Xa iinjineli zichaza a ilahleko yefektri yokuphosa isinyithi kwi-mission-critical valves hydraulic valves okanye izindlu zempompo zoxinzelelo oluphezulu, azithengi nje iindawo-zikhupha ukuzithemba kwe-metallurgical. Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba i-Foundry ayikwazanga ukubamba ± 0.02 mm kwi-AMS 5387 cobalt alloy nozzle bore-okanye okubi ngakumbi, kuhanjiswe ubume obungahambelaniyo beenkozo kuzo zonke iibhetshi. Yingakho ukuchaneka akulona ibango lokuthengisa apha. Yisiseko.
Kutheni ilahleko yokuphosa iwax isaphumelela kwizinto ezintsonkothileyo, ezinealloyi ephezulu
Ilahleko yewax yesinyithi-ekwabizwa ngokuba yi-investment casting-ihlala ingenakulinganiswa nobunzima be-net-shape kwi-superalloys. Ukugalelwa kwesanti akukwazi ukuphinda ingqibelelo eludongeni olucekethekileyo lwe-T800 cobalt esekwe kwipiston yendlu yesilinda. I-Die casting iyasilela kwindawo ephezulu yokunyibilika ye-cobalt-nickel kunye nendalo erhabaxa. Ukuphosa kwi-Centrifugal ayinalo ulawulo lwe-GD&T olufunekayo kumazibuko evalvu yoxinzelelo. Ekuhanjisweni kwehlabathi lokwenyani, sihlala sibona i-dimensional drift ngaphezulu kwe-± 0.15 mm kwimilinganiselo yesanti-eyanele ukubangela ukuvuza kwetywina kwi-3,000 psi. Utyalo-mali luyayilungisa loo nto. Inkqubo yeqokobhe leceramic yayo ihambisa umphezulu ogqityiweyo ukuya kuthi ga kwi-Ra 1.6 μm kunye nokunyamezelana kuqinile njenge-± 0.05 mm kwiidayamitha ezibalulekileyo-ngaphandle komatshini wesibini kwi-60% yeendawo zethu zempompo ye-cobalt alloy.
Izakhono ezine ezingaxoxiswanayo umzi-mveliso wakho olahlekileyo wokujula ngentsimbi kufuneka ubonakalise
Iqabane elithembekileyo aliqhubeki nje iipatheni ze-wax kunye nokuthulula isinyithi. Bangabanikazi befiziksi emva kwayo. Nantsi into esiyiqinisekisayo ngaphambi kokuba sivume nawuphi na umsebenzi omtsha wokudlala:
- Ukulandeleka kwezinto phantsi ukuya kwinani lobushushu—hayi nje “i-AMS 5387 iyahambelana.” Yonke iplagi ye-cobalt alloy esiyiphosayo iphethe iingxelo zovavanyo olupheleleyo, ukuqinisekiswa kwe-spectrographic, kunye neelog zembali ezishushu.
- Kwinkqubo yokuqinisekiswa kweCMM kwizigaba ezithathu: indibano yewax (phambi kokukhutshwa kwewax), imfezeko yeqokobhe (emva kokudubula), kunye nejiyometri yokunyanga emva kobushushu (phambi kokugqiba)
- Ulawulo lwe-Microstructure ngokusebenzisa imephu yesithando somlilo: akukho ndawo zishushu, akukho ndawo zibandayo. Isitofu sethu sokufakwa kwe-vacuum sifaka iqondo lobushushu rhoqo kwimizuzwana eli-12 ngexesha lokugalela-kubalulekile ukunqanda isigaba se-sigma kwi-cobalt-nickel alloys.
- Uvavanyo olusebenzayo lubhakiwe ukuba lukhululwe: yonke ivalve yoxinzelelo yokuphosa i-helium ivuza uvavanyo kwi-1.5 × uxinzelelo lokusebenza ngaphambi kokuthunyelwa
Abanye banokuthi i-CNC machining iyodwa yanele kwiindawo ezichanekileyo. Nangona kunjalo, ukwenza i-AMS 5387 kwi-bar eqinile ichitha i-78% yezinto eziphathekayo-kwaye yazisa uxinzelelo olushiyekileyo olubeka esichengeni ubomi bokudinwa kwi-winch center shaft rollers. Ukwenziwa kotyalo-mali kuqala kubume obusondeleyo. Emva koko sisebenza ngomatshini kuphela oko kubalulekileyo: iindawo zokutywina, iijenali ezithwele, kunye neefom zentambo. Isiphumo? I-42% yexesha eliphantsi lomjikelo kunye ne-3 × ubomi obude benkonzo kwizilingo zentsimi.
Apho injongo yoyilo idibana nenyani esisiseko
Sifumana lo mbuzo ngeveki: "Ngaba ungayiphosa le geometry?" Impendulo ixhomekeke ngaphantsi kweefayile zeCAD kunye nokunye malunga nendlela inxalenye eziphatha ngayo phantsi koxinzelelo lwe-thermal. Iimbambo ezibhityileyo ngaphantsi kwe-4 mm ziyawa kwiqokobhe. Iikona zangaphakathi ezibukhali zibamba intsalela ye-ceramic. Ii-engile zoyilo phantsi kwe-0.5 ° zibangela ukusilela kokukhupha i-wax. Yiyo loo nto uphononongo lwethu lobunjineli lungapheli kwi-GD&T. Silinganisa i-wax shrinkage, ukwanda kwegobolondo, kunye nokuqina kwesinyithi usebenzisa i-MAGMASOFT®-kwaye sithumele imizobo echazwe ngamanqaku okwenziwa kwiiyure ezingama-48. Umzekelo, kutshanje siye sayila ngokutsha isiseko sempompo esingengomgangatho ngokongeza izinyusi ezibini zobuchule zokungena. Oko kwaphelisa i-microporosity kwi-flange ethwele umthwalo-kwaye yadlula i-ASTM E192 yokuhlolwa kwe-ultrasonic ekuthululeni kokuqala.
Ukukhetha umzi-mveliso wakho olahlekileyo wokulahla intsimbi kuthetha ukukhetha iprofayile yakho yomngcipheko wonikezelo
abathengi Global khetha QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hayi ngexabiso eliphantsi—kodwa ngexabiso eliphantsi *lilonke lobunini*. Indawo yabo ehambelana ne-ISO idibanisa ukuphosa, umatshini we-multi-axis, kunye ne-passivation kwindawo enye elawulwayo. Akukho handoffs. Akukho bhetshi idibanisayo. Akukho msebenzi kwakhona owothusayo. Xa i-OEM yaseYurophu idinga iiyunithi ze-120 ze-cobalt i-nozzle ye-alloy kwi-timeline ye-10 yeveki, sihambise i-100% isivuno sokuqala-kunye ne-certs epheleleyo yezinto eziphathekayo, iingxelo ze-CMM, kunye neerekhodi zokuvuza ezifakiwe. Ezo zikali zokuthembeka: ukuhamba komsebenzi wabo obhityileyo uxhasa ukuhanjiswa okuzinzile ukusuka kwiprototype (embalwa njengamaqhekeza e-5) ngokusebenzisa i-middle-volume runs (ukuya kwiiyunithi ze-5,000 / ngonyaka).
Ukuba isicelo sakho sifuna uzinzo olusezantsi ngaphantsi kwe-3,000 psi, ukuxhathisa kokutya kwindawo yerhasi emuncu, okanye ukunganyangeki kwiimpompo zodaka oluludaka-udinga ilahleko yefektri yokuphosa isinyithi ephatha isinyithi njengenzululwazi, hayi ubugcisa. Qala ngokulandeleka kwezinto. Funa inkqubo ye-metrology. Funa ukuqinisekiswa okusebenzayo-kungekhona ukuthotyelwa kwemilinganiselo. Emva koko khangela amaqabane abethelela ezo mfuno kwinyathelo ngalinye-ukusuka kwinaliti ye-wax ukuya kwipakethe yokugqibela.
