Umhlobiso wezakhiwo, imikhiqizo yasendlini yomphakathi inaka kakhulu umphumela wokubumba ukubukeka nokusebenza kwezindleko, izidingo zamandla amaphakathi.I-aluminium engu-6063 yochungechunge ine-ductility enhle kakhulu kanye nokuthungwa kwendawo enhle, okuyinto ekhethwayo yalolu hlobo lwephrojekthi.
Izimo eziyisisekelo zokuphepha njengemoto nokundiza zidinga ukusebenza kwempahla ephezulu kakhulu. Ama-alloys akhethekile ane-balanced ductility namandla esakhiwo azokhethwa ukuze kuqinisekiswe ukumuncwa kwamandla okushayisana namandla okuzamazama komhlaba kwamaphrofayili futhi kuthuthukiswe ukuphepha kukonke kwemikhiqizo.

I-Bonding Material State Selection

Esigabeni sokwakheka sokucubungula iphrofayili, izinto ze-aluminium ze-O-state kanye ne-T4-state high-plasticity zikhethwa ukuthi ziqedele kalula izinqubo zokubumba eziyinkimbinkimbi. Ngemuva kokubumba, amandla athuthukiswa ngokwelashwa kokuguga, kucatshangelwa ukusebenziseka kalula kokucubungula nokusebenzisa ukuzinza.
Lapho ukhetha izinto zokwakha, ungalandeli ngobumpumputhe i-aluminium enamandla amakhulu kanye nesimo sokuqina okuphezulu, ngoba i-ductility yezinto ezinjalo impofu kakhulu. Kulula ukuchithwa kunqubo yokucubungula, noma ukuphuka okuphukayo ekusetshenzisweni kamuva, okufinyeza kakhulu impilo yesevisi yomkhiqizo.

Cukufakwa

I-Ductility iyindawo eyinhloko ewumshini enquma ikhono lokucubungula kanye nenani le-aluminum letheminali, elithintwa izici eziningi ezifana nefomula yengxubevange, inqubo yokwelapha ukushisa kanye nemingcele yokucubungula. Futhi ukusebenza ngakunye kungalungiswa ngokunembile futhi kulungiselelwe ngobuchwepheshe bemanuwali. Izinga lokukhethwa kwezinto ezibonakalayo kanye nohlelo lokuthuthukisa ukukhiqizwa lokulawula ngokunembile i-ductility ye-aluminium ayikwazi nje ukuthuthukisa ngempumelelo ukusebenza kahle kokucubungula, ukunciphisa izindleko zokulahlekelwa kokukhiqiza, kodwa futhi ngokuqhubekayo bandise izimo zohlelo lokusebenza olusezingeni eliphezulu lwamaphrofayili e-aluminium ekukhiqizeni okuphezulu, amandla amasha nezinye izimboni.
