Iyo wunvise 'ibyuma bitagira ibyuma bidafite inshinge' cyangwa MIM, ikibanza gihita gihora kijyanye no kugorana no gushushanya. Ariko kuba maze igihe gito, nsanga inkuru nyayo itari mu gatabo keza; biri mubisobanuro birambuye byo gukora 17-4PH bracket ifata icyiciro cyo kwihanganira 0.005 nyuma yicyiciro, cyangwa kuki igice cyagenewe gukora imashini cyananirana cyane iyo uhinduye MIM. Hano hari imyumvire itari yo ivuga ko MIM ari inshinge nziza ya pulasitike ibumba ifu y'icyuma - sibyo. Ibyiciro byo gusiba no gucumura bizana impinduka zishobora kwicisha bugufi ndetse na injeniyeri yuburambe. Ninyamanswa ivanze, yicaye hagati yo gutara no kuyitunganya, kandi isaba kubaha igitabo cyihariye cyihariye.
Imbyino yibikoresho: Ntabwo ari ibyuma gusa
Ntushobora kuvuga ibyuma bitagira umwanda hanyuma ukabyita umunsi. Kuri kubumba ibyuma, ifu iranga nibintu byose. Ingano yubunini bwo gukwirakwiza, imiterere, no gutembera hamwe na sisitemu yo guhuza gukora cyangwa kumena igice. Twakoze akazi hamwe na 316L na 17-4PH ahanini, ariko no muri ayo manota, utanga ifu itandukanye arashobora guhindura ibintu byose bigabanuka. Ndibuka umushinga wibikoresho byo kubaga aho spec yahamagaye 316L yo kurwanya ruswa. Ibyiciro bike byambere byacumuye neza, ariko imbaraga zumunaniro zari zashize. Hindura, ibirimo ogisijeni iri mu ifu, ikintu tutari twarasuzumye bihagije, cyari hejuru cyane, biganisha ku minota. Twahinduye ifu ya gaz-atomize ifu ifite spike ikaze, irabikemura. Nibisobanuro bitandukanya prototype nibicuruzwa byiteguye.
Aha niho kugira amateka mugukora ibyuma byagutse ni ntagereranywa. Gukorana numukunzi nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ufite imyaka ibarirwa muri za mirongo mu gushora imari hamwe na CNC gutunganya ibyuma bitagira umwanda hamwe nudukoryo twihariye, urabona ibyo bintu byashinze imizi. Ntabwo ari ugukanda ifu gusa; basobanukiwe nuburyo ibyuma bitwara munsi yubushyuhe na stress biturutse kumpande nyinshi zikora. Ubwo bumenyi bwambukiranya amakuru buramenyesha imyitozo ya MIM - kumenya, nkurugero, uburyo 304 yacumuye ishobora kwitwara ukundi mugikorwa cya CNC cyakurikiyeho ugereranije nabakinnyi bayo.
Icyiciro cyo gukuraho binder nicyicanyi cyicecekeye. Byihuta cyane, kandi ubona uduce cyangwa ibisebe; gahoro cyane, kandi urimo kwica itanura ryanyu nigiciro. Kubyuma bidafite ingese, kugenzura karubone mugihe cyo kwishyura ni ngombwa. Kureka ibisigazwa byinshi bya karubone, kandi ukagira ingaruka kumurwanya wa ruswa - niyo mpamvu wahisemo kutagira umwanda. Twize ibi inzira igoye kumushinga hakiri kare clip ya marine. Ibice byatsinze igenzura ariko byananiye ikizamini cyoroshye cyo gutera umunyu. Intandaro yabyo yari cycle ituzuye yumuriro wasize karubone inyuma, chromium igabanuka. Ivugurura, ibyiciro byinshi byo gukuraho byakosowe. Nibutsa ko muri MIM, utarimo gukora ibyuma gusa; urimo kwiyubaka neza microstructure yayo uhereye kumashanyarazi.
Igishushanyo cya MIM, Ntabwo ari Imikorere gusa
Ngiyo ngingo nini yo guterana amagambo hamwe nabashakashatsi. Batanga igice cyagenewe gutunganya cyangwa gushora imari kandi bategereje ko MIM izabikora gusa. Ntabwo ikora gutya. Ubunini bw'urukuta rumwe ni ubutumwa bwiza. Twari dufite umukiriya ushimangira kuri flange ifite umubyimba mwinshi kandi unanutse, radiyo. Igice cyafashe nk'icyayi cy'ibirayi mugihe cyo gucumura kuko kugabanuka gutandukanye kwari kwinshi. Tugomba gusubira inyuma, tuganira kongeramo gussets ntoya no kubyimba gato fins, byongeramo uburemere buke ariko bikiza geometrie yose. Igikoresho cyagombaga guhinduka, birumvikana. Nubufatanye, rimwe na rimwe itera, kubyina.
Ibiranga nkibisobanuro hamwe nudodo twimbere niho MIM imurikira, ariko bisaba ibikoresho byubwenge. Gushyira pin kumurongo kubice bidafite umwanda biroroshye kuruta kuri plastiki - urashobora gusiga ibimenyetso bigaragara cyangwa ugatera no guhindura igice cyicyatsi. Ndibuka ibikoresho bito bifite amenyo yumutwe aho pine ya ejector yagombaga gushyirwa mumaso yibikoresho. Twarangije gukoresha sisitemu, ibyiciro byinshi byo gusohora no gusya pin kugeza indorerwamo kurangiza kugirango tubuze ikimenyetso. Igiciro cyibikoresho cyazamutse, ariko igiciro cyigice nigikorwa nticyagereranijwe ugereranije nibindi bikorwa.
Ikindi kintu gifatika: imfuruka. Nibyo, ukeneye umushinga muto ugereranije no gushushanya inshinge gakondo, ariko uracyakeneye bimwe, cyane cyane kubyobo byimbitse. Kugerageza kwikuramo umushinga wa zeru kugirango uzigame kumashini ya kabiri bishobora kuvamo ibice bifatanye nigikoresho cyangwa kubona amanota mugihe cyo gusohora. Nubukungu bwibinyoma. Intego ya ibyuma bidafite ingese ni net-shusho, ariko net bivuze ko isohoka mu itanura ryacuzwe ryiteguye gukoresha. Akenshi, kubintu bikomeye, CNC yoroheje cyangwa gucukura biracyakenewe. Ibyo ntabwo ari kunanirwa kwa MIM; ni uburyo bwa pragmatic hybrid. Isosiyete nka QSY, ifite ubushobozi bwa CNC ihuriweho, ikemura iyi mitekerereze nta nkomyi - babona ops ya kabiri atari inzira yihariye ahubwo ni intambwe yanyuma mubikorwa bya MIM.
Icyaha cyo gucumura: Aho Ubumaji (no Kubabaza Umutima) Bibaho
Ibintu byose mbere yo gucumura ni ukwitegura gusa. Nicyiciro aho igice cyirekuye, cyijimye gihinduka ikintu cyuzuye, cyuma cyumvikana. Kubyuma bidafite ingese, kugenzura ikirere nibyingenzi. Ubusanzwe ukoresha hydrogen, argon, cyangwa vacuum. Hydrogen ninziza yo kugabanya okiside yo hejuru no gusukura igice, ariko ugomba gucunga neza ikime neza. Kumeneka kwinjiza umwuka wa ogisijeni cyangwa azote birashobora kwangiza umutwaro wose w'itanura.
Uburinganire bwubushyuhe nubundi inyamaswa. Guhinduka A +/- 10 ° C kuruhande rwitanura birashobora gutuma habaho itandukaniro rya 0.2% mugabanuka. Ku gice cya 50mm, ibyo ni 0.1mm-bihagije kugirango usibe icyiciro kugirango ushobore kwihanganira. Twashora imari mu itanura ryerekana hamwe na thermocouples nyinshi dusanga zone yacu nziza. Noneho, turapakira ibice bikomeye gusa muri iyo zone. Ibice bito byingenzi bigenda kumpera. Nibijyanye no gucunga umutungo utimukanwa wawe nka chessboard.
Igipimo cyo gukonja kigira ingaruka kumiterere yanyuma. Ku manota-akomera amanota nka 17-4PH, urashobora rwose kuvura igisubizo no gusaza ukurikije umurongo wo gucumura niba itanura ryanyu ryarashizweho. Nibyiza cyane, guhuza intambwe. Ariko kubona igihe-ubushyuhe-bwo guhindura umurongo neza kubice byihariye bya misa ni empirical. Twubatse isomero rito ryerekana imyirondoro yimiryango itandukanye. Ntabwo ari igitabo; ni iduka-hasi, ryanditse mubishushanyo mbonera na raporo za QC.
Iyo MIM Atari Igisubizo
Nkuko nizera inzira, ni ngombwa kumenya imipaka yayo. Kubumba ibyuma kurwana nibice binini cyane (muri rusange hejuru ya garama 250 kuri stainless) kandi binini cyane, ibice binini binini bikunda kurwana. Twigeze gusubiramo amagambo yoroheje, isa na sensor yubatswe hafi 2mm z'ubugari na 100mm hejuru. Ndetse hamwe nibikoresho bihuza gukonjesha no gucumura, ntidushobora gufata neza. Umukiriya yajyanye na kashe neza kandi ikora aho. Byari umuhamagaro mwiza.
Ibice byinshi-byuzuye byuburyo bwuburyo bwibanze bwindege zo mu kirere biracyakorwa neza muguhimba cyangwa gutunganya kuva kuri bilet. Imiterere ya isotropic ya MIM nibyiza, ariko kubisabwa cyane, ibisekuru byibikoresho byakozwe biracyakunzwe. Nyamara, kubice bitabarika mubikoresho byubuvuzi, imbunda, ibikoresho byinganda, hamwe nibikoresho bya elegitoroniki, MIM itanga uruvange rudasanzwe rwibintu bigoye, imikorere yibikoresho, nigiciro cyinshi. Nukutoranya intambara zawe.
Niyo mpamvu uburambe bwagutse butanga isoko. Niba winjiye mumaduka akora MIM gusa, barashobora kugerageza guhatira igice cyawe. Ariko ikipe nayo ikora gushora imari no gutunganya CNC, nkabantu kuri QSY, bizaguha isuzuma ryukuri. Bashobora kuvuga, Reba, kuri iyi geometrie nubunini, shell mold casting hamwe na CNC kurangiza birashobora kuba byiza cyane kuri wewe. Ibyo bifatika byubaka ikizere. Imyaka 30 yabo mugukina no gutunganya bivuze ko babona MIM nkigikoresho kimwe mumasanduku manini, ntabwo igikoresho cyonyine.
Gusya kwukuri-Isi: Ubwiza no Guhoraho
Gutangiza igice cya MIM ni ikintu kimwe; kubyara 500.000 muribo hamwe na CpK hejuru ya 1.33 nubundi. Kugenzura ibikoresho fatizo ni burimunsi: ifu yubunini buhoraho, binder batch viscosity. Mubikorwa-bigenzura kubice byicyatsi nuburemere bifata drift mbere yo gucumura. Ariko QC nyayo ibaho nyuma yicyaha. Dukora igenzura ryibarurishamibare ku bipimo bikomeye, kugenzura ubucucike (bigamije ubusanzwe> 96% bya theoretical for stainless), hamwe na metallurgie yuzuye burigihe - ibizamini bya tensile, ubukana, kugenzura ruswa. Ntabwo ari ibiganiro.
Isesengura ryananiwe ni igice cyakazi. Njye namaze amasaha munsi ya microscope ndeba igice cyacitse. Byari ibinure byacumuye, gushiramo kwanduzwa, cyangwa ibyago byo guhangayika biturutse ku nenge yabigenewe? Buriwese afite igikumwe gitandukanye. Ikibazo cyagarutsweho hakiri kare ni igice gikomeye cyananiwe guterana. Ibice byanyuze hejuru. Amaherezo, yabikemuye ku kibazo cyo gukemura - abakozi bajugunyaga amabati y'ibice byacumuye, bigatuma uduce duto duto twaje gukwirakwira. Gukosora ntibyari mubikorwa; kwari ugushira ifuro mumabati. Isomo: inzira ntabwo irangirira ku ziko.
Kurangiza, gutsinda ibyuma bidafite ingese ni ibijyanye na sisitemu yo gutekereza. Nubukwe bwibikoresho siyanse, gushushanya imashini, gukora ibikoresho, gukora amashyuza, no kugenzura ubuziranenge bukomeye. Ntabwo ari amasasu. Ninzira isaba, ishimishije, kandi ikomeye cyane mugihe usobanukiwe nururimi rwayo kandi wubaha amategeko yayo. Ibigo bitera imbere muri byo, kimwe nabafite uburambe bwimbitse shingiro mubucuruzi bwibyuma bifitanye isano, nibyo bitagurisha ibice gusa - bigurisha ibisubizo byizewe, byakozwe mubuhanga.
