Melao-motheo ea Bohlokoa bakeng sa ho Theha Li-Forging tse Ntle
1. Khetha Boitsebiso bo Nepahetseng
Boleng ba ho betla bo qala ka khetho e nepahetseng ea thepa. Hase litšepe tsohle tse loketseng ho betla, 'me e' ngoe le e 'ngoe e na le litšobotsi tse fapaneng tsa ho betla.
Lisebelisoa tse tloaelehileng tsa ho betla:
-
Tšepe ea k'habone: Ho khona ho tšoarella hantle le litšenyehelo tse tlase
-
Tšepe ea motsoako: Matla le ho tiea ho matlafalitsoeng
-
Ts'epe e sa beng le mabali: Ho hanyetsa mafome, ho hloka ho futhumatsoa ho laoloang
-
Titanium: E bobebe, e matla, empa e hloka taolo e nepahetseng ea mocheso
-
Li-alloy tsa nikeli: Ho hanyetsa mocheso o phahameng, ho loketse bakeng sa sefofane le matla
Ho sebetsa le mofani oa thepa ea tšepahalang joalo kasakysteele netefatsa hore thepa e tala e fihlela maemo a machaba mme ha e na diphoso.
2. Utloisisa Mefuta ea Mocheso oa ho Theha
Tšepe e 'ngoe le e 'ngoe e na le mocheso o itseng bakeng sa ho betla. Ho betla ho chesa haholo ho ka baka ho korotla kapa ho oxidation, ha ho betla ho bata haholo ho ka lebisa ho petsoheng.
| Thepa | Sebaka sa Mocheso oa ho Theha (°C) |
|---|---|
| Tšepe ea Khabone | 1050 – 1250 |
| Ts'epe e sa beng le mabali | 1000 – 1200 |
| Tšepe ea motsoako | 950 – 1200 |
| Li-alloy tsa Titanium | 800 – 950 |
| Litšepe tse kopantsoeng tsa Inconel | 980 – 1175 |
Sebelisa li-pyrometer le li-control tse iketsang ho boloka mocheso o nepahetseng nakong ea ts'ebetso ea ho betla.
3. Netefatsa ho Futhumatsa ho Tšoanang
Ho futhumatsa ho sa lekanang ho lebisa ho feto-fetoha ho sa lekanang, ho petsoha le khatello ea ka hare. Sebelisa mekhoa e latelang:
-
Chesa lifono ka ho lekana pele o kenya
-

-
Sebelisaho futhumatsa ka inductionbakeng sa ho futhumatsa sebakeng se itseng le se laoloang
-
Qoba ho chesa haholo, e leng se ka bakang ho tlosoa ha khase kapa ho thehoa ha sekala
4. Sebelisa Moralo o Loketseng oa Die le Setlolo
Ha ho etsoa die forging e koetsoeng, moralo wa die o bohlokwa bakeng sa phallo ya tshepe le ho nepahala ha dibopeho.
Lintho tse lokelang ho nahanoa ka moralo oa life:
-
Kenya li-fillets le radii ho fokotsa khatello ea maikutlo
-
Qoba likhutlo tse bohale
-
Moralo oa phallo e leka-lekaneng ea tšepe ho thibela ho putlama kapa ho se be le letho
Etsa kopolitlolo tsa ho betla(jwalo ka dikobo tse thehilweng ho graphite kapa ceramic) ho fokotsa kgohlano, ho thibela ho kgomarela, le ho ntlafatsa bophelo ba ho tjhesa.
5. Laola Sekhahla sa Phetoho
Ho fetoha ha sebopeho ka potlako haholo kapa butle haholo ho ka baka diphoso.
-
Sebelisaho otla hanyane ka makhetlo a mangataho e-na le e le 'ngoe e boima
-
Boloka sekhahla se tsitsitseng sa khatello
-
Sebelisa mechine e hatellang ea haeteroliki kapa ea sekurufu bakeng sa khatello e laoloang, e tšoanang
-
Fokotsa ho otloa ho sa lokelang ho ba teng bohareng ho qoba ho sotha
Ho feto-fetoha ho nepahetseng ho ntlafatsa phallo ea lijo-thollo le ho eketsa ho tiea ha likarolo.
6. Lekola le ho Fokotsa Oxidation
Ho ntsha oksijene ke bothata bo tlwaelehileng ho tjheseng e chesang. E fokotsa boleng ba bokahodimo mme e lebisa tahlehelong ya thepa.
Ho fokotsa oxidation:
-
Sebelisa masela a sireletsang pele o futhumatsa
-
Sebelisa litsamaiso tsa ho futhumatsa tsa khase e sa sebetseng kapa tsa vacuum
-
Fokotsa nako ea ho pepesehela mocheso o phahameng
-
Hloekisa thepa e tala pele u e betla
sakysteele sebelisa theknoloji e tsoetseng pele ea sebōpi le mekhoa ea ho thibela oxidation ho fana ka li-forging tse hloekileng le tse nepahetseng.
7. Etsa Mekhoa ea Kalafo ea Kamora ho Fehla
Ho qapa lintho hantle ha ho felle feela ho boralitaba — ho qapa lintho ka mor'a ho sebetsa ho bohlokoa ka ho tšoanang.
-
Ho kutaTlosa flash kapa thepa e feteletseng
-
Kalafo ea mocheso: Ntlafatsa matla, ho tsitsa le ho tiea
-
Ho etsa hore ho be le maemo a tloaelehileng kapa ho annealing: Ntlafatsa sebopeho sa lijo-thollo
-
Ho phatloha kapa ho phunya dithunya: Hloekisa bokaholimo
-
Ho etsa mechini: Finyella ho nepahala ha tekanyo ea ho qetela
-
Teko ea ultrasound kapa ea makenete: Lemoha mefokolo ea ka hare
Ho sebetsa ka likheo tse entsoeng ka forged ho tsoa hosakysteel, bareki ba ka fumana likarolo tse seng li ntse li hlophisitsoe hantle, li kentsoe ka har'a anneal, kapa li entsoe ka mokhoa o sa lokelang ho boloka nako ea ts'ebetso.

Qetello
Ho betla li-forging tse ntleke saense le bonono. E hloka thepa e nepahetseng, ho futhumatsa ho laolehileng, ho fetola sebopeho sa setsebi, ho sebetsana le lintho ka mor'a ho sebetsa, le ho netefatsa boleng. Ha e etsoa ka nepo, ho betla ho fana ka matla a phahameng, ho tiea le ho tšepahala bakeng sa likarolo tsa bohlokoa.
Hore na o betla dikarolo tse nyane tse nepahetseng kapa dikarolo tse kgolo tsa sebopeho, mekgwa e nepahetseng - le mofani ya nepahetseng - e etsa phapang yohle. Ka boiphihlelo bo tebileng le bokgoni bo tswetseng pele,sakysteele thusa bareki ho atleha ka ho qapa ho hong le ho hong.
Haeba o batla likarolo tsa boleng bo holimo tse entsoeng ka maiketsetso tse nang le ts'ebetso e tsitsitseng, ikopanye lesakysteelho hlahloba ditharollo tse ikgethileng tse etseditsweng projeke ya hao.
