Description
Technical field
The present invention relates to a kind of improvement of wearing piece preparation method, particularly a kind of diamond and the compound system of metal base
Make the method system and its product of wearing piece, can be applied to make the drill bit of various Drillings, or other wearing piece performance improvements.
Background technology:
Now with the more and more higher of mechanization degree, many work are all to take machining mode to substitute traditional hand
Work cooked mode, as drill, plough and mountain on forestry harvesting operation etc. now all using do mechanization operation, or even family
Cleaning work also all starts to use do mechanization operation, and thus the requirement for wearing piece is also more and more, more and more higher;It is at present
The performance for improving wearing piece is made all in the key position of wearing piece using hard metal article in many cases, such as drill bit
Cutting parts, the tip of colter etc., but found in actual job, it is just inadequate using hard alloy or rub proofness,
In this way again it has been proposed that cover polycrystalline diamond on hard alloy, i.e., hard alloy key position in a manner of glomerocryst
Surface covers an at least diamond, further to improve the anti-wear performance of wearing piece;It can be that while compound on hard alloy
Diamond, can obtain comparison high hardness, but when encountering the larger rock or soil layer of hardness, be compounded with the hard of diamond
Matter alloy wear-resisting part wears still quickly, and it is low to show as short life, efficiency, and such sintered carbide ball teeth drill bit has just had a strong impact on broken
Crushed rocks or the effect for digging soil layer.It is exactly to take the hard hard that is pressed into of interference fit to close polycrystalline diamond to also have in addition a kind of
It is golden so easily bulk material to be split in vivo, or very big internal stress is produced, split, why can go out in use
Existing such case, because the hardness of polycrystalline diamond is higher than hard alloy, main body is closed diamond is pressed into described hard
In hole, it is possible to by the cemented carbide body squeeze crack, even if without squeeze crack, the hard alloy spherical-teeth main body is also formed with
Larger internal stress, and shock resistance is influenceed, in addition, diamond solderability is poor, realized essentially by connection is difficult to solder to.Cause
This is necessary to be improved this.
By patent retrieval and do not find there be the patent literature constructed with the present invention, related to the present invention is main
Have following:
1st, Patent No. CN201410290940.9, the invention of entitled " shock resistance diamond hard alloy complex sheet "
Patent, it which disclose a kind of diamond hard alloy complex sheet of new structure.Closed including polycrystalline diamond layer and hard
Auri body, is assembled together using diamond dust and hard alloy substrate, and diamond dust sinters under high pressure and high temperature condition
Form polycrystalline diamond layer and form diamond hard alloy complex sheet with hard alloy substrate;Wherein, the carbide matrix
There is cylindrical boss on the assembly interface of body, boss top end face there are the hemispherical projections filled in dot matrix;The upper edge of the cylindrical boss
It is waveform hierarchic structure with lower edge;Lower edge is than on along big.
2nd, Patent No. CN201410057543.7, it is entitled " to improve the diamond-coated hard alloy of point of a knife intensity
The patent of invention of cutting element ", the diamond-coated hard alloy cutting element for improving point of a knife intensity is which disclose, is carried
Peel resistance between high diamond film and tool base, point of a knife intensity is improved, and improve and resistance to collapse knife and wear resistance.Should
Diamond-coated hard alloy cutting element, have from the tool base of tungsten carbide base carbide alloy and the boundary of diamond film
The part that the metal bound phase of 8 μm of depth is most deep to inside towards tool base is gone by being chemically treated the part being removed
Except metal bound phase region, by near point of a knife(From the maximum region for being no more than 100 μm in point of a knife front end)Rear knife face it is straight
Angular cross section is observed, between the tungsten carbide in metal bound phase region is removed except part and between tungsten carbide and other carbide
With reference to the tungsten carbide crystal boundary beyond crystal boundary, the metal bound phase of 10~300nm thickness is with more than the 50% of tungsten carbide crystal boundary length
Ratio is present, and the chromium for the metal bound phase being present in tungsten carbide crystal boundary is more than 0.21 0.40 relative to the mass ratio of cobalt
Below.
3rd, patent publication No. CN1021288008, entitled " the compound detritus button down-the-hole of polycrystal diamond hard alloy
The patent of invention of drill bit and its manufacturing process ", it which disclose a kind of compound detritus button of polycrystal diamond hard alloy and dive
Drill and its manufacturing process, including hard alloy spherical-teeth main body (1), in described hard alloy spherical-teeth main body (1) at least
Provided with a polycrystalline diamond.Described polycrystalline diamond is polycrystalline diamond short cylindrical (2), is located at described hard alloy
In hole ravine in button main body (1), the length and diameter dimension of described polycrystalline diamond short cylindrical (2) are 1 ~ 50mmX φ
1~φ30mm.The down-the-hold drill bit steel body of required size is obtained by machining mode, then by polycrystal diamond hard alloy
The hard alloy spherical-teeth main body of hard alloy composite ball tooth is fixed in the hole of down-the-hold drill bit steel body, and solid composite teeth is carried out to down-the-hold drill bit steel body
Post-process quality inspection packaging outbound.
Although these above-mentioned patents have been related to application of the diamond in hard alloy, but carefully analyzing to see
Go out, for these patents all without foregoing application mode is changed, wherein patent publication No. is CN1021288008, entitled
The patent of invention of " polycrystal diamond hard alloy composite rock breaking button down-the-hole bit and its manufacturing process " is exactly a kind of typical
Polycrystalline diamond short cylindrical is inlayed by way of being interference fitted or welding and is fixed on described hard alloy spherical-teeth main body
Way in hole, however, such connected mode has following defect:Because the hardness of polycrystalline diamond is higher than hard alloy,
Diamond is being pressed into the hole of described hard alloy spherical-teeth main body, it is possible to squeeze the hard alloy spherical-teeth main body
Split, even if without squeeze crack, the hard alloy spherical-teeth main body is also formed with larger internal stress, and unfavorable shadow is produced to overall performance
Ring, so solved for foregoing diamond in hard alloy using some existing problems still without effective, because
This is necessary to need further to be studied.
The content of the invention
