[0022] The utility model embodiment discloses a steel pipe straightening device.

[0023] Reference Figure 1-Figure 3A steel pipe straightening device includes a support base plate 11, a U-shaped steel bar 1 and a support member 7 are arranged on the support base plate 11, the U-shaped steel bar 1 has a U-shaped groove, a roller 6 is arranged on the support member 7, a limiting portion 5 is arranged on the support member 7, the limiting portion 5 is used to limit the lateral displacement of the steel pipe, and the steel pipe passes through the limiting portion 5 through the roller 6 and is inserted into the U-shaped groove. The bent steel pipe is rotated by the roller 6, adjusted and fixed by the limiting portion 5, and then enters the U-shaped groove of the U-shaped steel bar 1. A person applies a downward force to the bent steel pipe, and the steel pipe uses the roller 6 as a fulcrum, and is fixed by the limiting portion 5, so that the bent steel pipe is corrected.

[0024] The longitudinal section of the U-shaped steel bar 1 is U-shaped, and the U-shaped steel bar has a U-shaped groove, and the U-shaped groove is located at the top for contacting with the steel bar.

[0025] The length direction of the support bottom plate 11 is adjustable. The support bottom plate 11 includes a support outer plate and a support inner plate. The U-shaped steel bar 1 and the support member 7 are respectively arranged on the support outer plate and the support inner plate. By moving the support inner plate to adjust the spacing between the U-shaped steel bar 1 and the support member 7, the purpose of straightening steel bars of different lengths is achieved, thereby improving applicability. Bolts 2 or latches are used to fix the length of the support bottom plate 11, which is a prior art and will not be described in detail here.

[0026] The roller 6 is mounted on the support member 7 via a mounting frame, and the roller makes it easier for the steel pipe to be inserted into the U-shaped steel bar through the limiting portion.

[0027] The height of the support member 7 is adjustable. The support member 7 includes an inner tube and an outer tube.
