Mohato ka mohato: Ts'ebetso e felletseng ea crankshaft e hlalositsoe
Khetho ea thepa le tokisetso
Mokhoa oa ho etsa thepa e qapiloeng crankshaft e qala ka khetho e hlokolosi ea lisebelisoa tse tala. Li-alloys tsa tšepe tsa boemo bo holimo hangata li khethoa bakeng sa matla a tsona a phahameng, ho tiea le ho hanyetsa ho apara. Li-alloys tsena, tseo hangata li nang le likarolo tse kang chromium, nickel, le molybdenum, li khethiloe ka ho khetheha ho finyella litlhoko tse batloang ke li-crankshaft tse sebetsang hantle haholo. Hang ha thepa e khethiloe, e khaola ka hloko ho ea boholo bo hlokahalang. Ho etsa bonnete ba hore thepa e bonolo ho e etsa, e futhumatsoa pele ho mocheso o itseng. Ts'ebetso ena ea ho futhumatsa e ntlafatsa ts'ebetso ea tšepe, ho etsa hore ho be bonolo ho bopa tlas'a khatello e phahameng nakong ea mekhahlelo ea ho etsa. Tokisetso e nepahetseng ea thepa e tala ke ea bohlokoa, kaha e beha sethala sa ho hlahisa crankshaft e nang le thepa e lakatsehang ea mochine le bophelo bo bolelele.
Phetoho ea pele le ho bōptjoa
Ka mor'a hore thepa e chesoe esale pele, e kena karolong ea pele ea forging. Mothating ona, likhatiso tse kholo tsa haeteroliki li sebelisa matla a maholo ho bopa tšepe e futhumetseng hore e be sebopeho se makukuno se lekanang le moralo oa ho qetela oa crankshaft. Ts'ebetso ea pele ea ho qhekella e bohlokoa kaha e theha geometry ea motheo ea karolo mme e theha motheo oa sebopeho sa eona sa lijo-thollo tse kahare. Ho ikamahanya ha phallo ea lijo-thollo nakong ena ho bohlokoa bakeng sa matla a crankshaft, ho tšoarella, le ho hanyetsa mokhathala. Ka ho laola ka hloko matla le mocheso nakong ea sebōpeho sa pele, bahlahisi ba etsa bonnete ba hore thepa e qala ho nka litšobotsi tse hlokahalang bakeng sa ts'ebetso e nepahetseng tlas'a maemo a phahameng a khatello ea kelello.
Ho etsa ka nepo le ho ntlafatswa
Ka mor'a ho bōptjoa ha pele, crankshaft e fetela sethaleng se nepahetseng, moo e tsoelang pele ho ntlafatsoa. Karolong ena e mahlonoko, ho sebelisoa litlhaselo tse ngata ho karolo e sebelisang li-dies e entsoeng ka mokhoa o khethehileng, ho e etsa hore e be sebopeho sa eona sa ho qetela ka mamello e matla. Ts'ebetso e nepahetseng ea ho qhekella e netefatsa hore crankshaft e fihlella ho nepahala ha maemo le pheletso ea bokaholimo. Lisebelisoa tse tsoetseng pele tse laoloang ke k'homphieutha li atisa ho sebelisoa ho boloka botsitso le ho nepahala nakong eohle ea ts'ebetso, ho netefatsa hore crankshaft ka 'ngoe e finyella litekanyetso tse tiileng tsa boleng. Mokhahlelo ona ha o ntlafatse sebopeho sa karolo feela empa hape o ntlafatsa likarolo tsa ona tsa mochini, joalo ka matla a tsitsipano le ho hana mokhathala, ho lokisa crankshaft bakeng sa karolo ea eona e boima ea ts'ebetso.
Li-checkpoints tsa taolo ea boleng ho tlhahiso ea crankshaft forging
Tlhahlobo le tlhahlobo ea metallurgical
Tlhahlobo ea Metallurgical ke karolo ea bohlokoa ea taolo ea boleng nakong eohle ea ts'ebetso ea ho qhekella. Nakong ena, sebopeho le sebopeho sa thepa li netefatsoa ho netefatsa hore motsoako o nepahetseng o sebelisoa bakeng sa crankshaft. Sena se kenyelletsa ho netefatsa hore tšepe e na le tekanyo e nepahetseng ea likarolo tse kang carbon, chromium, nickel, le molybdenum, tse bohlokoa bakeng sa ho finyella matla a lakatsehang le ho hanyetsa mokhathala. Mefuta e fapaneng ea liteko tse sa senyeheng, joalo ka tlhahlobo ea ultrasonic le tlhahlobo ea likaroloana tsa makenete, li sebelisoa methating e fapaneng ho bona mefokolo ea kahare, mapetsong, kapa ho se lumellane ka har'a crankshaft e entsoeng. Mekhoa ena e netefatsa botšepehi ba thepa le hore sehlahisoa sa ho qetela se finyella litekanyetso tsa polokeho le ts'ebetso.
Netefatso ea dimensional le geometri
Hang ha ts'ebetso ea ho qhekella e phethiloe, faele ea crankshaft e fana ka netefatso e nepahetseng ea sebopeho le sebopeho sa geometri. Mohato ona o kenyelletsa ho sebelisa lisebelisoa tse tsoetseng pele tsa metrology ho nka litekanyo tse nepahetseng le ho netefatsa hore karolo e kopana le lintlha tse hlokahalang bakeng sa ts'ebetso ea eona. Likarolo tsa bohlokoa joalo ka li-diameter tsa koranta, libaka tsa phini, le bolelele ba kakaretso lia hlahlojoa ho netefatsa hore li oela ka har'a mamello e boletsoeng. Mamello ea li-geometric le tsona li netefalitsoe ho netefatsa hore tekano le tekano ea crankshaft li nepahetse. Tlhokomelo ena ea lintlha e netefatsa hore crankshaft e tla sebetsa hantle ka har'a enjene, e fokotsa kotsi ea ho thothomela, ho senyeha le ho hloleha.
Ketsiso ea ts'ebetso le tlhahlobo ea khatello ea maikutlo
Pele ho tumello ea ho qetela le ho lokolloa ts'ebetsong, crankshaft e entsoeng e etsoa lipapiso tsa ts'ebetso le tlhahlobo ea khatello ea maikutlo. Mekhoa e tsoetseng pele ea ho etsa mohlala oa likhomphutha e sebelisoa ho etsisa maemo a fapaneng a ts'ebetso, joalo ka meroalo e phahameng, mocheso le lebelo la ho potoloha. Lipapiso tsena li thusa ho bolela esale pele hore na crankshaft e tla sebetsa joang tlas'a maemo a sebele a lefats'e le ho tseba mathata leha e le afe a ka bang teng, joalo ka libaka tsa khatello e feteletseng kapa ho thothomela. Ka ho etsa tlhahlobo ena ea sebele, lienjiniere li ka etsa liphetoho tse hlokahalang moralong pele crankshaft e lekoa 'meleng, ho etsa bonnete ba hore e tla sebetsa hantle le ka ts'epo bophelong bohle ba eona ba ts'ebeletso.
