Mekhoa ea tekheniki ea ho sebetsa likarolo tsa aluminium alloy
1) Khetho ea datum ea ho sebetsa
Lintlha tsa ts'ebetso li lokela ho lumellana ka hohle kamoo ho ka khonehang le datum ea meralo, palo ea kopano le datum ea tekanyo, 'me botsitso, ho nepahala ha maemo le ho tšepahala ha likarolo li lokela ho nkoa ka botlalo ho thekeniki ea ho sebetsa.
2) Ho sebetsa ka thata
Hobane ho nepahala ha dimensional le bokaholimo ba likarolo tse ling tsa alloy alloy ha ho bonolo ho fihlela litlhoko tse phahameng tse nepahetseng, likarolo tse ling tse nang le libopeho tse rarahaneng li hloka ho ts'oaroa pele li sebetsoa, 'me li kopantsoe le litšobotsi tsa lisebelisoa tsa alloy tsa aluminium bakeng sa ho itšeha.Mocheso o hlahisoang ka tsela ena o tla lebisa ho deformation ea ho itšeha, liphoso tse fapaneng ka boholo ba likarolo, esita le ho lebisa ho deformation ea workpiece.Ka hona, bakeng sa ka kakaretso sefofane kaba sila sebetsa.Ka nako e ts'oanang, mokelikeli o pholileng o eketsoa ho pholisa workpiece ho fokotsa tšusumetso ea ho khaola mocheso ka ho nepahala ha machining.
3) Qetella machining
Nakong ea ts'ebetso, ho itšeha ka lebelo le phahameng ho tla hlahisa mocheso o mongata, le hoja litšila li ka tlosa mocheso o mongata, empa li ntse li ka hlahisa mocheso o phahameng ka ho fetisisa ka lehare, hobane ntlha ea ho qhibiliha ha aluminium e tlaase, lehare. hangata e boemong ba ho qhibiliha, e le hore matla a ho itšeha a angoa ke mocheso o phahameng, ho bonolo ho hlahisa likarolo tsa motsoako oa aluminium nakong ea ho etsa liphoso tsa concave le convex.Ka hona, ts'ebetsong ea ho qeta, hangata khetha mokelikeli oa ho itšeha o nang le ts'ebetso e ntle ea ho pholisa, ts'ebetso e ntle ea lubrication le viscosity e tlase.Ha lisebelisoa tsa ho tlotsa, mocheso oa ho itšeha o tlosoa ka nako ho fokotsa mocheso oa holim'a lisebelisoa le likarolo.
4) Khetho e utloahalang ea lisebelisoa tsa ho itšeha
Ha ho bapisoa le litšepe tse nang le tšepe, matla a ho itšeha a hlahisoang ke motsoako oa aluminium o batla o le monyenyane ka mokhoa oa ho itšeha, 'me lebelo la ho itšeha le ka ba holimo, empa ho bonolo ho etsa li-nodule tsa litšila.Thermal conductivity ea aluminium alloy e phahame haholo, hobane mocheso oa litšila le likarolo tsa mokhoa oa ho itšeha o phahame, mocheso oa sebaka sa ho itšeha o tlase, ho tšoarella ha sesebelisoa ho phahame, empa ho phahama ha mocheso oa likarolo ka botsona. e potlakile, e bonolo ho baka deformation.Ka hona, ho sebetsa haholo ho fokotsa matla a ho itšeha le ho khaola mocheso ka ho khetha sesebelisoa se nepahetseng le sekhutlo se loketseng sa lisebelisoa le ho ntlafatsa ho hlaka holim'a lisebelisoa.
5) Sebelisa phekolo ea mocheso le phekolo e batang ho rarolla deformation ea ho sebetsa
Mekhoa ea phekolo ea mocheso ho felisa khatello ea mechine ea lisebelisoa tsa aluminium alloy e kenyelletsa: nako ea maiketsetso, recrystallization annealing, joalo-joalo Tsela ea ts'ebetso ea likarolo tse nang le mohaho o bonolo o amoheloa ka kakaretso: ho sebetsa ka thata, ho sebetsa ka nako ea matsoho, ho qeta machining.Bakeng sa tsela ea likarolo tse nang le mohaho o rarahaneng, hangata e sebelisoa: ho sebetsa ka thata, ho sebetsa ka nako ea maiketsetso (phekolo ea mocheso), ho qeta nako e lekaneng, ho sebetsa ka nako ea maiketsetso (phekolo ea mocheso), ho qeta mechine.Le hoja ts'ebetso ea maiketsetso ea nako (phekolo ea mocheso) e hlophisitsoe ka mor'a ho sebetsa ka thata le ho qeta halofo ea ho qeta, mokhoa o tsitsitseng oa phekolo ea mocheso o ka hlophisoa ka mor'a ho qeta ho sebetsa ho thibela liphetoho tse nyenyane nakong ea ho kenya likarolo, ho kenya le ho sebelisoa.
Litšobotsi tsa ts'ebetso ea likarolo tsa aluminium alloy process
1) E ka fokotsa tšusumetso ea khatello ea maikutlo e setseng ho deformation ea machining.Kamora ho sebetsa ka thata, ho khothaletsoa ho sebelisa kalafo ea mocheso ho tlosa khatello ea maikutlo e hlahisoang ke machining a thata, e le ho fokotsa tšusumetso ea khatello ho boleng ba mochini oa ho qetela.
2) Ntlafatsa ho nepahala ha machining le boleng bo holimo.Ka mor'a karohano ea mechine e thata le ea ho qetela, ho qeta ho sebetsa ho na le chelete e nyenyane ea ho sebetsa, ho sebetsana le khatello ea kelello le deformation, e ka ntlafatsang haholo boleng ba likarolo.
3) Ntlafatsa katleho ea tlhahiso.Kaha machining a thata a tlosa feela lintho tse feteletseng, a siea moeli o lekaneng bakeng sa ho qeta, ha a nahane ka boholo le mamello, ka katleho ho fana ka papali ho ts'ebetsong ea mefuta e fapaneng ea lisebelisoa tsa mochine le ho ntlafatsa katleho ea ho itšeha.
Ka mor'a hore likarolo tsa alloy aluminium li khaotsoe, mohaho oa tšepe o tla fetoloa haholo.Ho phaella moo, phello ea ho khaola ho sisinyeha ho lebisa khatellong e kholo ea masala.E le ho fokotsa deformation ea likarolo, khatello e setseng ea thepa e lokela ho lokolloa ka botlalo.
