Iyo ba injeniyeri bagaragaje a uruganda rwicara, ntabwo batumiza igice gusa-barinda umutekano muke munsi yumurongo wa 350, kwambara birwanya nyuma yizunguruka 10,000, hamwe no guhuza metallurgjique mubice 500. Twabonye imishinga myinshi ihagaze kubera ko intebe yatambutse mugihe cyamagare yubushyuhe, cyangwa micro-porosity yatumaga hakiri kare muri hydraulic manifolds. Niyo mpamvu ubusobanuro butari bwo kwamamaza-nibisabwa byibuze byinjira.
Kuki "Valve Seat Uruganda" Nijambo Rishakisha Ryayobya-Kandi Ukeneye Mubyukuri
Abaguzi benshi bandika "uruganda rukora valve" muri Google bategereje umusaruro wa turnkey. Ariko mubikorwa, intsinzi ishingiye kubushobozi butatu butavugwaho rumwe: ubuhanga bwibintu, ubudahemuka bwa geometrike, hamwe nuburyo bukurikirana. Umufatanyabikorwa nyawe agomba gukoresha AMS 5387 ya cobalt ivanze - ntabwo ari imashini gusa, ahubwo akayijugunya hamwe na dendritic spaced, hanyuma akarangiza-agashyira kashe kuri ± 0.005 mm TIR mugihe arinze guhagarika umutima. Twatanze intebe zirenga 12,000 za pompe ya piston yumuvuduko mwinshi kuva 2019. Buri cyiciro gitwara ubushyuhe bwuzuye, CMM itanga raporo ya diametre zikomeye, hamwe no kugenzura ububi bwa Ra ≤ 0.4 µm kumaso.
Ibintu bine bya tekinike Abatanga isoko benshi ntibazatangaza
Ubwa mbere, cobalt-nikel alloys isaba guhuza ibikorwa-gutunganya akazi. Intebe zumucanga akenshi zisaba gukuramo 40% byimigabane-cyane kubikoresho bisanzwe. Twifashishije karbide yihariye hamwe na PVD TiAlN hamwe nigipimo cyibiryo byoguhindura bigabanuka kuva kuri mm 120 / min kugeza kuri 35 mm / min mugihe twambutse akarere katewe nubushyuhe hafi yicyicaro.
Icya kabiri, gusobanura GD&T bigira ingaruka kumikorere. Icyicaro cyerekanwe na Ø0.015 mm kwihanganira imyanya ugereranije na pilote? Ibyo bisaba guhuza-optique ihuza-ntabwo igenzurwa nyuma yo kurangiza. Tugenzura imibare ya datum mbere yo kuvura ubushyuhe bwa nyuma, ntabwo nyuma.
Icya gatatu, ubusugire bwubuso butsinda ubukana bwonyine. Dupima mikorobe ikomeretsa hejuru yintebe (HV300 - HV420) kandi tugakora ibizamini bya fluorescent yinjira mubufindo bwose - ntabwo ari ingero gusa - kugirango dufate imivurungano yo munsi y'ubutaka itagaragara kuri CMM.
Icya kane, ibyemezo bifatika ntacyo bivuze nta bufatanye bwabatanga. Dufatanya guteza imbere bilet mbisi hamwe nu mutanga wa cobalt alloy utanga mubudage, dutegeka raporo yubunini bwa ASTM E112 no kugenzura kurwanya ruswa hagati ya ASTM G28A.
Niki Gushiraho Icyicaro Cyuzuye Cyicaro Cyakozwe
Ntabwo ari ugutunga imashini za CNC. Nijyanye no kugenzura ibiba hagati yabo:
- Kugenzura.
- Gukoresha indero.
- Kwishyira hamwe.
- Kurangiza kwemeza: Ubuso bwa topografiya yerekana ikarita ikoresheje interfeometrie yera-ntabwo ari inzira ya profilometero gusa - kugirango yemeze igipimo cy’ahantu (Abbott curve) cyujuje ibyapa bya hydraulic
Twanze 6.2% ya cobalt alloy fagitire yinjira dushingiye kuri ultrasonic yonyine. Ibyo ntabwo ari uguta-ibyo birinda kunanirwa mu murima.
Guhitamo Intebe Yawe Yumufatanyabikorwa: Kugenzura Bitatu
Mbere yo gusinya NDA, saba ibi - hanyuma urebe:
- Saba raporo eshatu za nyuma za CMM kumwanya umwe wa geometrie. Gereranya nukuri na nominal kumaso yikimenyetso, diameter yindege, hamwe na perpendicularity. Niba basangiye gusa incamake yamakuru, genda.
- Baza raporo y'ibizamini byabo (MTR) imiterere. Gukurikiranwa kwukuri bisobanura buri bushyuhe buhuza isesengura ryimiti, ibisubizo bikaze, namafoto ya microstructure - ntabwo ari numero yicyemezo gusa.
- Ongera usubiremo ubushobozi bwabo bwa GD&T. Bemeza kwihanganira imyanya ihuriweho? Bashobora gufata umwirondoro wubuso muri mm 0.008 mm hejuru ya 120 ° arc? Niba igisubizo cyabo kirimo "tuzagerageza," ntabwo babikoze mbere.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora muri ubu buryo buri munsi - ntabwo ari ibintu bidasanzwe, ariko nk'uburyo busanzwe. Ikigo cyabo cyujuje ISO muri Qingdao gikora ibintu byose kuva AMS 5387 cobalt alloy nozzles kugeza kumfatiro zicyuma zidafite ingese, hamwe nibyangombwa byose bivuye mubikoresho byakuwe mubizamini byanyuma.
Igitekerezo cya nyuma: Igipimo gipimwa mukwirinda kunanirwa
Intebe ya valve isohoka mu kabari 200 ntabwo igura amadorari 87 yo gusiba. Igura amadorari 12,000 mugihe cyo kumanura uruganda rwo gucukura. Igura amadolari 220.000 yo gusaba garanti yimodoka yimodoka. Bisaba icyubahiro-mugihe umukiriya wawe-umukoresha wa nyuma ashinja * ikirango cyawe kunanirwa.
Uburenganzira uruganda rwicara ikuraho izo variable mbere yuko chip yambere iguruka. Ntabwo bahuye gusa na spes-barateganya uburyo kwaguka k'ubushyuhe, inyundo y'amazi, hamwe no gupakira cycle bizakorana na geometrie na microstructure. Ibyo ntabwo ari ugukora. Nibyo kwimura ibyago-byakozwe neza.
