Iyo injeniyeri zikeneye a uruganda rwo guta ibishashara itanga ibisobanuro bisubirwamo kuri cobalt alloy nozzles, amazu ya pompe ya AMS 5387, cyangwa shitingi ya T800 - ntabwo bohereza ibishushanyo gusa. Baragerageza gutanga ibikoresho bya metallurgjique, kugenzura ibipimo, nubushake bwo kwerekana amakimbirane ya GD&T mbere yuko ibikoresho bitangira.
Twabonye ibintu bitatu byananiranye mubufatanye bwishoramari risobanutse neza: icya mbere, imiterere yingano idahuye murwego rwubushyuhe bwa cobalt-nikel; icya kabiri, ibipimo byagenzuwe na CMM byatsinze igenzura ariko bikananirana kwipimisha imikorere kubera guhangayika; icya gatatu, ubuso burangiza ibintu byahuye kumpapuro - ariko micro-porosity itesha agaciro ruswa muri serivisi ya peteroli na gaze. Ntabwo ari amakosa yo gukora. Nibyuho bitunganijwe.
Impamvu Kwishyira hamwe Bifite akamaro Kurenza Icyemezo wenyine
Icyemezo kikugeza kumuryango. Kugenzura ibikoresho bikurikirana bikomeza gukora mubikorwa. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri casting ya AMS 5387 itangirana na fagitire yemewe ya T800 yumusemburo - igenzurwa na chimique imaze kwakirwa, igatandukanywa numubare wubushyuhe, ikanakurikiranwa no gusesengura gushonga, kubaka ibishishwa, ibishashara, gutwika, gusuka, no kuvura ubushyuhe nyuma yubushyuhe. Nta cyiciro cyimuka kidafite optique yoherejwe na sprosroscopi (OES) hamwe namateka yubushyuhe.
Ibi ntabwo ari ugukurikiza amahame. Muri gahunda imwe iheruka yo muri Amerika ya ruguru kububiko bwa pisitori ya piston pompe, itsinda ryacu ryafashe 0,012% ya karuboni mu bubiko bwatanzwe na cobalt alloy stock yatanzwe mugihe cyo kugenzura. Twahagaritse gukina, dushakisha izindi fagitire, hanyuma twongera gukora simulation yumuriro - twirinda ibyumweru 14. Ibyo ntabwo ari kugabanya ingaruka. Ibyo byashizwemo na metallurgical accountability.
Ubushobozi buhagaze bivuze gukora imashini ntabwo ari ugutekereza. Cobalt alloy nozzle ntabwo iterwa noneho "yoherejwe muri CNC." Yashyizwe hamwe na 0.3 mm yo gutunganya imashini, ikozwe nabi mugihe ikiri ishyushye kugirango igabanye imihangayiko, ishaje, irangije-gutunganyirizwa kuri 5-axis DMG MORI ya moteri ikoreshwa na progaramu ya progaramu-kandi igenzurwa ikoresheje Zeiss CONTURA G2 CMMs ihinduranya buri munsi na ba shebuja ba NIST. Ihame ryimiterere ntiripimwa kugenzura ryanyuma. Yashizwe mubikorwa.
Aho Uruganda rusanzwe rushyira imipaka - nuburyo abafatanyabikorwa ba Precision bitabira
Bamwe bashobora kuvuga ko guta umucanga bihagije kubice byibyuma biremereye nkibishingwe bya pompe. Ariko iyo uburebure bwurukuta butandukanye kuva kuri mm 25 kugeza kuri mm 120 muri casting imwe - kandi ubunyangamugayo bukora busaba ≤0.05 mm uburebure bwa mm 600 - ibishishwa byerekana neza ntibishobora kuganirwaho. Gutaka ibishashara byatakaye ntabwo "byiza." Nuburyo bwonyine bugenzura gukomera gahoro gahoro bihagije kugirango wirinde kugabanuka hagati yibice byimbitse mugihe ufashe ± 0,15 mm kwihanganira kuri flanges.
Mubisanzwe tubona abakiriya bahinduye umusenyi bajya gushora imari hagati yumushinga - ntabwo ari ubwiza, ahubwo kubera ko imibiri yabo ya hydraulic valve yagumye inanirwa kwipimisha kuri 4200 psi. Impamvu? Micro-shrinkage porosity kumurongo wo gukonjesha imbere. Guhindura ibishashara byazimiye hamwe no kugenzura no kugenzura icyerekezo byakuyeho inenge. Uburemere bw'igice bwiyongereyeho 3,7%. Igipimo cyo gutsindwa kumurima cyamanutse kiva kuri 12% kigera kuri zeru.
Ihinduka ryasabye ibirenze ibikoresho. Byasabye abajenjeri ba casting bavuga GD&T neza, abakanishi bumva uburyo igipimo cya cobalt cyogukora akazi kigira ingaruka kumurongo ukurikirana, hamwe nabatekinisiye ba QA batojwe guhuza ibisubizo bya ultrasonic scan hamwe nibibari byipimishije byasutswe kumurongo umwe.
Ibisohoka-Byisi-Ibisohoka: Mbega Ikintu Cyukuri Cyatakaye Uruganda rutanga
Ni ubuhe busobanuro busobanura hasi mu iduka? Ibisubizo bine bifatika:
- Imikorere ya geometrie, ntabwo ibipimo byizina gusa-Umuvuduko wimyubakire yimyubakire yakozwe kugirango icapwe, ariko kandi yemerewe guhuza inzira-inzira ihuza kwaguka kwinshi
- Batch-to-batch metallurgical guhuza—AMS 5387 ibice byageragejwe kuri ASTM E112 kubunini bwingano, ASTM E140 kubukomere, na ASTM E8 kubwimbaraga zingana - byose byanditse kuri numero yubushyuhe
- Ubuso bwubuso bwahujwe no gusaba—Ra 0.4 µm kumaso yo gufunga, Ra 3.2 µm hejuru yubuso, hamwe nibisasu byatewe no guhagarika ibisigazwa byibisigisigi kuri zone yumunaniro mwinshi.
- Zeru zitunguranye kuri Ingingo ya mbere Kugenzura—Ibikoresho byuzuye bya FAI birimo ibikoresho bifatika, ibiti bivura ubushyuhe, raporo ya CMM, amakuru yo kurangiza hejuru, hamwe nibizamini byakozwe - byose byatanzwe mbere yo gusuzuma abakiriya
Niyo mpamvu amakipe yubuhanga muburayi agaragaza QINGDAO QIANGSENYUAN kumateraniro ya pompe yo hanze, nimpamvu OEMs yo mu majyepfo yuburasirazuba bwa Aziya OEM ibizera hamwe na T800 yo hagati ya shitingi ya shaft yo gucukura amabuye y'agaciro. Ntabwo ari amagambo yo hasi. Nukuraho gukuraho rework mbere yuko igishushanyo cya mbere cyubakwa.
Guhitamo Uruganda Rwawe Yatakaye: Reba Kera Agatabo
Baza ibi bibazo bitatu mbere yo gusinya amasezerano:
- Urashobora kunyereka raporo eshatu za nyuma za OES kubintu AMS 5387 watunganije-ukemeza ko byasuzumwe na metallurgiste wawe murugo mbere yo gukina?
- Abakozi bawe ba CMM bahindura iperereza kubikoresho bihanitse mbere ya buri mwanya - cyangwa rimwe gusa mu cyumweru?
- Iyo dutanze igishushanyo hamwe na GD&T guhamagarwa kivuga ASME Y14.5–2018, abajenjeri bawe berekana ibibazo byinganda mumasaha 72 - cyangwa bagategereza kugeza prototype igeze?
Niba ibisubizo bidafite umwihariko - cyangwa wishingikirije kuri "dukurikiza ISO" - komeza urebe. Ubusobanuro nyabwo butangirira aho inyandiko zirangirira kandi urubanza rwabantu rutangirira. Kubisaba gusaba, urwo rubanza rugomba gushyigikirwa nitanura ryibiti, ibisohoka bya spekrometrike, hamwe nubushakashatsi bwa kalibibasi - ntabwo ari ibyemezo gusa.
Ejo hazaza h'ibisumizi byinshi biri mu bikorwa bivangavanze: ishoramari ryashushanyije hafi ya net ishusho yarangiye hamwe no gusya byihuse, hanyuma lazeri yambaye imyenda irinda kwambara. IKORANABUHANGA RYA QINGDAO QIANGSENYUAN rimaze gukora prototyping ya gen-gen-peteroli ikurikira. Ariko intsinzi yuyu munsi iracyashingira kumyifatire-gukurikiranwa kumubiri, indero igereranijwe, nubutwari bwo kuvuga "iki gishushanyo kizacika" mbere yuko ibishashara byambere bikonja.
Nibyo bisobanura ukuri uruganda rwo guta ibishashara.
