I-atomizer Yamanzi Ye-Metal Powder Yensimbi Eyigugu Yegolide Yethusi Isiliva

Kusenezingqinamba eziningi ekuqondeni ubuchwepheshe bokuphrinta be-3D kuzo zonke izici zomkhakha wokukhiqiza waseShayina. Uma sibheka isimo sangempela sokuthuthukiswa, kuze kube manje ukuphrinta kwe-3D akukafinyeleli ekuthuthukisweni kwezimboni ezivuthiwe, kusukela kumishini kuya emikhiqizweni kuya ezinsizeni ezisesigabeni "sethoyizi elithuthukisiwe". Nokho, kusukela kuhulumeni kuya kumabhizinisi e-China, amathemba okuthuthukiswa kobuchwepheshe bokunyathelisa be-3D ngokuvamile aqashelwa, futhi uhulumeni kanye nomphakathi ngokuvamile banaka umthelela wesikhathi esizayo we-3D yokunyathelisa yensimbi ye-atomization ye-pulverizing imishini yobuchwepheshe ekukhiqizeni okukhona kwezwe lami, umnotho, namamodeli wokukhiqiza.

Ngokusho kwedatha yocwaningo, okwamanje, isidingo sezwe lami sobuchwepheshe bokuphrinta be-3D asigxiliwe kumishini, kodwa sibonakala ezinhlobonhlobo zezinto ezisetshenziswayo zokuphrinta ze-3D kanye nesidingo sezinsizakalo zokucubungula i-ejensi. Amakhasimende ezimboni angamandla amakhulu ekuthengeni imishini yokuphrinta ye-3D ezweni lami. Imishini abayithengayo isetshenziswa kakhulu kwezokundiza, i-aerospace, imikhiqizo ye-elekthronikhi, ezokuthutha, ukuklama, ukusungula amasiko nezinye izimboni. Njengamanje, umthamo ofakiwe wamaphrinta we-3D emabhizinisini aseShayina cishe u-500, futhi izinga lokukhula lonyaka lingaba ngu-60%. Noma kunjalo, usayizi wemakethe wamanje ungama-yuan ayizigidi eziyi-100 kuphela ngonyaka. Isidingo esingaba khona se-R&D kanye nokukhiqizwa kwezinto zokuphrinta ze-3D sesifinyelele cishe kumayuan ayizigidi eziyizinkulungwane eziyi-1 ngonyaka. Ngokuthandwa nokuthuthuka kobuchwepheshe bemishini, isikali sizokhula ngokushesha. Ngasikhathi sinye, izinsiza zokucubungula eziphathelene nokuphrinta ze-3D zithandwa kakhulu, futhi ama-ejenti amaningi aphrinta i-3D Inkampani yezisetshenziswa ivuthwe kakhulu enqubeni ye-laser sintering kanye nokusetshenziswa kwemishini, futhi ingahlinzeka ngezinsizakalo zokucubungula zangaphandle. Njengoba intengo yesisetshenziswa esisodwa ngokuvamile ingaphezu kwama-yuan ayizigidi ezingu-5, ukwamukelwa kwemakethe akuphakeme, kodwa insizakalo yokucubungula i-ejensi ithandwa kakhulu.

Iningi lezinto ezisetshenziswa emishinini yezwe yami yokuphrinta ye-3D yensimbi yokunyathelisa i-atomization ihlinzekwa ngokuqondile ngabakhiqizi be-prototyping abasheshayo, futhi ukunikezwa okuvela eceleni kwezinto ezijwayelekile akukakaqaliswa, okuholela ezindlekweni zezinto ezibonakalayo eziphakeme kakhulu. Ngesikhathi esifanayo, alukho ucwaningo mayelana nokulungiswa kwempushana okunikezelwe ekunyatheliseni kwe-3D e-China, futhi kunezidingo eziqinile mayelana nokusabalalisa usayizi wezinhlayiyana kanye nokuqukethwe komoya-mpilo. Amanye amayunithi asebenzisa impushana yesifutho evamile esikhundleni salokho, enokungasebenzi okuningi.

Ukuthuthukiswa nokukhiqizwa kwezinto ezisebenza ngezindlela eziningi kuyisihluthulelo sentuthuko yezobuchwepheshe. Ukuxazulula izinkinga zokusebenza nezindleko zezinto zokwakha kuzothuthukisa kangcono ukuthuthukiswa kobuchwepheshe bokwenza ama-prototyping ngokushesha e-China. Njengamanje, izinto eziningi ezisetshenziswa kubuchwepheshe bezwe lami bokuphrinta be-3D bokuphrinta ngokushesha zidinga ukungeniswa zivela phesheya, noma abakhiqizi bemishini batshale amandla amaningi kanye nezimali zokuzithuthukisa, ezibizayo, okuholela ekwenyukeni kwezindleko zokukhiqiza, ngenkathi izinto zasekhaya ezisetshenziswa kulo mshini zinamandla aphansi nokunemba. . Ukwenziwa kwasendaweni kwezinto zokuphrinta ze-3D kubalulekile.

I-Titanium ne-titanium alloy powders noma izimpushana ze-nickel-based superalloy ezisekelwe ku-cobalt ezinokuqukethwe okuphansi kwe-oxygen, usayizi wezinhlayiya ezinhle kanye ne-sphericity ephezulu kuyadingeka. Usayizi wezinhlayiyana ze-powder ngokuyinhloko -500 mesh, okuqukethwe kwe-oxygen kufanele kube ngaphansi kuka-0.1%, futhi usayizi wezinhlayiyana ufana Njengamanje, i-high-end alloy powder kanye nemishini yokukhiqiza isathembele kakhulu ekuthengeni kwamanye amazwe. Emazweni angaphandle, izinto zokusetshenziswa kanye nemishini ngokuvamile kuyahlanganiswa futhi kudayiswe ukuze bathole inzuzo eningi. Uma sithatha njengesibonelo impushana esekelwe ku-nickel, izindleko zezinto ezingavuthiwe zingamayuan angu-200/kg, intengo yemikhiqizo yasekhaya ngokuvamile iwu-300-400 yuan/kg, kanti intengo yempushana ethengwa kwamanye amazwe ivamise ukuba ngaphezu kuka-800 yuan/kg.

Isibonelo, umthelela nokuvumelana nezimo kokwakheka kwempushana, okufakiwe kanye nezakhiwo ezibonakalayo kubuchwepheshe obuhlobene bemishini yokugaya i-3D yensimbi yokunyathelisa i-atomization powder. Ngakho-ke, ngenxa yezidingo zokusetshenziswa kokuqukethwe komoyampilo ophansi kanye nosayizi wezinhlayiyana ezincane eziyimpushana, kusadingeka ukwenza umsebenzi wocwaningo njengokwakheka kwe-titanium ne-titanium alloy powder, ubuchwepheshe bokugaya i-atomization powder ye-particle size powder powder, kanye umthelela wezimpawu zempushana ekusebenzeni komkhiqizo. Ngenxa yokulinganiselwa kobuchwepheshe bokugaya e-China, kunzima ukulungisa i-powder-grained powder okwamanje, isivuno se-powder siphansi, futhi okuqukethwe kwe-oxygen nokunye ukungcola kuphezulu. Ngesikhathi senqubo yokusetshenziswa, isimo sokuncibilika kwe-powder sijwayele ukungalingani, okuholela ekuquketheni okuphezulu kwe-oxide inclusions kanye nemikhiqizo ye-denser emkhiqizweni. Izinkinga eziyinhloko zezimpushana ze-alloy zasekhaya zisezingeni lomkhiqizo nokuzinza kweqoqo, okuhlanganisa: ① ukuzinza kwezingxenye zempushana (inombolo yokufaka, ukufana kwezingxenye); ② impushana ngokomzimba Ukuzinza kokusebenza (ukusabalalisa usayizi wezinhlayiyana, i-powder morphology, i-fluidity, isilinganiso esixekethile, njll.); ③ inkinga yesivuno (isivuno esincane sempushana engxenyeni yosayizi wezinhlayiyana ezincane), njll.
