Iyo abantu benshi bumvise 'ibice byimashini,' bashushanya igishushanyo cya CAD cyangwa ikintu kibengerana muri kataloge. Iyo ni verisiyo isukuye. Ukuri, kugukomeza nijoro, ni ibijyanye no kuva muri ubwo buryo bwiza bwa digitale ukajya mubice bifatika bikora munsi yumutwaro, ubushyuhe, hamwe na stress. Ikinyuranyo hagati yo gushushanya nibintu bikora niho inganda nyazo zituye-kandi aho amafaranga menshi yatakaye kubitekerezo.
Ibishushanyo byo Guhinduranya
Kimwe mu bitekerezo bitari byo ni uko igice ari urwego gusa. Urashobora kugira bibiri ibice by'imashini uhereye kubatanga ibintu bitandukanye bapima kimwe kuri CMM, nyamara umwe ananirwa mubyumweru undi amara imyaka. Itandukaniro ntabwo riri muri geometrie; ni mubitaka byimbuto zo guhimba, umurongo wo kuvura ubushyuhe, cyangwa guhangayikishwa no gutunganywa. Nabonye icyiciro cya pompe ya pompe cyanyuze kuri buri gipimo gipima ariko gifata kubera ko ibikoresho byabigenewe - ibyuma byari bikomeye. Icapiro ntabwo ryerekanye inzira ya metallurgiki, gusa ubukana bwa nyuma. Iri ryari isomo rya $ 200k.
Aha niho hashingiwe gushinga no gutunganya ibintu biba bidashoboka. Ntushobora gutanga isoko gusa kubapiganwa bahendutse hamwe na mashini ya CNC. Inzira ni igice cyibicuruzwa. Kurugero, kuri Ikoranabuhanga rya Qingdao Qiangsenyuan (QSY), hamwe nimyaka mirongo itatu mugukora no gutunganya, bakubwira ko igishishwa cyibishishwa kumubiri wa valve kizaba gifite uburinganire bwubuso butandukanye kandi hafi ya net ugereranije no guta umucanga, ndetse no murwego rumwe rwibyuma bitagira umwanda. Ibyo bigira ingaruka kuburyo utegura intambwe zawe za CNC zikurikira - inzira zawe, inzira zawe. Niba uyikoresheje nka billet, urimo kumenyekanisha guhangayikishwa bamaranye imyaka 30 biga kwirinda.
Iraguhatira gutekereza inyuma. Utangira nuburyo bwo gutsindwa. Ni umunaniro? Kwambara? Ruswa? Noneho urasubira inyuma kubintu nibikorwa byo gukora. Igice cyumurongo wo gutunganya ibiryo gikozwe muri 316L kitagira umwanda ntabwo kijyanye no kurwanya ruswa gusa; ni bijyanye nuburyo ibice by'imashini Byarangiye. Indorerwamo yindorerwamo irashobora kugaragara neza, ariko irema micro-crevices ibika bagiteri? Rimwe na rimwe, kugenzurwa, guhuzagurika kuva muburyo bwihariye bwo gutunganya ni byiza. Urupapuro rwihariye ntirukubwira ibyo.
Ibikoresho ni inzira, ntabwo ari uguhitamo
Gutoranya ibyuma bitagira umwanda cyangwa nikel-ishingiye kuri alloy kuva menu yamanutse ni intangiriro yikiganiro, ntabwo iherezo. Fata Inconel 718. Ibintu byiza. Ariko uko iterwa nuburyo yahimbwe ikora microstructures zitandukanye. Niba urimo kuyitunganya, itandukaniro mubukomere no gukomera kumurimo bizasenya ibikoresho byawe niba ukoresheje ibipimo bimwe. Ibikorwa bya QSY hamwe nuruvange rwihariye birerekana ibi-bagomba guhindura inzira zabo zose bakurikije niba ibicuruzwa byinjira biva mubushoramari cyangwa mu kabari. Ubuvuzi bwa post-casting bwo kugabanya ibibazo ni ngombwa; gusimbuka, kandi igice kizarigita mugihe cyo gutunganya bwa nyuma, uhindure igice cyuzuye mubisigazwa.
Ndibuka umushinga wimpeta ya turbine. Igishushanyo cyahamagariye kobalt ishingiye kuri cobalt, Stellite 6, igenewe kwihanganira kwambara cyane. Twashakishije verisiyo yabakinnyi. Yakoze cyane - kuganira, kwambara ibikoresho byari inyenyeri. Ikibazo? Igikorwa cyo gukina cyaremye karbide nini, matrike yoroheje. Igisubizo, twahageze nyuma yikigeragezo kibabaje namakosa, kwari uguhindura ifu ya metallurgie ya verisiyo imwe, yatangaga karbide nziza kandi nziza. Yakoze isuku kandi ikora neza. Isomo: izina rya alloy ni resept gusa; uburyo bwo gukora nubuhanga bwo guteka. Urashobora kwangiza resept nziza hamwe nubuhanga bubi.
Iyi niyo mpamvu gufatanya nuwabitanze agenzura casting na Imashini ya CNC munsi y'inzu imwe ntabwo ari ibintu byiza; ni ingamba zo kugabanya ingaruka. Iyo umukanishi ashobora gusubira kumuyobozi wumushinga akavuga ati, Iki cyiciro ni gummy, ibikoresho birapakurura, birashobora kugisubira inyuma kubushyuhe cyangwa igipimo cyo gukonja. Ibyo bitekerezo bisubirwamo ntibigaragara mubucuruzi bwubucuruzi bwuzuye cyangwa iduka rikora imashini gusa. Ku kigo nka QSY, uko kwishyira hamwe nibicuruzwa.
Ubworoherane: Igiciro cyo Gutungana
Umuntu wese arashaka kwihanganira byimazeyo. Irumva ari nziza. Ariko kwerekana ± 0.01mm kwihanganira kuri buri gipimo cya casting igoye ninzira nziza yo kwikuba inshuro eshatu no gutinza umushinga. Ugomba kumva icyo kwihanganira bigamije. Birakwiriye? Kubikorwa? Kuringaniza? Akenshi, intera imwe cyangwa ebyiri zingenzi zikenera ubwo busobanuro. Ibisigaye birashobora kuba byoroshye. Njye namaze amasaha hamwe naba injeniyeri mpaka kwihanganira hejuru yimikorere idakorwa, nkiza ibyumweru byigihe cyo gukora nigiciro cyibikoresho.
Ikibazo nyacyo ni ugucunga uburyo bwo kwihanganira uburyo butandukanye bwo gukora. Urashobora kuba ufite inzu ikozwemo icyuma gikonjesha Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nicyuma kidafite ingese kanda-yashyizwemo. Kugabanuka kwa casting, gutunganya datum, coefficient zo kwagura ubushyuhe-byose bigomba kwiganwa. Twigeze kugira icyiciro cy'inteko zafashe ubushyuhe bwo gukora. Kucyumba cyicyumba, imashini ikwiye yari itunganye. Ariko ntitwashoboye kubara igipimo cyubwiyongere butandukanye bwubushyuhe bwicyuma cyuma nicyuma. Gukosora ntibyari byoroshye gutunganya; byari bitandukanye kubara ukurikije ubushyuhe bwa serivisi. Igishushanyo cyari gikwiye kuri 20 ° C, ariko imashini ntiyakoraga kuri 20 ° C.
Aha niho uburambe bwimyaka irenga 30 butari umurongo wo kwamamaza. Nibitabo byibikorwa byubushyuhe nubukanishi. Iduka rishya rishobora gutera imisumari icyumba-ubushyuhe kandi rigatanga igice cyananiranye. Umuntu w'inararibonye azabaza ati, Ibi bizakoreshwa he? Ubushyuhe bwibidukikije ni ubuhe? Nibizunguruka bikabije? mbere yuko bategura na CNC.
Kunanirwa nkuwatanzwe
Wiga byinshi mubice byacitse kuruta kubikora. Ikizamini cyangiza ntabwo ari R&D gusa; bigomba kuba bimwe mubikorwa byujuje ibyangombwa byingenzi. Twashyizeho politiki yo guhangayika cyane ibice by'imashini: kugenzura ingingo ya mbere harimo gukata imwe. Reba neza imbere muri casting, bapime uburebure bwikibazo cyo kuvura ubushyuhe, reba ubusa cyangwa ibirimo. Birahenze, ariko bihendutse kuruta kwibutsa umurima.
Urubanza rwihariye rwarimo uduce tumwe na tumwe twa feri ya convoyeur iremereye. Batsinze ubugenzuzi bwose no gupima imitwaro. Ariko mugihe cyo gutemagura, twasanze kugabanuka kwikuramo nka 2mm munsi yubuso ahantu hahangayitse cyane. Munsi yo gupakira cyclic, ibyo byaba ari umunaniro ucitse nucleation point. Uruganda, muriki gihe, rwahinduye igishushanyo cyarwo na riser kuri icyo gice cya geometrie. Gukosora byari mubibumbano, ntabwo byari imashini. Niba ugenzuye gusa imashini yanyuma, wabuze inkuru ibera munsi.
Guhindura imitekerereze - kuva kugenzura iyubahirizwa kugeza kugenzura kubyumva - ni ngombwa. Ihindura ishami rishinzwe kugenzura ubuziranenge kuva kumurinzi uhinduka isoko yubwenge. Yubaka kandi umubano utandukanye nuwabitanze. Mugihe ushobora kugirana ikiganiro cya tekiniki kubijyanye na selile ya eutectic kubara mubyuma cyangwa sigma icyiciro cya sigma mugice cyo gusudira kidafite ingese, wimuka uva mubiguzi ujya mubufatanye. Abatanga ibintu nkibyo inyuma tsingtaocnc.com fata ukundi iyo babonye ureba ibibazo bimwe byingenzi.
Ibyiza bihagije
Hanyuma, ubwenge bwatsinzwe cyane: ntabwo buri gice gikeneye kuba igihangano. Gukurikirana gutungana birashobora kuba umwanzi wimikorere ninyungu. Hano hari inzira nziza ihagije yasobanuwe na porogaramu. Agace kifata igifuniko kidakomeye ntigikeneye ikirere cyo mu kirere cyo mu kirere hamwe na anodizing. Isahani ishyushye isahani, gukata laser no guteshwa agaciro, izakora akazi kuri 1/10 cyigiciro. Ubuhanga ni mukumenya neza urwo rugabano.
Aha niho uburambe bwagutse mubikoresho nibikorwa bitanga umusaruro. Kumenya ko kubidukikije bimwe byangirika, byakozwe neza neza ibishishwa bikozwe muburyo busanzwe bwa CF8M bitagira umuyonga bishobora gukora kimwe na super duplex ihenze cyane, niba igishushanyo ari cyiza. Cyangwa ngo kubwubuso bwambarwa, rimwe na rimwe wongeyeho ibintu byoroshye, bisimbuzwa ibyuma byinjizwamo ibyuma birusha ubwenge kuruta gukora igice cyose cya monolithic kivuye mumashanyarazi ahenze. Nibijyanye no gushushanya sisitemu, ntabwo ari ibice gusa.
Amaherezo, ibice by'imashini ni kwigaragaza kumubiri ibyemezo igihumbi - ibintu, inzira, kwihanganira, kurangiza, kugenzura. Igishushanyo mbonera ni intangiriro yo kwongorera. Gutontoma biva mu ruganda no mu iduka ryimashini, aho uburambe, akenshi bwigishijwe no kunanirwa kwashize, bihindura ibisobanuro mubintu bikora gusa. Ntabwo ari bike kubijyanye nigishushanyo cyiza cyumuntu kugiti cye nibindi byinshi byerekeranye nigikorwa gikomeye, gisubirwamo murwego rwimikorere ihuza. Nibyo ugura rwose.
