Lapho onjiniyela becacisa i-gravity die casting yezingxenye zensimbi ezinemba okuphezulu, abagcini nje ngokukhetha inqubo—bakhetha uzakwethu okwazi ukubamba ukubekezelela okungu-±0.05 mm kuzindlu zephampu ye-cobalt alloy kuyilapho egcina ubuqotho besakhiwo ngaphansi kwengcindezi yokusebenza yamabha angu-350. Lelo zinga lokungaguquguquki lihlukanisa a imboni yomkhiqizi we-gravity die casting kusuka endaweni esungulwe yimpahla.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngesilinganiso esincane nsuku zonke. Isekelwe e-Qingdao, e-China, le nkampani iletha izingxenye zabalingisi ezisebenzayo lapho ukwehluleka kungeyona inketho: izindlu ze-piston pump cylinder system ze-hydraulic systems, ama-center shaft rollers amawintshi emoto yobunjiniyela, izingxenye zephampu ze-AMS 5387 cobalt 6 zamathuluzi ensiza kawoyela. Lawa akuwona ama-prototypes noma ama-off-off. Ziyizingxenye zokukhiqiza ezinokulandeleka okuphelele, amarekhodi okwelapha ukushisa, kanye nokuthobelana kwe-GD&T okuqinisekiswe yi-CMM—okuthunyelwe kuma-OEMs kulo lonke elaseNyakatho Melika, i-Europe, naseNingizimu-mpumalanga ye-Asia.
Okwenza amandla abo okukhipha amandla adonsela phansi ahluke akuwona nje umshini — yindlela abaphatha ngayo insimbi njengento eguquguqukayo yokuklama. Abahlinzeki abaningi bathola ama-ingots afakwe ngaphambili futhi bawathele ngokungaboni. I-QINGDAO QIANGSENYUAN isebenzisana ngokuqondile nabahlinzeki bezinto ezibonakalayo abaqinisekisiwe ukuze kuqinisekiswe amandla okuqineka eqeqebana elithile, ukusatshalaliswa kosayizi wokusanhlamvu, nokuhlakazwa kwe-carbide *ngaphambi* kokulungiswa kwesikhunta. Kuma-alloys asekelwe ku-cobalt e-T800, lokho kusho ukuthi ukuqinisekisa ubulukhuni kuhlala ku-42–46 HRC ngemva kokufakwa kwesisombululo—futhi kuqinisekiswe futhi ngemva komshini. Sibone amakhasimende eshintsha esuka kubahlinzeki bezigaba ezintathu ukuya ekuhlanganyeleni okuqondile ngemva kokuthola ukuhlukaniswa okungahambisani kwe-interdendritic ekuqhutshweni okuqhudelana naye okubangele ukuguguleka kwenozi ngaphambi kwesikhathi ezindleleni zoketshezi ezinesivinini esikhulu.
Ukuhamba kwabo okuhlanganisiwe okuqondile kususa amaphutha e-handoff ehlisa ukunemba. Ukusakaza kwe-gravity die cast kwenzeka ezindaweni ezithobela i-ISO ezinokushisa kwesikhunta esilawulwayo (220–260°C), amawindi okushisa alinganisiwe (±5°C), kanye nokuqapha okushisayo kwesikhathi sangempela ngesikhathi sokuqina. Akukho ukuncibilika kabusha kwesibili. Akukho mashini ngaphandle kwesayithi. Imisebenzi ye-CNC ilandela ngokushesha—emishinini ye-axis engu-5 ekwazi ukuhlanganisa amashaneli okupholisa angaphakathi ngaphakathi kwezindlu zamasilinda awugqinsi ongu-40 mm kuyilapho ibambe indawo yangempela phakathi kuka-0.015 mm. Ukwelashwa kokushisa kuhlanganisa emgqeni: isixazululo se-anneal, ukucisha, nokuguga kwenzeka ngaphandle kokususwa kwengxenye. Ukuqedwa kobuso—ukwenziwa ngogesi, ukupeyinta, noma ukunamathiswa kwe-HVOF—kucaciswa ngesidingo somsebenzi ngamunye, hhayi izinketho zekhathalogi.
- Ama-valve okucindezela: Isakazwe ku-ASTM A494 M35-1, ifakwe kumshini wokucaciswa kwe-API 6D Class 600, ihlolwe ukuvuza ku-1.5× ingcindezi yokusebenza
- Izisekelo zamaphampu: Izindlu zensimbi ezisakazwa ngesihlabathi ezinamalugi ahlanganisiwe afakayo, akhulula ukucindezeleka ngaphambi kokugaya okokugcina
- I-cobalt alloy nozzles: Okubalulekile kwe-AMS 5387, ubuhwaqaqe obungalinganisi bendawo engu-Ra ≤ 3.2 µm, akukho ukugaya kwesibili okudingekayo
- Ama-winch shafts angajwayelekile: Ingxubevange ye-T800, i-100% ihlolwe i-ultrasonic, ukuzinza kwe-dimensional kuqinisekisiwe ngemva kokucwiliswa kwemvelo kwamahora angu-72
Abanye bangase baphikise ngokuthi ukukhishwa kwe-investimenti kunikeza imininingwane engcono kakhulu yejometri eyinkimbinkimbi. Kodwa i-gravity die casting iletha izinto ezisebenza kahle kakhulu—ukuminyana okuphezulu, i-porosity ephansi, namandla okuqina aphindaphindekayo—okubalulekile lapho izingxenye zijikeleza phakathi kokuqalisa kuka-20°C kanye nezinga lokushisa elingu-180°C lokusebenza. Silinganise ukuthuthukiswa kwempilo yokukhathala okungama-37% emizimbeni yamavalvu engxubevange ye-cobalt ye-gravity-die-cast ngokuqhathanisa nokulingana nokutshala imali ngaphansi kwamaphrofayili afanayo omthwalo we-pulsating. Umehluko? Ukuqiniswa kokuqondisa okulawulwayo kanye nemigodi enciphayo encishisiwe eduze nezindawo zokucindezeleka ezibucayi.
Ukuthembeka kokulethwa kubangelwa ukuhlela okuqondile—hhayi izithembiso. Ukuhamba kwabo okuthambile kusebenzisa imephu yesikhathi se-takt yomndeni ngamunye wezingxenye: amahora ayi-18 okukhiqizwa kwepulagi ye-cobalt alloy (okubandakanya i-NDT), amahora angama-32 wezindlu zamaphampu ensimbi engagqwali (ngokwelashwa kokushisa nokuhlolwa kokugcina). Izikhathi zokuhola ze-prototype ziqala ezinsukwini zokusebenza eziyi-12—hhayi izinsuku zekhalenda—nempendulo yobunjiniyela ekukhiqizeni ekhishwe phakathi namahora angu-48 okuthunyelwa komdwebo. Ukuhumusha kwe-GD&T akukhishelwa ngaphandle; Ithimba labo le-metrology liqinisekisa izakhiwo zedatha ngokumelene nezidingo zomhlangano osebenzayo ngaphambi kokukhishwa kwamathuluzi.
A imboni yomkhiqizi we-gravity die casting uthola ukwethenjwa ngobufakazi obubhaliwe—hhayi izincwajana. Konke okuthunyelwayo kufaka phakathi isitifiketi sokuthobelana esifaka kuhlu izinombolo zokushisa zempahla engavuthiwe, ama-ID enkatho yokusakaza, imibiko yokuhlola ubukhulu (i-CMM + isiqhathanisi esibonakalayo), namarekhodi okuhlola angakonakali. Lapho i-OEM yepompo yase-Europe ifuna ukulandeleka okugcwele emuva kumsuka we-ore ukuze kuthotshelwe iSigaba VIII se-ASME, i-QINGDAO QIANGSENYUAN inikeze izifinyezo zokuhlola zomhlinzeki kanye nemibiko yokuhlolwa komshini phakathi kwamahora angu-72—akukho kuguqulwa, akukho ukubambezeleka.
Uma ubheka phambili, ukugxila kwabo kwe-R&D kuqondise kuzinqubo eziyingxubevange: ukuhlanganisa ubuqotho besakhiwo se-gravity die casting nokugaya kwe-CNC kwendawo yokuvala okudinga ukucaba kwe-sub-micron. Ukunwetshwa kwesitifiketi kufaka i-AS9100 yezingxenye ze-cobalt ebangeni le-aerospace kanye ne-ISO 13485 yezinhlelo zokuphatha uketshezi lwezokwelapha. Kodwa umnyombo awushintshile—izingxenye eziqondile ezisebenza, hhayi nje ukufika. Ngoba kuma-hydraulics anengcindezi ephezulu, ama-valve angasogwini, noma ama-winch-duty-winch systems, ukunemba kwe-dimensional ngaphandle kokuthembeka kokusebenza kuyizicucu ezibizayo.
