1.彎管成型過程中光滑對產(chǎn)品質(zhì)量的影響：企業(yè)在傳統(tǒng)的彎管生產(chǎn)工藝中，為得到更好的彎管表面質(zhì)量，會采納許多的辦法，其中包括：采用更先進(jìn)高（gao）擋的彎管機(jī)，用強(qiáng)度更高的模具，或者采用光滑產(chǎn)品等辦法。 2.彎管時(shí)資料外側(cè)受拉，內(nèi)側(cè)受壓中性軸所在位置則與彎管辦法而不同，在頂彎式(壓縮彎曲)作業(yè)時(shí)中性軸處于離外壁約1/2處，在旋彎(回彎式)作業(yè)時(shí)，中性軸處于離外壁2/2處。因此薄壁管道彎曲，使用旋彎法是有利的。。黑龍江彎管制造</p><div style="width:100%;text-align: center;"><img
