弯管器的使用
Using the bender
使用弯管器
swing the short handle up so it is above the bender die.
旋转起短臂使得它在弯管器钢槽上方
Open roll support.
从连接叉松下短臂，在卷支撑没有移动的情况下，直到短臂摇动。
swing the short handle up until it is slightly above perpendicular to the long handle.
摇起短臂直到些微垂直与长臂。
Retighten the short handle. this will provide continuous right-angle leverage for the rest of the bend.
紧上短臂，这将保证直角杠杆继续于弯曲的剩余部分。
Continue the bend until the 0 on the roll support reaches the desired degree mark on the name plate.
继续弯曲，直到在卷支撑的0刻度到达要求的角度的角度盘面处。
After completing the bend, swing the short handle away ,pausing when the 0 on the roll support reaches approximately 90°.loosen the short handle, move it until parallel with the long handle, then retighten the short handle.
完成弯曲后，松动短臂离开，当在卷支撑处的0刻度到达大约90度时暂停。松开短臂，调整它直到平行于长臂，然后重新紧上。
Move the short handle up and away from the tube.
提起短臂，离开管。
Pull the tube latch off the tube and remove the tube from the bender groove.
解开管的锁刃，把管从弯管器凹槽移开。
Reverse bends
反向弯曲
The measure-bend method
弯曲的方法
Sometimes a multiple bend layout will require that a bend be made in reverse. A reverse bend is made with the reference mark to the right of tube latch.
有时候一个多重弯曲的布局将需要反向弯曲，一个反向弯曲是指参考标记在锁刃的右边。
Align the bend mark with the marks on the roll support as follows:
配合在卷支撑上的标记与弯曲标记如下方式：
90°bends line up under the R mark
90度弯曲标记线在R标记下方
For other bend angles, treat the marks between 0 and R as an approximate 0 to 90 scale.
对于其他角度，以大约在0到90度的比例大约对应于0到R的比例。
bend the tube as described in making bends, page 15.
弯管的介绍在15页。
Springback
弹性回弹
All tubing will exhibit springback after a bend has been completed. The amount of springback depends on the bend angle, bend radius, tubing material, and wall thickness.
在弯曲已经完成后，所有管线都会产生弹性回弹。弹性回弹的程度取决于弯曲的角度，弯曲半径，管的材质，和管壁厚度。
Experience will help you predict the amount of springback. Expect to allow 1 to 3° of compensation.
经验将帮助你预测弹性回弹的程度。认为可以有允许1至3度的补偿。
Note: verify the bend angle using a template, pro
