Yintoni iteknoloji yokubumba inaliti ye-Metal powder

Yintoni iUkubumba inaliti yomgubo wesinyithiubuchwephesha?Ubuchwephesha bokubumba inaliti yomgubo omncinciinkqubo yokubumba inaliti yomgubo (MNA),piimveliso ze-owder metallurgyezinokuthi zicutshungulwe kwaye zenziwe zikhawulelwe kuluhlu lobunzima be-3 ukuya ku-509. Kwiminyaka yakutshanje, ngenxa yokusetyenziswa kweteknoloji yokucubungula i-ultra-precision, kuye kwenzeka ukuba kusetyenziswe i-molds encinci yokuchaneka ukusebenzisa ngokufanelekileyoinkqubo yokubumba inaliti yentsimbiukwenza izinto ezinzima kumatshini kunye neemveliso ezintsonkothileyo nezincinci kwaye azinakwenziwa ngasemva okanye zicutshungulwe phezulu. Le yindlela micro-MIM (micro-MIM). Iimveliso eziveliswe yindlela ye-MIM ye-micro-MIM ayiyona inxalenye ephambili yeemveliso zendlela ye-MIM kweli nqanaba, kodwa indlela inokusingatha izinto ezinzima-ukusebenza, iimilo eziyinkimbinkimbi kunye neengxenye ezingafuneki ukuqhutyelwa komatshini, ngoko ke uluhlu lwesicelo lwayo kulindeleke ukuba lukhule ngokukhawuleza . Ukusuka kwimbono ye-microItekhnoloji yeMIMkunye nezinto ezisetyenziswa kwiimveliso, ubukhulu beemveliso zayo zingaphantsi kwe-1mm. Kunzima ukuhlengahlengisa ukuchaneka komda kunye nokugqitywa komphezulu weemveliso ngokusebenzisa iteknoloji yokucubungula elandelayo. Ngoko ke, ukuze kuhlangatyezwane nezi mfuno, kuyimfuneko Sebenzisa i-fineness ethile ye-powder ekrwada. Umgubo osetyenziswa kwinaliti yentsimbi ye-mim yesiqhelo unobungakanani besuntswana elimalunga ne-10 m ububanzi, kodwa umthetho we-MIM omncinci ufuna ukusetyenziswa komgubo kunye nobukhulu besuntswana elimalunga ne-3 m. Ukugqitywa komphezulu wemveliso ye-sintered ye-MIM encinci engenanto efunyenwe ngokusebenzisa umgubo ocolekileyo unokufikelela kwi-RaO 0.25m, ngelixa isiqheloiindawo zokubumba inaliti yesinyithiinokufumana kuphela i-RaO 1.2m. I-Metal powder enomlinganiselo we-particle ubukhulu obumalunga ne-39m inokuveliswa ngokusebenzisa amanzi aphezulu-uxinzelelo olusondeleyo kwi-1000kg / cm2 ukuchaphazela umlambo wesinyithi otyhidiweyo, oko kukuthi, indlela ephezulu yoxinzelelo lwe-atomization yamanzi. Le teknoloji iye yaphuhliswa.
