Ukucija Ekwenziweni Kwemishini Eqondile

1. Kungani Kudingeka Umshini Wokujuba

Amashafu aqondileyizinto ezibalulekile ezisetshenziswa emishinini, ezinhlelweni zezimoto, kuma-hydraulics, amarobhothi, kanye nemihlangano ye-aerospace.
Ngokuvamile zisebenza njengeizingxenye zokukhwelanangezihlahla, ama-bearings, noma izimpawu, laphoukuphela kwendawo, ukuzungeza, nokuqondilekuthinte ngqo ukusebenza kwesistimu.

Ngisho nangemva kwalokhoukuphenduka, ukugaya, noma ukuphenduka kanzima, indawo ye-shaft isengaba:

Iziqongo ezincane nezigodi(ubukhulu obuphezulu buphezulu kakhulu ukuthi ungavalwa noma uthintene).

Amaphutha efomunjenge-taper, umgqomo, noma i-ovality.

Izingcindezi ezisalelayokusukela ekugayeni noma ekwelapheni ukushisa.

Izici zokugcoba ezingahambisaniebusweni.

Lokhu kungapheleli kungaholela kulokhu:

Ukuguga ngokweqile kwama-bearings noma ama-seal,

Ukuvuza kumasistimu we-hydraulic,

Umsindo noma ukudlidliza ngesikhathi sokuzungezisa, kanye

Ukunciphisa impilo yokukhathala kwe-shaft.

Ngakho-ke, i-honing isetshenziselwa:

Zuzaukunemba kweleveli ye-micron-ububanzi, ubuyindilinga, kanye nobuqotho.

Khiqiza aisiphetho sendawo elawulwayongephethini ethile yokumahhadla nokuthungwa.

Susa ukuhlanekezela kwendawo kanye nokusha kokugaya.

Thuthukisa i-layisha{0}indawo yokuthwalafuthiukugcinwa kwe-lubrication.

Khulisa i-amandla okukhathala nokumelana nokugqokawe shaft.

2. Imisebenzi Yomshini Wokucija Ekukhiqizeni I-Shaft

3. Inqubo Yokujula Yenziwa Kanjani (Isinyathelo-nge-Isinyathelo)

Isinyathelo 1: Ngaphambi-Ukumaka

Amashaft akhonawaphenduka, umhlabathi ongenamaphakathi, nomaumhlabathi we-cylindricalkusayizi kancaneusayizi omkhulu(ngokuvamile ngo-0.02–0.1 mm).

Inhloso ukushiya isitokwe esincane sokucija.

Ingxenye ingabaukushisa-kulatshiwe(ngobulukhuni) ngaphambi kokuqeda.

Isinyathelo sesi-2: Ukusetha nokulungisa

I-shaft ifakwephakathi kwezikhungo noma ku-chuck enembileukugcina ukuhleleka okuphelele ku-eksisi.

I honing mandrel noma umkhono kuyintokuhambisana ne-coaxiallykushaft.

Ukulungiswa kungavumela i-shaft ukuthizungezisa, shintshashintsha, noma uhlale umile, kuye ngomklamo womshini.

Isinyathelo sesi-3: Ithuluzi kanye Nokukhethwa Kwe-Abrasive

Ngobaukucija kwangaphandle, imikhono e-abrasive noma izicathulo zifakwe ekhanda le-honing elinwebeka ngokuzungezile ku-shaft.

Ngobaukucijwa kwangaphakathi(uma i-shaft ine-bore), i-mandrel yangaphakathi enamatshe abrasive isetshenziswa.

Izinto ezivamile zokugwaza:

I-aluminium oxide noma i-Silicon Carbidengezinsimbi.

I-CBN noma iDayimaneokwe-alloy eqinile noma -amashafu apuliniwe e-chrome.

I-Honing oil noma i-emulsioninikeza ukuthambisa, ukupholisa, nokususwa kwe-chip.

Isinyathelo sesi-4: Ukucija Ukusebenza

Umshini wokucija uyasebenzaukunyakaza okulawulwa kanyekanye:

Ukuzungezisa:Ishaft noma ithuluzi lizungeza ku-100–500 rpm.

Ukubuyisela:Ithuluzi noma ingxenye ihamba nge-axially ngobude be-shaft (imvamisa ijubane le-stroke elingu-10–30 m/min).

I-Radial Pressure:Izicathulo ezi-abrasive zisebenzisa ingcindezi elawulwayo ukuze zisuse izingqimba ze-microscopic zezinto ngokulinganayo.

Ngokuhlangene, lezi zinyathelo:

Dala i-iphethini ye-crosshatchebusweni (i-engeli ngokuvamile i-30℃-45 degree).

Susa iziqongo eziphakeme futhi ucwenge ukuthungwa kube aukuphela kwethafa.

Lungisa amaphutha efomu aqoqwe kusukela ekugayeni noma ekuhlanganiseni ukuhlanekezela.

Isinyathelo sesi-5: -Enqubweni Yokuqapha

Imishini yokucija ngokunemba ivame ukusetshenziswakokuthi{0}}cubungula ama-gauge noma amasistimu okulinganisa komoyaukulandelela ububanzi nobuyindilinga ngesikhathi sangempela.

Ukulawula kwe-CNC kulungisa ingcindezi, isivinini, nobude be-stroke ukuze kuzuzwe i-geometry eqondiwe nokuqeda.

Isinyathelo sesi-6: Final Finishing Pass

Amatshe-acwebile (600–1200 grit) asetshenziselwa ukudlula okumbalwa kokugcina.

Umgomo uwukuphela kwendawo ngokuvamile phakathi:

I-Ra 0.05–0.2 µmama-hydraulic noma ama-bearing shafts,

Rz Ngaphansi noma kulingana no-1 µmokwezindawo zokuvala.

Lokhu kuqinisekisa ukuziphatha okuhle kokugcoba kanye nokugqokwa okuncane ngesikhathi sokusebenza.

Isinyathelo sesi-7: Ukuhlanza kanye Nokuhlolwa Kwekhwalithi

Ngemva kokucija, i-shaft ingena:

Ukuhlanza kwe-Ultrasonic noma kwe-solventukususa izinsalela ezilimazayo namafutha.

Ukuhlolwa kwe-metrological, okuhlanganisa:

Ububanzi nokujikeleza (igeji yomoya noma umshini wokulinganisa wokuhlanganisa)

Ubulukhuni bobuso (iphrofayili)

Ukuqondisa nokuphuma (isikhombi sokudayela noma ukuqondanisa kwe-laser)

Izingxenye ezihlangabezana nayo yonke imibandela yokunemba kuphela eziqhubekela ekucwecweni, ekuhlanganisweni, noma ekuhlanganiseni.

4. Izilinganiso Ezijwayelekile Zokuhlonishwa Zemiphini Eqondile

5. Izinzuzo Zokucija Ekwenziweni Kwe-Precision Shaft

Ikhwalithi Yobuso Ephakeme-Izindawo ezibushelelezi nezingamathafa zinciphisa ukungqubuzana nokuguga.

Ukunemba Okuphezulu Okuphezulu- Ivumela ukucindezelwa noma ukushelela kulingane ngokuvunyelwa okuncane.

Ukusebenza Kwezimpawu Okuthuthukisiwe- Ukuthungwa kwe-Crosshatch kugcina okokuthambisa futhi kuvimbela ukuvuza.

Amandla Okukhathala Athuthukisiwe- Isusa ama-microcracks kanye nezikhuphukeli zengcindezi ekugayeni.

Umsindo Oncishisiwe Nokudlidliza- Ukuqondisa okuthuthukisiwe nokujikeleza kukhuthaza ukujikeleza okushelelayo.

Impilo Yenkonzo Enwetshiwe- Ama-shafts amelana nokushaya amagoli, ukugabha, nokugqwala kangcono.
