Iyo ba injeniyeri bagaragaje yatakaye ibishashara bikozwe mu ruganda serivisi kubice byingenzi byicyuma, ntabwo bagura ifumbire gusa - barimo kubona ibipimo bisubirwamo, kugenzura microstructural, no kwizerwa kumikorere mubihe bikabije. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze ibicuruzwa bisaga 12,000 byashizwe mu mibiri ya hydraulic valve, cobalt-alloy pump nozzles, hamwe na pisitori ya pompe ya piston - buri gice gisaba kwihanganira mm 0,05 mm, gukurikiranwa neza, hamwe na AMS 5387. Ubwo ntabwo ari ubushobozi bwa theoretical. Niko bigenda iyo ukoresheje ibicuruzwa 47 bikurikiranye bya T800 ya cobalt ishingiye kuri casting nta cyiciro na kimwe cyo kwangwa.
Kuki ibishashara byatakaye byatoranijwe guhitamo uruganda bihindura byose-kubuzima bwigice cyawe, ntabwo ari imiterere yacyo gusa
Amakipe menshi atanga amasoko afata ishoramari nk "agasanduku kirabura": kohereza ibishushanyo, gutegereza ibyumweru 6-8, hanyuma ugenzure. Ariko muri sisitemu ya hydraulic yumuvuduko mwinshi cyangwa ibikoresho bya peteroli na gazi yo hanze, cluster imwe ya microporosity mumwanya wintebe ya valve irashobora gukurura kunanirwa. Twabonye abakiriya batatu batugarukira nyuma yo kunanirwa kwabacuruzi ba mbere-sibyo kuko uwabitanze bwa mbere yabuze ibikoresho, ariko kubera ko bafataga igishushanyo mbonera nko kwimura geometrie, ntabwo ari moderi yubushyuhe bwamashanyarazi. Uruganda rwacu rwatakaye rwibishashara rutangirana no kwigana gukomera - ntabwo ari ibishashara. Buri cyobo kibumbabumbe kibara ibintu byihariye bigabanya kugabanuka, kugabanuka-guterwa n’imivurungano, hamwe n’ibipimo byo gukonja byaho. Kuri AMS 5387 cobalt alloy, bivuze guhinduranya geometrie ya 1.8 ° kugirango wirinde gutandukanya dendritic kumarembo. Kubishingwe bya pompe idafite ibyuma, bivuze gushyira ibyambu bya termocouple muburyo bwa ceramic shell ibumba kugirango yemeze igihe cyo gukomera hamwe nubuhanuzi bwa FEA.
Ntukeneye ubushobozi bwa "byinshi"-ukeneye kugenzura bihagaritse kugenzura aho bifite akamaro kanini
Bamwe mubatanga isoko yo gukora ibumba, abandi batanga imashini, hamwe nubuvuzi bwinshi bwo hanze. Uku gucamo ibice bitera icyuho: casting irashobora gutsinda igenzura ryikigereranyo ariko ikananirwa kwipimisha gukomera kuko uwakoraga itanura yakoresheje igipimo gitandukanye nikigaragara. Ku kigo cyacu cyujuje ISO i Qingdao, itsinda rimwe rishinzwe gukora ibishushanyo mbonera, guhimba ibumba ry’ibumba, kurangiza neza CNC, no kuvura ubushyuhe bwa vacuum - byose biri munsi yinzu imwe, hamwe nuburinganire bwa metero. Mugihe umukiriya wu Burayi yari akeneye imibiri 240 yumuvuduko wumuriro muri 316 ibyuma bitagira umuyonga hamwe na Ra ≤ 0.4 µm hejuru yubuso hejuru yimbere yimbere, twasibye gusya kabiri. Nigute? Mugukoresha ceramic shell ibumba hamwe na 5-axis yinzira yigana kwihanganira kontour ya nyuma - hanyuma ugakoresha dewaxing igenzurwa no gutwikwa kugirango ubungabunge ubudahemuka binyuze muri casting. Igisubizo: 98.7% umusaruro-wambere wambere, umusaruro wa zeru, no gutanga muminsi 22 aho kuba 38 byavuzwe.
Igiciro nyacyo cya "gisanzwe" cyatakaye ibishashara bishushanya ubufatanye bwuruganda
Abakiriya bakunze kubaza bati: "Urashobora guhuza igiciro cyabacuruzi bacu?" Igisubizo cyacu gihora ari kimwe: “Reka tugerageze byombi.” Umwaka ushize, twakoresheje ibigeragezo kumpande 18 zicyuma kimwe - GD&T imwe, ibikoresho bimwe, idirishya ryo gutanga. Umucuruzi uhendutse ucuruza yatanzwe mugihe - ariko 31% byasabye gusya nyuma yo gutara kugirango bihuze kwihanganira umwirondoro. Ibyacu byari 92% byemewe-guterana-guterana. Kubera iki? Uburyo bwabo bwo kubumba bwakoresheje intoki zishashara; iyacu yakoresheje inshinge zikoresha hamwe nigihe cyo kugenzura umuvuduko wa cavity. Itandukaniro rya mm 0,03 muburyo bwo guhuza ibice ntabwo ryagaragaye muri raporo za CMM kugeza nyuma yo gutunganya-mugihe igiciro cyakuweho $ 220 kuri buri gice. Igiciro nyacyo ntabwo ari igiciro cyibice. Nibiciro byose byubutaka kubice bikora, harimo imirimo yo kugenzura, gusiba ibyakozwe, hamwe ningaruka zingengabihe. Twanditse buri gutandukana - kumanuka kugeza kumatara nyayo yubushyuhe kuri buri giceri kibumba - kugirango umenye neza impamvu igice cyawe gikora.
Ibizakurikiraho ntabwo ari ubushobozi-ni ubuhanga bwimbitse
Turimo kwagura ibishashara byatakaye byashushanyije ubushobozi bwuruganda-ntabwo twongeyeho imashini, ahubwo twongere ubwenge bwubwenge. Kuri ubu, turimo kwemeza uburyo bwo kuvanga ibice bya T800 bivanze: gushora imari bikurikirwa no guhitamo laser yo gushonga hejuru yimyenda. Iyi ntabwo ari ikinamico R&D. Ikemura ikibazo cyububabare nyabwo: abakiriya bakeneye imashini ya cobalt-nikel ya shitingi ifite ubuso bukomeye (HRC 58-62) ariko ingirabuzimafatizo (ong 35%). Uburyo bwa gakondo busaba gukurikiranwa gukomeye-gukomeretsa geometrike yoroheje. Igisubizo cyacu gitanga imitungo yombi mumurimo umwe, hamwe na NDT yuzuye kuri buri cyiciro. Niba gusaba kwawe kugusaba byombi Kurwanya ruswa ikabije na Ingaruka zo kwihanganira - cyangwa niba uwaguhaye isoko ubu afata AMS 5387 nk "ikindi kintu kitagira umwanda" - ukeneye umufatanyabikorwa ubona ifumbire atari igikoresho, ahubwo nkigice cya mbere cyakozwe mubikorwa. Nuburyo butangira neza.
