Reba, iyo abantu benshi bumvise 'MIM icyuma gitera inshinge', batekereza ko ari amasasu yubumaji yo gukora ibyuma bigoye bihendutse. Udutabo twumva nkaho usuka ifu mumashini hanyuma ugasohoka igice cyuzuye. Nicyo gitekerezo kinini. Mubyukuri, ni inzira yo guhora kumvikana no guca imanza. Ntabwo buri gihe ari igisubizo cyiza, kandi kumenya igihe cyo kugenda ni ngombwa nko kumenya kuyobora akazi. Nabonye imishinga myinshi yananiwe kuko umuntu yagerageje guhatira MIM aho itari iyariyo, ashukwa nisezerano ryubunini bwinshi na net-shusho.
Imbyino Yibanze: Kugaburira, Ibikoresho, no Gukina Urusimbi
Umutima wa MIM yo gutera inshinge ntabwo ari kubumba-ni ibiryo. Kubona iyo mvange yifu yicyuma na binder neza neza ni alchemy kuruta siyanse. Gutandukana kwa 2% mu gupakira ifu birashobora gusenya urwego ruhamye nyuma yo gucumura. Twigeze gushakisha ibiryo bisanzwe 17-4 PH biva mubucuruzi bushya kubikoresho byo kubaga. Yabumbabumbwe neza, ariko mugihe cyo gutesha agaciro, sisitemu ya binder yaracitse, bituma igice cyibiza gitemba mu itanura. Iri ryari isomo rya $ 40k ibikoresho byo kwiga: ntuzigere wibwira ko ibiryo ari ibicuruzwa.
Kandi ibikoresho ... ni inyamaswa itandukanye nuburyo bwo gutera inshinge. Urimo gushushanya 20-25% kugabanuka, ariko ntabwo ari isotropic. Irahinduka hamwe na geometrie igice, uburebure bwurukuta, ndetse nuburyo ibiryo bitembera mu cyuho. Twari dufite agace ka sensor yo mu kirere, igice kirekire, cyoroshye. Amafuti ya mbere yavuye mubibumbano neza, ariko nyuma yo gucumura, byafashe nk'igitoki. Gukosora ntibyari mu itanura; byari mukongeramo ibintu byoroshye, birwanya-intuitive curvature kumurongo wububiko ubwabwo. Ntabwo urimo gushushanya igice, urimo gushushanya verisiyo yagoretse mbere yo gucumura.
Gucumura niho icyuma gikora rwose, kandi ni intambwe ndende. Imiterere yubushyuhe, ikirere (hydrogen, azote-argon ivanze), nigihe byose birakomeye. Byihuta cyane igipimo cyinshi, urabona binder guteka. Hasi cyane temp, usigaye ufite imiterere, idakomeye. Ndibuka icyiciro cyicyuma gifunga ibyuma kumukiriya uremereye. Batsinze igenzura ryose ryerekanwa kandi ryananiwe ariko birananirana mugupima umurima - kuvunika kuvunika. Intandaro? Ubushuhe bwa termocouple mu itanura ryacumuye bwaremye ahantu hakonje 30 ° C. Ibice byasaga nkibyuma ariko ntabwo byigeze bihurizwa hamwe. Nicyo gice cyamayeri cya MIM; inenge irashobora gushyingurwa byimbitse muri microstructure.
Aho MIM imurikira (Kandi aho itagaragara)
Ni ryari kubumba ibyuma birumvikana? Nibyiza kubice bito, bigoye cyane, binini cyane byaba ari ubwicanyi kumashini. Tekereza guteranya ibikoresho hamwe nibice byimbere, guhuza indege nyinshi, cyangwa ibice bifite inkuta ninkuta zoroshye. Intsinzi ya kera yari titanium alloy igizwe nibikoresho byubuvuzi byambara. Kubikora bivuye mubikomeye byari bihenze kandi birasesagura. MIM yatugejeje kuri 95% net net, dukeneye gusa bore irangiza-yakozwe. Ingano (200k + buri mwaka) yashimangiye NRE yo gukoresha ibikoresho no gutezimbere.
Ariko dore impande zombi. Niba igice cyawe cyoroshye-umwanya wibanze cyangwa igitereko kiringaniye - wibagirwe MIM. Kashe cyangwa CNC bizaba bihendutse kandi byihuse. Na none, niba ukeneye ibikoresho bya mehaniki bikabije, nkimbaraga zanyuma zingirakamaro zibyakozwe, MIM irashobora kugwa mugufi. Inzira yo gucumura, mugihe irema hafi-yuzuye, iracyasiga microstructure itandukanye nicyuma gihimbano. Tugomba kuvugana n'umukiriya kugirango dukoreshe MIM kubintu bikomeye, bigira ingaruka zikomeye zo gukata pin mugikoresho cyo hasi. Ibyago byo gukosorwa bidasanzwe ntibyari bikwiye, kabone niyo byagenzurwa na MPI 100%.
Gukora Intoki: Impamvu Nyuma yo Gutunganyirizwa Akenshi Ataganira
Aha niho net-imiterere isezerana ikubita ukuri. Ibice byinshi bya MIM bikenera ibikorwa bya kabiri. Umwobo urashobora gukenera guhindurwa muburyo bwo kwihanganira H7, cyangwa hejuru yikimenyetso gishobora kuba hasi. Niyo mpamvu ubushobozi bwa MIM iduka ari byiza gusa nkubufasha bwayo bwo hasi. Nakoranye nabafatanyabikorwa nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Amateka yabo ntabwo arimo MIM; ni muri gushora imari kandi neza Imashini ya CNC. Ibyo ni ngombwa. Babona ko igice cyacumuye atari iherezo. Bashobora kureba igice cya MIM bakamenya datum yogukomeretsa kugirango ikoreshwe, uburyo guhangayika gusigaye bishobora kugira ingaruka ku kugabanuka, kandi niba ikintu cyagezweho neza mubibumbano cyangwa kuri lathe nyuma. Kurukurikirane rwa cobalt-chromium alloy valve plaque twakoze, icyifuzo cyo kureshya cyari kirenze ubushobozi bwo gucumura. Itsinda rya QSY ryatanze igitekerezo cyoroshye cya MIM gifite ububiko burenze, hanyuma bahita basobanura neza. Igisubizo cyari cyiza, kandi ikiguzi cyari gito ugereranije no kugerageza kwihanganira ibyaha bidashoboka.
Guhitamo ibikoresho bigira uruhare runini hano. MIM ikora ibintu byinshi - uhereye kubisanzwe ibyuma Kuri Exotic nikel. Ariko machinability nyuma yo gucumura iratandukanye cyane. Imashini ya 316L idafite ibyuma byoroshye. Tungsten yacumuye? Iyo ni inkuru itandukanye, isaba ibikoresho byihariye nibipimo. Ugomba gutegura urwego rwose rwo gukora, ntabwo ari intambwe yo kubumba gusa.
Kunanirwa n'amasomo bagushiraho ikimenyetso
Wiga byinshi mubisakuzo kuruta igitabo. Kera, twakurikiranye umushinga kubice bigoye bya aluminium MIM. Ku mpapuro, byari byiza: imiyoboro ikonje cyane, amajwi menshi. Ariko ifu ya aluminiyumu ni pyrophorike, igice cyayo cya oxyde ninzozi mbi yo gucumura, kandi kugabanuka birashoboka cyane. Umushinga watwaye amezi nibice bitabarika mbere yuko tuyica. Umukiriya yahinduye a Igikonoshwa inzira kuriyo mavuta yihariye na geometrie. Byari kwibutsa guca bugufi ko MIM ari agace ka powder metallurgie, ntabwo isimburwa kwisi yose kubindi buhanga byose bikora.
Ubundi buryo bworoshye bwo kunanirwa ni kwisiga. Kubakoresha ibikoresho bya elegitoroniki yimiturire, ubuso bwacumuye bwari bufite gato, orange-peel. Byari byiza, ariko muburyo bwiza ntibyemewe kubisabwa. Gusiga byari bihenze cyane. Twagombaga guhindura ingano ya powder ingano yikwirakwizwa hamwe nikirere cyacumuye kugirango tugere ku buso bworoshye neza buva mu itanura, byongeweho ikiguzi nigihe cyigihe. Ikiruhuko? Kurangiza isura nibisobanuro bigomba kuganirwaho mugitangira, ntabwo ari ibitekerezo.
Icyerekezo gifatika: Kwishyira hamwe no Gusuzuma Inyangamugayo
Kujya imbere, agaciro ka MIM yo gutera inshinge ntabwo iriho mu cyuho. Imbaraga zayo ziri mubikoresho bimwe muburyo bwagutse bwo gukora. Amaduka ashobora gutanga MIM kumurongo wibanze, Imashini ya CNC kubintu bikomeye, kandi birashoboka ndetse gushora imari kuri prototypes nini, itanga agaciro nyako. Iremera guhitamo inzira zinyangamugayo zishingiye kubikenewe byukuri - geometrie, ibikoresho, ingano, nigiciro - ntabwo bishingiye gusa kubikoresho biri munzu.
Kuri ba injeniyeri bategura igice gishya, inama zanjye zeruye niyi: fata numufatanyabikorwa wawe mukora icyiciro. Mubazane igishushanyo. Ba imbere kubyerekeye amajwi n'ibikenewe mu mikorere. Umufatanyabikorwa mwiza, umwe ufite ibishingwe byimbitse no gutunganya imizi nkuko ubibona kuri QSY, azakubwira niba MIM ikwiye cyangwa niba ukorerwa neza na a Igikonoshwa in icyuma cyangwa fagitire yimashini ya ibyuma. Birashoboka ko babibonye byose. Intego ntabwo ari ukugurisha kuri MIM; ni ukubona igice cyizewe, cyigiciro cyinshi. Rimwe na rimwe, iyo nzira iganisha neza binyuze mumashini itera inshinge. Akenshi, sibyo. Kumenya itandukaniro nicyo gitandukanya abasomyi b'agatabo nabantu bamaranye imyaka bakura impumuro y'amatungo ashyushye hamwe n'itanura ryacanwa mumyenda yabo.
