Xa iinjineli zicacisa i-cobalt-nickel alloy components for high-pressure hydraulic valves okanye i-AMS 5387 yezindlu zepompo, azigcini nje uku-odola iindawo-zibophezela ukuzinza kwe-dimensional phantsi kwe-thermal cycling, imfezeko ye-microstructural emva kokunyangwa kobushushu, kunye nokunyamezela kwe-porosity kwi-cast-bearing castings. Yiyo loo nto"utyalo-mali kunye ne-precision casting factory limited” ayisiyo inkcazo eqhelekileyo-yimfuno esebenzayo. Kwaye yiyo kanye le nyaniso yokusebenza echaza indlela QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isondela kulo lonke uphononongo lomzobo, izinto ezininzi, kunye nokuhlolwa kweCMM.
Kutheni le nto iNdlela yokuCasa iyalela iNtsebenzo-hayi indleko nje
Sibone iiprojekthi ezininzi kakhulu zisilela-hayi kuyilo olubi, kodwa ekukhetheni inkqubo engafanelekanga. Indlu yesilinda yempompo yepiston eyenziwe ngomatshini ukusuka kwinkunkuma yebha eqinile i-68% yemathiriyeli ekrwada, yazisa uxinzelelo olushiyekileyo, kwaye iyasokola ngokuchaneka kwecontour yangaphakathi ngaphaya kwe ± 0.05 mm. Ukwenziwa kotyalo-mali kuyayitshintsha i-equation: ijiyometri ekufutshane ne-net-shape, ulawulo lokuqinisa ulwalathiso, kunye nokuhambelana kwesinyithi kwiibhetshi. Kwi-QINGDAO QIANGSENYUAN, ukuphosa utyalo-mali akusiyo inketho enye phakathi kwabaninzi-yisiseko se-cobalt-based T800 nozzles, i-AMS 5387 imizimba yevalve, kunye ne-non-standard winch center shaft rollers apho ubukhulu bodonga buhluka ukusuka kwi-4.2 mm ukuya kwi-28 mm kwicandelo elinye. I-Sand casting ibamba amacandelo anzima-impompo iziseko ukuya kuthi ga kwi-120 kg-kodwa kuphela xa idityaniswe namaziko omatshini e-CNC ayakwazi u-5-axis contouring kwi-as-cast surfaces eqiniswe kwi-HRC 42. Akukho kulungelelaniswa. Akukho loop yokuphinda isebenze.
Ukudityaniswa okuthe nkqo kulinganiswa kwiiMicrons-Hayi nje ngamaSebe
Ababoneleli abaninzi bakhupha unyango lobushushu. I-QINGDAO QIANGSENYUAN ingumnini weprofayili yesithando somlilo-kwaye iyayiqinisekisa ngokwe-AMS 2750E. Abanye i-subcontract surface finishing. Apha, i-electropolishing, i-HVOF yokwambathisa, kunye nokupasa kwenzeka phantsi kophahla olunye, kunye nokulandeleka okupheleleyo ukusuka kwi-ID ye-billet eluhlaza ukuya kwingxelo yokugqibela yovavanyo lwesitshizi setyuwa. Olo ludibaniso luzisa iziphumo ezithathu ezibambekayo: Okokuqala, ukugqwethwa kwe-thermal kuhlala ngaphantsi kwe-0.03 mm kwizindlu ze-cylinder ezingama-320-mm-diameter emva kokufakwa kwesisombululo. Okwesibini, ii-callouts ze-GD & T ezifana nokunyamezela isikhundla Ø0.02 mm @ MMC bamba ngokuqhubekayo-nakwi-cobalt-nickel alloys kunye ne-450 HB ubulukhuni. Okwesithathu, ixesha lokukhokela kwii-odolo zomthamo ophakathi (i-50-300 iipcs) zehla nge-37% ngokubhekiselele kwiintambo zokubonelela eziqhekezayo. Awufumani ulawulo ngokongeza i-handoffs. Uzuza ngokuziphelisa.
Isiqinisekiso seMaterial ayingoMsebenzi wePhepha-yiNkqubo ye-Inshurensi
"Izinto eziqinisekisiweyo" azithethi nto ukuba ingxelo yovavanyo lokusila ayihambelani nenani lobushushu eligximfizwe kwi-casting. I-QINGDAO QIANGSENYUAN izingqinisiso ezinqamlezileyo zonke i-cobalt alloy ingot engenayo ngokuchasene nezatifikethi zomthengisi *phambi* kokunyibilika-kungekhona emva. Bagcina ulungelelwaniso lobugcisa kunye nabavelisi bezinto eziziinkozo kwimida yobungakanani beenkozo ze-AMS 5387 (ASTM E112 Udidi lwesi-4 ubuncinci), kwaye baqinisekise ukuxhathisa kwe-intergranular corrosion per ASTM A262 Practice E on every lot. Xa umthengi waseYurophu ecela ukulandeleka kwi-EN 10204 3.1, iqela alizange likrazule-litsale uhlalutyo lwe-spectrographic olugciniweyo, ii-curves zovavanyo olunzima, kunye neengxelo ze-metallography ezisukela kwiinyanga ezili-18. Isiqinisekiso sokwenyani sihlala kwidatha-hayi iifolda.
Ukuthembeka kokuhanjiswa kuqala kuMzobo woPhononongo-hayi iDokhi yokuThumela
Intsebenziswano yobunjineli bokuqala ikhusela ukungaphumeleli kwenqanaba kade. Ngexesha lamva nje leprojekthi yaseMntla Melika yeendibano zempompo engaselunxwemeni, i-QINGDAO QIANGSENYUAN iphawule ngempazamo yokupakishwa kwe-GD&T: ukukhutshwa okukhankanyiweyo kwiplagi ye-T800 yangqubana nokufezekiswa kwee-engile zoyilo lokungunda ekufakweni kotyalo-mali. Esikhundleni sokucaphula "njengoko-kutsalwa," bacebise ulwakhiwo oluhlaziyiweyo lwedatum-eqinisekisiweyo kunye nokulinganisa-kwaye bahambisa iinxalenye zenqaku lokuqala elidibana nokusebenza kwetywina elisebenzayo kwibha ye-420. Lowo ngumahluko phakathi "kokuhanjiswa kwexesha" kunye "nokuhanjiswa kwexesha lokuqala." Abaphathi beprojekthi yabo abalandeleli nje imihla-babeka imephu yokuxhomekeka kwendlela ebalulekileyo: izinga lokupholisa unyango lobushushu vs. Ngee-odolo zeprototype, oko kuthetha ukuqinisekiswa okusebenzayo ≤12 iintsuku zokusebenza. Ukuveliswa kwakhona, kuthetha ukuthunyelwa kweveki okuzinzile-akukho nto imangalisayo, akukho ntlawulo ekhawulezayo.
Kwiinjineli ezichaza amacandelo apho ukusilela kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho, ibinzana elithi “utyalo-mali kunye ne-precision casting factory limited” ifanele ibonise isakhono esiqinisekisiweyo—hayi ulwimi lokuthengisa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ibonisa ukuba ngolawulo olunokumetwa: iimicrons zokuphinda-phindeka kwe-dimensional, ukuthotyelwa kwesinyithi esibhaliweyo, kunye noqeqesho lonikezelo olusekelwe kubunini benkqubo-hayi kwizinto zokusebenza. Ngexesha elizayo xa uvavanya umboneleli ngeevalvu ze-cobalt-alloy, izindlu zempompo, okanye ii-castings ezinobunjineli, buza imibuzo emibini: Iphelela phi i-traceability yabo yemathiriyeli? Kwaye luqala phi uxanduva lwenkqubo yabo?
