拖泵(beng)制造工藝
錐齒輪加工工藝流程(cheng)和難點控(kong)制
為(wei)確保齒輪熱處理(li)時(shi),能(neng)夠減小變(bian)形(xing)并獲得均勻的(de)組織(zhi)和(he)較(jiao)好的(de)機(ji)(ji)械性能(neng),在(zai)(zai)機(ji)(ji)加(jia)工(gong)(gong)前,先(xian) 對(dui)齒坯進(jin)(jin)(jin)行高(gao)溫(wen)正(zheng)火(huo)(huo)預處理(li),可以使組織(zhi)得到細化,并減小滲(shen)碳(tan)(tan)淬火(huo)(huo)時(shi)零件(jian)的(de)變(bian)形(xing),同(tong)時(shi)還有利于 提(ti)高(gao)切(qie)削性能(neng)。正(zheng)火(huo)(huo)后轉(zhuan)機(ji)(ji)加(jia)工(gong)(gong),先(xian)在(zai)(zai)車(che)床(chuang)上(shang)對(dui)齒坯外(wai)圓、端面進(jin)(jin)(jin)行粗(cu)、精加(jia)工(gong)(gong)后,在(zai)(zai)臥(wo)式銑(xian)床(chuang)上(shang)進(jin)(jin)(jin) 行銑(xian)齒,然后在(zai)(zai)插(cha)床(chuang)上(shang)插(cha)鍵(jian)槽,全部機(ji)(ji)加(jia)工(gong)(gong)完成后,進(jin)(jin)(jin)行滲(shen)碳(tan)(tan)淬火(huo)(huo)和(he)低溫(wen)回火(huo)(huo)處理(li),進(jin)(jin)(jin)行后序處 理(li)。該零件(jian)的(de)工(gong)(gong)藝流程為(wei):正(zheng)火(huo)(huo)→車(che)削→銑(xian)齒→插(cha)鍵(jian)槽→滲(shen)碳(tan)(tan)淬火(huo)(huo)及退火(huo)(huo)→噴砂→防銹處理(li)。工(gong)(gong)藝難點為(wei)銑(xian)齒和(he)熱處理(li)工(gong)(gong)序。
