Xa iinjineli zichaza i-resin sand casting factory iinkonzo zezixhobo zetsimbi eziphakamileyo, azikho nje uku-odola iinxalenye-zikhusela ukuzinza kwe-dimensional phantsi kwebhayisikile ye-thermal, i-microstructural consistency kwi-100-kg castings, kunye nokunyamezela kwe-porosity kwiindawo ezithwele uxinzelelo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose ngaphezulu kwe-27,000 ye-cobalt-nickel alloy housings ukususela ngo-2019-nganye ihlolwe ngee-CMM ze-Zeiss zilinganiswe kwi-ISO 10360-2-kwaye safunda ukuba isanti ye-resin ayisiyonkqubo yokubuyela umva. Yeyona ndlela isebenzayo yeejometri ezintsonkothileyo ezinje ngepiston pump cylinder housings apho utyalo-mali lubetha ixabiso lesilingi kunye nesanti eluhlaza kusilela kumphezulu.
Kutheni le nto i-Resin Sand Casting iphumelela kwiMishini-Ebalulekileyo yeHydraulic kunye neMixholo yeMpompo
Amaqela amaninzi okuthenga acinga ukuba isanti yeresin "ichanekile kancinane" kunotyalo-mali. Ukusebenza, sibona okuchaseneyo: xa ukhupha i-AMS 5387 cobalt alloy nozzles kwi-offshore oil pump, i-resin-bonded silica sand ihambisa i-0.3 mm ye-linear tolerance kwi-420-mm diameters-iqinile kunokuba ukuhluka kwegobolondo lotyalo-mali oluqhelekileyo luvumela. Isitixo? Ukulawulwa kokusabela kwe-exothermic ngexesha lokunyanga. Indawo yethu isebenzisa i-amine-cured phenolic urethane binders, hayi iireyini zefuran. Oko kuphelisa i-pickup yesulfure kwi-cobalt alloys, igcina ukuxhathisa ukubola kwiindawo ze-H₂S. Silinganise i-12% yokuhlaselwa kwe-intergranular ephantsi kwiiplagi ezisekelwe kwi-T800 emva kweeyure ze-72 ze-NACE TM0177 zokuvavanya-ngokudityaniswa ngokuthe ngqo kwi-chemistry ye-binder, kungekhona unyango olushushu lwe-post-cast.
Oku kubalulekile kuba imizimba yevalvu yehydraulic ayisileli kwimpazamo enkulu. Bayasilela kwi-micro-shrinkage kwimida phakathi kwamacandelo atyebileyo kunye namancinci-njengalapho i-port yokunceda uxinzelelo idibana ne-flange ekhulayo. Iinjineli zethu zezenjineli zemephu yodidi olushushu zisebenzisa i-MAGMASOFT® ukulinganisa *phambi* kokuvunywa kwepateni. Silungisa i-resin-to-sand ratios ngendawo: i-1.8% ye-binder kwi-core inserts, i-1.2% kwiindonga zangaphandle zokubumba. Isiphumo? I-94% isivuno sokuqala sokupasa kwizindlu zepiston pump cylinder xa kuthelekiswa ne-avareji yoshishino yama-71%.
Udibaniso oluthe nkqo luSombulula iNgxaki "Yokuphosa-Machining Handoff".
Uninzi lweentsilelo azenzeki ekwenziweni okanye ekwenziweni komatshini-kodwa apho zidibana khona. Umthengi wake wasithumelela umzobo we-winch centre shaft roller ene-±0.025 mm engqukuva ubuncinci kwi-120-mm OD. Umthengisi wabo wangaphambili wayiphosa, emva koko wathunyelwa kwivenkile ye-CNC yomntu wesithathu. Irola ijike nge-0.08 mm ngexesha lokuthomalalisa uxinezeleko ngenxa yokuba intsalela yoxinzelelo ayikhange yenziwe phambi komatshini. Senza ngokwahlukileyo: iimetallurgists zethu ziqhuba uvavanyo lwe-tensile kuyo yonke i-ladle egalelwe, emva koko yondla idatha yokuqhelanisa nokutya okuziinkozo kumatshini wethu we-Mazak INTEGREX i-200S we-multi-axis. Sisebenza ngomatshini ngaphakathi kweeyure ezingama-48 ze-shakeout-akukho kulibaziseka ukwaluphala-sisebenzisa iindlela zesixhobo ezilandela i-casting-induced stress vectors. Umjikelo wokugqibela: 0.018 mm. Ngokuqhubekayo.
Oku kudityaniswa kunabela ekulandelekeni kwezinto. Ibhetshi nganye ye-T800 alloy iphethe itikiti lobushushu elinekhowudi ye-QR elidibanisa iicerts zemathiriyeli ekrwada (ASTM A995 Grade 6A), iingxelo zohlalutyo olunyibilikayo, kunye neerekhodi zokugqibela zokuhlolwa kwe-ultrasonic. Akukho zigodo zamaphepha. Akukho kungenelwa ngesandla. Ukuba isiseko sempompo asiphumeleli kwiplanti ye-Southeast Asia yokukhupha ityuwa, sibeka i-3.2 kg yesinyithi esityhidiweyo esisetyenzisiweyo-kwaye sitsale imbali yayo ye-thermal kwi-Siemens SIMATIC PCS 7 DCS i-archive yethu.
Imida Yehlabathi Lokwenyani-Nendlela Esisebenza Ngayo Ngaphakathi Kuyo
Ukubunjwa kwesanti yeresin kunemida enzima. Asiyi kucaphula iinxalenye ezinobunzima bodonga phantsi kwe-8 mm kwi-cobalt alloys-umngcipheko wokuzaliswa kwesikhunta esingaphelelanga kudlula i-40%. Kwaye asisayi kwamkela ii-callouts ze-GD&T ezifuna indawo eyinyani engqongqo kune ±0.1 mm kwiimpawu ezingaphezulu kwe-150 mm ukusuka kwiidatum ngaphandle kokongeza umphezulu wedatha omatshini kwipatheni. Abanye banokuphikisa imveliso ye-CNC kuphela ithintela le miqobo. Kodwa ukwenza i-65-kg yentsimbi yokuphosa kwi-bar eqinile ixabisa i-3.7 × ngaphezulu kwaye ilahle i-68% yezinto eziphathekayo njenge-chips. Indlela yethu ye-hybrid-i-precision casting + i-CNC ejoliswe ekugqityweni-inciphisa ixesha elihamba phambili nge-40% kwiindibano zempompo yemoto yobunjineli ngelixa ibambe i-0.05 mm flatness kwiziseko ze-500-mm.
Sibhala konke ukutenxa. Kwikota yokugqibela, umxhasi waseYurophu ucele i-0.01 mm uburhabaxa bomhlaba kwiplagi ye-cobalt alloy face. Uvavanyo lwethu lubonise iRa 0.8 µm. Esikhundleni sokuthembisa iziphumo ezingenakufikeleleka, sicebise ukupolisha kwe-electrochemical post-machining-ukongeza i-$ 14.30 / inxalenye kodwa ukuhambisa i-Ra 0.05 µm. Ukungafihlisi kubetha ukuba nethemba ngalo lonke ixesha.
Ukukhetha i-resin yakho ye-Sand Casting Factory ayithethi ngexabiso-Imalunga neNkqubo yobunini
Ilungelo i-resin sand casting factory ungumnikazi wekhonkco elipheleleyo: isayensi yezinto eziphathekayo, i-mold physics, ukuqinisekiswa kwe-metallurgical, kunye novavanyo olusebenzayo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, siyayikhaba imizobo ngaphandle kwenkcazelo ye-GD&T—siya kukunceda ukuba uyitolike. Sibuyisela impendulo ye-DFM kwiiyure ze-72, imingcipheko yokubeka iflegi efana nokunyuka okungaboniyo kwiindawo zokunxiba eziphezulu okanye idrafti enganelanga kwiitshaneli zokupholisa zangaphakathi. I-ISO 9001 yethu: Inkqubo ye-2015 ayingomaphepha-iphila i-Cpk yokulandelela kwimilinganiselo ebalulekileyo, kunye nezilumkiso ezizenzekelayo xa amandla enkqubo ehla ngaphantsi kwe-1.33.
Abathengi behlabathi bayasikhetha ngenxa yokuba sithumela iinxalenye ezisebenzayo-hayi nje ukuphosa. Yonke ivalve yoxinzelelo idlula i-100% yovavanyo lwe-hydrostatic kwi-1.5 × ilinganiswe uxinzelelo lokusebenza. Yonke i-cobalt alloy nozzle idlula uhlolo lwedayi nge-ASTM E165. Asizifihli emva “kokuthobela.” Sikubonisa ingxelo yovavanyo yenombolo yakho yolandelelwano.
Ukuba iprojekthi yakho elandelayo ifuna iindawo ezichanekileyo zetsimbi ezisinda kwimijikelo ye-20,000 ye-psi, ukuxhathisa i-slurry e-abrasive, okanye ugcine ulungelelwaniso emva kweminyaka eyi-10 phantsi komhlaba-qalisa nge-resin sand casting factory ephatha i-metallurgy njengobunjineli, kungekhona ubugcisa.
