Urumva byinshi kubyerekeranye no kuramba muri gravity cast fer, ariko ibyinshi mubiganiraho bibura ingingo. Ntabwo ari ibijyanye gusa nicyuma cyangwa uburebure bwurukuta. Icyerekezo nyacyo, kuva aho mpagaze nyuma yimyaka mirongo itatu mumushinga, ni uguhinduka kuva gufata igihe kirekire nkicyerekezo gihamye cyo kugicunga nkimpinduka zikorwa, ziterwa cyane nimpinduka zidasobanutse mubuhanga no gufata ibyemezo nyuma yo gukina. Umuntu wese arashaka igice kimara iteka, ariko inzira ihari iragenda ihinduka.
Imyumvire mibi yibikoresho nkumwami
Iyo abakiriya babajije ibijyanye no kuramba, ikintu cya mbere basimbukira ni urwego rwibintu. Mpa Icyiciro cya 35 cyangwa cyiza. Nukuri, imbaraga zingirakamaro. Ariko nabonye imishinga myinshi cyane aho bagaragaza icyuma cyo murwego rwohejuru, hanyuma ukabangikanya nibindi byose murwego rwo kuzigama amafaranga make kuri buri gice. Chimie yashonze ihindagurika mugihe cyihuse cyo gusuka, gutera inshinge birihuta-mu buryo butunguranye, icyuma cyiza cyane cyuzuye grafite idakonje cyangwa karbide ikabije. Uwiteka imbaraga za rukuruzi sohoka kugerageza kugirango ugaragaze impapuro, ariko microstructure iroroshye. Bananiwe mumurima munsi yikizunguruka, kandi buriwese ashinja ibikoresho. Ntabwo yari ibikoresho; byari inzira ikikije ibikoresho.
Twagize ikibazo mumyaka mike ishize kumubiri wa hydraulic valve. Icyerekezo cyari gikomeye, gisaba ubunyangamugayo bwiza. Kwiruka kwambere byakoreshaga ibyuma bisanzwe byingurube-byingurube hamwe nubushyuhe bwitondewe hamwe na inoculant yihariye twateje imbere murugo. Ibice byatsinze ibizamini byose. Umunywanyi agabanya igiciro cyacu kuburyo bugaragara. Nyuma twaje kumenya ko bakoresheje icyuma cyo murwego rwohejuru ariko bagabanya inguni kubushyuhe bwubushyuhe no gusuka umuvuduko. Ibice byabo byatsinze ikizamini cya mbere cya hydrostatike ariko gitangira kwerekana micro-crack nyuma yikizunguruka 500. Ibyacu byari bigikora kuri 5000+. Umukiriya yagarutse. Isomo? Igisekuru cyicyuma ntigifite akamaro kuruta uko ubifata mugihe cya rukuruzi inzira.
Ibi biganisha kumurongo wambere wambere: kwibanda kubikorwa bihoraho nkumushoferi wibanze uramba. Nijyanye no kugenzura ibintu byose bihinduka-umubyimba w'ikoti, gusuka ubushyuhe bwa gradient, igipimo cyo gukonja mubibumbano-hamwe n'ishyaka ry'idini. Kwandika amakuru kumatanura yacu no kumirongo yo gusuka ntabwo aribyo kwerekana gusa; nuburyo dukurikirana ikibazo kiramba tugaruka kuri dogere selisiyusi 10 yubushyuhe bwa salle nyuma yo gusuka.
Aho Kuramba Byatsinze Cyangwa Byatakaye: Geometrie itagaragara
Kuramba ntabwo byakozwe kuri moderi ya CAD; yajugunywe mu gice. Iri ni ihinduka rikomeye mubitekerezo. Ba injeniyeri bashushanya imikorere, ariko akenshi bashushanya geometrike itera guhangayika mugihe cyo gukomera. Inguni zikarishye imbere, igice gitunguranye gihinduka-ibi byica biramba. Inzira mbona ni ubufatanye bwa hafi mbere yuko ikorwa. Turimo kumara umwanya munini kuri software yigana ntabwo twirinda gusa inenge zigaragara, ariko kugirango twerekane impungenge zumuriro mugihe cyo gukonja.
Kurugero, agace ka compressor iremereye. Igishushanyo cyari gifite imiterere myiza, ikiza ibiro. Ariko kwigana kwacu kwerekanaga amahirwe menshi yo guturika ashyushye ku mbavu. Twasabye kongeramo ibintu bike, ntabwo ari imbaraga zo gukoresha, ariko kubwimbaraga mugihe cyo kurema. Itsinda ryabashushanyije ryarwanyije - ryongeyeho uburemere buke. Twabyaye icyiciro kimwe nkuko kiri, hamwe nimwe twahinduye. As-is batch yari ifite igipimo cya 30% cyibisigazwa bivuye kumeneka igaragara gusa mugusuzuma irangi ryinjira. Icyiciro cyahinduwe? Hafi ya zeru. Uwiteka kuramba yo gutora amajwi yari asanzwe hejuru kuko yarokotse kuvuka kwayo nta nenge y'imbere.
Iyigana ryibikorwa rihinduka intambwe idashobora kuganirwaho kuri QSY. Nishoramari ryishura mukwirinda ibiza, inenge zihishe ziganisha kumurima. Yimura igihe kirekire.
Nyuma ya Casting Gambit: Kuvura Ubushyuhe no Gukora
Dore impaka. Shimangira ubutabazi. Amaduka amwe abifata nkigisanduku giteganijwe guterwa. Abandi barabisimbuka kugirango babike igihe n'imbaraga. Imyifatire yacu yarahindutse. Ubu turabibona nkigikoresho cyatoranijwe. Kubishusho bigoye, bifunze nkamazu ya pompe, nibyingenzi. Imyitwarire isigaye iturutse ku gukonjesha kutaringaniye irashobora kuba nini. Kureka guhagarika umutima ni nko guhinduranya isoko imbere mu gice; gutunganya bizayirekura, bitera kugoreka, kandi muri serivisi imizigo izakora kubintu byabanje gushimangirwa.
Ariko twagize kandi ibice birenze urugero. Ikintu cyoroshye, gifunguye-ikariso ikozwe mucyuma cyumuhondo cyaragabanutse byuzuye. Ntabwo byagabanije guhangayika gusa; yoroshya gato ibikoresho, igabanya kwihanganira kwambara ahantu h'ingenzi. Byari ikibazo cyo gukoresha resept isanzwe utabanje gutekereza. Noneho, duhitamo dushingiye kuri geometrie, uburebure bwurukuta, hamwe nubujyakuzimu bwa nyuma. Rimwe na rimwe, kubice bihamye, byoroshye, kugenzura gukonjesha mububiko birahagije. Porogaramu ihitamo ni inzira igana ubwenge, ntabwo ari byinshi, gutunganya.
Noneho hariho gutunganya. Igice cyiza cyane gishobora kwangizwa no gutunganya ubukana. Twahujije gutunganya CNC igice kugirango tugenzure iyi ntambwe yanyuma. Gufata uburemere, bwihuse kuri a icyuma igice kirashobora gushushanya matrise ya grafite hejuru, igakora urusobe rwa micro-fracure ihinduka ingingo yo gutangirira umunaniro. Abakanishi bacu bazi gukoresha igikoresho cya geometrike kandi igaburira / umuvuduko wa casting yacu. Ntabwo ari ugukubita urwego gusa; nibijyanye no kubungabunga ubunyangamugayo twakoze cyane kugirango dushinge munganda.
Amavuta yo Kuringaniza: Ntabwo Byose ari Superalloy
Buzz buri gihe kijyanye na exotic alloys. Ariko kubikorwa byinshi byinganda, inyungu ziramba zivanze no kuvanga imvi cyangwa imyanda irenze ibyiza kuruta imbaraga za brute. Kwiyongera kwumuringa, amabati, cyangwa chromium. Ntabwo tuvuga kwimukira nikel, ariko kubyerekeye guhindura matrix.
Twakoze ku isahani yo kwambara sisitemu yo gutwara amabuye y'agaciro. Icyuma cyera cyera cyambaraga vuba. Ibyuma byangiza byari bikomeye cyane kandi bihenze. Twatuye ku cyuma kijimye twongeyeho chromium n'umuringa. Chromium yazamuye matrike ikomeye, ya pearlitike yo kurwanya abrasion, mugihe umuringa watunganije grafite kandi ukongerera imbaraga nta buryarya bukomeye. Uwiteka kuramba hano harerekeza kuri micro-alloying kumitungo yihariye, akenshi iyobowe nimyaka yikigeragezo namakosa mubyo twanditse. Ntabwo ari byiza cyane kuruta kuvuga ko dukoresha superalloys, ariko akenshi birakora neza kandi bikoresha amafaranga menshi kubisabwa.
Aha niho uburambe bwumushinga budasimburwa. Ntushobora gukuramo gusa utuntu two mu gitabo. Biterwa n'inkomoko y'icyuma, imyitozo yawe yo gushonga, ndetse n'ingaruka z'ikirere cyaho mukumisha. Isosi y'ibanga akenshi ni imyaka mirongo gusa yamakuru yinjiye.
Kunanirwa nkumwarimu mwiza: Anecdote Yumuntu
Kera mugihe cyanjye hano muri Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), twagize ikibazo gikomeye cyahinduye uburyo bwacu. Icyiciro cya garebox yicyuma gitwikiriye ibikoresho byo mu nyanja. Batsinze cheque zose za QA. Amezi atandatu mumurimo, twabonye guhamagara ubwoba: ibice byagaragaye hafi yumwobo. Byari ibyago.
Nyuma yo gupfa. Ibikoresho byujuje ubuziranenge hamwe n amanota. Igishushanyo cyari cyiza. Nyirabayazana? Guhindura sisitemu yo guhuza umucanga kubicuruzwa bishya, byihuse. Yatezimbere igipimo cyibicuruzwa byoroheje, ariko yahinduye imbaraga zo gukonjesha bihagije mubice bikomeye bikikije abayobozi ba bolt. Yakoze zone yibirimo karbide yo hejuru gato, bituma icika. Guhangayikishwa buri gihe na moteri yinyeganyeza yasanze intege nke. Twabuze umukiriya, twishyura abasimbuye, kandi hafi yatakaje izina.
Ibyo kunanirwa byaduhatiye gushyiraho gahunda yo kugenzura impinduka. Impinduka iyo ari yo yose - binder nshya, inoculant nshya, ibikoresho bishya bya ladle liner - ubu inyura mucyiciro cyicyitegererezo no kugabana gukomeye no gusesengura mikoro. Ntabwo tugerageza gusa ibintu bisanzwe; dushakisha kuri microstructural shift ihinduka. Iri somo ribabaza ryakoze byinshi kwisi-nyayo kuramba yacu imbaraga za rukuruzi kuruta igitabo icyo ari cyo cyose. Ni inzira yavutse ku nkovu: sisitemu ya sisitemu yo kwiruka inyuma yoroheje.
Noneho, inzira zigana he? Irinde ibisubizo byoroshye. Kugana kugenzura ibikorwa byose, kuva kwigana kugeza kuvura ubushyuhe bwatoranijwe kugeza gutunganya neza. Kugana micro-alloying ishingiye kumateka yimbitse. Kandi hejuru ya byose, kubijyanye no kubahiriza ko kuramba atari umutungo ugerageza mubice; ni umuco wubaka mubikorwa. Nuburyo burambiranye, bwitondewe, butaganirwaho kugenzura impinduka ijana ntanumwe ubona-kugeza igice kiracyakora neza nyuma yimyaka. Iyo niyo nzira nyayo. Urashobora gusanga bimwe mubitekerezo byacu bikoreshwa mubikorwa byacu birambuye kurubuga rwacu kuri tsingtaocnc.com, ariko ubumenyi nyabwo, nkuko bisanzwe, buri hasi.
