扭纹机，也就扭拧机、麻花机，是将金属棒材或管材进行扭曲的专业设备。一般扭曲的纹路多为麻花状。
Twisting machine, also twist machine, twist machine, is the metal bar or pipe to twist the professional equipment. The general twisted lines are mostly twist-like.

扭纹机工作原理/Working principle of twisting machine：
扭纹前先将管材或棒材穿过扭转卡口，工件一端固定在移动滑块上，如果是管材，需要在管材内部填充沙土，以防管材扭曲过程中出现爆裂情况，然后开动设备，卡口旋转，带动工件被动旋转，从而形成麻花纹。
Before the twist, the pipe or bar through the torsion bayonet, the workpiece at one end fixed on the moving slider, if it is pipe, the need to fill the sand inside the pipe to prevent the process of breaking the pipe twist, and then start the device, Mouth rotation, driving the workpiece passive rotation, thus forming hemp pattern.
