KUFA KUPOSA NJIRA

Kodi kufa casting ndi chiyani?

Die casting ndi njira yoponyera zitsulo, yomwe imadziwika ndi kukakamiza kwambiri chitsulo chosungunula pogwiritsa ntchito mphuno ya nkhungu.Nthawi zambiri nkhungu zimapangidwa ndi aloyi amphamvu kwambiri, ndipo izi zimakhala zofanana ndi jekeseni.Zambiri zomwe zimafa zimakhala zopanda chitsulo, monga zinki, mkuwa, aluminiyamu, magnesium, lead, tin, ndi alloys a lead-tin ndi ma alloys awo.Malinga ndi mtundu wa kufa kuponyera, muyenera ntchito ozizira chipinda kufa kuponyera makina kapena otentha chipinda kufa kuponyera makina.

Mtengo wa zida zoponyera ndi nkhungu ndizokwera kwambiri, chifukwa chake njira yopangira kufa nthawi zambiri imagwiritsidwa ntchito popanga zinthu zambiri.Kupanga zitsulo zotayira kufa ndikosavuta, zomwe zimangofunika masitepe anayi okha, ndipo mtengo wake ndi wotsika kwambiri.Kufa kuponyera makamaka oyenera kupanga chiwerengero chachikulu cha castings ang'onoang'ono ndi sing'anga-kakulidwe, kotero kufa kuponyera ndi ambiri ankagwiritsa ntchito njira kuponyera.Poyerekeza ndi matekinoloje ena oponya, malo oponyera kufa ndi osalala ndipo ali ndi mawonekedwe apamwamba kwambiri.

Kutengera njira yachikhalidwe yoponya kufa, njira zingapo zowongolera zabadwa, kuphatikiza njira yopanda porous kufa-casting yomwe imachepetsa kuponyera ndikuchotsa porosity.Amagwiritsidwa ntchito kwambiri pokonza nthaka, yomwe imatha kuchepetsa zinyalala ndikuwonjezera zokolola za jekeseni mwachindunji.Palinso njira zatsopano zoponyera kufa monga ukadaulo wa precision die-casting ndi semi-solid die-casting.

Za nkhungu

Zowonongeka zazikulu zomwe zingachitike mu njira yoponyera imfa zimaphatikizapo kuvala ndi kukokoloka.Zowonongeka zina zimaphatikizapo kung'amba kwa kutentha ndi kutopa kwamafuta.Pamene nkhungu pamwamba ili ndi zolakwika chifukwa cha kusintha kwakukulu kwa kutentha, ming'alu ya kutentha idzachitika.Pambuyo pakugwiritsa ntchito kwambiri, zolakwika zomwe zili pamwamba pa nkhungu zimayambitsa kutopa kwamafuta.

Za zitsulo zakufa

Zitsulo zomwe zimagwiritsidwa ntchito poponya kufa makamaka zimaphatikizapo zinki, mkuwa, aluminiyamu, magnesium, lead, tin, ndi alloys a lead-tin.Ngakhale chitsulo chakufa ndi chosowa, chimakhalanso chotheka.Zitsulo zapadera zoponyera kufa zikuphatikiza ZAMAK, aluminium-zinc alloy, ndi miyezo ya American Aluminium Association: AA380, AA384, AA386, AA390, ndi AZ91D magnesium.Makhalidwe azitsulo zosiyanasiyana panthawi yakufa ndi awa:

Zinc: Chitsulo chomwe ndi chosavuta kuponya.Kupanga tizigawo ting'onoting'ono ndikotsika mtengo, ndikosavuta kuvala, kumakhala ndi mphamvu zopondereza kwambiri, pulasitiki yayikulu, komanso moyo wautali.

Aluminiyamu: Kulemera kopepuka, kukhazikika kwapamwamba kwambiri popanga zopangira zovuta komanso zoonda kwambiri, kukana kwa dzimbiri, zida zabwino zamakina, matenthedwe apamwamba ndi magetsi, komanso mphamvu yayikulu pakutentha kwambiri.

Magnesium: Ndiosavuta kupanga makina, imakhala ndi mphamvu zolemera kwambiri, ndipo ndiyopepuka kwambiri pakati pa zitsulo zomwe zimagwiritsidwa ntchito kwambiri.

Mkuwa: Kulimba kwambiri, kukana dzimbiri kolimba, makina abwino kwambiri azitsulo zomwe zimagwiritsidwa ntchito kwambiri, kukana kuvala, komanso mphamvu pafupi ndi chitsulo.

Kutsogola ndi malata: kachulukidwe kwambiri, kulondola kwapamwamba kwambiri, kumatha kugwiritsidwa ntchito ngati zida zapadera zotsutsana ndi dzimbiri.Poganizira zaumoyo wa anthu, aloyiyi sangathe kugwiritsidwa ntchito ngati zida zopangira chakudya ndi zosungirako.Aloyi ya lead, tini ndi antimony (nthawi zina imakhala ndi mkuwa pang'ono) ingagwiritsidwe ntchito kupanga zolemba zamanja ndi bronzing mu kusindikiza kwa letterpress.

Kuchuluka kwa ntchito:

Zigawo zoponyera zida sizilinso pamakampani opanga magalimoto ndi zida, ndipo zimakulitsidwa pang'onopang'ono kupita kumagulu ena amakampani, monga makina aulimi, zida zamakina, mafakitale amagetsi, makampani oteteza chitetezo, makompyuta, zida zamankhwala, mawotchi, makamera, ndi tsiku lililonse. hardware, etc. Makampani, makamaka: mbali za galimoto, zipangizo za mipando, zipangizo za bafa (bafa), mbali zounikira, zoseweretsa, zometa, zomangira zomangira, zida zamagetsi ndi zamagetsi, zomangira lamba, mawotchi, zingwe zachitsulo, maloko, zipi, ndi zina zotero.

Aubwino:

1. Ubwino wa mankhwala

Kulondola kwapang'onopang'ono kwa ma castings ndikwambiri, nthawi zambiri kumakhala kofanana ndi 6-7, mpaka 4;kutsirizitsa pamwamba ndi kwabwino, nthawi zambiri kumakhala kofanana ndi 5-8;mphamvu ndi kuuma ndizokwera, ndipo mphamvu nthawi zambiri imakhala 25 ~ 30% kuposa kuponya mchenga, koma imakulitsidwa Mlingo umachepetsedwa pafupifupi 70%;kukula kwake ndi kokhazikika, ndipo kusinthasintha kuli bwino;ikhoza kufa-kuponyedwa ndi mipanda yopyapyala yokhala ndi mipanda yovuta.

2. Kupanga kwakukulu

3. Zabwino kwambiri zachuma

Chifukwa cha kukula kwake kwakufa, pamwamba pake ndi yosalala komanso yoyera.Kawirikawiri, amagwiritsidwa ntchito mwachindunji popanda makina opangira mawotchi, kapena voliyumu yowonongeka ndi yaying'ono, kotero sikuti imangowonjezera kuchuluka kwa ntchito yachitsulo, komanso imachepetsanso zida zambiri zogwirira ntchito ndi maola a munthu;mtengo wa castings ndi wosavuta;imatha kuphatikizidwa ndi zida zina zachitsulo kapena zopanda zitsulo.Imapulumutsa osati msonkhano munthu-maola komanso zitsulo.

Zoyipa:

Mtengo wa zida zoponyera ndi nkhungu ndizokwera kwambiri, motero njira yopangira kufa nthawi zambiri imagwiritsidwa ntchito popanga zinthu zambiri m'magulu, ndipo kupanga batch yaying'ono sikungawononge ndalama zambiri.

QY Precisionali ndi chidziwitso chonse mu Die Casting Process, ndipo amapereka mayankho osiyanasiyana kuti akwaniritse zosowa zanu.Mutha kusankha yoyenera pazogulitsa zanu zomaliza ndi msika.Takulandilani tumizani zojambula zanu za 2D/3D kuti mupeze mawu aulere.
