ISikhokelo esiBanzi seZixhobo zeSixhobo sokuHlukana koBushushu: Ukusuka kwiMigaqo ye-Thermodynamic ukuya kwi-Sub-millimeter Precision Maintenance (Isikhokelo esiSebenzayo sika-2025)
Ukutyhila iMfihlo ye-0.02mm yokuLuleka kokuLuleka: iMithetho eliShumi yokuSebenzisa oomatshini bokucutha ubushushu kunye namaqhinga okuPhinda kabini ubomi babo.
Ulwandlalo lwenqaku:
I. Ithiyori ye-thermodynamic esisiseko ebandakanyekayo kumatshini wokucutha ubushushu: Ukusetyenziswa komgaqo wokwandiswa kwe-thermal kunye nokucutha ekubambeni isixhobo.
1.IDatha ePhambili kwiNzululwazi yeMpahla:
Ingxubevange yokwandiswa kwe-thermal coefficient yesibambi:
Umqheba wesixhobo sokushwabana sobushushu bentsimbi: α ≈ 11 × 10⁻⁶ / ℃ (ukwanda nge-0.33mm xa ubushushu bunyuka nge-300℃)
Isibambi sesixhobo se-Hard alloy: α ≈ 5 × 10⁻⁶ / ℃
Uyilo longenelelo olufanelekileyo:
ΔD=D0 . α. ΔT
Umzekelo: Isiphatho sesixhobo se-φ10mm sifudunyezwa ukuya kuma-300℃ → Idayamitha yomngxuma iyanda nge-0.033mm → Emva kokupholisa
Ukufumana imvume efanelekileyo ye-0.01 - 0.03mm
2.Ukuthelekiswa kwezinto eziluncedo kumatshini wobuChwephesha bokuBuyisa ubushushu:
| Indlela yokuBamba | I-Dimeter Runout | Ukuhanjiswa kweTorque | Ukuphindaphinda kwesicelo |
| Shrink Fit Holder | ≤3 | ≥100 | 50,000+ |
| Isibambi seSixhobo seHydraulic | ≤5 | 400-600 | 35,000 |
| ER Spring Qokelela | ≤10 | 100-200 | 25,000 |
II. Inkqubo yokusebenza esemgangathweni kumatshini wokunciphisa ubushushu
Isigaba 1: Ukufudumeza ubushushu bomatshini wokunciphisa ubushushu
1.Iparamitha yokumisela ifomyula yegolide: Tset = α. D0ΔIthagethi +25℃
Qaphela: i-25℃ imele umda wokhuseleko (ukuthintela ukubotshwa kwezinto)
Umz: uphazamiseko lwebakala H6 lulingana 0.015mm → Seta ubushushu ≈ 280℃
2.Amanyathelo okusebenza omatshini wokushwabana ofanelekileyo
Faka isixhobo → Faka isibambi kumatshini wokunciphisa ubushushu
↓
Seta ubushushu/ixesha
↓
Khetha uhlobo lwesibambi kumatshini wokucutha ofanelekileyo
↓
Ukuba umnini wenziwe ngentsimbi, ukhetho lulandelayo: 280 - 320 ℃ / 8 - 12 imizuzwana
Ukuba usebenzisa umqheba wentsimbi yealloyi: 380 - 420 ℃ / 5 - 8 imizuzwana
↓
Isilumkiso soShishino oLungileyo sebuzzer → Susa isibambi
↓
Ukupholisa umoya / Ukupholiswa kwamanzi ngaphantsi kwe-80 ℃ (Lo ngumatshini wethu wokucutha ubushushu obupholileyo:Shrink Fit Machine, umatshini wokucutha ubushushu obupholileyo ngamanzi ukuveliswa kunye novavanyo luyaqhubeka kumzi-mveliso.)
↓
Emva kokuba usebenziso kumatshini we-shrink fit ugqityiwe, isalathisi sokudayela singasetyenziselwa ukulinganisa ukungcangcazela.
Inqanaba lesi-2: UkuPhathwa okuNgxamisekileyo koomatshini abashwabeneyo abafanelekile
I-alam yobushushu obugqithisileyo: Cima umbane ngoko nangoko → Umphathi wesixhobo untywiliselwa kwigumbi lerhasi engasebenziyo ukuze aphole.
Isixhobo sokuncamathelisa: Yitshise kwakhona ukuya kwi-150℃ kwaye emva koko usebenzise isixhobo esikhethekileyo sokususa isixhobo ukuyityhala ngaphandle nge-axially.
III. Isikhokelo soLondolozo oluNzulu koomatshini bokuTshina beThermal: Ukusuka kuLondolozo lweMihla le koomatshini abaHluphekileyo ukuya kwiFault Prediction
1.IShedyuli yoLondolozo lweMicimbi enguNdoqo yoMshini we-Shrink Fit
| Shrink Fit Machine Components | ULondolozo lweMihla | Ikhusela Kakhulu | Uhlengahlengiso lonyaka |
| Ikhoyili yesifudumezi | Susa isikali se-oxide | Umlinganiselo wexabiso lokuchasa (ukutenxa ngaphantsi okanye ukulingana no-5%) | Tshintsha umkhono we-ceramic insulation |
| Isivamvo sobushushu | Uqinisekiso lubonisa impazamo (±3℃) | Ukulinganisa kwe-thermocouple | Ukuphucula imodyuli yokulinganisa ubushushu be-infrared |
| Inkqubo yokupholisa | Khangela ukuba uxinzelelo lwegesi luyi-≥0.6MPa | Coca amaphiko okuchitha ubushushu | Buyisela ityhubhu ye-eddy yangoku yomatshini wokushwabana wokungena |
2.Isicwangciso-qhinga sokwandisa ubomi babaxhobisi bezixhobo ezicuthekayo
Ukubeka iliso kwinani lemijikelo ye-thermal:
I-Mewha shwabanisa ubomi bomphathi wesixhobo esifanelekileyo: ≤ Imijikelo engama-300 → Emva kokugqithisa lo mda, ukuqina kuyehla ukuya kwi-HRC5. Ithempleyithi yefomu yerekhodi yomphathi ocuthekayo: Handle ID | Umhla | Ubushushu | Ubalo olongezelekayo
Unyango lokunciphisa uxinzelelo lomphathi ophantsi:
Emva kwemijikelo engama-50 → bamba kuma-250℃ kangangeyure e-1 ukuze ubushushu buqhubeke → susa ii-microcracks
IV. IiNkcazo zoKhuseleko kuMatshini wokuNciphisa uBushushu kunye neemeko zeempazamo eziFatal
1.Izinto ezine eziphezulu zokwenziwa nokungaWenziyo ngokuSebenzisa umatshini wokuShrink Fit:
Susa umqheba ngesandla(ifuna ipliers ekwaziyo ukumelana nobushushu)
Ukucima ukupholisa kwamanzi (kukuvumela kuphela ukupholisa)
Ukufudumeza ngaphezulu kwe-400℃ ukwenza lukhuni ialloyi (okukhokelela ekukhuleni kweenkozo kunye nokuqhekeka kweblade)
2. Uhlalutyo lweemeko zokuSebenza kweeMposiso zoMtshini we-Shrink Fit:
Isiganeko sogqabhuko-dubulo kumzi-mveliso weemoto:
Isizathu: Ulwelo olushiyekileyo lokusika olusuka kwisibambi sesixhobo sokushwabana → Ukufudumala kubangela ukuba kubekho umphunga kunye nogqabhuko-dubulo.
Amanyathelo: Yongeza indawo yokusebenzela yokucoca kwangaphambili yesibambi sesixhobo esicuthekayo + nesikhangeli sokufuma
V. Iimeko zeSicelo kunye neeNgcebiso zokuKhetha oomatshini abaFityiswayo bokuShrink:
