Kana vanhu vazhinji vachinzwa kukanda mari, vanofunga nezve yakakwirira-yekupedzisira ceramic shell process. Asi mumigero, kune yakakura chunk yezvikamu zveindasitiri, ndiyo girazi remvura kukanda nzira iri kuita kusimudza zvinorema. Yakachipa, inokurumidza kune mamwe majometri, uye kutaura chokwadi, kuregerera zvakanyanya munzvimbo yechitoro. Chinhu chikuru chandiinacho ndechekuti vanhu vanochiramba semhando yakaderera zvachose. Handiwo mufananidzo uzere. Hunhu hwayo hunoenderana zvachose nehunyanzvi hweiyo foundry uye zvinodiwa zvekushandisa. Kune miviri yakawanda yevharuvhu, mapombi epombi, kana mabhuraketi emuchina, zvinopfuura zvakakwana uye nzira inodhura zvakanyanya.
Iyo Core Yekuita: Sodium Silicate uye Jecha
Zita rinopa: girazi remvura kukanda inoshandisa sodium silicate, iyo viscous, glue-like binder, yakasanganiswa nejecha refractory kugadzira mold. Idanho rematanho maviri ekuomesa. Kutanga, unoridza CO2 kuburikidza neforoma kuti uiise pekutanga-ndiko kukurumidza kubata. Zvadaro, iwe unowanzo tevera nekupisa kwemvura kunopisa kupisa hunyoro hwasara uye kuwedzera simba remuumbi. Apa ndipo panoonekwa gomba rekutanga. Kana iwe ukamhanyisa kupera mvura mumuviri kana kuita kuti tembiricha iite zvisizvo, mold inogona kuchengetedza yatinoti yasara simba nyaya, zvichitungamira kune veining kana kudonha panguva yekudira. Ndakaona zvichiitika nemacomplex cores.
Iyo pateni midziyo inowanzova aluminium kana resin. Iyo yekumusoro kupedzisa haikwikwidze ceramic goko, asi neyakatsetseka-giredhi yakatarisana nejecha, unogona kuwana inoremekedzwa Ra kukosha. Kubatsira chaiko kuri mukupinza kwe mold. Nekuda kwekuti tsanga dzejecha dzakasungirirwa pane kuputirwa, mold inofema zvirinani panguva yekudururwa, ichideredza kukanganiswa kwegasi. Iyi ndiyo godsend ye compact, chunky simbi castings uko gasi kusungwa ihondo inogara iripo.
Kwazvinonetsa kune zvikamu zvitete zvakanyanyisa kana zvakadzama zvakadzama. Iyo jecha mold haigone kudzokorora kuvimbika kweceramic slurry. Saka, kana mutengi akauya nechikamu chakafukidzwa nemavara akanaka kana reza-mutete zvimbi, ndinovatungamira vakananga kune ceramic shell process nguva dzese. Asi kune yakasimba giya imba kana yemugungwa inokwana? Mvura yegirazi yekukanda ndiyo nzira yekutanga yandinofunga.
Material Compatibility uye Real-World Limits
Isu tinomhanyisa zvese kubva kabhoni simbi kusvika kune duplex isina tsvina kuburikidza neyedu girazi remvura kukanda mitsetse. Maitiro acho anoshamisa zvakasiyana-siyana-huchenjeri hwezvinhu. Kubata kune zvinhu zvakakwirira-alloy, semamwe nickel-based mamakisi. Iyo mold yemakemikari nharaunda panguva yekudira dzimwe nguva inogona kutungamira kune yakaoma-kupfuura-yakajairwa pamusoro chiyero, iyo inodya mune machining nguva gare gare. Iko kutengeserana. Kune yakajairwa 304 kana 316 isina tsvina, kashoma kuve nyaya.
Imwe yemusoro chaiyo yandinorangarira yaive nebatch yemapombi casings muCF8M. Iwo ma castings akabuda aine zvakasarudzika, localized rough texture. Mushure mekutonga kunze kwesimbi tembiricha uye kumhanya kudira, isu takaitsvaga ichidzokera kumusanganiswa wejecha. Kugovanisa saizi yejecha resilica kwaive kwakadzimwa, uye iyo sodium silicate ratio yaive yakakwira zvakanyanya kune iyo chaiyo geometry, zvichikonzera kuita kushoma pane iyo simbi-mold interface. A tweak kumusanganiswa wejecha uye kudzikiswa kwebhinder percent kwakaribvisa ipapo. Ndidzo dzakajeka, maoko-pagadziridzo ausina kumboverenga nezvazvo mumabhuku ezvinyorwa.
Apa ndipo pane chiitiko chemuvambi pane zvese. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakore avo makumi matatu ekukandira uye kugadzira, vaizova neraibhurari yakadzama yeizvi mabikirwo ezvishandiso zvakasiyana uye zvikamu zvemaumbirwo. Irwo ruzivo rwemasangano ndirwo runoparadzanisa basa-shopu kubva kune akavimbika mutengesi. Ivo vaizoziva, semuenzaniso, kuti kune yavo hunyanzvi cobalt-based alloys, chaiyo pre-heat tembiricha ye girazi remvura kukanda mold is non-negotiable kudzivirira kutsemuka.
The Machining Handshake
Izvi zvakakosha uye kazhinji zvinotaurika zvisina kunaka. A girazi remvura kukanda ichava nemvumo yakakora uye nzvimbo yakasiyana-siyana pane kunyatsoita mari yekukanda. Ndizvo zvakapiwa. Iyo synergy pakati peiyo foundry uye shopu yemuchina inoda kusimba. Iyo inowanikwa inofanirwa kunzwisisa kuti yakakosha machining datum mapoinzi ari kupi uye kuona kuti nzvimbo idzi dzakakandwa zvakachena sezvinobvira. Sezvineiwo, machinist anofanirwa kunzwisisa iyo yekukanda ingangoita shrinkage uye zvinogona kuoma nzvimbo.
QSY modhi yekupa yakabatanidzwa shell mold casting, kukanda mari, uye CNC machining pasi pedenga remba yakangwara. Inobvisa munwe-kunongedza. Ivo vanogona kudzora maitiro ekukanda vaine yekupedzisira machining mupfungwa, vachiwedzera stock chaiyo painodiwa uye nekuideredza kumwe kunhu. Kune girazi remvura rakakandwa valve muviri, vanogona kusiya ane rupo 3mm pazviso zveflange asi 1.5mm chete pamadziro asina-akakosha emukati, achigadzirisa zvese goho rekukanda uye machining mutengo.
Ndakabata nevatengesi vakaparadzana, uye misoro ndeyechokwadi. Mugadziri wemuchina anopomera muvambi wenzvimbo yakaoma iri kutsenga maturusi; the foundry inopomera zvinhu. Kana chiri chinhu chimwe chete, vanogadzirisa dambudziko. Vanogona kugadzirisa kutonhora kwekukanda kana kusarudza giredhi rakasiyana rejecha repakati kuvandudza machinability. Uku kusanganisa kukosha kukuru-yekuwedzera kune chero mutengi.
Economic Reality uye Nguva Yekuisarudza
Ngatitaurei nhamba. Yepakati-kusvika-yakakwirira vhoriyamu inomhanya (taura, mazana mashanu kusvika ku5,000 zvidimbu) zvezvikamu zvinorema pakati pe1kg ne50kg, girazi remvura kukanda inenge nguva dzose sarudzo ine mari yakawanda. Mutengo wepateni wakaderera pane weceramic shell, uye mutengo weyuniti unodonha zvakanyanya nehuwandu. Iyo yekupwanya-chero poindi nekukanda jecha inogona kuve yakaoma; kune zvimiro zviri nyore, kukanda jecha kunogona kuhwina. Asi kune chero chinhu chinoda chimiro chemukati chemukati kana kuomarara kuri pakati nepakati, kugona kwegirazi remvura kugadzira imwe-chidimbu chepakati musangano kunopa muganho.
Kukundikana kukuru kwandakaona nekuita uku kwaisava kwehunyanzvi, asi kuronga. Mutengi aisimbirira kuishandisa kune chikamu chaive chikuru, chakafuratira chine maburi ane shinda. Chikamu chakamonyana kunge chipu chembatatisi panguva yekutonhorwa. Yakanga isiri iyo maitiro eiyo geometry. Taifanira kunge takasundidzira kumashure tikakurudzira ndiro yakagadzirwa kana jecha rakapfava rine anneal yekuzorodza. Chidzidzo chakadzidzwa: usaedze kumanikidza mbambo ine sikweya mugomba rakatenderedzwa, zvisinei nekuti buri racho rinoita serinodhura zvakadii.
Saka, unozvitsanangura rinhi? Funga nezvezvikamu zviri kushanda kutanga, aesthetic yechipiri. Funga ma hydraulic manifolds, maturusi ekurima, mafuremu ekugadzira chikafu, uye mhando yezvigadzirwa zvemaindasitiri izvo QSY ingangogadzira matani. Ndeyezvikamu zvinogara mukati memuchina, zvichifukidzwa negirizi uye kutora mitoro, kwete kugara pasherufu yekuratidzira.
Ramangwana: Niche asi Kutsungirira
Haisi nzira inoyevedza. Hazvizoshandiswe kune aerospace turbine blades kana mishonga yekurapa. Asi kune yakakura nzvimbo yeindasitiri yakajairika, girazi remvura kukanda ari pano kugara. Chinangwa chekusimudzira chinoratidzika kunge chiri pakunatsa mabinder masisitimu-kuita kuti awedzere kushamwaridzana nemamiriro ekunze uye kugadzirisa shakeout zvivakwa kuitira kuti jecha riputse zviri nyore mushure mekukanda, kuvandudza mitengo yekudzorera.
Kune mugadziri, kiyi ndeye kuziva miganhu uye masimba ayo zvakanyanya uye kuataura akavimbika kune vatengi. Izvo ndezvekumisa tarisiro chaiyo yekupedzisa kwepamusoro, kushivirira kwedimensional (kazhinji CT8-CT10 paISO 8062), uye machining zvinodiwa. Mumaoko echigadzirwa chekare, chinogadzira zvinhu zvakavimbika, zvinogara kwenguva refu zvinoita kuti michina yenyika irambe ichichinja. Iro gamba risingaimbidzwe renyika yekukanda, uye kuiramba iko kukanganisa kwakazvarwa nekusaziva. Unoshanda nayo kwenguva yakareba zvakakwana, unokudziridza ruremekedzo nokuda kwehunhu hwayo hwakakasharara, hwakavimbika.
