Tataiso e Pharalletseng ea Lits'oants'o tsa Lisebelisoa tsa Mocheso: Ho Tloha ho Melao-motheo ea Thermodynamic ho ea ho Tlhokomelo e nepahetseng ea limilimithara tse ka tlase (Tlhahiso e sebetsang ea 2025)
Ho Utulla Lekunutu la 0.02mm Runout Precision: Melao e Leshome ea ho Sebelisa Mechini ea Mocheso oa Mocheso le Maano a ho Pheta Nako ea Bophelo ba Bona
Kemiso ea Sengoloa:
I. Thermodynamic fundamental theory e amehang mochining oa ho honyela mocheso: Tšebeliso ea molao-motheo oa katoloso ea mocheso le ho honyela ha mochini o honyetsang mocheso.
Lintlha tsa 1.Key ho Saense ea Lintho:
Alloy thermal katoloso coefficient ea se ts'oereng:
Sesebelisoa sa tšepe se honyehang: α ≈ 11 × 10⁻⁶ / ℃ (e atoloha ka 0.33mm ha mocheso o nyoloha ka 300℃)
Sesebelisi sa motsoako o thata: α ≈ 5 × 10⁻⁶ / ℃
Moralo o loketseng tšitiso:
ΔD=D0 . α. ΔT
Mohlala: Motsoako oa sesebelisoa oa φ10mm o futhumatsoa ho isa ho 300℃ → Bophara ba lesoba bo hola ka 0.033mm → Kamora ho pholile
Fumana tumello e loketseng ea 0.01 - 0.03mm
2.Papiso ea Melemo ea Theknoloji ea Mochini oa Mocheso o Fokotsang Mocheso:
| Mokhoa oa ho koala | Diameter Runout | Phetiso ea Torque | Khafetsa ea Kopo |
| Shrink Fit Holder | ≤3 | ≥100 | 50,000+ |
| Hydraulic Tool Holder | ≤5 | 400-600 | 35,000 |
| ER Spring Bokella | ≤10 | 100-200 | 25,000 |
II. Mokhoa o tloaelehileng oa ts'ebetso bakeng sa mochini o fokotsang mocheso
Mohato oa 1: Preheating ea mochini o fokotsang mocheso
1.Parameter e beha mokhoa oa khauta: Tset = α. D0ΔDtarget +25℃
Tlhokomeliso: 25 ℃ e emela moeli oa polokeho (ho thibela ho khutla ha thepa)
Mohlala: tšitiso ea sehlopha sa H6 e lekana 0.015mm → Seta mocheso ≈ 280℃
2.Operating mehato ea shrink fit mochine

Kamora hore ts'ebetso ea mochini oa shrink fit e phetheloe, ho ka sebelisoa sesupo sa ho daela ho lekanya ho thothomela.
Mokhahlelo oa 2: Ts'ebetso ea Tšohanyetso ea Mechini e loketseng ho honyela
Alamo e nang le mocheso o feteletseng: Hang-hang ho khaola phepelo ea motlakase → Sets'oants'o sa sesebelisoa se qoelisoa ka phaposing ea khase e sa sebetseng hore e phole.
Ho khomarela lisebelisoa: E chese hape ho 150 ℃ ebe u sebelisa sesebelisoa se khethehileng sa ho tlosa lisebelisoa ho e sutumelletsa ka ntle ka axially.
III. Tataiso e Tebileng ea Tlhokomelo bakeng sa Mechini e Fokotsang Mocheso: Ho Tloha ho Tlhokomelo ea Letsatsi le Letsatsi ea Mechini ea Shrink Fit ho ea Bokhopong ba Phoso.
1.Kemiso ea Tlhokomelo bakeng sa Likarolo tsa Core tsa Shrink Fit Machine
| Shrink Fit Machine Components | Tlhokomelo ea Letsatsi le Letsatsi | E Sireletsa Haholo | Phetoho ea Selemo le Selemo |
| Koala ea Heater | Tlosa sekala sa oxide | Tekanyo ea boleng ba khanyetso(ho kheloha ka tlase ho kapa ho lekana le 5%) | Kenya sebaka sa sekontiri sa ceramic |
| Sensor ea mocheso | Netefatso e bontša phoso (± 3℃) | Tekanyo ea thermocouple | Ntlafatsa mojule oa tekanyo ea mocheso oa infrared |
| Mokhoa oa ho Pholisa | Sheba hore na khatello ea khase ea khase ke ≥0.6MPa | Hloekisa mapheoana a ho qhala mocheso | Kenya sebaka sa tube ea eddy ea mochini oa shrink fit |
2.Leano la ho lelefatsa nako ea bophelo ea batho ba nang le lisebelisoa tse honyehang
Tlhokomelo ea palo ea lipotoloho tsa mocheso:
Nako ea bophelo ea sets'oants'o sa sesebelisoa sa Mewha shrink fit: ≤ 300 cycles → Kamora ho feta moeli ona, boima bo theohela ho HRC5. Sebopeho sa foromo ea rekoto ea ho nyenyefatsa: Tšoara ID | Letsatsi | Mocheso | Kakaretso Palo
Kalafo ea ho imolla khatello ea kelello ea Shrink fit holder:
Ka mor'a lipotoloho tse ling le tse ling tse 50 → tšoara ho 250 ℃ bakeng sa hora e le 'ngoe bakeng sa mocheso o sa khaotseng oa mocheso → tlosa li-microcracks
IV. Litlhaloso tsa Polokeho Bakeng sa Mechini e Fokolang Mocheso le Maemo a Phoso a Bolaeang

Tlosa mofeng ka letsoho (e hloka pliers e hanyetsanang le mocheso o phahameng)
Ho tima metsi a pholileng (ho lumella feela ho pholile)
Ho futhumatsa ka holimo ho 400 ℃ ho thatafatsa motsoako (ho fella ka ho hohola ha lijo-thollo le ho robeha ha lehare)
2. Tlhahlobo ea Linyeoe tsa Ts'ebetso ea Phoso ea Mochini oa Shrink Fit:
Ketsahalo ea ho phatloha femeng ea likoloi:
Lebaka: Mokelikeli o setseng oa ho itšeha ho tsoa ho sets'oants'o sa sesebelisoa se nyenyefatsang → Ho futhumatsa ho baka mouoane le ho phatloha
Mehato: Eketsa sebaka sa ho sebetsa sa ho hloekisa pele bakeng sa sets'oants'o sa lisebelisoa tse nyenyefatsang + mochini o bonang mongobo
V. Maemo a Kopo le Litlhahiso tsa Khetho bakeng sa Mechini ea Shrink Fit:
| Mofuta oa Ts'ebetso | E khothalelitsoeng Mofuta oa Motšoantšisi | Shrink Fit Machine Configuration |
| Aerospace titanium alloy | Sets'oants'o sa lisebelisoa tsa carbide tse telele le tse tšesaane | Ho futhumatsa ha mocheso o phahameng oa maqhubu a phahameng (ka holimo ho 400 ℃) |
| High - lebelo precision fatiloeng ea hlobo | Sets'oants'o sa tšepe se khuts'oane sa conical | Ho futhumatsa ha infrared (320 ℃) |
| Ho ba le moroalo o mongata | Sets'oants'o sa tšepe se matlafalitsoeng(BT50) | Electromagnetic induction + Sistimi ea ho futhumatsa metsi |
Haeba u na le merero ea ho reka mochini o nyenyefatsang, o ka tobetsa "Mochini oa Fihla oa Shrink"kapa"Shrink Fit Holder" ho kenya sehokelo le ho sheba lintlha tse felletseng. Kapa o ka ikopanya le rona ka kotloloho.
