Gutera umucanga bikomeje gukoreshwa cyane muburyo bwo gukora ibyuma-bingana na 70% bya casting zose zakozwe ku isi. Ariko kubashya bakandagira mumushinga, ubwinshi bwa ibice byo guta umucanga irashobora kumva bikabije. Ibishushanyo, kwihanganira no gukurura, amasoko, risers, cores, amarembo - buriwese afite uruhare rutavugwaho rumwe mugukina amajwi kugaragara cyangwa gusakara.
Twabonye abantu benshi ba injeniyeri ba mbere bahuza umurongo wo gutandukana mugihe cyo guterana. Twarebye abatekinisiye b'inararibonye birengagiza gushyira imishinga-bikarangira umufuka wa gaze mumibiri ya hydraulic. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Aho dukora ibyuma bisobanutse neza nibyuma byamazu ya pompe yumuvuduko mwinshi hamwe na cobalt-alloy nozzles, buri kintu cyose kigize umucanga kirasuzumwa-ntikigaragara. Reka dusenye ibyingenzi ibice byo guta umucanga, ntabwo nkibisobanuro byibitabo, ariko nkibintu bikora twishingikiriza burimunsi kugirango dutange ibice bifite umuvuduko wa 350+ utarinze kumeneka.
Ibice Byibanze Ugomba Gusobanukirwa Mbere yo Gusuka
Umucanga wo guta umucanga ntabwo ari umucanga wuzuye. Nuburyo bwa sisitemu yakozwe neza igamije kugenzura ibyuma, kugaburira gukomera, no kurekura imyuka yafashwe. Dore ibice bitanu bidashobora kuganirwaho-kandi bigenda bite iyo umuntu ananiwe:
- Icyitegererezo: Igereranya ryuzuye ryigice cyanyuma - mubisanzwe bikozwe mubiti, plastike, cyangwa aluminiyumu yakozwe. Ukuri kwayo gusobanura mu buryo butaziguye kwihanganira ibipimo. Dukoresha CNC yakozwe na aluminiyumu yububiko bwa silinderi kuko ifata mm 0,15 mm hejuru ya mm 400 z'uburebure - birakomeye mugihe utunganya ibimenyetso bifunga kashe nyuma.
- Guhangana no gukurura: Hejuru (cope) no hepfo (gukurura) ibice bibiri. Imigaragarire yabo ni umurongo wo gutandukana. Kudahuza hano bitera flash igomba guhagarara - intambwe ihenze yo gukora twirinda dukoresheje kwiyandikisha kwa dowel-pin kumurongo wose wakozwe.
- Isoko: Umuyoboro uhagaze unyuzamo ibyuma bishongeshejwe byinjira mu cyuho. Biragufi cyane? Imivurungano yongera okiside. Mugari cyane? Kugaburira nabi. Kubice byacu bya T800 cobalt alloy pompe, turapima amasoko dushingiye kubiharuro byumutwe wa metallostatike - ntabwo ari amategeko-yerekana-igikumwe.
- Riser: Ikigega cyashyizwe hejuru cyangwa kuruhande rwa casting kugirango kigaburire kugabanuka mugihe cyo gukomera. Ikosa risanzwe: gushira ahabona ibyago kubice byinshi. Mu cyiciro kimwe cyamazu ya pisitori ya pisitori, ingano ya riser idahagije yatumaga umurongo wo hagati ugaragara gusa mugihe cyo kugenzura ultrasonic. Noneho twigana gukomera hamwe na MAGMAsoft mbere yo guhimba ibumba.
- Core: Umucanga utandukanye winjizamo imyenge yimbere-nkibice bikonje cyangwa bore ya valve. Cores igomba kwihanganira umuvuduko wa metallostatike hamwe nubushyuhe bwumuriro. Dukoresha imiti ihujwe na silika umucanga hamwe na furan resin kugirango imbaraga zingenzi, hanyuma dutekeshe kuri 220 ° C muminota 90. Intanga zidapfunyitse zisenyuka munsi ya 1,450 ° C icyuma gishongeshejwe.
Impamvu Igishushanyo cy'Irembo gitandukanya imyizerere yizewe
Amarembo - imiyoboro ihuza amasoko nu mwobo - ntibikunze kuganirwaho, nyamara bigena ubusugire bwubuso, imiterere yingano, hamwe nogusaranganya. Bamwe bashobora gutongana amarembo ni iyakabiri kubishushanyo mbonera. Ariko, mubyatubayeho hamwe na AMS 5387 cobalt alloy ibice 6, gutambuka bidakwiye bitera kunanirwa inshuro eshatu zisubirwamo: gufunga ubukonje hafi yinkuta zoroshye, isuri yumusenyi muri zone yihuta cyane, hamwe no kwinjirira imyanda aho binjirira.
Twifashishije epfo-ruguru kumazu maremare, yubatswe n'inkuta kugirango tugabanye imvururu. Kubice bisa nkibikoresho bya winch center shaft, dukoresha amarembo menshi ya radiyo - tureba kuzuza kimwe no gukomera kwerekeza kuri risers. Buri marembo yambukiranya ibice abarwa hifashishijwe ihame rya Bernoulli ryahinduwe kugirango ibyuma byijimye kandi bigabanuke. Ntabwo aribyo bitekerezo-nuburyo tugera kuri Cpk> 1.33 kuri diametre zikomeye hejuru ya 500+ ikora.
Ibyo Abitangira Kwirengagiza: Ibicuruzwa, Gutandukana Umusenyi, na Shakeout Igihe
Ibicuruzwa ni utwobo duto - akenshi ni mm2-22 z'umurambararo - byacukuwe muri cope cyangwa gukurura kugirango umwuka hamwe na gaze ibumba. Simbuka, hanyuma ubone pinholes cyangwa blowholes. Ducukura imyanda y'intoki nyuma yo guteranya ibishushanyo, tukabishyira ahantu haheruka-kuzura byagaragaye mu kwigana. Nta automatisation - kubera ko ibikoresho byambara bihindura umwobo geometrie, hamwe no guhumeka bidahuye byangiza microstructure.
Gutandukanya umucanga - urwego rwiza rwuzuye umukungugu hagati ya cope no gukurura - rugomba kuba rwumye, rutemba-ubusa, kandi ntiruhuza. Dukoresha ifu ya alumina yabazwe, ntabwo ari grafite. Graphite ihindura ubushuhe muburyo bwimikorere kandi igateza imbere inenge zifata ibyuma bidafite ingese.
Shakeout igihe cyingirakamaro kuruta uko benshi babibona. Kuraho ibishishwa hakiri kare bitera ubushyuhe bwumuriro - cyane cyane mubyuma bya karubone. Biratinze cyane, kandi ubushyuhe busigaye butera kugoreka mumashini yerekanwe. Igipimo cyacu: gukonjesha ikirere kugeza ubushyuhe bwo hejuru bugabanutse munsi ya 150 ° C, bigenzurwa na metero ya IR ya termometero - ntabwo ari igihe.
Kuva Mubibumbano Kuri Inshingano-Igice Cyingenzi: Aho Gutera Umucanga Bikwiranye Uyu munsi
Gutera umucanga ntabwo ari tekinoroji yumurage-ni umusingi wo gukora imvange. IKORANABUHANGA RYA QINGDAO QIANGSENYUAN, duhuza ibishishwa byumucanga hamwe na CNC ikora imashini nyinshi, gutunganya ubushyuhe, no kurangiza hejuru - byose munsi yinzu imwe yujuje ISO. Uku kugenzura guhagaritse kutwemerera kwemeza GD&T kubahiriza ibintu nko kwibanda kuri bore-to-flange (± 0,05 mm) cyangwa ubukana bwa Ra ≤0.8 µm kumaso.
Niba urimo kwerekana igitutu cyamazu cyangwa ibinyabiziga bya winch ibice, gusobanukirwa na ibice byo guta umucanga bivuze kumenya aho kwihanganira gutondekanya, aho inenge zikomoka, nuburyo guhitamo ibishushanyo bigira ingaruka kubiciro no kuyobora igihe. Bisobanura kubaza ntabwo “Birashobora guterwa?” ariko "Ni gute buri kintu kigize imyitwarire kizitwara kuri 1,520 ° C hamwe nigihe cyo gusuka amasegonda 12?"
Ngiyo itandukaniro riri hagati yo gushushanya no gutangwa. Niyo mpamvu abakiriya bacu-kuva muri Amerika ya ruguru kugera mu majyepfo yuburasirazuba bwa Aziya-batwoherereza ibishushanyo bya GD & T bikungahaye hamwe na metallurgical spes, ntabwo ari ibishushanyo gusa. Kuberako bazi ifumbire ntabwo ari kontineri gusa. Nicyiciro cya mbere cyo kugenzura ubuziranenge.
