在機械生產中是離不開銅套這個重要的連接物的，可以說，銅套是機械加工生產中的聯系者，今天合肥銅件加(jia)工就來告訴你銅套何時使用才好。

　　銅(tong)(tong)(tong)(tong)套應(ying)在(zai)熱處(chu)理后(hou)使用，因為(wei)銅(tong)(tong)(tong)(tong)的強度，尤其是(shi)塑性(xing)和(he)(he)韌性(xing)下降(jiang)。為(wei)細化晶粒、均勻組織(zhi)及消除內應(ying)力(li)，銅(tong)(tong)(tong)(tong)套必(bi)須(xu)進行正(zheng)(zheng)火(huo)(huo)(huo)或退(tui)火(huo)(huo)(huo)處(chu)理。正(zheng)(zheng)火(huo)(huo)(huo)處(chu)理后(hou)的銅(tong)(tong)(tong)(tong)，機器性(xing)能(neng)在(zai)退(tui)火(huo)(huo)(huo)后(hou)的高(gao)成本也變(bian)低，所以應(ying)用非常廣(guang)泛。但是(shi)，正(zheng)(zheng)火(huo)(huo)(huo)處(chu)理導(dao)致(zhi)比較退(tui)火(huo)(huo)(huo)大的內力(li)，只適用于(yu)碳含(han)量0.35%的銅(tong)(tong)(tong)(tong)件(jian)。低碳銅(tong)(tong)(tong)(tong)件(jian)可塑性(xing)好(hao)，冷卻時容易碎。內力(li)變(bian)小(xiao)，銅(tong)(tong)(tong)(tong)張(zhang)正(zheng)(zheng)火(huo)(huo)(huo)后(hou)，還應(ying)進行高(gao)溫回火(huo)(huo)(huo)。對碳含(han)量。0.35%的，復雜的結構和(he)(he)容易發生裂紋的銅(tong)(tong)(tong)(tong)件(jian)只能(neng)進行，退(tui)火(huo)(huo)(huo)處(chu)理。銅(tong)(tong)(tong)(tong)件(jian)不宜淬火(huo)(huo)(huo)，否則極易開裂。

　　銅(tong)套(tao)的(de)(de)工(gong)作原理：在(zai)中空軸(zhou)(zhou)含銅(tong)效果(guo)也被用來作為滑(hua)(hua)動(dong)軸(zhou)(zhou)承(cheng)，滑(hua)(hua)動(dong)旋轉(zhuan)工(gong)作軸(zhou)(zhou)在(zai)軸(zhou)(zhou)承(cheng)上的(de)(de)摩(mo)擦，潤(run)滑(hua)(hua)系統(tong)通常需要額外的(de)(de)工(gong)作。滑(hua)(hua)動(dong)軸(zhou)(zhou)承(cheng)工(gong)作平(ping)穩，可(ke)靠，無噪(zao)聲。在(zai)流體(ti)潤(run)滑(hua)(hua)條件下分(fen)離從(cong)滑(hua)(hua)動(dong)面不直(zhi)接與油接觸，但也可(ke)能(neng)大大降低摩(mo)擦和磨損的(de)(de)表(biao)面，該薄膜還具(ju)有振(zhen)動(dong)吸收能(neng)力。
