Lapho onjiniyela bayacacisa imboni yokubumba umjovo wensimbi izixazululo zokunemba okuphezulu, izingxenye ezicindezela kakhulu—ikakhulukazi kumasistimu asebenza ngamanzi, okokusebenza kawoyela negesi, noma imihlangano yephampu esindayo—ayivamile ukudinga amandla ajwayelekile. Badinga ukulawula okuqinisekisiwe phezu kwama-alloys e-cobalt-nickel, ukuphindaphinda kobukhulu ngaphansi kokuhamba ngebhayisikili okushisayo, nokulandeleka okugcwele ukusuka ku-billet eluhlaza ukuya engxenyeni eqediwe. Kulapho ukuhlanganiswa kwenqubo ejulile kubalulekile—hhayi nje “i-MIM,” kodwa ukuthi ukulingisa, ukukhanda imishini, ukwelashwa kokushisa, kanye ne-metrology kuhlangana kanjani endaweni eyodwa.
Kungani Ubuchwepheshe Bezinto Ezibalulekile Behlula Amakhathalogi Enqubo
Izitolo eziningi zokubumba umjovo wensimbi ziphatha izinsimbi ezingenasici noma izimpushana ezinengxubevange ephansi. Bambalwa abasebenza ngokuzethemba nge-AMS 5387 cobalt alloy noma ama-superalloys ebanga le-T800—izinto ezimelana nomshini, ezifuna umoya oqondile we-sintering, futhi zehluleke ngokuyinhlekelele uma i-microstructure ichezuka ngisho ngo-0.5%. Sibone ama-prototype amathathu ahlulekile avela kubahlinzeki baphesheya kwezilwandle abaphathe i-T800 “njengenye nje ingxubevange yezinga eliphezulu.” Eqinisweni, idinga amaphrofayili esithandweni esithandweni afanisiwe, izilinganiso zokupholisa ezilawulwayo ngemva kwe-sinter, nokuqinisekiswa kwe-CMM *ngaphambi* kokugaya okokugcina—hhayi ngemva kwalokho.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., umsebenzi we-cobalt-nickel akuyona isevisi yokwengeza. Ikhono eliwumongo. Isitezi sabo sokukhiqiza sisebenzisa imibhobho ye-AMS 5387 namapulaki ahambisana no-±0.015 mm GD&T—hhayi ngenxa yokubekezelelana okuqinile ephepheni, kodwa ngenxa yokuthi ama-metallurgists abo athuthukisa imijikelezo ye-sintering nabaphakeli bezinto ezibonakalayo. Amaqoqo angahluziwe afika nezitifiketi zokushisa ezigcwele; inkatho ngayinye icutshungulwa okubonakalayo ngaphambi kokucindezela. Akukho ukucabanga. Akukho ukuyekwa kwenqwaba.
Ukuhlanganisa Okuqondile Okuletha Ukuzinza Empeleni
Abakhiqizi abaningi bakhipha ukwelashwa kokuqeda noma ukushisa. Lokho kudala izikhala: ubuqotho baphezulu buyaphazamiseka ngesikhathi sokudlulisa, ukukhukhuleka kwe-dimensional kwenzeka phakathi kwemisebenzi, kanye nezitebele zokuhlaziya imbangela lapho umthwalo wemfanelo ufiphala kubathengisi bonke. I-QINGDAO QIANGSENYUAN ingumnikazi weketango eliphelele—ukusakaza kwe-investimenti, ukwenziwa kwemishini ye-CNC (i-axis engu-4 ne-5-eksisi), ukwelashwa kwe-vacuum, nokupholishwa ngogesi—konke ngaphansi kophahla olulodwa oluthobela i-ISO e-Qingdao.
Lokhu akukhona ukusebenza kahle kwethiyori. Ngezindlu zamasilinda ephampu ye-piston, kusho izici zomshini ngokuqondile ekulingiseni okuseduze *ngaphambi* kokudambisa ingcindezi—ukuqeda amaphutha okulungisa kabusha. Kumarola we-winch centre shaft yemoto yobunjiniyela, inika amandla ukujula kwekesi eliqinile elingu-1.2–1.8 mm nokungaguquguquki kwe-Rockwell C 58–62—okuqinisekisiwe nge-ASTM E18 ngayinye, akulinganiselwa. Sonke isiteji siphakela idatha kwesilandelayo: imibiko yokulinganisa kokubona iqalisa ukulungiswa kwe-offset yamathuluzi; Amalogi e-CMM axhumene namarekhodi e-thermocouple. Ukulandeleka akulotshiwe—kuyakhiwe.
Ukuqinisekiswa Komhlaba Wangempela Ngaphezulu Kwetiyetha Yezitifiketi
Izitifiketi zibalulekile—kodwa kuphela uma zibonisa umkhuba wangempela. I-ISO 9001 iyisiteki setafula. Yini ehlukanisa lokhu imboni yokubumba umjovo wensimbi ukuthi ukuqina kuhumusheka kanjani emiphumeleni yokusebenza. Lapho iklayenti laseYurophu lifuna ama-valve okucindezela alinganiselwe ngenkonzo eqhubekayo yamabha angu-420, iqembu alizange lenze ukuhlolwa okukhulu. Bahamba ngebhayisikili amayunithi angu-27 ngemijikelezo yengcindezi engu-15,000 ngenkathi beqapha ukuvuza ku-0.05 ml/min thresholds—besebenzisa amamitha okugeleza alinganiselwe, hhayi ukuhlola okubukwayo.
Baphinde babamba iphutha lokuklama kusenesikhathi: i-GD&T yoqobo yabiza ukuphela okuphelele ehlombe elivalayo, kodwa ingxenye yokukhwelana yayinemvume engokwemvelo. Onjiniyela babo bawuhlabe umkhosi ngesikhathi sokubuyekezwa komdwebo—futhi bahlongoza ukushintshela ekulawuleni iphrofayili-of-a-surface esikhundleni. Umphumela? Ukwehliswa okungama-22% kwezinga le-scrap phakathi nokukhiqizwa kwe-athikili yokuqala. Akuyona i-QA leyo. Lokho ukubambisana kobunjiniyela okushumekiwe.
Lokho Abathengi Empeleni Okudingeka Bakwazi Ngaphambi Kokuhlanganyela
Akuzona zonke izingxenye zensimbi ezinembayo ezizuzayo ku-MIM. Amajiyometri anezindonga ezincane eziyinkimbinkimbi ngaphansi kobukhulu bodonga obungu-0.5 mm? Yebo. Ivolumu ephezulu, izingxenye zesisindo esiphansi ezinezidingo eziqinile zokuzinza kokushisa? Yebo. Kodwa ngezisekelo ezinkulu zephampu ze-asymmetric ezidinga>200 MPa amandla aqinile nokushisela? I-Sand casting + ukunemba kwemishini iletha izindleko ezingcono ngengxenye ngayinye kanye nengozi ephansi.
I-QINGDAO QIANGSENYUAN ayiphusheli i-MIM njengesixazululo sendawo yonke. Inqubo yabo yokucaphuna iqala ngempendulo yokwenziwa—hhayi amashidi amanani. Bayabuza: Ithini imodi yokwehluleka? Uyini umjikelezo womsebenzi? Iyiphi i-dimension drive drives esebenzayo-hhayi nje efanelekile? Lokho kugxila kuchaza ukuthi kungani izinga labo lokuphinda liphindwe lidlula ama-78% kulo lonke elaseNyakatho Melika kanye nama-akhawunti ezimboni we-EU.
Uma uhlola a imboni yokubumba umjovo wensimbi ezingxenyeni zensimbi ezibaluleke kakhulu, beka phambili ubufakazi ngaphezu kwezincwajana. Cela amalogi okwelapha ukushisa ahlanganiswe nezingxenye ezithile zezinombolo. Cela imibiko ye-CMM ebonisa isimo sangempela ngokumelene nethiyori. Qinisekisa ukuthi ukuhumusha kwe-GD&T kuyenzeka yini *ngaphambi* kokusetshenziswa kwamathuluzi—hhayi ngesikhathi se-FAI. Bese uvakashela isikhungo. Buka ukuthi opharetha baphatha kanjani izikhala ze-cobalt alloy. Lalela ukuthi onjiniyela bakhuluma kanjani nge-microstructure—hhayi nje ubulukhuni.
Yileyo ndlela ukunemba okubikezelwa ngayo.
