(3)端面不平的管坯，不能鐓粗成形在生產(chǎn)條件下，管料可以通過高速帶鋸鋸切或利用模具剪切，管坯端面可能既不平整，也不與軸線垂直，這時施加軸壓壓力必然導致軸壓失穩(wěn)，因此端面不平的管坯，不能進行鐓粗成形。 </p> <p> (4)法蘭高度小于管坯壁厚的1/2時，一次鐓粗的法蘭外徑不能超過管坯外徑的2.5倍當法蘭高度小于管坯厚度的1/2時，一次鐓粗的法蘭外徑不能超過管坯外徑的2.5倍，否則將引起管坯失穩(wěn)而導致外壁折疊。 </p><p

近年來，隨著車輛輕量化發(fā)展要求，局部加厚管這類零件需求量也增大，因此管坯鐓壓成形工藝得到發(fā)展。管坯局部鐓粗的零件有以下幾種形式：①管子內(nèi)徑保持不變、外徑加大而加粗管坯；②管子外徑保持不變而內(nèi)徑縮?。虎弁瑫r加大外徑縮小內(nèi)徑。不管是哪種形式，管坯鐓粗時的主要問題是防止管壁因縱向彎曲所引起的折紋。通過長期生產(chǎn)實踐經(jīng)驗，人們總結出管坯局部鐓粗時應遵循的工藝原則，即所謂的管坯局部鐓粗規(guī)則。 </p> <p> 概括起來，主要有兩條：1)當管坯變形部分長度小于管坯壁厚的3倍時，允許一次鐓粗到任意外徑而不產(chǎn)生彎曲。2)當管坯變形部分長度大于管坯壁厚的3倍時（一般是這種鐓粗），必須在模具中鐓粗，且一次局部鐓粗所能達到的比較大厚度不能超過原始管坯厚度的1.5倍，否則將產(chǎn)生失穩(wěn)變形。湖南鋼管生產(chǎn)廠家</p><p
