Iyo wunvise 'MIM powder metallurgie', ishusho ihita iba muribi bice byiza, bito, bigoye ibice bizunguruka kumurongo wikora. Nicyo kiganiro cy'agatabo. Ukuri, uwo nabanye imyaka myinshi, ni akajagari, kurushaho, kandi mvugishije ukuri, birashimishije. Ntabwo ari ugukanda gusa no gucumura; ni imishyikirano ihoraho hagati yimyitwarire yibiryo, kwambara ibikoresho, nuburyo itanura ryumunsi. Abashya benshi, ndetse nabaguzi bamwe, batekereza ko ari isasu ryubumaji kumiterere iyo ari yo yose igoye, wirengagije inzitizi zifatika zo gupakira ibice hamwe na sisitemu yo guhuza. Itandukaniro riri hagati yimyumvire nukuri kwukuri niho umurimo nyirizina ubera.
Imbyino Yibanze: Kugaburira hamwe nigikoresho
Umutima wa MIM ntabwo ari ifu yicyuma yonyine; ni ibiryo - ibyo bivangavanze bya poro nziza na sisitemu yo guhuza ibintu byinshi. Kubona ubwo bwenge neza nubuhanzi burenze siyanse rimwe na rimwe. Urashobora kugira gaz-atomize nziza ya 17-4PH ifu, ariko niba ifumbire ya binder ihagaritswe nigice, uzabona ibibazo mubibumbano, nka jetting cyangwa ibyuzuye bituzuye, bigaragara mugihe cyo kwishyura. Ndibuka umushinga wibikoresho byo kubaga hinge aho twarwanije ibimenyetso byo kurohama ibyumweru. Nyirabayazana ntabwo yari ubushyuhe cyangwa umuvuduko, ahubwo ni ukudahuza gato muri pellet yibiryo bivangwa nuwaduhaye isoko. Yadusubije kuri kare imwe.
N'ibikoresho. Abantu basuzugura imyambarire kuri MIM. Kuberako urimo gutera inshinge, ibintu byingenzi, cyane cyane ayo menyo meza kumashanyarazi ntoya kugirango akoreshwe neza, arashobora guhita yihuta kuruta kubumba inshinge. Ugomba guteganya kubyo, kubaka mumafaranga, cyangwa kwerekana ibikoresho bikomeye ibyuma biva. Nigiciro gikunze kubura mumirongo yambere.
Aha niho umufatanyabikorwa ufite amateka yimbitse yibintu. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nkurugero, izana uburambe bwibyuma byuburambe kuva gushora imari no gutunganya kumeza. Mugihe urubuga rwabo nyamukuru kuri tsingtaocnc.com burambuye akazi kabo hamwe na alloys, ubwo bumenyi shingiro nibyingenzi. Iyo ukemuye superalloys yashongeshejwe, urumva imiterere yintete nimpinduka zicyiciro kurwego rumenyesha uburyo wegera gucumura a Ifu ya MIM metallurgie igice cyakozwe mumuryango umwe. Ninzira itandukanye, ariko intego za metallurgical zirasa.
Gukora-cyangwa-Kumena Icyiciro: Gutanga no gucumura
Nibisanduku byukuri byirabura bya MIM. Catalytic debinding, solvent debinding, ubushyuhe - buriwese afite imitego ye. Byihuta cyane, kandi ubona ibice cyangwa ibisebe nkuko binder igerageza guhunga. Biratinda cyane, nibicuruzwa byawe byinjira. Nabonye ibice biva mubushuhe busa busa neza, gusa kurwanira ibyago mu itanura ryacumuye kuko ibisigisigi bya binder byateje umuvuduko wimbere. Nibintu bibabaza umutima.
Gucumura niho amarozi n'iterabwoba bihurira. Ntabwo ushonga gusa; urimo korohereza ikwirakwizwa rya atome kurenga imipaka. Imiterere yubushyuhe, ikirere (hydrogen, azote, vacuum), nigihe nikintu cyose. Kubice bidafite ingese, dogere nkeya cyane cyangwa igihe cyo kumara umwanya muremure birashobora gutuma imikurire ikura cyane, ikica imiterere yubukanishi. Kubona inkunga yo gucumura neza kugirango wirinde kugoreka nubundi buhanga bwuzuye. Ntabwo ari ugushyira ibice ku isahani iringaniye.
Iyi sano isubira mubuhanga bwibintu. Amavu n'amavuko ya QSY muguterera ibinini bidasanzwe nka cobalt ishingiye kuri nikel ishingiye kuri nikel hano. Ibi nibikoresho byoroshye byo gucumura muri MIM. Kumenya ubushyuhe bwa solidus / fluidus, uburyo bakorana na karubone mugihe cyo gucumura, hamwe nubushuhe bwabo bwa nyuma bukenera uhereye kumikino ya casting biha itsinda intangiriro ikomeye. Irinda ikosa rya rokie ya classique yo gufata ifu yose yicyuma kimwe mumatanura.
Kwishyira hamwe hamwe na Secondary Operations
Ni gake cyane igice cya MIM kiva kumukandara wicyaha witeguye kohereza. Hafi buri gihe, ukeneye gutunganya kabiri. Iyi ni ingingo ikomeye. Kugabanuka kwicyaha, mubisanzwe 15-20%, birahanurwa ariko ntabwo bihuye neza. Noneho, urabishushanya, usize intera ikomeye nkurudodo cyangwa gufunga hejuru nkibicumuro byacumuye, cyangwa ugasiga ububiko kubikoresho byanyuma.
Hano niho ibikorwa bihagaritse byerekana agaciro kayo. Niba uwaguhaye MIM nawe afite ubushobozi bukomeye bwa CNC, nkibintu byingenzi bya QSY hamwe na serivisi zabo zo gutunganya CNC, ibisubizo biratangaje. Itsinda ryimashini rishobora kubwira itsinda rya MIM, Ibi biranga aho bigenda bihinduka kuri 0.05mm icyiciro-cy-icyiciro, dushobora guhindura ibikoresho cyangwa gucumura? Ubwo bufatanye bwimbere bukemura ibibazo byihuse kuruta kohereza ibice byicyatsi mumaduka yimashini yo hanze itumva neza inzira.
Nakoze kumubiri uhuza aho umwobo wa pin ukenera gukenera reaming post-sinter. Kugira imashini ikorerwa munzu, hamwe naba injeniyeri baturutse impande zombi bavugana burimunsi, byatwemereye guhindura uburyo bwo kugaburira amatungo gato kugirango tunonosore imashini tutabangamiye ubucucike. Yahinduye igice giteye ikibazo mubice byizewe.
Guhitamo Ibikoresho: Ntabwo ari Guhitamo Cataloge gusa
Guhitamo ibikoresho bya a Ifu ya MIM metallurgie igice ntabwo ari nko gutoranya kurutonde. Nibyo, ufite ibipimo: 316L, 17-4PH, Fe-Ni alloys. Ariko ifu ya lot-to-lot ihoraho, gukwirakwiza ingano (PSD), hamwe na ogisijeni bifite akamaro kanini. PSD ikaze irashobora gutanga gupakira neza hamwe no kurangiza neza ariko birashobora gutwara 30% birenze. Kubireba kwambara cyane, ushobora kuba ureba ibyuma byabikoresho nka M2, ariko rero ukuzenguruka kwawe no gucumura bigenda byiyongera cyane.
Aka ni akandi gace aho uburambe bwagutse butanga umusaruro. Isosiyete ifite ubuhanga bwo gutera ibyuma bidafite ingese hamwe nuduseke twihariye bizaba bifite ishingiro ryibikorwa byanyuma bisabwa. Ntabwo bishoboka cyane kurenza urugero-superalloy ihenze kumurimo wahinduwe 400-seri yahinduwe idashobora gukora, cyangwa ubundi. Basobanukiwe no kurwanya ruswa, ubushyuhe bwo hejuru cyane, kandi ntibambara nkimpapuro zamakuru gusa, ahubwo ni imyitwarire nyayo yisi kuva mumateka yabo. Urwo rubanza ni ntangere mugihe utanga inama kubijyanye no guhitamo ibikoresho MIM.
Kugenzura Ukuri: Iyo MIM Atari Igisubizo
Igice cyo kuba umunyamwuga muriki gice nukumenya igihe cyo kuvuga oya. MIM ni nziza cyane kubijwi byinshi, bigoye, bito-kugeza hagati. Ariko niba geometrie ari space yoroshye, hindukirira imashini. Niba ukeneye ubucucike bwuzuye, isotropic butagira ibisigisigi bisigara kuri indege yo mu kirere yuzuye ubunyangamugayo, urashobora kuba uri mubutaka bwo gushora imari. Niba ingano yumwaka ari ibice 10,000 gusa, igiciro cyibikoresho gishobora kwica ROI.
Nabaye mubice byimishinga aho twagerageje gusunika MIM mubisabwa ntibyari bikwiranye, bikururwa ningorabahizi. Imwe yari nini cyane yubatswe. Twashoboye kugoreka ibicumuro, ariko igice-igice gihoraho mumiterere yubukanishi nticyari gihagije kuburyo bwo gupima umunaniro wabakiriya. Twarangije kuvanga-dukoresheje MIM kuri hub igoye hanyuma dusudira ku kabari gakozwe kuboko. Cyakoze, ariko byari isomo ntarengwa ryimikorere.
Kurangiza, gutsinda Ifu ya MIM metallurgie ni hafi. Nigikoresho gikomeye mubikoresho byo gukora, ariko sibyo byonyine. Ibisubizo byiza biva mubafatanyabikorwa basobanukiwe nubutaka bwose - kuva ifu kugeza ibice byarangiye - kandi birashobora kugendana ibicuruzwa bifite amaso meza, pragmatism yo hasi. Ngiyo itandukaniro riri hagati yimyumvire ninzira yizewe yizewe.
