Paunonzwa 'tilt gravity die casting', mufananidzo wekutanga unowanzoitika ndeuyu wakatsetseka, otomatiki maitiro ekudira simbi isina chainopomerwa. Muchokwadi, zvakanyanya kudzorwa, zano remaune. Pfungwa yepakati iri nyore: pachinzvimbo chekurasa simbi yakanyungudutswa yakananga pasi, unorereka mold kuti simbi izadze zvishoma nezvishoma, ichideredza kusagadzikana. Asi pano ndipo panosangana dzidziso pauriri hwechitoro - kuwana iyo yekumhanyisa kumhanya uye kona chaiko kune chikamu chakaomarara, kunyanya chine anonyengera alloys, ndipo panowanikwa makumi emakore eguruva rekutanga.
Iwo Mechanics eTilt uye Nei Isiri Gimmick chete
Ngatiparadzei 'tilt'. Hazvisi zvemuchina wemhando yepamusoro, kunyangwe iwo aripo. Zviri pamusoro kudzora pamberi simbi. Mukudururwa kwegiravhiti kwakajairika, unowana mapopoma emvura. Kune chimwe chinhu chakaita seimba yakatetepa-yakakomberedzwa nesimbi isina tsvina yevharuvhu, ndiyo nzira yekuisa oxide inclusions uye mhute inomhanya. The tilt process inoita kuti simbi ikwire pamadziro egomba. Funga kudira doro zvishoma nezvishoma maringe nekuritsveta mukati. Yekutanga inokupa musoro uri nani, wekupedzisira kukanganisa. Mumashoko esimbi, 'musoro' uri nani unoreva kuvharwa kwegasi kushoma uye chimiro chezviyo chakafanana.
Ndinorangarira basa ratakaita makore kumashure kwepombi impeller in duplex stainless. Mutengi aive nenyaya neshrinkage porosity muharare yepakati achishandisa nzira dzechinyakare. Takanetsana kuti tiite tilt approach. Kupokana kwekutanga kwaive nezvenguva yekutenderera - inononoka zvisingaite pakudira. Asi mubhadharo waiva mumutengo wakaderera wezvirasa. Nekurerekera, takanangisa nzvimbo yekupisa yekukanda zvakanyanya kufanofungidzira, izvo zvakaita kuti kuisa kutonhora uye kusimuka kuve chiitiko chesainzi kwete mutambo wekufungidzira. Goho rakavandudzwa nezvikamu gumi neshanu muzana, izvo pamutengo wezvinhu izvozvo, zvakaruramisa kudira kunononoka.
Kwainonyatso penya kune aya akakosha alloys QSY anowanzo kubata, senge nickel-based. Aya ma viscous, anosimba nekukurumidza, uye anodhura. Iwe haugone kubhadhara mhirizhonga inotungamira kune inclusions iwe unongowana panguva yekugadzira. Kurerekera kunova chinhu chinodiwa, kwete sarudzo. Iyo imhinduro inoshanda yekudzora kuzadza nenzira iyo yakatwasuka kudira kazhinji haigone kuenderana neakaomesesa geometries.
Material Matters: Haisi Imwe-Tilt-Fits-All
Uku kutarisisa kwakafanana. Iyo inorereka paramita yegrey iron inyika yakaparadzana neiyo yecobalt-based alloy. Nesimbi yakakandwa, uri kubata nekunaya kwakanaka asi tsika yekuumbwa kwemarara kana kudira kwakanyanyisa. Kumhanya kuri pakati nepakati kunoshanda. Asi chinja kune yakakwira-nickel alloy, uye mutambo unoshanduka. Simbi iyi 'ipfupi', haifambire nyore nyore. Unoda nhanho yekutanga yekurerekera kuti simbi ifambe, wozoita inononoka, inodzorwa kupera kudyisa zvikamu zvinoomesa kwekupedzisira.
Takadzidza izvi nenzira yakaoma pachirongwa chekutanga chebhureketi rinodzivirira kupisa. Kushandisa iron-optimized tilt program pane nickel-chromium alloy yakakonzera kuvharika kunotonhora kumucheto kwegomba. Simbi yaivhizuka isati yazara. Kugadzirisa kwanga kusiri kungomhanyisa kutenderera; kwaive kusati kwapisa kufa kwakasiyana uye kutanga kurerekera zvine hukasha kuti uwane kumhanyisa kumberi, wozodzikisira pasi. Kutamba uku pakati petembiricha, kukurumidza kutenderera, uye kona yaunowana chete kubva mukupusha nguva shoma.
Apa ndipo panowanikwa ruzivo rwezvinhu, senge makore makumi matatu-asinganzwisisike QSY inotaurwa, inobatika. Hazvisi zvekungova nemidziyo chete; ndezvekuva nekurangarira kwemaitiro kune izvo zvinoshanda neInconel 718 maringe ne304 isina tsvina. Maitiro ekurerekera anokudza kukosha kwezvisina kujeka izvi. A generic maitiro anokupa generic, kazhinji isina kukwana, mhinduro.
Kushandisa uye Kufa Dhizaini: Iyo Gamba Risina Kusukwa
Iyo die dhizaini yekukanda tilt yakasiyana zvakanyanya. Iyo gating uye mumhanyi sisitimu iri nyore mune dzimwe nzira nekuti hausi kutsamira pane yakaoma sisitimu yekudzora kuyerera - iyo tilt inoita izvozvo. Asi iwe unofanirwa kufunga maererano nenzira yesimbi sezvo kufa kunotenderera. Iyo ingate inoda kuiswa kuitira kuti ive nzvimbo yakaderera pakutanga kwekurereka, uye mhepo yekufema inofanirwa kushanda mukati mekufamba kwese kutenderera, kwete kungozadzwa kwakamira.
Ndakaona inofa apo mavhavha akaiswa zvakakwana kuti adire yakatwasuka asi ikava misungo isina basa yemhepo yakamborereka 45 madhigirii. Iwe unopedzisira uine homwe dzegasi munzvimbo dzisingaite. Mhinduro yacho inowanzo sanganisira akawanda, madiki mamhepo padivi pemutsara wekuparadzanisa uye dzimwe nguva kunyange zvenguva pfupi mavheti e ceramic panzvimbo dzakakwirira dzenzvimbo yekutanga kufa. Zvakashatisa, zvinoshanda kugadzirisa matambudziko.
Kufa upenyu chimwe chinhu. Iko kunonoka, kunogara kunobata simbi inopisa ichikwira rusvingo rwekufa kunogona kutungamirira kune akasiyana-siyana ekuneta kwekupisa zvichienzaniswa nekuvhunduka kwekudira kwakazara. Isu tinowanzo kuona zvakanyanya kunaka, kupisa-cheki kupaza munzvimbo dzekutanga dzekuzadza nekufamba kwenguva. Zvinoreva kuti chirongwa chako chekugadzirisa kufa chinoda kuzvidavirira pane izvi. Haisi nzira yekuisa-iyo-uye-kukanganwa-iyo; inoda kutariswa zvakanyanya kune iyo tooling mamiriro kutenderera-ku-kutenderera.
Kubatanidzwa neSekondari Maitiro: Iyo Machining Link
Uyu ndiwo mubairo wakakomba. Yakagadzirwa zvakanaka tilt gravity die casting haisi yekupedzisira chigadzirwa; iri pedo-net-shape preform yeCNC machining. Kusagadzikana kwainounza ihope dzemuchina. Kana iko kunzwika kwemukati uye kushomeka kwezvakaomesesa zvinosanganisirwa zvinofanotaurwa, unogona kusundira iyo CNC feed uye nekumhanyisa zvakanyanya. Iwe hausi kunetseka nezvekurova homwe yejecha kana sumbu remaokisi rinopwanya chigayo chemadhora mazana maviri.
Pane imwe nzvimbo inobata zvese kukanda uye machining mumba, senge yakasanganiswa setup inokurudzirwa neQSY's masevhisi, iyi synergy yakakura. Chikwata chekukanda chinoziva chaizvo izvo machinists anoda maererano nenzvimbo dzedatum, mari shoma yekubvumidza, uye kufanana. Kana iwe uchidzora kuzara nekureruka, iwe unowana zvakanyanya kufanofungidzira shrinkage, zvinoreva kuti iwe unogona kuisa chikamu mufa kuti uderedze kunotevera machining kukanganisa. Inoshandura mashandiro maviri akapatsanurwa kuita kumwe kuenderera mberi kwekushanda.
Muedzo chaiwo uri pamushini wekuyeresa (CMM). Zvikamu zvinobva pakudururwa zvine mhirizhonga zvinowanzo ratidza mutsauko usingaenderane nekufa - ndiko kushushikana kusingaite kubva mukutonhodza kusina kuenzana. Tilt-cast zvikamu, mune yangu ruzivo, ratidza mapatani. Kana paine kutsauka, inodzokororwa uye inoteedzerwa kudzoka kune kufa deflection kana yekupisa mbiri, chiri chinhu chaunogona kunyatso mainjiniya kugadzirisa.
Kuganhurirwa uye Chaiyo-Nyika Kukanganisa
Harisi bara remashiripiti. Chidziviso chikuru chikamu geometry. Makomba makadzika, matete? Tough. Simbi inogona kurasikirwa nekupisa kwakanyanya isati yasvika pasi. Dzimwe nguva iwe unofanirwa kusanganisa tilt nekashoma counter-gravity kubatsira kana kushandisa inopisa kufa kwekuwedzera. Inowedzera kuoma. Kune akareruka, chunky zvikamu, mutengo uye nguva yetilt system inogona kusaruramiswa. Nzvimbo inotapira inhengo dzepakati-kuoma uko kutendeseka kwakakosha.
Nguva yekutenderera, sezvataurwa, yakareba. Chikamu chekudira chinononoka, uye dzimwe nguva kufa kunoda kubatwa pane mamwe makona panguva yekusimba kubatsira kudya, izvo zvinosunga muchina. Nokuda kwepamusoro-soro, zvinhu zvisingadhuri, izvi zvinokanganisa. Iyi nzira ndeyemavhoriyamu akaderera, epamusoro-kukosha zvikamu. Funga zvigadziriso zvemuchadenga, mavharuvhu emiviri, yepamusoro-inoshanda zvinhu zvemotokari - nzvimbo dzinotariswa neQSY zvinhu.
Pakupedzisira, pane chikonzero chemunhu. Iyo yakanyanya nuanced maitiro kuseta uye kutarisa. Mushandi anofanirwa kunzwisisa zvaari kuona mukuzadzwa uye kupihwa simba rekuita micro-kugadzirisa. Iyo ishoma otomatiki pane iyo robhoti inodururwa mune yakamira kufa. Uri kutengesa kumwe kushanda kwakajeka kwekutonga uye kunaka. Mumusika wanhasi, kune chikamu chakakodzera, ndiko kutengeserana kwakawanda uye kwakawanda mainjiniya anoda kuita. Chinangwa hachisi kungokanda; chinhu chakavimbika, chinogoneka chikamu chisingakundike mumunda. Uye kazhinji, izvo zvinotanga nekureruka, nekuchenjera kurereka.
