Iyo abantu bumvise 'ibikoresho byubuvuzi', akenshi batekereza kubintu bidafite imbaraga, byaka cyane biturutse kumurongo. Ukuri kurakomeye. Byerekeranye na casting igomba kuba ifite ubunyangamugayo bwa vacuum mumyaka mirongo, cyangwa imashini ikora idashobora kunanirwa nyuma yizunguruka ibihumbi icumi muri autoclave. Ikinyuranyo hagati yo gushushanya nigice gikora niho imirimo nyayo ibera, kandi niho imyaka imara.
Urufatiro: Itangirana nabakinnyi
Ntushobora gukora imashini igice cyiza kuva casting mbi. Iri ni ryo somo rya mbere rikomeye. Kumashusho yibikoresho shingiro cyangwa imishwarara ivura gantry ibice, ubunyangamugayo bwibintu ntibishobora kuganirwaho. Twabonye imishinga ihagaze kuko intangiriro gushora imari yari ifite micro-porosity yagaragaye gusa mugihe cyo gutunganya bwa nyuma. Igiciro cyamazu yakuweho, hafi-yuzuye yuzuye ibyuma ni umwarimu wubugome.
Aha niho uburambe bwumushinga butegeka gutsinda. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu mugikonoshwa no gushora imari, yumva ko imbaraga zumuriro zo gusuka cobalt-chromium alloy kubikoresho byo kubaga bitandukanye rwose nicyuma gisanzwe kitagira umwanda. Ntabwo ari ugushonga ibyuma gusa; ni ukugenzura inzira yo gukomera kugirango wirinde ingingo zimpungenge ziba ingingo zananiranye.
Guhitamo hagati ya shell mold no gushora imari yatanzwe ibikoresho by'ubuvuzi igice akenshi bimanuka kuri geometrie no kurangiza ibisabwa. Ikintu kitoroshye, gifite uruzitiro ruto rwa pompe ya dialyse? Birashoboka gushora imari. Umunini munini, wubatswe kuburiri bwibitaro? Igikonoshwa gishobora kuba cyiza cyane utitanze kubikorwa. Icyemezo ntabwo buri gihe gisobanutse neza, kandi rimwe na rimwe gisaba prototyping inzira zombi.
Imashini itomoye: Aho kwihanganira kuruma inyuma
CNC gutunganya ibice byubuvuzi yumva bitandukanye. Hano hari uburemere bwimitekerereze. Kwihanganira ± 0.005mm kuri bore ntabwo ari igitekerezo; ni imipaka imipaka kuri kashe ihuza amazi yumubiri. Ndibuka icyiciro cyamazu yahuza kubakurikirana abarwayi aho twirukanaga 0.01mm yukuri guhamagarwa. Imashini yari ishoboye, ariko kwaguka no kwagura ubushyuhe bwo guca ibyuma 316L bidafite ingese byatujugunye. Twarangije tugomba kugenzura ubushyuhe bwibidukikije biduka cyane - birambuye ntabwo bishushanyije.
Uburyo bwa QSY Imashini ya CNC kubice byubuvuzi akenshi bikubiyemo kwitangira imirongo yimashini yihariye kubitsinda bimwe. Gukoresha nikel ishingiye kuri nikel, ikora-nkumusazi, kumurongo umwe hamwe nicyuma gikozwe muburyo bwibikoresho bidahuye nubuzima bwo kurangiza. Kubatandukanya bishobora gusa nkaho bidakorwa ku mpapuro, ariko birinda kwanduzanya kwanduza ibintu kandi bikomeza inzira ihamye. Ukwo gushikama nicyo kibemerera gukubita Ra 0.8μm hejuru yubuso burangiza buri gihe ku ngingo zikorera imitwaro, ningirakamaro mukurinda gutangira.
Iyemezwa rya nyuma yo gutunganya ni urundi rwego. Ntabwo ari raporo ya CMM gusa. Kubice byatewe cyangwa ibikoresho byigihe kirekire byitumanaho, dukunze kwerekana inzira yinyongera ya passivation cyangwa protocole yihariye yo gukora isuku kugirango dukureho microscopique ibice byose byashyizwe mubikorwa. Igice kirashobora kuba cyuzuye ariko muburyo bwa biologiya niba iyi ntambwe yihuta.
Alloy Dilemma: Ibikoresho ntabwo ari Umubare gusa
Kugaragaza ibyuma bidafite ingese ntacyo bivuze. Ni 304, 316L, cyangwa 17-4PH? Buriwese yitwara bitandukanye mugihe cyo gutara no gutunganya, kandi buriwese afite umwirondoro utandukanye wo kurwanya ruswa mubitaro byubuvuzi. 316L ni ifarashi ikoreramo kubwimpamvu nziza, ariko kubice bisaba imbaraga zisumba izindi, nkabashoferi ba magufa ya magufa cyangwa ibikoresho bimwe na bimwe bya arthroscopique, twishingikiriza kumanota akomera yimvura nka 17-4PH cyangwa muri idasanzwe.
Cobalt ishingiye kuri nikel ishingiye kuri nikel iri muri shampiyona yonyine. Zikoreshwa muburyo bukoreshwa cyane nko guhuza amavi ya prostate cyangwa mubushyuhe bwo hejuru bwa autoclave. Gutunganya kwabo biragoye cyane - umuvuduko muke wo kugabanya, ibikoresho byihariye bya geometrike, guhora gukonjesha kugirango ucunge ubushyuhe. Inyungu ni kwambara bidasanzwe no kurwanya ruswa. Igiciro ni ugukoresha amafaranga nigihe kirekire. Nabonye imishinga aho kuva mubintu bisanzwe bitagira umuyonga ukajya kuri cobalt ikubye kabiri igiciro cyo gukora, ariko niyo nzira yonyine yo kuzuza imyaka 15 yubuzima bwa serivisi.
Gukorana numufatanyabikorwa ufite ubumenyi bwimbitse bwo kumenya ibintu ni ngombwa. Ntabwo ari ukugira ibinyobwa gusa; ni ukumenya gushyushya-kubifata nyuma yimashini kugirango ugere kubukomezi bwifuzwa utabanje kugoreka, cyangwa uburyo bwo gukora sisitemu yo kwinjirira muri casting kugirango hamenyekane imiterere imwe yintete muburyo bugoye.
Uburyo bwo Kunanirwa n'impamvu
Umuntu wese avuga ibipimo ngenderwaho, ariko gusesengura ibyananiranye birigisha. Twagize ikibazo hamwe n'intoki ntoya ya robot yo kubaga. Yatsinze igenzura ryose ariko yananiwe gupima umunaniro. Intandaro yaturutse inyuma gutandukana gato muri Igikonoshwa inzira-idahuye rito mububiko bwibumba bwa ceramic byatumye habaho itandukaniro ryikigereranyo cyaho, bituma habaho zone ya microstructure itandukanye gato. Munsi ya microscope, yagaragaye. Munsi yumuzigo, byari ingingo yamenetse.
Niyo mpanvu inzira igenzura ibintu birenze ubugenzuzi bwa nyuma kubintu bikomeye. Ntushobora kugenzura ubuziranenge mubice; ugomba kuyubaka uhereye ku ntambwe yambere yo gukora ifu. Abatanga isoko babona ibi, nka QSY hamwe nigihe kirekire cyibanda kubikorwa aho gusohora gusa, bakunda kugira bike muribi byago, byananiranye. Amateka yabo yimyaka 30 yerekana ko babonye - kandi bakemuye ibibazo nkibi mbere.
Ikindi kintu gisanzwe, kunanirwa ni galvanic ruswa mu nteko. Gukoresha icyuma kitagira ingese mumazu ya aluminiyumu kububoko bwa skaneri yoroheje bishobora gusa nkaho ari byiza, ariko imbere yabantu bamwe bakora isuku, birashobora gushiraho ingirabuzimafatizo. Igice ntikinanirwa ako kanya; birananirana nyuma yamezi yo gukoresha, akenshi hanze yigihe cya garanti. Isesengura ryibikoresho bifatika murwego rwo gushushanya nintambwe idashobora kuganirwaho akenshi yirengagizwa.
Ubufatanye Bwuzuye
Amasoko ibikoresho by'ubuvuzi ibice ntabwo ari itegeko ryo kugura ibicuruzwa. Nubufatanye bwa tekiniki butangira kera mbere ya RFQ. Ibisubizo byiza bibaho mugihe uwashushanyaga ibikoresho yifatanije nabafatanyabikorwa mugukora icyiciro cya prototyping. Iyi mfuruka y'imbere irashobora gukwirakwira gato kugirango itezimbere ubuzima bwibikoresho bitabangamiye imikorere? Ubunini bwurukuta bushobora gukorwa kimwe kugirango wirinde kurohama?
Umufatanyabikorwa ufite ubushobozi bwuzuye - kuva kuri casting kugeza Imashini ya CNC- itanga ibitekerezo byuzuye. Bashobora gutanga inama ko igice cyateguwe nkigikoresho cyo gusudira gishobora gukorwa neza cyane nkigice kimwe cyo guteramo imashini ntoya yo kurangiza, kunoza ubunyangamugayo no kugabanya ingingo zishobora kwanduza. Ubu bwoko bwigishushanyo-cyo-gukora-kwinjiza ni ntagereranywa kandi biva muburambe-ngiro mubikorwa byose byakozwe.
Kurangiza, intego ni iyo kwizerwa mumurima. Igice ntabwo ari ikintu kiri kuri fagitire y'ibikoresho; nibigize mubikoresho umuganga yishingikirizaho. Iyo myumvire ihindura uburyo wegera kwihanganira, buri buso burangiza guhamagarwa, hamwe nicyemezo cyibikoresho. Yimura akazi kuva mubihimbano byoroshye kugeza umusanzu wakozwe. Kandi ibyo, amaherezo, nibyo bitandukanya utanga ibicuruzwa nabafatanyabikorwa nyabo bakora inganda zubuvuzi.
