Chii chiri kufa kukanda
Dife casting chiitiko chinogadzira chinoshandiswa kuburitsa zvidimbu zvesimbi zvine huwandu hwakanyanya hwekunyora uye kupedzisa kumuka. Izvo zvinosanganisira kumanikidza simbi yakanyungudutswa kuita cavity yekuumba pasi pekumanikidzwa kwakanyanya. Iyo Mold Cavity inogadzirwa neye maviri akaomeswa simbi anofa ayo anowana muchimiro chaunoda.
Maitiro acho anotanga nekunyungudika kwesimbi, kazhinji aluminium, zinc, kana magnesium, muchoto. Iyo yakanyungudutswa simbi inozoiswa mukati meiyo mold pakumanikidza ichishandisa hydraulic prin. Simbi inosimbisa nekukurumidza mukati meiyo mold, uye mafuro maviri emuumbi anovhurwa kuburitsa chikamu chakapera.
Dife casting inoshandiswa zvakanyanya kugadzira zvikamu zvine mwero akaomesesa uye madziro akaonda, senge madziro einjini, dzimba dzekutakura, uye dzakasiyana siyana uye dzakasiyana-siyana dzevatema uye dzemagetsi. Maitiro acho zvakare anozivikanwawo mukugadzirwa kwezvinhu zvekutengesa, sekuti sematoyi, kichchware, uye zvemagetsi.
Kumanikidza kufa kukanda
Dife casting is a clautly specialed maitiro ayo akagadzira zvakanyanya mukati mezana ramakore re20. Maitiro ekutanga ane: yakanyungudutswa simbi inodururwa Kazhinji, magadzirirwo amene anotora mashoma masekondi uye inzira inokurumidza yekuumba chigadzirwa cheSimbi kubva kuzvinhu zvakabikwa. Dife casting inokodzera zvinhu zvakadai se tin, lead, zinc, aluminium, magniyum, magniyamu kuenda kumhaphori alloys uye kunyange areollys simbi simbi isina tsvina. Alloys huru yakashandiswa nhasi mukumanikidza kufa kuchikanda ndeye aluminium, zinc uye magnesium. Kubva pane zvekutanga kufa zvakakanda michina dzakateedzerwa zvigadziko zvekutungamira mumatare emutungamiri wechiitiko uye kushanda, kuita zvizere zvemakomputa
Iyo indasitiri yakura mumushini wepasi rose kugadzira, kugadzira zvikamu zvakasiyana-siyana zvikumbiro, zvakawanda zvacho zvichave zvichisvika kubva kune wega sechigadzirwa chekushandiswa kwefekisikoka.
Zvakanakira kumanikidzwa kufa kukanda
Zvimwe zvezvakanakira zvekumanikidza zvakadzvanywa zvinokanda:
• Maitiro acho akakodzera kuvhomora kukuru kugadzirwa.
• gadzira zvisingaiti castx castings akakurumidza kuenzaniswa nedzimwe simbi yekugadzira maitiro (semuenzaniso.
• Yakakwirira simba zvikamu zvakagadzirwa mune yakakandwa mamiriro (pasi pecomputer dhizaini).
• kudzokorora kwakadzokororwa.
• Zvidimbu zviteteki zvinokwanisika (semuenzaniso. 1-2.5mm).
• yakanaka mutsara kushivirira (semuenzaniso. 2mm / m).
• yakanaka nzvimbo yekupedzisa (semuenzaniso. 0.5-3 μm).
Maitiro ekupota anopisa anofa anokandira anosanganisira kunyungudika kwesimbi ingangoita muchina wekukanda mongororo kuburikidza neyekunyungudika simbi zvakananga kuburikidza nejasi uye muchishandiso uye mune yekufa uye mune yekufa. Iyo gooseeck uye nozzle inoda kupisa kudzivirira simbi kusimuka isati yasvika kune iyo inofa cavity, iyo yakazara yekudziya uye yakaumbwa simbi yechiitiko ichi chinobva kune iyo nzvimbo inopisa inobva. Iyo yekukanda yakarongedzwa uremu yakadzvanywa nehuremu, urefu uye diamita yePlunger pamwe neiyo sleeve / kamuri size uye nekamuri yacho zvakare inotora chikamu chinofanira kutariswa pamusoro pekufa. Kamwe chete simbi yakasimbiswa mufekisi yemasekisi Zviso zvekufa zvinobva zvaita lubricated kuburikidza nehurongwa hwekupfira, iyo inofa inovhara uye maitiro ekutora zvakare.
Nekuda kweichi "chakavharwa" mesimbi melt / jekiseni system uye mashoma mechancal sangano rinopisa kufa rinogona kupa hupfumi hwakanaka hwekugadzira. Zinc Simbi Alloy inoshandiswa mukupisa mukamuri yekuvhara iyo ine yakadzika yekunyora Pollows (Sollever
Iro zita rinotonhora rinobva pamaitiro esimbi yakanyungudutswa muchimiro chesimbi, pfumo rakabatanidzwa kuburikidza nehafu yakatarwa yekufirwa nehafu yakatarwa yekufa. Yakanyungudika simbi inobata Tip-plunger Iyo yekufa inokanda muchina kana yakurudzirwa ichaita nhanho yekutanga kusundira simbi yakanyungudutswa yapfuura gomba rekudurura mumarara. Mamwe matanho anoitika pasi pekuwedzera hydraulic matambudziko kubva kugondohwe kuti jekese simbi yakanyungudutswa mune iyo inofa cavity. Maitiro ese anotora masekondi, kukurumidza uye kuwedzera kudzvanywa pamwe nekudonha kwesimbi tembiricha kukonzera simbi kusimbisa mufefiti. Iyo yekufamba hafu yekufa kwemushini wekukanda muchina anovhura (ndeipi iyo hafu yekufamba kwechombo chefe die yakagadziriswa kuenda) uye inokwereta yakasimbiswa kubva pane iyo face yechisimba. Iyo yekukanda inobviswa, iyo yechiso kumeso yakarongedzwa nehurongwa hwekupfira uye ipapo kutenderera kunodzokororwa.
Chamamati chamember chakakodzera kuti aluminium die casting, zvikamu pamushini (akapfura sleeve, plunger tip) anogona kutsiviwa nekufamba kwenguva, marara anogona kuve simbi abatwa kuwedzera kusimba kwavo. Aluminium Alloy yakanyungudutswa mune ceramic inowanzoitika nekuda kweiyo Aluminium yakanyanya kunyungudika pfungwa uye kukosha kwekuderedza njodzi yesimbi iyo inzvimbo inokwana mukati merembudzi. Nekuti Aluminium ishandare yechiedza chesimbi inokandira yekukanda yakakura uye inorema die casted kana kuti kune simba rakawanda uye mwenje mune die castings inodiwa.
