Imbaraga rukuruzi zihoraho zishiraho ibisubizo bisaba ibirenze ibyuma bishongeshejwe nicyuma. Bakenera kugenzura neza ubushyuhe, gucunga ubuzima busubirwamo, hamwe na disipulini ya metallurgjiya - cyane cyane iyo itanga ibice byuzuye byubuvanganzo bwa pompe hydraulic, indiba za peteroli, cyangwa sisitemu yimodoka. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashyize ibice birenga 12.000 byapimwe nicyuma cyuma nicyuma mubibumbano bihoraho kuva 2018 - kandi gutsindwa kwose, buri kantu kose kagenda gahindagurika, buri kintu cyose cyagabanutse mikorobe yatwigishije ikintu kimwe: guta uburemere ntabwo ari ugusuka gusa. Igenzurwa no gukomera.
Ni ukubera iki Kuringaniza Ibihe Byose Bikomeza Gutsindira Ibice Byinganda Hagati
Ba injeniyeri bamwe batekereza ko gushora imari bisimbuza imbaraga zihoraho. Ariko mubikorwa nyabyo-ntabwo ari laboratoire - ibumba rihoraho ritanga uburyo bukomeye bwo gusubiramo amazu nka pisitori ya pisitori ya pisitori hamwe numubiri wa valve. Kubera iki? Kuberako ubushyuhe bwibumba buguma muri ± 5 ° C mugihe cyizuba 300+ mugihe ukoresheje ibyuma bishyushye, bisize H13 ibikoresho byuma. Gutera umucanga ntibishobora guhura nuwo mutekano. Gushora imari bizana ceramic shell variable hamwe nibibazo byinshi bisigaye. Turabipima: kuri mm 420 mm × 280 mm × 120 mm ya pompe ya pompe, ibumba rihoraho rifite kwihanganira imyanya ya GD&T kugeza kuri mm 0.15 hejuru ya 500; impuzandengo yumucanga impuzandengo ya mm 0.32 mm, hamwe na 17% byashaje kubera ihinduka ryibanze.
Dukoresha imbaraga ebyiri zidasanzwe za rukuruzi zihoraho - imwe kumyuma ihindagurika (ASTM A), imwe kumashanyarazi make (A105N). Byombi ukoreshe hasi-gusuka amarembo, gushiramo gushiramo ibice bikomeye, hamwe nigihe gikurikiranwa cya thermocouple kurukuta rwububiko. Nta gukeka. Nta gihe "cyisanzwe" cyigihe. Buri gice gifite umwirondoro wacyo ushushanyije muri raporo yacu yo kwemeza.
Aho Inganda nyinshi Zananiwe-nuburyo Twabikosora
Imirasire myinshi ihoraho yibikorwa byuruganda isenyuka kubintu bitatu: kwangirika kwibumba, ubushyuhe budahuye, hamwe nubushakashatsi budahagije bwo kugaburira ibiryo byihariye. Twabibonye ubwacu kuri AMS 5387 cobalt alloy pump gahunda yo guturamo. Abakinnyi 19 ba mbere berekanye ububobere buke munsi ya flange - nubwo chimie itunganye. Impamvu? Ubuso bwa okiside nyuma yuburyo 42 bwahinduye igipimo cyo gukuramo ubushyuhe. Igisubizo: ubu twongeye kwibutsa buri shusho 35 dukoresheje guturika kwa alumina hamwe na borosilicate ya nyirubwite - byagenzuwe na test ya emissivité ya infragre mbere yo gusuka.
Turashimangira kandi indero ikaze. Ibishusho byacu ntabwo byigera byinjira mu ziko. Binyunyuza kuri 280 ° C muminota 90, hanyuma bakazamuka kuri 320 ° C ± 3 ° C hanyuma bagafata iminota 45 - bipimirwa ahantu h'ubujyakuzimu. Ibyo ntibishobora kuganirwaho. Simbuka, hanyuma ubone gukonjesha cyangwa gukora nabi mubice bya T800. Abakiriya batanga imiterere yabo akenshi birengagiza ibi. Turagerageza ibyabo mbere yo kwemerwa.
Kwishyira hamwe ninyungu nyayo-Ntabwo ari ugukina gusa
Imirasire yukuri ihoraho mold casting uruganda igisubizo ntigihagarara kuri shakeout. Irakomeza binyuze mumashini, kuvura ubushyuhe, na metrologiya - byose munsi yinzu. Ku kigo cyacu cya Qingdao, inzu ya silinderi yimuka yimuka ikavaho ikava kuri CNC ikingura Mazak Integrex i-200S. Nta gutinda kwa logistique. Nta gukemura ibyangiritse. Nta guhuza sisitemu gusubiramo. Dukora imashini zikomeye mugihe casting ikiri muri 50 ° C yubushyuhe bukomeye - kugabanya kugoreka 40% ugereranije no gutunganya ubushyuhe bwicyumba.
Guhuza kwacu guhagaritse gukubiyemo ibice bine: ibyemezo byibikoresho (ubushyuhe bwose bushobora gukurikiranwa na raporo yikizamini cyurusyo), kwemeza inzira yo gutoranya (hamwe na radiografiya na ultrasonic sampling kuri ASME B16.34), gutunganya neza (CMM yagenzuwe na ISO 2768-mK), hamwe no gupima imikorere (ibizamini bya hydrostatike bigera kuri 450 kubikoresho byubatswe). Niyo mpamvu imashini yacu ya winch ya shitingi yimodoka zitari mumihanda igera ku 100% yumusaruro wambere-ndetse hamwe na kaseri zidasanzwe hamwe nubuso bwahagaritswe.
Guhitamo Mugenzi wawe Ntabwo bijyanye nigiciro-Byerekeranye no guhanura
Niba umushinga wawe ukeneye imbaraga za rukuruzi zihoraho zogutwara igihe, zifata GD&T nta mpaka, hamwe nibimenyetso byerekana ibicuruzwa mbere yuko ibikoresho bitangira - ukeneye ubushobozi bwanditse, ntabwo bisaba ibicuruzwa. Baza ibi bibazo bitatu mbere yo gusinya:
- Urashobora kunyereka paki yawe ya nyuma ya PPAP-harimo ibiti byo kubungabunga ibishushanyo mbonera hamwe n'ubushyuhe bwa cavity?
- Ukora isesengura-ryerekana isesengura kuri buri bushyuhe, cyangwa gusa ku ngingo ya mbere?
- Iyo casting yananiwe NDT, utanga raporo y'ibikorwa ikosora-cyangwa wongeye gusubiramo?
Twese uko ari batatu. Igihe cyose. Sisitemu yacu ISO 9001: 2015 ikurikirana buri shusho, buri kintu kibisi, buri ngingo ya CMM. Nta na kimwe kidasanzwe. Nuburyo dushyigikira abakiriya muri Amerika ya ruguru, Ubudage, na Singapuru-hamwe na zero zitinze gutangwa ku bicuruzwa bito bito mu 2023.
Urebye imbere, turimo kwagura imbaraga zacu zihoraho zububiko bwinganda zikora mubikorwa bivangavanze: hafi-net-shusho-ya-ishusho ihoraho ibumba irangiye hamwe na CNC ifashwa na laser yo gusya cobalt-nikel. Ntabwo ari ukubera ko ari agashya-ariko kuberako amakuru yumurima yerekana ko agabanya igiciro cyose 22% kubice bisaba geometrike igoye ndetse no kwihanganira kwambara cyane. Icyitonderwa ntabwo ari ishami. Ni urukurikirane.
