【勞動模范】夏天堯——不空談，講實干，用心造好國產裝備

夏天堯(yao)作為(wei)重慶(qing)通(tong)用工(gong)(gong)業(ye)（集團(tuan)）有限責任公司(si)加工(gong)(gong)車間數(shu)控車工(gong)(gong)、高級技師、質量放心員工(gong)(gong)，曾先(xian)后(hou)榮(rong)獲(huo)“重慶(qing)市(shi)五(wu)一勞(lao)動(dong)獎章”“重慶(qing)市(shi)勞(lao)動(dong)模范”等榮(rong)譽。

毫厘之間方顯本色

作為高端裝備的(de)制造企(qi)業，產(chan)品(pin)(pin)零部(bu)件(jian)種類繁多，加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)要(yao)(yao)求(qiu)極高，沒有(you)過硬的(de)技(ji)(ji)術(shu)根本無法勝任(ren)關鍵零部(bu)件(jian)的(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)任(ren)務(wu)。夏天堯主要(yao)(yao)從(cong)事大型壓縮(suo)機、船用(yong)、核(he)電等重(zhong)點產(chan)品(pin)(pin)的(de)零部(bu)件(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)。其中(zhong)大型離心式(shi)壓縮(suo)機屬(shu)于(yu)國(guo)(guo)家重(zhong)大裝備，因(yin)其工(gong)(gong)(gong)藝(yi)(yi)技(ji)(ji)術(shu)要(yao)(yao)求(qiu)極高，在(zai)全國(guo)(guo)只有(you)少(shao)數幾個單位具(ju)有(you)實力生產(chan)；船用(yong)、核(he)電用(yong)大型離心式(shi)冷水機組，使用(yong)工(gong)(gong)(gong)況復雜，核(he)心零部(bu)件(jian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)要(yao)(yao)求(qiu)極為嚴苛。近年來，他在(zai)承擔(dan)這些產(chan)品(pin)(pin)核(he)心零部(bu)件(jian)的(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)攻(gong)關任(ren)務(wu)中(zhong)，從(cong)識(shi)圖到(dao)刀具(ju)、切削要(yao)(yao)素(su)、加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)路線的(de)選擇，再到(dao)編制加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)程序，歸納總結了一整套具(ju)有(you)創新(xin)性(xing)、針對性(xing)、可操(cao)作性(xing)的(de)四步加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)法，使得(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)周期(qi)縮(suo)減20%且一次性(xing)質量合格率(lv)100%。

千鈞之壓助力國防

公(gong)(gong)司在初次接受到某型產(chan)品的(de)加(jia)(jia)(jia)工(gong)(gong)時，發(fa)現其(qi)中關鍵部件(jian)(jian)是在內孔加(jia)(jia)(jia)工(gong)(gong)M65×36（P1.5）多(duo)頭(tou)螺(luo)紋(wen)。公(gong)(gong)司由于多(duo)頭(tou)螺(luo)紋(wen)的(de)零(ling)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)少，最(zui)多(duo)也(ye)就2-3頭(tou)螺(luo)紋(wen)，這種24頭(tou)螺(luo)紋(wen)公(gong)(gong)司從來沒有(you)人做過。夏天(tian)堯了(le)解情況(kuang)后(hou)，主動請纓，通過對(dui)多(duo)頭(tou)螺(luo)紋(wen)外協零(ling)件(jian)(jian)圖(tu)紙的(de)消化，根據豐富的(de)加(jia)(jia)(jia)工(gong)(gong)經驗，決定選(xuan)擇合(he)理的(de)車削參數，用(yong)自制修磨的(de)螺(luo)紋(wen)車刀(dao)，選(xuan)擇合(he)理的(de)前(qian)角、后(hou)角和副后(hou)角等(deng)方法，采用(yong)淺(qian)刀(dao)快走(zou)多(duo)循環的(de)加(jia)(jia)(jia)工(gong)(gong)方式，并且自制檢(jian)(jian)驗量(liang)具進行(xing)檢(jian)(jian)測，最(zui)終順利完(wan)成此次加(jia)(jia)(jia)工(gong)(gong)任務，為公(gong)(gong)司積累了(le)加(jia)(jia)(jia)工(gong)(gong)該類產(chan)品的(de)經驗。

埋頭鉆研屢破難關

公司新(xin)產品JFJ001型離心風機的(de)(de)進(jin)風口(kou)，其壁厚只(zhi)有2mm，屬于(yu)典型的(de)(de)異(yi)形薄壁件(jian)。夏天堯嘗試數十次不同的(de)(de)加(jia)(jia)工(gong)(gong)方法，通過上百次修磨修改自制刀具(ju)的(de)(de)參數，自制十多種(zhong)不同類型的(de)(de)工(gong)(gong)裝(zhuang)，最終創新(xin)自制一種(zhong)靠摩(mo)擦(ca)力帶動異(yi)形薄壁零件(jian)的(de)(de)車削工(gong)(gong)具(ju)來完成加(jia)(jia)工(gong)(gong)。順利(li)地(di)攻克此難題，為(wei)公司新(xin)產品開發(fa)奠定了堅實基礎。

2020年，公司接到某海上平臺壓縮機維修訂單后，經實地勘察發現，維修最大的困難在于壓縮機核心零部件葉輪的測繪制作。同時，該葉輪材質特殊、硬度極高、加工難度大等一系列難題擺在他面前。對此，他自行(xing)設計制作了一套(tao)內(nei)嵌套(tao)式(shi)裝夾工裝，既(ji)保證不(bu)傷(shang)密(mi)封齒又不(bu)傷(shang)整體(ti)型(xing)線，順利實現該型(xing)壓(ya)縮機葉輪(lun)的加(jia)工，為下(xia)一步國產化(hua)積累了豐(feng)富的加(jia)工經(jing)驗(yan)。
