style="text-indent:25px">彎曲成形速度對(duì)成形質(zhì)量的主要影響為：速度太快，容易造成導(dǎo)管彎曲部分的扁平，圓度達(dá)不到要求，造成導(dǎo)管的拉裂、拉斷；速度太慢，容易造成導(dǎo)管的起皺和壓緊塊打滑，大管徑的管子易形成導(dǎo)管彎曲部分的下陷。針對(duì)這兩臺(tái)數(shù)控彎管機(jī)上大量的試驗(yàn)，將導(dǎo)管的彎曲速度確定為機(jī)器較大彎曲速度的20%-40%為宜。芯棒在彎曲過(guò)程中主要起著支撐導(dǎo)管彎曲半徑的內(nèi)壁防止其變形的作用。國(guó)產(chǎn)管材在機(jī)床上彎曲成形若不使用芯棒，其質(zhì)量難以保證。芯棒的形式有很多種，如柱式芯棒，萬(wàn)向單、雙、三、四球頭芯棒，定向單、多球頭芯棒等。另外，芯棒的位置對(duì)導(dǎo)管彎曲成形也有一定的影響：理論上，它的切線應(yīng)與彎管模的切線平齊，但經(jīng)過(guò)大量的試驗(yàn)證明，六安彎管機(jī)有哪些，提前1～2mm較好，六安彎管機(jī)有哪些，此時(shí)彎管質(zhì)量比較理想。當(dāng)然，六安彎管機(jī)有哪些，提前量太大，會(huì)造成彎曲部分的外壁出現(xiàn)所謂“鵝頭”的現(xiàn)象。雙頭彎管機(jī)有轉(zhuǎn)角于不轉(zhuǎn)角區(qū)別。六安彎管機(jī)有哪些</p><div
