Aluminium billets amatanthauza chinthu chomaliza chopangidwa ndi aluminiyamu chomwe nthawi zambiri chimakhala chowoneka ngati cylindrical kapena rectangular.Billet nthawi zambiri amapangidwa kudzera mu njira yotchedwa casting, yomwe zitsulo zosungunuka zimatsanuliridwa mu nkhungu ndikuloledwa kuziziritsa ndi kulimba mu mawonekedwe omwe akufuna.
Ma Billets ali ndi ntchito zambiri m'makampani opanga zinthu chifukwa cha kusinthasintha kwawo komanso kukhazikika.Amagwiritsidwa ntchito kupanga mitundu ingapo ya zida zamakina monga mapaipi, ndodo, mabawuti, ndi shafts.Billet nthawi zambiri imayikidwa pa makina a lathe omwe amazungulira zinthuzo motsutsana ndi chida chodula kuti amete zinthuzo ndikupanga mawonekedwe omwe akufuna.Njira imeneyi imatchedwa kutembenuka, ndipo imagwiritsidwa ntchito pazochitika zomwe zimafunika kulondola kwambiri kapena pazinthu zomwe sizingapangidwe mwanjira ina iliyonse.Billet ikatembenuzidwa, imakonzedwanso pogwiritsa ntchito makina a CNC (Computer Numerical Control) - makina okonzedwanso omwe amagwiritsa ntchito mapulogalamu apakompyuta kuti azitha kuyendetsa komanso kuthamanga kwa zida.Potsirizira pake, billet imadulidwa muzidutswa zing'onozing'ono, ndipo zigawozo zimapatsidwa ntchito yomaliza kukonzekera msonkhano.
Tiyeni tiwone momwe ma billets amapangidwira.Njirayi imayamba ndi kuchotsa zinthu zopangira, zomwe zimasungunuka ndikuponyedwa mumitundu yomaliza.Nayi kulongosola pang'onopang'ono kwa njira zopangira:
Khwerero 1: Kusankha ndi Kuchotsa Zida Zopangira
Njirayi imayamba ndi kusankha kwa zipangizo.Aluminium billets nthawi zambiri amapangidwa kuchokera ku zinyalala za aluminiyamu kapena aluminium yoyamba.Kusankha kwa zopangira kumatengera zinthu monga mtengo, kapangidwe ka aloyi yomwe mukufuna, komanso kupezeka.
Gawo 2: Kusungunula ndi kuyenga
Zopangira zikachotsedwa, zimasungunuka mu ng'anjo kuti zichotse zonyansa ndikupanga mawonekedwe ofanana.Kuchita zimenezi kumadziwika kuti kusungunula, ndipo kumaphatikizapo kutentha zinthuzo mpaka zitasungunuka.Pambuyo posungunula, zinthuzo zimayengedwa kuti zipange chitsulo choyera.Njirayi imaphatikizapo kuchotsa zonyansa zilizonse zotsalira ndikusintha mankhwala achitsulo kuti akwaniritse zomwe akufuna.
Khwerero 3: Kupanga Billet
Chitsulocho chikayeretsedwa, chimaponyedwa mu mawonekedwe a billet.Izi zimaphatikizapo kuthira chitsulo chosungunulacho mu nkhungu, momwe chimazizira ndi kulimba kuti chikhale chachitali chooneka ngati cylindrical.Billet ikalimba, imachotsedwa mu nkhungu ndikutumizidwa ku mphero.Pa mphero, billet imatenthedwanso ndikudutsa muzitsulo zingapo kuti muchepetse m'mimba mwake ndikuwonjezera kutalika kwake.Izi zimapanga mankhwala omaliza omwe amatha kusinthidwa kukhala mawonekedwe ndi makulidwe osiyanasiyana.
