Aluminium Alloy Die Casting Production Process

Aluminium alloy kugadzira maitiro ari nyore, ari nyore kushanda, kushanda kwakanyanya, nyore kuona otomatiki kugadzirwa. Aluminium alloy die casting machine yesimbi yakanyungudutswa yakananga kubva mukamuri yekumanikidza kupinda mugomba, kushandiswa kwesimbi kushoma, tembiricha yekuchinja kwemhando idiki, kufa kukandira maitiro kwakagadzikana. Kufa uchikanda simbi mvura ine yakavharwa chiteshi mugomba, tsvina haisi nyore kutakura, kufa kukanda mhando yakanaka. Panguva imwecheteyo, nekuda kweiyo yakaderera chaiyo yekukanda kufa, iyo yekumanikidza chamber, punch, mvura spout, etc. Kunyudzwa kwenguva refu musimbi yakanyungudutswa, iri nyore kuita ngura, inokanganisa hupenyu hwesevhisi, nyore kuita ngura. Wedzera simbi yemukati mune alloy. Nokuti magnesium chiwanikwa uye zvimwe zvinopfuta yakaderera kunyunguduka pfungwa alloy kufa vachikandira, anogona kunamwa hari, kuburikidza inert gasi kudzivirira alloy mvura, kudzivirira oxidation yayo kana combustion. Parizvino, hot chamber die casting machine inonyanya kushandiswa kune zinc alloy uye imwe yakaderera melting point alloy casting die casting, asi inoshandiswawo kune diki aluminium uye magnesium alloy die casting.

Izvo zvakakosha zvimiro zvekukanda kufa zvinosanganisira ukobvu hwemadziro, kusimbiswa, makomba ekukanda, kukanda makona akatenderedzwa, kudhonza mold mutserendende, shinda, magiya, grooves, rivet musoro, zororo, mesh, zvinyorwa, logo, patani, yakamisikidzwa castings uye zvichingodaro. Kufa kukanda kwakaringana madziro ukobvu kunoenderana neiyo chaiyo chimiro chekukanda, alloy zvivakwa uye kufa kukanda maitiro uye zvimwe zvinhu zvakawanda. Kudzidzira kwakaratidza kuti, pasi pemamiriro akajairwa, ma mechanic zvimiro zvekukanda kufa nehukobvu hwemadziro hunowedzera nekudzikira. Mudhuri wakatetepa une simba rakakwirira uye density pane gobvu madziro castings, nepo mutete madziro anofa castings ane nani kupfeka kuramba. Sezvo kukora kwemadziro ekukanda kufa kunowedzera, hurema hwakadai semaburi emhepo uye porosity inoratidzwa mu b) inowedzerawo. Nokudaro, pasi pechikonzero chekuona kuti kufa kwekufa kune simba rakakwana uye kuoma, hukuru hwemadziro hunonzwisisika hunofanira kugadzirwa kuti huve hutete uye hwakafanana. Zvikasadaro, chimiro chemukati chekukanda kufa kuchave chisina kuenzana, chichawedzerawo kuoma kwekuitwa kweiyo kufa yekukanda maitiro. Pasi pemaitiro akajairika, kufa kukanda madziro ukobvu haapfuuri 4.5mm, hombe yemadziro ukobvu uye diki madziro ukobvu reshiyo) haina kupfuura 3 * 1. Kune gobvu-yakavezwa kufa kukanda, kuitira kudzivirira kusunungura uye kumwe kukanganisa, kunofanirwa kuve kwakatetepa madziro ukobvu uye kuwedzera chigamba.

Dimensional kurongeka kwekukandira kufa: kurongeka kwedimensional ndechimwe chezvinhu zvakakosha zvekugadzirwa kwefa yekukandira chimiro, inokanganisa dhizaini yekukanda mold dhizaini uye kufa kukanda maitiro. Die casting inogona kuwana iyo dimensional kurongeka kwakakwira, kugadzikana kwayo kwakanaka kwazvo, izvo zvinonyanya kuenderana nekugadzirwa kwechokwadi kwekufa kukandira mold. Pane zvikonzero zvakawanda zvekutsauka kwedimensional yekukanda kwekufa, kusanganisira kutsauka kwemakemikari anoumbwa nealloy pachayo, tembiricha yenzvimbo yekushanda, kuderera kweiyo shrinkage rate yealloy simbi, kugadzikana kwekufamba mamiriro uye zvichingodaro. Kuvhura kwechiumbwa kuburitsa musimboti uye kusundira kunze kwechigadziriso, pamwe nekushandiswa kwemaitiro ekuumba. Kukanganisa kunokonzerwa nekupfeka uye kubvarura, kutsauka kwekufa-casting process parameters, kufa-casting machine chaiyo uye kuomarara kunokonzerwa nekukanganisa, huwandu hwenguva uye hupenyu hwebasa rekugadzirisa mold, etc. Izvi zvikonzero zvinopindirana uye zvinokanganisa mumwe nemumwe, senge alloy shrinkage, zvichienderana nechimiro chekukandira kufa, kufa-casting process parameters, kukanda madziro emhando, kukanda madziro emhando. Naizvozvo, zvinodikanwa kuti udzidze hukama pakati pemamiriro ari pamusoro uye shrinkage rate kuitira kuti uone iyo chaiyo shrinkage rate.

Sarudzo yemutsara dimensional kushivirira mamakisi ekufa castings inoratidzwa muTafura 4-7 uye Tafura 4-8. Bhandi rekushivirira rinofanira kugoverwa zvakaenzana, kureva, imwe hafu yekushivirira yakanaka uye imwe hafu yakaipa. Kana asymmetric setting ikashandiswa, inofanira kuratidzwa pamufananidzo. Kune zviyero zvisingawanzo kugadzirwa, gomba rinotora kukosha kwakanaka uye shaft inotora kukosha kwakashata; nokuda kwezviyero zvinofanira kugadzirwa, gomba rinotora kukosha kwakashata uye shaft inotora kukosha kwakanaka.
