Kufa kuponyaamagwiritsidwa ntchito pafupipafupinjira yopangira jekeseni wachitsulozomwe zimaphatikizapo kuthira zinthu zotayidwa mu nkhungu, kugwiritsa ntchito kukakamiza kuti zinthu ziwonongeke panthawi yozizira komanso yotentha, ndiyeno kuchotsa zinthu zotayidwa mu nkhungu kuti apange mawonekedwe omwe akufuna.
Kuti akwaniritse zofuna za kupanga anthu ambiri, njira yoponyera kufa ndiyothandiza kuchepetsa kugwiritsa ntchito zinthu, imatha kuchepetsa kuwongolera, ndipo kuumba kwake ndi magwiridwe antchito zimakhala zokhazikika.
Kupanga kwa Die casting kumadalira kapangidwe ka nkhungu yoponya kufa, yomwe imakhudza mwachindunji njira yoponyera kufa ndi zotsatira zake. Kukonzekera koyenera kwa nkhungu yofa kungapereke mankhwala ndi ntchito yabwino, pamene mapangidwe olakwika angapangitse chisokonezo cha ndondomeko ndi zowonongeka, kukweza mtengo wa kupanga ndi kukonzanso. Pofuna kuonetsetsa kuti kufa kuponyera nkhungu ali okwanira kuvala kukana, asidi ndi alkali kukana, kukana dzimbiri, komanso kusindikiza kwambiri, bata matenthedwe, ndi zina zabwino kufa kuponyera ntchito, kufa kuponyera nkhungu kapangidwe ayenera kuganizira zipangizo ntchito, njira kutentha mankhwala, kapangidwe nkhungu, kukula nkhungu, magawo nkhungu, kuyeretsa pamwamba, ndi zina.
Kufa kuponyera nkhungu kapangidweAyenera kugwiritsa ntchito makina oyerekeza amitundumitundu amitundumitundu komanso umisiri wocheperako kuti athe kukulitsa kapangidwe kake pogwiritsa ntchito njira yatsopano, kuzindikira kukula kwazinthu mwachangu, kufupikitsa kayendedwe kachitukuko, komanso kukulitsa mtundu wazinthu.
Ngakhale mapangidwe olondola amapereka maziko olimba opangira magawo ovuta, palinso zoopsa zomwe zimakhudzidwa, chifukwa chake kukhazikitsa nkhungu yakufa kuyenera kusinthidwa mosalekeza malinga ndi malo enieni ogwirira ntchito.
Mawonekedwe ndi kuchuluka kwa ntchito zaukadaulo wa die casting
1.die casting teknoloji makhalidwe
Makhalidwe awiri oyambira amadzimadzi kapena semi-amadzimadzi zitsulo zomangira zitsulo zomwe zimagwiritsidwa ntchito poponya kufa, komanso masiyanidwe awiri ofunikira pakati paukadaulo woponya kufa ndi njira zina zoponyera, ndi kuthamanga kwambiri komanso kuthamanga kwambiri.
2. Zomwe zimagwiritsidwa ntchito paukadaulo wa kufa
Imodzi mwa njira zotsogola kwambiri zopangira zitsulo ndikuponya kufa, ndipo zimagwira ntchito bwino kupanga zida zopanda kupukuta pang'ono.
Pakadali pano, ma alloys omwe amagwiritsidwa ntchito popanga kufa akukulirakulira pang'onopang'ono ndikuyika zida zina osati zinki, aluminiyamu, magnesium, ndi ma aloyi amkuwa.
Zojambula zakufa zimapangidwa kuchokera kuzitsulo zachitsulo monga chitsulo ndi zitsulo zotayidwa.
Kufa akuponya nkhungu zakuthupi
Malingana ndi mtundu wa zitsulo zomwe zimayenera kukonzedwa, kukula kwa katundu, kugwiritsa ntchito kutentha ndi kupanga liwiro, zofunikira zosiyanasiyana zimayikidwa patsogolo kuti zisankhe mitundu yosiyanasiyana ya ntchito yotentha kufa zitsulo. The ω (c) ya otentha ntchito die zitsulo zambiri 0,3 ~ 0.6%, pamene zili mpweya wochuluka, kulimba ndi plasticity wa chitsulo kuchepa, ndi madutsidwe matenthedwe osauka; Pamene carbon zili otsika kwambiri, kuuma ndi kuvala kukana sangathe kukwaniritsa zofunika.
Hot ntchito kufa zitsulo zambiri kuwonjezera Cr, Mn, Ni, Si ndi zinthu zina kulimbikitsa masanjidwewo ferritic, kusintha hardnessability mphamvu ndi toughness zitsulo, Ni akhoza kusintha matenthedwe kukana kutopa, kuti yeretsani njere patsogolo mphamvu ndi kuuma, tempering bata, kupewa tempering brittleness, komanso kuwonjezera Ni, Mo, V ndi zinthu zina. Komanso, Ni, Mo, V ndi zinthu zina precipitated mu mawonekedwe a carbide pa tempering kutulutsa yachiwiri kuumitsa, kuti ntchito yotentha kufa zitsulo akhoza kukhalabe ndi mphamvu mkulu pa kutentha apamwamba.
Aluminiyamu nkhungu
Ndi kachulukidwe kakang'ono komanso mphamvu yayikulu, aloyi ya aluminiyamu ikukula kwambiri. Pambuyo pake mankhwala ake atakonzedwa bwino,kuponyedwa kwa aluminiyumu, hot extrusion, ndi kukalamba kochita kupanga zidagwiritsidwa ntchito kuti zitheke. Zopangidwa kuchokera ku aluminiyamu alloy die-casting zimagwiritsidwa ntchito makamaka pamagetsi, magalimoto, zida zapakhomo, zamagalimoto, ndi mafakitale ena olumikizirana. Ndege zazikulu, zombo, ndi mafakitale ena omwe ali ndi luso lapamwamba laukadaulo amagwiritsanso ntchito zinthu zina za aluminiyamu zapamwamba kwambiri zogwira ntchito kwambiri, zolondola kwambiri, komanso zolimba kwambiri, ngakhale kuti ntchito zake zoyambirira zikadali pamakina ena.
The zotayidwa aloyi kufa kuponyera njira ndi apamwamba kuposa ochiritsira zotayidwa aloyi kupanga matekinoloje m'njira zotsatirazi: lalikulu zosiyanasiyana kufa kuponyera; Pang'onopang'ono kukhazikika bwino ndi kulondola kwapamwamba kwambiri; Mphamvu zoponya, kuuma kwapamwamba kwambiri, kutsika kwamphamvu, zokolola zambiri, kugwiritsa ntchito zitsulo zambiri, ndi zina zotero.
Chitukuko cha kamangidwe ka zida za kufa casting
Mapangidwe a nkhungu akuyenera kuganizira zofuna za wogwiritsa ntchito kuti atumize mwachangu, molondola kwambiri, komanso kupanga nkhungu yotsika mtengo.
Zotsatira za kukula sizingapeweke:
1.Mapangidwe a Mold kuchokera pagawo lamalingaliro kupita ku chitsogozo cha kusanthula kwamalingaliro ndi kapangidwe kothandizidwa ndi makompyuta.
Bizinesi ya nkhungu imagwiritsa ntchito kwambiri ukadaulo wa CAD/CAM/CAE, womwe umawonjezera kuchuluka kwa nkhungu ndikupanga kupanga nkhungu kukhala koyenera komanso kwasayansi.
2.Precision, kupanga nkhungu yofulumira komanso kupanga, komanso kadulidwe kakang'ono kachitukuko.
3.Msika wa CAD/CAE/CAM ukupita ku kuphatikizika, mbali zitatu, nzeru, ndi maukonde.
4. Chikombolechi chimasanduka kulondola, zovuta, ndi zazikulu; Tekinoloje yochokera ku Knowledge-based Engineering (KBE). 5.kuwonjezera mlingo wa standardization wa nkhungu ndi mlingo wa nkhungu standardization magwiritsidwe.
Ningbo Jiehuang kufa akuponya nkhungu wopanga High kufa-casting-mold, Ningbo jiehuang kufa kuponyera kampani ikukula mu malangizo anzeru. Kafukufuku ndi chitukuko cha zida zatsopano zoponyera kufa kuti zikwaniritse zosowa za kupita patsogolo kwaukadaulo wamafakitale. Kafukufuku ndi chitukuko cha zida zatsopano zoponyera kufa, kupititsa patsogolo kuchuluka kwa makina, kupanga ukadaulo watsopano wozindikira. Pangani ukadaulo watsopano woponya kufa, sinthani ndikuwonjezera njira yoponya kufa, onjezerani moyo wakufa, kuchepetsa ndalama zopangira, kuthetsa vuto la kuponya kwachitsulo chakuda.
