Lapho onjiniyela becacisa ukukhishwa kwesihlabathi sensimbi kumavalvu asebenza ngomfutho omkhulu we-hydraulic noma ama-winch center shaft, abagcini nje ngokukhetha inqubo—babheja ngokuzinza kwe-dimensional, ukulawulwa kwe-microstructure, kanye nokuvumelana kwe-batch-to-batch metallurgical. Kungakho a steel isihlabathi casting ifektri kumele enze okungaphezu kokuthela insimbi encibilikisiwe ezibunjeni. Kumelwe ihlanganise isayensi yokusungula nokunemba kwemishini, ukulandeleka kwezinto ezibonakalayo nokuqinisekisa okusebenzayo—futhi ilethe izingxenye ezisinda emijikelezweni ye-psi engu-20,000 ngaphandle kokuyekethisa.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sibone indlela ukuphrinta okuyinhloko okungaqondani kahle ngayo kubangela ukuhlukahluka kokuqina kodonga okungu-0.15 mm kumasilinda wepompo ye-piston—okwanele ukucupha i-cavitation ngo-3,200 rpm. Siphinde sabona amakhasimende elahla yonke inkatho ngenxa yokuthi ukukhishwa kwe-cobalt-nickel kuphole ngokushesha, kwakha isigaba se-brittle sigma eduze kwemingcele yokusanhlamvu. Lezi akuzona izingozi zethiyori. Ziyizindlela zokwehluleka eziphindaphindekayo—futhi yingakho isikhungo sethu esithobela i-ISO siphatha wonke umsebenzi wokuphonsa isihlabathi sensimbi njengenkontileka yensimbi, hhayi umsebenzi wokukhiqiza.
Ukuhlanganiswa kwethu okume mpo kuqeda amaphuzu ezinhlungu avame kakhulu kumaketanga okunikezela nge-alloy ephezulu. I-Foundry, ukwelashwa kokushisa, i-CNC ye-multi-axis, nokuqedwa kwendawo konke kwenzeka ngaphansi kophahla olulodwa—ngamazinga e-GD&T okwabelwana ngawo, izimiso zokuhlola ezivumelanisiwe, kanye nempendulo yesikhathi sangempela ye-CMM ebuyela emuva ekwakhiweni kwesikhunta. Uma u-oda ingxenye yepompo ye-cobalt ye-AMS 5387 ye-cobalt alloy, unjiniyela ofanayo oqinisekisa umdwebo wakho uphinde asayine kulogu lomlilo, izinga lokucisha, kanye nokuhlolwa kokuqina kokuqina kwe-Rockwell C. Awekho ama-handoffs. Akukho ukulahlekelwa kokuhumusha. Iqembu elilodwa nje eliziphendulela.
- Ubuqotho bezinto ezibonakalayo buqala ngaphambi kokuncibilika: Sithola izingothi ze-T800 ezisekelwe ku-cobalt nensimbi engagqwali ezinemibiko egcwele yokuhlola—hhayi nje amagama ebanga. Yonke inqwaba ihlaziywa nge-spectrographic lapho yamukelwa, futhi sigcina amasampula iminyaka emi-5.
- Ukulingwa kwesihlabathi akukhona "ukunemba okuphansi" lapha: Amaphethini ethu esihlabathi esiluhlaza kanye namaphethini ahlanganiswe ne-resin afinyelela ku-±0.3 mm ukubekezelela komugqa ezicini ezingu-300 mm—aqinile kunabaningi abafaka utshalomali abafuna ama-alloys afanayo—ngoba silawula umswakama, ukucindezela kokucinana, kanye nesikhathi sokunyakaza kwehle kuze kufike kwesibili.
- Ukukhanda kulandela ukusakaza—hhayi ngenye indlela: Sisebenza ngomshini izindawo ezibucayi zokuvala *emva* kokudambisa ingcindezi nokuguga, hhayi ngaphambili. Lokho kuvimbela ukuhlanekezela emizimbeni yevalvu yokucindezela lapho ukuchezuka kokuvuleka okungu-0.02 mm kubangela ukuvuza okungaphezu kuka-10,000 psi.
Abanye bangase baphikise ngokuthi ukukhishwa kwesihlabathi akukwazi ukufana nokufaka utshalomali kumajiyometri ayinkimbinkimbi. Kodwa uma sisebenza, sikhiqiza izisekelo zephampu ezingajwayelekile ezinamashaneli okupholisa angaphakathi, ama-undercuts, namalugi ahlanganisiwe—sisebenzisa ithuluzi lephethini ehlukanisiwe nama-ceramic cores—ngenkathi sibambe ukuhluka kwesisindo ngaphansi kuka-±1.2%. Umehluko? Asiyiphathi i-geometry njengesithiyo. Siyithatha njengepharamitha yedizayini ezoklanywa eduze kwegradient eshisayo nendlela yokuqinisa.
Ikhwalithi ayicwaningwa ekugcineni-yakhiwe kuwo wonke amasango. Ukuqinisekiswa kwempahla eluhlaza engenayo. Ukuhlola okusetshenzwa nge-radiographic ezigabeni ezibalulekile zensimbi nezinsimbi ezingenasici. Ukuhlolwa kokugcina kokusebenza: ingcindezi ye-hydrostatic ibambe ku-1.5 × ingcindezi yokusebenza elinganiselwe imizuzu engama-30, ekhishwa yibhamuza elinguziro. Wonke umbiko uphethe inombolo yenkatho, inombolo yokushisa, i-ID yomsebenzisi, nesitembu sesikhathi. Yonke ingxenye iyalandeleka-hhayi nje ku-batch, kodwa kumjikelezo wesithando somlilo kanye nethangi lokucisha elisetshenzisiwe.
Sinikeza ama-OEMs ezimoto zobunjiniyela adinga ama-winch center shaft roller anokuqina kobuso obungu-62 HRC kanye nokuqedwa okungu-0.4 µm Ra—ngezikhathi zokuhola ezimfishane kunekhwowutheshini yezimbangi zomhlaba wonke zama-prototypes. Sisekela izihlanganisi zesistimu ye-hydraulic ezidinga amavalvu okucindezela anezihlalo ezishintshayo ezishintshwayo ezenziwe ngomshini osuka ekushiseni okufanayo nomzimba—ukuqinisekisa ukuziphatha okufanayo kokunwebeka okushisayo. Futhi sibambisene nabenzi bezinto zikawoyela negesi abafuna amabhomu e-AMS 5387 anoziro esigabeni somphimbo, aqinisekiswe ukuskena kwe-micro-CT.
A steel isihlabathi casting ifektri izuza ukwethenjwa hhayi ngezincwajana—kodwa ngalokho elikwenzayo lapho ishidi lishiya indawo yokuchazwa. Uma umdwebo wakho uthi “R0.5 max,” sihlola ukuthi ingabe leyo radiyasi iyakuthinta yini ukuhlukana kokugeleza endlini yakho yephampu—bese siphakamisa u-R0.8 uma idatha ibonisa ukuthi ithuthukisa ukusebenza kahle ngo-3.7%. Uma ishejuli yakho idinga ukulethwa kwe-athikili yokuqala ezinsukwini eziyi-18, silandelanisa kabusha ukwelashwa kokushisa ukuze sigweme ukubambezeleka kokuphola kwempelasonto—ngaphandle kokudela amandla aqinile.
Uma sibheka phambili, sijulisa umsebenzi wethu ezinqubweni zokwenziwa komshini oyingxubevange: sishumeka amadowels okuqondanisa ngomshini ngokuqondile ezibunjeni zesihlabathi, sisebenzisa ukuqapha okushisayo kwe-in-situ ukuze kulungiswe amazinga okupholisa phakathi nokuthela, kanye namasistimu amasha okuhlanganisa afanelekayo ukuze aqedele indawo ecolekile ekubunjweni kwensimbi ye-carbon steel yesigaba esikhulu. Lokhu akukona ukuhlolwa kwelebhu. Ziyizixazululo ezihlolwe insimu kumafreyimu ezimoto zobunjiniyela ezingamathani angu-42 kanye nenhlanganisela yephampu ye-subsea elinganiselwe ukujula kwamamitha angu-3,000.
Uma iphrojekthi yakho elandelayo ihlanganisa insimbi noma insimbi engagqwali okufanele isebenze ngaphansi kwengcindezi, ukuguga, noma ukugqwala—unganikeli umthengisi obona ukusakaza njengesinyathelo esizimele. Khetha uzakwethu ophatha konke okuthululwayo njengesixhumanisi sokuqala ochungechungeni lokunemba, ukuziphendulela, nokuqina kwezimboni okuqinisekisiwe.
