Xa iinjineli zichaza a umzi mveliso wokulahla wotyalo-mali olulahlekileyo kwiindawo zetsimbi eziphakamileyo, azithengi nje i-castings-zikhusela ukuphindaphinda kwe-dimensional, ukulawulwa kwe-microstructural, kunye nokuthembeka okusebenzayo phantsi kweemeko zenkonzo ezigqithisileyo. Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngobuchule bokuphosa obungahambelaniyo. Indlu yevalve edlula ukuhlolwa kweCMM kwiqondo lokushisa elingaphakathi inokujika emva konyango lobushushu ukuba i-Foundry ayinayo ukuqinisekiswa kwenkqubo yokushisa edibeneyo. Umbhobho we-cobalt alloy unokudibana neekhemikhali ephepheni kodwa ungaphumeleli ukuxhathisa ukhukuliseko lwenkonzo ukuba ulwakhiwo lweenkozo khange lubekwe iliso kulo lonke ugalelo. Yingakho ukuchaneka akuchazwanga ngokunyamezela kuphela-kwakhiwe ekuhambeni komsebenzi.
Kutheni iLahlekile i-Wax Investment Casting ifuna ukuDityaniswa okuthe nkqo-hayi nje iFoundry
Utyalo-mali lugqwesile apho ukugaywa kwesanti kungenakukwazi: iindonga ezibhityileyo, iipaseji ezintsonkothileyo zangaphakathi, ii-callouts eziqinile ze-GD&T, kunye nokugqitywa komphezulu ocolekileyo (Ra ≤ 1.6 µm). Kodwa ezo zibonelelo ziyawa ngaphandle kokudityaniswa okuqinileyo phakathi kokwenza ipateni, ukwakha iqokobhe, ukudityaniswa, ukudubula, ukugalela, kunye nomatshini wokuphoswa emva kokuphoswa. Kwiziko lethu eQingdao, asikhupheli nawaphi na kula manyathelo. Silawula ikhonkco elipheleleyo-ukusuka kwisixhobo se-silicone kwiipatheni ze-wax ukuya kwi-vacuum-assisted ceramic shell drying, ukusuka kwii-ovens zedewax ezilawulwayo zobushushu ukuya kwi-inert-gas yokugalela i-AMS 5387 cobalt alloy kwi-1,480 ° C. Kutheni ibalulekile nje loo nto? Kuba intsalela yewax ibangela ukuqhekeka kweqokobhe. Ukomiswa kweqokobhe elingalinganiyo kumema i-porosity. Ukothuka kwe-thermal ngexesha le-dewaxing kudala i-microfractures engabonakaliyo kwi-X-ray kodwa ibulala phantsi koxinzelelo lwe-cyclic. Silinganise ukuya kuthi ga kwi-22% yokunciphisa isivuno sokuqala xa ukuthembeka kweqokobhe kungaqinisekiswanga nge-ASTM F2897 nganye.
Apho Ubuchwephesha bezinto eziphathekayo buhlula abathengisi kumaqabane
Uninzi lwabaseki baphosa intsimbi engatyiwayo okanye intsimbi. Bambalwa abaphatha i-T800 cobalt-based alloys-okanye benze oko ngaphandle kokuncama machinability. Siqhube ngaphezulu kwe-1,400 yobushushu bemveliso ye-AMS 5387 ukusukela ngo-2019, nganye iqinisekisiwe nge-OES spectroscopy kunye ne-batch-traceable yonyango lokunyanga ubushushu. Abathengi bahlala bebuza: “Ungakwazi ukubamba ±0.025 mm kwindlu yesilinda yepiston eyi-320 mm?” Ewe-kodwa ngenxa yokuba simatshini *emva* kokuthomalalisa uxinzelelo naphambi kokuguga kokugqibela. Ukuba siyayiphosa, yinyange ngokushushu, emva koko ulinde iiyure ezingama-72 phambi kokuba umatshini, uxinzelelo olushiyekileyo luyayigqwetha ibhore. Asilitsibi elo nyathelo. Siphinde siphephe iindlela ezimfutshane eziqhelekileyo: akukho "generic" cobalt alloy substitutions, akukho zintsimbi zokuzalisa ngaphandle kwe-spec zokulungiswa kwe-weld, akukho misebenzi yesibini engabhalwanga. Yonke iplagi ye-cobalt alloy, yonke inxalenye yempompo engekho emgangathweni, iphethe iicerts zemathiriyeli ezigcweleyo, iingxelo zovavanyo lokuqina, kunye nokuqina kwemephu kuzo zonke iindawo ezibalulekileyo.
Ukuziphatha ngokwenkqubo yeHlabathi yokwenyani-hayi nje iziqinisekiso
I-ISO 9001 ziziteki zetafile. Into ebalulekileyo kukuba ukuqina kuguqulela njani inxalenye yakho. Iprothokholi yethu yokuhlola iqala ngokuqinisekiswa kwe-billet engenayo-hayi nje iziqinisekiso ze-mill, kodwa uvavanyo lwe-ultrasonic lwe-subsurface discontinuities. Ngexesha lokuphosa, i-thermocouples ibeka iliso kwi-mold preheat kunye nentsimbi yokugalela ubushushu ngexesha lokwenyani. Emva kwe-shakeout, yonke i-casting ijongwa ngokungena kwedayi (ASTM E165) kunye neradiography (ASTM E94) phambi komatshini orhabaxa. Ukuhlolwa kokugqibela kubandakanya ukuskena kwe-CMM yazo zonke iimpawu ze-GD&T, umlinganiselo we-optical weendawo zokutywina, kunye novavanyo olusebenzayo-njengokuhlola uxinzelelo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza kwimizimba yevalvu. I-OEM enye ye-hydraulic yaseYurophu inciphise ukungaphumeleli kwentsimi nge-68% emva kokutshintshela kwizindlu zethu ze-cylinder-kungekhona ngenxa yokuba ukunyamezela kuqinisiwe, kodwa ngenxa yokuba senze imephu kunye nokulawula iivektha eziphazamisayo kwi-12 ye-thermal cycles.
Ukukhetha i-Right Lost Wax Investment Casting Factory Kuthetha Ukubuza imibuzo eLungileyo
Sukubuza "Ngaba unaso isatifikethi se-ISO?" Buza: "Uqinisekisa njani amandla eqokobhe ngaphambi kokuba udikwe?" Musa ukubuza "Yeyiphi i-alloys oyenzayo?" Buza: “Ndibonise iilog zakho ezintathu zokugqibela zonyango lobushushu ze-AMS 5387—kunye neziphumo ezingqinelanayo zokunyameka kobushushu.” Musa ukubuza "Liliphi ixesha lakho lokuhamba?" Buza: "Uyilawula njani idimensional drift phakathi kokusalwa kunye nokuphela kwe-450 mm iwinch centre shaft roller?" Iimpendulo zibonisa ukukhula komsebenzi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphendula loo mibuzo ngeenkqubo ezibhaliweyo, kungekhona izithembiso. Sisebenzela abavelisi bempompo yendawo yeoli yaseMntla Melika abafuna ukuthotyelwa kwe-ASME B16.34, ababoneleli ngemoto yobunjineli baseJamani abafuna ukulandeleka kwe-EN 1559-3, kunye nabakhi bempompo abakhethekileyo baseMazantsi-mpuma aseAsia abafuna iRa ≤ 0.8 µm umphezulu wokutywina—zonke zisuka kumgca omnye odibeneyo. Ukuphosa ngokuchanekileyo akukho malunga nokuphelisa ukuhluka. Kumalunga nokulinganisa, ukwenza imephu, kunye nokulawula-bonke ubushushu, yonke indawo, yonke indawo.
