A: Kuponyera kupanikizika ndi njira yoponyera yomwe madzi osungunuka amathiridwa m'chipinda choponderezedwa, chibowo cha nkhungu chachitsulo chimadzazidwa ndi liwiro lalikulu, ndipo madzi a alloy amalimbikitsidwa kuti apange kuponyera.Mbali zazikulu za kuponyera kufa zomwe zimasiyanitsa ndi njira zina zoponyera ndizothamanga komanso kuthamanga kwambiri.

Makina oponyera kufa, ma aloyi oponyera kufa ndi nkhungu zoponya kufa ndi zinthu zitatu zazikuluzikulu zopanga zida zakufa ndipo ndizofunikira kwambiri.Zomwe zimatchedwa kufa-casting process ndi kuphatikiza kwachilengedwe kwa zinthu zitatuzi, zomwe zimapangitsa kuti pakhale kukhazikika, momveka bwino komanso kothandiza kupanga ma castings ndi mawonekedwe, khalidwe labwino lamkati, ndi kukula kwa zojambula kapena zofunikira za mgwirizano.

A:

(1) Ikhoza kukwaniritsa zofunikira za machitidwe a imfa.

(2) Malo osungunuka ndi otsika, kutentha kwa crystallization ndi kochepa, madzi otentha pa kutentha pamwamba pa malo osungunuka ndi abwino, ndipo kuchuluka kwa shrinkage pambuyo pa kulimbitsa kumakhala kochepa.

(3) Lili ndi mphamvu zokwanira ndi pulasitiki pa kutentha kwakukulu, ndipo zimakhala ndi brittleness yochepa yotentha.

(4) Zinthu zabwino zakuthupi ndi zamankhwala monga kukana kuvala, madulidwe amagetsi, matenthedwe amafuta, komanso kukana dzimbiri.

A: Nthawi zambiri, ntchito yeniyeni mumakampani opanga ma kufa si 100% aluminiyamu yoyera, koma yokhala ndi aluminiyumu yoyambira 95% mpaka 98.5% (aluminiyamu yakufa-cast yokhala ndi ntchito yabwino ya anodizing), ndipo aluminiyamu yoyera iyenera kukhala kuposa 99.5% zotayidwa (Monga koyera zotayidwa rotor kufa kuponyera).Chifukwa cha matenthedwe ake abwino amatenthedwe ndi anodizing katundu, aluminiyamu nthawi zambiri amagwiritsidwa ntchito m'malo otentha otentha ndi mankhwala pamwamba pomwe zofunika mtundu ndi mkulu.

Poyerekeza ndi ochiritsira zotayidwa aloyi die-casting (monga ADC12), chifukwa mkulu pakachitsulo zili, mlingo shrinkage ndi ochepa 4-5%;koma aluminiyamu kwenikweni alibe pakachitsulo, mlingo shrinkage ndi 5-6%, kotero ochiritsira zotayidwa aloyi kufa-kuponya alibe zotsatira anodizing.

A: Makina oponyera kufa amatha kugawidwa m'mitundu iwiri, makina oponyera achipinda chotentha ndi makina oponyera achipinda chozizira.Kusiyana kwagona pa kuchuluka kwa mphamvu zomwe zingapirire.Kuthamanga kwanthawi zonse kumachokera ku matani 400 mpaka 4,000.Hot chamber die casting ndi chitsulo chosungunuka, chamadzimadzi, chamadzimadzi mu dziwe lachitsulo lomwe limadzaza nkhunguyo mopanikizika.Cold die casting itha kugwiritsidwa ntchito ngati zitsulo zoponyera kufa zomwe sizingagwiritsidwe ntchito poponyera m'chipinda chotentha, kuphatikiza aluminium, magnesium, copper, ndi zinc alloys okhala ndi aluminiyumu yayikulu.Pochita izi, chitsulocho chiyenera kusungunuka choyamba mu crucible yosiyana.Chitsulo china chosungunuka chimasamutsidwa kuchipinda chojambulira chosatenthedwa kapena mphuno;kusiyana pakati pa chipinda chotentha ndi chipinda chozizira ndikuti ngati jekeseni wa makina oponyera akufa amamizidwa muzitsulo zachitsulo.

A: Hot chipinda kufa kuponyera makina: nthaka aloyi, magnesium aloyi, etc.

Cold chipinda kufa kuponyera makina: nthaka aloyi, magnesium aloyi, zotayidwa aloyi, aloyi yamkuwa, etc.

Oima kufa kuponyera makina: nthaka, zotayidwa, mkuwa, lead, malata;

A:

1. Kuchita bwino koponya

2. Kutsika kochepa (2.5 ~ 2.9 g / cm 3), mphamvu zambiri.

3. Chitsulo chachitsulo chokhala ndi kuthamanga kwambiri komanso kuthamanga kwachangu pa nthawi ya kufa

4, khalidwe la mankhwala ndi labwino, kukula kwake ndi kokhazikika, ndi kusinthana kwabwino;

5, kupanga bwino kwambiri, kuchuluka kwa nthawi yomwe nkhungu yoponya ufa imagwiritsidwa ntchito;

6, yoyenera pakupanga kwakukulu kwakukulu, kubweza zabwino zachuma.

A: Zomwe zimagwiritsidwa ntchito kwambiri pochiza zitsulo zotayidwa ndi aluminiyumu zowonongeka ndi: utoto wa electrophoretic, electroplating, jekeseni wamafuta, kuphulika kwa mchenga, kuphulika kwa kuwombera, anodizing, vanishi wophika, varnish yotentha kwambiri, anti- dzimbiri passivation ndi zina zotero.
