Vanhu vazhinji pavanonzwa 'stainless steel investment casting', vanofananidzira chinhu chisina kukanganisa, chinopenya kubva mubhurocha. Chokwadi, kugaya kwezuva nezuva kwekuita kuti ishande, yakanyanya messier uye inonakidza. Haisi yekungonyungudusa simbi nekuidira muforoma yakanaka; inhaurirano yenguva dzose pakati pemaitiro enyama, geometry, uye mutengo, uko 0.5mm madziro emadziro sarudzo inogona kuita kana kuputsa chirongwa. Ndakaona akawanda madhizaini achipinda akanakira machining asi hope dzekukandira, ndipo ndipo panotanga hurukuro chaiyo.
Iyo Shell Game: Zvese zviri muMold
Goko ndizvo zvese. Ndicho chinhu chokutanga chaunodzidza. Tiri kutaura nezve ceramic shell mold yakavakirwa kutenderedza wakisi patani. Nhamba yejasi, slurry viscosity, stucco sand grit-nhanho imwe neimwe inoshanduka. Ita zvisizvo, uye uchaona hurema hwakaita senge simbi inopinda, apo simbi inopinda mukati megoko, ichisiya nzvimbo yakakasharara, yakasanganiswa iyo inotyisa kuchenesa. Ndinorangarira batch ye316L mavharuvhu miviri yatakamhanya; zvinyorwa zvekutanga zvakabuda negritty texture pandima dzomukati. Mupari wemhosva? Iyo yekutanga slurry layer yaive yakanyanya kutetepa, uye iyo yakanaka stucco jecha haina kugadzira yakakwana yemhinganidzo. Isu takagadzirisa nguva yekunyura uye tikachinjira kune jecha rakaomarara rezircon rejasi rekutanga rekuchengetedza. Dambudziko rakagadziriswa, asi zvakatitorera svondo.
Apa ndipo panoratidza chiitiko chemuvambi. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), nemakumi emakore avo vari mumutambo, iyi nzira yakadanwa mukati. Vanogona kunge vaona yega yega kukundikana kwegoko maitiro aungafungidzira. Haasi mashiripiti; idatabase yekutadza uye kugadzirisa kwakavakirwa pamusoro pemakore makumi matatu. Iwe haugone kumhanyisa nguva yekuomesa pakati pejasi, zvisinei kuti chirongwa chekugadzira chinoti chii. Humidity inova muvengi wako kana shamwari yako.
Uye wakisi haisi namo chete. Iyo jekiseni paramita yeiyo yekutanga pateni-kumanikidza, tembiricha-inobata kugadzikana kwayo kwedimensional. Wakisi yakamonyoroka zvishoma inoshandura yakananga mugoko rakamonyoroka receramic, uyezve kupinda muchikamu chakakandwa icho chisisaonekwe. Tinopedza nguva yakawanda tichikodzera nzira yewakisi sezvatinoita kudira simbi. Ndiyo hwaro husina kunaka, hwakakosha.
Material Haisi Ingori Chete Chete
Kutsanangura CF8M kana 17-4 PH ingori pistol yekutanga. Kunyunguduka ndiko kunoitika simbi. Pakudyara kwekudyara, uri kubata nekupisa kudiki, saka kutonga kwakakosha. Deoxidation tsika nealuminium kana silicon? Iyo inoshandura iyo fluidity uye yekupedzisira kusanganisa zvemukati. Kune zvikamu zvine dzvinyiriro, uhwu hupenyu kana rufu.
Tora 17-4 PH simbi isina tsvina. Iyo yakakurumbira yekunaya-kuomesa giredhi. Iyo yekudyara yekukanda mukana ndeyekuti iwe unogona kuwana yakanakisa se-yakakandwa pamusoro pekupedzisira uye yakaoma maumbirwo. Asi iyo H900 mamiriro ekupisa kurapwa? Kana mhinduro annealing isina kuitwa zvakakwana zvakafanana, iwe unowana zvisingaenderane mechanical zvivakwa. Ndakaona makuponi ekuedza kubva kune imwechete yekukanda batch inoratidza 50 ksi yakapararira musimba regoho nekuti mutoro wechoto hauna kurongeka. Chikamu chacho chairatidzika zvakanaka, asi chingadai chakakundikana mubasa.
Iyi ndiyo imwe nzvimbo uko kubatana nenyanzvi kunobhadhara. A foundry anoitawo mumba CNC machining, seQSY, ine mukana mukuru. Ivo vanonzwisisa kuti iyo yekukanda iyo microstructure uye inogona micro-porosity ichabatana sei nekucheka chishandiso. Ivo vanogona kugadzirisa kupisa kwekupisa kuti kukwidziridza machinability pasina kupira zvivakwa zvekupedzisira, chimwe chinhu chakamira chekukanda imba chingasafunge. Ndiyo maonero akazara ehupenyu hwechikamu.
Geometry: Rusununguko uye Musungo
Ehe, kukanda kwekudyara kunopa iwe unoshamisa rusununguko rwejometri. Mavara emukati, pasi, macurves akaoma-zvose zvinogoneka. Asi 'zvinogoneka' hazvirevi 'zviri nyore' kana kuti 'zvinodhura'. Mutemo wechigumwe ndiwo mukobvu wemadziro. Asi munyika chaiyo, zvikamu zvinoda mbabvu, maboss, uye mapedhi anokwirisa. Chinetso ndechekugadzirisa kusiyana kwehuremu.
Kukundikana kwechinyakare ndiko shrinkage porosity munzvimbo inopisa. Fungidzira imba yevharuvhu ine gobvu flange ichienda kune muviri mutete. Chikamu chakatetepa chinotanga kuoma, chichiisa parutivi gobvu flange, icho chinozodzikira apo chinotonhorerwa pasina chitubu chesimbi yekuchidyisa. Zvakaguma nei? Nzvimbo ine sponji, isina simba chaipo paunoda simba. Kugadzirisa? Strategic kushandisa kutonhora (simbi inoiswa mugoko kuburitsa kupisa) kana wakisi padding kugadzira humwe huremu hunozogadziriswa gare gare. Ipikicha.
Ndakashanda papombi impeller kamwe chete, ose matete, aerofoil mashizha. Dambudziko rakanga risiri mashizha; yakanga iri nzvimbo yepakati. Yakanga yakakura zvikuru maererano nemashizha. Isu takazopedzisira nekuwedzera ceramic musimboti kuhubhu kuti iite buri, kudzikisa huwandu hwekupisa uye kugadzira imwe yunifomu yekutonhora mamiriro. Shanduko yekugadzira yakafambiswa nemaitiro ekukanda, kwete imwe nzira yakapoteredza. Ndizvo zvinobudirira Investment casting.
Iyo Finish Line haimbofi Ingori Nhanho Imwe
Knock-off, cut-off, grinding, shot blasting, heat treatment, pickling... post-casting steps ndiko uko mutengo uye kunaka kunogona kusiyana zvakanyanya. Wese munhu anoda yakagadzirira-ye-kuisa-chikamu, asi iyo yakagadzirira ine maseru.
Kudimbura inyanzvi. Kubvisa gating system (matanho anodyisa simbi muchikamu) pasina kukuvadza chikamu. Kushandisa mavhiri abrasive kunogadzira kupisa, izvo zvinogona kukanganisa simbi munzvimbo yakakanganiswa nekupisa, kunyanya pamagiredhi akaomarara. Dzimwe nzvimbo dzakaomarara dzinoshandisa bhendi masaha kana kunyange CNC machining kubvisa magedhi nemazvo. Iyo yakasara yegedhi ipapo inoda kugadzika pasi. Iri ibasa remaoko, rine unyanzvi. Hunhu hwekupedzisa uku hunokanganisa zvakananga hupenyu hwekuneta kana gedhi riri munzvimbo yekushushikana kwakanyanya.
Pickling, iyo asidhi yekugezera kubvisa chiyero uye kudzoreredza passive chromium oxide layer pane simbi isina tsvina pamusoro, nderimwe danho rinokosha. Nguva, tembiricha, acid concentration - zvese zvinofanirwa kudzorwa. Pamusoro-pickle, uye iwe unowana yakatemerwa, ine gomba pamusoro. Pasi-pickle, uye unosiya chiyero chakamisikidzwa chinogona kutanga kuora. Ikemikari yekuenzanisa makemikari isingatarisirwe zvakakwana kusvikira chimwe chinhu chabuda chakasviba kana kuti ngura-chakataridzika kubva mubhavhu.
Nei Mudiwa Akakodzera Asingangove Mutengesi
Iri harisi bhizinesi rekutengesa. Iwe hausi kutenga zvigadziriso zvepasherufu. Iwe uri kutenga kugona kwekuita uye kudzika kwekugadzirisa matambudziko. Paunotarisa kumashure kwekambani, sekuona izvozvo QSY yanga ichishanda kweanopfuura makore makumi matatu mukukanda uye kugadzira, inokuudza kuti vakafamba-famba izvi zvekutengesa kwezvizvarwa zveinjiniya. Vanogona kunge vakachengetedza mapurojekiti nekupa zano rekuchinja kwekona kushoma kana imwe alloy giredhi inokanda zvirinani nezvinhu zvakafanana.
Iko kukosha kukuru kune yakanaka foundry inopa kupindira kwekugadzira kwekutanga. Pamberi pemuenzaniso weCAD wapedzwa, chigadziro chisati chatemwa. Ndopavanogona kuti, Tinogona kukanda izvo, asi kana iwe ukatitendera kuti tiwedzere nharaunda iyi zvishoma, tinovimbisa kuti hapana shrinkage, kana Funga nezve nickel-based alloy pano panzvimbo; zvinoramba izvo zvinoparadza nharaunda zviri nani uye isu tine yakasimbiswa goko resipi yayo. Kudyidzana uku kunoshandura kudhirowa kuita chinhu chinogadzirwa, chakavimbika.
Pakupedzisira, kubudirira Stainless simbi yekukandira mari ndeyekugamuchira zvimhingamipinyi zvehurongwa kuti uvhure kugona kwayo. Inhaurirano pakati pechinangwa chekugadzira uye chokwadi chemuviri. Iyo inopenya, yakaoma chikamu padhesiki reinjiniya mugumisiro wezana, zvisarudzo zviduku, zvakarurama - uye zvikanganiso zvishomanana zvakagadziriswa - zvakaitwa munheyo, kare kare simbi isati yambodururwa. Ndizvo zvauri kunyanya kuisa mari mazviri.
