Mfundo posankha malo a chipata cha zisankho zoponyera magalimoto

Pamapangidwe a zisankho zamagalimoto, kusankha kwa chipata nthawi zambiri kumakhala kocheperako ndi zinthu monga mtundu wa aloyi, kapangidwe kake ndi mawonekedwe, kusintha kwa makulidwe a khoma, kusinthika kwa shrinkage, mtundu wamakina (yopingasa kapena ofukula), komanso zofunikira zogwiritsira ntchito.Chifukwa chake, pazigawo zoponya kufa, malo abwino a pachipata ndi osowa.Pakati pazifukwa zomwe ziyenera kuganiziridwa, malo a pakhomo angatsimikizidwe kokha mwa kukwaniritsa zofunikira zazikulu, makamaka pa zosowa zina zapadera.

Malo omwe ali pachipata cha nkhungu zoponyera kufa pamagalimoto amayamba kuchepetsedwa ndi mawonekedwe a magawo oponyedwa, ndikuganiziranso zinthu zina.

(1) Malo a pachipata ayenera kutengedwa pamalo omwe ndondomeko yazitsulo zodzaza madzi Z ndi yochepa ndipo mtunda wopita kumadera osiyanasiyana a nkhungu ndi pafupi kwambiri kuti muchepetse kuzunzika kwa njira yodzaza ndikupewa kupotoza kwambiri.Choncho, tikulimbikitsidwa kugwiritsa ntchito chipata chapakati momwe mungathere.

(2) Kuyika pachipata cha chiwombankhanga choponyera magalimoto pagawo la Z-thick of the die-casting khoma kumathandizira kuti pakhale kuthamanga kwa Z-final.Panthawi imodzimodziyo, chipatacho chili m'dera la khoma lakuda, ndikusiya malo owonjezera kukula kwa chipata chamkati.

(3) Malo a chipata akuyenera kuwonetsetsa kuti kugawidwa kwa gawo la kutentha kwa patsekeke kumakwaniritsa zofunikira, ndikuyesera kukwaniritsa zomwe zimadzaza madzi achitsulo mpaka kumapeto kwa Z.

(4) Chipata cha galimoto kufa-kuponyera nkhungu amatengedwa pamalo pamene zitsulo zamadzimadzi zimalowa mu nkhungu popanda vortices ndi utsi ndi wosalala, zomwe zimathandiza kuthetsa mpweya mu nkhungu patsekeke.Pochita kupanga, ndizovuta kwambiri kuthetsa mpweya wonse, koma ndi kulingalira kwapangidwe kuyesa kuthetsa mpweya wochuluka momwe mungathere malinga ndi mawonekedwe a kuponyera.Nkhani yotulutsa mpweya iyenera kuyang'aniridwa mwapadera ku castings ndi zofunikira za mpweya.

(5) Kwa ma castings opangidwa ndi bokosi, malo olowera pachipata atha kuyikidwa mkati mwazomwe zimapangidwira.Ngati chipata chimodzi chadzaza bwino, palibe chifukwa chogwiritsira ntchito zipata zambiri.

(6) Malo a chipata cha nkhungu yoponyera galimotoyo ayenera kukhala pafupi kwambiri ndi malo omwe chitsulo sichimakhudza mwachindunji pachimake, ndipo chiyenera kupewedwa kuti chiwononge chitsulo (kapena khoma). ).Chifukwa atatha kugunda pachimake, mphamvu ya kinetic ya chitsulo chosungunula imatayika mwamphamvu, ndipo zimakhalanso zosavuta kupanga madontho obalalika omwe amasakanikirana ndi mpweya, zomwe zimapangitsa kuti pakhale kuwonongeka kwa kuponyera.Pambuyo pakuwonongeka kwapakati, kumapanga nkhungu kumamatira, ndipo pazovuta kwambiri, malo owonongeka amapanga kukhumudwa, komwe kumakhudza kugwetsa kwa kuponyera.

(7) Malo a chipata ayenera kukhazikitsidwa pamalo omwe n'zosavuta kuchotsa kapena kuwombera chipata pambuyo popanga.

(8) Pazigawo zakufa zomwe zimafuna kulimba kwa mpweya kapena sizimalola kukhalapo kwa pores, wothamanga wamkati ayenera kukhazikitsidwa pamalo omwe zitsulo zamadzimadzi Z zimatha kusunga kupanikizika nthawi zonse.
