Iyo utangiye kureba uruganda rutera ibyuma, ubushakashatsi bwambere burigihe ninyanja yibisabwa-bisa: ibisobanuro bihanitse, geometrike igoye, bikoresha amafaranga menshi. Irazimya impungenge zanjye igihe cyose. Itandukaniro nyaryo ntabwo riri muri kopi yo kwamamaza; yashyinguwe mubikorwa byububiko, gukurikiranira hafi ibintu, nuburyo isosiyete ikemura ikibazo cyo kwangirika ku gicamunsi. Abaguzi benshi bakosorwa kubikorwa bya MIM ubwabyo, bakibagirwa ko ari umuhuza umwe gusa mumurongo utangirira kumatungo ukarangira urangije, akenshi wakozwe, igice. Aho niho gutandukana bibera.
Icyuho cyibanze: Aho MIM ikunze gutsitara
Dore ukuri gufatika Nize inzira igoye: a uruganda rutera ibyuma ikorera mu cyuho ni akaga. Inzira isanzwe ikora hafi-net-shusho ibice, ariko hafi-net ni spekiteri. Hafi buri gihe, urareba ibikorwa bya kabiri. Nabonye imishinga isenyuka kubera ko inzu ya MIM yagombaga kohereza ibice hanze kubikorwa bikomeye bya CNC, gutakaza ubushobozi bwigihe, ubwiza, ndetse n’itumanaho ryibanze. Kugoreka icyaha byari mu buryo bwihariye, ariko amasura yo gushakisha nyuma yo gukora ntabwo yari, kandi icyiciro cyose cyarakuweho nyuma yo gukora. Kunanirwa ntabwo byari muri MIM; byari mu ntoki.
Niyo mpamvu amateka shingiro yisosiyete afite akamaro kuruta agatabo kayo MIM. Fata ushikamye nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Urubuga rwabo ntiruyobora hamwe na tekinoroji ya MIM. Ahubwo, iragushingira mumyaka 30 yo gukina no gutunganya. Ibyo birambwira ikintu gikomeye: basobanukiwe nicyuma. Bakemuye imiterere yingano yibyuma bitagira umwanda, guhangayikishwa na nikel ishingiye kuri nikel, hamwe ninzozi mbi ziterwa na geometrike mbere yo gusuzuma MIM. Kuri bo, kongeraho MIM ntabwo ari pivot; ni inzira yuzuzanya mubiganiro birebire cyane byo gukora. Iyi background ni buffer irwanya MIM isanzwe yo gufata igice cyicyatsi nkibicuruzwa byanyuma.
Ubuhanga bwibikoresho nibindi byiza byo guceceka. Iyo a uruganda rutera ibyuma urutonde rwibintu bidasanzwe nkubushobozi, ugomba gucukura. Bishatse kuvuga ko bashizemo uduce duke, cyangwa bafite metallurgiste bumva uburyo ibinyomoro bishingiye kuri cobalt bitwara binyuze mumashanyarazi yubushyuhe? Isosiyete yashinze imizi mu gushora imari no gutunganya ibyo bikoresho imaze kugira ubwo bumenyi bw'inzego. Kwiga kwabo kuri MIM hamwe na Inconel bijyanye no kubumba no gutesha agaciro, ntabwo ari metallurgie yibanze. Ibyo bigabanya umushinga wawe ibyago bya tekiniki.
Kwishyira hamwe kwingirakamaro: CNC nkibidashoboka
Reka tumenye neza ibya ops ya kabiri. Ibikoresho byo kubaga, urugero. Inzira ya MIM irashobora gukora umubiri utoroshye, ariko umwobo wa pivot ukenera kurangiza Ra 0.4 hamwe no kwihanganira ± 0.025mm gucumura byonyine bitazagerwaho. Niba utanga MIM afite munzu CNC, nkuko QSY ibishimangira, igice ntigisiga sisitemu nziza. Umukanishi arashobora gukorana na injeniyeri ya MIM kugirango ashushanye ibikoresho byo gucumura bitanga imibare myiza yimashini. Bavuga ururimi rumwe. Ndibuka urubanza rufite moteri ya moteri ya mazutu inzu yubatswe imbere yananiwe. Amaduka yo hanze ya MACHINE yashinje ububi bwa MIM. Amaduka ya MIM yashinje tekinike mbi yo gutunganya. Hamwe nogutanga ibintu byose, umukino wamakosa ugwa mumatsinda umwe wubwubatsi ukemura ikibazo, byaje guhinduka gato muburyo bwo kugaburira amatungo kugirango tunoze imashini.
Uku kwishyira hamwe kandi guhindura igishushanyo mbonera (DFM) ibiganiro. Ntabwo bikiri intoki zikurikirana. Ni ikiganiro kimwe. Urashobora gushushanya ibiranga uzi ko bizabumbabumbwa, bigacumura, hanyuma bigakorerwa mubigenzurwa, bikungahaye cyane kubitekerezo. Igiciro cyibintu byoroshye cyane birashobora gusubirwamo muguhuza gahunda ya CNC nyuma. Benshi uruganda rutera ibyuma ntishobora gutanga icyo gitekerezo cyuzuye; optimizasiyo yabo ihagarara kuri leta yacumuye.
Byongeye kandi, tekereza kuri prototyping hamwe nibikoresho byikiraro. Rimwe na rimwe, ukenera ibizamini bikora mbere yo kwiyemeza igikoresho cyuzuye cya MIM. Inzu ikomatanyirijwe hamwe irashobora gukora imashini prototipes ziva mububiko bwibigenewe, biguha ibintu-bisa nkibikoresho byo kwipimisha. Nuburyo bufatika, bwo kuzigama ibiciro udukino dukinisha MIM idashobora kwigana byoroshye.
Ibikoresho bifatika: Kurenga urupapuro rwamakuru
Umuntu wese afite urupapuro rwamakuru kuri 17-4PH ibyuma bidafite ingese. Ubumenyi nyabwo buri mubitekerezo. Nigute imyuka isigaye ya karubone ivuye muri sisitemu ya binder ikorana nimvura igabanya ubukana? Isosiyete ifite amateka yimbitse yamaze guhangana na variable yo kuvura ubushyuhe mumyaka mirongo. Ntabwo bakurikiza gusa icyiciro rusange cyo gucumura MIM; barimo kuyihindura ukurikije ubunini bwigice cyigice hamwe nibintu byifuzwa byanyuma, nkuko babikora hamwe nigipimo cyo gukonjesha.
Ibi nibyingenzi kubice biterwa numunaniro cyangwa ruswa. Nabonye ibice byo mu nyanja bikozwe muri 316L binanirwa imburagihe kubera ko inzira ya MIM, mugihe igera ku bucucike, ibumoso busobekeranye bwabaye urubuga rwo gutangiza ruswa. Utanga ikirenge muburyo bwo gukora (casting / MIM) hamwe no gukuramo (gutunganya) isi birashoboka cyane gufata ibi. Bashobora kwerekana ubushyuhe burenze gato bwo gucumura cyangwa igihe kirekire cyo gufata, bagacuruza gato kugenzura ibipimo byemewe, kuko babonye uburyo bwo gutsindwa mumurima.
Gukorana nudusimba twihariye nka nikel cyangwa cobalt ishingiye kubindi bikenewe. Ntabwo zihenze gusa; biragoye gukora imashini. Umuterankunga uhuriweho azi neza ibicumuro bitanga impanuro nziza hagati yimikorere ya mashini yanyuma na machinability. Bashobora no gusaba inama yihariye nyuma yo gucumura mbere yuko CNC ikora kugirango yoroshe kwambara ibikoresho, igitekerezo kibaho cyane ku masangano yubushobozi bwabo bubiri.
Ingano na Viability: Ikigereranyo Cyukuri
Amategeko ya kera ni uko MIM iba ubukungu kuri, tuvuge, ibice 10,000+ kumwaka. Ariko iyo niyo mibare idafite aho ihuriye. Ikigereranyo nyacyo kirimo ibikoresho, ibikoresho bigoye, igiciro cya kabiri cyibikorwa, nibikoresho. Igice kitoroshye gisaba imashini 5-axis nyuma yo kubumba irashobora kubona ingingo yayo yamenetse igabanuka kugeza kubice 5.000 niba MIM ishobora gukuraho imashini eshatu. Isosiyete ikomatanyije irashobora gukora isesengura ryibiciro byose neza kuko igenzura impinduka zose.
Nakoze umushinga wo gushakisha imbunda - agace gato, gahangayitse cyane. Uburyo gakondo bwari CNC kuva mukabari gakomeye, hamwe n’imyanda irenga 60%. Ijambo rya MIM ryihariye ryasaga neza, ariko amagambo ya kabiri yatunganijwe kuva mugice cya gatatu yari menshi kandi ahindagurika. Twahinduye kubitanga nkicyitegererezo QSY ihagarariye. Amagambo yabo yari ayarangije, yiteguye-guteranya igice. Byari hejuru kumurongo wa MIM ariko 30% munsi muri rusange. Bari barahinduye imigendekere yose, ndetse bashushanya uburyo bwo gusiga ububiko buke kuri CNC ya nyuma. Umushinga wari mwiza kuko babonye ishusho yose.
Ibinyuranye, kubintu byoroheje, bifite amajwi make, MIM akenshi ihitamo nabi, kandi utanga isoko nziza azakubwira ibyo. Bashobora gutanga igitekerezo cyo gutangirira kumurongo wuzuye uhereye kumurongo wibishushanyo mbonera no kurangiza byihuse CNC, bikagukiza ishoramari ryimibare itandatu. Ubwo kuba inyangamugayo biranga umufatanyabikorwa, ntabwo ari umucuruzi gusa.
Igenzura rifatika: Ibibazo byo Kubaza Kurenga Ubushobozi Urupapuro
Nigute ushobora gusuzuma a uruganda rutera ibyuma iyo imbuga zabo zose zisa nkubushobozi? Ntubaze kubyerekeye kwihanganira; baza kubijyanye no kwihanganira ibintu byinshi murwego rwa kabiri. Ntugasabe gusa ibyemezo bifatika; saba raporo kubyerekeye gukwirakwiza ubucucike ku gice cyambukiranya igice, cyangwa amakuru ku buso burangije nyuma yo gucumura, mbere yo gusya. Baza ibijyanye nigikorwa cyabo cya mbere cyo kugenzura - ni cheque ya CMM gusa, cyangwa ikubiyemo ikizamini gikora hamwe nibice byo gushyingiranwa?
Baza kunanirwa kwabo mumyaka ibiri ishize nicyo bize. Igisubizo kiratubwira. Isosiyete ifite imizi yimbitse izaba ifite inkuru yerekeye imyitwarire yibintu cyangwa imikoranire yimikorere, ntabwo ari ikibazo cyo guhuza gusa. Suzuma urunigi rwabo rwo kugaburira amatungo. Baravanga munzu cyangwa bakishingikiriza kubitanga hanze? Icya nyuma ni ingingo ishobora guteza akaga.
Hanyuma, shakisha ibimenyetso byuko kwishyira hamwe mubyigisho byabo. Berekana igice cyarangiye gifite imashini zisobanutse kandi bakavuga urugendo kuva mububiko kugeza kubyoherejwe? Cyangwa barerekana gusa igice kibengerana, cyacumuye? Iyambere yerekana ibintu bifatika byerekana umusaruro. Aba nyuma barashobora kugurisha inzozi. Muri uru rwego, abafatanyabikorwa bizewe cyane ni aberekana MIM atari igisubizo cyubumaji, ahubwo nkigikoresho gikomeye mumahugurwa afite ibikoresho byiza, azi ibyuma.
