Paunonzwa impro investment casting, chii chinouya mupfungwa? Kune vanhu vazhinji, ingori chirevo-chimwe chivimbiso chisina kujeka chemhando iri nani kana mutengo wakaderera. Iro izwi rinokandwa kumativi ekutengeserana uye munzvimbo dzekutengesa, kazhinji pasina zvinhu zvakawanda. Muchokwadi, kuvandudza maitiro aya hakuzi nezve rimwe remashiripiti bullet; kuri kugaya. Zviri pamusoro pekuwedzera mhedzisiro yezana diki gadziriso mukamuri remateko, dhipatimendi rewax patani, uye pasi pekutanga. Vazhinji vanofunga kuti ndezvekutenga choto chitsva kana fancy 3D printer yemapateni. Icho chikamu chazvo, chokwadi, asi kana ganda rako risingaenderane kana dhizaini yako yekugezera isina kunaka, iyo michina mitsva ingori inodhura paperweight. Ndakaona zvitoro zvichidurura mari muzvinatsiridzwa zvisina kumbobvira zvafambisa tsono pamitengo yezvikara.
Nheyo: Inogara Nezve Shell
Ngatitorei chaizvo. Kana uchida kutaura nezvazvo impro investment casting, unofanira kutanga negoko. Apa ndipo panogara matambudziko mazhinji-nemikana. Ndinoyeuka ndichishanda panhevedzano yesimbi isina tsvina yemugadziri wepombi. Iyo spec inodaidzira kutetepa, aerodynamic vanes. Mwero yedu yezvikara yaive ichitenderera ichitenderedza 40% nekuda kweveining uye kuputika kwegoko. Isu takadzingirira vaimbofungidzira: slurry viscosity, stucco jecha gradation, kuomesa mukamuri humidity. Kubudirira kwacho kwakanga kusiri imwe mhinduro yepamusoro-soro; yaive ichicheka zvine hungwaru tembiricha yepakati panguva yega yega dip kutenderera kwemavhiki maviri. Takawana kudonha kwe5-degree Celsius panguva yekuchinja kwehusiku iyo yaikonzera kusawirirana kwebhachi rekutanga. Kudzikamisa izvo zvaive zvakachipa kupfuura chero midziyo mitsva uye kucheka zvimedu nehafu. Kuvandudza pano kunorwadza granular.
Izvi zvinobatanidza zvakananga kune unyanzvi hwekushanda kwenguva refu. Tora kambani yakafanana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Neanopfuura makore makumi matatu ekukandira uye kugadzira, vangangove vakararama kuburikidza neasingaverengeki iterations yehoko resipi tweaks. Kunyanya kwavo mune zvese shell mold uye Investment casting zvinoreva kuti vanonzwisisa zvinhu zvesainzi zvakadzama—mabatirwo anoitwa mabhaindi akasiyana-siyana, mavakirwo egoko remuviri mukuru wevharuvhu wesimbi maringe neyakapfava yecobalt alloy chikamu chekuvhiya. Rudzi irworwo rweruzivo rwemasangano ndiwo musimboti webudiriro chaiyo. Iwe haugone kuzvitenga kubva pasherufu.
Zvishandiso pachazvo zvinoraira nzira yekuvandudza. Kushanda ne nickel-based alloys? Yako goko rekupisa kwekuwedzera mbiri uye simba rinopisa rinove risingagone kutaurirana. Kuvandudzwa kudiki muhupfu hwezircon hwejasi rejasi rinogona kuve mutsauko pakati pekukanda ruzha uye imwe yakazara nemisodzi inopisa. Harisi basa rinoshamisira. Zviri pamusoro pevashandi vane makumi emakore eruzivo vachiziva, nekutarisa uye nekunzwa kwekusagadzikana, kana zvirizvo, nguva refu mhinduro dzebvunzo dzerabhu dzisati dzadzoka.
The Wax Room: Imo Dimensional Kuvimbika Kwahwina kana Kurasika
Wese munhu anotarisa pasimbi, asi wakisi patani ndiyo DNA yekukanda. Chero kukanganisa pano kunowedzera. Kuvandudzwa kwejekiseni ihondo yekurwisana nekushungurudzika kwemukati. Takamboita purojekiti yemabhuraketi emuchadenga uko kwatairamba tichiwana zvinyoro-nyoro, zvisina-uniform warpage mushure mekudonha. Iyo CAD modhi yaive yakakwana, iyo tooling yaive nyowani. Mupari wemhosva? Kudzvanywa kwejekiseni rewakisi uye nguva yekubata haina kugadziridzwa kune chaiyo geometry's volume-to-surface-area ratio. Taifanira kugadzira raibhurari diki yejekiseni paramita kune akasiyana emhuri-ye-zvikamu maumbirwo. Zvainetesa, asi zvakabvisa bviro huru yekukukurwa.
Apa ndipo panobatanidzwa nemachining, senge QSY's yakasanganiswa Investment casting uye CNC kugona, inoratidza kukosha kwayo kwehunyanzvi. Kana iwe uchigona kuburitsa padhuze-net-shape wakisi pateni kuburikidza nechaiyo machining yeatenzi kufa, iwe uri kutanga kubva kune yakanyanya kutendeseka yekutanga. Kuvandudzwa kwakabikwa mukati mekutanga. Zvadaro, chero inotevera CNC machining pane yekupedzisira simbi chikamu ishoma, kuchengetedza kutendeseka kwezvinhu uye kuchengetedza mutengo. Ndiyo maonero akazara echeni yekugadzira.
Chimwe chinhu chinowanzo furatirwa kuungana kwewakisi. Unyanzvi hwemaoko hwemawelder kuunganidza miti yewakisi hunokanganisa goho. Gedhi risina kukona kana kuti simbi isina simba inokonzera kupera kwesimbi kana kukanganisa. Kudzidzira uye nyore jigging pano inopa kudzoka kukuru. Ndakaona kuti kurekodha kwevhidhiyo nzira yevashandi vane hunyanzvi uye nekuishandisa kudzidzisa kwakavandudza kuenderana kupfuura chero otomatiki system yataigona kuwana panguva iyoyo.
Iyo Melt uye Dururira: Kudzora Pamusoro Pemhirizhonga
Apa ndipo panosangana dzidziso nemoto. Iwe unogona kuve negoko rakakwana uye rakakwana wakisi pateni, uye kudira kwakashata kunoparadza zvese. Kwandiri, kuvandudza maitiro ekukanda pachawo ndeye hutsinye kumira uye kunzwisisa iyo fizikisi yekuzadza. Iine yakakwirira-tembiricha alloys senge cobalt-yakavakirwa iwo, superheat kutonga kwakakosha. Madhigirii mashoma akanyanya kukwira, uye iwe unowedzera simbi-shell reaction; zvakaderera, uye unogona kukanganisa kusanzwisisana.
Takaita shanduko iri nyore asi inoshanda yekudira turbine blades: kushandura kubva pakudonha kwemahara kudira kune inodzorwa, yakamanikidzwa kurerekera kudira pasi pegumbeze diki reargon. Kudzikiswa kwemhirizhonga uye kuumbwa kweoxide kwakakurumidza kuoneka mumaradiographs. Iko kunatsurudzwa kwanga kusiri mumidziyo (kunyangwe iyo yekudururira mudziyo waive wakagadzirwa) asi muhuzivi - yekutanga laminar izere nekumhanya. Iyi ndiyo mhando yemaitiro nuance iyo yakawanda-makumi emakore foundry inounganidza.
Post-casting, iyo yekugogodza-kunze ndiyo imwe nzvimbo yengozi. Ndakaona madhirigi anoyevedza akatsemuka nekuzunguzika kwakanyanyisa kana jeti remvura rakakwirisa zvakanyanya. Kuvandudzwa kwaireva kugadzira yakapfava, yakanangana nemidziyo yekushongedza, dzimwe nguva kunyangwe kemikari leaching yezvemukati-zvakaoma ndima. Kunonoka, kudzokorora curve yekudzidza.
CNC Machining: The Critical Finish Line
Uyu ndiwo mubhadharo. Yakagadzirwa zvakanaka Investment casting inofanira kuda kushoma machining. Asi zvishoma hazvirevi kuti hapana. Iyo interface pakati peiyo yekutanga uye muchina shopu ndipo panonongedzwa zvigunwe. Iko kunatsiridza chaiko kunobva mukuronga kare. Semuyenzaniso, pane yakabatanidzwa oparesheni senge QSY, ivo CNC programmers vangango bvunzana neakatanga mainjiniya panguva yekutanga gating dhizaini. Ivo vanobvumirana pane datum mapoinzi, wedzera kushoma machining stock munzvimbo dzakaoma, uye dhizaini zvigadziriso zvinonongedza kukanda-kukanda maficha, kwete chete CAD modhi.
Ndakadzidza izvi nenzira yakaoma. Takambokanda nhevedzano yemarine-giredhi Stainless simbi fittings. Kukandira kwacho kwaive kwakanaka, asi chitoro chedu chemuchina chakanetsekana nekuti gedhi rekutanga rakasiya chitubu chaikanganisa kuseta kwakajairika. Musangano wemaawa maviri pakati pekukandira uye machining anotungamira kusati kwaitwa mudziyo ungadai wakachengetedza mazuva ekugadzirisa zvakare gare gare. Kuvandudza ndeyekuputsa masiro edhipatimendi.
Kune yakaoma alloys, machining zano chikamu chekuvandudza. Kuziva kuti nickel-based alloy casting ine zvishoma, kushanduka kwepamusoro kuoma kubva pakusangana kwegoko zvinoreva kuti chirongwa chako cheCNC chinofanirwa kuve nekuchekwa kwekutanga. Ruzivo urwu rwunobva mukudyisa kumashure machining data (yezvishandiso zvekupfeka mitengo, pamusoro pekupedzisira mhinduro) kune yekutanga timu, kuvhara loop.
Chiyero Chaicho: Kuenderana uye Kuvimba
Saka, chii chinopa impro chaizvo? Haisi kazhinji chimurenga chitsva chigadzirwa. Iko kugona kurova CTQ (Critical-to-Quality) dimension pane yakaoma chikamu, batch after batch, kondirakiti inotora makore gumi. Ndiko kuvimba kunoiswa mauri nemutengi senge mudziyo wekurapa kana mugadziri wemidziyo yesimba. Havana basa neruoko rwako rutsva rwerobhoti; vane hanya kuti chikamu chimwe nechimwe mugungano ravo chinokwana uye chinoita.
Iyi ndiyo nzvimbo iyo kambani inovaka mukurumbira wayo. Makore makumi matatu mubhizinesi, seQSY, anoratidza kuti vakafamba-famba uku kuwedzeredza kuvandudzwa kwakabudirira pakuchinja kwezvinhu uye kutenderera kwemusika. Basa ravo rine alloys akakosha rinondiudza kuti vakagadzirisa matambudziko akaomarara - kudzora chimiro chezviyo muzvikamu zvakakura zvekukanda, kugadzirisa zvakasara kushushikana, kuwana X-ray mhando welds payakagadziriswa castings (kana ichibvumidzwa ne spec).
Pakupedzisira, kuvandudza kuisa mari ipfungwa. Kuzvipira kuchera muyero ye40% yezvimedu musi weChishanu masikati uye kwete kusiya kusvika iwe uine hypothesis yekuyedza neMuvhuro. Iko kukoshesa intuition yemhizha zvakanyanya sekuverenga kwe spectrometer. Iko kunatsiridza kwakanyarara, kwakavakirwa mumaitiro ezuva nezuva, uye kunoratidzwa mumurwi uri kukura weakabudirira kutumirwa maodha ezvikamu hapana mumwe munhu anoda kubata. Ndiyo bhenji chaiyo.
