[0023] Turn the second screw rod to push the second straightening wheel downward, press the steel pipe onto the transmission concave core wheel, turn the first screw rod to push the first straightening wheel to clamp the steel pipe, and then clamp and straighten it. Figure 1-4 As shown, the umbilical cable steel pipe straightening device described in the present invention includes a base 1, a transmission concave core wheel 4 and a large gear 7. The second straightening components 3 are provided at both ends of the top of the base 1. The second straightening components 3 include side plates 301 fixed to the two ends of the top of the base 1 by bolts. A second screw rod 302 is sleeved through the top of the side plate 301 through a threaded groove. The bottom end of the second screw rod 302 is connected to a second structural frame 303 through a bearing. The second structural frame 303 is rotatably connected to a second straightening wheel 304 through a shaft.

[0024] A first straightening assembly 2 is provided on both sides of the base 1. The first straightening assembly 2 includes an L-shaped side plate 201 fixed to both sides of the base 1 by bolts. One side of the L-shaped side plate 201 is connected to a first screw rod 202 through a threaded groove. One end of the first screw rod 202 located at the top of the base 1 is connected to a first structural frame 203 through a bearing. One side of the first structural frame 203 is rotatably connected to a first straightening wheel 204 through an axis rod.

[0025] During use, the second screw 302 is rotated to push the second straightening wheel 304 downward to press the steel pipe onto the transmission concave core wheel 4, and the first screw 202 is rotated to push the first straightening wheel 204 to clamp the steel pipe. The servo motor 6 drives the transmission concave core wheel 4 to rotate, pushes the steel pipe to move, and straightens the steel pipe.

[0026] For example, Figure 2 As shown, the present invention also includes that the two ends of the top of the base 1 are rotatably connected to the transmission concave core wheels 4 through a shaft, and the top of the base 1 located between the transmission concave core wheels 4 is rotatably connected to the auxiliary concave core wheel 5 through a shaft.

[0027] When in use, a plurality of auxiliary concave core wheels 5 are used to assist the movement of the steel pipe.

[0028] For example, Figure 2 As shown, the present invention further comprises: servo motors 6 are mounted on both ends of the base 1 through mounting brackets; a large gear 7 is fixed on an output shaft on one side of the servo motor 6 through a flat key fixing sleeve.
