The manufacture method of zirconia ceramics split coupling of the present invention and the main distinction of prior art are: prior art is the not front reaming of opening, and the present invention carries out reaming after opening and other external form manufacturing procedures again.
The special beneficial effect that this difference of labor below brings:
There is strain, the flexibility that namely we often say in the product to be processed after opening (or claiming C type earthenware) within the specific limits (0.05mm left and right); The processed goods of opening (or claiming O type earthenware) is not a pure rigid body; Therefore before opening, reaming is processed rigidity body exactly, after opening, reaming is that flexible pipe body is processed, this is that the present invention is different from the most crucial place of prior art, also just because of this difference, makes the present invention possess the incomparable advantage of prior art.
For the endoporus of earthenware being expanded, the external diameter that grinds rod iron (being attached with the high accuracy rod iron of diamond lap material) is larger than the internal diameter of earthenware to be processed.In order to make to grind rod iron in process, enter into smoothly inner holes of ceramic tubes, the front end that grinds rod iron need to be produced the Lead-In Area of tapering, the precision in order to guarantee that endoporus grinds simultaneously, grinding rod iron need to have the very high and size of long one section of external diameter precision to be slightly larger than the region (abrasive areas guaranteeing hereinafter referred to as inner hole precision) of article internal diameter to be processed.
Fig. 1 is the amount of grinding of unit advance distance of prior art and the schematic diagram of the relation of advance distance, when adopting the technique of prior art to carry out reaming, because O type earthenware has high rigidity, so the earthenware major part amount of being polished occurs in earthenware and from grinding rod iron Lead-In Area, enters one section of narrow region of the abrasive areas that inner hole precision guarantees.In this section of region, the amount of grinding larger (being that grinding rate is larger) of unit advance distance, needed propulsive force also larger (seeing the peak value place of Fig. 1) now, but enter into after the abrasive areas of grinding the assurance of rod iron inner hole precision, the amount of grinding of its unit advance distance (grinding rate) obviously reduces (in Fig. 1, showing as curve sharply reduces), but in order to guarantee the grinding precision of endoporus, earthenware must grind works (advance with return and move) 1-3 time of reversing on rod iron.Therefore prior art is in whole process of lapping, there is obvious lack of uniformity in grinding rate, most amount of grinding is to complete in the very zonule advancing for the first time, all the other most propellings and return operation only complete the very little a part of amount of grinding of residue in order to improve earthenware aperture precision, thereby from working (machining) efficiency, have significantly waste (Fig. 1, shaded area represents amount of grinding); In addition because most of amount of grinding completes in very short main abrasive areas, needed propulsive force is very large, and the variation of amount to be ground (closely related with draw point external diameter and earthenware to be processed aperture) will obviously have influence on the size of propulsive force, needed propulsive force is excessive or change and obviously will bring a series of adverse consequences.
Fig. 2 is the schematic diagram of the amount of grinding of unit of the present invention advance distance and the relation of advance distance, while using manufacture method of the present invention to carry out reaming, can there is within the specific limits elastic deformation in C type earthenware, when thereby C type earthenware advances on grinding rod iron, can there is trace with the variation (abrasive areas guaranteeing) of grinding rod iron external diameter and change in its endoporus aperture from Lead-In Area to inner hole precision, therefore in this region, the amount of grinding of unit advance distance and needed propulsive force do not have O type earthenware so large (there is no to produce very steep peak in Fig. 2), also therefore can effectively alleviate the problem of propulsive force significant change, when C type earthenware enters into after the abrasive areas of the inner hole precision assurance of grinding rod iron, still there is certain deformation quantity in C type earthenware, thereby and the power that has certain effect between grinding rod iron, therefore in this region, C type earthenware still can effectively grind (situation about sharply declining does not occur the amount of grinding of unit distance in Fig. 2), therefore the main milling zone of the present invention comprises the abrasive areas that part Lead-In Area and whole inner hole precisions guarantee, compared with prior art, there is obvious expansion in this region.The present invention not only can effectively grind in propelling in addition, also can effectively grind, thereby the amount of grinding in whole process of lapping is obviously greater than the amount of grinding (shaded area of schematic diagram is larger) of Fig. 1 in the time of return.
Comprehensive, the grinding rate of prior art in its main milling zone is larger, but its main milling zone is too narrow, therefore average not high to its working (machining) efficiency of whole process of lapping, in main abrasive areas, needed propulsive force is compared with changing obviously greatly and with product is different simultaneously, and this can cause adverse effect to production.Although the present invention's peakedness ratio prior art on grinding rate is on the low side, but its main milling zone is obviously greater than the main milling zone of prior art, from whole process of lapping grinding efficiency of the present invention, be obviously better than prior art, its propulsive force integral body is less and comparatively steady in addition, and be subject to the endoporus aperture of processed product and the impact of grinding rod iron change in size less, thereby the difficulty of processing reduces greatly, for full-automatic reaming provides good basis.
The present invention compared with prior art, has the following advantages:
1, time processing quantity increases considerably:
Due to propulsive force, prior art once can only be processed 2 finished products; And propulsive force of the present invention is relatively little and steady, once can process 10-18 finished product (product length different and slightly change).
2, time processing surplus increases considerably:
The propulsive force of prior art is subject to the impact of allowance very obvious, allowance just may cause slightly greatly the even serious problems of " steel-fastening rod " of operating difficulties, and C type earthenware of the present invention has adaptive ability, its propulsive force of allowance generation obvious deviation can not occur sharply to change yet.In actual production, the time processing surplus of prior art is about 0.002mm, and the present invention can reach 0.004mm.Therefore, working (machining) efficiency of the present invention is prior art 4 times.
3,, to coming the requirement of blanking aperture significantly to reduce, reduce that processing gets stuck simultaneously and wait extremely:
Prior art requires very high to the aperture of supplied materials, allowance just may cause slightly greatly the even serious problems of " steel-fastening rod " of operating difficulties, and C type earthenware of the present invention has adaptive ability, its propulsive force of allowance generation obvious deviation can not occur sharply to change yet.Can significantly alleviate because of Aperture deviation and process the problem that gets stuck that gimmick deviation is brought.
4, can according to test case, to reaming aperture, adjust in time, minimizing is scrapped:
Because the contact engaging and separating force of split coupling is relevant with the microcosmic of material property, endoporus aperture and endoporus sign, therefore need the regular performance according to test contact engaging and separating force suitably to adjust reaming aperture, prior art due to reaming operation and inspection process relatively far apart, therefore after going wrong, easily cause in enormous quantities and scrap, and the present invention can react in time to reaming operation, improve response speed, minimizing is scrapped, in actual production, endoporus processed finished products rate of the present invention promotes 10% than prior art.
5, can realize automation reaming:
Prior art has high requirements (people's sensation is very crucial) to reaming gimmick, otherwise is easy to get stuck, and is therefore difficult to realize automation; The present invention requirement in this regard significantly reduces, and for the exploitation of automation equipment provides good condition, this operation has realized automation at present.
Should be understood that; the above-mentioned description for preferred embodiment is comparatively detailed; can not therefore think the restriction to scope of patent protection of the present invention; those of ordinary skill in the art is under enlightenment of the present invention; do not departing from the scope situation that the claims in the present invention protect; can also make the various deformation such as replacement, simple combination, within these all fall into protection scope of the present invention, the scope of asking for protection of the present invention should be as the criterion with claims.
