Buyini ubuchwepheshe bokubumba umjovo we-Metal powder

YiniMetal powder umjovo ukubumbaubuchwepheshe?Ubuchwepheshe bokubumba umjovo wempushana Ovamileinqubo yokubumba umjovo we-powder (MINA),pimikhiqizo ye-owder metallurgyezingacutshungulwa futhi zenziwe zikhawulelwe ebangeni lesisindo se-3 kuya ku-509. Eminyakeni yamuva, ngenxa yokusetshenziswa kobuchwepheshe bokucubungula ukunemba kwe-ultra-precision, kuye kwenzeka ukusebenzisa isikhunta esincane sokunemba ukuze kusetshenziswe ngempumeleloInqubo yokubumba umjovo wensimbi ye-mimukwenza izinto ezilukhuni ukuya emshinini kanye nemikhiqizo eyinkimbinkimbi futhi emincane futhi engakwazi ukucubungula noma ukucubungula phezulu. Lena indlela ye-micro-MIM (micro-MIM). Imikhiqizo ekhiqizwe indlela ye-micro-MIM ayiyona ingxenye eyinhloko yemikhiqizo yendlela ye-MIM kulesi sigaba, kodwa indlela ingakwazi ukusingatha izinto okunzima ukucubungula, izimo eziyinkimbinkimbi nezingxenye ezingadingi ukucutshungulwa ngomshini, ngakho-ke uhla lwayo lokusebenza kulindeleke ukuthi lukhule ngokushesha . Ngokombono we-microUbuchwepheshe be-MIMkanye nezinto zokusetshenziswa ezisetshenziswa emikhiqizweni, ubukhulu bemikhiqizo yayo bungaphansi kuka-1mm. Kunzima ukulungisa ukunemba kwe-dimensional kanye nokuqedwa kwangaphezulu kwemikhiqizo ngobuchwepheshe bokucubungula obulandelayo. Ngakho-ke, ukuze uhlangabezane nalezi zidingo, kuyadingeka Sebenzisa inhlawulo ethile yempushana eluhlaza. Impushana esetshenziswa kumjovo ojwayelekile we-mim metal inesilinganiso sosayizi wezinhlayiyana ezingaba ngu-10 m ububanzi, kodwa umthetho we-MIM omncane udinga ukusetshenziswa kwempushana enesilinganiso sosayizi wezinhlayiyana ezingaba ngu-3 m. Ingaphezulu lomkhiqizo osikiwe we-MIM encane engenalutho etholwe ngokusebenzisa impushana enjalo ingafinyelela ku-RaO 0.25m, kuyilapho evamileizingxenye zokubumba umjovo wensimbiingathola kuphela i-RaO 1.2m. Impushana yensimbi enobukhulu obuyizinhlayiyana obuyisilinganiso esingama-39m ingakhiqizwa ngokusebenzisa amanzi anengcindezi ephezulu asondele ku-1000kg/cm2 ukuze ithinte umfudlana wensimbi encibilikisiwe, okungukuthi, indlela yokucindezela amanzi ephezulu. Lobu buchwepheshe benziwe ngezimboni.
