Iyo ba injeniyeri bagaragaje Nickel 400 alloy part uruganda inkunga, ntabwo batumiza ibyuma gusa-barasaba ituze ryikigereranyo munsi yumukino wo gusiganwa ku maguru, kurwanya ruswa mumazi ya hydraulic yuzuye chloride, hamwe nubuzima bwumunaniro uhuye n ibahasha ya serivise yinteko za pompe zo hanze. Twabonye imishinga myinshi ihagaze kuri prototype kuberako abatanga isoko bafataga Nickel 400 nkicyuma gisanzwe kitagira umwanda: inzira imwe, inzira imwe ikonje, kwihanganira ubugenzuzi. Ntabwo bikora. Nickel 400 ya 63% ya nikel, ubushyuhe buke bwumuriro, hamwe nugukomera kumurimo bisaba indero itandukanye - imwe yashinze imizi mubyuma bya metallurgjiya, ntabwo ari ubushobozi bwo gukora gusa.
Impamvu Nickel 400 yananiwe-Kandi aho inganda nyazo zigenda neza
Kunanirwa kwinshi bikurikirana amakosa atatu yakwirindwa. Icya mbere: gushakisha ibikoresho. Nickel 400 ntishobora guhinduranya ubushyuhe. ASTM B164 isaba kugenzura cyane karubone (<0.3%), sulfure (<0.024%), n'icyuma (1.5-2,5%). Twigeze kwakira icyiciro hamwe na karuboni 0.42% - mubipimo byuruganda ariko birahagije kugirango habeho gucikamo ibice hagati yigihe cyo kugabanya imihangayiko. Icya kabiri: ingamba zo gutunganya. Ibikoresho bisanzwe byihuta byihuta gucukura; karbide yambara vuba; ubushyuhe bwubaka aho butagomba. Amaduka atsinze akoresha uburyo bukomeye, igipimo gito cya RPM / kugaburira ibiryo byinshi, hamwe no gukonjesha kwa kirogenike - ntabwo ari umuvuduko, ahubwo ni uguhagarika imirimo ikomera mbere yuko ifunga kugoreka microstructural. Icya gatatu: gutunganya nyuma yimashini. Nickel 400 yunvikana kumaganya asigaye. Ibice byakorewe nta nzitizi zigabanya ubukana akenshi biraterana mugihe cyo guterana kwa nyuma cyangwa kunanirwa kwipimisha hydrostatike kuri 1.5 pressure igitutu cyakazi.
Ubushobozi bune budasubirwaho kubikorwa byizewe Nickel 400
Nukuri Nickel 400 alloy part uruganda igomba gutanga ibirenze kwihanganira igishushanyo. Igomba gutunga urunigi rwuzuye:
- Kugenzura ibisekuru.
- Igikoresho cyihariye: Impamyabumenyi ya karbide yihariye hamwe na TiAlN yatwikiriye, gushyiramo-ubutaka kugirango ugabanye guhagarikwa kumibiri ya valve, hamwe nibikoresho byinyeganyeza byubatswe kumazu ya silinderi yoroheje.
- Guhuza imicungire yubushyuhe.
- Kwemeza imikorere birenze CMM: Kwipimisha igitutu kugera kuri 700, kugenzura helium kumeneka hejuru yikimenyetso, hamwe no kugenzura ububi bwubuso kumuhanda utemba ukoresheje profilometero - ntabwo ari optique gusa.
Ibi twabyemeje mugihe cyateganijwe giheruka kububiko bwa pisitori ya piston pompe ikoreshwa muri sisitemu ya hydraulic yo mumazi. Umukiriya yasabye Ra ≤ 0.4 µm hejuru yimbere yimbere hamwe na zeru zeru mugice cya mm 2 cyurukuta rwegeranye nicyambu. Gutera umucanga bisanzwe ntibishobora kwemeza ubucucike. Gushora imari byatanze ubunyangamugayo-ariko nyuma yuko duhinduye igishashara cyo kugabanya ibishashara kuri + 0,12% kugirango duhangane na Nickel 400 idasanzwe yo gukomera. Ihindurwa ryaturutse kuri 17 yabanje kubaka, ntabwo ari urupapuro.
Ibyo abakiriya babaza mubyukuri - mbere yo kuvuga
Amakipe atanga amasoko ntabwo ayoboye hamwe na "Ufite ISO 9001?" Babaza ibibazo bikaze:
- “Urashobora gufata mm 0,015 mm kuri mm 300 z'uburebure, nyuma yo kugabanuka?”
- "Ni ikihe gipimo cyawe cyo kwangwa ku bice bisaba> gukuramo ibikoresho 50%?"
- "Nigute ushobora kugenzura uburinganire bwa microstructure hejuru ya kg 45?"
- "Niba GD&T yacu isaba kwihanganira imyanya itatu ku mwobo wa bolt ugereranije n'indege ya datum, ni ubuhe buryo bwawe bwa mbere bwo kugenzura?"
Igisubizo ntabwo "Dukoresha CMM." Ni "Dushira igice kubantu ba kinematike, dusuzume indege ya datum hamwe na laser tracker, hanyuma dusuzume ibintu byose muburyo bumwe - nta guhinduranya, nta kosa ryo guhuriza hamwe." Urwo rwego rwo gutunga rutandukanya inganda n'amaduka y'akazi.
Kureba imbere: Aho Precision ihura nibiteganijwe
Imipaka ikurikira ntabwo yihanganira gusa-ni uguhuzagurika. Ubu turimo gushira ubushyuhe bwigihe-nyacyo muri CNC izunguruka mugihe cya Nickel 400 itoroshye. Iyo spindle temp yazamutse hejuru ya 38 ° C, sisitemu ihita igabanya ibiryo 12% kandi bigatera kugenzura gukonjesha. Ntabwo ari ukurinda kumeneka ibikoresho-ahubwo ni ugukomeza igihangano muri 2 ° C yumuriro wumuriro wose. Kubera iki? Kuberako Nickel 400 ya moderi ya elastike ihinduka kuburyo bugaragara hagati ya 20 ° C na 45 ° C. Ihinduka rihindura gutandukana munsi yingufu zifatika - no gutandukana bihindura uruziga rwanyuma.
Nibyo byukuri inyuma ya buri kwizerwa Nickel 400 alloy part uruganda: ifata metallurgie nkintambwe yambere yintambwe, ntabwo isanduku yanyuma yo kugenzura. Irabizi ko gutandukana kwa mm 0.005 ntabwo ari ugupima-ni ukumenya niba igice cyarokotse umuvuduko wacyo wa gatatu mu nyanja y'Amajyaruguru. Niba ibikurikira bya Nickel 400 bigomba gukora - ntabwo byatsinze igenzura gusa - uruganda wahisemo rugomba kuvuga ururimi rwa atome, ntabwo ari inguni gusa.
