Isevisi yokukhipha i-wax iletha ukunemba kobukhulu obungenakuqhathaniswa ezingxenyeni zensimbi ezisebenza ngaphansi kwengcindezi enkulu, ukuguga, noma ingcindezi yokushisa. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sikhiqize izingxenye ezisakazwa utshalomali ezingaphezu kuka-12,000 kusukela ngo-2018—ngasinye silandeleka ngenqwaba yezinto ezingavuthiwe, umjikelezo wokwelapha ukushisa, kanye nombiko wokugcina wokuhlola we-CMM. Lokhu akulona ikhono lethiyori. Ukusebenza kwansuku zonke kwemizimba yama-valve asebenza kubha engu-450, imibhobho ye-cobalt alloy ephethe igesi ephumayo engu-650°C, kanye nezindlu zokumpompa ezakhiwe ngomshini zaba ±0.015 mm GD&T callouts.
Kungani isevisi yokukhipha i-wax ibalulekile uma ukunemba kungaxoxiswana ngakho
Ukutshala izimali kuqala ngephethini ye-wax—ephindaphinda ingxenye yokugcina yejometri. Leyo phethini imbozwa nge-ceramic slurry, ikhishwe i-dewax, futhi ifakwe esikhunjini esilungele insimbi encibilikisiwe. Umphumela? Izingxenye zomumo oseduze nenethi ezinezindawo ezibushelelezi, azikwazi ukubekezelela izinto eziqinile, nezimfuneko ezisalungiswa eziqanda. Kodwa akuzona zonke izinsizakalo zokuphonsa i-wax eziletha imiphumela engaguquki. Sikubona ngokuphindaphindiwe: amakhasimende ashintsha abahlinzeki ngemva kokuthola ukulingwa okunokuncipha okuncane ezindaweni ezibucayi zokuvala, ukwakheka okusanhlamvu okungaguquki kuwo wonke amaqoqo e-AMS 5387, noma ukonakala okungaphezulu okudinga ukukhishwa kwesitoko se-CNC ngo-30% ngaphezu kwalokho obekuhleliwe.
Imbangela ayikona ngaso sonke isikhathi ukusakaza okungalungile—kuwukungaqondi kahle phakathi kwenhloso yokuklama, ukuziphatha kwezinto ezibonakalayo, nokulawula inqubo. Isibonelo, inkontileka ye-alloy esekelwe ku-T800 ye-cobalt engu-12.4% ngaphezu kuka-316 engenasici ngesikhathi sokuqina. Isevisi yokukhipha i-wax ngaphandle kwezihibe zempendulo ye-metallurgical izokhiqiza amaphethini abukeka kahle ku-CAD kodwa akhiphe izindlu zamasilinda asontekile ngemva kokupholisa. Ithimba lethu liqinisekisa yonke idizayini yephethini ngokumelene nedatha yokulingisa eshisayo—futhi lilungisa isango, ukukhuphuka, nokuqina kwegobolondo ngaphambi kokuthela kokuqala.
Lapho ukuhlanganiswa okuqondile kususa amaphuzu okuhluleka afihliwe
Iningi labasunguli linikeza ukulingisa ezitolo zemishini zezinkampani zangaphandle. Lokho kudala izendlalelo zengcuphe ezintathu: ukukhukhuleka okulinganayo phakathi kokulingisa nomshini, ukulahleka kokulandeleka kwempahla, kanye nempendulo ebambezelekile mayelana nokukhubazeka kwephethini. Sisebenzisa kokubili ukutshala imali kanye nomshini we-CNC we-5-eksisi ngaphansi kophahla olulodwa oluqinisekisiwe lwe-ISO 9001 e-Qingdao. Lapho indlu yephampu ye-piston ifika ivela esithandweni somlilo, iya ngqo ku-Zeiss Contura G2 CMM yethu—hhayi endaweni yokungena. Sikala ubukhulu be-cast-cast, sibuqhathanise namamodeli abikezelwe okuncipha, futhi silungise iphethini elandelayo ye-wax phakathi namahora angu-48.
- Izingxenye ze-AMS 5387 ze-cobalt alloy zithola isisombululo *ngaphambi* komshini—hhayi ngemva—ukuze kuzinzise i-microstructure futhi kuvinjwe ukuhlanekezela ngesikhathi sokugaya.
- Konke ukukhishwa kwensimbi kuthola ukuhlaziywa okugcwele kwe-spectral nokuhlolwa okuqinile; imibiko ihlanganisa amandla esivuno sangempela ngokumelene ne-ASTM A958 spec
- Ukuqedwa kwendawo kulawulwa ngasekugcineni: ukwakheka kwegobolondo le-ceramic kuthinta amanani e-as-cast Ra, okunquma ukuthi sisebenzisa i-shot peening noma i-electropolish post-machining.
Lokhu akulula-ukulawula okuqhutshwa yi-physics. I-winch center shaft roller eyenziwe nge-ductile iron kufanele igcine ubulukhuni obungu-285 HB kuwo wonke umjikelezo wayo. Uma ukulingisa kuphola ngokulinganayo, ukukhanda kuveza izindawo ezithambile. Ukuqapha kwethu isithando somlilo kufaka ama-gradients okushisa njalo ngemizuzwana engama-90 phakathi nokunyakaziswa. Sihlobanisa lawo malogi namamephu wokuqina avela kuzo zonke izingxenye eziqediwe. Leyo datha ibuyela ekubekweni kwephethini ye-wax ngaphakathi kwesikhunta.
Ukuqinisekiswa komhlaba wangempela-hhayi nje ukuthobelana
Abanye abahlinzeki bafaka ohlwini “i-ISO certified” kanye “ne-CNC iyakwazi” kodwa abanalo ulwazi olufakazelwe lohlelo lokusebenza. Asigcini nje ngokuhlangabezana nezindinganiso—sivivinya ngezindlela zokwehluleka. Amapulagi ethu e-cobalt alloy adlule imijikelezo engu-14,000 endaweni yokulingisa uwoyela negesi ngaphambi kokukhishwa. Amavalvu okucindezela ahlolwe nge-hydrostatically ku-1.5 × ingcindezi elinganiselwe, bese ehlolwa kusetshenziswa udayi ongenayo kanye nokuhlolwa kwe-ultrasonic ukuze kunqanyulwe indawo engaphansi komhlaba. Lezi akuzona izengezo ozikhethela zona. Zakhelwe ekuhambeni komsebenzi wethu wesevisi yokuphonsa ngoba amakhasimende athumela lezi zingxenye kumasistimu abalulekile ezokuphepha.
Futhi sihlaba umkhosi lokho *okungakwazi ukusakazwa* ngendlela enokwethenjelwa—ngaphambi kwesikhathi. Ikhasimende lake lathumela umdwebo wensimbi engagqwali engu-2.3 mm eneziphaseji zangaphakathi ezimbalwe. Onjiniyela bethu basebenzise ukulingisa kokugeleza kuphethini ye-wax futhi bahlonza ukugeleza kwensimbi okunyakazayo okungabangela ukuvala okubandayo. Esikhundleni sokucaphuna ngokungaboni, siphakamise indlela ehlanganisiwe: ukutshala imali-sakaza indikimba eyinhloko, bese kuba umshini we-CNC izici zangaphakathi. Lokho konge u-37% wezindleko eziphelele uma kuqhathaniswa nokuzama ukuphoqa ijiyomethri ngokuphonsa kuphela.
Ukukhetha uzakwethu wesevisi yokuphonsa i-wax
Buza imibuzo emithathu ngaphambi kokwenza:
- Bangakubonisa imibiko ye-CMM yenani lakamuva lebanga lakho lengxubevange—hhayi amasampuli ajwayelekile?
- Ingabe benza ukuqinisekiswa kwezinto ezingenayo *futhi* bagcine amakhuphoni aphathekayo kukho konke ukushisa ukuze aphinde ahlolwe?
- Uma ubukhulu buwela ngaphandle kokubekezelelana, ingabe babuyisela ingxenye enesici nezithombe ezinezichasiselo kanye nokuhlaziywa kwembangela—noma bavele bakhiphe enye?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uphendula ngoyebo bobathathu. Sibhala phansi zonke izinyathelo zokuhlola, sifaka kungobo yomlando wonke amarekhodi okulinganisa, futhi sabelane ngamadokhumenti okulandeleka okugcwele namakhasimende. Isevisi yethu yokukhipha i-wax isekela i-prototype ihamba kancane njengezingcezu ezingu-5 futhi ukukhiqizwa kufinyelela kumayunithi angu-5,000 ngonyaka-ngaphandle kokushintsha amapharamitha amathuluzi noma inqubo. Ngoba ukungaguquguquki akuyona inhloso. Yisisekelo.
Uma iphrojekthi yakho elandelayo idinga ubuqotho bobukhulu ngaphansi kwengcindezi ephezulu, ukumelana nokugqwala kumidiya enamandla, noma impilo yokukhathala engaphezu kwemijikelezo engu-10⁷—qala ngesevisi yokukhipha i-wax ephatha insimbi njengobunjiniyela, hhayi ubuciko. Ukunemba kuqala lapho ingcina incibilika khona.
