Iyo abantu bumvise 'micro metal injing molding', cyangwa MIM ku gipimo gito, igitekerezo cyahise kijyanye nibice bito bidashoboka, bigoye. Nibyo, ariko kandi niho imyumvire ya mbere yibeshya. Ntabwo ari ugukora ibintu bito gusa; ni ugukora utuntu duto dukora mubyukuri, burigihe, kandi utarangije banki. Ikinyuranyo hagati ya prototype igaragara kuri slide ya microscope hamwe nigikorwa cyo gukora ibice 500.000 bikomeza guterana no gukora niho inkuru nyayo iri. Nabonye imishinga myinshi isitara mukuyifata nka verisiyo yagabanutse ya MIM isanzwe. Fizika, imyitwarire yibintu, imitekerereze yibikoresho - byose birahinduka.
Imbyino yibikoresho kuri Micro Scale
Gukorana nibiryo bya micro MIM ni umukino wumupira utandukanye. Urimo guhangana nifu nziza, akenshi munsi ya micron 10, kandi sisitemu ya binder iba ikomeye. Ntabwo ari ugufata ifu gusa; bijyanye nuburyo inyura mumarembo no kwiruka bishobora kuba ubugari bwa 0.15mm gusa. Twigeze kugira umushinga wibikoresho byo kubaga dukoresheje 316L ibyuma bidafite ingese. Ibiryo bisanzwe bisanzwe ntabwo byuzuza igice cyoroshye cyane. Tugomba gukorana cyane nuwatanze ibikoresho kugirango duhindure imvugo - byinshi byo guhinduranya ibishashara-polymer kugirango tubone uko bigenda neza, laminari. Nubwoko bwamaboko yibikoresho bitandukanya imishinga igenda neza niyatsinzwe.
Gutesha agaciro no gucumura bihinduka ibikorwa-wire. Hamwe nuduce duto duto, ibyago byo kugoreka cyangwa gusinzira mugihe cyizuba cyinshi. Ubushyuhe bwubushyuhe mu itanura bugomba kuba busobanutse neza. Ndibuka icyiciro cya cobalt-chrome orthodontic brackets aho twabonye ovalisation nkeya mumyobo yo gushiraho nyuma yo gucumura. Nyirabayazana? Ubushuhe butaringaniye mubushuhe bwigice kumurongo wa sinteri ikora micro-ihindagurika mubushuhe. Byaduhatiye kongera gushushanya ibice bya tray, ntabwo ari igice. Nibikorwa bya kabiri birambuye bitwara amasaha yubuhanga.
Aha niho uburambe hamwe nibisanzwe bidasanzwe, nkibyo ubona uhereye kumurongo muremure nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), biba ngombwa. Babaye mu myaka yo gukina no gutunganya. Ubwo bumenyi bwimbitse bwibintu-uburyo bushingiye kuri nikel cyangwa bushingiye kuri cobalt bitwara munsi yubushyuhe no guhangayika - bisobanura neza cyane iyo wimukiye muri micro MIM hamwe nuruvange rumwe. Ntabwo ari transfert itaziguye, ariko iyo mitekerereze ya metallurgical ni ntagereranywa. Urashobora kugenzura uburyo bwabo kubunyangamugayo bwibintu kurubuga rwabo, https://www.tsingtaocnc.com. Kubice bito, guhera kumutanga ubona ubumenyi bwibanze ni kimwe cya kabiri cyintambara.
Igikoresho: Aho Precision ihura na Pragmatism
Ifumbire ni byose. Kubice bya micro, ukunze gukoresha ibyuma bikomeye cyangwa ibyuma bya tungsten. Amashanyarazi, igishushanyo mbonera, imiyoboro ikonjesha - byose bikozwe ku gipimo gisaba EDM no gusya cyane. Ariko dore umutwe ufatika: kubungabunga. Agace k'umukungugu, akantu gato ka karuboni ya binder yubatswe muri micro-cavity, kandi umusaruro wawe uragabanuka. Twashyize mubikorwa gahunda yo gukora isuku ya ultrasonic yumurongo wibikoresho hagati yimikorere, byumvikana neza, ariko kubona inshuro ikwiye nigisubizo cyeza nta kwangiza ubuso bwakoronijwe byari inzira yo kugerageza-kwibeshya.
Irindi somo ryize inzira igoye: ntugakabye igikoresho kugirango ubigereho. Kera kare, twashushanyije ifu-cavity igizwe na cavites 64 kubikoresho bito. Igitekerezo cyari ukuzamura umusaruro. Ariko kuzuza ubudahwema mu mwobo wose byari inzozi; itandukaniro rito mubiruka biruka byabaye ingirakamaro. Twasubiye inyuma kuri 16-cavity igishushanyo hamwe na sisitemu yo kwiruka iringaniye. Ibicuruzwa byinjira mubikoresho byari bike, ariko umusaruro nigice gihoraho cyarashwe, bituma ubukungu muri rusange bumera neza. Rimwe na rimwe, muri micro MIM, bike ni byinshi.
Venting nubundi buhanzi bworoshye. Hamwe nubunini buke bwumwuka kugirango wimuke, guhumeka bidahagije ntabwo buri gihe bitera amafuti magufi. Irashobora gutera gutwika byoroheje (gukora inenge igaragara nyuma yo gucumura) cyangwa ibimenyetso byo gutindiganya bigira ingaruka kumpera. Twatangiye gukoresha ibyuma byinjizwamo ibyuma kugirango dushyire ahantu hakomeye, wari umukino uhindura umukino kubice bifite imbavu zoroshye.
Ikiraro Kuri Secondary Operations
Ni gake cyane igice MIM igice kiva mubwato bwicuza bwiteguye kohereza. Hafi buri gihe, hariho akazi ka kabiri. Iyi ni ingingo y'ingenzi akenshi idahabwa agaciro mugutegura umushinga. Isosiyete nka QSY, hamwe na hamwe Imashini ya CNC ubushobozi, ifite inyungu zitandukanye hano. Tekereza micro MIM igice ikeneye bore ikomeye ifatirwa kwihanganira +/- 0.005mm, cyangwa isura isaba kurangiza neza cyane. Inzira yo gucumura yonyine ntabwo izabigeraho.
Twari dufite ibice bya sensor ntoya aho igice cyacumuye cyari gikeneye icyerekezo kirenze ubushobozi bwibikorwa. Kugerageza kubigeraho ukoresheje gucumura byonyine byatumye igipimo kinini gisakara. Igisubizo kwari ugushushanya igice cya MIM hamwe n'amafaranga make yo gutunganya kuri iyo sura hanyuma ugakoresha uburyo busobanutse neza bwo gusya nyuma yo gucumura. Kugira ubuhanga bwo gutunganya murugo, nkuko QSY ibikora, byoroshya iki kiganiro. Amatsinda ya MIM nogukora arashobora gufatanya kuva mugice cyo gushushanya, bagahitamo ibiranga gukora binyuze muri MIM nibishobora kurangizwa hakoreshejwe imashini, guhitamo ibiciro kandi neza.
Ubu bufatanye ni ngombwa. Irinda kwerekana urutoki rushobora kubaho mugihe MIM ikorewe kumaduka imwe no gutunganya neza kurindi. Igice cyawe kigoretse mugihe cyo gucumura, ntabwo rero dushobora kwihanganira. Oya, ibikoresho byawe byo gutunganya birakoresha imihangayiko myinshi. Utanga isoko ahuriweho agabanya urwo rusaku. Kubintu bifite agaciro kanini, micro-verisiyo yibice bito, uku kugenzura kurangira-kurangira ntabwo ari ibintu byiza; ni ngombwa.
Kunanirwa kwisi-kwisi na Pivots
Ntabwo buri nkuru igenda neza, kandi izo nizo wigira kuri benshi. Twigeze gusubiramo umushinga wuburyo bugoye bwa micro-latch muri 17-4PH idafite umwanda. Igice cyari gifite urukuta ruto kandi ruto ruto rworoshye. Twari twizeye. Twabonye prototype yemewe, ariko mubikorwa byindege, agace ka hinge kagaragaje ubugome burigihe. Intandaro? Kurikirana ogisijeni ya ogisijeni mugihe cyo gucumura, yashizemo geometrie yihariye. Ikirere gisanzwe cyo gucumura nticyari cyera bihagije kuri iki kintu cyihariye kuri urwo rwego.
Gukosora byari bihenze: kwimukira mu itanura rya vacuum hamwe nigitutu cyigice cya hydrogène isukuye cyane kuri iyo ntambwe yihariye. Yishe intera yumushinga, ariko yakijije igice. Noneho, kubishushanyo byose bifite ultra-thin, ibintu bitwara imitwaro, dukora isesengura rikomeye cyane ryikirere cyacumuye hamwe nubufatanye bwacyo na chimie yihariye. Nibigenzurwa byongewe kurutonde rwa DFM (Igishushanyo mbonera cyo gukora) kubera kunanirwa.
Ikindi cyatsinzwe rwose ni ugukoresha nabi. Umukiriya yashakaga micro MIM kubintu byoroshye, bito. Byari shingiro shingiro. Twabikoze, ariko muri post-mortem, byaragaragaye ko guhinduranya mikoro cyangwa no gusya neza byari kuba byiza cyane kuri iyo geometrie. Imbaraga za Micro MIM ziragoye, ntabwo ari ubunini gusa. Twize gusubiza inyuma byinshi, kuyobora abakiriya inzira nziza, kabone niyo byaba bivuze gutakaza amagambo. Yubaka igihe kirekire.
Kureba imbere: Imitekerereze yo Kwishyira hamwe
Ibi byose bigana he? Igihe kizaza, ngira ngo, kiri muburyo bwimbitse bwo kwishyira hamwe no gushushanya neza. Turimo kubona inyungu nyinshi zo guhuza micro MIM nubundi buryo bwo gukora mikoro cyangwa guterana. Ariko urufatiro rukomeza kuba ibikoresho no gutunganya neza. Nukugira ishusho yuzuye, kuva ifu kugeza irangiye, igice giteranijwe.
Niyo mpanvu icyitegererezo cyumushinga uhagaritse guhuza uruganda birakomeye. Isosiyete yumva gushora imari na Igikonoshwa kubice binini, bigoye bizana ibisobanuro byuzuye kubyuma bitemba no gukomera kumeza. Iyo nabo bakora muri micro MIM kandi neza Imashini ya CNC, nkibikorwa byagaragajwe na QSY, barashobora guhitamo gukora inzira nziza kubintu runaka. Iki gice kibereye neza gushora imari mito cyangwa MIM ya micro? Kugira ubushobozi bwombi munsi yinzu imwe bisobanura igisubizo giterwa nubuhanga bwa tekiniki, ntabwo biterwa nuburyo bumwe iryo duka ritanga.
Kubantu bose bishira mumashanyarazi aciriritse, inama ntagusabye ni iyi: reba hejuru yimashini. Reba urusobe rw'ibinyabuzima byose - inkunga ya siyanse y'ibikoresho, ubushobozi bwa kabiri bwo gutunganya, kandi cyane cyane, amateka yo gukemura ibibazo by'ikipe mukorana. Tekinoroji iratangaje, ariko nubunararibonye bwakusanyirijwe hamwe, bigoye gutsindirwa hafi yayo bihindura micro-igice gikonje mubice byizewe, byakozwe cyane. Nibyo gusya inyuma yicyubahiro.
