Iyo abantu benshi bumvise 'ibyuma bitagira umuyonga wabuze ibishashara', bashushanya ikintu kitagira inenge, kibengerana neza kiva muri ako gatabo. Ngiyo imyumvire ya mbere itari yo. Ukuri kurangaye cyane, kurushijeho gukomera, kandi bikubiyemo gukemura ibibazo nkuko bikorwa. Ntabwo ari ugukora ishusho gusa; ni ukugenzura impinduka ijana kugirango ubone igice gikora cyujuje urupapuro rwuzuye rwuzuye imibare - imbaraga zingana, kurwanya ruswa mubidukikije runaka, amanota yumuvuduko. Igice 'kitagira umwanda' ni hafi gutukura; amanota afite akamaro kuruta umuryango. 304, 316, 17-4PH - buriwese yitwara nabi mugihe uyisutse kuri 1500 ° C mumashanyarazi. Aho niho imirimo nyayo itangirira.
Umukino wa Shell: Byose mubibumbano
Reka tuvuge kubyerekeye igikonoshwa. Ibi ntabwo ari ibishushanyo mbonera. Nintwaro nyinshi zubutaka bwububiko bwubatswe mugushira ibishashara mumashanyarazi na stuccos. Umubare w'amakoti, igihe cyo gukama hagati ya buri, ubushuhe bw’ibidukikije - kubona kimwe nabi kandi igikonoshwa gishobora guturika mugihe cyo gutemba (gutsindwa bidasanzwe, kunanirwa) cyangwa ntigikomeye bihagije kugirango kirimo icyuma gishongeshejwe, biganisha kubyo twita 'gushira'. Nabonye igishashara cyiza cyamazu ya pompe cyangiritse kuko ikote rya gatatu ryumye vuba mugihe cyicyumweru kidasanzwe. Igikonoshwa cyasaga neza, ariko cyari gifite micro-crack. Mugihe cyo gusuka, byari nkibishishwa. Igihombo cyose.
Aha niho uburambe buva kumaduka nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) yerekana. Hamwe nimyaka irenga 30 gushora imari, batetse ubu buryo bwubumenyi mubikorwa byabo. Ntabwo ari mu gitabo; ni mubyumutekinisiye yunva uburyo ibitonyanga bitonyanga, isura yikuma. Urubuga rwabo, tsingtaocnc.com, urutonde rwibishishwa byerekana nkibintu byingenzi kubwimpamvu. Nintambwe y'ifatizo. Urashobora kugira amavuta meza, ariko niba igikonoshwa cyawe cyananiranye, urimo usuka hasi ibyuma bihenze.
Inzira ya dewaxing ubwayo irakomeye. Benshi bakeka ko ushonga ibishashara gusa. Amaduka menshi cyane akoresha autoclave cyangwa flash dewaxing hamwe numuvuduko mwinshi. Ubushyuhe bwumuriro kuri shell ni bwinshi. Niba igikonoshwa sisitemu idahuye neza niyi ntambwe, izavunika. Ibi twabyize kare hamwe nibintu bigoye, binini cyane. Yahinduwe mubintu bitandukanye byo kwanga ikoti yambere, ikibazo cyakemutse. Nibintu bito, ibintu-urwego rwohindura rutandukanya igice cyakoreshwa nibisigazwa.
Guhangayikishwa nicyiciro: Guhitamo Iburyo butagira umwanda
Kugaragaza ibyuma bidafite ingese ni nko kugenda mububiko bwibikoresho no gusaba igikoresho. Ntacyo bivuze nta miterere. Kubikoresho byo mu nyanja, 316 nubusanzwe kuri molybdenum-yongerewe imbaraga zo kurwanya ruswa. Ariko nagize abakiriya bashimangira kuri 316 kubikorwa byimbere, byumye aho 304 byari kuba bihagije kandi bihendutse. Ugomba gusubiza inyuma, kwigisha.
Noneho hariho amanota-akomera amanota nka 17-4PH. Fantastic for high-strength, complex ibyuma bidafite ingese byatakaye ibishashara nk'imirongo yo mu kirere. Ariko ubushyuhe bwo kuvura cycle post-casting ntibababarira rwose. Impamyabumenyi nkeya kurugero rwubusaza, kandi ntubona ubukana bwa RC bwifuzwa. Igice gisa kimwe ariko kizananirwa mugupima. QSY kuvuga gukorana na alloys idasanzwe nka nikel ishingiye kuri nikel ambwira ko babonye ibi. Ibyo bikoresho birarenze. Igikorwa cyo gukina nigice cyambere cyurugendo; protocole yumuriro nubwa kabiri.
Ndibuka icyiciro cyimibiri ya valve muri CF8M (abakinnyi bahwanye na 316). Batsinze igenzura ryose ariko bananiwe gukora ikizamini gikomeye cyo kwangirika kubakiriya mu nganda zikora imiti. Ikibazo? Delta ferrite. Igipimo cyo gukonjesha mugikonoshwa cyari gito, gihindura microstructure. Twagombaga guhindura ubushyuhe bwo gusuka no guhindura imiterere ya shell-yongeramo fibre ceramic fibre yongeyeho ibice biremereye - kugirango dukonje. Ikibazo cyakemutse, ariko byasabye gusesengura metallurgical kugirango ubone intandaro. Igice cyasaga neza neza n'amaso.
Dimensional Tightrope: As-Cast vs Imashini
Imwe mungingo nini yo kugurisha ibishashara byatakaye ni hafi-net-shusho. Ijambo ryibanze ni 'hafi.' Umuntu wese usezerana ± 0.1mm kwihanganira hejuru yimiterere yikigice kimwe arambuye ukuri. Ugomba gucunga ibyateganijwe. Kugabanuka birahanurwa ariko ntabwo bihuye neza. Ikirebire, cyoroheje kizagabanuka muburyo butandukanye nubunini bunini kuri casting imwe. Igishushanyo gipfa kubara kuriyi, ariko burigihe hariho gutandukana.
Niyo mpamvu moderi yuzuye ya serivise yibigo bihuza casting na Imashini ya CNC birumvikana cyane. Kuri QSY, batondekanya byombi nka serivisi yibanze. Utera igice kugirango ubone geometrike igoye 90% ngaho, hamwe nububiko bwinshi kubutaka bukomeye bwo gushyingiranwa, insanganyamatsiko, no gufunga mumaso. Noneho, uyihuza ku ruganda rwa CNC cyangwa umusarani hanyuma ugakubita ibipimo nyabyo. Kugerageza kugera kuri ubwo bworoherane biturutse kumurongo ni ikosa ryibicucu kandi bihenze cyane mubijyanye no gukoresha no gutakaza umusaruro.
Twigeze kugerageza gutera ibikoresho bifite imikorere, nkuko byatewe amenyo kugirango tubike amafaranga yo gukora. Porotype yari nziza, ariko mubikorwa, itandukaniro ryumubyimba mumenyo yinyo mubice byinshi ntibyari byemewe. Isomo? Menya imipaka y'ibikorwa. Tera ibikoresho ubusa, koresha amenyo. Imikoranire hagati yinzira zombi -gushora imari kubintu bigoye, CNC kubisobanuro-niho agaciro nyako kakozwe kuri injeniyeri.
Abashoferi Bihishe Ibiciro: Kwinjira, Gutanga, no Kurangiza
Gusubiramo ibishashara byatakaye ntabwo bijyanye n'uburemere gusa. Igice cya 1kg cyarangiye gishobora gutangira nkigiti cya 3kg. Sisitemu yo kwinjiza no kwiruka, ihuza ibyuma, ni nini kandi igacibwa kandi ikongera gukoreshwa. Umusaruro wawe (uburemere bwigice cyarangije gusuka uburemere bwicyuma) nikintu kinini. Igishushanyo mbonera cyiza, gikunze kugereranwa na software ubu, ni ngombwa. Irembo ryateguwe nabi rirashobora gutera imivurungano, guhumeka ikirere, no kugabanuka kwinshi mubice byingenzi byigice cyawe.
Noneho hariho kurangiza. Nyuma yo kunyeganyezwa no gukata, ufite igice gitwikiriye ibisigisigi bya ceramic hamwe nibisumizi by'amarembo akomeye. Irakenera guturika, gusya, birashoboka koza imiti (gutoragura no gutambuka kugirango bitagira umwanda kugirango ugarure urwego rwa okiside irwanya ruswa). Ibi nibikorwa byinshi kandi akenshi birengagizwa mugutegura kwambere. Igice gifite ibice byinshi byimbere ni inzozi zo gusukura. Njye namaze amasaha nkoresheje amenyo hamwe nindege zamazi yumuvuduko mwinshi ngerageza kuvanaho ceramic yahujwe kumuyoboro ukonje. Noneho, dushushanya isuku kuva tugitangira.
Iki gikorwa cyanyuma-niho hasigaye ubukorikori bwinshi. Imashini zogusya zikoresha ni nziza kumiterere isanzwe, ariko inzu igoye, ifite imiterere-karemano? Ibyo akenshi bikenera gusya kabuhariwe hamwe nikiganza gihamye kugirango uhuze ubuso utiriwe ushakisha icyuma fatizo. Nubuhanzi.
Iyo bigenda neza: Kwishura
Nubwo kubabara umutwe, iyo ufashe neza, bigoye ibyuma bitagira umwanda byatakaye ibishashara igice - vuga, icyuma kimwe cya turbine icyuma gifite ibyuma bigoramye bidashoboka gukora imashini kuva ikomeye - birakwiye. Ubusugire bwigice kitagira gusudira cyangwa guhuza, ubushobozi bwo gukoresha amavuta-yimikorere ihanitse muburyo bukomeye, ubuso buhebuje burangiza bukenera kwitegura gake.
Ninzira isaba kubaha urunigi rwose, kuva inshinge zishashara kugeza ubugenzuzi bwa nyuma. Ntushobora kuba metallurgiste cyangwa umusore washinze cyangwa umukanishi. Ugomba kumva uburyo buri cyiciro kivuga ikindi. Nibyo impression mbona mubikorwa nkibi byasobanuwe kuri tsingtaocnc.com. Kumara igihe kirekire byerekana ko bakemuye izo mbogamizi zifitanye isano nibikoresho kuva kumyuma kugeza kuri nikel. Ubuhanga nyabwo ntabwo bwashyizwe kuri serivisi; ni ihamagarwa ryurubanza rwahamagaye hejuru yibihumbi bisuka, uhitamo uburyo bwo guhindura inzira kubutaha.
Ubutaha rero mugihe usuzumye casting, reba kumurika. Tekereza ku gishishwa cyayifashe, inzira yubushyuhe yafashe kugirango ikomere, ikigega cyibikorwa gisigaye cyo gutunganya, hamwe nintoki zahanaguye. Ngiyo inkuru yukuri yigice. Ibisigaye ni kwamamaza gusa.
