Izixazululo zefekthri yokuphonsa isihlabathi sezimboni zidinga ngaphezu kwensimbi encibilikisiwe nezibungu. Zidinga ukulawulwa kobukhulu ngaphansi kwengcindezi yokushisa, ukungaguquguquki kwe-microstructure kuzo zonke izindlu zephampu ezingama-50-kg, nobuqotho obungaphezulu obusinda ekushicileleni i-hydraulic yamabha angu-300—ngaphandle kokusebenza kabusha. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sifake izingxenye zensimbi nezensimbi ezingaphezu kweziyi-12,000 kusukela ngo-2018 lapho ukwehluleka kungesona isiphithiphithi—isikhathi sokuphumula esingahleliwe endaweni kawoyela engasogwini noma i-cavitation empompini ye-slurry yezimayini. Kungakho "imboni yokukhipha isihlabathi yemboni" isho okuthile okunembayo lapha: hhayi ivolumu, kodwa ukuphindaphinda okuqinisekisiwe ku-high-alloy, izinhlelo zokusebenza zokubekezelela kancane.
I-Sand Casting Ephethe I-GD&T—Hhayi Ukuma Kuphela
Izitolo eziningi zokuphonsa isihlabathi zihlangabezana nemininingwane ye-ASTM A159 noma i-EN-GJL-250. Bambalwa ababamba u-±0.15 mm ku-ID ye-cylinder bore engu-320-mm ngemva kokunyakaza nokukhululeka kwengcindezi. Senza kanjalo—ngoba inqubo yethu iqala ngaphambi kokuba iphethini ithinte isihlabathi. Onjiniyela bethu babuyekeza ama-callouts akho e-GD&T *ngaphambi* kwesakhiwo sesikhunta, bemaka lapho ama-engeli asalungiswa engqubuzana nokubekezelelana kwezindawo zangempela noma lapho ubungozi bokushintshashintsha bungaphezu kwemikhawulo yokusebenza. Isibonelo, izindlu zesilinda sephampu ye-piston zidinga ukujula okungu-≤0.08 mm phakathi kobuso obungagxili bokubhoboza nokwe-flange. Izinqubo ezijwayelekile zesihlabathi esiluhlaza zikhukhuleka ngaphezu kuka-0.25 mm. Sisebenzisa isihlabathi se-silica esiboshwe nge-resin esikwazi ukungena okulawulwayo (120–140) kanye namabhokisi anembe angumongo afakwe ku-±0.05 mm—bese siqinisekisa konke ukulingisa nge-Zeiss CONTURA CMM ngokuqhathaniswa ne-CAD egcwele. Akukho ukucabanga. Cha “kusondele ngokwanele.”
Lapho I-Cobalt Alloys Imisa Ezinye Izinsiza
I-AMS 5387 ingxube ye-cobalt? Imibhobho esekelwe ku-T800 yomjovo we-abrasive slurry? Lezi akuzona izinselele zokuphonsa-izicupho zensimbi. Isikhunta esijwayelekile sesihlabathi siqhekeka ngaphansi kwezinga lokushisa elithela i-T800 lika-1,350°C. Ukuguguleka kwesihlabathi kungcolisa ukuncibilika. Ukukhula okusanhlamvu kuchitha impilo yokukhathala. Sixazulula lokhu ngezendlalelo ezintathu: Okokuqala, isikhunta esimbozwe nge-ceramic ngokwezifiso esisekelwa i-zirconia simelana nokushaqeka okushisayo futhi sinqande ukuthwebula kwe-silicon. Okwesibili, ukuthulula okusizwa nge-vacuum kunciphisa isiphithiphithi-futhi kuqede igesi eboshiwe eyenza i-microporosity endaweni yokuqina kancane kwe-cobalt. Okwesithathu, isixazululo se-post-cast annealing ku-1,180 ° C ±5 ° C, esibanjwe amahora angu-4 ezithandweni ezilawulwa yi-atmosphere, bese sipholiswa ngomoya ukuze sikhiye ukuhlakazeka kwesigaba se-Laves-fase. Umphumela: Izingxenye ze-AMS 5387 zidlula i-ASTM E112 usayizi wokusanhlamvu 4–6 ngokungaguquki. Amakhasimende abika impilo yesevisi ende engu-3.2× uma kuqhathaniswa nokulingisa izimbangi ezihlalweni zamavalvu zephampu ezinomfutho ophezulu.
Kungani Ukuhlanganisa Okuqondile Kushaya Ukuthuthwa Kwe-“Casting + Machining”
Abanye abahlinzeki baphonsa izindlu, bazithumele esitolo se-CNC, bese bethumela kabusha ukuze kuqedwe. Ukudluliswa ngakunye kwengeza ingozi: ama-datum angaqondani kahle, umonakalo ongarekhodiwe wokubamba, amarekhodi okuphatha ukushisa alahlekile. Sisebenza ngomshini zonke izinhlobo zensimbi—amavalvu okucindezela, amarola e-winch center shaft, izisekelo zokumpompa—ekhampasini efanayo, sisebenzisa izindawo zedatha njenge-cast njengezithenjwa zokusetha. Imishini yethu ye-5-axis DMG MORI NTX 1000 isike ama-bores wokugcina ngenkathi ibambe umugqa wokuhlukanisa isikhunta njengo-Z-zero. Lokho kususa iphutha elinqwabelene ekukhwezeni kabusha. Kuphinde futhi kusivumele ukuthi sishiye isitoko esibalulekile ezindaweni ezibucayi—u-0.8 mm ebusweni bepulaki ye-T800, isibonelo—ukuze ukugaya kokugcina kuzuza u-Ra 0.4 µm *ngemuva* kokwelashwa kokushisa, hhayi ngaphambili. Ukulandeleka kwakhelwe ngaphakathi: ingxenye ngayinye iphethe ikhodi ye-QR exhuma kulogi yayo encibilikayo, umbiko we-X-ray, imephu yokuqina, kanye nemiphumela ye-CMM. Azikho izindlela zephepha. Akukho ukuqagela.
Ukulethwa Kwangempela—Akuzona Izikhathi Zokuhola Ezithenjisiwe
“Amaviki angu-8–12” asho lutho uma ulayini wemoto yakho yobunjiniyela umiswa evikini le-10. Sizibophezela ezinsukwini zokulethwa kuphela ngemva kokuqinisekisa ukufakwa kwamathuluzi, izitifiketi zezinto ezibonakalayo, namandla—hhayi ngemva kokucaphuna. Amaseli ethu okukhiqiza amancane asebenzisa imijikelezo yenqwaba engaguquki: isethi yesikhunta esisodwa ngewindi lezinsuku eziyi-14, ubuningi bamayunithi angama-40 ngebheshi ngayinye yokusakazwa kwensimbi okuyinkimbinkimbi. Lokho kuvala i-WIP, kuveza izingqinamba kusenesikhathi, futhi kuqinisekisa ukuthi sizothumela ama-prototypes ezinsukwini ezingu-22—hhayi “ngokushesha ngangokunokwenzeka.” Ngonyaka odlule, u-98.7% wama-oda athunyelwe ngedethi yokuzibophezela noma ngaphambi kwayo. Ukulibaziseka okungu-1.3%? Konke kulandelelwa ezinguqukweni zobunjiniyela ezicelwe yikhasimende *ngemuva* kokugunyazwa kwephethini—hhayi ukwehluleka kwangaphakathi. Sabelana ngamadeshibhodi okukhiqiza esikhathi sangempela namakhasimende abalulekile: isimo sesikhunta, izingodo zokuthulula, izitembu zesikhathi zokuhlola. Ukungafihli akukona ukumaketha. Kuyindlela ogwema ngayo ukulwa nomlilo.
Uma udinga imboni yemboni yokukhipha isihlabathi esiphatha umdwebo we-valve yakho yokucindezela njengengxenye ebalulekile yendiza-hhayi ingxenye yempahla-udinga ukulawula okuqinisekisiwe phezu kokuziphatha kwe-alloy, iqiniso le-dimensional, nobunikazi bokuphela ukuya ekupheleni. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iletha lokho. Hhayi njengesethembiso. Njengomphumela ophindaphindwayo.
