Ikoranabuhanga rya Powder Injection Molding Technology (MIM) nubuhanga bushya bwa powder metallurgie hafi ya net-form-molding tekinoroji yashizweho no kwinjiza tekinoroji ya kijyambere ya pulasitike mu bijyanye na powder metallurgie.
Intangiriro ya tekiniki
Ikoreshwa rya porojeri ya porojeri ikomatanya ikorana buhanga nka tekinoroji ya plastike, chimie polymer, tekinoroji ya powder metallurgie, hamwe nubumenyi bwibyuma. Ikoresha ibishushanyo kugirango itere inshinge zuzuye kandi ikora vuba-ubucucike bwinshi, busobanutse neza, butatu-buringaniye buringaniye binyuze mu gucumura. Ibice byubaka. Ubwa mbere, ifu ikomeye hamwe na bingo kama bifatanyirijwe hamwe, hanyuma nyuma yo guhunika, binjizwa mu cyuho kibumbwe hamwe n’imashini ibumba inshinge mu buryo bushyushye kandi bwa pulasitike (~ 150 ° C) kugira ngo bikomere, hanyuma parison ikorwa no kubora imiti cyangwa kubora. Guhuza ibicuruzwa bivanwaho, hanyuma ibicuruzwa byanyuma bibonerwa no gucumura no gukomera.
Ubu buryo bwa tekinoloji ntabwo bufite ibyiza byuburyo busanzwe bwifu ya metallurgie nkintambwe nkeya, kutagabanuka cyangwa kugabanuka, hamwe ninyungu zubukungu, ariko kandi bunesha ibitagenda neza kubicuruzwa byifu ya porojeri gakondo nkibikoresho bitaringaniye, imiterere yubukanishi buke, hamwe ningorabahizi mugukora inkuta zoroshye kandi zubatswe. Birakwiriye cyane cyane kubyara umusaruro muto, bigoye kandi byihariye-bisabwa ibyuma. Ifite ibiranga ibintu bisobanutse neza, imiterere imwe, imikorere myiza nigiciro gito cyumusaruro.
Inzira
Inzira igenda: binder → kuvanga → gushushanya inshinge → gutesha agaciro → gucumura → nyuma yo gutunganya.
Ifu y'amabuye y'agaciro
Ingano yubunini bwifu yicyuma ikoreshwa mubikorwa bya MIM muri rusange ni 0.5 ~ 20μm; mubyukuri, nibyiza ibice, nini nini yubuso bwihariye, byoroshye gukora no gucumura. Ifu gakondo ya metallurgie ikoresha ifu ya coarser irenze 40 mm.
Ibifatika
Igikorwa cyo gufatira kungufu ni uguhuza ibice byifu yifu kugirango imvange igire rheologiya hamwe namavuta iyo ashyutswe muri barri yimashini itera inshinge, nukuvuga ko ari umutwara utwara ifu itemba. Kubwibyo, binder yatoranijwe kugirango itware ifu yose. Kubwibyo, guhitamo gukurura ni urufunguzo rwo gushiramo ifu yose.
Ibisabwa kubifata kama:
1.Gukoresha ibifatika bike birashobora kubyara rheologiya nziza yuruvange;
2.Nta reaction, nta reaction ya chimique hamwe nifu yicyuma mugihe cyo gukuraho ibiti;
3.Byoroshye gukuraho, nta karubone iguma mubicuruzwa.
Kuvanga
Ifu yicyuma hamwe nububiko kama bivangwa kimwe kugirango bikore ibikoresho bibisi bitandukanye muruvange rwo kubumba inshinge. Uburinganire bwimvange bugira ingaruka muburyo butaziguye, bityo bikagira ingaruka kubipimo byo guterwa inshinge, kimwe n'ubucucike nibindi bintu byanyuma. Iyi ntambwe yo guterwa inshinge zirahuza muburyo bwo guterwa inshinge za plastike, kandi ibikoresho byayo nabyo ni bimwe. Mugihe cyo kubumba inshinge, ibikoresho bivanze bishyushya muri barri yimashini yatewe inshinge mubintu bya plastiki bifite imiterere ya rheologiya, hanyuma bigaterwa mubibumbano munsi yumuvuduko ukwiye wo gutera inshinge. Urushinge rwubatswe rugomba kuba rufite microscopique kugirango ibicuruzwa bigabanuke neza mugihe cyo gucumura.
Gukuramo
Igikoresho kama gikubiye mubibumbano bigomba gukurwaho mbere yo gucumura. Iyi nzira yitwa gukuramo. Igikorwa cyo gukuramo kigomba kwemeza ko ibifatika bisohoka buhoro buhoro biva mu bice bitandukanye byubusa ku miyoboro mito iri hagati yuduce tutagabanije imbaraga zubusa. Igipimo cyo gukuraho binder muri rusange gikurikiza ikigereranyo cyo gukwirakwiza. Gucumura birashobora kugabanuka no kugabanya ibice byangiritse byambaye ubusa mubicuruzwa bifite imiterere nimiterere. Nubwo imikorere yibicuruzwa bifitanye isano nibintu byinshi byakozwe mbere yo gucumura, mubihe byinshi, inzira yo gucumura igira ingaruka zikomeye cyangwa zikomeye kumiterere yimiterere yimiterere nimiterere yibicuruzwa byanyuma.
Nyuma yo gutunganywa
Kubice bifite ubunini busabwa neza, birakenewe nyuma yo gutunganywa. Ubu buryo ni bumwe nuburyo bwo gutunganya ubushyuhe bwibicuruzwa bisanzwe.
Ibyiza byo gutunganya
MIM ikoresha ibiranga tekinoroji ya powder metallurgie kugirango icumure ibice byubukanishi bifite ubucucike bwinshi, imiterere yubukanishi nubuziranenge bwubuso; icyarimwe, ikoresha ibiranga uburyo bwo guterwa inshinge za plastike kugirango itange ibice bifite imiterere igoye cyane kandi neza.
1.Ibice byubatswe bifite imiterere igoye cyane birashobora gushirwaho.
Gutunganya ibyuma gakondo bikubiyemo gutunganya ibyuma mubicuruzwa binyuze muguhindura, gusya, gutegura, gusya, gucukura, kurambirana, nibindi. Bitewe nigiciro cya tekiniki nibibazo byigihe, biragoye ko ibicuruzwa nkibi bifite imiterere igoye. MIM ikoresha imashini itera inshinge kugirango yinjize ibicuruzwa ubusa kugirango yizere neza ko ibikoresho byuzuza byuzuye umwobo, bityo bigatuma habaho kumenya imiterere igoye cyane.
2.Ibicuruzwa bifite microstructure imwe, ubwinshi bwinshi nibikorwa byiza.
Mubihe bisanzwe, ubucucike bwibicuruzwa byakanda bushobora kugera kuri 85% gusa yubucucike bwa theoretical; ubwinshi bwibicuruzwa byabonetse nikoranabuhanga rya MIM birashobora kugera kuri 96%.
3.Ubushobozi buhanitse, byoroshye kugera kubikorwa byinshi kandi binini.
Ifumbire y'icyuma ikoreshwa mu ikoranabuhanga rya MIM ifite igihe cyo kubaho gihwanye n'icy'ububiko bwa pulasitiki ya injeniyeri. Bitewe no gukoresha ibyuma, MIM ikwiranye no gukora byinshi mubice.
4.Ibikoresho byinshi byifashishwa hamwe nimirima yagutse.
MIM irashobora gukoresha ibikoresho hafi ya byose byuma, kandi urebye ubukungu, ibikoresho byingenzi bikoreshwa birimo ibyuma, bishingiye kuri nikel, amavuta make, ashingiye ku muringa, ibyuma byihuta cyane, ibyuma bitagira umwanda, garama valve ivanze, karbide ya sima, hamwe na metero ya titanium.
5.Bika cyane kubika ibikoresho bibisi
Mubisanzwe, igipimo cyo gukoresha ibyuma mugutunganya ibyuma no gukora ni bike. MIM irashobora kuzamura cyane igipimo cyimikoreshereze yibikoresho fatizo, nuburyo bwo gukoresha 100%.
6.Uburyo bwa MIM bukoresha ifu nziza ya micron.
Ntishobora kwihutisha kugabanuka kwicyaha gusa, ifasha kunoza imiterere yubukanishi bwibikoresho, kongera ubuzima bwumunaniro wibikoresho, ariko kandi binatezimbere kurwanya imbaraga zo kwangirika no kwangirika.
Ahantu ho gusaba
Ibicuruzwa byayo bikoreshwa cyane mubikorwa byinganda nkikoranabuhanga rya elegitoroniki, ibikoresho bya biomedical, ibikoresho byo mu biro, imodoka, imashini, ibyuma, ibikoresho bya siporo, inganda zireba, intwaro n’ikirere.
