Iyo wunvise 'Precision Sand Casting', ishusho ihita irashobora kuba iyikomeye, hafi-net-shusho. Ibyo ni bimwe mu bigize, ariko ikintu nyacyo - kandi aho usanga ibintu byinshi bibeshya - ni ukumva ko 'precision' hano iterekeye kwirukana kwihanganira urwego rwa micron nko mu gushora imari. Byerekeranye no kugenzurwa, gusubiramo geometrie hamwe nubusugire bwubuso muburyo bukomeye cyane mumiryango imwe n'imwe. Umutego usanzwe urimo kubifata nkuburyo buhendutse bwo gushushanya ibishashara cyangwa ibishashara byatakaye, mugihe mubyukuri ari igisubizo cyihariye cyo kubyara umusaruro wibintu bito-bigoye aho umutekano uhagaze hamwe nijwi ryimbere bitaganirwaho.
Ubworoherane Bwatahuwe
Ndibuka umushinga mumyaka yashize kumubiri wa hydraulic valve. Igishushanyo cyahamagaye ± 0.5mm kuri bore centre zikomeye. Umukiriya yabanje gusunika gushora imari, yibwira ko aribwo buryo bwonyine. Twaganiriye ku mucanga utomoye - dukoresheje sisitemu ishingiye kuri zircon hamwe nuburyo bugenzurwa cyane. Amayeri ntabwo yari umucanga gusa; byari ibikoresho by'icyitegererezo, igishushanyo mbonera, hamwe no gukira gukomeye. Twakubise ± 0.4mm buri gihe, ariko cyane cyane, ubunyangamugayo bwumuvuduko bwari hejuru kubera imiterere yingano nziza twagezeho. 'Ibisobanuro' byari mu kugenzura inzira, ntabwo ari ibikoresho byo gutangira gusa.
Iyo iguye mugufi, mvugishije ukuri, ni kurukuta ruhebuje. Niba ugerageza kujya munsi ya 3mm kuri casting nini, uri muri shell cyangwa agace k'ishoramari. Sisitemu ya binder mumusenyi utomoye ifite imipaka kubitemba. Nabonye ibishingwe bigerageza kubisunika, bikavamo amakosa yibeshya asa neza kuruhande rumwe kandi arasenyutse kurundi ruhande. Nimbogamizi yibintu ugomba kubaha.
Ibi bihuza nibyo iduka nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ryashimangira hamwe nimyaka mirongo itatu yo gukina. Bashyiraho urutonde rwibishishwa hamwe nishoramari ritandukanye kubwimpamvu. Iyo ukorera mubikorwa, utezimbere kumva neza aho buri kimwe gihuye. Ibikorwa byabo byigihe kirekire byerekana ko babonye ikiguzi cyo gukoresha nabi-aho guhatira igice mubikorwa bitari byiza biganisha kumayira cyangwa kugiciro cyinshi cyo gukora nyuma.
Ibyingenzi: Binders na Sisitemu
Umutima wibikorwa ni binder-sand chemistry. Fenolike urethane agasanduku gakonje nakazi ko gukoreramo, ariko 'precision' akenshi ituruka kumusenyi ubwawo. Silica ni ibisanzwe, ariko kubicyuma cyangwa ubushyuhe bwo hejuru cyane, kwimukira kuri chromite cyangwa umucanga wa zircon ni umukino uhindura umukino wo gusubiramo. Coefficient yo kwagura ubushyuhe iri hasi. Kwaguka gake mugihe cyo gusuka bisobanura kugabanuka kwa geometrike. Birahenze cyane, kuburyo utabikoresha kubifuniko bya manhole, ariko kububiko bwa pompe muri duplex idafite umwanda? Icyangombwa.
Ibi twabyize inzira igoye kumurongo wamapompe muri CF8M. Twifashishije silika isanzwe, twagize ibibazo byo kugabanuka kumurongo wicyuma, bisaba gusanwa cyane. Yahinduwe muri sisitemu ya zircon, yongeye gushushanya ibiryo bito, kandi igipimo cyo gukuraho cyamanutse kiva kuri 15% kigera munsi ya 2%. Igiciro cyumucanga cyazamutseho 40%, ariko igiciro cyose cyagabanutseho 18%. Ubwo ni bwo buryo bwo kubara busobanura ibintu nyabyo byo guta umucanga.
Ntabwo ari amarozi. Ikigereranyo cya binder, igihe cya gaze, isuku - buri segonda ibara. Ifumbire idakize izakaraba. Umuntu ukize cyane aba acitse intege kandi ashobora gutera inclusitions. Ubuhanga buri mukuyihamagarira mugice cyihariye cya geometrie na alloy. Aha niho uburambe, nkubwo bwubatswe mukigo nka QSY, gihinduka gifatika. Ntushobora gukoresha urwo rubanza.
Kwinjira no Kugaburira: Ubwubatsi butagaragara
Aha niho moderi ya CAD isa ntakintu kimeze nkicyuma cyanyuma. Irembo ryumucanga utomoye akenshi rirakaze kuruta umucanga wicyatsi. Ukeneye kuzura byihuse kugirango ukoreshe neza isura nziza yo kurangiza. Ariko kuzura byihuse birashobora gusobanura imvururu. Dukoresha ceramic muyunguruzi mumadini ubungubu-byoroshye byoroshye byashyizwe mubiruka. Yongeraho ikiguzi, ariko kugabanuka kwa okiside, cyane cyane muri alloys nka nikel ishingiye kuri nikel, biratangaje. Ntabwo ari ibiganiro byigice icyo aricyo cyose kigenewe gupakira ibintu.
Kugaburira igishushanyo nubundi buhanzi bworoshye. Imbaraga zisumba izindi zikize bivuze ko zirwanya umuvuduko wicyuma cyane, zishobora rwose kubuza kugaburira niba utitonze. Rimwe na rimwe ukenera ibiryo binini cyangwa byinshi muribyo ugereranije numusenyi wicyatsi kubice bimwe. Ndibuka ibikoresho bikikijwe n'inkuta zambaye ubusa aho twandukuye ingano ya federasiyo uhereye kumusenyi wicyatsi. Byarangiye hamwe na cavit nini yo kugabanuka kuri hub. Byabaye ngombwa ko usubira inyuma, wongere modulus yo kugaburira ijosi, hanyuma wongereho amaboko ya exothermic kugirango ukomeze gushyuha igihe kirekire. Byakemutse. Nibikorwa byo gukosora bigenda bitekwa mubikorwa bisanzwe.
Urebye urutonde rwibintu kuva Qingdao Qiangsenyuan Technology Co., Ltd.-Imisemburo idasanzwe, ishingiye kuri cobalt, nikel-uzi ko bagomba kumenya ibi. Ayo mavuta afite ibiranga kugaburira nabi. Kubona amajwi muri bo hamwe n'umucanga utomoye ni ukwemeza gukomeye ubushobozi bwa tekiniki.
Amafaranga yo Kumashini: Imigaragarire
Iyi ni ingingo nkuru yo kugurisha. Igikorwa cyumucanga gikora neza kirashobora kugabanya ububiko bwimashini kugera kuri 1.5-2mm kumaso, rimwe na rimwe ndetse na 1mm hejuru yumwanya uhamye. Nibyo isafuriya nini cyane mugihe cya CNC no kwambara ibikoresho. Ariko ntabwo byemewe. Amafaranga agomba kumvikana ashingiye kumiterere yihariye. Ubuso bunini? 1.5mm irashobora kuba nziza. Kurenga umurongo wo gutandukana cyangwa hafi yintangiriro? Urashobora gukenera 3mm. Nagize umuhamagaro mwinshi mububiko bwimashini mugihe icyiciro cyinjiye hamwe nicyo babona 'ububiko budahagije', gusa nasanze itandukaniro ryavuye kumurongo wibanze tutigeze tubara bihagije.
Ubufatanye no gutunganya ni ingenzi. Niyo mpamvu ibikorwa byahujwe, nkiki QSY ibyerekanwe hamwe hamwe na serivisi yo gutunganya CNC hamwe, bifite akarusho. Itsinda ryabo ryimashini rigaburira amakuru yimibare itaziguye. Iyo funga ifunze itanga uburyo bwo gukomeza gukomera. Niba gutora no gutunganya biri mubigo bitandukanye, ibyo bitekerezo akenshi biratinda, byungururwa, na politiki.
Twashyizeho itegeko ryoroshye: raporo yambere yo kugenzura ingingo kuva mubukorikori ijya mubikorwa bya injeniyeri, ntabwo kugurisha gusa. Kugabanya amakimbirane yimfashanyo yo gutunganya 70% mumwaka. Byatumye abantu bose bavuga ururimi rumwe rwa datum nibiranga gupimwa.
Iyo binaniwe, n'impamvu
Kunanirwa birigisha. Ikintu gikunze kugaragara mbona ni ugukurikirana-izo nenge zisa na fin ku buso. Mubisanzwe ntaho bihuriye no kwaguka kwumusenyi nimbaraga zishyushye. Rimwe na rimwe birakosorwa muguhindura amanota yumucanga; rimwe na rimwe bisaba guhinduka kuri ratio ya cataliste. Ni akazi k'iperereza.
Kunanirwa gukabije ni urukuta rwimbere mugihe cyo gusuka, biganisha ku makosa akomeye. Nibisanzwe hafi yicyitegererezo cyangwa agasanduku k'ibanze-ibikoresho byambarwa, inkunga idahagije. Nibibazo byingenzi, ntabwo ari inzira imwe. Uruganda rukora ibintu bishaje ntibishobora gutanga guta umucanga, igihe. Iki nikimenyetso gituje cyubuzima bw iduka. Niba usuye ukabona ibikoresho byiza, byubatswe neza, ni ikimenyetso cyiza. Niba ibishushanyo byaciwe kandi bifashwe hamwe na kaseti, genda.
Kuramba byerekanwa namateka ya QSY yimyaka 30 byerekana ko bayoboye uruziga rukuru. Kugumana imiterere yukuri mumyaka mirongo yumusaruro kubakiriya banyuranye nubushobozi bwibanze butagaragara kurupapuro rwihariye.
Niche-Isi
None, uyu munsi yicaye he? Ntabwo ari prototyping-igiciro cyikigereranyo ni kinini cyane. Ntabwo ari kubice byoroshye - umucanga wicyatsi uhendutse. Ikibanza cyacyo kiryoshye ni hagati-hejuru-hejuru (ibice 500-10,000 buri mwaka) ibice bikenera kugenzurwa neza no kurangiza kuruta umucanga wicyatsi ushobora gutanga, ariko ntibifite ibisobanuro byiza cyane cyangwa urukuta ruto rutegeka gushora imari. Tekereza amazu ya compressor, imibiri ya valve, agasanduku gaciriritse gaciriritse, hydraulic manifolds.
Ibikoresho byoroshye ni inyongera nini. Kwimuka uva mucyuma kijugunywa kuri nikel ishingiye kuri nikel akenshi bisaba gusa guhindura sisitemu yumucanga no guhindura imicungire yubushyuhe mubibumbano. Inzira yibanze yibikorwa iracyahari. Iyi mpinduramatwara niyo mpamvu inganda nyinshi zishyizwe hamwe, cyane cyane abakorera ingufu n’imashini ziremereye, bishingikiriza.
Amaherezo, guta umucanga ni gihamya yubwumvikane buke. Yemera ubunini bwibanze bwumucanga kugirango ibone ubunini nuburinganire bwimiterere, hanyuma ikoresha chimie, imicungire yubushyuhe, hamwe nuburyo bukomeye bwo kugenzura kugirango sisitemu igere kumipaka ihamye. Ninzira kubashakashatsi bumva ko gukora ari uguhitamo igisubizo gikomeye, ntabwo aricyo gifite numero ifatanye kumpapuro. Urwo ni urubanza ruva gusa kubona ibice bigenda neza, bikananirana, kumaduka kumyaka.
