Iyo wunvise 'ibicuruzwa byatewe inshinge', ishusho ihita iba ntoya, igoye, nini cyane-ibikoresho, ibikoresho byo kubaga, ibikoresho byimbunda. Nibyo, ariko kandi niho inganda zisanzwe zitangirira. Abantu batekereza ko MIM aribindi bihendutse muburyo bwo gutunganya imiterere itoroshye. Mubyukuri, intsinzi ishingiye ku gishushanyo mbonera cyo gukora uhereye ku gishushanyo cya mbere cyane, ikintu wiga gusa nyuma yo kubona amatsinda make ahenze ahinduka ibisakuzo. Ntabwo ari inzira y'ubumaji; ni urunigi rufite gahunda yo kugaburira ibiryo, kubumba, gutesha agaciro, no gucumura, aho buri murongo ugomba guhindurwa neza kubintu. Fata ikirere cyangiritse nabi kubice byicyuma, kandi urareba ipikipiki ya karubone kandi ikananirwa kwangirika. Nabonye bibaho.
Intego ya MIM: Nibikorwa, ntabwo ari ibicuruzwa gusa
Reka dusenye ukuri. Ibikurura ni net-shusho cyangwa hafi-net-umusaruro. Urashobora kubona impapuro zidashoboka hamwe no gushora imari cyangwa kubuza guhenze hamwe no gutunganya CNC. Ariko 'hafi-net-shusho' nijambo rikoreshwa. Hariho kugabanuka-guhanurwa ariko ntabwo buri gihe ari kimwe. Niba igishushanyo cyawe gifite ibice binini kandi binini urukuta-kurukuta, urasaba kugoreka mugihe cyo gucumura. Twigeze gukora kuri prototype yuburyo bwo gufunga, igice gifite icyuma cyoroshye cyinjijwe murwego ruremereye. Kwiruka kwambere byasohotse mu itanura ryoroheje gato, bihagije kugirango latike ihambire. Gukosora ntabwo byari mubipimo bya MIM byonyine; byari ubufatanye bufatika bwo kongeramo akantu gato, gashyigikirwa by'agateganyo muri leta yicyatsi nyuma yaje gukurwaho mumashini ya kabiri. Iyo ni isi nyayo.
Guhitamo ibikoresho ni ikindi gikoko. Ibisanzwe nka 17-4PH ibyuma bitagira umuyonga cyangwa ibyuma-bito byoroheje ni inzira zikandagira. Ariko iyo umukiriya aje gusaba a kubumba ibyuma igice muri nikel-ishingiye kuri superalloy ya progaramu yo mu kirere cyohejuru, umukino wose urahinduka. Ifu igura ikirere, ibisabwa mu itanura risabwa bikabije (vacuum nyinshi, ubushyuhe bwuzuye), kandi marike yamakosa irashira. Ibikoresho bya mehaniki nibyiza niba ubishyizeho imisumari, ariko ikiguzi cyiterambere ni kinini. Ibi ntabwo ari amagambo-yawe-mu-saha.
Aha niho kugira umufatanyabikorwa ufite ibibazo byimbitse byibanze. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) azana imyumvire itandukanye. Hamwe nimyaka irenga 30 mugushushanya ibishishwa, gushora imari, no gutunganya CNC, basobanukiwe imyitwarire yicyuma - impinduka zicyiciro, imiterere yintete, imihangayiko - uhereye kumpande nyinshi. Iyo firime nkiyi yongeyeho ubushobozi bwa MIM, ntabwo bagura imashini gusa; barimo gukoresha imyaka mirongo yubumenyi bwibintu. Kugenzura inshingano zabo kuri tsingtaocnc.com, urabona akazi kabo hamwe na cobalt na nikel alloys mugushora imari. Ubwo buhanga busobanura mu buryo butaziguye gucunga ibyo bikoresho byoroshye mu itanura rya MIM, uteganya uburyo bizagenda byiyongera nibintu bya nyuma ugomba gutegereza. Nibyiza cyane kurenza iduka rikora MIM gusa.
Aho MIM ikwiranye (Kandi aho idakwiriye)
None, ni ubuhe buryohe-bwiza ibicuruzwa byo gutera inshinge? Ubuvuzi ni bunini. Biopsy ihatira urwasaya, imitwe ya orthodontique, ibice byo kubaga ibintu. Umubumbe ushimangira ibikoresho, ibintu bigoye ni byinshi, kandi ibikoresho (akenshi 316L bidafite ingese) nibintu bya MIM. Ubuso burangiza buturutse kumucumuro nibyiza bihagije kubikorwa byinshi biocompatable, rimwe na rimwe bikenera gusa gucika intege cyangwa passivation.
Ariko hano hari aho bitari bikwiye. Umukiriya yashakaga umurongo munini, wubatswe - hafi yubunini bwikiganza. Geometrie yari nziza, ariko ikintu gikomeye cyari ingaruka zikomeye mubyerekezo runaka. Mugihe MIM ishobora kugera ku mbaraga nziza zingutu, imiterere ya isotropique y igice cyacumuye (imitungo isa nicyerekezo cyose) ntishobora guhuza imigendekere yintete ikura mubihimbano kubyo bikenewe cyane. Tugomba gusaba kurwanya MIM no kubereka inzira yo guhimba. Kumenya igihe udakoresheje ikoranabuhanga ningirakamaro nko kumenya igihe cyo kuyikoresha.
Imashini zikoresha amamodoka ni akandi gace gakura. Inzu ya Sensor, ibikoresho bito kubakoresha, ibice byo gutera lisansi. Guhindura ibinyabiziga byamashanyarazi birahindura igice kivanze, ariko icyifuzo cyibikoresho bito, byuzuye neza muri pompe, sensor, hamwe na connexion biracyahari. Umuvuduko hano uri kubiciro no guhuzagurika miriyoni yibice. Igipimo gifite inenge cyemewe kubice byo mu kirere gito ni ibiza hano. Aha niho kugenzura ibikorwa no gukurikirana imikorere yimibare kumurongo wa MIM biba bidashoboka.
Handoff: Ibikorwa bya kabiri hamwe nukuri-Kwishyira hamwe kwisi
Hafi nta gice cya MIM cyarangiye rwose nyuma yo gucumura. Benshi bakeneye ibikorwa bya kabiri. Iki nicyiciro gikomeye benshi birengagiza mugiciro cyambere. Urashobora gukenera imashini ya CNC kugirango ikubite kwihanganira ± 0.01mm kumurongo wihariye, cyangwa gukora ikintu kidashobora kubumbabumbwa, nkimbere yimbere yimbere. Urashobora gukenera gusya, kuvura ubushyuhe, cyangwa isahani.
Izi ninyungu zihishe zumushinga uhagaritse. Ongera ufate urugero rwa QSY. Niba igice cya MIM cyacumuye gisohotse kandi gikeneye CNC isya neza cyangwa umwobo wafashwe, barashobora kuyimurira mubice byabo. Nta gutinda koherezwa, nta tandukaniro ryitumanaho riri hagati ya injeniyeri MIM na mashini kubyerekeye umwihariko wigice (nkubuso bwacyo bworoshye ugereranije nicyuma gikozwe). Gutanga ibitekerezo birakomeye. Bashobora kuvuga, Iki gice cya MIM kitagira umwanda cyakomye gato nyuma yo gucumura, bityo tuzahindura umuvuduko wibikoresho hanyuma tugaburire kuri CNC. Uku kwishyira hamwe kuzigama umwanya, ikiguzi, no kubabara umutwe.
Ikindi kibazo nyacyo ni ubugenzuzi bufite ireme. Nigute ushobora kugenzura ubwinshi bwimbere bwikigo, gito cya MIM? Igerageza ryangiza ni igipimo cya zahabu-gabanya, kogesha, reba microstructure munsi ya microscope. Kubyara umusaruro, wishingikiriza kugenzura inzira: ukurikirana neza ubushyuhe bwumucyo, igihe, nikirere kuri buri cyiciro. Ariko kugira ubushobozi bwo gukora isesengura ryibyuma murugo, isosiyete imaze igihe kinini ikora no gutunganya imashini yaba ifite, numutungo munini wo kwemeza ingingo zambere no gukemura ibibazo.
Kuringaniza Ibiciro: Igikoresho, Umubare, nibintu bitagaragara
Amategeko ya kera ni uko MIM ihinduka ubukungu hafi ibice 10,000+ ku mwaka, kubera igiciro cyibikoresho. Ngiyo intangiriro nziza, ariko biroroshye cyane. Ikigereranyo nyacyo kirimo igice kigoye. Niba igice gisaba CNC 5 zitandukanye hamwe n imyanda 80%, MIM irashobora kubahendutse kubice 5.000. Igikoresho cya MIM ni nkibishushanyo mbonera bya pulasitike - bigoye, ibyuma bikomeye. Nibiciro byuzuye.
Ariko ibiciro bitagaragara biri mumajyambere no mubushobozi. Uzanyura mubikorwa byinshi: igikoresho cya prototype yo kwemeza igishushanyo, igikoresho cyambere cyo gukora, hanyuma akenshi ugahuza neza igikoresho nyuma yikigeragezo cya mbere cyo gucumura kugirango ubaze kugabanuka. Buri cyiciro gifata igihe n'amafaranga. Kubintu byingenzi, ugomba rero kuzuza inzira zose - ntabwo ari igice cyanyuma. Umukiriya wawe (cyane cyane mubuvuzi cyangwa mumodoka) arashaka kugenzura uwaguhaye ibiryo, ibiti byawe byo gucana, gahunda yo kugenzura ubuziranenge. Iki nigikorwa cyamezi.
Aho ibigo bifite ishingiro ryinganda nini nka QSY bishobora kugabanya ibi binyuze mubumenyi buringaniye. Ubunararibonye bwabo muguhitamo uburyo bwo gushora imari kuri nikel ishingiye kuri nikel ishingiye kuri turbo turbine ikubiyemo ibintu bisa - kugenzura gushonga, kubumba, no gukomera. Iyo disipuline ikurikirana isobanura neza umurongo wa MIM. Basobanukiwe impapuro, ibisobanuro, hamwe no kwemeza inzira ikenewe kugirango bakore inganda zagenzuwe, niho usanga imirimo myinshi ya MIM ifite marge nziza.
Kureba imbere: Ntabwo ari Gusimbuza, Ihitamo rikomeye
MIM ntabwo igiye gusimbuza ishoramari kubice binini, binini bikikijwe n'inkuta nka turbine. Ntabwo izasimbuza imashini ya CNC kuri prototypes imwe cyangwa ibice hamwe no kwihanganira gukabije kuri buri kintu. Kandi rwose ntizisimbuza kashe kubintu byoroshye, byogeje.
Ibyo ikora bifata umwanya wingenzi kandi ukura: ibice byinshi-bigoye, bito-bito-biciriritse-byuma byuma byinshi. Igihe kizaza kiri mukuvanga-ukoresheje MIM kugirango ukore 95% yimiterere yibice, hanyuma ukoreshe imashini itomoye cyangwa na micro-mashini kugirango urangize ibintu bikomeye. Ni mugutezimbere ibiryo bishya kubikoresho nka titanium, kugeza ubu bizwi cyane muri MIM kubera reaction yayo.
Kurangiza, gutsinda ibicuruzwa byo gutera inshinge biva mubukwe bwo gushushanya intego n'ubushobozi bwo gutunganya. Irasaba uwashushanyije gutekereza kubijyanye nifu ya powder, kuvanaho binder, no kugabanuka kugabanuka. Kandi birasaba uwabikoze kugira ibirenze MIM gusa; bakeneye ubumenyi bwimbitse bwa metallurgjiya, kugenzura inzira zikomeye, kandi kenshi, ubushobozi bwo gukora ibikorwa bya kabiri bikenewe. Ngiyo itandukaniro hagati yumucuruzi nabafatanyabikorwa. Iyo usuzumye uwaguhaye isoko, reba ibirenze MIM yabo. Reba ibikoresho byabo byose hamwe nibidukikije bikora - nkimyaka mirongo yo gutara no gutunganya inyuma yikigo nka QSY - kuko ubwo bumenyi shingiro nicyo cyemeza ko igice cyawe kitava mubibumbano gusa, ahubwo kigakora neza muburyo bwiza.
