Umhlahlandlela Ophelele Wezibambi Zethuluzi Lokushwabana Kokushisa: Ukusuka Ezimisweni Ze-Thermodynamic ukuya Ekulungisweni Okunembayo kwe-Sub-millimeter (Umhlahlandlela Osebenzayo ka-2025)
Kwembula Imfihlo Yokunemba Kwe-Runout engu-0.02mm: Imithetho Eyishumi Yokusebenzisa Imishini Yokunciphisa Ukushisa kanye Namasu Okwenza Kuphindwe kabili Ukuphila Kwabo
Uhlaka lwe-athikili:
I. Ithiyori eyisisekelo ye-thermodynamic ehilelekile emshinini wokunciphisa ukushisa: Ukusetshenziswa kwesimiso sokunwetshwa kwe-thermal kanye nokufinyela ekubambeni kwethuluzi.
1.Idatha Ebalulekile Kusayensi Yezinto:
I-alloy thermal expansion coefficient yesibambi:
Isibambo sethuluzi elishwabene lokushisa kwensimbi: α ≈ 11 × 10⁻⁶ / ℃ (inweba ngo-0.33mm lapho izinga lokushisa likhuphuka ngo-300℃)
Isimeli se-Hard alloy: α ≈ 5 × 10⁻⁶ / ℃
Idizayini yokulingana kokuphazamiseka:
ΔD=D0 . α. ΔT
Isibonelo: Isibambo sethuluzi esingu-φ10mm sishisisa sibe ngu-300℃ → Ububanzi bembobo bunwebeka ngo-0.033mm → Ngemva kokupholisa
Thola imvume efanelekile ye-0.01 - 0.03mm
2.Ukuqhathanisa Izinzuzo Zomshini Wobuchwepheshe Wokushisa Ukushisa:
| Indlela Yokubamba | Ukuphuma kobubanzi | I-Torque Transmission | Imvamisa Yohlelo Lokusebenza |
| I-Shrink Fit Holder | ≤3 | ≥100 | 50,000+ |
| Isibambi Sethuluzi le-Hydraulic | ≤5 | 400-600 | 35,000 |
| Iqoqo le-ER Spring | ≤10 | 100-200 | 25,000 |
II. Inqubo yokusebenza ejwayelekile yomshini wokunciphisa ukushisa
Isigaba 1: Ukushisa kuqala komshini wokunciphisa ukushisa
1.Ipharamitha isetha ifomula yegolide: Tset = α. D0ΔDtarget +25℃
Qaphela: 25℃ imele imajini yokuphepha (ukuvikela ukubuya kwezinto)
Isb: H6 grade interference fit 0.015mm → Setha izinga lokushisa ≈ 280℃
2.Izinyathelo zokusebenza zomshini wokushwabanisa
Faka ithuluzi → Faka isibambi emshinini wokunciphisa ukushisa
↓
Setha izinga lokushisa/isikhathi
↓
Khetha uhlobo lwesibambi emshinini wokunciphisa
↓
Uma isibambi senziwe ngensimbi, ukukhetha kungokulandelayo: 280 - 320 ℃ / 8 - 12 imizuzwana
Uma usebenzisa isibambo sensimbi ye-alloy: 380 - 420 ℃ / 5 - 8 imizuzwana
↓
Isexwayiso se-Shrink Fit Machine buzzer → Susa isibambi
↓
Ukupholiswa komoya / Okupholiswe ngamanzi ngaphansi kuka-80 ℃ (Lona umshini wethu wokunciphisa ukushisa opholile umoya:Shrink Fit Machine, umshini wokunciphisa ukushisa opholile ngamanzi ukukhiqizwa nokuhlola kuyaqhubeka efektri.)
↓
Ngemva kokuqedwa kokusebenza emshinini wokulinganisa onciphayo, inkomba yokudayela ingasetshenziswa ukukala ukudlidliza.
Isigaba sesi-2: Ukuphatha Okuphuthumayo Kwemishini Enciphayo
I-alamu yezinga lokushisa elingaphezu kokushisa: Inqamule ugesi ngokushesha → Isibambi samathuluzi sicwiliswa egumbini legesi engasebenzi ukuze kuphole
Ukunamathela kwethuluzi: Kushise futhi ku-150 ℃ bese usebenzisa isikhiphi sethuluzi esikhethekile ukuliphusha liphume nge-axially.
III. Umhlahlandlela Wokulungisa Okujulile Wemishini Yokunciphisa Okushisayo: Kusukela Ekugcinweni Kwansuku zonke Kwemishini Ye-Shrink Fit kuya Ekubikezelweni Okunephutha
1.Ishejuli Yokulungisa Yezingxenye Eziyinhloko Zomshini Wokufiphaza I-Shrink Fit
| Izingxenye Zomshini We-Fit Shrink | Isondlo Sansuku Zonke | Ivikela Kakhulu | Ukulungiswa kabusha konyaka |
| Ikhoyili ye-heater | Susa isikali se-oxide | Isilinganiso senani lokumelana (ukuchezuka ngaphansi noma okulingana no-5%) | Faka esikhundleni umkhono we-ceramic insulation |
| Inzwa yezinga lokushisa | Ukuqinisekisa kukhombisa iphutha (±3℃) | Ukulinganisa kwe-thermocouple | Thuthukisa imojuli yokulinganisa izinga lokushisa le-infrared |
| Uhlelo Lokupholisa | Hlola ukuthi ingcindezi yelayini yegesi ingu-≥0.6MPa | Hlanza amaphiko okuchitha ukushisa | Shintshanisa ishubhu lamanje le-eddy lomshini wokushwabana |
2.Isu lokwelula isikhathi sokuphila sabaphathi bamathuluzi afinyezwayo
Ukuqapha inombolo yemijikelezo yokushisa:
Impilo yesibambi se-Mewha ifinyeza: ≤ Imijikelezo engu-300 → Ngemva kokweqa lo mkhawulo, ubulukhuni buyehla bufike ku-HRC5. Isifanekiso sefomu lerekhodi lomnikazi we-shrink fit: I-ID yokubamba | Idethi | Izinga lokushisa | Ukubala Okuqoqiwe
Ukwelashwa kokunciphisa ukucindezelwa kwesibambi esifanelekile:
Ngemva kwemijikelezo engu-50 → bamba ku-250℃ ihora elingu-1 ukuze izinga lokushisa liqhume njalo → susa ama-microcracks
IV. Imininingwane Yokuphepha Yemishini Yokunciphisa Ukushisa kanye Nezimo Zephutha Ezibulalayo
1.Okwenziwe Okune Okuphezulu Nokungamele Okungamele Kusetshenziswe Umshini Wokufiphaza Ofanele:
Susa isibambo ngesandla(idinga udladla olumelana nokushisa okuphezulu)
Ukupholisa amanzi quenching (ukuvumela kuphela ukupholisa)
Ukushisa okungaphezulu kuka-400 ℃ ukuze kuqiniswe ingxubevange (okuholela ekukhuphuleni okusanhlamvu kanye nokuphuka kweblade)
2. Ukuhlaziywa Kwezimo Zephutha Zokusebenza Komshini Wokubamba Ofanele:
Isigameko sokuqhuma efekthri yezimoto:
Isizathu: Uketshezi oluyinsalela lokusika olusuka esibambi sethuluzi elinciphayo → Ukushisa kubangela ukuhwamuka nokuqhuma
Izinyathelo: Engeza indawo yokusebenzela yokuhlanza ngaphambili yesibambi sethuluzi elinciphayo + umtshina womswakama
V. Izimo zohlelo lokusebenza kanye neziphakamiso zokukhetha ze-Shrink Fit Machines:
| Uhlobo Lwenqubo | Uhlobo Lwesibambi Olunconyiwe | Ukucushwa komshini we-Shrink Fit |
| I-Aerospace titanium alloy | Isibambi sethuluzi le-carbide ende nencane | I-High-Frequency thermal induction heat (ngaphezu kuka-400 ℃) |
| High - speed ngokunemba okuqoshiwe of isikhunta | Isibambi sensimbi esifushane | Ukushisa kwe-infrared (320 ℃) |
| Ukulayisha ngokweqile | Isibambi sensimbi esiqinisiwe(BT50) | Ukungeniswa kwe-electromagnetic + Uhlelo lokupholisa amanzi |
Uma unezinhlelo zokuthenga umshini we-shrink fit, ungachofoza ku-"Shrink Fit Machine"noma"I-Shrink Fit Holder" ukuze ufake isixhumanisi futhi ubuke ulwazi oluningiliziwe. Noma ungaxhumana nathi ngqo.
