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)徑縮小；③同時(shí)加大外徑縮小內(nèi)徑。不管是哪種形式，管坯鐓粗時(shí)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(shí)踐經(jīng)驗(yàn)，人們總結(jié)出管坯局部鐓粗時(shí)應(yīng)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(dāng)管坯變形部分長度小于管坯壁厚的3倍時(shí)，允許一次鐓粗到任意外徑而不產(chǎn)生彎曲。2)當(dāng)管坯變形部分長度大于管坯壁厚的3倍時(shí)（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(dá)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。 </p><div
