Xa iinjineli zichaza umzi-mveliso womenzi ochanekileyo kumaxwebhu okuthengwa kwempahla, abayenzi nje i-odolo yesinyithi-bafuna ukuphindaphinda kwe-dimensional phantsi kwe-0.02 mm, ukuhambelana kwe-microstructure kwiibhetshi eziphathwa ngobushushu, kunye nokuthembeka komsebenzi emva kweeyure ze-10,000 kwii-valve ze-hydraulic manifolds okanye izindlu zempompo zangaphandle. Sibone iiprojekthi ezininzi ziphelelwa kuba umthengisi waphatha i-cobalt-nickel alloy casting “njengomnye nje umsebenzi wentsimbi.” Ayiyo.
Isizathu Sokuba Indlela Yokuziphatha Yezinto Ezibonakalayo Ilawula Uyilo Lwenkqubo—Hayi Enye Indlela Ejikeleze
I-alloys esekelwe kwi-Cobalt njenge-AMS 5387 okanye i-T800 ayinayo umatshini njengensimbi engenasici. Umsebenzi wabo wokuqina unyuka emva kwe-0.1 mm yobunzulu bokusika. I-conductivity yabo ye-thermal isiqingatha se-304 i-stainless-ngoko ubomi besixhobo buhla nge-60% ukuba uxinzelelo olupholileyo luwela ngaphantsi kwe-70 bar. Kwivenkile yethu, asiqali ngeenkqubo ze-CNC. Siqala ngamashiti edatha ye-metallurgical: ubungakanani besayizi yokuhanjiswa kwengqolowa ukusuka kwi-Foundry, iimephu ze-carbide precipitation post-Solution annealing, kunye ne-tensile curves kuwo omabini amagumbi kunye ne-400 °C. Kungoko kuphela apho sitshixa isantya sokuphotha, ukondla izinyo ngalinye, kunye ne-stepover.
Olu qeqesho lwahlula isakhono sokuphosa esichanekileyo ukusuka kumphakamo wokucaphula. Ipompo enye yaseMntla Melika iOEM isithumelele umzobo wepiston pump cylinder housing-tight GD&T on concentricity (Ø0.015 mm), iindawo ezibalulekileyo zokutywina eziphantsi kweRa 0.4 µm, kunye nemfuneko yobulukhuni be-38–42 HRC emva kokuguga. Umthengisi wabo wangaphambili wayesebenzisa ukugalela isanti yegeneric + nokugqiba oomatshini. Isiphumo? I-37% yesantya se-scrap ngenxa ye-porosity engaphantsi komhlaba kufuphi ne-high-pressure bore. Sitshintshele kwi-investment casting kunye nokugalelwa kwe-vacuum-assisted, songeze uvavanyo lwe-ultrasonic phambi komatshini, kunye nokudibanisa ukuxinzelela uxinzelelo phakathi kokusikeka okukrakra kunye nokugqiba. Isivuno sitsibe ukuya kuma-94%. Inxalenye iphumelele uvavanyo lwe-hydrostatic kwi-1.5 × i-pressure rated-akukho ukuvuza, akukho ukuphazamiseka.
Iindidi ezine zeMveliso-Nganye Yakhelwe ukuFaila-ubungqina bokuSebenza
Sigxila kuphela kumacandelo apho ukusilela kuthwala iziphumo zokusebenza okanye zokhuseleko. Akukho ziphoso zokuhombisa. Akukho zibiyeli zonyamezelo oluphantsi. Intsimbi nje ebaluleke kakhulu kwimishini:
- CNC oomatshini iindawo: I-Multi-axis contouring yeeplagi ze-cobalt eziqinileyo kunye nemilomo, kunye nenkqubo yokuphonononga ukuqinisekisa ukutyeba kodonga ngaphakathi kwe-± 0.05 mm kumacandelo angama-2-mm-thin
- Amacandelo e-cobalt-nickel alloyI-AMS 5387 iinxalenye zempompo ezenziwe kwi-billet ye-T800 eqinisekisiweyo, enokulandeleka okupheleleyo kwebhetshi ukubuyisela kwilog enyibilikayo kunye nesatifikethi sokunyibilika kwe-ESR.
- Ukuphoswa kwentsimbiI-ASTM A48 Udidi lwama-35 lweziseko zempompo yentsimbi engwevu-yenzelwe ukudambisa ivibration, hayi umthwalo omileyo
- Intsimbi kunye neesanti zentsimbiI-AISI 4140 kunye ne-17-4PH yezindlu ze-winch ye-winch centre shaft rollers, ephathwa ngobushushu ukuze ihambelane ne-torsional fatigue specs zobomi
Yonke into ithunyelwa ngengxelo yovavanyo lwezinto (MTR), ingxelo yokuhlola idimensional esayinwe ngumqhubi oqinisekisiweyo weCMM, kunye nelogi enesiphene ebonwayo echazwe nge-ISO 13919-1 indlela yokwamkelwa kwe-weld-nangona kungekho welding eyenzekayo. Ngoba? Kuba abathengi basixelela abaphicothi-zincwadi babo ngoku bayayifuna kubathengisi bendawo yeoli yeTier 1.
Umgangatho awuhlolisiswanga-Uyinjineli, inyathelo ngenyathelo
Ezinye iifektri ziqhuba uhlolo lokugqibela kwiindawo ezigqityiweyo. Sihlola iindawo ezintlanu zokukhangela ezingenakuxoxisana:
- Ukuqinisekiswa kwezinto ezikrwada: Uhlalutyo lweSpectrometric + Uvavanyo lwe-ultrasonic bulk kuyo yonke ikhoyili/billet ngaphambi kokusikwa
- Ijometri ye-As-cast: I-Optical contour scanner ijonga ii-engile eziyidrafti kunye ne-core shift phambi konyango lobushushu
- Imephu yobunzima obusemva kobushushu: Igridi ye-9-point Rockwell C kwiindawo ezibalulekileyo, hayi indawo enye
- Kwinkqubo ye-CMM: Emva kokulungiswa, ngaphambi kokugqiba, ukuqinisekisa ukuba isibonelelo sesitokhwe sihlala sifana
- Ukuqinisekiswa okusebenzayo: Iivalve zoxinzelelo ezivavanywe kwi-1.3 × uxinzelelo lokusebenza; i-winch shafts spin-balanced ukuya kwi-G2.5 nge-ISO 1940-1
Sigcina iirekhodi zedijithali iminyaka eyi-10-kungekhona ngenxa yokuba imimiselo iyayifuna, kodwa ngenxa yokuba umthengi wayekhe walandela ukusilela kwintsimi kwibhetshi enye yeeplagi ze-cobalt ze-2019. Inkqubo yethu yokulandela umkhondo ibavumele ukuba bahlukanise kwaye bathathe indawo yeyunithi ezili-147 kuphela-hayi i-5,000.
Ukuthembeka kuqala kwindlela othetha ngayo-Ngaphambi kokuba i-Chip yokuqala ibhabha
Elona xabiso likhulu ekulahleni ngokuchanekileyo akuyonto okanye umsebenzi. Kukusetyenzwa kwakhona okubangelwe kukungalungelelani kolindelo. Ke sibethelela uphononongo lobunjineli kwisigaba sokucaphula-hayi njengembeko, kodwa njengesango elinzima. Xa umxhasi engenisa umzobo womzimba wevalve yoxinzelelo olungekho semgangathweni, iqela lethu lifaka iflegi yezinto ezintathu kwiiyure ezingama-48:
- I-GD&T callouts ezingqubana neemfuno zoyilo lokuphosa (umzekelo, ukucacisa i-0 ° uyilo kudonga oluthe nkqo lwe-300-mm)
- Umphezulu ugqibezela ukwenzeka ngaphandle kokusila okwesibini (iRa 0.8 µm kumphezulu wesanti ifuna +$12/kg)
- Iimpawu zezinto eziphathekayo ezingakuhoyiyo ukwandiswa kwe-thermal ukungalingani-njengokudibanisa isihlalo sevalve ye-cobalt kunye nomzimba wentsimbi yekhabhoni kwinkonzo yebhayisikile yomphunga.
Asithi "ewe" kuzo zonke izicelo. Sithi "nantsi into esebenzayo, nantsi isizathu, kwaye nantsi impembelelo yeendleko zokhetho ngalunye." Oko kucaca kunciphisa ixesha le-NRE nge-40% ngokomndilili-kwaye kwakha ukuthembela ngokukhawuleza kunayo nayiphi na ibheji yesatifikethi.
Ukufumana iinjineli umzi-mveliso womenzi ochanekileyo amaqabane, ukuthembeka akulobango lokuthengisa. Inokulinganiswa: ≤0.8% izinga le-PPM ye-scrap kumacandelo e-cobalt, i-≤72-iyure yokukhokela i-prototype castings, kunye ne-zero ukuhanjiswa kade kwi-OEMs yaseYurophu ngo-2023. Kukhetha umthengisi ophatha umzobo wakho kungekhona njengefom ye-odolo-kodwa njengesibophelelo sobunjineli esabelana ngaso. Yileyo ndlela iinxalenye ezibaluleke kakhulu zemishini zifumana indawo yazo kwiinkqubo apho ixesha lokuphumla lixabisa i-28,000 yeedola / iyure.
