Lapho onjiniyela bedinga a inkambiso elahlekile yokuphonsa ifektri ye-wax ezingxenyeni okufanele zibambe ukubekezelela okungu-±0.02 mm ngaphansi kwengcindezi ye-hydraulic yamabha angu-350, azibizi ama-foundential foundries. Babiza izitolo ezinamalogi okwelapha ukushisa kwe-cobalt alloy efayeleni, imibiko ye-CMM egxivizwe abacwaningi mabhuku be-ISO 9001, kanye nokuhlangenwe nakho kokuthunyelwa kwezindlu zamaphampu ze-AMS 5387 kubahlinzeki besevisi base-Tier-1 yenkundla kawoyela e-Houston nase-Aberdeen. Lokho kuyiqiniso lokusebenza-hhayi ulimi lokumaketha.
Kungani “Isiko” Lisho Okungaphezu Kwesitembu Sokudweba Nje
Ukukhipha i-wax elahlekile akuyona inkambiso ngoba uthumela ifayela elithi STEP. Kuwumkhuba lapho i-Foundry inqamula izingozi zedizayini ngaphambi kokuthi kuqale ukusebenzisa. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye sabona amaphuzu amathathu okuhluleka aphindelelayo kumadizayini omzimba wamavalvu athunyelwe ngamakhasimende: okokuqala, izigaba ezinodonga oluncane ezingaphansi kuka-4.2 mm eziqhekeka ngesikhathi sokukhululeka kokucindezeleka kwangemva kokusakazwa; okwesibili, imisebe yangaphakathi eyimpumputhe engaphansi kuka-R1.5 ebamba izinsalela zamagobolondo e-ceramic; okwesithathu, ama-callouts e-GD&T acacisa iphrofayili yendawo ngaphandle kokuchaza okwandulela i-datum-okubangela ukungahambi kahle kokusebenza emibuthanweni yephampu ye-piston. Sikumaka lokhu phakathi nokubuyekezwa konjiniyela—hhayi ngemva kokulahlwa. Kungaleyo ndlela "isiko" iba ukubikezela, hhayi ukusabela.
Ukuphatha Ingxubevange Yomhlaba Wangempela, Hhayi Izimangalo Zeshidi Ledatha
Ama-alloys e-cobalt-nickel afana ne-T800 ne-AMS 5387 awenziwanga ngomshini—ayakhohliswa. I-thermal conductivity yabo ingu-1/6 we-304 engenasici. Izinga labo lokuqinisa umsebenzi liyakhuphuka ngemva kokujula okungu-0.15 mm. Ukufakwa kwe-carbide okujwayelekile kuyaphahlazeka lapho uthintana naye okokuqala. Sisebenzisa amathuluzi e-ceramic ahlanganiswe ne-PVD, into epholisa amanzi ngezikhukhula ngokucindezela kwebha engu-42, futhi sikhawulela ukushona kwe-axial kube ngu-0.08 mm iphasi ngayinye. Lokhu akuwona umbono. Kuyisizathu sokuthi imibhobho yethu ye-cobalt alloy iphile izinyanga eziyi-18 kumaphampu e-slurry esivinini esikhulu kuyilapho izimbangi zihluleka ezinyangeni ezi-5. Silandelela ijika lokuqina lwayo yonke iqoqo, ukusatshalaliswa kosayizi wokusanhlamvu, nokuhlukaniswa kwe-interdendritic—ngoba i-microstructure inquma impilo yokukhathala, hhayi nje amandla aqinile.
Ukuhlanganisa Okuqondile Ungakwazi Ukukala
Abahlinzeki abaningi bakhipha izinsiza, ukwenza imishini, noma ukuqeda. Lokho kudala ukukhukhuleka kwe-dimensional. Ukuncipha kwephethini ye-wax akufani nokugqokwa kwe-CNC. Ukuhlanekezelwa kokwelashwa kokushisa akunxeshezelwa ekugayweni kokugcina. Esikhungweni sethu se-Qingdao, iqembu elilodwa liphethe uchungechunge oluphelele: ukutshala izimali → ukuqeda ingcindezi → i-CNC contouring ye-5-axis → i-HVOF coating → ukuhlola ukuvuza. Ngezindlu zesilinda sephampu ye-piston, lokhu kusho ukuthi ukuphuma okuphelele kuhlala ngaphansi kuka-0.015 mm kubude obungu-320 mm—kuqinisekiswe i-laser tracker, hhayi nje i-CMM. Awekho ama-handoffs. Ayikho imidlalo yokusola. Ukulawulwa kwenqubo okulandelekayo nje kusuka kumjovo we-wax kuya embikweni wokugcina wokuhlola.
- Impahla eluhlaza iqinisekiswe ku-ASTM A975 / AMS 5737 enemibiko egcwele yokuhlolwa kwesigayo
- Ukuhlolwa okungaphakathi kwenqubo: ukuqinisekiswa kokuqina kwegobolondo, ukuhlolwa kobukhulu bephethini ye-wax, imephu yobulukhuni yokwelashwa kwangaphambi kokushisa
- Ukuqinisekisa kokugcina: ukuhlolwa kokuvuza kwe-helium ku-1×10⁻⁹ mbar·L/s, ukuhwaqana kwendawo Ra ≤ 0.8 μm ebusweni bokuvalwa okubalulekile, ukumelana nesifutho sikasawoti ≥ amahora angu-1,000 nge-ASTM B117 ngayinye
Lokho Amakhasimende Akudinga Ngempela—Hhayi Lokho Izincwajana Ezikuthembisayo
Abaphathi bokuthengwa kwempahla babuza imibuzo emithathu—futhi bathole izimpendulo ezingacacile kwenye indawo:
“Ungakwazi ukubamba isikhundla sangempela emigodini eyisithupha engu-Ø8.5 mm phakathi kuka-0.01 mm ukuya kudathamu esungulwe endaweni ekhonjiwe?” Yebo—uma i-engeli yokusalungiswa ingu-≥ 1.2° futhi indawo yedatha yenziwe yacaba ngaphambi kokubhobozwa kwembobo. Sizokubonisa idizayini yokulungisa.
"Isiphi isikhathi sakho sokuhola sezingcezu eziyi-12 zepulaki ye-AMS 5387 enentambo engajwayelekile?" Izinsuku ezingama-28 kusukela ekudwebeni ukugunyazwa. Hhayi "amaviki ama-4-6." Hhayi "kuncike ekutholakaleni kwezinto ezibonakalayo." Sigcina amabhilidi e-T800 futhi sigcina izivumelwano zemithombo emibili nabahlinzeki ababili be-cobalt abaqinisekiswe i-AMS e-China naseJalimane.
"Ingabe uyayeseka i-PPAP Level 3 kumasistimu e-automotive hydraulic?" Yebo—ngemibhalo egcwele ye-DFMEA, imidwebo yokugeleza kwenqubo, kanye nezifundo ze-MSA kuzo zonke izici ezibalulekile. Hhayi nje uhlu lokuhlola.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lapho izingxenye zensimbi ezinembayo zihlangabezana nemiphumela yomhlaba wangempela. Uma i-winch center shaft roller ihluleka ku-crane yasolwandle, isikhathi sokuphumula sibiza u-$ 220,000 ngehora. Lapho i-valve yokucindezela ivuza kumojula yokulawula engaphansi kolwandle, ukushintshwa kudinga ukungenelela kwe-ROV kumamitha angu-2,800. Asikho isikhala sokuthi "usondele ngokwanele." Kungakho amakhasimende ebuya—hhayi ngentengo, kodwa ngokuqiniseka kohlangothi, ukungaguquguquki kwe-metallurgical, kanye nokubambisana kobunjiniyela okubhakwe kukho konke ukucaphuna. Ngokuzayo lapho ucacisa ingxenye yesevisi enengcindezi ephezulu, egqokwa kakhulu, noma ebucayi enokugqwala, qala ngokwenza izinto—hhayi nje ijiyomethri. Ithagethi yakho yokuthembeka incike kuyo.
