Xa iinjineli zichaza iinxalenye ze-aluminiyam kwi-hydraulic manifolds, izindlu zempompo, okanye iinkqubo ze-winch zemoto, azifane ziqale "ngokuphosa isanti." Baqala ngengxaki: ukuhamba ngebhayisikile ye-thermal, ukunyamezela kwe-GD & T, ukunyaniseka kwengcinezelo kwi-350 + bar-kunye ne-zero margin ye-micro-porosity okanye i-dimensional drift. Kulapho a isanti ukugalela aluminiyam umzi-mveliso iyeka ukuba ngumthengisi kwaye ibe lulwandiso loyilo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sibone iintsilelo ezintathu eziphindaphindiweyo kwiiprojekthi zokuphosa isanti ye-aluminium-kungekhona kwi-foundry ye-Foundry embi, kodwa ngenxa yokulindela okungalunganga kwi-handoff yobunjineli.
Okokuqala: ukuthatha "i-aluminiyam" ithetha i-A380. Akunjalo. Kwivenkile yethu, i-75% yesanti ye-aluminiyam ye-aluminiyam isebenza kwi-A383 okanye i-custom-modified 319 variants-ingakumbi kuphuculo lwe-fluidity kwiziseko zempompo zodonga olubhityileyo kunye nokusebenza kakuhle emva konyango lobushushu be-T6. Okwesibini: ejongene nokuhanjiswa kweenkozo zesanti yokungunda. Sisebenzisa i-silica edibeneyo ye-resin ene-45-75 µm elawulwayo-kungekhona ngenxa yokuba isemgangathweni, kodwa ngenxa yokuba inqumle uburhabaxa bomphezulu (Ra) nge-30% ngokubhekiselele kwisanti yendabuko eluhlaza, ukunciphisa ixesha lokusila emva kokuphosa kwiiflange zezindlu ze-cylinder. Okwesithathu: ukutsiba ukulinganisa kwangaphambili kwe-FEA yokuqina kokuqina. Omnye umthengi waseMntla Melika usithumelele umzobo wezindlu wempompo yepiston onobambo oluyi-22 mm elikufutshane nodonga oluyi-6 mm. Ukulinganisa kubonise indawo eshushu esemngciphekweni omkhulu. Sicebise ukuba kufakwe indawo ebandayo—kwaye sasusa i-100% yemingxuma yangaphakathi eshwabeneyo engaphumelelanga kwibhetshi yabo yokuqala yeX-reyi.
Yintoni eyahlula umntu okwaziyo isanti ukugalela aluminiyam umzi-mveliso ukusuka kwenye ehambisa iindawo ezibalulekileyo zobuthunywa? Ukuhlanganiswa ngokuthe nkqo-kungekhona nje ukuphosa, kodwa ikhonkco elipheleleyo ukusuka ekukhethweni kwe-alloy ukuya ekuqinisekiseni ukusebenza. Sifumana kuphela i-ingots eziqinisekisiweyo ze-aluminium ezineengxelo zovavanyo olupheleleyo (ASTM B179, EN 1706), emva koko senze uhlalutyo lwe-OES kwibhetshi nganye enyibilikayo. Akukho ngaphandle. Iiseli zethu ze-CNC zoomatshini zihlala iimitha ukusuka kwisikhululo sokushukuma-ke ii-castings zihamba ngokuthe ngqo kwi-fixturing ngaphandle kokuphumla koxinzelelo lweqondo lobushushu. Yiloo ndlela esibamba ngayo i-±0.05 mm kwiindawo ze-valve body port, nakwi-420 mm yezindlu ezinde. Asizami "ukuzama" ukubetha ukunyamezela. Silawula indlela ye-thermal ukusuka ekuthululeni ukuya ekugqibeleni ukusika.
- Ukuhambelana kweCobalt-alloy: Ewe-sihlala siphosa i-aluminium malunga nokufakwa kwe-cobalt-nickel (AMS 5387, T800) kwiindibano zempompo ye-hybrid. Undoqo kukugalela okulandelelanayo kunye nolawulo lobushushu obuphakathi kobuso phakathi kwe ±15°C kwindawo ye-eutectic.
- GD&T ukuphunyezwa: Siqinisekisa isikhundla, iprofayili, kunye nokuphuma sisebenzisa i-Zeiss CONTURA CMMs-kungekhona nje ekuhlolweni kokugqibela, kodwa emva komatshini onzima kwaye kwakhona emva kokunciphisa uxinzelelo.
- Ukulandeleka: Yonke i-casting iphethe ikhowudi ye-QR efakwe kwi-laser edibanisa kwi-melt log yayo, ingxelo ye-x-ray, ukuqina kobunzima, kunye nesatifikethi se-dimensional-akukho mzila wephepha, akukho zirekhodi ezilahlekileyo.
Abanye bayaxoxa ukuba ukuphoswa kwesanti akukwazi ukuhambelana nokuphosa utyalo-mali kwiijometri ezintsonkothileyo ze-aluminiyam. Kodwa ukuntsokotha akukho malunga nokubalwa kwenxalenye-kumalunga noxinzelelo olusebenzayo. I-winch center shaft roller idinga ukuhanjiswa kobunzima obulinganayo, ukugqitywa komphezulu womgangatho wokuzala kwi-OD, kunye nokulungelelaniswa kweqhosha elichanekileyo kubude beemitha ezi-1.2. Izibambo zesanti ezingcono kunotyalo-mali xa ubukhulu bodonga buhluka ukusuka kwi-8 mm ukuya kwi-45 mm. Ngoba? Kuba silawula izinga lokupholisa ngeengqele zalapha kunye nemikhono yokugquma—hayi nje imathiriyeli yokungunda. Sihambise i-210 kg ye-aluminium castings kunye ne-Cpk> 1.67 kwi-bores ebalulekileyo, iqinisekiswe phantsi komthwalo kwi-400 bar hydraulic test rigs.
Ukuhanjiswa kwelizwe lokwenyani kuxhomekeke kwizinto ezimbini uninzi lwabathengi abangazihoyiyo: ukulungela izinto eziphathekayo kunye nenkqubo ekuhleni. Sigcina i-A383 kunye ne-319 i-alloys kwiibhetshi ze-500 kg-icazululwe kwangaphambili, i-pre-dried, ilungele ukunyibilika kwiiyure ze-24 zokuqinisekisa umyalelo. Kwaye sabelana ngohlaziyo lwemveliso yexesha lokwenyani: hayi nje "ukuqala ukusasazwa," kodwa "indibano yokubumba igqitywe ngo-09:22, ukugalela okucwangciselwe u-14:00, i-shakeout elindelekileyo ngo-18:40." Oko kubonakala kuvumela amaqela okuthenga alungelelanise izinto, amaqela e-QA acwangcise iindawo zokubeka iCMM, kwaye iinjineli zoyilo ziqinisekisa ubungakanani benqaku lokuqala ngaphambi kokuba kuqale ukusebenza kwesibini.
Ukuba iprojekthi yakho elandelayo yokuphosa i-aluminiyam ifuna ngaphezu kwephepha lokucaphula-ukuba ifuna ingqiqo ye-metallurgical, i-casting-machining interface plan, kunye nokuthotyelwa okubhaliweyo kwi-oyile & negesi okanye i-hydraulics ehambayo-ufuna iqabane eliphatha ukuphosa isanti njengenkqubo yobunjineli, kungekhona inyathelo lempahla. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngaloo ndlela-kungekhona ngenxa yokuba ivakala kakuhle kwiwebhusayithi, kodwa ngenxa yokuba iivalve zoxinzelelo ziyavuza, iipompo zezindlu ziyaqhekeka, kwaye i-winch shafts iyasilela xa iingcinga zithatha indawo yedatha. Sakha iinxalenye ze-aluminium ezisinda kwimijikelo yokuqala ye-10,000-kunye ne-100,000 elandelayo.
