Anthu ambiri akamva 'zigawo zotayira phula zotayika' amafanizira zitsulo zopanda chilema, zonyezimira za turbine kapena zidutswa zaluso. Ndiwo gloss yotsatsa. Zowona pa maziko oyambira ndi nkhani yovuta kwambiri ya ceramic slurry viscosity, kufalikira kwamafuta osagwirizana, komanso kulimbana kosalekeza ndi zophatikizika. Maganizo olakwika kwambiri? Kuti ndi njira imodzi-yokwanira-yonse yolondola. Si. Kulekerera komwe mungagwire pa chida chaching'ono chopanda chitsulo chosapanga dzimbiri ndi dziko lotalikirana ndi zomwe zingatheke ndi nyumba yayikulu ya nickel-based alloy pump, ngakhale kugwiritsa ntchito mfundo zomwezo. kutaya sera mfundo. Mdierekezi ali kwathunthu mwatsatanetsatane zomwe samayika mu kabukuka.
The Core Illusion: As-Cast Finish
Makasitomala nthawi zambiri amapempha kumaliziridwa, poganiza kuti zimapulumutsa mtengo. Zomwe amatanthawuza nthawi zambiri ndikuti safuna makina. Koma m'machitidwe, kwenikweni ngati-cast pamwamba kuchokera ku kuponya ndalama Ntchitoyi ikufunikabe kuyeretsedwa - kudula zipata, kupeta zitsa. Chofunikira kwambiri, mawonekedwe apamwamba amadalira kwathunthu chovala choyambirira cha chipolopolo cha ceramic. Pashopu yathu, takhala zaka zambiri tikuyimba chiŵerengero cha ufa wa zircon/silica binder ndi malo oyanikapo. Mofulumira kwambiri, mumapeza ming'alu yaying'ono; chonyowa kwambiri, chipolopolocho chimakhala chofooka. Ndikukumbukira gulu la matupi a valve pomwe chipolopolocho chinkawoneka bwino, koma nditatha kutulutsa phula ndi kuwombera, ming'alu ya tsitsi inawonekera. Wolakwa? Kutentha kosadziwika bwino kwa usiku kutsika panthawi yovuta kwambiri yowumitsa malaya. Ziwalozo sizinaphwasulidwe, koma zimafunikira kukonza zowotcherera kwambiri, kunyalanyaza phindu lililonse.
Izi zimalumikizana mwachindunji ndi kusankha kwazinthu. Anthu amatchula 316 zosapanga dzimbiri pa chilichonse chowononga. Koma za zida zoponyera phula zotayika zomwe zimadutsa panjinga yotentha, monga zida zotulutsa mpweya, mawonekedwe a 316 amatha kukhala ndi mpweya wa sigma pamalire ambewu, zomwe zimapangitsa kuti zisawonongeke. Nthawi zambiri timalangiza makasitomala kuti aganizire giredi yosinthidwa yokhala ndi kukhazikika kwamafuta. Ndikambirano kakang'ono kamene kamadutsa njira yopangira zitsulo.
Apa ndi pamene zokumana nazo za foundry zimawerengedwa. Kampani ngati Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yomwe ili ndi zaka makumi atatu akuponya ndi kupanga makina, yawona njira zolephera izi. Kuyang'ana kwawo pazinthu monga cobalt ndi ma aloyi opangidwa ndi faifi akuwonetsa kuti amalimbana ndi kupsinjika kwakukulu komwe machitidwewa amapangidwira kapena kusweka. Simungathe kunamizira chidziwitso chochuluka chotere, nthawi zina chowawa.
Kulondola Ndi Ulendo, Osati Chitsimikizo
Mawu akuti precision investment casting amapangidwa mosasamala. Kulondola kwenikweni ndi mndandanda wa masitepe, iliyonse ikubweretsa zolakwika zomwe zingatheke. Jakisoni wamtundu wa sera ndiye ulalo woyamba wofunikira. Tinaphunzira izi movutikira ndi zovuta zambiri. Chitsanzo cha CAD chinali changwiro. Zida za aluminiyamu zinali zolondola. Koma panthawi ya jekeseni wa sera, sitinawerengere kusiyana kwa kusiyana pakati pa zigawo zokhuthala ndi zoonda, zomwe zimatsogolera ku tsamba la nkhondo lomwe linayamba kuonekera pambuyo pomangidwa chipolopolo cha ceramic. Chotsatira? Zida zoponyera zomwe zinali zosawoneka bwino, osati kuchokera kuzitsulo zotsanuliridwa, koma kuchokera pamapangidwe oyambirira a sera. Linali phunziro lochepetsetsa lomwe linatikakamiza kuti tipange zochepetsera pang'onopang'ono mu kapangidwe ka zida kutengera mtundu wa sera womwe timagwiritsa ntchito, zomwe mumangophunzira pakulephera mobwerezabwereza, kokwera mtengo.
Ichi ndichifukwa chake kuphatikiza kwa makina a CNC, monga momwe amaperekera ogulitsa ophatikizika ngati QSY, ndikofunikira kwambiri. Kuponyedwa kumakufikitsani 95% pamenepo, nthawi zambiri ndi malo ovuta omwe amasiyidwa ngati katundu. Kutsirizitsa kwa CNC kumatsimikizira miyeso yomaliza ndikusindikiza kukhulupirika kwapamwamba. Pampando wa valavu wothamanga kwambiri kapena mawonekedwe a mizu ya tsamba la turbine, sitepeyo yopangira makina siwosankha; ndi pamene gawolo limakhala logwira ntchito. Kuyesera kukwaniritsa izi mwachindunji kuchokera ku nkhungu ndi njira yachitsiru pazinthu zambiri zaumisiri.
Chinthu chinanso chomwe chimanyalanyazidwa nthawi zambiri ndi gating ndi kukwera kwa ma alloys osiyanasiyana. Kuponyera zitsulo kumafuna njira yodyetsera yosiyana ndi ya faifi tambala chifukwa cha kusiyana kwa kulimba ndi kakhalidwe kakuchepa. Ndawonapo zojambula zokopera kuchokera kugawo lachitsulo kupita ku gawo la monel zomwe zidapangitsa kuti mizere yapakati ichepe kwambiri. The chipolopolo nkhungu kuponyera ndondomeko imapereka tanthauzo labwino kwambiri, koma sililipira uinjiniya wosalimba. Mufunika gulu lomwe limamvetsetsa momwe zinthu zilili mu nkhungu, osati momwe mungapangire nkhungu yokha.
The Alloy Gambit: Pamene Njira Zapadera Zovuta
Kugwira ntchito ndi ma alloys apadera monga cobalt kapena nickel-based ndi komwe kuponya ndalama zimawala, komanso pomwe zimakhala zovuta kwambiri. Zida zimenezi nthawi zambiri zimatchulidwa kuti zikhale zovuta kwambiri - kutentha kwakukulu, dzimbiri, kuvala. Njira yoponyera iyenera kuteteza katundu wawo. Vuto lodziwika bwino ndi kuipitsidwa panthawi yosungunuka ndi kuthira. Ngakhale kachulukidwe kazinthu zina kungasinthe kwambiri magwiridwe antchito. Timasunga ng'anjo zodzipatulira zamabanja apadera a alloy kuti tipewe kuipitsidwa. Ndi mchitidwe wofuna ndalama zambiri, koma osakambirana.
Chithandizo cha kutentha pambuyo poponya ndi malo ena opangira migodi. Kwa ambiri mwa ma alloys awa, as-cast microstructure si ntchito yaying'ono. Kuchiza njira, kukalamba, HIPping (Hot Isostatic Pressing) -njirazi zimafunikira kuti pakhale mphamvu yolimba yofunikira kapena kukana kukwawa. Nsomba? Angathenso kusokoneza kapena kukweza pamwamba. Tidakhala ndi magawo angapo a Inconel omwe adakumana ndi macheke amtundu uliwonse atatha kuponya koma adasokonekera mopitilira kupulumutsidwa panthawi yamankhwala. Kukonzekera kumaphatikizapo kupanga ma setter a ceramic kuti azithandizira magawo panthawi ya ng'anjo, yankho lomwe linabadwa chifukwa cholephera. Mulingo wothetsera mavuto uwu ndi womwe umalekanitsa wogulitsa magawo ndi mnzake weniweni wopanga.
Izi zimagwirizana ndi kuthekera komwe kumaperekedwa ndi wogulitsa ngati QSY. Kulemba mndandanda wa aloyi enieniwo si mndandanda chabe; ndi chiganizo cha zomangamanga zoyendetsedwa. Aliyense akhoza kusungunula chitsulo chosapanga dzimbiri. Kugwira ma aloyi opangidwa ndi faifi tambala nthawi zonse kumafuna kuwongolera kosiyanasiyana ndi kuwongolera bwino, kuyambira zopakapaka zolipiritsa mpaka kuwunika komaliza.
Kuphatikiza Kofunikira: Kuponya Sichilumba
Palibe gawo lomwe limakhala ngati kuyimba chabe. Imafunika ulusi, mabowo a bawuti, malo osindikizira, nthawi zambiri kuti azitha kupirira kwambiri. Apa ndipamene chitsanzo chakale chotumizira makina opangira makina chimagwera. Malo ofotokozera amasokonekera, kulumikizana kumabweretsa kuchedwa. Kukhala ndi makina a CNC m'nyumba, pansi pa ambulera yamtundu womwewo, ndi mwayi waukulu. Zimalola kuti pakhale ndondomeko yogwirizana: kuponyedwa kungathe kupangidwa ndi makina opangira makina, ndipo ma datum ovuta amatha kuponyedwa mkati kuti ayeretsedwe pa CNC.
Ndikuganiza za chopopera chopopera chomwe timapanga. Kujambula kumatipatsa ife zovuta za vane geometry. Koma chobowola, chisindikizo chakumaso, ndi fungulo zonse ndizopangidwa ndi CNC. Pochita zonsezi, titha kutsimikizira kukhazikika pakati pa mavane otayira ndi ma bore opangidwa ndi makina - chinthu chofunikira kwambiri pakuchita bwino komanso kuchita bwino. Kuyesera kukwaniritsa izi potumiza kuponya kosaphika kwa munthu wina kungakhale vuto lalikulu.
Uwu ndiye mtengo wothandiza wa ntchito yophatikizika molunjika. Sizokhudza kuphweka kokha; ndi za kusunga cholinga cha mapangidwe kudzera muzopanga zonse. Kwa zida zopangira injiniya, izi zimachepetsa chiopsezo kwambiri. Mukuchita ndi gawo limodzi laudindo pa geometry yonse, kuchokera ku kutaya sera ku gawo lomaliza lopangidwa ndi makina.
Kutsiliza: Ndi Luso, Lobisika ngati Njira
Kotero, pamene mukuyang'ana zida zoponyera phula zotayika, simukugula kwenikweni njira yopangira. Mukugula kuti mudziwe zambiri. Mukugula chidziwitso cha guluu la sera lomwe limagwira ntchito bwino pamakoma oonda, kuweruza momwe mungayendetsere gawo mumtengo kuti muchepetse porosity, chidziwitso cha momwe kutentha kwa ng'anjo kumakhudzira gawo linalake. Ndi luso.
Mawebusayiti, monga tsngtaocnc.com a QSY, alemba zomwe angathe: nkhungu ya zipolopolo, kuponya ndalama, CNC, ma aloyi osiyanasiyana. Koma chomwe chikuyimira ndi zaka 30 zothetsa mavuto osasangalatsa omwe amasintha lingaliro kukhala gawo lodalirika, logwira ntchito. Chogulitsa chenicheni sichimangokhala gawo lachitsulo; ndi kupanga zisankho komwe kunalepheretsa zinthu khumi zomwe zikanalakwika kuti zichitike. Ndi zomwe mukufufuza. Zina zonse ndi zitsulo basi.
