Xa iinjineli zicacisa i-nickel esekelwe kwi-alloy parts, azikhethi nje izinto eziphathekayo-zibophelela ekusebenzeni phantsi koxinzelelo, ubushushu kunye nomhlwa. Ukungalungeli okukodwa kuzinzo okanye ulwakhiwo lwe-microstructure lunokwehla lube kukungaphumeleli kwempompo, ukuvuza kwevalvu, okanye ixesha lokuphumla elingacwangciswanga kwiinkqubo zamanzi okanye izixhobo ze-oyile. Yiyo loo nto ukukhangela kwi-a i-nickel esekelwe kwi-alloy parts factory ayikho malunga nexabiso lodwa-limalunga nokuphendula kwe-metallurgical, inkqubo yokuqeqeshwa, kunye nempendulo eqinisekisiweyo kwimijikelezo yoxinzelelo lwehlabathi lokwenene.
Kutheni i-AMS 5387 kunye ne-T800 zifuna ngaphezu koMatshini oMgangatho
Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype-hayi ngenxa yeziphene zoyilo, kodwa ngenxa yokuba umthengisi wayengenawo amava nge-cobalt-nickel superalloys. I-AMS 5387 i-cobalt alloy 6 kunye ne-T800-based based materials aziphathi njenge-316 engenasici. Basebenza nzima ngokungqongqo. I-conductivity yabo ye-thermal iphantsi. Izixhobo zokusika zinxiba ngokukhawuleza ngaphandle kokuba amaxabiso okutya, ukuhanjiswa kwezinto ezipholileyo, kunye nejiyometri yesixhobo zihambelana ngokuchanekileyo nobulukhuni obuthile bebhetshi kunye nokwakheka kweenkozo.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-AMS 5387 nozzle okanye i-T800 ye-shaft roller yeziko iqala ngokulandelelwa kwezinto ezikrwada eziqinisekisiweyo-kungekhona nje iziqinisekiso zokusila, kodwa iirekhodi zonyango lobushushu ezikwinqanaba leqashiso ezinqamlezileyo zokuphosa izingodo. Siqhuba uhlalutyo lwe-spectrographic olungenayo kuyo yonke ikhoyili okanye ingot. Ukuba umxholo wekhabhoni ukhukuliseka ± 0.02%, siyavalela kwaye siphinde sivavanye ngaphambi kokuba silayishe kwi-CNC okanye kwimigca yokuphosa imali. Oku akukho overkill. Yindlela esibamba ngayo ± 0.005 mm ukunyamezela kwi-200 mm yezindlu zepiston yepiston ye-cylinder ezisebenza kwi-420 bar.
Ukudityaniswa kwethu nkqo kwenza umahluko: ukuphosa, ukwenziwa, kunye nokugqiba kwenzeka phantsi kophahla oluthobela i-ISO. Akukho zizandla zithetha ukuba akukho mkekelo phakathi kwejiyometri ye-as-cast kunye nokuthotyelwa kwe-GD&T yokugqibela. Sisebenza ngomatshini ngokuthe ngqo kwisanti eluhlaza okanye izikhewu zotyalo-mali-akukho ukulungiswa okwesibini okuzisa impazamo yolungelelwaniso. Kwiijometri ezingekho mgangathweni-ezifana ne-asymmetric winch shaft rollers ene-spline edibeneyo kunye neejenali ezithwele-sisebenzisa i-5-axis yokugaya ngaxeshanye kunye ne-in-probing ye-laser yokuqinisekisa ukuthembeka kwe-contour ngaphambi kokukhulula.
Apho “isiko” sithetha iNtsebenziswano yobuNjineli—hayi nje iNguqulelo yeCAD
Abanye abavelisi baphatha iiodolo zesiko njengonxano kwiikhathalogu eziqhelekileyo. Sibathatha njengentsebenziswano yokusombulula iingxaki. Xa i-OEM yempompo yaseYurophu isithumelele umzobo weplagi ye-AMS 5387 enemitha emithathu enqumlanayo yangaphakathi kunye ne-0.8 µm Ra imfuneko yokugqiba umphezulu, umbuzo wethu wokuqala yayingengo "Ngaba ungavuma ikhowuti?" Yayisithi "Yeyiphi indlela yokusilela ozama ukuyithintela?"
Kuvela ukuba, ukukhukuliseka kwe-cavitation kwi-radius junction kubangele ukusilela kwintsimi emva kweeyure ze-1,200. Ngoko ke sicebise i-electropolish ye-post-machining yendawo-eqinisekisiwe yi-SEM imaging-ukukhupha i-micro-tears eshiywe kukugaya okuqhelekileyo. Sikwacebise ukutshintshwa kolandelelwano lonyango lobushushu: isisombululo se-anneal *phambi* komatshini wokugqibela, emva koko ukwaluphala *emva*, ukutshixa amandla okuqina ngaphandle kokubeka esichengeni ubuqhetseba. Icandelo liphumelele iiyure ezingama-3,500 zovavanyo olukhawulezileyo lobomi. Eso siphumo savela kwingqiqo yesizinda-hayi nje amandla.
Eli nqanaba lothethathethwano liyasebenza kuba iqela lethu libandakanya iinjineli zezicelo ezixhase inkqubo yehydraulic eyakha kuwo wonke uMntla Melika kunye noMzantsi-mpuma Asia. Bathetha i-GD&T ngokutyibilikayo. Bafaka iflegi kwimingcipheko yokwenziwa kwangoko-njengokucacisa i-0.2 mm irediyasi kumngxuma onzulu oyi-12 mm onzulu apho ukufikelela kwesixhobo kunciphisa ukukhutshwa kwetshiphu. Asilindi ukuba inxalenye yokuqala eyaliweyo iqalise loo ncoko.
Ukulawulwa koMgangatho oNgayeki kwiNgxelo yeCMM
Ingxelo yeCMM iqinisekisa imilinganiselo. Ayiqinisekisi imfezeko yokusebenza. Ke iprothokholi yethu yokuhlola ingena nzulu: ukuqinisekiswa kwezinto ezingenayo, ukuqina kwenkqubo kwimephu kumanqaku amathathu ngokuphosa, ukuskena okugcweleyo okugcweleyo kweendawo zokutywina ezibaluleke kakhulu, kunye novavanyo lokugqibela lokusebenza-kubandakanya ukujongwa kokubola koxinzelelo kuyo yonke imizimba yevalvu ukuya kuthi ga kwi-600 bar.
- Sigcina umkhondo ogcweleyo: inombolo yobushushu, iqashiso lokuphosa, uguqulelo lwenkqubo ye-CNC, i-ID yomsebenzisi, kunye neelog zokulinganisa kuyo yonke igeyi esetyenziswayo.
- Siqinisekisa ukugqitywa komphezulu kunye neeprofilometers kunye nothelekiso olubonakalayo ngokuchasene nemigangatho ye-ASTM B487
- Senza uvavanyo lokutshiza ityuwa (i-ASTM B117) kwiindawo ezigqityiweyo xa ukuxhathisa umhlwa kubalulekile.
Akukho zinqanawa zebhetshi ngaphandle kwerekhodi yokuhlola esayiniweyo-kwaye akukho rekhodi icoliweyo ngaphandle kokuba yonke indawo yokukhangela ihambelana nemilinganiselo yokwamkelwa kwabathengi, hayi nje imida yangaphakathi.
Ukuthembeka akusilo ibango-Kulinganiswa ngokuNxibelelana kokuhanjiswa
Imveliso yesiko ethembekileyo ithetha ukubetha imihla ebekiweyo ngaphandle kokuncama ukuchaneka. Siye sagcina> I-97% ngexesha lokuhanjiswa kwexesha lokuveliswa kwevolumu ephakathi liqhuba kwiinyanga ezidlulileyo ze-27-kungekhona ngamaxesha okukhokelela kwi-padding, kodwa ngokufakela iindlela zokuhamba komsebenzi ezinqabileyo ekucwangcisweni komjikelo wokuphosa, ukucwangciswa kwe-CNC, kunye nokulawulwa komgca wokushisa ukushisa. Iiodolo zeprototype zihamba ngeeseli zobunjineli ezizinikeleyo. Ukuqhuba kwemveliso kuxhokonxa izilumkiso zokuzalisa izinto ezizenzekelayo ezibotshelelwe kumaxesha okukhokela ababoneleli. Akukho "mali yokungxama" kwimisebenzi engxamisekileyo-ingxoxo nje zokurhweba elubala: "Singakwazi ukuhambisa ngeentsuku ezili-18 ukuba sihlengahlengisa ishedyuli yonyango lobushushu. Okanye ngeentsuku ezingama-22 ngokuguga ngokupheleleyo ngokwe-AMS spec."
Ukujonga phambili, sandisa i-R&D kwiinkqubo zokwenziwa kwe-hybrid-machining-ingakumbi malunga ne-net-shape investment casting of complex nickel based alloy parts, ilandelwa bubuncinci obuchanekileyo bokususwa kwe-stock CNC. Iziphumo zakwangoko zibonisa i-32% yenkunkuma engaphantsi kwenkunkuma kunye ne-20% ekhawulezayo yokuphuma kumacandelo afana neevalvu zoxinzelelo lwee-port ezininzi. Injongo yethu ayikokuhlangabezana neenkcazo zanamhlanje. Kukunceda abathengi bayile iinkqubo zangomso ezinokunyamezelana, uxinzelelo oluphezulu, kunye namathuba amade eenkonzo.
Ukuba iprojekthi yakho elandelayo ibandakanya i-nickel based alloy parts-ngakumbi i-AMS 5387, T800, okanye amanye amabakala aphezulu e-cobalt-nickel-qala ngokuziphatha kwezinto eziphathekayo, kungekhona nje imizobo. Khetha iqabane elinolawulo lwenkqubo oluhambelana nolindelo lwakho lokusebenza. Khetha ukuthembeka okwakhelwe kwinyathelo ngalinye-elingathembiswanga kwiphepha lokuthengisa.
