Iyo wunvise 'gushora imari byihuse', benshi batekereza ko ari ugukubita inshyi 'byihuse' inzira ishaje yatakaye. Ngiyo umutego wambere. Kwihuta kwukuri hano ntabwo ari ukuzenguruka igihe gusa; ni uburyo bushya bwo gutekereza ku musaruro w'icyitegererezo, kurasa, no gutesha agaciro, byose mugihe ukomeje ubudahemuka buke butuma ishoramari rifite agaciro. Amaduka menshi arabisaba, ariko itandukaniro riri hagati yo gusaba no gutanga niho umurimo nyawo - hamwe no gutsindwa gushimishije - bibera.
Ibitekerezo Byibanze: Umuvuduko nubunyangamugayo
Ikosa rikomeye mbona nukwibwira ko ushobora kwihutisha inzira gakondo. Ntushobora. Gusuka amafaranga mumashanyarazi yihuta ya 3D kubishushanyo ni ikintu kimwe, ariko niba gahunda yawe yo kubaka igikonoshwa idashobora gukomeza, cyangwa ukwezi kwawe gutwikwa guhinduka, umaze gukora icyuho gihenze cyane. Igice 'cyihuta' kigomba guhindurwa mubyiciro byose, kandi ubwo buhanga ntibushobora kuganirwaho. Nuburinganire, burigihe buringaniza, hagati yubushyuhe bwamashanyarazi yuburyo bushya bwimbaraga nimbaraga zikenewe mugukemura.
Kurugero, twigeze kugerageza kwemeza ibikoresho bishya bya UV-byakize byasezeranijwe kugabanya 60% mugihe cyo gukora. Umuvuduko wari ukuri. Ikibazo cyagaragaye mugihe cya autoclave dewaxing. Coefficient itandukanye yo kwagura ubushyuhe ugereranije nigishashara gisanzwe cyateje micro-crack mu ikoti ryambere rya slurry, biganisha ku gipimo cya 40% cyo gutsindwa mugace ka mbere. Nubwoko bwihuta 'bugutwara igihe kinini namafaranga. Byadusunikiraga gusubira muri laboratoire kugirango duhindure imitekerereze ya slurry hamwe na binder igereranya kubwibyo bikoresho bishya. Igisubizo nticyari rusange; cyari gikosowe.
Aha niho uburambe bwigihe kirekire bwibikorwa buba ingirakamaro. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe na fondasiyo yimyaka 30 muri Igikonoshwa na gushora imari, birashoboka ko yabonye inzinguzingo zo guhanga no gusubira inyuma. Urwo rwibutso rwinzego zuburyo ibikoresho bitwara mukibazo nicyo kibuza guhubuka buhumyi mubisubizo bishya 'byihuse'. Urashobora kubona byinshi kubijyanye nuburyo bwabo kurubuga rwabo, tsingtaocnc.com. Umwihariko wabo hejuru yicyuma kugeza kuri nikel ishingiye kuri nikel yerekana ko basobanukiwe ko ibipimo byihuta byibyuma bitagira umwanda bitazakoreshwa kuri cobalt. Nibyo.
Impinduramatwara y'Icyitegererezo: Kurenga Icapiro rya 3D
Nibyo, icapiro rya 3D, cyane cyane stereolithography (SLA) cyangwa guhuza indege, ni irembo rya benshi muri prototyping yihuse yo gukina. Ariko gufata igishushanyo cyacapwe nkigisimbu cyibishashara kiziguye nikosa rokie. Ubuso burangije, ivu ririmo nyuma yo gutwikwa, hamwe na polymers zisigaye zose zikorana nigikonoshwa ceramic zitandukanye. Ukenera kenshi igifuniko cya kabiri cyangwa cyahinduwe cya mbere cyoroshye kugirango ushire hejuru.

Ndibuka umushinga wibikoresho bya turbine muri ibyuma aho umukiriya yari akeneye prototypes 30 ikora kugirango igerageze moteri. Ibishushanyo mbonera bya 3D byacapishijwe byari kuba bihenze cyane. Twacapye shobuja, dushiraho uburyo bwihuse bwa urethane, hanyuma dushiramo inshusho yo hasi-gushonga. Yongeyeho icyumweru kumbere-iherezo ariko ikiza hafi ibyumweru bitatu mugice cyo gushushanya icapiro kandi iduha byinshi biranga ibishushanyo mbonera. Igikonoshwa cyarafashwe, gutora byari byumvikana, kandi umukiriya yabonye ibizamini byabo kuri gahunda. Nibyo bifatika byihuse gushora imari.
Kubaka Igikonoshwa: Gukora-cyangwa-Kumena Icyiciro
Aha niho inzira igirira ikizere cyangwa igatandukana. Kuma byihuse ni ibishuko - ukoresheje umwuka uhatirwa, umwanda, cyangwa ubushyuhe bworoheje. Ariko byihute, hanyuma ugatega ubuhehere cyangwa ugakora laminations nke hagati yamakoti. Igikonoshwa gishobora kugaragara neza kugeza gikubise itanura, noneho bikananirana bikabije. Twimukiye mubyumba bidukikije bigenzurwa nubushuhe bwuzuye no gukurikirana ubushyuhe. Byumvikane nkibanze, ariko ubu bugenzuzi buradufasha guhanura kugabanya igihe cyo gukama hagati yikoti 20-30% tutabangamiye ubunyangamugayo. Ntabwo ari flash, ariko ni ngirakamaro.
Guhitamo stucco-umucanga wangiritse ushyirwa hagati yibitonyanga-ni ikindi kintu cyiza. Coarser, stucco nyinshi irashobora kubaka uburebure bwikigero cyihuse, kugabanya umubare wamakoti asabwa kubwubugari bwatanzwe. Ariko irashobora kandi gukora imbere yimbere imbere kuri casting. Kubice bisaba ubuso bwiza burangiye, urashobora gukomera hamwe na stucco nziza kandi ukemera amakoti menshi. Nta sasita y'ubuntu; buri gihe-cyo gufata icyemezo gifite ubucuruzi-ku kindi kiranga.
Kuri binini bivanze, nka nikel QSY ikorana na, shell chemistry ubwayo nibyingenzi. Igikonoshwa kigomba kwihanganira ubushyuhe bwo hejuru butarinze gukoreshwa nicyuma gishongeshejwe. Inzira 'yihuta' ikoresha ibishishwa bisanzwe byuma bya karubone bizananirana rwose na superalloy. Igikonoshwa gishobora koroshya cyangwa gukora inclusitions. Noneho, uburyo bwihuse 'bugomba kuba bwihariye. Akazi kabo k'igihe kirekire mu mavuta adasanzwe, nkuko bigaragara mu mwirondoro wabo, bivuze ko bagomba guteza imbere (kandi birashoboka ko barinda) sisitemu y'ibicuruzwa byihariye kuri ibyo bikoresho.
Dewaxing na Burnout: Thermal Gauntlet
Iyi niyo ntambwe itangaje. Imashini gakondo ikora autoclaving ikora ariko irashobora gutinda kubishusho binini. Flash dewaxing mumatanura yubushyuhe bwo hejuru irihuta ariko itera ihungabana ryinshi ryumuriro kuri shell. Twagize ibishishwa biturika rwose mugihe ibishashara byagutse byihuse. Ubwumvikane twakemuye nuburyo bubiri: inzira ngufi, yumuvuduko ukabije wa autoclave cycle kugirango ikureho igice kinini cyibishashara, ikurikirwa no gutwika itanura ryagenzuwe kugirango ikureho ibisigazwa no gucumura igikonoshwa. Ntabwo aribwo buryo bwihuse, ariko butanga igipimo kinini cyo kubaho kuri geometrike igoye.
Inzira yo gucana ni akandi gace keze neza. Intego ni ugukuraho ibisigisigi byose byashushanyije nta guhangayikishwa cyane na ceramic. Thermocouples yashyizwe imbere muri dummy shell ifasha gushushanya ikarita yumuriro. Mugusesengura aya makuru, twashoboye gukora ibice byihuta byihuta mubice byubushyuhe aho igikonoshwa gihamye cyane, kandi kigenda gahoro binyuze mubyiciro byinzibacyuho. Yogoshe hafi 25% mugihe cyitanura ryacu. Nuburyo bwimikorere yamakuru ya 'yihuta', ntabwo ari ugukeka.
Kunanirwa hano bihenze. Igikonoshwa cyacitse cyavumbuwe nyuma yo gucanwa bivuze ko watakaje igihe cyose nigiciro cyashowe kugeza icyo gihe - icyitegererezo, ubunebwe, umurimo, imbaraga. Niyo mpamvu imitekerereze 'yihuta' igomba kuba ikubiyemo kwemeza inzira ikomeye. Wihutisha intambwe ushobora kugenzura no gupima, hanyuma ugasiga buffers aho ibyago ari byinshi.
Gukora Imashini: Kurangiza Byingenzi
Ishoramari ryihuse ntirikorwa mugihe igice kinyeganyezwa hanze. Leta-ya-reta hafi ya yose isaba bamwe Imashini ya CNC—Gucukura, gusya mumaso akomeye, umugozi. Aha niho urunigi 'rwihuta' rushobora kongera gucika niba casting itagenewe gukorwa (DFM) kuva yatangira. Niba uzigama ibyumweru bibiri kuri casting ariko hanyuma ukenera ibyumweru bitatu bigoye, gutunganya byinshi-axis kubera imibare mibi ya datum cyangwa ibintu bitagerwaho, watsinzwe isiganwa.
Ubufatanye bwa hafi hagati yimishinga nububiko bwimashini ni ngombwa. Mubikorwa byahujwe nka QSY, aho casting na Imashini ya CNC bari munsi yinzu, iyi handoff igomba kuba idafite ikidodo. Barashobora gushushanya uburyo bwo gukina bakoresheje ibikoresho byo gutunganya, bakongeramo ububiko buke ahantu heza, kandi bakemeza ko imashini ishobora gukoreshwa. Kurugero, urwego runaka rwa ibyuma Irashobora guta neza ariko kuba inzozi kumashini niba kuvura ubushyuhe bidacunzwe neza nyuma yo guterwa. Utanga integuro ikemura ibyo bikomeza.
Imishinga yihuse cyane Nagize uruhare buri gihe ninjizamo abakanishi mugusubiramo ibishushanyo mbonera. Bashobora kwerekana umushinga muto uhindura inguni yemerera ibintu byoroshye, cyangwa bagasaba kwimura umurongo wo gutandukana kugirango bakore datum isukuye. Ibyo biganiro, bibera imbere, nibyo bituma umuyoboro wose - kuva muburyo bwa digitale kugeza urangije, imashini ikozwe - mubyukuri byihuse kandi byizewe.
Umwanzuro: Ni Filozofiya, Ntabwo Akabuto
Noneho, nyuma yibi byose, niki gushora imari byihuse? Ntabwo ari ikoranabuhanga na rimwe ugura. Ni filozofiya yuburyo bunoze bwo gutezimbere, bushigikiwe nibikoresho byimbitse ubumenyi nubushake bwo gukora ubushakashatsi bugenzurwa (kandi wemere kunanirwa). Nukumenya aho ushobora gusunika n'aho ugomba kwihangana. Ni itandukaniro riri hagati yububiko bukora casting nimwe itanga ibisubizo byubushakashatsi mugihe cyumuvuduko.
Ibigo bikora neza, bifite imyaka mirongo yandika kubikoresho bitandukanye nka icyuma n'amavuta adasanzwe, yabonye umuvuduko wabo. Barayubatse binyuze mu kwegeranya, rimwe na rimwe birababaza, uburambe. Bamenye ko kwihuta kwukuri ari ukugabanya igihe cyose cyo kuyobora mugihe gikora, cyujuje ibisabwa, ntabwo ari amasaha gusa icyuma kimara mubibumbano. Iyo niyo ntego nyayo, kandi biragoye cyane-kandi birashimishije-kuruta uko byumvikana.
