Then, the first bidirectional threaded rod 13 is rotated to make the roller 7 clamp the wing plates of the H-shaped steel, and then the H-shaped steel is conveyed by the transmission roller 1, which will cause the roller 7 to rotate at the same time. During the transportation of the H-shaped steel, the wing plates of the H-shaped steel are clamped by the roller 7, thereby preventing the wing plates of the H-shaped steel from bending and improving the stability of the H-shaped steel correction.

[0024] In the present utility model, the power component is a two-way cylinder 6, which is fixed in the slide 5 by bolts. The two-way cylinder 6 is located between the two slides 3, and the output shafts at both ends of the two-way cylinder 6 are respectively fixed to the two slides 3.

A rolling groove is opened on one side of multiple rollers 7, and a ball 8 is connected to the rolling groove. The ball 8 can roll when the H-shaped steel is conveyed, thereby reducing the friction between the roller 7 and the H-shaped steel. A baffle 14 is welded to one end of each of the multiple first guide rods 12 and the multiple second guide rods 15.

[0026] Working principle: When it is needed, the H-shaped steel is placed on the transmission roller 1, and then the second bidirectional threaded rod 16 is rotated.
