KunyumbaAluminium Extrusion
Zomwe zimadziwikanso kuti ma profiles a aluminiyamu, ndiatali, amphamvu akalumikizidwe opangidwa kudzera munjira ya aluminiyamu extrusion. Njirayi imaphatikizapo kukankhira billet yotenthedwa ya aluminiyamu mukufa, komwe kumapanga mbiri zosiyanasiyana.
Mbiriyi imagwiritsidwa ntchito kwambiri m'mafakitale ambiri chifukwa cha kusinthasintha, kukhazikika komanso kutsika mtengo.
Zimayamba ndi kutentha billet ya aluminiyamu kutentha kwapadera. Izi zimapangitsa chitsulo kukhala chosavuta komanso choyenera kutulutsa. Chopanda chotenthetseracho chimakankhidwa kudzera mukufa kopangidwa mwapadera pogwiritsa ntchito makina osindikizira a hydraulic kapena nkhonya. Chikombolechi chimapatsa aluminiyamu extrusion mawonekedwe omwe amafunidwa ndi mawonekedwe apakati. Pambuyo pa extrusion, mbiriyo imadulidwa mpaka kutalika kofunikira ndipo ikhoza kukumana ndi njira zowonjezera monga chithandizo chapamwamba kapena makina.
Choyamba, ali ndi chiŵerengero chabwino kwambiri cha mphamvu ndi kulemera, zomwe zimawapangitsa kukhala opepuka koma amphamvu. Izi zimawapangitsa kukhala abwino kwa mapulogalamu omwe kuchepetsa kulemera ndikofunikira, monga m'mafakitale amagalimoto ndi ndege. Chachiwiri, njira ya extrusion imatha kupanga mawonekedwe ovuta komanso mapangidwe ovuta. Kusinthasintha kumeneku kumathandizira kupanga ma profaili osinthidwa omwe amakwaniritsa zofunikira zenizeni. Chachitatu, mbiri ya aluminiyamu imakhala ndi kukana kwa dzimbiri, zomwe zimawalola kupirira madera ovuta popanda kusokoneza kukhulupirika kwawo. Kuphatikiza apo, aluminiyamu imatha kubwezeredwanso kwambiri, ndikupangitsa kuti ikhale chisankho chokonda zachilengedwe.
Pantchito yomanga, mbiriyi imagwiritsidwa ntchito pazithunzi zazenera, makoma a nsalu ndi zigawo zamapangidwe. Kukana kwawo kwa dzimbiri, kulemera kwake komanso kukongola kumawapangitsa kukhala abwino pantchito yomanga. M'makampani oyendetsa magalimoto, mbiri ya aluminiyamu imagwiritsidwa ntchito pazigawo za chassis, zosinthira kutentha ndi mapanelo amthupi. Mphamvu zawo, kulemera kwake komanso kusinthasintha kwamafuta zimawapangitsa kukhala abwino kuwongolera bwino mafuta komanso kuchepetsa kutulutsa mpweya. Kuphatikiza apo, makampani opanga magetsi amagwiritsa ntchito ma aluminium extrusions potengera kutentha, kuyatsa kwa LED, ndi mpanda wamagetsi chifukwa cha matenthedwe ake abwino kwambiri. Makampani ena monga mayendedwe, makina ndi katundu wogula amapindulanso pogwiritsa ntchito mbiri ya aluminiyamu.
Mbiri za aluminiyamu zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kusinthasintha, kulimba, komanso kupepuka. Atha kupezeka muzomanga, zoyendera, zamagetsi, ndi ntchito zina zambiri. Ngakhale aluminiyumu yokha imakhala ndi kukana kwa dzimbiri komanso malo osalala, chithandizo chapamwamba chimagwiritsidwa ntchito kuti chiwongolere mawonekedwe ake ndi mawonekedwe ake. Njira zina zochizira zamtundu wa aluminiyamu ndizo:
Kumaliza kwa Mill: chomwe ndi aluminiyamu aloyi choyambirira mtundu mwachindunji extruder ku extruder. Zomwe zikutanthauza kuti sayenera kugwiritsa ntchito mankhwala ena padziko lapansi.
Anodizing: Anodizing ndi njira ya electrochemical yomwe imapanga chitsulo chosanjikiza cha oxide pamwamba pa aluminiyamu, zomwe zimapangitsa kuti zisawonongeke komanso kuuma. Imalolezanso zosankha zamitundu ndikuwongolera kukongola kwa aluminiyumu.
Poda zokutira: Kupaka ufa kumaphatikizapo kupaka utoto wouma pamwamba pa aluminiyamu motengera magetsi. Ma profiles ophimbidwa amachiritsidwa mu uvuni, zomwe zimapangitsa kuti zikhale zolimba komanso zowoneka bwino. Kupaka utoto kumapereka chitetezo chabwino kwambiri ku nyengo, kuwala kwa UV, ndi abrasion.
Kupukutira: Kupukuta ndi njira yamakina yomwe imapangitsa kuti pakhale mawonekedwe osalala komanso owala pazithunzi za aluminiyamu. Imakulitsa mawonekedwe a mbiriyo ndikuwapatsa mawonekedwe ngati galasi.
Kutsuka: Brushing ndi njira yochizira pamwamba yomwe imapanga mizere yozungulira kapena yozungulira ya maburashi pambiri za aluminiyamu. Itha kupereka mawonekedwe amakono komanso otsogola ku mbiriyo ndipo imagwiritsidwa ntchito nthawi zambiri pazomangamanga.
Electrophoresis: Electrophoresis ndi njira yokutira yamagetsi yamagetsi yomwe imatsimikizira kuti yunifolomu ndi zosagwira dzimbiri kumapeto kwa aluminiyumu. Zimapereka kumamatira kwabwino komanso kumapangitsa kuti mbiriyo ikhale yolimba komanso kukana nyengo.
Mbiri ya aluminiyamu imatha kupangidwa pogwiritsa ntchito mitundu yosiyanasiyana ya aluminiyamu aloyi, iliyonse ili ndi mawonekedwe ake. Zina zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu alloy ma profaili ndi awa:
6063: Ichi ndiye kalasi yodziwika bwino ya aluminiyamu yomwe imagwiritsidwa ntchito popanga mbiri. Amapereka extrudability yabwino, kukana dzimbiri, komanso kumaliza kwapamwamba. Amagwiritsidwa ntchito kwambiri pomanga, monga mafelemu awindo, mafelemu a zitseko, ndi makoma a nsalu.
6061: Ndi aloyi yamphamvu kwambiri yokhala ndi makina abwino kwambiri komanso kukana kwa dzimbiri. Imapeza ntchito m'magawo am'madzi, magawo am'mapangidwe, ndi mafakitale amayendedwe.
6082: Wodziwika chifukwa cha mphamvu zake zapadera komanso kukana dzimbiri, aloyi ya 6082 imagwiritsidwa ntchito kwambiri pamapangidwe ndi zoyendera, monga milatho, ma trusses, ndi zida zamagalimoto.
6005: Aloyi izi ali ndi extrudability zabwino ndi mphamvu. Nthawi zambiri amasankhidwa kuti akhale ndi mbiri yomwe imafunikira makina ozama, monga zoyatsira kutentha ndi zotchingira zamagetsi.
7005: Ndi aloyi yamphamvu kwambiri yokhala ndi kulimba kwabwino. Ndizoyenera kugwiritsa ntchito zomwe zimafunikira kusamalidwa kwakukulu, monga mafelemu apanjinga, zida zamagalimoto, ndi zida zamasewera.
Izi ndi zitsanzo zochepa chabe za magulu ambiri a aluminiyamu aloyi omwe amapezeka kuti apange mbiri. Kusankhidwa kwa giredi ya alloy kumatengera zomwe mukufuna kugwiritsa ntchito, kuphatikiza mphamvu, kukana kwa dzimbiri, extrudability, ndi kumaliza pamwamba.
