A movable seat is fixedly installed on the top of the sliding rod 201. The internal rotation of the movable seat is connected to a rotating rod. A bending plate 202 is fixedly installed on one end of the rotating rod. A sliding plate 203 is fixedly installed on the bottom of the plurality of sliding rods 201. The internal thread of the sliding plate 203 is connected to a first screw rod 204. A first motor 205 is fixedly installed on the lower surface of the work table 1 through a shell. The output end of the first motor 205 is fixedly installed with a first screw rod 204. The lower surface of the first screw rod 204 is rotatably connected to a stabilizing frame. The outer surface of the stabilizing frame is slidably connected to the sliding plate 203.

[0029] The staff placed several steel pipe chairs inside the limit seat 3, and several steel pipe chairs passed through the inside of the bending plate 202, and then started the first motor 205 to drive the first screw rod 204 to rotate. The first screw rod 204 rotated on the surface of the stabilizing frame. As the first screw rod 204 rotated, the sliding plate 203 moved upward, and the sliding plate 203 drove the sliding rod 201 on the upper surface to move. The movement of the sliding rod 201 drove the top bending plate 202 to move through the movable seat and the internal rotating rod. The internal steel pipe chair was bent with the lower side of the guide roller 208 through the moving bending plate 202. The bending angle of the steel pipe chair can be controlled by the upward sliding bending plate 202, which improves the control accuracy of the device on the bending angle.
