Xa iinjineli zidinga iindawo zentsimbi ezibambe ukunyamezelana okuqinileyo, ukuxhathisa ukunxiba okugqithisileyo, kwaye uphile kuxinzelelo oluphezulu lwehydraulic okanye ioyile kunye negesi kwindawo-abanelisekanga "kufutshane ngokwaneleyo." Bafuna a i-mim powder metallurgy factory ngoqeqesho oluqinisekisiweyo lokuphatha ii-cobalt-nickel superalloys, hayi nje enye eqhuba inkqubo. Kodwa nantsi into efunyanwa ngamaqela amaninzi kuphela emva kokulibaziseka okanye ukusilela kwenqaku lokuqala: I-MIM ayitshintshi ngokufaka utyalo-mali-okanye umatshini weCNC. Yinkqubo yendalo echanekileyo. Kwaye umahluko wokwenyani awukho izixhobo phantsi. Yindlela isayensi yezinto eziphathekayo, utoliko lwe-GD&T, kunye nenkqubo ye-metrology elukwe ngayo kunye.
Kutheni i-"MIM Powder Metallurgy Factory" ihlala iligama elilahlekisayo lokukhangela
Abathengi abaninzi bachwetheza "i-mim powder metallurgy factory" kuGoogle belindele ukuveliswa kwe-MIM ye-turnkey-kwaye bahambe bedidekile. Ngoba? Kuba ukugqwesa kwe-MIM yokwenyani kufuna okungaphezulu kune-feedstock kunye ne-sintering furnaces. Ifuna inkangeleko ye-alloy-specific sintering profiles, i-kinetics elawulwayo yokubopha kwiijiyometri ezintsonkothileyo, kunye nembuyekezo ye-post-sinter dimensional eqinisekisiweyo kumakhulu amaqashiso. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye sabona abathengi bethumela imizobo elungele i-MIM-kuphela ukufumana i-AMS 5387 ye-cobalt alloy nozzle ijike nge-0.08 mm emqaleni emva kokucoca. Ukulungiswa kwakungekho ixesha lokujikeleza ngokukhawuleza. Yayilungisa kwakhona imigangatho yoxinaniso oluluhlaza kunye nokuhlengahlengisa amaxabiso ethambeka lesithando somlilo nge-1.2°C/min. Loo nqanaba lolawulo alihlali kwincwadana. Ihlala kwiimbali ezibhaliweyo zobushushu, ukulandeleka kwinqanaba le-batch, kunye neenjineli eziqhube i-17,000+ imijikelo ye-sinter kwi-T800-grade feedstock.
Apho i-MIM ingena khona-kwaye apho ingekho khona-kwiiNqanawa zezoShishino ezichanekileyo
I-MIM iyakhanya xa ubunzima bejometri budibana nobunzima obusebenzayo. Cinga i-piston pump cylinder housings kunye neziteshi zokuhamba zangaphakathi, imizimba yevalve yoxinzelelo eneendawo zokuhlala ezidibeneyo, okanye i-winch center shaft rollers ezifuna zombini ubunzima bomhlaba> i-62 HRC kunye nobunzima obuphambili> 120 J. Ezi azikho ubucwebe okanye iinxalenye ze-electronics zabathengi. Ziyi-mission-critical components apho i-0.05 mm yokutenxa ibangela ukusilela kwintsimi. Kodwa iMIM ayisoloko iyimpendulo. Sihlala sicebisa ngokuchasene nayo kumacandelo afuna ubulukhuni obungaphaya kwe-40 mm amacandelo anqamlezayo-okanye ezo zidinga amandla e-isotropic tensile ngaphezulu kwe-1,450 MPa ngaphandle koxinzelelo lwesibini lwe-isostatic. Kwezo meko, indlela yethu ye-hybrid inikezela nge-ROI engcono: utyalo-mali olungaphambili lwe-preforms + ngokuchanekileyo ukugqiba kwe-CNC. Luhlanganiso oluthe nkqo-hayi ulwimi lokuthengisa. Kuthetha ukuba silawula ukuhamba okuziinkozo ngexesha lokusa, emva koko sitshixe imilinganiselo yokugqibela ngomatshini ohamba nentlanu usebenzisa iRenishaw-probed isixhobo sokuseta kunye nokuqinisekiswa kweCMM kumjikelo.
Izinto ezine ezingaxoxisiyo kwi-MIM ethembekileyo yokuFumana (Ixhaswa yiDatha yoMveliso yokwenyani)
- I-Feedstock eqinisekisiweyo + iBatch-Specific Sinter Profiles: Sifumana umgubo we-MIM kuphela kubaboneleli abaqinisekisiweyo be-ISO 9001 abaneengxelo ezipheleleyo ze-PMI. Iqashiso ngalinye lifumana igophe layo le-sinter-iqinisekisiwe nge-dilatometry kwaye yaqinisekiswa ngemephu ye-microhardness kuyo yonke imimandla ye-12 yebha yovavanyo.
- Kwinkqubo yeeSango eziDimensional: Akukho "uhlolo lokugqibela kuphela." Silinganisa iindawo eziluhlaza kwizigaba ezi-3 ezibalulekileyo: emva kokubunjwa, emva kokudibanisa, kunye ne-post-sinter ngaphambi kokunyanga kokushisa. Izinxaxhi>0.03 mm zibangela uphononongo lwengcambu ekhawulezileyo-hayi ukuphinda kusebenze.
- GD&T-First Engineering Review: Iqela lethu libonisa imingcipheko yokwenziwa phambi kokucaphula—njengeendlela zangaphantsi ezithitha isibophelelo, okanye iindonga ezibhityileyo (<1.2 mm) ixhomekeke kwi-warpage kwi-cobalt alloys. Sibuyisela imizobo enengcaciso enezinye iindlela, hayi nje “ayinakwenzeka.”
- Ukulandeleka ngokupheleleyo ukuya kutsho kwiNani loBushushu: Inxalenye nganye ihambisa ngesatifikethi esidwelise inombolo yobushushu, i-ID ye-sinter furnace, i shift yomsebenzisi, kunye ne-CMM ye-ID yengxelo. Akukho ngaphandle-nakwiprototypes.
Yintoni eza emva kwenqaku lokuqala-kwaye kutheni ibaluleke ngakumbi
Iifektri ezininzi zibethelela inqaku lokuqala. Bambalwa abayigcinayo kwiiyunithi ezingama-500. Kwiziko lethu leQingdao, uzinzo luqala ngezinto eziphathekayo. Sisebenzisana nokuphuhlisa iinkcukacha ze-feedstock kunye nababoneleli-ingakumbi kwi-alloys esekelwe kwi-T800-ukuqinisekisa ukuba umxholo we-oksijini uhlala ngaphantsi kwe-180 ppm kunye nokusabalalisa ubungakanani be-particle (D50) ibamba ± 0.3 μm iqashiso. Emva koko kuza uqeqesho lwenkqubo: umjikelo ngamnye we-sinter ufaka indawo yombethe, irempu yevacuum, kunye nexesha lokuhlala kwindawo ephezulu yobushushu. Ukuba iparamitha enye ikhukuliseka ngaphandle kwemida ye-SOP, yonke iqashiso ifumana i-100% yovavanyo lwe-ultrasonic-hayi isampuli. Yingakho umyalelo wethu wokuphinda u-PPM uhleli kwi-147, kungekhona i-1,200. Yiyo loo nto i-European hydraulic OEMs isicacisela iindibano zesiseko sempompo ezifuna ≤0.02 mm flatness ngaphezulu kwe-320 mm-ngaphandle kokugaya.
Ukujonga phambili, imfuno ayisiyiyo "i-MIM engaphezulu." Yenzelwe ukwenziwa kobuchule obuxutyiweyo: I-MIM cores eneendawo zokutywinwa ngoomatshini, i-sintered cobalt ifaka i-brazed kwizindlu ezingenasici, okanye iindawo ezikufutshane ze-MIM ezigqityiweyo nge-electrochemical polishing ye-ultra-low Ra kwiindlela zamanzi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. wakha obo buchule ngoku-hayi njengeeprojekthi ze-R&D, kodwa njengokuhamba komsebenzi okulungeleyo imveliso. Ukuba icandelo lakho elilandelayo lentsimbi elichaneke kakhulu lifuna ukungcungcuthekiswa komda, hayi nje ukuqhelana, qala ngamashiti edatha, hayi iincwadana. Emva koko buza oku: Ngaba banokukungqina oko—iqashiso ngeqashiso, ngokuyinxenye?
