Ukuveliswa kwe-Sand casting kuhlala kuyindlela ebiza kakhulu yokuvelisa i-complex, i-high-integrity metal parts-ingakumbi xa ubukhulu bodonga budlula i-6 mm, ubunzima benxalenye budlula i-5 kg, okanye imiqulu yonyaka iwela phakathi kwe-10 kunye ne-500 units. Kodwa asikuko konke ukugaywa kwesanti kuyalingana. Siye sabona abathengi abaninzi befumana i-castings enobume obungahambelaniyo benkozo, i-porosity engalindelekanga kwi-flanges ethwele umthwalo, okanye i-dimensional drift emva konyango lobushushu-kuphela ukufumanisa unobangela osisiseko yayingengomgangatho wezinto eziphathekayo okanye ubushushu besiseko, kodwa ukuguquguquka kobumbano kwiiprints eziphambili.
Kutheni iSand Casting isaphumelela kuShishino oluchanekileyo
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siqhuba zombini isanti kunye nemigca yokuphosa utyalo-mali-kodwa sigcine ukugatywa kwesanti kwiindawo apho ubunzima be-thermal, i-mechanical damping, okanye i-geometry enkulu ifuna: i-piston pump cylinder housings ukuya kwi-1,200 mm ubude, i-winch yemoto ye-winch yeziko le-shaft rollers 2000 kunye ne-4 yoxinzelelo lwe-valve ye-2 bar 2. Ezi ayizo "izithuba ezingenanto" ezilindele ukwenziwa komatshini onzima. Zikufuphi ne-net-shape-shape ebanjwe ukuya ku-±0.3 mm kumphezulu wedatha ebalulekileyo, kunye nokugqitywa komphezulu kuqinile njenge-Ra 6.3 µm kujongano olunomatshini.
Isitshixo asikokutsiba ukuchaneka- siyayifakela kwangethuba. Inkqubo yethu yokwenziwa kwesanti iqala nge-CNC-machinen pattern tooling (kungekhona umthi okanye ugwebu), isebenzisa isanti edityaniswe nentlaka ye-silica enobumanzi obulawulwayo. <2.1% kunye ne-permeability 110-130, kwaye isebenzise iliso lexesha langempela lokubeka iliso ngexesha lokubumba. Eli nyathelo lokugqibela lilodwa linciphisa iziphene ezingundoqo nge-74% xa kuthelekiswa ne-ramming-data eqinisekisiweyo kwiibhetshi ezininzi ze-hydraulic ezili-18 ngaphezulu kwe-Q3 2023.
Izigqibo ezine zobuGcisa ezenza okanye ezaphula ukuCasa kwakho
Uninzi lweentsilelo lubuyela emva kolunye lwezikhetho ezine ezenziwe ngaphambi kokuba ukhozo lokuqala lwesanti luchukumise iflask:
- Isicwangciso sesibonelelo sepateni: I-Standard 1% yokunciphisa imbuyekezo iyasilela kwi-cobalt-nickel alloys efana ne-AMS 5387. Sisebenzisa izibonelelo ezihlukeneyo-0.92% axial, 0.85% radial-ye-T800-based based pump housings ukubamba i-GD & T callouts kwiijenali ezithwele.
- Ingqiqo yoyilo lokunyuka: Ayisekelwanga kwivolumu, kodwa ukuqina-ixesha elihambelanayo. Silinganisa iigophe zokupholisa sisebenzisa i-MAGMAsoft, emva koko sibeke izinyusi ezifakwe kwi-insulated kuphela apho ixesha lokuqiniswa kwendawo lehla ngaphantsi kwe-87% yesiseko secandelo elinzima kakhulu.
- Ukubekwa kokuvula umngundo: I-Vents iya kwi-12 mm ukusuka kwi-cope / core parting lines-not randomly-ilungelelaniswe ukubaleka iindlela zokuhamba kwegesi ezifakwe kwimaphu ngovavanyo lokubola kwe-vacuum.
- Ixesha le-Shakeout: Ungaze "xa upholile ngokwaneleyo ukubamba." Kwimibhobho yentsimbi engaphezulu kwe-80 mm ubukhulu becandelo, siyalibazisa i-shakeout de ubushushu bomhlaba bufike kuma-520°C ±15°C. Phambuka ngaphezu kwe-20 ° C, kunye ne-spikes yoxinzelelo olushiyekileyo 3.2 × kwisiseko sempompo yokufaka iilugs.
Xa iSand Casting igqithisa uTyalo-mali-kwaye xa lungekho
Ezinye iinjineli ziyasilela ekufakeni utyalo-mali ukuze "zichaneke." Kodwa lo ngumgibe. I-investment casting igqwesa ngaphantsi kwe-15 kg nangaphantsi kwe-150 mm max dimension-kodwa izabalaza kunye neepaseji zangaphakathi ezinkulu kune-Ø25 mm okanye ukuguqulwa kodonga ngaphezu kwe-45 mm ngaphandle kweenyembezi ezishushu. Kutshanje siphinde saqhuba i-cobalt alloy nozzle order: izinto ezifanayo ze-AMS 5387, ukushicilelwa okufanayo, iinkqubo ezimbini. Ukuchithwa kotyalo-mali kunikeze isivuno se-92%-kodwa kufuna iiyure ze-11 zokucoca i-EDM ngenxalenye yokususa intsalela ye-ceramic kwi-320 mm yangaphakathi. Ukugalelwa kwesanti? I-98% yesivuno, i-zero post-cast bore finishing efunekayo, i-37% ephantsi iyonke yeendleko zokuhlala.
Nangona kunjalo-ukugaywa kwesanti kusilela ngokukhawuleza xa ufuna iRa ≤1.6 µm njenge-cast surfaces, okanye iimpawu ezincinci kuno-Ø3 mm ezinobunzulu-ku-diameter>4. Abo baya ngqo kumatshini we-CNC ukusuka kwibha eqinileyo. Asinyanzeli-zifake iinkqubo. Iphepha lethu lokucaphula libonisa olu ngquzulwano ngaphambili, kunye neendlela ezizezinye ezibekwe ngokwexabiso lilonke ngokweyunithi yokusebenza-hayi ngekhilogram okanye ngeyure.
Ijongeka njani i-Real-World Quality Control
"I-ISO-certified foundry" ithetha encinci ukuba ukuhlolwa kuyeka kwi-tensile bar. Kwiziko lethu le-Qingdao, yonke indawo yokwenziwa kwesanti ijongwa iindawo ezine ezinyanzelekileyo:
- Uhlalutyo lwebhetshi yesanti engenayo: Ukuhanjiswa kwe-Sieve, umxholo wodongwe, kunye nelahleko-kwi-ignition efakwe kwi-ASTM C1107.
- Ukuqinisekiswa kobulukhuni bokubumba kwangaphambili: Ukufundwa kwe-Shore Scleroscope ≥72 kuyo yonke i-cope/core surfaces, erekhodiweyo kwindawo yokuphosa.
- I-post-shakeout ye-ultrasonic scanning: I-100% yokuhlolwa kwe-volumetric ye-subsurface iyancipha kumacandelo abalulekileyo-akukho sampuli.
- Ukuqinisekiswa kokugqibela kwe-CMM: Ingxelo epheleleyo ye-GD&T ngokuchasene nomzobo wokuqala, kubandakanywa ne-datum yokuhlola uzinzo emva konyango lobushushu bokunciphisa uxinzelelo.
Sigcina ukulandeleka okugcweleyo: amanani esanti ekrwada, izigodo ezinyibilikayo, iimephu zokuqina komngundo, kunye ne-CMM yamafu-zonke zibotshelelwe kwinombolo yakho ye-PO. Akukho ngaphandle. Yiloo ndlela esiqinisekisa ngayo ukuba imizimba yevalve yoxinzelelo iyahlangabezana neemfuno ze-API 6D kuzo zonke iikontraka ezintathu eziluncedo zaseMntla Melika-ngaphandle kokusilela kwintsimi enye kwiinyanga ezingama-22.
