Iyo ubajije ikiguzi cyo gushora imari, abantu benshi basimbuka neza kubiciro kuri buri gice. Iri ni ikosa rya mbere. Igiciro nyacyo ni urubuga rwibyemezo, ubwumvikane, kandi rimwe na rimwe, imitego ihishe wiga gusa nyuma yuko umushinga ujya kuruhande. Ntabwo ari ibyerekeranye n'uburemere bw'icyuma gusa cyangwa igice kigoye ku gishushanyo; bijyanye nibintu byose bibaho kuva urangije igishushanyo kugeza umunsi wakiriye pallet ya casting yarangije. Nabonye imishinga myinshi aho amagambo yambere yasaga neza, gusa kumafaranga yakoreshejwe kuri ballon kuko ntamuntu wabajije ibibazo bikwiye imbere.
Aho Amafaranga Ajya
Reka tubice. Ibintu binini byamatike biragaragara: ibikoresho nakazi. Ariko muri ibyo, guhitamo amavuta ni umushoferi munini. Kujya hamwe na 316 isanzwe idafite isi ni isi imwe; kwerekana nikel ishingiye kuri superalloy nka Inconel 718 niyindi sanzure ukurikije igiciro cyibikoresho nubuhanga bukenewe kugirango tuyitere neza. Ntabwo uriha gusa ibyuma bihenze cyane; urimo kwishyura ubushobozi bwububiko bwo kubikemura utarinze gukora igipimo kinini, cyanzanye kumwanya ukurikira.
Igikoresho cyo gukoresha igishushanyo cyibishashara gikunze kutumvikana. Kuri prototypes cyangwa umubumbe muto cyane, urashobora gukoresha 3D-icapishijwe ibishushanyo, bizigama kubikoresho byambere ariko byongera igiciro cyibice kuri buri gishashara. Kugirango umusaruro ukorwe, ukeneye aluminium cyangwa icyuma. Nicyo kiguzi cyambere cyo gukoresha amafaranga. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu muri gushora imari no gutunganya, mubisanzwe byatanga inama kuriyi ngingo-niyo ngingo. Urubuga rwabo, tsingtaocnc.com, yerekana akazi kabo hamwe na alloys idasanzwe, ihita ikubwira ko bashizweho kumirimo aho ibikoresho nibikoresho byo kugenzura birenze ibikoresho.
Noneho hariho uburyo bwo kubaka igikonoshwa ubwacyo. Umubare w'amakoti ya ceramic, igihe cyo kumisha hagati ya buri, ubwoko bwa stucco yakoreshejwe - ibi byose mubikorwa byakazi nigihe cyakazi. Igice kitoroshye gifite umufuka wimbitse gishobora gukenera amakoti arindwi cyangwa umunani, mugihe imiterere yoroshye igera hamwe na gatanu. Buri kote yongeraho umunsi mukuzenguruka. Noneho igiciro cyo gushora imari ihujwe neza nigihe igice cyawe gifata umwanya mubyumba byumye.
Abashoferi Bihishe Abashoferi (Abakubona)
Aha niho havugwa uburambe. Ubuso bwo kurangiza ibisabwa. Niba ukeneye as-guta hejuru ya 125 Ra microinches, ibyo nibisanzwe. Ariko niba spike yawe ihamagarira 63 Ra cyangwa nziza, uruganda rugomba guhindura ceramic slurry, gukoresha stucco nziza, kandi birashoboka gukora byinshi nyuma yo kurangiza. Ihinduka ryihariye rishobora kongera 15-20% kubiciro byawe byoroshye. Nibisobanuro bikunze kwirengagizwa kubishushanyo mbonera.
Gate na venting igishushanyo nubundi bwicanyi bwicecekeye. Sisitemu mbi yo kwinjirira yabugenewe kugirango ibike ibintu irashobora gukurura imivurungano, guhumeka ikirere, no kugabanuka kwinshi. Igisubizo? Igipimo cyo hejuru. Wazigamye $ 2 ku gishashara ariko ubu ufite igipimo cyo kwangwa 30%. Ukuri igiciro cyo gushora imari ku gice cyiza cyazamutse cyane. Nize ibi inzira igoye kumushinga hakiri kare kuri pompe; twahinduye igishushanyo mbonera cyo gukoresha ibishashara bike, ariko icyiciro cya mbere cyari gifite 40% yo gutsindwa kubera kugabanuka. Tugomba kongera gushushanya amarembo yose, bivuze ibikoresho bishya no gutinda amezi abiri.
Ibikorwa bya nyuma ya casting byavuzwe kenshi ukundi. Igiciro kirimo gukata (gukuramo ibice ku giti)? Harimo gusya amarembo? Bite ho kuvura ubushyuhe cyangwa kugorora? Serivisi yuzuye itanga serivisi Imashini ya CNC, nkuko QSY ibivuga muri intro zabo, irashobora koroshya ibi. Kugira guta no gutunganya munsi yinzu imwe bigabanya ibikoresho, kongera guhuza, hamwe nibibazo byamaboko meza. Uku kwishyira hamwe kurashobora kugabanya igiciro cyawe cyubutaka, nubwo amagambo yambere yo gutora atariyo ahendutse rwose kumasoko.
Umubumbe na complexe: Itegeko riringaniza
Gushora imari bizwi cyane kuri geometrike igoye, ariko bigoye bifite igiciro. Igice gifite inkuta zoroheje (vuga, munsi ya 2mm) gisaba gutera ibishashara neza no kubaka igikonoshwa kugirango wirinde kumeneka cyangwa kuzura kutuzuye. Imbere yimbere yongeramo urundi rwego rwibiciro hamwe ningaruka. Kubijwi rito, birashobora kuba byiza kongera gushushanya kugirango wirinde intangiriro. Kubunini bwinshi, ikiguzi cyibanze kiba kigabanijwe.
Aha niho ubufatanye bwigihe kirekire bufite akamaro. Uruganda rwumva inganda zawe rushobora gutanga igishushanyo mbonera-cyo gukora (DFM) impinduka hakiri kare. Urebye QSY yibanze kuri shell mold na gushora imari hirya no hino mubikoresho bitandukanye, biragaragara ko bigamije gukemura ibyo bicuruzwa bigoye. Bashobora kuba baragiriye inama abakiriya batabarika aho bongeramo umushinga muto cyangwa radiyo kugirango umusaruro wiyongere.
Kugabanuka kwijwi birahari, ariko ntabwo ari umurongo. Igiciro kinini cyagabanutse kibaho kuva prototype (ibice 1-10) kugeza kumusaruro muto (ibice 100-500). Nyuma yibyo, kuzigama kuri buri gice bigabanuka. Urimo kubika cyane kubikoresho byahinduwe hamwe nigihe cyo gushiraho. Imirimo n'ibikorwa bitaziguye kuri buri gice bihinduka ibintu byiganje.
Guhitamo Ibikoresho: Ikigereranyo Cyibiciro
Ntushobora kuvuga ikiguzi utiriwe uvuga ibikoresho. Ibyuma bya karubone nibyo shingiro. Ibyuma bitagira umwanda (304, 316, 17-4 PH) ni intambwe yo kuzamuka. Ariko iyo winjiye kurutonde rwa cobalt cyangwa nikel-ishingiye kuri nikel QSY, uba uri muri shampiyona itandukanye. Aya mavuta ntabwo ahenze gusa ku kilo, ariko kandi biragoye gushonga, gusuka, no kurangiza. Bakenera uburyo bukomeye bwo kugenzura no kuvura ubushyuhe bwihariye.
Igiciro cyo gukoresha aya mavuta ntabwo ari ikintu cya fagitire gusa. Nibyiringiro ko uruganda rufite ubuhanga bwibyuma byo kubungabunga imitungo. Uruganda ruhendutse rushobora gutanga Inconel, ariko niba batagenzura ubushyuhe bwo gusuka cyangwa ukwezi gukonje neza, urangiza ufite igice gisa neza ariko cyananiranye muri serivisi. Nicyo giciro cyanyuma, catastrophique.
Rimwe na rimwe, guhitamo neza ni ugukoresha ibikoresho bihenze kuva mugitangira. Ndibuka ibice bigize valve byerekanwe muburyo busanzwe butagira umwanda. Yakomeje kunanirwa munsi ya ruswa. Twahinduye murwego rwohejuru duplex idafite ingese, yikubye kabiri ibikoresho igiciro cyo gushora imari. Nyamara, ubuzima bwibigize ubuzima bwikubye inshuro eshanu, bigatuma igiciro cya nyirubwite kiri hasi cyane. Umufatanyabikorwa mwiza wo gushinga agufasha kubona iyo shusho nini.
Kugera kumagambo afatika
None, nigute ushobora kubona amagambo yerekana ukuri? Tanga byose. Moderi ya 3D ni intangiriro, ariko ntibihagije. Ugomba kwerekana: icyiciro cyibikoresho (ntabwo ari ibyuma bidafite ingese gusa), ibikoresho bya mashini bisabwa, kuvura ubushyuhe, ibipimo byemewe byemewe (nka ASTM A802 yo kugenzura hejuru), nibikenewe nyuma yo gutunganywa. Uko udasobanutse neza, niko ibihe byihutirwa uruganda ruzubaka mubiciro kugirango bishyure ingaruka zabo.
Saba gusenyuka. Ijambo risobanutse rishobora gutandukanya igiciro cyibikoresho, igiciro cyo guta, hamwe nigiciro cyo gutunganya. Ibi biragufasha kumva aho amafaranga agana naho hashobora kuba umwanya wo kuganira cyangwa gusubiramo.
Hanyuma, suzuma agaciro kose, ntabwo ari igiciro gusa. Uruganda rufite intego Imashini ya CNC ubushobozi, nkubwavuzwe kuri tsingtaocnc.com, itanga kugenzura. Bakora inzira yose kuva icyuma gishongeshejwe kugeza kumashini, yiteguye-gushiraho igice. Ibi bigabanya umutwaro wawe wubuyobozi, byoroshya gukurikirana ubuziranenge (ingingo imwe yinshingano), kandi akenshi biganisha kumurongo mwiza muri rusange kuko itsinda ryimashini ryumva inzira yo gukina. Uku kwishyira hamwe bifite agaciro amagufa yambaye ubusa kuri kilo casting cote ntizigera yerekana. Amaherezo, ukuri igiciro cyo gushora imari ni igiciro cyo kubona igice cyizewe, gikora cyujuje ibisobanuro byawe byose, mugihe, buri gihe. Ibindi byose ni ikigereranyo gusa.
