Iyo abajenjeri bagaragaje imbaraga za rukuruzi yibice byicyuma-cyane cyane muri sisitemu ya hydraulic, peteroli na gaze, cyangwa inzu ya pompe iremereye - ntabwo bahitamo inzira gusa. Barimo guhitamo umufatanyabikorwa ugenzura metallurgical idahwitse, gusubiramo ibipimo, hamwe no kwizerwa kumikorere kuva kumavuta avanze kugeza igice cyarangiye. Niyo mpamvu amakipe atanga amasoko ku isi agenda yitabaza abahanga uruganda rukora rukuruzi ibikorwa-ntabwo ari ibishingwe rusange-hamwe nubushobozi bwahagaritswe, inyandiko zerekana neza, hamwe nuburambe bwagaragaye muri superalloys nka AMS 5387 na T800.
Impamvu Gravity Casting ikomeje gutsindira ubutumwa-Inganda zinganda
Gravity casting ntabwo ishaje. Byahiswemo nkana mugihe ukeneye ubucucike, buke-buke hamwe nubugenzuzi bukomeye bwimitungo-cyane cyane kubice byumuvuduko wumuvuduko ukabije cyangwa kwambara nabi. Bitandukanye n’umuvuduko ukabije wo gupfa, ibyuma bigaburirwa imbaraga zishongeshejwe byinjira mubibumbano buhoro, bigabanya imivurungano hamwe na gaze. Igisubizo? Imbaraga zingana cyane, kurwanya umunaniro mwiza, hamwe na mashini isumba izindi nyuma-byingenzi kubice nka pisitori ya pompe ya pompe ya pompe ya pisitori cyangwa imibiri ya valve yumuriro aho micro-kugabanuka cyangwa ubusa bwimbere bishobora gutera kunanirwa kumurima.
Twabonye abakiriya bahinduranya ubundi buryo bwo gushora imari nyuma yo guturika inshuro nyinshi muri cobalt-nikel ikora hejuru ya 450 ° C. Imbaraga rukuruzi zitanga ingano zikenewe zingana - kandi icy'ingenzi, zatumaga hashyirwaho neza ibyago hamwe nibiryo kugirango ibyerekezo bikomere. Urwo rwego rwo kugenzura inzira ntirubaho kubwimpanuka. Irasaba ubushishozi bwimbitse, imyaka ibarirwa muri za mirongo yerekana ibitekerezo, hamwe na ISO ikurikiza ubushyuhe bwumuriro kuri buri gusuka.
Ubushobozi bune butavuguruzwa muruganda rukora cyane rukuruzi rukuruzi
Abishoboye uruganda rukora rukuruzi igomba gutanga ibirenze gusuka ibyuma. Dore icyatandukanya abafatanyabikorwa biteguye gutanga umusaruro nabatanga ibicuruzwa:
- Ubuhanga bwibikoresho birenze amanota asanzwe: Ntabwo all cobalt alloys yitwara kimwe. AMS 5387 isubiza mu buryo butandukanye igipimo cyo gukonja kuruta T800 ishingiye. Inzobere nyayo ikomeza ubufatanye bwa tekinike hamwe nabatanga ibikoresho byemewe - kandi ikemeza buri bushyuhe burwanya ASTM E112 (ingano yingano), ASTM E353 (isesengura ryimiti), hamwe nabakiriya bagenwe umurongo uteganijwe.
- Igipimo cyimiterere murwego rwibikorwa: Byinshi mubikorwa byo hejuru bya rukuruzi bisaba CNC gutunganya nyuma. Niba inzu ya casting idafite ikigo cyayo cyo kuyitunganya - cyangwa ikabura CMMs ya GD & T-ku rubuga-ibyago byo kwihanganira cumulative kwihanganira ibintu biragwira. Twapimye kugera kuri ± 0,12 mm gutandukana muburyo bukomeye bwo guhuza bore mugihe gukina no gutunganya byagabanijwe kubacuruzi.
- Byuzuye-byuzuye bikurikirana kugeza kumashanyarazi: Kuri peteroli & gaze cyangwa hydraulic OEMs, "traceable" bivuga kumenya amafaranga yitanura ryatanze ayo gutara, ibihe byo gutunganya ubushyuhe byanyuzemo, nuwabikoraga yasinyiye ubugenzuzi bwa nyuma. Nta mpapuro. Nta cyiciro-nimero yo gukeka.
- Kwemeza imikorere - ntabwo byubahirizwa gusa: Inzu yumuvuduko wamazu irashobora gutsinda cheque ya CMM ariko iracyatemba munsi yumurongo wa 350. Uruganda rwo mu rwego rwo hejuru rukora ibizamini bya hydrostatike, igenzura ryirangi ryinjira kuri ASTM E165, ndetse na prototype-urwego rwo kugenzura-inzira mbere yo gusohora ingingo za mbere.
Niki Imishinga-Isi Yukuri Yerekana Kubijyanye no Gukura
Reba gahunda iheruka kubinyabiziga byubwubatsi kuri winch center shaft rollers. Igice cyasabye 42 HRC gukomera, kurangiza hejuru ≤Ra 0.8 µm kubinyamakuru bitwara imizigo, hamwe na zeru imbere imbere muri mm 5 zicyicaro. Uruganda rusanzwe rwavuze ibyumweru 12 rwanga uburyozwe bwo guhindura microstructure. Igisubizo cyavuye mu kigo cyakoraga umusenyi * hamwe * no kuvura ubushyuhe mu nzu, gukoresha optique yoherejwe na sprosroscopi kuri buri kintu gisuka, kandi cyemeza imyirondoro ikomeye hamwe na mape ya Rockwell B / C. Kwemeza ingingo ya mbere byatwaye iminsi 8 - ntabwo ari amezi.
Urundi rubanza rwarimo cobalt alloy plugs yo guteranya pompe yo mumazi. Uburinganire bwa geometrie bwarimo ibice bikikijwe n'inkuta (2,3 mm nominal) na radiyo y'imbere ntoya nka R0.5 mm. Ibishushanyo bisanzwe byinjira byateje ubukonje imburagihe no gufunga imbeho. Uwatanze isoko yatsindiye sisitemu ya runner akoresheje software yigana - kandi yagenzuye icyitegererezo hamwe nubushyuhe bwa temmocouple yashushanyije ubushyuhe mugihe cyo kwisuka. Ubwo buryo bwo gukora bukora gusa iyo injeniyeri ya casting yicaye hamwe na metallurgiste na programmes za CNC burimunsi.
Guhitamo Mugenzi wawe: Kurenga udutabo n'impamyabumenyi
Impamyabumenyi zifite akamaro-ariko ni ibintu byisuku, ntabwo bitandukanya. ISO 9001 ni imigabane. Niki cyimura urushinge ni gihamya yikibazo cyihariye cyo gukemura ibibazo: Ese batangaza ubushakashatsi bwakozwe kuri hydraulic valve casting umusaruro utezimbere? Bashobora gusangira amakuru yerekana amashusho kuva 10 AMS 5387 yanyuma? Raporo zabo QC zirimo amafoto ya microstructure-ntabwo ari imibare ikomeye gusa?
Reba kandi amabendera atukura: "Imwe-imwe-ihuza-byose" ibishushanyo mbonera, kutabasha gufata mm 0,05 mm kuri cast-in datum, cyangwa kwishingikiriza kumashanyarazi ya gatatu atabanje kubyemeza. Ibi bimenyetso byerekana ubushobozi - ntabwo bihujwe neza.
Kuri ba injeniyeri bashakisha imbaraga za gravit-cast uyumunsi, icyemezo ntabwo kijyanye nigiciro kuri kilo. Byerekeranye nigiciro cyuzuye cya nyirubwite: gukora bike, kwihuta kwa NPI, no kunanirwa kumurima wa zeru kubice bituma pompe ikora, kashe ya valve, hamwe nibinyabiziga bikora mubidukikije bikabije. Ukwo kwizerwa gutangirira kuri a uruganda rukora rukuruzi ifata buri gusuka nkubushakashatsi bugenzurwa-na buri mukiriya ashushanya nkibisobanuro bikora.
