Kana vanhu vazhinji vakanzwa 'zvigadzirwa zvekuisa mari,' vanofungidzira izvo zvisina mhosva, pedyo-neti-shape turbine blades kana zvishongo zvakaoma kunzwisisa. Ndiyo gloss yekushambadzira. Chokwadi chiri pauriri hwechitoro inhaurirano dzinogara dziripo pakati peiyo yakanaka geometry pamuenzaniso weCAD uye fizikisi yakasindimara yesimbi yakanyungudutswa uye magomba eceramic. Pfungwa isiriyo huru? Kuti inzira 'yechokwadi' murabhoritari isina utachiona. Iyo chaiyo inozvarwa kubva kune inodzorwa mhirizhonga, ruzivo, uye yakawanda yekugadzirisa matambudziko isingamboite kune iyo spec sheet.
Iyo Core Yekuita: Zvese Nezve Shell
Wese munhu anotarisa pamusoro pechikamu chesimbi chekupedzisira, asi iwo mashiripiti chaiwo-uye bviro yemusoro wakawanda-inoitika mukamuri rehombodo. Hunhu hwe a Investment casting yakavharirwa mukati panguva yekutevedzana dips uye stuccos. Ndakaona mapurojekiti achikundikana nekuti dova harina kudzorwa panguva yekuomeswa, zvichitungamira kune madiki-makororo anongoonekwa mushure mekudirwa. Haisi yekungotevera resipi; ndezvekuverenga mukamuri, chaizvo. Kunyorova kubva pazuva rekunaya kwemvura kunogona kukudzosera kumashure maawa makumi maviri nemana.
Panzvimbo yakadai Qingdao Qiangsenyuan Technology (QSY), nemakumi emakore avo mumutambo, ichi chikamu chekugadzira goko ndipo panobhadhara ruzivo rwavo rwesangano. Havasi kungogadzira mateko; vari kugadzira nzvimbo inodzorwa yekutadza — mold inofanira kumira 1500°C+ asi yobva yatyoka zvakakwana kubvisa chikamu chakaoma pasina kukuvadza madziro matete. Kune alloys epamusoro-tembiricha senge nickel-based iwo avanonyora, iyo goko rekugadzira inokwenenzverwa kuti irambe kuita kwesimbi. Iyo goko rakajairwa rakatarisana ne superalloy rinowanzo konzera kusvibiswa kwepasi, gritty, fused layer iyo inotyisa kumisa muchina gare gare.
Takamboita mavharuvhu estainless steel uko shinda dzairamba dzichibuda dzakamonyaniswa zvishoma. Mupari wemhosva? Iyo yekupisa yekuwedzera kusawirirana pakati peiyo ceramic musimboti uye goko. Nheyo yacho yaidzora simbi inosimbisa zvekungoiburitsa kunze. Kugadzirisa kwanga kusiri shanduko yeCAD; yakanga ichigadzirisa tembiricha yepre-heat ye mold isati yadururira kushandura gradient yekusimbisa. Ndirwo rudzi rweruzivo rwakadzikama rwaunovaka pamusoro pemakore makumi matatu, rudzi runoparadzanisa kukanda kunoshanda kubva kune kwepamusoro-kutendeseka.
Sarudzo dzeZvinhu: Kupfuura Kungodonha-Pasi Menyu
Vatengi vanotumira zvinhu zvakatemwa-316 isina tsvina-uye funga kuti ndizvozvo. Asi kunyungudika kudzidzira investment casting products yakasiyana nekugadzira kana kuita jecha. Uri kubata nekupisa kudiki, kazhinji vacuum kana argon atmosphere, uye chimiro chezviyo chinoumba zvakasiyana. Kune QSY's renji, kufamba kubva kabhoni simbi kuenda kune cobalt-based alloy haisi nyaya yekuchinjanisa ingots. Iyo fluidity inoshanduka, iyo shrinkage inoshanduka zvakanyanya, uye kupisa kurapwa protocol post-casting inove yakakosha.
Ndinoyeuka muenzaniso wemudziyo wekuvhiya wakagadzirwa kubva kune imwe martensitic isina tsvina. Kudhinda kwaida kuomarara. Isu takarova nhamba yekuoma, asi zvikamu zvaive brittle. Nyaya yaive yekuteedzera zvinhu kubva kune inodzoreredza zvinhu (yakadzokororwa sprue uye vanomhanya) inokanganisa shanduko. Taifanira kuenda kune 100% virgin melt, iyo yakaputika bhajeti asi yakagadzirisa dambudziko. Chiyeuchidzo chekuti zvinhu zviri pachitupa hazvisi nguva dzose zviri muforoma; nzira inotsanangura zvinhu zvekupedzisira.
Apa ndipo apo imba yebasa yakazara inowedzera kukosha. QSY's combo ye Investment casting uye mu-imba CNC machining zvinoreva kuti vanogona kuraira nezve dhizaini tweaks ekugadzira. Zvimwe kuwedzera dhizaini diki hazvigoneke pakuita kwechikamu, asi vanogona kupa zano rakasiyana alloy iro rinoregerera zvakanyanya kana kupisa kurapwa kunowana simba rinodiwa pasina kuita kuti chikamu chisachinjike. Iko kushanda pamwe chete kweinjiniya, kwete kungotenga odha.
Iyo Machining Handoff: Apo Kukandira Kunosangana Nechokwadi
Ino ndiyo nguva yechokwadi. Munozunza muti, moputika goko, uye mocheka masuwo. Iye zvino une mutsara wakagadzirwa. Yekutanga CNC probe hit inokuudza zvese nezve yako maitiro ekutonga. Kuitwa zvakanaka kunopa mukana wemari inofanotaurwa. Ndakaona zvitoro uko dhipatimendi remuchina nevanovamba vari muhondo—vagadziri vemichina vachigunun’una pamusoro penzvimbo dzakaoma uye macores anochinja, vanovamba vachipomera maturusi ehasha.
Mabasa akabatanidzwa anoderedza izvi. Kana zvikwata zvekukanda uye CNC zviri pasi pedenga rimwe, senge pa QSY, mhinduro inokurumidza. Kana homwe ikaramba yakasunga, patani yewakisi inogona kugadziriswa mukudzokorora kunotevera. Vanonzwisisa kuti kukanda hakuna kupera kana yadururwa; inopedzwa kana ichinge yagadzirwa, yakaongororwa chikamu. Kune avo akanyorwa akakosha alloys, ayo anowanzo hutsinye pakushandisa, iyi synergy yakakosha. Iwe unogona kugadzira dhizaini ine zvikamu zvakakora padyo nenzvimbo dzekusungirira kuti urarame kushushikana kwemuchina, chimwe chinhu chemuchina wekutamba wakachena chaisazofunga nezvazvo.
Tsanangudzo inoshanda: datum kumisikidzwa. A yakanaka Investment casting maitiro achasanganisira kugadzira mapatani ewakisi uye mateko ane machinable datum maficha mupfungwa. Aya anogona kunge ari madiki mapedhi akakandwa pane asiri-akakosha nzvimbo, achipa yakachena, yakagadzikana nzvimbo yekutanga setup. Chinhu chidiki chinoderedza zvakanyanya kuoma kwekugadzirisa uye inovandudza kudzokorora. Iyi ndiyo pfungwa-yekupedzisira-yekupedzisira inotsanangura mutengesi wechokwadi weinjiniya investment casting products, kwete chete zvikamu caster.
Kukundikana seChishandiso Chekudzidza (Iyo Inodhura Rudzi)
Hauna kunyatsodzidza Investment casting kusvika warasa mabhechi mashoma anodhura. Pakutanga munguva yangu, takanga tine odha yepombi impellers mune duplex stainless. Zvikamu zvakapfuura X-ray, kuedzwa kwekumanikidza, zvese. Vakakundikana mumunda mushure memwedzi mishomanana kubva mukushungurudzika kuora kwekuputika. Chikonzero chikuru? Incomplete solution annealing mushure mekukanda. Isu takanga tatevera yakajairwa nguva / tembiricha, asi kupatsanurwa kwechikamu mune iyi dhizaini yakagadzira huwandu hwekupisa hwaidzivirira musimboti kusvika pakupisa kwakanyanya. Kugadzirisa kwacho kwaive kutenderera kutenderera kune nguva refu yekunyorova. Zvinyorwa zvemutengi hazvina kutsanangura izvi; zvakanga zviri patiri kuti tizive zvatisingakwanisi kuita.
Imwe yemhando yepamusoro: micro-porosity muzvikamu zvinorema zviri padyo nemadziro matete. Iyo simulation software inogona kusairatidza, asi ruzivo runodaro. Dzimwe nguva mhinduro haina-intuitive, sekushandisa kutonhora muforoma kumanikidza kusimba kwegwara kure nenzvimbo ine dambudziko, kana kutogadzira patsva gating system yekudyisa simbi zvakanyanya. Idzi hadzisi mhinduro dzemabhuku; ndiwo matipi aunovandudza mushure mekuona zana akasiyana geometries achisimba.
Ndiko kukosha kwepodfolio yekambani yenguva refu. Rini QSY vanoti vagara pairi kwemakore makumi matatu, zvinoreva kuti vasangana-uye vakagadzirisa-aya maitiro ekutadza pasimbi yakakandwa, simbi, uye iwo anonyengera alloys. Ruzivo rwavo rwemaitiro iraibhurari yematambudziko apfuura uye yakasimbiswa mhinduro, inova ndiyo inonyanya kukosha asset kana usiri kukanda zvidhinha zviri nyore.
Chiyero Chaiyo: Kuenderana, Kwete Chete Yegoridhe Sample
Chero ani zvake anogona kugadzira imwe yakakwana prototype nenguva yakakwana nemari. Dambudziko remaindasitiri riri kugadzira nhamba ye1001 yakafanana nenhamba nhamba 1. Apa ndipo panouya zvinyorwa zvemaitiro uye kutonga, asiwo apo unyanzvi hunosangana nesainzi. Iko viscosity ye slurry, kona ye dip, kuoma kwemhepo - izvi zvinogona kuenzaniswa, asi zvichiri kuda vashandi vane unyanzvi kuti vatarise uye vagadzirise.
Zvepamusoro-soro investment casting products, kuwirirana uku ndiko kutengesa. Funga nezvemotokari turbocharger dzimba kana mafuta system zvikamu. Kugona kweiyo foundry kunoratidzwa neiyo Cp/Cpk data, yayo yekutanga-pass goho mitengo. Izvo zvishoma nezve kugadzira chikamu chimwe chinokatyamadza uye zvimwe nezve kugadzira zviuru gumi zvinofinha zvakafanana, zvisina hurema. Izvi zvinoda kukura kunowanzouya chete nechiyero uye nguva mukushanda.
Ndichitarisa kune mutengesi, ini ndinogara ndichibvunza nezve maitiro avo ekusimbiswa kwechikamu chitsva. Ivo vanomhanya here statistical process control (SPC) yekudzidza pane yekutanga batch yekugadzira? Vanobata sei kupfeka kwewakisi nekufamba kwenguva? Mhinduro dzinokuudza kana ivo vachifunga kupfuura kurongeka kwekutanga. Chinangwa ndechekubatana kwavanove kuwedzera kwechikwata chako cheinjiniya, vachinyatso gadzirisa hupenyu hweiyo Investment casting tooling uye process. Ipapo ndipo paunobva pakutenga chikamu kuenda kunotenga yakavimbika, inogadzirwa neketani yekugovera.
