Lapho onjiniyela bayacacisa imboni yokubumba isikhunta elahlekile izinsiza zezingxenye zensimbi ezibalulekile kumishini, azithengi nje isikhunta—zivikela ukuphindaphindeka kobukhulu, ukulawulwa kwesakhiwo esincane, nokuthembeka kokusebenza ngaphansi kwezimo ezimbi kakhulu. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sikhiqize izingxenye ezingaphezu kuka-12,000 zokutshala imali zemizimba yamavalvu asebenza ngogesi, imibhobho yepompo ye-cobalt-alloy, nezindlu zesilinda sephampu ye-piston—ingxenye ngayinye ifuna ukubekezelelana okungu-±0.05 mm, ukulandeleka okugcwele kwempahla, kanye nokwelashwa kwe-AMS7-7.com Lokho akulona ikhono lethiyori. Yilokho okwenzekayo uma usebenzisa ukukhiqiza okuningi okungu-47 okulandelanayo kwe-T800 okusekelwe ku-cobalt ngaphandle kokwenqatshwa kwebheshi eyodwa.
Kungani ukukhethwa kwefekthri kwe-wax casting elahlekile kushintsha yonke into-ngokwempilo yengxenye yakho, hhayi nje ukuma kwayo
Amathimba amaningi okuthenga aphatha ukutshala imali njengenqubo “yebhokisi elimnyama”: thumela imidwebo, linda amaviki angu-6–8, bese uhlola. Kodwa ezinhlelweni zamanzi ezinomfutho ophezulu noma uwoyela negesi yasogwini, iqoqo elilodwa le-microporosity esihlalweni sevalvu yokucindezela lingabangela ukwehluleka ukwehla. Sibone amakhasimende amathathu ebuyela kithi ngemva kokwehluleka kwabathengisi bokuqala—hhayi ngoba umphakeli wabo wokuqala wayengenazo izinto zokusebenza, kodwa ngenxa yokuthi babephatha ukwakheka kwesikhunta njengokudluliswa kwejiyomethri, hhayi ukumodela kwe-thermal dynamics. Ifekthri yethu elahlekile ye-wax casting molds iqala ngokulingisa ukuqiniswa—hhayi ukwenziwa kwephethini ye-wax. Yonke isikhunta sidala ama-gradients akhethekile e-alloy, isiphithiphithi esidalwa yi-gating, namazinga okupholisa asendaweni. Ku-AMS 5387 cobalt alloy, lokho kusho ukulungisa ijometri ye-sprue ngo-1.8° ukuze kuvinjwe ukuhlukaniswa kwe-dendritic endaweni esibonakalayo yesango. Ngezisekelo zephampu yensimbi engagqwali, kusho ukushumeka izimbobo ze-thermocouple ngokuqondile kusikhunta segobolondo le-ceramic ukuze kuqinisekiswe isikhathi sangempela sokuqina ngokumelene nokubikezela kwe-FEA.
Awudingi amakhono "ongeziwe" - udinga ukulawula okuhlanganisiwe okuqondile lapho kubaluleke kakhulu
Abanye abahlinzeki benza isikhunta sangaphandle, abanye benza imishini yangaphandle, nokwelashwa okuningi kokushisa okuvela ngaphandle. Lokho kuhlukana kudala izikhala: ukusakaza kungase kudlule ukuhlolwa kobukhulu kodwa kuhluleke ukuhlola ubulukhuni ngoba u-opharetha wesithando somlilo usebenzise isilinganiso serempu esihlukile kunesishiwo. Esikhungweni sethu esithobela i-ISO e-Qingdao, ithimba elifanayo liphatha idizayini yesikhunta, ukwakhiwa kwamagobolondo e-ceramic, ukunemba kokuqedwa kwe-CNC, nokwelashwa kwe-vacuum-heat—konke ngaphansi kophahla olulodwa, ngezindinganiso ezabiwe ze-metrology. Lapho iklayenti lase-Europe lidinga imizimba yamavalvu okucindezela angu-240 ku-316 yensimbi engagqwali ene-Ra ≤ 0.4 µm ekuqedeni okungaphezulu kumaphaseji okugeleza angaphakathi, seqe ukupholisha kwesibili ngokuphelele. Kanjani? Ngokwenza isikhunta segobolondo le-ceramic ngemigudu yamathuluzi ye-axis engu-5 ephindaphinda ukubekezelelwa kokugcina kwekhonta—bese kusetshenziswa imijikelezo elawulwayo yokukhipha i-waxing kanye nokutubeka ukuze kulondolozwe lokho kwethembeka ngokusakaza. Umphumela: 98.7% isivuno sokuqala, ukusebenza kabusha okuyiziro, nokulethwa ezinsukwini ezingama-22 esikhundleni sokucashuniwe ezingama-38.
Izindleko zangempela zokubambisana kwefekthri "okujwayelekile" kwe-wax casting molds
Amakhasimende avame ukubuza: "Ingabe ungakwazi ukufanisa intengo yethu yamanje yomthengisi?" Impendulo yethu ihlale ifana: "Asihlole sobabili." Ngonyaka odlule, senze izivivinyo ezilandelanayo ngama-oda afanayo angu-18 okuphonsa insimbi—i-GD&T efanayo, i-spec yempahla efanayo, iwindi elifanayo lokulethwa. Umthengisi onezindleko eziphansi ulethwe ngesikhathi—kodwa u-31% wayedinga ukugaya ngemva kokusakazwa ukuze kuhlangatshezwane nokubekezelelwa kwephrofayela. Okwethu kube nokwamukelwa okuqondile okungu-92% komhlangano. Kungani? Inqubo yabo yokwenza isikhunta kusetshenziswa ukuhlanganiswa kwe-wax eyenziwe ngesandla; eyethu isebenzise umjovo ozenzakalelayo onokuqapha kwengcindezi yomgodi wesikhathi sangempela. Lowo mehluko ongu-0.03 mm wokuqondanisa okuyisisekelo awuzange ubonakale emibikweni ye-CMM kwaze kwaba ngemva komshini—lapho izindleko ze-scrap zifinyelela ku-$220 ingxenye ngayinye. Izindleko zangempela aziyona iyunithi yentengo. Isamba sezindleko ezitholiwe ngengxenye ngayinye yokusebenza, okuhlanganisa umsebenzi wokuhlola, izinsalela zokuphinda zisebenze, kanye nobungozi beshejuli. Sibhala konke ukuchezuka—kwehle kuze kufike ezingeni lokushisa elinembile lenqwaba yesikhunta segobolondo ngalinye—ukuze wazi kahle ukuthi kungani ingxenye yakho yenza.
Okulandelayo akuwona umthamo owengeziwe-ubuciko obujulile be-alloy
Sandisa amandla ethu emboni elahlekile ye-wax casting molds—hhayi ngokungeza imishini, kodwa ngokujulisa ubuhlakani be-metallurgical. Njengamanje, siqinisekisa inqubo eyingxube yezingxenye ze-T800 alloy: ukufakwa kwe-investimenti okulandelwa ukuncibilika kwe-laser okukhethiwe kokugqokwa kwezindawo ezigugile. Lena akuyona ithiyetha ye-R&D. Ixazulula iphuzu lobuhlungu bangempela: amakhasimende adinga ama-cobalt-nickel shaft rollers anezindawo eziqinile (HRC 58-62) kodwa ama-ductile cores (≥35% elongation). Izindlela zendabuko zidinga ukuqina kokufakwa kwangemuva kokusakazwa—okubhidliza amajiyometri anezindonga ezincane. Isixazululo sethu siletha zombili izakhiwo ekuhambeni komsebenzi okukodwa, ngokuqinisekiswa okugcwele kwe-NDT esigabeni ngasinye. Uma isicelo sakho sidinga kokubili ukumelana nokugqwala okukhulu futhi ukuqina komthelela—noma uma umphakeli wakho wamanje ephatha i-AMS 5387 “njengenye nje engenabala”—udinga uzakwethu ongaboni isikhunta njengethuluzi, kodwa njengongqimba lokuqala lomsebenzi olunjiniyela. Kuqala kanjalo ukunemba.
