可移動車載大跨度輥壓成型機之壓成型工(gong)藝介紹
壓成(cheng)(cheng)型(xing)工(gong)(gong)(gong)藝(yi)主要是(shi)靠材料的(de)(de)(de)塑性移動滾壓加工(gong)(gong)(gong)成(cheng)(cheng)各(ge)種形狀復(fu)雜(za)的(de)(de)(de)軸(zhou)桿、閥門芯(xin)和(he)特(te)殊緊固(gu)件(jian)等產(chan)(chan)品(pin)。滾壓變形是(shi)線接觸，連(lian)續逐(zhu)步地進(jin)行，所需變形力較小，一(yi)個行程可生產(chan)(chan)一(yi)個或幾個工(gong)(gong)(gong)件(jian)。滾壓成(cheng)(cheng)型(xing)工(gong)(gong)(gong)藝(yi)和(he)切削、磨削工(gong)(gong)(gong)藝(yi)相(xiang)比，它不僅生產(chan)(chan)效率高、節約材料，而且產(chan)(chan)品(pin)強度高、質量穩定，這(zhe)種工(gong)(gong)(gong)藝(yi)特(te)別適于加工(gong)(gong)(gong)的(de)(de)(de)特(te)長短(duan)難于切削的(de)(de)(de)工(gong)(gong)(gong)件(jian)，尤其對年產(chan)(chan)上百萬件(jian)大批量的(de)(de)(de)產(chan)(chan)品(pin)，采(cai)用滾壓成(cheng)(cheng)型(xing)工(gong)(gong)(gong)藝(yi)最為(wei)有(you)利，經濟效益也最為(wei)可觀(guan)。
