Kuponyedwa kwa aluminiyamu ndi njira yopangira zida zololera komanso zapamwamba kwambiri pothira aluminiyumu yosungunuka mukufa, nkhungu, kapena mawonekedwe opangidwa bwino kwambiri. Ndi njira yabwino yopangira zigawo zovuta, zovuta, zatsatanetsatane zomwe zimagwirizana ndendende ndi zomwe zidapangidwa poyamba.
Njira Yopangira Aluminium
1.Permanent Mold Casting
Zambiri zomwe zimawonongerapo aluminiyumu yokhazikika ndikuyika nkhungu ndi kukonza ndi kupanga nkhungu, yomwe nthawi zambiri imapangidwa kuchokera kuchitsulo chotuwa kapena chitsulo. Chikombolecho chimapangidwa mu mawonekedwe a geometric a gawo lopangidwa ndi ndondomeko ndi mawonekedwe a gawo lomwe lagawidwa m'magawo awiri. Mu jekeseni, ma halves a nkhungu amatsekedwa mwamphamvu kotero kuti palibe mpweya kapena zonyansa zomwe zilipo. Chikombolecho chimatenthedwa chisanatsanulidwe aluminium yosungunuka, yomwe imatha kunyamulidwa, kuthiridwa, kapena kubayidwa.
Pomaliza ntchitoyi, nkhungu imaloledwa kuziziritsa kuti gawo la aluminiyamu likhale lolimba. Ukazizira, gawolo limachotsedwa mwachangu mu nkhungu kuti zisapangike zolakwika.
Ngakhale kuti njirayi ingawoneke ngati yophweka bwanji, ndi njira yopangidwa mwasayansi komanso mwaukadaulo popanga zigawo zazikulu.
2.Kuponya Mchenga
Kuponyera mchenga kumaphatikizapo kulongedza mchenga mozungulira ndondomeko yogwiritsidwanso ntchito yomwe ili ndi mawonekedwe, tsatanetsatane, ndi makonzedwe a chinthu chomaliza. Zomwe zili m'gululi ndi zokwera zomwe zimalola kuti zitsulo zosungunuka zitsanulidwe mu nkhungu komanso kuti aluminiyamu yotentha idyetse kuponyera panthawi yolimba kuti muteteze shrinkage porosity.
Kuphatikizidwa mu chitsanzocho ndi sprue yomwe imalola chitsulo chosungunuka kuti chilowetsedwe mu nkhungu. Miyeso ya chitsanzo ndi yokulirapo pang'ono kuposa mankhwala kuti awerengere kuchepa panthawi yozizira. Mchenga uli ndi kulemera ndi mphamvu kuti ukhalebe mawonekedwe a chitsanzocho ndipo umalimbana ndi kugwirizana ndi chitsulo chosungunuka.
4. Vacuum Die Casting Vacuum die casting imagwiritsa ntchito belu lopanda mpweya lomwe lili ndi potsegulira pansi komanso chotulutsira vacuum pamwamba. Njirayi imayamba ndi kumiza sprue pansi pa aluminiyumu yosungunuka. Vacuum imapangidwa mu cholandirira ndikupanga kusiyana kwapakati pakati pa phazi lakufa ndi aluminiyumu yosungunuka mu crucible.
Kusiyana kwa mphamvuyi kumapangitsa kuti aluminiyumu yosungunukayo aziyenda pamwamba pa sprue kulowa m'mphako, pomwe aluminiyumu yosungunukayo imakhazikika. Imfa imachotsedwa kwa wolandila, kutsegulidwa, ndipo gawolo limatulutsidwa.
Kuwongolera vacuum ndi kusiyana kwapakatikati pakati pa difa ndi aluminiyamu yosungunuka kumapangitsa kuti zitheke kuwongolera kuchuluka kwa kudzaza komwe kumafunikira ndi kapangidwe kagawo ndi zofunikira za gating. Kuwongolera kuchuluka kwa kudzaza kumakulitsa luso lozindikira kumveka kwa gawo lomalizidwa.
Kumizidwa kwa sprue pansi pa aluminiyamu yosungunuka kumatsimikizira kuti aluminiyumu yosungunukayo idzakhala alloy yoyera yopanda ma oxides ndi doss. Zigawo zake ndi zaukhondo komanso zomveka popanda zida zakunja.
5.Investment Casting
Kuponyera ndalama, komwe kumadziwikanso kuti kutayika kwa sera, kumayamba ndi kubayidwa sera mukufa kuti apange chitsanzo cha mankhwala omalizidwa. Mapangidwe a phula amamangiriridwa ku sprue kuti apange mtengo wa ike kasinthidwe. Mtengowo umaviikidwa mu slurry kangapo, zomwe zimapanga chipolopolo cholimba cha ceramic kuzungulira mawonekedwe a sera.
Ceramic ikakhazikika ndikuwumitsidwa, imatenthedwa mu autoclave kuti amalize kutentha kwa dewax. Kuti akwaniritse kutentha kofunikira kwa chipolopolocho, amatenthedwa asanadzazidwe ndi aluminiyamu yosungunuka, yomwe imatsanuliridwa mu sprue ndikudutsa mndandanda wa othamanga ndi zipata kulowa mu nkhungu. Ziwalo zikawuma, choumbacho chimachotsedwa ndikusiya mtengo wolumikizidwa kuti udulidwe mumtengo.
6.Kutaya Chithovu Chotayika
Njira yotayira thovu yotayika ndi mtundu wina woponya ndalama pomwe sera imasinthidwa ndi thovu la polystyrene. Chitsanzocho chimapangidwa kuchokera ku polystyrene mumsonkhano wamagulu monga wothamanga ndi sprues of casting casting. Mikanda ya polystyrene imabayidwa mu nkhungu zotenthetsera za aluminiyamu pamphamvu yotsika ndikuwonjezera nthunzi kuti ikulitse polystyrene kudzaza mabowo.
Chitsanzocho chimayikidwa mumchenga wowuma wodzaza kwambiri womwe umagwedezeka kuti uchotse voids kapena matumba a mpweya. Pamene aluminiyumu yosungunuka imatsanuliridwa mu nkhungu yamchenga, chithovucho chimatenthedwa, ndipo kuponyedwa kumapangidwa.
Kugwiritsa Ntchito Wamba kwa Casting Aluminium
Chifukwa cha mphamvu zake zakuthupi komanso zamankhwala, mafakitale akuluakulu ambiri amagwiritsa ntchito aluminiyamu yotayirira. Nawa njira zingapo zomwe zimagwiritsidwa ntchito pazambiri.
1. Makampani azachipatala
Opanga mbali zachipatala amadalira zitsulo za aluminiyamu chifukwa cha mphamvu zawo ndi zopepuka popanga ma prosthetics, ma trays opangira opaleshoni, ndi zina zotero. Kupatula apo, ndondomekoyi ndi yoyenera kupanga mawonekedwe ovuta komanso olondola omwe makampaniwa amadziwika. Komanso, aluminiyamu ndi chinthu choyenera chifukwa cha kukana kwa dzimbiri popeza zida zambiri zamankhwala zimakumana ndi madzi amthupi.
2. Makampani opanga magalimoto
Opanga zida zamagalimoto amadalira zotayira za aluminiyamu kuti zikhale zopepuka popanda kukhala ndi mphamvu komanso kulimba. Zotsatira zake, zathandiza kuti mafuta aziyenda bwino. Kuphatikiza apo, kupanga zida zamagalimoto zokhala ndi mawonekedwe ovuta ndi njira yopangira aluminiyamu ndikosavuta. Zida za aluminiyamu ndizoyenera kupanga mbali monga mabuleki ndi mawilo.
3. Makampani Ophikira
Aluminiyamu ya Cast ndiyothandiza pantchito zophikira chifukwa cha kulimba kwake, kukana dzimbiri, kupepuka, komanso kuwongolera kwambiri kutentha. Kupatula apo, zinthuzo ndizoyenera kupanga zophikira chifukwa cha kutentha kwambiri, mwachitsanzo, zimatha kutentha ndikuzizira mwachangu.
4. Makampani Oyendetsa Ndege
Magawo a aluminiyamu ndi abwino kwa makampani opanga ndege chifukwa chopepuka komanso mphamvu. Kulemera kwake kumapangitsa ndege kugwiritsira ntchito mafuta ochepa kuti ikhale yolemera kwambiri.
