Ngativei vakatendeseka, apo vanhu vazhinji vanonzwa 'kurasika kukanda wakisi,' vanofungidzira mhizha inoshamisira ichidurura sirivha yakanyungudutswa mufovhoro yepurasita nokuda kwechishongo. Izvo hazvina kukanganisa, asi idiki, ingangoita yerudo kona yeizvo maitiro aya ari munyika yeindasitiri. Izwi racho pacharo, kurasika wakisi simbi kukanda, kana kuti kunyanya kuisa mari, kazhinji kunorerutswa. Dambudziko chairo harisi kungonyungudusa simbi uye kurasikirwa nenamo; ndezvekutonga cheni yose-kubva patani yekutanga yewakisi kusvika pakurapa kupisa kwekupedzisira-kuwana kushivirira uye kuvimbika kwezvinhu izvo mamwe maitiro asingagoni kubata. Ndiko uko unyanzvi hunosangana nesimbi isingaregereri.
Wakisi ingori Mavambo, uye Iri Kurwadza Musoro
Wese munhu anotarisisa pamusoro pesimbi, asi iyo wakisi pateni ndipo paunohwina kana kurasikirwa nebasa. Iyo jekiseni paramita yewakisi-tembiricha, kudzvanywa, nguva yekugara-vanoraira zvese. Kupisa zvakanyanya, uye wakisi inodzikira zvisingaite, zvichikonzera warpage inongoonekwa mushure mekunge wavaka ganda receramic. Kunyanya kutonhora, uye iwe unowana kushomeka kwepamusoro kudzokororwa, pamwe kunyange kuyerera mitsara. Ndakaona zvitoro, zvakanaka, zvimedu zvimedu zvese nekuti ivo havana kuverengera hunyoro hwemhepo hunokanganisa maitiro ewakisi zuva riya. Chinhu chipenyu, kutaura chokwadi.
Zvino moita gungano kuita miti yenamo. Iri ibasa remaoko, rine unyanzvi. Hausi kungonamira zvikamu; uri kugadzira gedhi system. The sprue, runners, uye ingate anofanirwa kugadzirwa kubvumira simbi kuzadza mold zvachose uye negwara kusimba kuti kuderedze shrinkage porosity. Ita izvi zvisizvo, uye iwe unenge uine yakanaka, dimensionally akakwana akakandwa ane hurema hwemukati hunotadza pasi pekushushikana. Ndinoyeuka purojekiti yepombi impeller mu duplex simbi isina tsvina apo taifanira kuisa patsva magedhi katatu kuti tibvise nzvimbo inopisa yairamba ichikonzera micro-fissures.
Chinhanho ichi ndipo panodaidzira chiitiko chemuvambi. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), nemakumi matatu emakore emutambo, vaizove neizvi pasi kune sainzi. Iwe haugone kunyengedza iyo mhando yemaitiro memory. Iri muminwe yevashandi vari kuunganidza miti, vachinyatsoziva kuti ingani wakisi yekushandisa chisimbiso pasina kugadzira bhurobhu rinoparadza kuvharwa kwegoko gare gare. Kutarisa kwavo kwenguva refu Investment casting zvinoreva kuti vangangoona chero wakisi yekutadza modhi yaungafungidzira.
Kuvaka Shell: Ganda reCeramic, Layer by Layer
Iyo nzira yekugadzira goko inonyengedza iri nyore pamapepa: nyura muti wewakisi muceramic slurry, stucco nejecha, rega iome, dzokorora. Asi dhiyabhorosi ari mune zvakadzama. Iyo slurry viscosity inofanirwa kuongororwa nguva dzose-inoshanduka nekushisa uye sezvo zvinhu zvinoputika. Bhachi rekutanga, jasi rechiso, ndiro rinonyanya kukosha. Inoshandisa iyo yekupedzisira-yakatsetseka zircon hupfu kana chimwe chinhu chakafanana kutora yega yega yega. Kana jasi iri rikasvibiswa kana rikashandiswa zvisina kuenzana, nzvimbo yekupedzisira yekukanda inova negomba kana kushata, zvisinei nezvauchaita gare gare.
Zvikamu zvinotevera zvinowedzera simba. Iwe unofamba kubva kune yakanaka stucco kuenda kune yakakora zvinhu. Nzvimbo yekuomesa yakakosha; nekukurumidza uye goko rinotsemuka kubva mukushushikana kwemukati, kunonoka uye unoisa panjodzi yekukura kweforoma kana kudonha. Mumamiriro okunze ane hunyoro, iyi ihondo inogara iripo. Taigara tichishandisa dehumidifiers 24/7 mumakamuri ekuomesa munguva yemwaka wemonsoon. Mutsara wega wega unofanirwa kuoma zvachose usati wanyura inotevera, zvikasadaro, unoteya mwando unoshanduka kuita chipfunga panguva yekudonha uye unotsemura goko kubva mukati kunze. Ndakaputika goko rese mu autoclave — inoshamisa, inodhura nyonga nyonga — nekuti takamhanyisa kuomeswa kwechitatu.
Iyo yekupedzisira goko gobvu inhare yekutonga. Iko kusimba kune mahombe ekukandira, asi zvakare zvinoreva zvimwe zvinhu zvekupisa, zvichikanganisa kutonhora kwesimbi. Kune zvinhu zvakatetepa-madziro, unoda goko rakasimba zvakakwana kuti ribate simba resimbi asi risiri rakakura rinokonzera kutonhora. Ndiwo chiyero chaunodzidza kubva kune akaparara mabhechi.
Dewaxing uye Kupfura: Pfungwa Yekusadzoka
Ichi ndicho chikamu chakarasika. Iwe haugone kudzosa wakisi. Iyo nzira mbiri huru ndeye autoclave (steam) uye flash fire. Autoclave yakapfava pagoko, ichishandisa high-pressure steam kunyungudusa nekufuridzira wakisi kunze. Asi iwe unofanirwa kunhonga wakisi - inodzokororwa, uye kune yakakwira-vhoriyamu shopu, iyo yakakosha mari yekuchengetedza. Kupfurwa nemwenje ndizvo chete: kubatisa goko muchoto kupisa wakisi kunze. Inokurumidza, asi kuvhunduka kwekushisa kunogona kutsemura makanda asina simba, uye unorasikirwa newakisi.
Mushure mekuita dewaxing, iwe unosara uine hollow ceramic mold. Inoratidzika kunge isina kusimba, asi haisati yadzingwa. Iyo yekupfura nhanho, inosvika 1000 ° C, inonyura zvidimbu zveceramic pamwe chete, zvichigadzira mold yakasimba, yakagadzikana yekemikari yakagadzirira simbi. Kupisa uku kunopisa chero zvisaririra zvewakisi uye mwando. Iyo mold inofanira kudirwa ichiri kupisa, kazhinji kubva kunze kwechoto. Kudira muforoma inotonhora kunokonzeresa kusimba kusati kwasvika uye kusamhanya. Kurongeka kuri pano kutamba—kuwiriranisa choto ichinyungudusa simbi nechoto ichipfutidza mondo.
Kudira uye Zvinouya Pashure
Kudururwa kunonzwa kunge kwapera, asi kwapera mumasekonzi. Kune alloys senge nickel-based kana cobalt-based superalloys-zvinhu QSY inonyora sechinhu chakakosha - mamiriro ekunze akakosha. Kazhinji, izvi zvinoitwa pasi pevacuum kana mune inodzivirira argon atmosphere kudzivirira oxidation. Uri kubata nesimbi dzinenge dziine hunyanzvi pakudurura tembiricha. Kudonha kudiki muvacuum system kunogona kukanganisa kupisa kwezvinhu zvakakosha zviuru.
Wobva wamirira. Goko rinofanirwa kutonhora pasi usati warityora. Iyi chiyero chekutonhora chikamu chekurapa kwekupisa kune mamwe maalloys. Kana kuchinge kwatonhora, unotyora goko nesando, matafura anozunguzika, kana kunyange majeti emvura anodzvanya. Chasara muti wesimbi, zvidhori zvako zvakavigwa mutsvina yemasuwo nevamhanyi. Maitiro ekugogodza anofanirwa kuve ane hukasha kuti abvise ceramic asi kwete zvehasha zvinokuvadza zvikamu zvitete zvekukanda.
Inotevera ndeye kucheka. Kubvisa zvikamu kubva pamuti kunowanzoitwa neabrasive masaha kana ikozvino, kazhinji, CNC mabhandi ekunyatso. Wobva waenda kukuya, kuputika kwejecha, uye kupedza. Apa ndipo panowanikwa mukana wepedyo-net-shape kurasika wakisi simbi kukanda inobhadhara chaizvo. Kana iwe wakaita zvese nemazvo, pane shoma yakawedzera stock yekubvisa. Asi kana pateni yako kana goko rakanga radzimwa, machinist anokuzivisa iwe - nenzwi guru.
Nei Zvichiri Zvichikosha Munyika yeCNC
Nemazuva ano 5-axis CNC machining achigona kudaro, vanhu vanobvunza kuti sei uchinetsekera nekukanganisa, nhanho dzakawanda dzekukanda maitiro. Kune imwechete-kure prototypes, ivo vakarurama-ingoigadzira. Asi kune vhoriyamu, kune yakaoma yemukati geometries (funga turbine mablades ane emukati kutonhora chiteshi), kana kune zvimwe zvimiro zvemukati, kukanda hakurondwe. Inobvumira kuyerera kwezviyo kunotevera chikamu contour, iyo inogona kuwedzera kuneta hupenyu. Iyo inowanzo shanda-inoshanda kune yakaoma zvimiro pane machining kubva kune yakasimba block.
Uye kune zvikamu zvinozoona kurongeka machining, senge akawanda ezvikamu zvinouya kubva kune yakazara-sevhisi mupi seQSY (saiti yavo. https://www.tsingtaocnc.com inosimbisa kukanda kwavo kwakasanganiswa uye CNC machining kugona), zvine musoro wakakwana. Iwe unokanda kuti utore iyo yakakosha, yakaoma fomu ine yakanaka zvinhu zvivakwa, wobva wagadzira yakakosha mating nzvimbo uye maburi kune yakasimba kushivirira. Inzira yakasanganiswa iyo inokwirisa masimba epasirese.
Iko kukosha kwechokwadi kwechivako hakusi mumidziyo chete; iri muruzivo rwakaunganidzirwa rwekubatanidza dhizaini nechakakodzera zvinhu uye maitiro. Paunoona kambani yave nemakore makumi matatu, senge intro ye Iyo kambani Qingdao Qiangsenyuan Technology Co., Ltd. zvinoratidza, havasi kungotengesa macastings. Vari kutengesa mutongo kuti vadzivise hunza dzinonyudza purojekiti - rudzi rwekutonga rwunouya chete kubva pakugadzika mabhomba akawanda akatyoka uye kuongorora akawanda akaremara microstructures. Ndizvo zvauri kunyanya kutenga nemunhu akura Investment casting shamwari.
