Iyo abajenjeri bagaragaje ibice bya aluminiyumu ya hydraulic manifolds, amazu ya pompe, cyangwa imibiri yumuvuduko mwinshi wa valve, ituze ryimiterere hamwe na microstructural guhuza ntabwo ari ubushake-ntibishobora kuganirwaho. Niyo mpamvu OEM nyinshi zo muri Amerika y'Amajyaruguru n'Uburayi zituruka kuri a yatakaye ibishashara bya aluminium ibyo bifata ishoramari ntabwo ari inzira yihariye, ahubwo ni intambwe yambere itomoye mugikorwa gikomatanyije cyane. Twabonye abakiriya bagaruka inshuro eshatu-ubanza kuri prototypes, icya kabiri cyo kwemeza icyiciro-giciriritse, icya gatatu cyo gukora ibicuruzwa byose-kubera ko abatanga isoko mbere batashoboraga gufata mm 0,05 mm kuri aluminiyumu yuzuye urukuta nyuma yo kuvura ubushyuhe. Intandaro? Ikinyuranyo hagati yubushobozi bwo gukina na disipuline yo gutunganya nyuma.
Kuki "Ibishashara byatakaye" wenyine ntabwo byemeza neza neza-Kandi Niki
Ibishashara byatakaye bya aluminiyumu bitanga hafi ya net-ishusho ya geometrie - ariko iyo urunigi rwose rwakozwe muburyo bwuzuye. Ku kigo cyacu i Qingdao, duhera kuri fagitire ya AMS 4117 cyangwa A380 yemewe ya ASTM B179, hanyuma tukagenzura imiterere yintete dukoresheje icyitegererezo cya metallografiya mbere yo guteranya ibishishwa. Icy'ingenzi, ntabwo dushushanya ibikoresho byerekana ibishashara: murugo rwacu CNC yakozwe na aluminiyumu ya aluminiyumu itwemerera guhindura inguni zimyanya nimyanya yo kwinjirira muri mm 0,02 - birakomeye mugihe utera amazu ya silinderi hamwe numuyoboro ukonjesha imbere munsi yuburebure bwa mm 2,5.
Twabonye ko 70% yo gutembera murwego rwo gushora imari ya aluminiyumu bibaho mugihe cyo guta ibishashara no gutwikwa-ntibisuke. Amatanura yacu ashobora gutegurwa kuri 0.8 ° C / min kugeza kuri 1050 ° C, gufata iminota 90 kugirango ukureho ibishashara bisigaye utabanje kumena ibishishwa bya silika-alumina. Ibyo kugenzura bifite akamaro kanini kubice nka pisitori ya pisitori yububiko bwa pisitori, aho ihungabana ryumuriro mugihe cyo gutwika ritera micro-crack nyuma ikwirakwizwa nigitutu cyizuba.
Bitandukanye n'amaduka yo guta umucanga afata aluminiyumu "byoroshye gusuka," dukurikirana ubushyuhe bwo gushonga muri ± 3 ° C dukoresheje ibipimo bibiri byo kwibiza mu mazi - kandi twanze icyiciro icyo aricyo cyose aho hydrogène irenga 0,12 ml / 100g (bipimwa n'ikizamini cya vacuum). Ibi ntibirenze urugero; nuburyo tugera ku mbaraga zingana ≥310 MPa mumazu ya T6 yakozwe na A380 mugihe dukomeza kuramba> 3.5%.
Aho Casting irangirira nubuhanga nyabwo butangirira
Dore ibyo cyane yatakaye ibishashara bya aluminium urutonde ntiruzakubwira: ishoramari ryo guta neza ryangirika vuba kurenza mm 300 murwego rumwe. Niyo mpamvu selile yacu ya CNC yicaye metero uvuye kumurongo wa casting-itari hakurya yububiko. Dukora imashini ikomeye yo gufunga ibintu, gushiraho umwobo, no gutwara bores mu masaha 4 nyuma yo kunyeganyega, kugabanya kugabanuka kwa stress muri matrix ya aluminium.
Dukoresha eshanu-axis icyarimwe icyarimwe kubice nka winch center shaft rollers, aho kwibanda hagati yikinyamakuru 120 mm OD na 65 mm ID bore bigomba kuba bifite 0,015 mm byasomwe byose. Nta gutunganya ubushyuhe nyuma yo gutunganyirizwa gukoreshwa keretse bisobanuwe - kuko gushyushya bihagarika igicucu cyiza cyakozwe mugihe cyagenzuwe. Ahubwo, dukoresha imbaraga zo guhindagurika kuminota 30 mbere yubugenzuzi bwa nyuma bwa CMM.
Igenzura ryacu protocole ntabwo rikorwa na lisiti-ikoreshwa. Kubijyanye nigitutu cyumuvuduko, ntitwemeza gusa guhamagarwa kwa GD&T ahubwo igipimo nyacyo cyo kumeneka cyicaro ugereranije na ISO 5208 Icyiciro A. Buri gice gitwara ikirango gikurikirana gihuza nimero yacyo hamwe nibikoresho fatizo, ibiti by'itanura, raporo ya CMM, hamwe namakuru yikizamini cya helium.
Iyo Cobalt Alloys Yinjiza Ishusho - Nimpamvu Aluminium ikomeza
Bamwe batekereza ko ibice bya cobalt-nikel bisobanura kureka aluminium. Ntabwo ari hano. Twakunze gutera inzu ya aluminiyumu ihuza cobalt alloy nozzles (AMS 5387) dukoresheje imashini iboneye - igenzurwa no gupima ultrasonic. Umubiri wa aluminiyumu ukora umutwaro wubatswe; gushiramo cobalt birwanya isuri ku bushyuhe bwa 220 ° C. Ubu buryo bwa Hybrid bugabanya ibiciro 38% na monolithic cobalt casting mugihe wujuje imipaka ya API RP 14E.
Twubatsemo 17 itera ya T800 idasanzwe-ishingiye kuri pomp plunger yayobora impeta-imwe yatunganijwe hashingiwe ku isesengura ryatsinzwe mu murima uva mu ruganda rwa peteroli rwo hanze. Ariko ayo masomo yatezimbere uburyo bwacu bwo guteranya aluminiyumu: kugenzura neza intera intera intera interineti byagabanije ubukana mumibiri ya A380 ya valve ihura na H₂S yuzuye amazi. Ubuhanga bwibikoresho ntibucecekeshwa-bwandujwe.
Igenamigambi ryacu ribyara umusaruro utuma prototype iyobora iguma munsi yiminsi 21 - ndetse no kuri geometrike igoye ikenera ceramic cores. Kubitondekanya amajwi, dukomeza buffer ububiko bwibisanzwe hamwe nibikoresho byigikonoshwa, kubwibyo gukurikirana ibintu ntabwo bihinduka icyuho cyo gutanga.
Guhitamo Umufatanyabikorwa, Ntabwo Atanga gusa
Niba umushinga wawe wa aluminiyumu ukurikira urimo urukuta ruto, inzira nyabagendwa, cyangwa kwihanganira gukomeye kubintu byakorewe imashini, baza ibibazo mbere yo gusinya PO:
- Urashobora kwerekana raporo za CMM zerekana ko ziteye hejuru ya 150 × 150 mm ya flange?
- Ukora isesengura rya hydrogène kuri buri kintu cyashonga - cyangwa buri cyumweru gusa?
- Porogaramu yawe ya CNC ikorerwa murugo, cyangwa igahabwa umucuruzi wihariye?
- Nubuhe buryo bwanditse bwo kugenzura ihinduka ryibanze mubice bidafite ishingiro?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. asubiza uko ari ane hamwe namakuru yemewe - ntabwo ari udutabo. Ntabwo tugurisha serivisi za casting. Dutanga ibikoresho bya aluminiyumu ikora irokoka 10,000+ yumuvuduko muri sisitemu ya hydraulic, imyaka 5 yoherejwe muri pompe zo mu nyanja, hamwe no gukomeza gukora mumashanyarazi yimodoka. Ukwo kwizerwa gutangira kera mbere yuko ibishashara bishonga-bikarangira nyuma yumukoresha wawe wa nyuma.
