Emsebenzini Wethimba, ukwenza lula ubunkimbinkimbi kusenhliziyweni yokukhiqiza izingxenye zensimbi.Amaqembu ethu okuklama nobunjiniyela asebenza eduze nawe, kuyilapho Isikhungo sethu sesimanjemanje seMetal Technology e-Guangdong sinikeza ubungcweti obungenakuqhathaniswa.Ngokusheshisa nokuguquguquka kokuphrinta kwe-3D kwensimbi, okudlula izindlela ezivamile, siyakusekela kuyo yonke inqubo, noma ngabe i-prototyping noma ukukhiqizwa kochungechunge olugcwele.Ungathembela kithi ukuthi sikulethe imiphumela evelele kusukela ekuqaleni kuze kube sekupheleni.
Okokuqala, umshini we-DMLS usebenzisa i-laser ukucwilisa ungqimba ngalunye embhedeni wempushana yensimbi, uqale ngesakhiwo sokusekela bese kuba ingxenye ngokwayo.Ngemuva kwesendlalelo ngasinye sika ·
i-micro-welding, iplatifomu yokwakha yehla futhi i-recoating blade ibeka ungqimba olulandelayo lwempushana.Le nqubo iyaqhubeka kuze kube yilapho ukwakhiwa kuqedwa.Impushana exegayo isuswa mathupha futhi izingxenye zingaphansi komjikelezo wokwelashwa kokushisa ukuze kudambise ingcindezi.Khona-ke, isakhiwo sokusekela siyasuswa, futhi ingxenye ifakwe isihlabathi futhi ikhishwe.Ingxenye yokugcina ye-DMLS cishe iminyene ngo-100%.
Izinzuzo zokuphrinta kwe-3D yensimbi zihlanganisa ikhono lokudala izingxenye zangokwezifiso eziyinkimbinkimbi ezingenakwenzeka ngezindlela zokukhiqiza zendabuko.
Izinzuzo
Lezi zingxenye zingabuye zenzelwe ukusebenza okuphezulu, isisindo esincane kanye nobunzima bomhlangano obuncishisiwe.Izingxenye eziphrintiwe ze-Metal 3D zinezakhiwo ezinhle kakhulu zomzimba, ngisho nokufaka izinto zokwakha ezinzima emshinini njengama-superalloys ensimbi.
imikhawulo
Izindleko eziphakeme zezinto kanye nezindleko zokukhiqiza zokunyathelisa kwensimbi ye-3D zenza kungafaneleki kahle izingxenye ezikhiqizwa kalula ngezindlela zendabuko.Ngaphezu kwalokho, usayizi wokwakha wezinhlelo zokuphrinta zensimbi ze-3D unomkhawulo ngenxa yesidingo sezimo eziqondile zokwenziwa nokulawulwa kwenqubo.Izingxenye eziklanywe ngaphambilini zingadinga ukushintshwa ukuze kuqinisekiswe ukuhambisana nobuchwepheshe bokuphrinta be-3D bensimbi.
I-SLM ne-DMLS ubuchwepheshe bokuphrinta be-3D obuthuthukisiwe obungakhiqiza izingxenye ezihlukahlukene zezinsimbi nama-alloys ensimbi, okuhlanganisa i-aluminium, insimbi engagqwali, i-titanium, i-cobalt chrome ne-Inconel.Lezi zinto zilungele inhlobonhlobo yezicelo zezimboni kusukela ku-aerospace kuya kwezokwelapha.Nakuba izinsimbi eziyigugu ezifana negolide, iplatinum, i-palladium nesiliva zingase futhi zicutshungulwe, ukusetshenziswa kwazo okuyinhloko kukhawulelwe ekwenzeni ubucwebe.Kodwa-ke, kufanelekile ukuqaphela ukuthi izimpushana zokuphrinta zensimbi ze-3D zibiza kakhulu.Isibonelo, insimbi engagqwali engu-316L powder ibiza cishe u-$350 - $450 ngekhilogremu.Ngakho-ke, isidingo sokunciphisa ingxenye yevolumu kanye nezakhiwo zokusekela kubalulekile ekugcineni izindleko ziphansi ngangokunokwenzeka.Enye yezinzuzo ezibalulekile zokuphrinta kwe-3D yensimbi ukuhambisana kwayo nezinto ezisezingeni eliphakeme njenge-nickel noma ama-cobalt-chromium superalloys.Ukucubungula lezi zinto kusetshenziswa izindlela zokukhiqiza zendabuko kuyinselele kakhulu.Izindleko ezinkulu nokonga isikhathi kungafinyelelwa ngokusebenzisa ukuphrinta kwensimbi kwe-3D ukuze udale izingxenye eziseduze zomumo wenetha ezingase zicutshungulwe ukuze kuzuzwe ukuphakama okuphezulu.Sengiphetha, ukuphrinta kwensimbi ye-3D kunikeza inhlobonhlobo yezinto ezisetshenziswayo ezifanele izinhlelo zokusebenza ezahlukahlukene futhi iyakwazi ukuphatha inselele yezinto ezisezingeni eliphezulu.Kodwa-ke, uhlobo olubizayo lwezimpushana zokunyathelisa zensimbi ze-3D kufanele zicatshangelwe futhi umklamo uthuthukiswe ngokufanele.
