Gravity die casting, inozivikanwawo sezvachose mold kukandakana chill casting, inzira yakakurumbira yekukanda inoshandiswa kugadzira zvinhu zvesimbi mumhando dzakasiyana dzemaindasitiri. Kusiyana nejecha kukanda uyeInvestment casting, gravity die casting inoshandisa molds inogona kushandiswa zvakare yakagadzirwa nesimbi kana simbi yakakandwa, iyo inopa huwandu hwepamusoro hwekururama uye kupera kwepamusoro. Muchinyorwa chino, tichakurukura nezve giravhiti kufa kukanda maitiro ekuyerera chati, mabhenefiti ayo, uye mashandisiro.
Gravity Die Casting Process Flow Chati:
Iyo gravity die casting process flow chart inogona kukamurwa kuita matanho akati wandei, kusanganisira kugadzirira mold, kunyungudika kwesimbi, kuungana kwe mold, kukanda, kupedzisa, uye kuongorora. Pazasi pane tsananguro yedanho rega rega:
- Kugadzirira Mold:
Danho rekutanga mugwara rekukanda giravhiti nderekugadzirira mold yekukandira. Iyo mold inowanzogadzirwa nesimbi kana simbi yakakandwa uye yakagadzirirwa kuburitsa inodiwa chimiro chechigadzirwa chekupedzisira. Iyo chaiyo yekukanda isati yatanga, mold inofanira kunyatsocheneswa uye kuongororwa kuti ive nechokwadi chekuti hapana chakaremara kana kukanganisa. Chero kugadziriswa kunoda kuitwa kune mold kunofanira kuitwa panguva ino.
- Metal Melting:
Kana mold yagadzirwa, danho rinotevera nderokunyungudutsa simbi inodururwa muforoma. Zvichienderana nerudzi rwesimbi inokandwa, mavhiri akasiyana-siyana anogona kushandiswa kuita izvi, kusanganisira magetsi arc furnaces, induction furnaces, uye gasi-fired cupolas. Iyo simbi inowanzo kudziya kusvika kune tembiricha pamusoro penzvimbo yekunyungudika, uye chero tsvina kana alloying agents anowedzerwa panguva ino.
- Mold Assembly:
Mushure mokunge simbi yakanyungudutswa, mold inounganidzwa uye yakagadzirirwa kukanda. Iyo mold inowanzo umbwa nehafu mbiri, imwe hafu ichimira uye imwe hafu ichifambiswa. Iwo mahafu maviri akabatana uye akasungirirwa pamwechete, uye chero anodiwa egeji kana masisitimu ekusimudza anowedzerwa kuti ave nechokwadi chekuyerera kwakanaka kwesimbi muforoma.
- Kukandira:
Kana mold yaunganidzwa, simbi yakanyungudutswa inodururwa muforoma kuburikidza nenhevedzano yemagedhi nezvikwiriso. Iyo simbi inozadza mhango ye mold uye inosimbisa, ichitora chimiro chechimiro. Simba rinokwevera zvinhu pasi rinoshandiswa kumanikidza simbi kuti ipinde muforoma, ndosaka nzira iyi ichinzi gravity die casting.
- Kupedzisa:
Mushure mekunge simbi yasimba uye yatonhorerwa pasi, mold inovhurwa, uye kukanda kunobviswa. Chero chipi zvacho chakawandisa kana flash inosara pakukandwa inochekwa uchishandisa akasiyana maturusi ekupedzisa senge masaha, grinders, uye sanders. Iyo yekukandira inozocheneswa nekukwenenzverwa kuti isvike painoda kupera kwepamusoro.
- Kuongorora:
Danho rekupedzisira mukukandira giravhiti kufa kuri kuongorora. Iko kukanda kunoongororwa zvakakwana kune chero kukanganisa kana kusakwana senge makatsemuka, voids, kana porosity. Chero chakakanganisika chinowanikwa chinogadziriswa, uye kukanda kunotariswa kekupedzisira kusati kwatumirwa kune imwezve kugadziriswa kana kuungana.
Zvakanakira zveGravity Die Casting:
- Kururama kwepamusoro uye kugadzikana kwedimensional
- Yakanakisa kupedzwa kwepamusoro uye kugadzirisa kweruzivo
- Inokurumidza kugadzira nguva zvichienzaniswa nekukandira jecha kana kuisa mari
- Inodhura-inoshanda kune yakawanda yakawanda yezvikamu
- Inokodzera huwandu hwakawanda hwesimbi dzinosanganisira aluminium, mhangura, uye ndarira.
Zvishandiso zveGravity Die Casting:
Gravity die casting inoshandiswa mumhando dzakasiyana siyana dzemaindasitiri uko kunodiwa zvemhando yepamusoro simbi zvikamu. Mimwe mienzaniso yakajairika inosanganisira:
- Zvikamu zvemotokari zvakaita semabhuraki einjini, misoro yemasilinda, uye makesi ekutapurirana
- Zvikamu zvemuchadenga senge turbine blades uye zvimiro zvikamu
- Zvinhu zvemagetsi zvakaita sematransformer, switchgear, uye conductor
- Michina yemaindasitiri senge pombi, mavharuvhu, uye fittings
- Midziyo yemitambo yakadai semakirabhu egorofu, hove reels, uye mafuremu emabhasikoro.
Mhedziso:
Gravity die casting inzira inoshanda uye inodhura yekugadzira zvinhu zvesimbi zvine kupedzisa kwepamusoro uye kurongeka chaiko. Iine mabhenefiti ayo akawanda pamusoro pemamwe maitiro ekukanda, giravhiti kufa kukanda isarudzo yakakurumbira kune dzakasiyana siyana dzekushandisa maindasitiri. Nekunzwisisa kuyerera kwechati yegiravhiti kufa yekukanda maitiro, vagadziri vanogona kuona kuti zvigadzirwa zvavo ndezvemhando yepamusoro uye zvinozadzisa zvinodiwa nevatengi vavo.
