20px;">佩戴的芯棒在彎曲過(guò)程中主要起著支撐導(dǎo)管彎曲半徑的內(nèi)壁阻止其變形的作用。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)鋼管彎曲成形也有影響：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，提前1～2mm較好，此時(shí)彎管質(zhì)量比較理想。當(dāng)然，提前量太大，會(huì)造成彎曲部分的外壁出現(xiàn)不均勻現(xiàn)象。</span></div> <div> <span style="font-size:20px;">彎管機(jī)設(shè)計(jì)和排管時(shí)要避免過(guò)大的圓弧、任意曲線、復(fù)合彎以及大于180°的圓弧。過(guò)大的圓弧不但使工裝笨重，而且受彎管機(jī)機(jī)床尺寸的限制；任意曲線、復(fù)合彎設(shè)計(jì)造型很不合理，有的妨礙了機(jī)械化、自動(dòng)化生產(chǎn)，使操作者難以擺脫笨重的體力勞動(dòng)；大于180°的圓弧使彎管機(jī)無(wú)法卸模。</span></div> <div> <span style="font-size:20px;"><a href="http://www.349you.cn">彎管機(jī)</a>的彎曲半徑要盡量實(shí)現(xiàn)“一管一模”和“多管一模”。對(duì)于一根管子來(lái)說(shuō)，無(wú)論有幾個(gè)彎，彎曲角度如何，其彎曲半徑只能有一個(gè)，因?yàn)閺澒軝C(jī)在彎曲過(guò)程中不換模塊，這就是“一管一模”。而“多管一模”，就是同一直徑規(guī)格的管子應(yīng)盡量采用同一種彎曲半徑，也就是使用同一套模塊彎制不同形狀的管形，這樣才有利于減少模塊數(shù)量。</span></div> <div> <span style="font-size:20px;">彎管彎曲半徑的大小，決定了鋼管在彎曲成形時(shí)所受阻力的大小。一般來(lái)說(shuō)，管徑大彎曲半徑小，彎曲時(shí)容易出現(xiàn)內(nèi)皺和打滑現(xiàn)象，彎曲質(zhì)量很難保證，所以一般選用彎管模的R值為管子直徑的2-3倍為好。</span></div> <div> <span style="font-size:20px;">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鋼管彎曲部分的下陷。針對(duì)這兩臺(tái)彎管機(jī)上大量的試驗(yàn)，將鋼管的彎曲速度確定為機(jī)器大彎曲速度的20%-40%為宜。</span></div>
