold can reduce with the rising of temperature.At this
In a little probing work, because the life-span of diamond bit and efficiency deficiency create great shadow to the efficiency of probing and cost
Ring.And what the life-span of diamond bit and efficiency deficiency caused to the hold deficiency of diamond often caused by bit matrix.
In the case that the life-span of diamond bit and efficiency are diamond bit is rational in infrastructure, carcass property and stratum be adapted, depend on
In the hold (also known as plating power) to diamond for the carcass.Hold increases, and diamond exposure can accordingly increase, and drill bit is every
The penetraction depth turning around increases, and then so that drilling efficiency is increased；Meanwhile, the increase of diamond exposure also can improve bottom lip
Face working condition, reduce flushing liquor and rock dust to erosion of carcass etc., improve drilling life of bit；In addition, carcass is to diamond
Hold increase, the ratio of diamond drop-off reduces, and effective rate of utilization increases, thus improving the life-span of diamond bit.
Measurement to diamond hold both at home and abroad at present and sign do not have unified method, do not have the test dress of correlation yet
Put, adopt the method for qualitative analysis such as scanning electron microscope (SEM) morphology analysis, energy spectrum analysiss and bending strength rate of descent (hold more
Coefficient), the semi-quantitative analysis method such as tensile strength rate of descent combine Indirect evaluation hold, these methods are in practical application
In very inconvenient, and the size of sign hold that can not be quantitative well.Accordingly, it is desirable to provide a kind of bit matrix is to gold
The test device of hard rock hold and method, can be used to the size of quantitative evaluation hold, so that the setting of matrix formula
The optimization more science of meter and preparation technology and simplicity, this has important meaning for the life-span and efficiency improving diamond bit
Justice.
Content of the invention
The technical problems to be solved in the utility model is, for deficiencies of the prior art, provides a kind of Buddha's warrior attendant
