Mukamva 'makampani opanga ndalama mumlengalenga', chithunzi chomwe chilipo nthawi zambiri chimakhala chowoneka bwino, chopangidwa ndi makina opangira ma turbine. Imeneyo ndi nthano chabe. Zowona zake ndizambiri, zowoneka bwino, komanso zodzaza ndi zosagwirizana pakati pa mapangidwe abwino ndi ma geometry opangidwa. Sizongopanga mawonekedwe; ndi za kupanga mawonekedwe kuti apulumuke akupanga anayendera, matenthedwe m'zinthu, ndi wopanda mawotchi kupsyinjika, mtanda pambuyo mtanda. Obwera kumene ambiri, ngakhale mainjiniya ena, amapeputsa sayansi yeniyeni yakuthupi ndi kayendetsedwe ka kayendetsedwe kake kamene kakwiriridwa mu nthawi ya 'sera yotayika'.
The Core: Zonse Za Chipolopolo (ndi Kudikirira)
Matsenga enieni, ndi mutu waukulu kwambiri, mkati Azamlengalenga Investment kuponya si sera kapena chitsulo—ndi chigoba cha ceramic. Kupeza chigoba chamitundu yambiri kulondola ndi luso lobisika ngati sayansi. The slurry mamasukidwe akayendedwe, stucco mchenga tinthu kukula kugawa, kuyanika chilengedwe chinyezi ndi kutentha... kusintha kulikonse kusintha komaliza dimensional kulondola ndi pamwamba pamwamba. Ndawonapo mapulojekiti akuchedwa kwa milungu ingapo chifukwa malo okhala m'chipinda cha zipolopolo sanali okhazikika, zomwe zimatsogolera ku ming'alu yaying'ono yomwe imangowonekera pambuyo pothira ndikugwedezeka. Ndi njira yapang'onopang'ono; inu mukumanga chipolopolo, kuumitsa icho, kumanga wosanjikiza wina. Palibe kuthamangira popanda kunyengerera umphumphu.
Apa ndi pomwe makampani omwe ali ndi cholowa chozama, monga Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., kukhala ndi malire ogwirika. Kugwira ntchito kwazaka zopitilira makumi atatu, awona njira zonse zolephera za zipolopolo. Chikumbukiro chokhazikitsidwa patsamba lawo pa tsngtaocnc.com sikungotsatsa. Zimatanthawuza kudziwa, mwachitsanzo, momwe shrinkage yochokera ku nickel-based alloy imayenderana ndi kukula kwamafuta amtundu wawo. Ichi si chidziwitso cha mabuku; idalowetsedwa muzaka makumi angapo zamabuku.
Kusankhidwa kwa zida zodzitchinjiriza za chipolopolo - silika wosakanikirana, zircon, alumina-silicate - zimayendetsedwa ndi alloy yomwe ikuponyedwa. Thirani superalloy mu chipolopolo cholakwika, ndipo mumapeza kusintha kwa mankhwala, kuipitsidwa pamwamba, ndi gawo lomwe liri ngati zidutswa. Ndi masewera ofananira omwe amafunikira maziko kuti akhale ndi phale yotakata, yomwe QSY imatchula za cobalt ndi nickel-based alloys. Simungangodumphira popanga aloyi watsopano; zimafuna kukonzanso dongosolo la zipolopolo, zomwe ndi zodula, ndondomeko yobwerezabwereza.
Kupitilira Kuponya: Kuvina Kosalekanitsidwa ndi CNC Machining
Nayi mfundo yofunika yomwe nthawi zambiri imaphonya: palibe zowulutsa mumlengalenga zomwe zilidi 'zowoneka bwino'. Mawonekedwe aliwonse ovuta - nkhope za flange, mabowo a bawuti, malo osindikizira - amafunikira makina a CNC a post-cast. Zabwino kwambiri makampani opanga ndege zopangira ndalama phatikizani mwayi uwu mosalekeza. Kuponyera kuyenera kupangidwa poganizira ma datums, ndipo mazikowo ayenera kumvetsetsa momwe kupsinjika kotsalira kuchokera pakuponyedwa kumakhudza kusokonekera kwa makina.
Ndikukumbukira pulojekiti yomanga nyumba zopangira makina opangira magetsi pomwe gawo lotayirira lidayendera, koma pakukonza, gawo lokhala ndi mipanda yopyapyala linapotoza mokwanira kuti lichotse gawolo. Nkhani yake? Njira yochotsera zipata ndi chokwera idapangitsa kupsinjika komweko. Yankho lake linachokera ku gulu lokonza makina lomwe likugwira ntchito limodzi ndi akatswiri a metallurgists kuti akonzenso njira yodyetserako. Ichi ndichifukwa chake kampani ngati QSY ikuwonetsa zonse ziwiri kuponya ndalama ndi CNC Machining pansi pa denga limodzi ndi ofunika. Imatseka njira yolumikizirana pakati pa mapangidwe oponya ndi gawo lomaliza lopangidwa ndi makina, kumachepetsa kwambiri mitundu yolephera.
The Machining of cast superalloys ndi chilombo china. Nthawi zambiri amakhala ovuta, okwiya, komanso amakonda kugwira ntchito mowumitsa. Kugwiritsa ntchito njira yolakwika kapena choziziritsira kungayambitse ming'alu yaying'ono pamwamba, ndikupangitsa kuti kamvekedwe ka mawu kukhala vuto. Wothandizira wophatikizidwa amamvetsetsa izi kwathunthu. Amadziwa momwe zinthu zawo zotayira zimakhalira pansi pa makina awo.
Ma Nuances Azinthu: Sizitsulo Zonse Zosapanga dzimbiri Zofanana
Kutchula zitsulo zosapanga dzimbiri ngati zinthu zilibe tanthauzo muzamlengalenga. Kodi tikulankhula za 17-4PH yamphamvu kwambiri? 316L ya kukana dzimbiri? Kapena giredi yamtengo wapatali ya martensitic pagawo linalake lofikira? Iliyonse ili ndi mawonekedwe osiyanasiyana osungunuka, kuthira, ndi kutentha. Mayesero enieni a maziko ali muzitsulo zapadera: zomwe zili ndi nickel monga Inconel 718 kapena 713C, zomwe ndizo zikuluzikulu za zigawo zotentha.
Kuponya izi ndi masewera apamwamba. Ndiokwera mtengo, ali ndi mazenera ocheperako (kutentha kwapakati pa solidus ndi liquidus ndi kolimba), ndipo amafuna chithandizo chokwanira cha kutentha kuti akwaniritse mpweya wofunikira wa gamma. Kupatuka kulikonse pamlingo wozizirira kumatha kusintha mawonekedwe amakanika. Kuthekera kwa foundry kumatsimikiziridwa ndi kugwirizana kwake ndi zida izi pazambiri zothira. Kutchulidwa kwa ma aloyi oterowo ndi kampani ngati QSY kukuwonetsa mwachindunji kuyanjana ndi mapulogalamu ovuta kwambiri, kupitilira magawo amtundu wamba.
Chithandizo cha kutentha ndi njira yaying'ono. Sikuti kuzungulira kwa uvuni; ndi malo oyendetsedwa bwino (nthawi zambiri vacuum kapena argon) kuteteza makutidwe ndi okosijeni pamtunda (makulitsidwe) ndi decarburization. Kufanana kwa ng'anjo, mitengo yazitunda, njira yozimitsa - zonsezi ndizofunikira kwambiri. Kutentha kosakwanira kumatha kuwononga gawo lopangidwa bwino, ndipo zolakwikazo zitha kudziwika pakuyesa kutopa.
The Gating and Feeding Puzzle: Kumene Chiphunzitso Chimakumana Ndi Kuchita
Mapulogalamu a CAD amatha kutsanzira kudzaza nkhungu ndi kulimba, koma dziko lenileni nthawi zonse limawonjezera makwinya. Kupanga makina a gating ndi riser (feeder) ndiye vuto lalikulu la mainjiniya. Cholinga chake ndikukwaniritsa kulimbitsa kolunjika, komwe gawolo limalimba poyamba, kudyetsa kuchokera ku zokwera, kupewa shrinkage porosity. Zimamveka zowongoka, koma ndi mawonekedwe ovuta, okhala ndi mipanda yopyapyala, ndizowopsa.
Nthawi zambiri mumayenera kulolerana. Kuonjezera zokwera kapena zokulirapo kumapangitsa kumveka bwino koma kumawonjezera zokolola zachitsulo (chiŵerengero cha kulemera kwa gawo lomaliza ndi chitsulo chonse chomwe chatsanulidwa), chomwe pazitsulo zokwera mtengo zimawomba bajeti. Zimapanganso malo okhudzana kwambiri kuti achotsedwe pambuyo pake, zomwe zingakhudze pamwamba. Ndakhala ndikuwunikidwa komwe tidadutsamo kambirimbiri kamangidwe ka mageti, kupereka zolemetsa pang'ono kuti zitsimikizike kukhulupirika kwadongosolo. Zokwera zokha ziyenera kupangidwa kuti zikhale zosungunuka motalika kuposa gawolo, zomwe zimaphatikizapo mawerengedwe a modulus (chiwerengero cha volume-to-surface-area ratio).
Ichi ndi chiweruzo choyera, chogwiritsidwa ntchito mwaumisiri. Katswiri wodziwa bwino amatha kuyang'ana pagawo lodutsa ndikudziwa bwino komwe malo otentha angapangire komanso komwe porosity ingabisale. Chigamulochi chimamangidwa pazaka zambiri zodula zitsanzo (kuyesa kowononga) ndikufanizira mawonekedwe amkati ndi zolosera zoyerekeza.
Ubwino ndi Ecosystem, Osati Dipatimenti
Quality control mu Azamlengalenga Investment kuponya si sitepe yomaliza yoyendera; izo zalukidwa mu siteji iliyonse. Zimayamba ndi sera yomwe ikubwera ndi ma certs a ceramic. Ndiye ndi njira yoyendetsera: kuyang'anira kutentha kwa thanki ya slurry, kuyeza makulidwe a chipolopolo pa kuviika kulikonse, kujambula kutentha ndi nthawi. Pambuyo poponya, mumasunthira ku NDT (Mayeso Osawononga): kufufuza kwa fulorosenti (FPI) kwa ming'alu ya pamwamba, ma radiography (X-ray) kwa voids mkati, ndi mochulukira, CT scanning kwa ndime zovuta zamkati.
Mbali yovuta ndi traceability. Chigawo chilichonse, kuchokera ku bulaketi yaying'ono kupita ku chopondera chachikulu, chiyenera kutsatiridwanso ku nambala yake yotentha yosungunuka, chigoba chake chomangira zipolopolo, chothira chake, ndi batchi yake yochizira kutentha. Izi zimapanga deta yochuluka kwambiri. Kulephera m'munda zaka zingapo pambuyo pake kumatanthauza kuti muyenera kuyang'ana mmbuyo ndikuwona ngati mbali zina za zinthu zomwezo kapena batch yokonzekera ili pachiwopsezo. Kuthekera kwa kampani kuyang'anira izi modalirika ndi gawo lalikulu la kudalirika kwake.
Pamapeto pake, chizindikiro cha wothandizira wokhoza sikungopanga chitsanzo chabwino. Ikutumiza mosasinthasintha, kutsatiridwa pamlingo wotheka kupanga, chaka ndi chaka. Ndi za kukhala ndi machitidwe ndi chilango kuti agwire kugwedezeka mu ndondomeko ya ndondomeko asanatulutse mtanda wa zidutswa. Izi ndizomwe mukuyang'ana mukawunika makampani awa - kuya kwadongosolo kuseri kwa gawo lonyezimira.
