Paunonzwa 'kurasika kukanda wakisi masevhisi,' pfungwa zhinji dzinosvetukira kune zvishongo zvakaoma kunzwisisa kana zvidimbu zveunyanzvi. Ndiwo mufananidzo wakajairika, asi munharaunda yeindasitiri, chikara chakasiyana zvachose. Izvo zvishoma nezve yakapfava filigree uye zvimwe nezve kugadzira yakakwirira-kutendeseka, yakaoma zvikamu izvo kazhinji hazvigone kugadzirwa chero imwe nzira. Hunyanzvi chaihwo hausi mukunyungudusa simbi chete; zviri mukutonga cheni yese-kubva pakudzikama kwepateni yewakisi kusvika pakupinda kwegoko uye kupisa kwekupedzisira kurapwa. Vatengi vazhinji vanouya vachifunga kuti zviri nyore kutsiva machining, asi kushivirira kurongedza kubva wakisi kuenda kusimbi inyaya pachayo.
Iyo Core yeMaitirwo: Izvo Zvese mune Details
Ngatitaure wakisi. Haasi ese majekiseni wax anogadzirwa akaenzana. Kune blade yeturbine, unoda musanganiswa une pedyo-zero shrinkage uye kusimba kwepamusoro kubata iwo ma profiles emhepo. Kumuviri wevharuvhu, wakisi yakawanda inoshanda. Sarudzo pano inoraira zvese zviri pasi pasi. Ndakaona mapurojekiti achienda kudivi nekuti wakisi yakasarudzwa pamutengo chete, zvichiita kuti goko ritsemuke panguva yedewax kana kupera kwesimbi kusingagamuchirwe. Icho chisarudzo chekutanga chisingatarisirwi nevakawanda.
Chikamu chekuvaka goko ndiko uko hunyanzvi hunosangana nesainzi. Haisi kungonyudza uye kuisa stuccoing. Iyo slurry viscosity, hunyoro hwenzvimbo yekuomesa uye tembiricha, saizi yezviyo zvestucco uye kugovera - imwe neimwe dhizaini inodzorwa shanduko. Deko rakanyanya kutetepa rinogona kutsemuka panguva yekudira; yakanyanya kukora, uye inogona kutadzisa gasi kubuda, zvichikonzera porosity. Isu takambove nebatch yepombi impeller uko iwo mafeni ekuomesa aive asina kurongeka, achigadzira humidity gradient. Zvakaguma nei? Shells aitaridzika akakwana asi aive nesimba risingaenderane, zvichitungamira kune 30% chirairo rate. Kugadzirisa kwacho kwaive kwechinyakare asi kwakakosha: kudzokorodza kudzora kwezvakatipoteredza uye kuita mamwe macheki kakawanda.
Ipapo kunouya kutsva uye kudira. Apa ndipo panoitika 'rasika wakisi' zvechokwadi. Kutenderera kwechoto kunofanirwa kubvisa zvachose wakisi pasina kutsemura ganda receramic. Kunyanya kukurumidza, uye kuvhunduka kwekushisa kunokuvadza. Kudururira pachayo, kunyanya kune alloys senge nickel-based kana cobalt-based superalloys, idhanzi chaiyo yekushisa nekumhanya. Hausi kungozadza mold; uri kudzora kusimba kuti uderedze kupatsanurwa uye kubvarura kupisa.
Zvinhu Zvekushandisa: Haisi Simbi chete
Iyi ipfungwa huru yekusiyanisa. Chitoro chinoti chinobata simbi isina tsvina chinogona kunge chakanakira 304 kana 316. Asi paunopinda munzvimbo ye duplex simbi isina tsvina, kana kunaya-kuomesa mamakisi se17-4PH, iyo yese nzira inoda kugadziriswa. Iyo gating system dhizaini, tembiricha yekudurura, iyo post-casting kupisa kurapwa-zvese zvakanangana neiyo alloy's metallurgy.
Basa redu pa Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kazhinji inosanganisira aya alloys anokosha. Neanopfuura makumi matatu emakore ekukanda uye machining, iwe unoona mapatani. Semuenzaniso, necobalt-based alloys, iyo inowanzoshandiswa pakupfeka zvakanyanya uye kupisa-kupisa kwekushandisa, iyo fluidity yakaderera. Izvi zvinoda magedhi akakura, ane rupo uye zvikwiriso kuti tive nechokwadi chekudyisa uye kudzivirira kukanganisa-kumhanya. Iyo chiyero - yakawandisa yakawandisa zvinhu inokwidza machining mutengo gare gare, asi yakawandisa njodzi chikamu chakakanganisika. Iko kufona kwekutonga kwakavakirwa pane chikamu geometry nguva imwe neimwe.
Matanho emashure ekukanda akanyanya kukosha. Kune nickel-based alloy component yakanangana neaerospace, kupisa kwekupisa kutenderera hakugone kutaurirana uye kunofanirwa kurongeka. Haisi fungidziro; zvakakosha pakuwana izvo zvakatsanangurwa zvemakanika. Apa ndipo panowanikwa zvivakwa zvakabatanidzwa, seizvo zvatinazvo kuQSY, zvinoratidza kukosha kwavo. Kudzora muitiro kubva pateni kuenda kumichina chikamu pasi pedenga rimwe kunoderedza zvinoshanduka uye kuzvidavirira mapundu.
CNC Machining: Iyo Inodiwa Partner yekukanda
Ichi ndicho chokwadi: kwete Investment casting inobuda yakagadzirira kuiswa. Kune nguva dzose masuwo ekubvisa mapoinzi, nzvimbo dzinoda kushivirira chaiko, uye maficha ekubatanidza anoda machining. Iyo synergy pakati pekukanda uye CNC madhipatimendi yakakosha. Injiniya yekukandira inofanirwa kugadzira chikamu ichi nekugona mundangariro-kusiya stock yakakwana, kudzivirira dzakadzika, dzakatetepa homwe isingagoni kusvika nemudziyo, uye kuisa mitsara yekuparadzanisa zvine mufungo.
Takadzidza izvi kuburikidza nekukakavadzana. Pakutanga, taikanda yakanaka, yakaoma yakawanda, chete kuti timu yekugadzira itambure nekuisunga pasina kukanganisa, kana kuwana chisimbiso chakakosha chaive munzvimbo ine micro-porosity. Iye zvino, nzira yacho ndeyekubatana. Chikwata chekugadzira chinoongorora magadzirirwo ekukanda kumberi. Vanogona kukumbira imwe datum pad yakakandwa pane chikamu chete chekugadzirisa, icho chinozogadziriswa. Iyi mhando ye-cross-functional tweaking ndiyo inoparadzanisa chikamu chinoshanda kubva kune yakakwirira-yakavimbika.
Visiting the QSY nzvimbo, unoona kuyerera uku. Castings inofamba kubva pakuzunza kuenda kune yekutanga kugaya, yozoenda kune CNC zviteshi kwavanogadzirwa zvichibva pane imwechete yedhijitari modhi inoshandiswa kugadzira chishandiso. Inovhara loop. Kune vatengi, kunyanya avo vari muzvikamu zvakaita sesimba kana muchina unorema, kubatanidzwa uku kunoreva imwe nzvimbo yekubatana uye mutoro wechikamu chakapedzwa, inova mukana wakakura.
Zvakajairwa Pitfalls uye Mutengi Kusanzwisisana
Iyo hombe ndiyo tarisiro ye-as-cast surface kupera. Apo shell mold casting uye kukanda kwekudyara kunopa kupedzisa kwakanaka kana kuchienzaniswa nekukanda jecha, ichiri nzvimbo yakakandwa. Ichava nechimiro chechimiro. Kana iwe uchida girazi rinopera, iro rinobva kupost-cast polishing kana machining. Kuve akajeka pamusoro peizvi kumberi kunochengetedza zvakawanda kumashure-uye-mberi gare gare.
Imwe inguva yekufambisa. Kukandwa wakisi kwakanaka hakusi kukurumidza. Kugadzira maturusi ewakisi ega zvinogona kutora mavhiki. Ipapo iwe une chivakwa chegoko, inova mazuva mazhinji, akawanda-layer process. Vatengi vanoda prototypes mukumhanya dzimwe nguva vanosundira mapfupi, sekushandisa 3D-akadhindwa mapatani zvakananga. Izvi zvinogona kushanda kune imwe-yega yekuona modhi, asi kune inoshanda simbi chikamu, yakadhindwa yekutsva maitiro akasiyana uye anogona kukanganisa goko. Ingozi. Isu takatendeseka pamusoro peiyo trade-off.
Mamiriro emitengo haanzwisisike zvakare. Mutengo wepamusoro hausi kunyanya musimbi yakasvibirira; iri mukushanda kwakasimba, nhanho-inofambiswa nemaitiro ekugadzira patani, shelling, uye chaiyo hunyanzvi inodiwa. Kune maumbirwo akareruka muhuwandu hwepamusoro, mamwe maitiro akachipa. Kukosha kwewakisi yakarasika kuri mukuoma, kushanduka kwe alloy, uye net-shape kana pedyo-net-shape kugadzirwa kunoderedza basa rechipiri.
Kutarisa kune Real-World Application
Tora chikamu chatakagadzira nguva pfupi yadarika: imba ye hydraulic control system mumidziyo yekumahombekombe. Chikamu chacho chaive nemachanera emukati aipindirana, maflange ekunze anokwira, uye aifanirwa kunge ari muduplex simbi isina ngura yekuramba kuita ngura. Kuigadzira kubva pakasimba kungadai kwakave kutyisa kwezvinhu zvakaraswa uye zvigadziriso zvakaoma. Forging yanga isiri sarudzo nekuda kweiyo yemukati geometry.
Kurasika wakisi yaive nzira yakajeka. Dambudziko raive rekuona kuti nzira dzemukati dzakachena dzeceramic shell yakasara uye kuwana iyo inodiwa yekumanikidza kutendeseka. Mhinduro yacho yaisanganisira kungwarira gedhi kugadzira yakananga kusimba, yakatarwa goko rekugadzira kuitira nyore kugogodza, uye yakaoma leaching maitiro mushure mekuzunza. Zvadaro, timu yeCNC yakagadzira maflange uye tambo dzechiteshi. Kubatanidzwa kwacho kwaive kwakakosha — timu yekukanda yaiziva kuti inzvimbo dzipi dzaizogadzirwa, saka vaigona kusiya imwe stock paidiwa.
Ichi ndicho chokwadi chezuva nezuva. Hazvina kunaka. Ndezvekugadzirisa matambudziko madiki, akabatana-wax shrinkage pano, kusimba kwegoko ipapo, kupisa kupisa paramita yeiyi alloy. Iyo sevhisi haisi yekungopa yekukanda; ndezvekupa chinhu chinoshanda, chakavimbika. Izvo zvinoda kunzwisisa kwakadzama, kunoshanda kweketani yese, kubva mukamuri yewakisi kuenda kuchigayo cheCNC. Ndizvo zvinotsanangura munhu anogona kurasika basa rekukanda wakisi munyika yemaindasitiri. Ndiwo musiyano pakati pekugadzira chimiro nekugadzira chikamu chinoshanda.
