Its background technology involves knowledge and technology in multiple fields. During the construction process of high-speed rail lines, they need to pass through various complex terrains and landforms. In order to adapt to the changes in these terrains and landforms, high-speed rail pipe fittings need to be stretched and bent to achieve the bending and deformation of the pipe fittings, thereby meeting the curve requirements of the line.

[0003] In the prior art, high-speed rail reducers usually use a bending machine to apply bending force inside the pipe, so that the pipe is bent on a bending die with a certain radius, thereby obtaining the desired reducer shape. However, after the traditional pipe bending machine completes the bending of the pipe, the pipe is stuck during the removal process due to deformation, which increases the difficulty of removing the pipe from the bending machine and reduces work efficiency.

[0023] The effect achieved by the entire embodiment 1 is as follows: when using the device to stretch and bend the high-speed railway reducer, first turn on the driving motor 301 on the mounting shell 1, and use its output end to drive the threaded screw 302 to rotate. When the threaded screw 302 rotates, its spiral thread will push the slide rail 304 to move in the axial direction, so that the slide rail 304 moves parallel to the chassis 303, and because of the movement of the slide rail 304, the first pulley 306 and the second clamping block 307 will follow the movement through the sliding groove 21.
