Wina akamanena kuti 'kuyika ndalama kwapamwamba', malingaliro ambiri amalumphira molunjika ku manambala olekerera ndi zomaliza zapamtunda. Ndilo gawo lake, zedi, koma ngati mwakhalapo nthawi yeniyeni pamalo oyambira, mukudziwa kuti ndipamene kukambirana kumayambira, osatha. Ubwino weniweni uli m'njira zomwe mumasankha nthawi yayitali chitsulo chisanagunde, zisankho zomwe sizimatengedwa nthawi zonse pamawu amtundu wa PDF. Ndi kamangidwe ka zitseko komwe mumasinthira kutengera zidutswa za mwezi watha, nthawi yowumitsa zipolopolo zomwe mumasinthira kuti mukhale chinyezi chapafupi sabata imeneyo, kapena kudziwa kuti ndi kalasi iti yosapanga dzimbiri yomwe imagwira ntchito pozizira kwambiri pazigawo zokhala ndi mipanda yopyapyala. Ogula ambiri, ndipo moona mtima mainjiniya ena atsopano, amawaona ngati ntchito yamtengo wapatali—tumizani chitsanzo cha 3D, pezani gawo. Kusiyana pakati pa izo ndi zapamwamba kwenikweni ndi pamene chirichonse chosangalatsa, ndi chokhumudwitsa, chimachitika.
Maziko: Zimayambira Sera Isanayambe
Inu simungakhoze kulankhula khalidwe popanda kulankhula za chitsanzo. Ndawona ntchito zikulephera chifukwa sitepe iyi idathamangitsidwa. Chitsanzo changwiro cha CAD sichimangomasulira ku ndondomeko yabwino ya sera. Magawo a jakisoni-kutentha, kupanikizika, nthawi yozungulira-ayenera kuyimbidwa kuti agwirizane ndi sera komanso geometry ya gawolo. Tsamba la turbine lovutirapo lokhala ndi timiyala tating'onoting'ono ta mpweya komanso gawo la mizu yokhuthala? Mudzafunika zipata zosiyanasiyana za jakisoni ndi zokhazikitsira zoziziritsa kumadera osiyanasiyana akufa komweko. Ngati ndondomeko ya sera ili ndi kupsyinjika kwamkati kapena kupotoza pang'ono, izo zimaphikidwa mu sitepe iliyonse yotsatira. Ndimakumbukira ntchito yopangira chopopera chopopera pomwe tinkangokhalira kugunda pang'ono pomaliza. Tidathamangitsa michira yathu pakuwombera kwamasiku ambiri tisanabwerere ndipo tidazindikira kuti kutentha kwa jekeseni kunali 5 digiri C kwambiri, kupangitsa kuchepa kofanana. Ndiwo mtundu wa kukumba chifukwa chomwe chimatanthawuza khalidwe.
Apa ndi pamene zochitika ndi zipangizo sizingakambirane. Pamalo ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi mbiri yawo ya zaka 30, chidziwitso cha sitolo yamtunduwu ndi chokhazikika. Sikuti amangokanikizira sera; iwo akuyembekezera momwe sera a nickel-based alloy gawo la turbine limachita mosiyana ndi sera pagawo lopanda banga la 316 pakuwotcha. Kuoneratu zam'tsogolo kumeneko ndi gawo lachete koma lofunikira mkulu khalidwe kuponya ndalama.
Ndipo kusonkhanitsa sera, kapena mtengo, ndi luso lamakono. Momwe mumayendera pamapangidwe apakati pa sprue zimakhudza mwachindunji kudzaza mphamvu ndi kulimba. Mukufuna kuchepetsa chipwirikiti ndikuwonetsetsa kukhazikika kolowera ku feeder. Zimawoneka zosavuta - kungowotcherera timitengo ta sera - koma ngodya ndi kuyika kwake ndi dala. Mtengo wosakonzedwa bwino ndi njira yopangira matumba ang'onoang'ono ang'onoang'ono, mosasamala kanthu kuti chipolopolo chanu ndichabwino chotani.
Chipolopolo: Kumene Kusasinthasintha kuli Mfumu
Chigoba cha ceramic ndi nkhungu yeniyeni, ndipo kukhulupirika kwake ndi chirichonse. Njira yamitundu yambiri yoviika imawoneka yowongoka: prime slurry, stucco, youma, kubwereza. Koma mdierekezi ali mu tsatanetsatane wa chikwi. Kukhuthala kwa slurry kumafunika kuyang'anitsitsa nthawi zonse ndikusintha - kumasintha ndi kutentha komanso pamene zinthu zimatuluka. Mchenga wa stucco wa kukula kwa njere pa chovala chilichonse (kawirikawiri chowoneka bwino pa malaya akumaso, owoneka ngati malaya osungira) ayenera kuwongoleredwa kuti apange mphamvu ndikulola kuti mpweya ukhale wokwanira.
Malo oyanikapo ndikusintha kwakukulu komwe nthawi zambiri sikumaganiziridwa. Ndagwirapo ntchito m'malo omwe kutentha kwanyengo kumasokoneza ndondomeko zowumitsa zipolopolo, zomwe zimapangitsa kuti pakhale ming'alu kapena kutsika kobiriwira. Chipinda chowumira choyendetsedwa bwino, chokhala ndi kutentha kosasinthasintha ndi kuchotsera chinyezi, sichosangalatsa; ndi maziko ake mkulu khalidwe kuponya ndalama. Popanda izo, mukutchova njuga. Chigobacho chimayenera kukhala champhamvu kuti chisasunthike ndikuchigwira, koma chokhala ndi porous kuti mpweya utuluke panthawi yothira. Kuchita bwino ndi luso lochita kugwiriridwa, ndipo akatswiri amadziwa ndi kamvekedwe ka chigoba chikakonzeka.
Dewaxing palokha ndi chinthu chodabwitsa kwambiri. Ambiri amagwiritsa ntchito steam autoclave tsopano. Kutentha kofulumira kumasungunula sera, koma ngati kuchitidwa mwaukali, kumatha kuswa chipolopolo chifukwa cha kupsinjika kwa kutentha. Kupanikizika ndi nthawi yozungulira imapangidwa zaka zambiri. Mng'alu apa ukhoza kukhala wocheperako, koma umawoneka ngati chipsepse kapena kung'anima pomaliza komaliza, kumafuna ntchito yomaliza yomaliza kapena kupangitsa kukanidwa.
Kusungunuka & Kutsanulira: Mfundo Yosabwerera
Apa ndi pamene ntchito zonse zokonzekera zimayesedwa. Kwa ma alloys apamwamba kwambiri ngati ma aloyi opangidwa ndi cobalt kapena zitsulo zosapanga dzimbiri zosapanga dzimbiri zomwe QSY imalemba, kusungunula ndikofunikira. Sikuti amangofikira kutentha kwa liquidus. Ndi za kugwira nthawi, kuwongolera kwa slag, ndikuchotsa mpweya moyenera kuti muchepetse porosity. Mufunika mpweya wabwino wa ng'anjo (nthawi zambiri argon kapena vacuum ya ma alloys reactive) kuti muteteze makutidwe ndi okosijeni ndi kuphatikizika.
Kuthira ndi mphindi yayifupi, yotsimikizika. Chitsulocho chiyenera kukhala chokwanira kwambiri - chotentha mokwanira kudzaza nkhungu yonse, makamaka zigawo zoonda, koma osati zotentha kwambiri zomwe zimapangitsa kuti zipolopolo zachitsulo ziwonongeke kapena kukula kwambewu. Kuthira kuyenera kukhala kosalala komanso kosalekeza kuti pasakhale chipwirikiti chomwe chingatseke mpweya. Ndimakumbukira nkhani ina yomwe inali ndi zovuta zambiri zomwe tinali ndi porosity mosalekeza pamphambano inayake. Tinayesa kusintha gating, chipolopolo, chirichonse. Pomaliza, tidachepetsa kutsanulira ndi pafupifupi 20%. Zinapezeka kuti kutsanulira mwachangu kunali kupanga vortex m'bowolo, kuyamwa mpweya. Kuyenda pang'onopang'ono, kosasunthika kunathetsa. Nthawi zina kukonza si mkulu-chatekinoloje; ndi kuyang'anitsitsa kokha ndi chipiriro.
Solidification ndiye gawo lomaliza la ntchito yoponya. Kapangidwe ka nkhungu (zipata ndi zodyetsa zomwe tidamanga maola kapena masiku m'mbuyomu) tsopano ziyenera kugwira ntchito. Chitsulocho chiyenera kulimba molunjika, kuchokera kutali kwambiri kubwerera ku chodyetsa, chomwe chimakhala ngati nkhokwe yazitsulo zamadzimadzi kuti zidyetsedwe. Ngati izi sizichitika, mumapeza shrinkage porosity mkati mwa khoma loponyera. Kuyerekeza kwamakompyuta kumathandizira masiku ano, koma palibe chomwe chingalowe m'malo mwa kudula gawo loyamba kuti zitsimikizire mawonekedwe olimba. Ndi mayeso owononga, koma ndi njira yokhayo yotsimikizira kuti ndondomeko yanu ndi yomveka.
Kumaliza & Kutsimikizira: Ntchito Yosawoneka
Mukangogwedeza kutulutsa, mettle yeniyeni ya foundry ikuwonetsa. A mkulu khalidwe kuponya ndalama kuyenera kufunikira kumaliza kochepa. Koma zochepa ndizofunikira. Zolumikizira zipata ndi zodyetsa ziyenera kudulidwa, nthawi zambiri ndi macheka othamanga kwambiri kapena gudumu lopumira. Ndiye pali akupera, kusakaniza, ndi kuwombera kuwombera. Luso apa ndikuchotsa zinthu zochulukirapo popanda kuwononga gawolo kapena kusiya kupsinjika. Kwa bulaketi yofunikira yazamlengalenga, kugaya mwamphamvu kumatha kupanga malo oyambira ma micro-crack.
Apa ndipamene kusakanikirana ndi CNC makina zimakhala mwayi waukulu, china chake QSY's kuphatikiza kuponyera ndi makina khwekhwe mfundo zazikulu. Kukhala ndi makina opangira m'nyumba kumatanthauza kuti gulu lomaliza limamvetsetsa zomwe zili zofunika kwambiri pakukonza pambuyo pake. Akhoza kusiya katundu wowonjezera (kulekerera kwabwino) m'malo omwewo pomwe akuyeretsa malo omwe si ofunikira kuti awoneke bwino. Ndi njira yolumikizirana yomwe imalepheretsa kugaya mopitilira muyeso komwe katswiri wamakina adzafunika kudula.
Kutsimikizira kwakusanjikiza. Kuwunika kowoneka bwino ndi ma CMM pazinthu zovuta, kuyezetsa kolowera kwa utoto pazovuta zapamtunda, X-ray kapena UT kuti mukhale ndi kukhulupirika kwamkati. Kwa magawo owoneka bwino, nthawi zambiri mumachita zonse zomwe zili pamwambapa. Njira yamapepala - lipoti la kusungunuka, zolemba zoyendera - ndi gawo lalikulu la khalidwe monga gawo la thupi. Ndi umboni wa kulamulira. A foundry kuti sangathe kupereka zogwirizana deta phukusi mwina analibe ndondomeko zogwirizana.
Muyeso Weniweni: Kuthetsa Mavuto, Osati Kungopanga Magawo
Ndiye, ndi chiyani chomwe chimasiyanitsa wogulitsa bwino ndalama kuchokera kwa wamkulu? Si kabukuka. Ndi momwe amachitira zinthu zikapanda script. Aloyi yatsopano imachita mosayembekezereka. Chojambula chimakhala ndi malo otentha. Ubwino wa maziko amawululidwa mu njira yawo yothetsera mavuto. Kodi amangoimba mlandu phula kapena mtanda wachitsulo? Kapena ali ndi kuya kwa uinjiniya kuti agwiritse ntchito DOE yaying'ono, kusintha mawonekedwe amitengo, kusintha mawonekedwe a slurry, ndikubwerera kwa inu ndi yankho ndi deta?
Uwu ndiye mtengo wa mnzake yemwe ali ndi mbiri yozama yogwira ntchito. Pamene Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd. amalankhula pafupifupi zaka makumi atatu chipolopolo nkhungu kuponyera ndi kuponya ndalama, nthawi imeneyo ikuimira laibulale ya mavuto othetsedwa. Mwina adawonapo mtundu wina wazovuta zanu m'mbuyomu. Kukumbukira kwadongosolo kumalepheretsa kuphunziranso kokwera mtengo komanso kuyesa-ndi zolakwika pa dime yanu.
Pomaliza, mkulu khalidwe kuponya ndalama ndi unyolo wa masitepe zana ang'onoang'ono, oganiziridwa bwino. Ndi ntchito yothandizidwa ndi sayansi. Ndizokhudza kuwongolera zosintha zomwe mungathe kuziwongolera (monga kukhuthala kwa slurry ndi kutentha kwa kutentha) ndikumvetsetsa momwe mungasamalire zomwe simungathe kuzichotsa (monga chinyezi chozungulira). Cholinga si ungwiro—ndicho zosatheka m’njira yokhala ndi zinthu zambiri zotentha ndi zakuthupi—koma ndi kusasinthasintha kosalekeza ndi kuchitapo kanthu mwanzeru. Gawo lomaliza lomwe limakumana ndi spec, makina bwino, ndikuchita m'munda? Ndizo zotsatira zake basi. Ubwinowo unamangidwa m'maola, masiku, ndi zaka zisanachoke pomangapo.
