Kana vanhu vazhinji vakanzwa 'yakarasika yewakisi midziyo yekukanda', vanofananidzira mutsara unopenya, wakazviitira wega mukatalogi. Chokwadi chakashata, chakakamukana, uye hunyanzvi chaihwo huri mukuziva masonanidza zvidimbu izvozvo pamwechete kuita maitiro anoshanda zuva nezuva. Haisi kungobaya jekiseni kana muchoto; ndezvezvinhu zvisina kunaka zviri pakati-iyo inodzika autoclave inongoda iyo chaiyo yekumanikidza curve, kana slurry mixer ine paddle dhizaini inogona kugadzira kana kutyora goko rako. Mhosva yakajairika ndeyekudyara zvakanyanya mumuchina mumwe 'gamba' uchiregeredza masisitimu anotsigira anoutsigira. Ndakaona zvitoro zvine mamiriro-ye-the-art vacuum induction yekunyungudutsa choto chichinetsekana nekuti pre-heat station yavo yaisakwanisa kuwana mold kune inodziya tembiricha. Rondedzero yemidziyo ndeye symphony, kwete chiito chega.
Iyo Core Trio: Injector, Shell, Furnace
Ngatitangei newakisi jekiseni. Zvinoita sezviri nyore: nyungudutsa wakisi, jekiseni muforoma. Asi dhiyabhorosi ari muparameter. Kudzvinyirirwa kwemvura kune hydraulic system, tembiricha yekushisa muhari yewakisi, kunyangwe tembiricha iri mukamuri - zvese zvinokanganisa kugadzikana kwedimensional. Imwe chitoro chandakatsvaga yakanga ichiwedzera kukora kwemadziro kusingawirirani nemavhane emuchadenga. Zvinoitika, wavo ane makore makumi maviri midziyo yekukanda wakisi yakarasika— jekiseni rinoshandiswa nemaoko—rakashaya simba rokubata chairo. Isu takagadzirisazve dijitari pressure control valve. Dambudziko ragadziriswa, pachidimbu chemutengo wemuchina mutsva. Dzimwe nguva, ndezvekukwidziridzwa kwakangwara, kwete kutsiva kwekutengesa.
Zvadaro kunouya shell kuvaka. Iyo slurry musanganisi uye stucco sander ndiwo moyo pano. Vazhinji vanosarudza zvakachipa, off-the-sherufu paddle mixers. Kukanganisa kukuru. Kune inowirirana slurry viscosity, iwe unoda musanganiswa unogadzira laminar kuyerera, kwete vortex inoteya mweya. Isu takadzidza izvi nenzira yakaoma makore apfuura, tichirwisa mabhomba. Iye zvino, isu tinotsanangura ma mixers ane angled, scalloped paddles. Iyo stucco application ndeimwe yakavanzika art. Fluidized bed sanders akajairika, asi kune akakura kana anorema cores, mvura sander inopa kufukidzwa kuri nani. Idzi sarudzo, dzakavakirwa pane chikamu geometry, inoparadzanisa goko rakanaka kubva kune rakaremara.
The melting furnace ndipo panoperera zvese. Kunyangwe iri vacuum induction melting (VIM) yema superalloys kana mhepo yakapfava yakanyunguduka isina tsvina, crucible igamba rako risingafadzi. Kushandisa giredhi isiriyo ye zirconia-graphite crucible ine reactive alloys senge titanium-ine simbi isina tsvina inogona kutungamira kune yakashata kabhoni pickup. Ndinoyeuka bhechi remiviri yevharuvhu yechirimwa chemakemikari chakatadza kuongorora. Mupari wemhosva? A 'general-purpose' crucible. The midziyo yekukanda wakisi yakarasika zvakanaka; sarudzo inodyiwa yaive isiriyo. Ichi ndicho chikonzero ruzivo rwemutengesi zvakakosha. Kambani yakadai Qingdao Qiangsenyuan Technology (QSY), nemakumi matatu emakore avo Investment casting uye machining, aizonyatsonzwisisa izvi zvekushandisa-midziyo yekudyidzana. Haisi kungomhanyisa michina; vari kutarisira kemikari uye muitiro wekupisa.
The Inotsigira Cast: Ndeapi Catalogs Asikuratidze Iwe
Dewaxing. Vazhinji vanofunga nezvayo seyakapusa steam autoclave. Asi kukurumidza kuwedzera wakisi kunogona kutsemura mateko. Mazuvano midziyo yekukanda wakisi yakarasika pakuita dewaxing inoshandisa high-pressure, saturated steam ine controlled ramp-up rates. Isu takamboedza kucheka nguva yekutenderera nekumhanyisa kumanikidza nekukurumidza. Mhedzisiro? Muti wose wemablades eturbine wakatsemuka zvinonzwika—chidzidzo chinodhura. Ikozvino, isu tinobata dewaxing curve neruremekedzo rwakanyanya sekunyungudika curve.
Shell knockout uye kucheka-kubviswa. Ichi ndicho chikamu chine hutsinye. Matafura anozunguzika, sando dzemhepo—ibasa rine ruzha, rine huruva. Midziyo pano inoda kuve yakaoma, asi zvakare yakagadzirirwa kuderedza chikamu kukuvara. Iyo vibrator isina kunyatso kurongeka inokwanisa kutora zvinyoro zvinyoro pamasuwo avo. Isu takagadzira jig system inobata muti uchiri kudedera, ichitsaura pfungwa dzekushushikana. Ndizvo zvidiki, zvigadziriso zvetsika, zvinowanzogadzirwa mumba, zvinovandudza goho. Apa ndipo pane shop ine integrated CNC machining kugona, seQSY, ine mupendero. Ivo vanogona kukurumidza prototype uye muchina idzi tsika dzekugadzirisa zvigadziriso ivo pachavo, kuvhara loop pakati pekukanda uye post-kugadzirisa.
Material Dictates Machina
Alloy yako inotsanangura choto chako, chakajeka uye chiri nyore. Kudira cobalt-based kana nickel-based alloys? Iwe unenge uri munharaunda yeVIM yekudzora oxide inclusions uye uwane iyo inodiwa yakanyanya kupisa. Asi VIM haingori chidimbu chimwe chete midziyo yekukanda wakisi yakarasika; ihurongwa: pombi dzevacuum, magetsi, mvura inotonhorera, uye inodzorwa yekudira michina. Musiyano uripo pakati pekushanda kwakanaka uye kukuru kweVIM kunowanzo kuve muvacuum pombi kugadzirisa uye kuvuza kwemazinga. Kudonha kunononoka kunogona kuita oxidize kunyungudika iwe usati watombozviziva.
Kune masimbi ekabhoni uye akawanda magiredhi asina tsvina, kunyungudika kwemhepo muchoto chekusimudza-inorereka kunogona kukwana. Pano, iyo inotarisisa inoshandura kune kudzora mhepo (kazhinji nitrogen kana argon gumbeze) uye kubviswa kwe slag. Iyo refractory lining sarudzo inova yakakosha-yakasiyana kemikari kune basic vs. acidic slags. Iri ruzivo rwakadzama rwezvinhu runozivisa kusarudzwa kwemidziyo uye kushanda. Mutengesi akanyorwa masimba, senge QSY kushanda nayo special alloys, chiratidzo chakananga chezinga uye kuoma kwekunyunguduka kwavo uye kubata michina.
Kubatanidzwa uye Human Factor
Hapana mudziyo unozvifambisa wega. Iyo yakanakisa automated wax yekubatanidza robhoti haina basa kana mushandisi asinganzwisise maitiro ekuronga nzira dzeweld dzegeometri dzakasiyana dzegedhi. Ini ndinotenda mune otomatiki painoverengera - senge slurry dipping marobhoti kuti aite - asi kwete kwese. Dzimwe nguva, mhizha ine hunyanzvi ine wax welder uye ziso rakanaka rinogona kuunganidza muti wakaoma nekukurumidza uye zvinobudirira kupfuura kupedza maawa pane marobhoti programming. Chinokosha kuziva kuti ndezvipi zvinongedzo mumaketani kuti uite otomatiki.
Muedzo chaiwo we midziyo yekukanda wakisi yakarasika ndiwo mabatiro ainoita zvinhu zvisingatarisirwi. Simba rinopenya panguva yekunyunguduka, slurry batch ine zvishoma kubva pH, itsva wax kugadzirwa. Midziyo yacho inofanirwa kuve yakasimba uye, zvine musoro, iine zvinyorwa zvemanyorero. Ndakaona mutsara wakazara uchidzika kwemaawa nekuti sensor yakundikana. Chitoro chine chekare, semi-manual michina? Vakadarika sensor ndokupedza kumhanya. Tekinoroji inofanirwa kupa simba, kwete kuita nhapwa, maitiro.
Kutarisa Cheni Yese
Chekupedzisira, hazvionekwi kuona midziyo yekukanda uri wega. Chikamu chakakandwa kazhinji chingori chimiro chakakasharara. Ndipo panouya kudyidzana nemachining. Ko iyo yekukandira inoburitsa inowirirana datum nzvimbo yeCNC fixturing? Iyo yasara shell zvinhu zviri nyore kubvisa here? Sarudzo dzezvishandiso mune yekuwana zvinokanganisa zvakananga chitoro chemuchina kuzasi. Mupi wakanyatsobatanidzwa, uyo anobata zvose shell mold casting uye CNC machining pasi pemba imwe chete, iri kugadzirira rwendo rwese urwu. Ivo vari kuenzanisa maparamendi avo ekukanda uye gating dhizaini kuderedza machining nguva uye kupfeka kwezvishandiso. Ndiwo maonero akazara-chishandiso chinoshanda chekupedzisira, chakagadzirwa chikamu, kwete kungofanana-kukanda chimiro.
Saka pakuongorora midziyo yekukanda wakisi yakarasika, ingave yekutenga kana kuti pakuongorora mutengesi, tarisa kunze kwenzvimbo inopenya. Bvunza nezve dewaxing curves, slurry control, crucible manejimendi, uye mabatiro avanoita shanduko kuenda kumachina. Mhinduro dzichakuudza zvakawanda nezve kugona kwavo chaiko kupfuura chero bhurocha ripi zvaro. Iri mune gritty, yakabatana ruzivo rwemaitiro apo mhando inokandwa zvechokwadi.
