拖泵(beng)制造工(gong)藝
錐齒(chi)輪加(jia)工(gong)工(gong)藝流程和難(nan)點控制
為(wei)確保齒輪熱(re)處(chu)理(li)時(shi)(shi),能夠(gou)減小變形并(bing)獲得均勻的(de)組(zu)織(zhi)和較好的(de)機(ji)(ji)械性(xing)(xing)能,在(zai)(zai)機(ji)(ji)加(jia)工(gong)前,先 對(dui)齒坯進(jin)(jin)行(xing)(xing)高溫正火(huo)(huo)預處(chu)理(li),可以使組(zu)織(zhi)得到細化,并(bing)減小滲碳(tan)淬(cui)(cui)火(huo)(huo)時(shi)(shi)零件的(de)變形,同(tong)時(shi)(shi)還有利(li)于 提高切削性(xing)(xing)能。正火(huo)(huo)后轉機(ji)(ji)加(jia)工(gong),先在(zai)(zai)車床(chuang)上(shang)對(dui)齒坯外(wai)圓、端面(mian)進(jin)(jin)行(xing)(xing)粗、精加(jia)工(gong)后,在(zai)(zai)臥式銑床(chuang)上(shang)進(jin)(jin) 行(xing)(xing)銑齒,然后在(zai)(zai)插床(chuang)上(shang)插鍵槽(cao),全部機(ji)(ji)加(jia)工(gong)完成后,進(jin)(jin)行(xing)(xing)滲碳(tan)淬(cui)(cui)火(huo)(huo)和低溫回火(huo)(huo)處(chu)理(li),進(jin)(jin)行(xing)(xing)后序處(chu) 理(li)。該零件的(de)工(gong)藝流程為(wei):正火(huo)(huo)→車削→銑齒→插鍵槽(cao)→滲碳(tan)淬(cui)(cui)火(huo)(huo)及(ji)退火(huo)(huo)→噴(pen)砂→防銹處(chu)理(li)。工(gong)藝難(nan)點(dian)為(wei)銑齒和熱(re)處(chu)理(li)工(gong)序。
