自主开发的拉弯式液压成排弯管机具有结构简单、可靠，可弯管屏形状复杂，还可校正管屏、造价低廉等特点。
Hydraulic type row tube bender is simple in structure, reliable which can bend and correct complicated platen with low cost.
这种弯管机由钢制机架、下模、上模、夹具、液压系统和内胎等组成，其工作原理是通过确定合理的支点和受力点并施加弯曲力矩，使钢管发生塑性变形，实现钢管的冷弯曲。
By determining rational fulcrum and force bearing point, and applying bending torque to cause the plastic deformation of the steel pipe, it can realize the cool bending of the pipe.
在摩托车车架等构件中，立体转角管状零件各圆弧均不共面，在普通弯管机上没有空间转角功能；
The arcs of tubular parts with stereo turning angles are not coplanar. Ordinary bending machine can not bend a space turning angle.
