拖(tuo)泵制造工藝
錐(zhui)齒輪加工工藝流程(cheng)和難點控制
為(wei)(wei)確保齒輪熱處(chu)(chu)(chu)理(li)(li)時(shi)(shi),能(neng)夠(gou)減(jian)小(xiao)變形(xing)并獲得均勻的(de)組(zu)織和較好的(de)機械(xie)性能(neng),在機加(jia)(jia)工(gong)前,先(xian) 對齒坯進(jin)(jin)行(xing)(xing)高(gao)溫(wen)正火預處(chu)(chu)(chu)理(li)(li),可以使組(zu)織得到細化,并減(jian)小(xiao)滲碳(tan)淬火時(shi)(shi)零件(jian)的(de)變形(xing),同時(shi)(shi)還有利于 提高(gao)切削性能(neng)。正火后轉機加(jia)(jia)工(gong),先(xian)在車床上(shang)對齒坯外圓、端(duan)面進(jin)(jin)行(xing)(xing)粗、精加(jia)(jia)工(gong)后,在臥式銑床上(shang)進(jin)(jin) 行(xing)(xing)銑齒,然后在插(cha)床上(shang)插(cha)鍵(jian)槽(cao),全部機加(jia)(jia)工(gong)完成后,進(jin)(jin)行(xing)(xing)滲碳(tan)淬火和低(di)溫(wen)回火處(chu)(chu)(chu)理(li)(li),進(jin)(jin)行(xing)(xing)后序處(chu)(chu)(chu) 理(li)(li)。該(gai)零件(jian)的(de)工(gong)藝流程為(wei)(wei):正火→車削→銑齒→插(cha)鍵(jian)槽(cao)→滲碳(tan)淬火及退火→噴砂→防銹處(chu)(chu)(chu)理(li)(li)。工(gong)藝難點為(wei)(wei)銑齒和熱處(chu)(chu)(chu)理(li)(li)工(gong)序。
