Kana vanhu vazhinji vanonzwa 'investment casting foundry,' vanofungidzira musangano une huruva uzere nemapateni ewakisi uye ceramic slurry. Icho chikamu chayo, chokwadi, asi zvakafanana nekutsanangura mota nebasa rayo rekupenda. Iyo chaiyo nyaya iri mukushivirira kutonga, iyo gating system dhizaini iyo isina munhu anoona, uye iyo metallurgical kuenderana kubva pakupisa kusvika pakupisa. Vatengi vakawanda vanouya vachifunga kuti ndezvekuwana 'net shape.' Ini ndinopokana kuti zviri pamusoro pekuwana fungidziro, yakavimbika chimiro, batch mushure mebatch, uko mutengo chaiwo hausi mumutengo weyuniti asi muyero yezvirasha uye yakadzika machining nguva yaunochengeta-kana kusachengeta.
Iyo Shell Game: Haisi Kungopfeka
Iyo nzira yekuvaka goko ndipo panoiswa nheyo, chaizvo. Zvinowanzotarisirwa pasi. Hatisi kungonyika muti wewakisi muslurry uye stucco. Iyo viscosity yejasi rekutanga, hupfu hwezircon, hunyoro hwenzvimbo yekuomesa uye tembiricha - shanduko yega yega inoshandura kupera kwepasi uye kugadzikana kwedimensional. Ndakaona mabhechi uko goko raiita serakakwana asi rakazoratidza kutsemuka kwakanyatso kudhirowewa. Mupari wemhosva? Kumhanyisa kuomesa kutenderera pakati pemajasi. Deko rinoda kufema uye kurapa, kwete kungooma. Kuimhanyisa kunochengetedza zuva asi kunodhura vhiki mukugadzirisa zvakare.
Apa ndipo pane makumi emakore ekushanda, sepa Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), shandura uchiisa muzvarirwo. Unokudziridza kunzwa nezvazvo. Iwe unoziva kuti mwaka wechirimo monsoon muQingdao uchakanganisa sei matangi ane slurry uye gadzirisa magadzirirwo preemptively. Haisi mune chero bhuku rekushandisa; iri mumabhuku ezvinyorwa uye ndangariro dzakabatana dzevatariri vepasi. Kutarisa kwavo kwenguva refu shell mold casting uye Investment casting zvinoreva kuti vakavaka raibhurari yemaparamita emhando dzakasiyana dzejometri uye alloys.
Semuenzaniso, nemidziyo yakatetepa-yakakomberedzwa musimbi isina tsvina, goko rinoda kupenya kwepamusoro kubvumira magasi kubuda panguva yekudira, asiwo simba rakakwana rekuramba simbi static pressure. Chiyero. Kuzviita zvisizvo zvinoreva misruns kana kutsemuka kwegoko. Takambova nepurojekiti ye turbine blade prototype uko kumucheto kwakanyanyisa kupinza. Iyo yakajairwa goko kugadzirwa haina kukwanisa kubata kuvhunduka kwemafuta. Isu taifanira kugadzirisa iyo binder system mumajasi ekutanga, tichiwedzera imwe refractory kuvandudza simba rakasvibira uye kupisa kwekuvhunduka. Zvakatora katatu kudzokororwa kuti uwane ruzha.
Metal Matters: Kupfuura Kungonyunguduka
Kutaura nezve alloys, kusarudzwa uye kubata kwesimbi ndeimwe yakajairika oversimplification. 'Unodira simbi isina tsvina, handiti?' Zvakanaka, hongu, asi 304, 316, 17-4PH, kana tsika duplex? Mumwe nomumwe anoita zvakasiyana mu mold. Iyo superalloys-iyo nickel-based uye cobalt-based alloys QSY rondedzero - mhuka dzakasiyana. Kunyungudika kwavo maitiro, fluidity, uye mabatiro avanoita negoko zvakakosha.
Mhepo yevira ndiyo yakakosha. Kune akawanda epamusoro-anoshanda alloys, haugone kungonyungudika mumhepo yakashama. Isu tinoshandisa vacuum kana inodzorwa mumhepo kunyungudika kudzivirira oxidation uye kutora-kunhonga kwetsvina. Musiyano wemichina yezvivakwa pakati peyakanyatso chengetedzwa kunyunguduka uye zvishoma oxidized imwe inogona kuve yakakosha, kunyanya kune zvikamu zveaerospace kana zvekurapa zvikumbiro. Iyo inodhura mutyairi, asi isinga taurike kune spec basa.
Kudurura tembiricha imwe danidzo yekutonga. Kunyanya kupisa, uye unoisa panjodzi yekukukurwa kwemukati meganda kumeso, zvichitungamira mukukanganisa kusanganisa. Kunyanya kutonhorera, uye simbi inogona kusazadza zvikamu zvitete. With simbi yakakandwa, une graphitization yekufunga nezvayo. Hapana tembiricha 'yakakwana' yepasirese; ndiwo uwandu hwaunodzikisira pasi zvichibva pane chikamu chejometri uye nekupisa chaiko kweiyo alloy yauri kushandisa zuva iroro. Iwe unodzidza kuverenga pamusoro pesimbi mune ladle.
Iyo CNC Handshake: Iko Kukandira Kunosangana Nechokwadi
Iyi ipfungwa yakakosha kune vakawanda vakamira Investment casting foundries miss: handoff kune machining. Kana iyo yekukanda isina kugadzirwa uine machining mupfungwa, uri kungopfuura matambudziko kuzasi. Dimensional consistency ndiyo inonyanya kukosha. Nheyo yakanaka haingobudisi kugadzirwa; inopa kukanda kunogara kwakadzikama muCNC vise, ine inofanotaurwa yemvumo yemasheya.
Ndosaka iyo yakasanganiswa modhi panzvimbo yakaita seQSY inoita zvine musoro. Vanobata zvose zviri zviviri Investment casting uye CNC machining. Iyo yemhinduro loop yakasimba. Kana machinists ari kugara achirwa kuti awane datum poindi nekuti mabhegi ekumisikidza haaenderani, ruzivo irworwo rwunodzokera kuchitoro chemaitiro uye mainjiniya ekugadzira. Pamwe majekiseni ewakisi anoda kugadziridzwa, kana nzvimbo dzekugadzirisa pamuti wewakisi dzinoda kugadzirwa patsva.
Isu takabatanidza yakazara 5-axis machining centre yekupedzisa turbine zvikamu. Mabheti mashoma ekutanga akaburitsa kuti yedu se-yakakandwa nzvimbo pane dzimwe dzakaomarara nzira dzemukati dzaive dzakaomarara kuti probe iwane kuverenga kwakachena. Taifanira kudzokera kunonatsa bhachi redu rekutanga bhachi slurry, tichishandisa yakakwenenzverwa-giredhi refractory kuvandudza kupedzisa kwe'se-cast' munzvimbo idzodzo, kungopa CNC mukana wekurwa. Yakawedzera nhanho kumaitiro edu, asi yakadzikisa machining nguva uye kutadza kwekuongorora neinosvika makumi matatu%.
Kukundikana seData Point
Iwe haudzidze zvakawanda kubva pakurongeka kwakakwana. Iwo akafoira mabasa ndiwo mabhuku. Ndinorangarira imba hombe yepombi mu duplex simbi isina tsvina. Yakapfuura NDT yese, yaitaridzika zvakanaka. Asi panguva yekuyedzwa kwehydro-panzvimbo yemutengi, yakadonha paflange. Chikonzero chacho? Micro-shrinkage porosity pamwe nenzvimbo inopisa yatakanga tisina kudya zvakakwana. Yedu yekunyepedzera software yanga yairatidza seine njodzi yakaderera, asi isu tainge takafuratira iyo alloy chaiyo yekusimba maitiro. Isu takazvigadzirisa kwete nekungowedzera simbi (iyo inowedzera mutengo uye huremu), asi nekugadzirisazve wax cluster kutaridzika uye kushandisa exothermic padding pagoko riri munzvimbo iyoyo.
Imwe yemhando yepamusoro 'chiitiko chekudzidza' kukanganisa. Marefu, akatetepa anogona kutenderera panguva yekutonhodza kana asina kunyatsotsigirwa muchoto. Takambova nenhevedzano yenjanji dzekutungamira dzakabuda nehuta hushoma. Mushonga wacho wakanga usiri mukudirwa; kwaiva mukututira kwatakaita matemhe aipfurwa mugomba rekutonhodza. Takatanga kushandisa maseta eceramic kuti tivatsigire pamwe nehurefu hwavo panguva yakaoma yekutonhora. Nyore, asi yakagadzirisa nyaya.
Aya haasi matambudziko edzidziso. Ndiwo mapikicha ezuva nezuva ayo muvambi ane nhoroondo yakadzika yekushanda, senge makumi matatu emakore ekumashure QSY mareferensi, anounganidza mhinduro dze. Icho hwaro hweruzivo hunokanganisa zvakananga kuvimbika uye nguva yekutungamira.
Chiyero Chaicho: Kuenderana Kwenguva
Saka, chii chinotsanangura anokwanisa Investment casting foundry? Haisi iyo yevira inoyevedza kana nyowani 3D wax printer. Iko kugona kumhanya Jobho A-105 nhasi wozoimhanyisa zvakare mwedzi mitanhatu kubva zvino nemhedzisiro yakafanana. Iri nezve kudzora kwemaitiro ayo anopona nekuchinja kwevashandi uye kusiyanisa kwezvinhu batch.
Izvi zvinoda masisitimu akarangwa: kuomarara wax process control, yakachengetedzwa slurry zvivakwa, yakanyorwa kupfura macurves, uye akadzama melt matanda. Basa rinofinha, rine hunyanzvi. Asi ndizvo zvinobvumira foundry kufamba kupfuura prototyping mukugadzira. Iwe unogona kuona iyi yakatarisana nekugona kwakasimba munzira iyo kambani inoda QSY inozviratidza-inoratidza kuvapo kwenguva refu kweindasitiri uye huwandu hwezvinhu hunotaura kune ruzivo rwakaunganidzirwa kwete kungoita runyorwa rwemidziyo.
Pakupedzisira, kukosha kuri mukuva shamwari inofanotaurwa. Injiniya inogadzira chikamu inofanirwa kuziva kuti simba rekusimba padhirowa richave riripo muchikamu. Maneja wekutenga anofanirwa kuziva mutengo uye kuendesa kubva kune yechishanu odha ichaenderana neyekutanga. Kuvimbika uku hakuna kuvakwa muboardroom, asi pauriri hwekutanga, kuburikidza nemaitiro anodzorwa uye kudzidza kutonga pane zvese kubva kuhukobvu hwegoko kusvika pakumhanya kwekudira. Ndiwo musimboti wemhizha, kure kure nemufananidzo uri nyore wewakisi nemoto.
