卷板機的運動方式如何選擇?

    卷板機在運行的時候會做主要的運動和輔助的運動,主要的運動一般由卷板機工作輥的上下錕運動完成,這種運動包括旋轉及彎折等,這種主運動可以幫助卷板機來完成對板材的加工。輔助的運動包括在加工的過程中,對設備進行裝料和下料等操作,還包括上輥進行升降的操作,翹起的操作,倒頭架進行翻轉等不同形式運動的操作。
    對板材進行加工的過程包括有卷板,彎曲,折邊及模具的壓制等環節,其中卷板是第一個環節,這個環節也有的稱為滾圓,就是讓板材經受外力作用,達到外層的纖維發生伸長,內層的纖維發生縮短,而板材中層的纖維并不會發生任何的變化。這樣板材就會產生一種彎曲的變形情況,從而能夠形成圓筒等形狀,卷板機的工作原理便是如此了。
    在筒形半徑比較大的情況下,多數會用機械的方式來進行卷板操作,卷板機就是進行這項操作的設備,當然也可以選擇胎膜的壓制或者是人工的卷板操作,但是從效率上來說,使用卷板機來做卷板操作,其工作的效率是最高的。而當筒形半徑比較小的情況下,可以先對板材加熱后,板材在受熱后其纖維改變會更容易,然后再進行卷板操作。
