Precision casting inzira yakajairika yekukanda muvagadziri vesimbi, asi kusimudzira kwazvino hakuna kujairika sekukanda simbi uye kukanda simbi, asi kukanda chaiko kunogona kuwana chimiro chakaringana uye chakanyanya kukanda kurongeka.
Iyo yakajairika nzira yekukandira chaiyo ndeyekugadzira chigadzirwa mold zvinoenderana nedhirowa.Musiyano uripo pakati pekukandira kwakaringana nekukanda simbi ndeyekuti kukanda kwesimbi kunofanirwa kuve nekumwe kumucheto kwekugadzirisa, nepo chaiyo yekukanda inogona kuva nemargin kana kwete.Iyo yekutanga wakisi pateni inowanikwa nekukanda, uye ipapo maitiro ekuputira uye sanding anodzokororwa. pamuenzaniso wewakisi.Mushure mekunge goko rakaomeswa raomeswa, chimiro chewakisi chemukati chinonyunguduka.Iyi nhanho iri dewaxing, kuitira kuti tiwane mhango; Mushure mekubikira goko, tinogona kuwana simba rakakwana uye kupera kwemhepo.Ipapo tinogona kukandira mvura yesimbi inodiwa mugomba.Mushure mekutonhora, tinogona kubvisa shell uye kubvisa jecha, kuitira kuti tiwane yakakwirira-yakanyatsogadzirwa zvigadzirwa.
Investment casting process:
1. Maererano nezvinodiwa zvemifananidzo yemushandisi, mold yakakamurwa kuva yepamusoro uye yakaderera concave mold, iyo inopedzwa nekugaya, kutendeuka, kuronga uye mamwe maitiro.Chimiro chegomba reforoma chinofanira kuenderana nehafu yechigadzirwa.Nekuti mold yewakisi inonyanya kushandiswa kugadzira wakisi yemaindasitiri, tinoda kusarudza aruminiyamu alloy zvinhu nekuoma kwakaderera, zvinodiwa zvakaderera, mutengo wakaderera, uremu hushoma uye hushoma. kunyungudika se mold.
2. Mushure mekusarudza yakanaka aruminiyamu alloy zvinhu, tinogona kushandisa iyi aruminiyamu alloy kugadzira nhamba huru yeindasitiri wax yakasimba mienzaniso.Pasi pemamiriro ezvinhu akajairika, mold yakasimba yeindasitiri wax inogona kungoburitsa chimwe chinhu chisina chinhu.
3. Kana wakisi patani yagadzirira, zvinodikanwa kushandura mupendero wakatenderedza wakisi pateni.Mushure mokubvisa zvinhu zvakanyanyisa pamusoro pepamusoro, zvakakosha kunamatira imwe wax pattern pamusoro wakagadzirirwa.
4. Tine nhamba yemusoro wewakisi wakaputirwa nenamo yeindasitiri, wozopfapfaidzwa zvakaenzanirana nejecha rejecha risingasviki pamoto uye rinokwanisa kupisa tembiricha yakawanda. Rudzi urwu rwejecha idiki uye rakanaka, rinogona kuve nechokwadi kuti nzvimbo yekupedzisira yechinhu chisina chinhu inotsvedzerera.
5. Zvadaro isa muenzaniso wakisi mufekitari yatinoisa tembiricha yekamuri yekuomeswa kwemhepo, asi haifanire kukanganisa kuchinja kwechimiro chemukati wewakisi.Nguva yekuomeswa kwemhepo yakasikwa zvinoenderana nekuoma kwemukati kwe mold.Kazhinji kutaura, nguva yekutanga yekuomesa mhepo inenge maawa 5-8.
6. Kana patani yewakisi yaomeswa nemhepo, panodiwa musara wenamo wemuindasitiri pamusoro pepatani yewakisi, uye chikamu chechipiri chejecha chinopfapfaidzwa pamusoro.Zvimedu zvejecha muchikamu chechipiri zvakakura uye zvakakora pane zviri muchikamu chekutanga. Mushure mekubata chikamu chechipiri chejecha, sechikamu chekutanga, omesa mweya chaiwo.
7. Mushure mekunge chikamu chechipiri chejecha chakaomeswa zvakasikwa, chechitatu, chikamu chechina uye chechishanu chekuputika kwejecha chichaitwa zvakatevedzana.Sandblasting zvinodiwa: tinoda kugadzirisa nguva dzejecha maererano nezvinodiwa pamusoro uye huwandu hwejecha. chigadzirwa.Muzhinji, kuwanda kwejecha kunenge kunenge 3-7 nguva.Kukura kwechidimbu chejecha rimwe nerimwe rakasiyana, jecha remaitiro ega ega rinorema kudarika rakapfuura, uye nguva yekuomesa mhepo yakasiyanawo. nguva yejecha pane yakazara wakisi pateni inogona kunge iri mazuva matatu-4.
