The sliding sleeve 26 is fixedly connected to one side of the supporting leg 3, the sliding rod 27 is slidably connected to the inside of the sliding sleeve 26, the movable frame 28 is fixedly connected to the top of the sliding sleeve 26, the rack 29 is fixedly connected to the inner walls of the left and right sides of the movable frame 28, and the movable frame 28 is fixedly connected to the trapezoidal top block 24 through a connecting rod. The sliding sleeve 26 is provided to limit the movement of the sliding rod 27. The motor 211 is fixedly connected to the front of the supporting leg 3, and the rear output end of the motor 211 passes through the front and rear ends of the supporting leg 3 and is fixedly connected to the front of the half-toothed gear 210, and the half-toothed gear 210 is meshed with the rack 29.

[0025] Specifically, the motor 211 drives the half-toothed gear 210 to rotate, and the rotation of the half-toothed gear 210 drives the trapezoidal top block 24 to reciprocate up and down, and pushes a steel pipe onto the processing platform 1.

[0026] Embodiment 2

[0027] like Figure 1-4 As shown, a conveying mechanism 4 is provided on the left side of the processing platform 1. The conveying mechanism 4 includes a transverse shaft 41. There are two transverse shafts 41. The front and rear ends of the two transverse shafts 41 are rotatably connected to the support legs 3 through bearings. The support legs 3 are provided to provide support force for the transverse shaft 41. The half-toothed gear 210 is fixedly connected to the right transverse shaft 41. A roller 42 is fixedly connected to the middle of the transverse shaft 41. A transmission belt 43 is provided on the outer sleeve of the two rollers 42.

[0028] Specifically, the rotation of the half-toothed gear 210 drives the right horizontal shaft 41 to rotate, and the rotation of the right horizontal shaft 41 drives the transmission belt 43 to rotate, and the steel pipe is transported.

[0029] The working principle of the utility model is as follows:

[0030] First, multiple steel pipes are placed at the upper left corner of the transmission belt 43, and then the motor 211 is turned on to drive the half-toothed gear 210 to rotate. The rotation of the half-toothed gear 210 drives the right horizontal shaft 41 to rotate, and the rotation of the right horizontal shaft 41 drives the right turntable 44 to rotate.

The half-toothed gear 210 rotates through the rack 29 to drive the movable frame 28 to move up and down reciprocatingly. The movable frame 28 moves up and down reciprocatingly and drives the trapezoidal top block 24 to move up and down reciprocatingly through the connecting rod. When the trapezoidal top block 24 moves downward, the first steel pipe on the right side will roll to the top of the trapezoidal top block 24 under the push of the subsequent steel pipes, and in the process of the trapezoidal top block 24 moving upward, it will be lifted up by the trapezoidal top block 24, and after contacting the trapezoidal fixed block 22, it will roll down along its inclined surface to the lower right corner, and roll onto the processing platform 1. If the device is needed to feed the pipe bender, the pipe bender can be moved to the position of the processing platform 1.
