四、不对稱式三滾筒彎捲机 (1)工作概述不对称的三滾筒式与对称三滾筒式的區別,是在於中間的滾筒在兩側滾筒的前方,这样就大大地減少了剩餘不能弯曲的部份,而可以計算它們的实际弯曲。桿件的剩餘的直的部份,必須要在其他机械中或手工加以弯曲,增加了很多的麻煩。因此,这个型式的弯捲机可使產品沿整个長度弯曲,这就是它的优點。弯曲桿件的弯曲半徑是靠後滾筒的位置調整得到的。 傳動滾筒一般是設計在中部,但有時也有兩面可以传动的——中部的及前面的(参看图二6)。
Fourth, the asymmetric three-roll coiling machine (1) Overview of work asymmetric three-cylinder and symmetrical three-cylinder type of difference is that the middle of the drum in front of both sides of the drum, thus greatly reducing the remaining can not be bent And you can calculate their actual bending. The remaining straight part of the bar must be bent in other machines or manually, adding a lot of hassle. Therefore, this type of curling machine can make the product bend along the entire length, and this is its advantage. The bending radius of the bending member is adjusted by the position of the rear drum. The drive drum is usually designed in the middle, but sometimes there are two sides can drive - the middle and the front (see Figure 2.6).
