The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] For embodiments, please refer to Figures 1-3 This utility model provides a technical solution:

[0023] A rail steel straightening roller includes a left roller shaft 1 and a right roller shaft 2. Axial limit rings 3 are fixedly sleeved on the outer sides of the left roller shaft 1 and the right roller shaft 2 and at opposite ends. Flange plates 4 are connected to the ends of the left roller shaft 1 and the right roller shaft 2 facing each other. Waist-shaped through grooves 5 extending along the length direction are opened inside the left roller shaft 1 and the right roller shaft 2. Adjusting screws 6 are rotatably connected inside the left roller shaft 1 and the right roller shaft 2. One ends of the two groups of adjusting screws 6 passing through the left roller shaft 1 and the right roller shaft 2 are respectively threadedly sleeved with locking nuts 601. A screw sleeve 602 is threadedly sleeved on the outer side of the adjusting screw 6. Clamping retainers 7 are slidably sleeved on the outer sides of the left roller shaft 1 and the right roller shaft 2. Rotate the adjusting screw 6 so that the adjusting screw 6 rotates and threads to drive the screw sleeve 602 to move inward until the two groups of clamping retainers 7 clamp and fix the straightening roller wheels 8. Then, fix the adjusting screw 6 through the locking nut 601. Multiple groups of closely distributed straightening roller wheels 8 are sleeved on the outer sides of the left roller shaft 1 and the right roller shaft 2 and inside the clamping retainers 7. When straightening I-shaped rail steels with different web width dimensions, the number of straightening roller wheels 8 can be adjusted for adaptation;

[0024] Wherein, the two groups of flange plates 4 are connected by bolts. The left roller shaft 1 and the right roller shaft 2 are designed as a detachable structure. The two ends of the two groups of adjusting screws 6 are respectively rotatably connected inside the left roller shaft 1 and the right roller shaft 2 through bearing seats. One ends of the two groups of adjusting screws 6 passing through the left roller shaft 1 and the right roller shaft 2 are both connected with manual adjustment caps. The upper and lower ends of the screw sleeve 602 are fixedly connected to the inner walls of the clamping retainers 7. The straightening roller wheels 8 and the left roller shaft 1 and the right roller shaft 2 are designed as detachable structures.

[0025] The working process of the utility model: Connect the whole roller shaft to the straightening machine respectively, and straighten the I-shaped rail steel through the straightening roller 8. However, when encountering I-shaped rail steels with different web width dimensions, the number of straightening rollers 8 can be adjusted for adaptation. The specific operation is to remove the whole roller shaft and split it into the left roller shaft 1 and the right roller shaft 2 through the flange 4. Then, several straightening rollers 8 are sleeved on the left roller shaft 1 and the right roller shaft 2 until they are adapted to the web width dimension. Then, connect the flange 4, and then rotate the adjusting screw 6 respectively, so that the rotation thread of the adjusting screw 6 drives the screw sliding sleeve 602 to move inward until the two groups of clamping flanges 7 clamp and fix the straightening roller 8. Then, fix the adjusting screw 6 through the locking nut 601, change the originally fixed straightening roller structure into an adjustable structure, and realize the universality of a set of straightening rollers among I-shaped rail steel products of various specifications.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
