I-Metal Powder Water Atomizer Yezinsimbi Eziyigugu Zegolide Zesiliva Zethusi

Kusenezinkinga eziningi ekuqondeni ubuchwepheshe bokunyathelisa nge-3D kuzo zonke izici zomkhakha wokukhiqiza waseShayina. Uma sibheka isimo sangempela sentuthuko, kuze kube manje ukunyathelisa nge-3D ayikafinyeleli ekukhuleni kwezimboni, kusukela emishinini kuya emikhiqizweni kuya ezinsizeni ezisesesigabeni "sethoyizi elithuthukisiwe". Kodwa-ke, kusukela kuhulumeni kuya emabhizinisini aseShayina, amathuba okuthuthukiswa kobuchwepheshe bokunyathelisa nge-3D ayaziwa ngokuvamile, futhi uhulumeni nomphakathi ngokuvamile banaka umthelela we-atomization yensimbi yokunyathelisa nge-3D yesikhathi esizayo ekukhiqizeni, emnothweni, kanye namamodeli okukhiqiza akhona ezweni lami.

Ngokusho kwedatha yocwaningo, njengamanje, isidingo sezwe lami sobuchwepheshe bokunyathelisa nge-3D asigxilile emishinini, kodwa sibonakala ezinhlobonhlobo zezinto ezisetshenziswayo zokunyathelisa nge-3D kanye nesidingo sezinsizakalo zokucubungula izinhlangano. Amakhasimende ezimboni yiwona anamandla amakhulu ekuthengeni imishini yokunyathelisa nge-3D ezweni lakithi. Imishini abayithengayo isetshenziswa kakhulu ezindizeni, ezindizayo, emikhiqizweni kagesi, ezokuthutha, ekwakhiweni, ekudaleni amasiko nakwezinye izimboni. Njengamanje, amandla afakiwe amaphrinta e-3D emabhizinisini aseShayina angaba ngu-500, kanti 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 zokunyathelisa ze-3D sifinyelele cishe kuma-yuan ayizigidi eziyi-1 ngonyaka. Ngokuthandwa kanye nentuthuko yobuchwepheshe bemishini, isikali sizokhula ngokushesha. Ngesikhathi esifanayo, izinsizakalo zokucubungula eziphathisiwe ezihlobene nokunyathelisa nge-3D zithandwa kakhulu, futhi ama-ejenti amaningi okunyathelisa nge-3D Inkampani yemishini ivuthiwe kakhulu enqubweni yokusika i-laser kanye nokusetshenziswa kwemishini, futhi ingahlinzeka ngezinsizakalo zokucubungula zangaphandle. Njengoba intengo yemishini eyodwa ngokuvamile ingaphezu kwezigidi ezi-5 zama-yuan, ukwamukelwa kwemakethe akuphezulu, kodwa insizakalo yokucubungula i-ejensi ithandwa kakhulu.

Iningi lezinto ezisetshenziswa emishinini yokugaya insimbi yokunyathelisa ye-3D ezweni lami ihlinzekwa ngqo ngabakhiqizi be-prototyping esheshayo, futhi ukunikezwa kwezinto ezijwayelekile ezivela eceleni akukaqaliswa, okuholela ezindleleni eziphezulu kakhulu zezinto. Ngesikhathi esifanayo, akukho cwaningo mayelana nokulungiswa kwempuphu olunikezelwe ekunyatheliseni kwe-3D eShayina, futhi kunezidingo eziqinile zokusatshalaliswa kosayizi wezinhlayiya kanye nokuqukethwe komoya-mpilo. Amanye amayunithi asebenzisa i-spray powder evamile esikhundleni salokho, enezinto eziningi ezingasebenzi.

Ukuthuthukiswa nokukhiqizwa kwezinto ezisebenziseka kalula kuyisihluthulelo sentuthuko yezobuchwepheshe. Ukuxazulula izinkinga zokusebenza kanye nezindleko zezinto kuzokhuthaza kangcono ukuthuthukiswa kobuchwepheshe bokuphrinta okusheshayo eShayina. Njengamanje, izinto eziningi ezisetshenziswa kubuchwepheshe bokuphrinta okusheshayo be-3D ezweni lami zidinga ukungeniswa zivela kwamanye amazwe, noma abakhiqizi bemishini batshale amandla amaningi kanye nezimali ukuze bazithuthukise, okubiza kakhulu, okuholela ekwandeni kwezindleko zokukhiqiza, kuyilapho izinto zasekhaya ezisetshenziswa kulo mshini zinamandla aphansi kanye nokunemba. . Ukufakwa kwendawo kwezinto zokuphrinta ze-3D kubalulekile.

Kudingeka izimpushana ze-alloy ze-titanium ne-titanium noma izimpushana ze-superalloy ezisekelwe ku-nickel kanye ne-cobalt ezinokuqukethwe okuphansi kwe-oxygen, usayizi wezinhlayiya ezincane kanye ne-sphericity ephezulu. Usayizi wezinhlayiya ze-powder ngokuyinhloko u--500 mesh, okuqukethwe kwe-oxygen kufanele kube ngaphansi kuka-0.1%, kanti usayizi wezinhlayiya uyafana Njengamanje, i-alloy powder ephezulu kanye nemishini yokukhiqiza isathembele kakhulu ekungenisweni kwamanye amazwe. Emazweni angaphandle, izinto zokusetshenziswa kanye nemishini zivame ukuhlanganiswa futhi zithengiswe ukuze kutholakale inzuzo eningi. Uma sithatha i-nickel-based powder njengesibonelo, izindleko zezinto zokusetshenziswa zingama-yuan angu-200/kg, intengo yemikhiqizo yasekhaya ngokuvamile ingu-300-400 yuan/kg, kanti intengo ye-powder engenisiwe ivame ukuba ngaphezu kwama-yuan angu-800/kg.

Isibonelo, ithonya kanye nokuzivumelanisa nezimo kokwakheka kwempuphu, ukufakwa kanye nezakhiwo zomzimba kubuchwepheshe obuhlobene bemishini yokugaya i-powder yensimbi yokunyathelisa i-3D. Ngakho-ke, ngenxa yezidingo zokusetshenziswa kokuqukethwe okuphansi kwe-oxygen kanye nempuphu encane yosayizi wezinhlayiya, kusadingeka ukwenza umsebenzi wocwaningo njengokwakheka kokwakheka kwempuphu ye-titanium ne-titanium alloy, ubuchwepheshe bokugaya impuphu ye-atomization yegesi yempuphu encane yosayizi wezinhlayiya, kanye nethonya lezimpawu zempuphu ekusebenzeni komkhiqizo. Ngenxa yomkhawulo wobuchwepheshe bokugaya eShayina, kunzima ukulungiselela impuphu encane okwamanje, isivuno sempuphu siphansi, futhi okuqukethwe kwe-oxygen nokunye ukungcola kuphezulu. Ngesikhathi senqubo yokusebenzisa, isimo sokuncibilika kwempuphu sithambekele ekungalinganini, okuholela kokuqukethwe okuphezulu kokufakwa kwe-oxide kanye nemikhiqizo exinene emkhiqizweni. Izinkinga eziyinhloko zama-powder e-alloy asekhaya zisezingeni lomkhiqizo kanye nokuqina kweqembu, okuhlanganisa: ① ukuzinza kwezingxenye zempuphu (inani lokufakwa, ukufana kwezingxenye); ② Ukuzinza kokusebenza kwempuphu ngokomzimba (ukusatshalaliswa kosayizi wezinhlayiya, isimo sempuphu, ukugeleza, isilinganiso esikhululekile, njll.); ③ inkinga yokukhiqiza (isivuno esincane sempuphu engxenyeni encane yosayizi wezinhlayiya), njll.
