Xa iinjineli zichaza amacandelo e-aluminiyam kwi-hydraulic manifolds, izindlu zempompo, okanye imizimba yevalve ephezulu yoxinzelelo, ukuzinza kwe-dimensional kunye ne-microstructural consistency ayikhethi-ayinakuxoxisana. Kungenxa yoko le nto ii-OEM ezininzi zaseMntla Melika kunye nezaseYurophu ngoku zivela kwi- ilahleke umzi-mveliso wokugalela i-aluminiyam ephatha ukuphosa utyalo-mali hayi njengenkqubo ezimeleyo, kodwa njengenyathelo lokuqala elichanekileyo kuhambo oluluqilima olulawulwa ngokungqongqo. Siye sabona abathengi babuyela kathathu-okokuqala kwiiprototypes, okwesibini ukuqinisekiswa kwe-medium-batch, okwesithathu kwimveliso epheleleyo-kuba ababoneleli babo bangaphambili babengenakukwazi ukubamba i-± 0.05 mm kwiiflange ezinqabileyo ze-aluminium emva kokunyanga kokushisa. Oyena nobangela? Umsantsa phakathi kobuchule bokuphosa kunye noqeqesho lwasemva komatshini.
Kutheni "i-Wax elahlekileyo" yodwa ayikuqinisekisi ukuchaneka-kwaye kwenza ntoni
I-wax elahlekileyo yokuphosa i-aluminium ihambisa i-geometry esondeleyo-net-shape-kodwa kuphela ukuba ikhonkco lonke lenzelwe ingqibelelo yokusebenza. Kwiziko lethu elise-Qingdao, siqala ngeebhilithi ze-AMS 4117 okanye ze-A380 eziqinisekisiweyo kwi-ASTM B179, emva koko siqinisekise ubume benkozo ngesampulu ye-metallographic phambi kokudityaniswa kokungunda kweqokobhe. Okubaluleke kakhulu, asiyi kukhupha izixhobo zepatheni ye-wax: iinkosi zethu ze-aluminium zangaphakathi ze-CNC zisivumela ukuba silungelelanise ii-angles zedrafti kunye nezikhundla ze-gating ngaphakathi kwe-0.02 mm-ezibalulekileyo xa siphosa izindlu ze-cylinder ezineziteshi zokupholisa zangaphakathi phantsi kwe-2.5 mm ubukhulu bodonga.
Siye saqaphela ukuba i-70% ye-dimensional drift kwi-aluminiyam yotyalo-mali yotyalo-mali iyenzeka ngexesha le-waxing kunye nokutshiswa-kungathululi. I-kilns yethu ecwangcisiweyo i-ramp kwi-0.8 ° C / min ukuya kwi-1050 ° C, ibambe imizuzu engama-90 ukuphelisa i-wax eseleyo ngaphandle kokuqhekeka iigobolondo ze-silica-alumina. Olo lawulo lubaluleke kakhulu kumacandelo afana ne-piston pump cylinder housings, apho ukothuka kwe-thermal ngexesha lokutshiswa kudala iintanda ezincinci ezithi kamva zisasazeke phantsi koxinzelelo lwebhayisekile.
Ngokungafaniyo neevenkile zokugalela esantini eziphatha i-aluminiyam “njengelula ukugalela,” sibeka iliso kwiqondo lobushushu lokunyibilika ngaphakathi ± 3°C sisebenzisa iiprobe zokuntywiliselwa ezimbini ze-thermocouple-kwaye siyala nayiphi na ibhetshi apho umxholo we-hydrogen udlula i-0.12 ml/100g (elinganiswa ngovavanyo lokuqina kwevacuum). Oku akukho overkill; yindlela esifumana ngayo amandla okuqina ≥310 MPa kwizindlu ze-A380 eziphathwa nge-T6 ngelixa sigcina ubude>3.5%.
Apho Ukusatyelwa Kuphele khona kunye nobuNjineli bokwenyani buqala
Nantsi into eninzi ilahleke umzi-mveliso wokugalela i-aluminiyam Uluhlu aluyi kukuxelela: ukuchaneka kwendlela yotyalo-mali yehla ngokukhawuleza ngaphaya kwe-300 mm nakuwuphi na umlinganiselo omnye. Yingakho iseli yethu ye-CNC ihlala iimitha ukusuka kumgca wokuphosa-kungekhona ngaphesheya kwendawo yokugcina impahla. Sisebenza ngomatshini iindawo zokutywina ezibalulekileyo, imingxunya enyukayo, kunye nokuzala ngaphakathi kweeyure ezi-4 zokushukuma, sinciphisa ukuphumla koxinzelelo kwimatrix ye-aluminium.
Sisebenzisa ii-five-axis machining ngaxeshanye kumacandelo afana ne-winch center shaft rollers, apho ukugxila okuphakathi kwe-120 mm OD kwijenali kunye ne-ID bore ye-65 mm kufuneka kubambe i-0.015 mm iyonke yokufundwa kwesalathisi. Akukho unyango olushushu emva komatshini olusetyenziswayo ngaphandle kokuba luchaziwe-kuba ukufudumeza kwakhona kuphazamisa i-fine-grained surface layer eyenziwe ngexesha lokuqina okulawulwayo. Endaweni yoko, sisebenzisa isiqabu soxinzelelo lokungcangcazela imizuzu engama-30 ngaphambi kokuhlolwa kokugqibela kweCMM.
Iprotocol yethu yokuhlola ayiqhutywa kuluhlu-luqhutywa ngumsebenzi. Kwiivalvu zoxinzelelo, asiqinisekisi nje ii-callouts ze-GD&T kodwa amazinga okuvuza kwesihlalo esichasene nemigangatho ye-ISO 5208 yoDidi A. Inxalenye nganye iphethe ileyibhile yokulandeleka edibanisa inombolo yayo yothotho kwii-certs zemathiriyeli ekrwada, iilogi zesithando somlilo, iingxelo zeCMM, kunye nedatha yovavanyo lwe-helium.
Xa iCobalt Alloys ingena kuMfanekiso-kwaye kutheni iAluminiyam isakhokelela
Abanye bacinga ukuba iinxalenye ze-cobalt-nickel zithetha ukulahla i-aluminiyam. Hayi apha. Sihlala siphosa izindlu ze-aluminium ezidibanisa i-cobalt alloy nozzles (AMS 5387) ngokucokisekileyo ngokucokisekileyo-ukuqinisekiswa ngovavanyo lwebhondi ye-ultrasonic. Umzimba we-aluminium uphatha umthwalo wesakhiwo; i-cobalt ifake ixhathisa ukhukuliseko kwi-220 ° C ubushushu be-fluid. Le ndlela ye-hybrid inciphisa iindleko nge-38% ngokuchasene ne-monolithic cobalt casting ngelixa idibana ne-API RP 14E imida yesantya.
Sakhe i-17 iterations ye-T800-based based pump plunger guide ring-nganye ihlanjululwe ngokusekelwe kuhlalutyo lokungaphumeleli kwintsimi ukusuka kwi-oil rigs ye-offshore. Kodwa ezo zifundo ziye zayiphucula ngokuthe ngqo inkqubo yethu yokuphosa i-aluminium: ulawulo olungqongqo lwesithuba phakathi kwe-interdendritic sinciphise i-porosity kwimizimba yevalvu ye-A380 evezwe kulwelo olune-H₂S. Ubuchwephesha bezinto eziphathekayo abukho-siloed-i-cross-pollinated.
Ucwangciso lwethu lwemveliso ebhityileyo luqinisekisa ukuba ixesha lokukhokela kweprototype lihlala lingaphantsi kweentsuku ezingama-21-kwanakwijometri ezintsonkothileyo ezifuna iicores zeceramic. Kwiodolo yevolumu, sigcina isitokhwe se-buffer yeealloyi eziqhelekileyo kunye nemathiriyeli yeqokobhe, ukuze ukulandeleka kwemathiriyeli kungabi ngumqobo wokuhambisa.
Ukukhetha Iqabane, Hayi nje uMboneleli
Ukuba iprojekthi yakho elandelayo yokuphosa i-aluminiyam ibandakanya iindonga ezibhityileyo, iipaseji zangaphakathi, okanye ukunyamezelana okuqinileyo kwiimpawu zoomatshini, buza le mibuzo ngaphambi kokuba usayine i-PO:
- Ngaba ungabonisa iingxelo ze-CMM ezibonisa ukunyanzeliswa kwe-flange kwi-150 × 150 mm yeflange?
- Ngaba wenza uhlalutyo lwe-hydrogen kuyo yonke into enyibilikayo-okanye ngeveki kuphela?
- Ngaba inkqubo yakho ye-CNC yenziwa ngaphakathi, okanye ikhutshelwe ngaphandle kumthengisi owahlukileyo?
- Yiyiphi inkqubo yakho ebhaliweyo yokuqinisekisa utshintsho olungundoqo kumacandelo angenanto?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphendula zone ngedatha eqinisekisiweyo-hayi iincwadana. Asithengisi iinkonzo zokuphosa. Sihambisa amacandelo e-aluminium asebenzayo aphila kwi-10,000 + imijikelezo yoxinzelelo kwiinkqubo ze-hydraulic, i-5-year deployments kwiimpompo zaselwandle, kunye nokusebenza ngokuqhubekayo kwii-winches zemoto yobunjineli. Oko kuthembeka kuqala ngaphambi kokuba i-wax inyibilike-kwaye iphele kuphela emva kokuba umsebenzisi wakho wokugqibela asayine.
