Xa iinjineli zicacisa i-cobalt alloy components for hydraulic valves, izindlu zempompo, okanye imibhobho ephezulu yokunxiba, abakhethi nje izinto eziphathekayo-bakhetha isiqinisekiso sokusebenza. Eso siqinisekiso sibambe kuphela ukuba i umzi-mveliso we-cobalt alloy ukuhambisa inxalenye ye-metallurgical consistency, dimensional fidelity, kunye nokuqinisekiswa okusebenzayo-hayi nje kube kanye, kodwa kuyo yonke ibhetshi, yonke ijometri, wonke umjikelo wonyango lobushushu.
Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngolindelo olungahambelaniyo phakathi kwezinto zobunjineli kunye nobuchule bomgangatho wevenkile. Umthengi waseJamani wakha wasithumelela umzobo weplagi ye-cobalt ye-AMS 5387 ene-±0.005 mm GD&T callouts kunye nemfuneko yokugqiba umphezulu weRa 0.4 µm. Umthengisi wabo wangaphambili wayicaphula njenge "machineble" - emva koko wahambisa iiterations ezintathu ezineentanda ezincinci kufutshane negxalaba lokutywina emva konyango lobushushu. Oyena nobangela? Ukulawulwa okungonelanga kwimbali ye-thermal ngexesha lesisombululo se-annealing, idityaniswe yi-toolpath-induced residual stress. Ayingokusilela komatshini oko. Kukusilela kweenkqubo-enye eqala ixesha elide ngaphambi kokusikwa kokuqala.
Imveliso ye-cobalt ye-alloy yokwenyani ifuna ukudityaniswa ngokuthe nkqo, hayi ulungelelwaniso lwabathengisi. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., iinxalenye ze-cobalt-nickel zihamba ngaphandle komthungo ukusuka kwi-T800 eqinisekisiweyo okanye i-AMS 5387 billet ngokusebenzisa utyalo-mali (kwiipaseji ezintsonkothileyo zangaphakathi), i-multi-axis CNC machining (kunye ne-in-process CMM yokuqinisekisa kwii-datums ezibalulekileyo), optical optical underspecting kunye ne-HIP Uphahla oluhambelana ne-ISO. Akukho handoffs. Akukho kuguquguquka kwebhetshi kwibhetshi kulwakhiwo lweenkozo. Akukho ngqikelelo malunga nokuhanjiswa kwe-carbide. Siqinisekisa iicerts zezinto ezikrwada *phambi * kokusika, ukubeka iliso kwi-atmospheres ye-furnace ngexesha lokwenyani ngexesha lonyango lobushushu, kunye nemephu yomphezulu wengqibelelo kusetyenziswa i-profilometry-hayi nje amaxabiso arhabaxa, kodwa ukuwohloka, i-lay direction, kunye nobunzulu be-deformation yangaphantsi komhlaba.
- Ukuchaneka kokuphosa kubaluleke kakhulu apho ijometri idibana nomsebenzi: Isiseko sethu sempompo ye-cobalt ye-sand-cast ibambelele kwi-± 0.15 mm kwii-flanges ezinyukayo-nangona emva kokunciphisa uxinzelelo-kuba sibonisa i-shrinkage yokuqinisa ukuqina * kunye * nokuguqulwa kwesikhunta, kungekhona nje inxalenye yejometri.
- Ukutshiza akukho malunga nokususa isinyithi-kukugcina ingqibelelo: Kwimibhobho ye-cobalt alloy ene-ID ye-0.8 mm kunye nezihlalo ezi-35 ° ze-tapered, sisebenzisa izixhobo ezifakwe kwidayimane kunye nokuhanjiswa kwe-cryogenic epholileyo, kungekhona i-oyile yezikhukhula. Ubomi besixhobo buhla nge-40%, kodwa uxinzelelo lwe-surface compressive luyanda i-22%-i-trade-off esiyibhala kwaye sabelane nabathengi ngaphambili.
- Ukulandeleka akungomaphepha-kukuphendula okusekwe kwifiziksi: Yonke icandelo le-AMS 5387 liphethe irekhodi edibeneyo ye-QR ebonisa ukuhlalutya kwe-melt, i-curves yokuvavanya i-tensile ukusuka kubushushu bayo obuchanekileyo, imephu yobunzima kuyo yonke i-cross-section, kunye neengxelo ze-CMM ezibophelelwe kwiindawo eziqingqiweyo ze-CAD-kungekhona nje ukudlula / ukuhluleka iiflegi.
Abanye banokuthi i-cobalt alloy ye-offshore ivelisa umngcipheko ongamkelekanga: ixesha elide lokukhokela, izithuba zonxibelelwano, ukuqina kwe-QA okungaguqukiyo. Kodwa sifumene okuchaseneyo xa inkqubo yoluleko ithatha indawo yejografi njengomgcini-sango osemgangathweni. Isixhobo se-oyile saseMntla Melika i-OEM yanciphisa i-valve assembly scrap ukusuka kwi-11% ukuya kwi-0.7% emva kokutshintshela kwiziko lethu le-cobalt alloy shaft rollers-kungekhona ngenxa yokuba sisebenzise i-cobalt "engcono", kodwa ngenxa yokuba inkqubo yethu ye-hybridi yokuphosa isuse umsantsa phakathi komphezulu we-as-cast kunye nogqatso lokugqibela. Sisebenza ngomatshini ngaphakathi kwe-0.03 mm yokwakheka komnatha, emva koko sisebenzise ukupasa okukodwa kokugqiba ngembuyekezo yesixhobo esiqinisekisiweyo. Ayilophuculo olongezelelekileyo olo. Kukuchaza kwakhona ukuba kuthetha ukuthini "ukunyamezelana okuphosiweyo".
Yintoni eyahlula umntu othembekileyo umzi-mveliso we-cobalt alloy ukusuka kumthengisi wempahla ayikho umthamo okanye ixabiso-yindlela abaphatha ngayo izinto ezingenakuxoxisana: ukulandelwa kwezinto eziphathekayo phantsi kwinani lobushushu be-ingot, ukutolika kwe-GD & T ebamba iingxabano zesakhelo se-datum * phambi * kokusika, kunye nokuzimisela ukuphuhlisa imijikelo yonyango lobushushu kunye ne-metallurgist yakho. Asihlangani nje ne-AMS 5387; silandelela indlela iqashiso ngalinye elisebenza ngayo ngokuchasene ne-ASTM E112 ubungakanani beenkozo, i-E140 microhardness gradients, kunye ne-E1096 yokuchasana nokugqwala kwe-corrosion kwindawo efanisiweyo yenkonzo. Loo datha yazisa yonke isicatshulwa-kungekhona njengeebhulethi zentengiso, kodwa njengegalelo elisebenzayo kwi-FMEA yakho.
Ukuba icandelo lakho elilandelayo le-cobalt alloy kufuneka liphile kwi-20,000 ye-psi pulsation cycle, i-abrasive slurry flow, okanye i-650 ° C ukuvezwa okwethutyana, qalisa ngemibuzo eveza isakhono: Ngaba unokubonelela ngeelog ezigcweleyo zokunyanga ubushushu kwilogi nganye? Ngaba iingxelo zakho ze-CMM zibandakanya iiplani zokutenxa kwi-vector-kungekhona nje amafu? Ngaba inkqubo yakho yokuphosa iya kwamkela amajelo okupholisa angaphakathi ngaphandle kokutshintsha okungundoqo? Le ayiyomiqobo. Basisiseko. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uziphendula ngedatha-hayi izithembiso. Ngenxa yokuba kwimveliso ye-alloy echanekileyo, ukuthembela akwakhelwanga kwiincwadana. Yenziwe kuyo yonke i-cool-down elawulwayo, ilinganiswe kuyo yonke i-micron yokuchaneka kwendawo, kwaye ibonakaliswe xa inxalenye isebenza-kungekhona kwibhentshi, kodwa kwintsimi.
