[0004] However, the current guide device is not stable as a whole due to the use of two open guide wheels. The shaking of the rolled piece causes torsion and rib formation, which affects product quality. Utility Model Content

[0005] In order to overcome the defects of the prior art that the rolling piece shakes and causes torsion and rib formation, the utility model provides a crescent rib anchor rod guide device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a crescent rib anchor rod guide device, including a base and a rotating gear ring, the base is provided with a left gear group and a right gear group, the rotating gear ring is meshed with the left gear group and the right gear group, a plurality of positioning cylinders are provided on the inner ring surface of the rotating gear ring, each positioning cylinder points to the center of the rotating gear ring, and a guide stick is provided at the output end of each positioning cylinder.

[0007] As a further improvement of the present invention, the left gear set and the right gear set are symmetrically arranged.

[0008] As a further improvement of the present invention, the left gear set and the right gear set both include a bearing seat and a load-bearing gear disposed on the bearing seat.

[0009] As a further improvement of the present invention, the right gear set is connected to the servo motor via a speed reducer.

[0010] As a further improvement of the utility model, the positioning cylinder is a hydraulic telescopic cylinder.

[0011] As a further improvement of the utility model, there are at least four positioning cylinders, and each positioning cylinder is equidistantly distributed on the inner ring surface of the rotating gear ring.

[0012] Compared with the prior art, the utility model has the following beneficial effects: In this solution, a plurality of positioning cylinders are arranged on the inner ring surface of the rotating gear ring, each positioning cylinder points to the center of the rotating gear ring, and a guide rod is arranged at the output end of each positioning cylinder. The rolled piece is fixed by the guide rod at the end of the positioning cylinder, and the rotating gear ring rotates, so that the guide rod at the end of the positioning cylinder rotates closely around the rolled piece, which improves the stability and adjustment accuracy, and solves the problem of torsion and rib deformation caused by the shaking of the rolled piece.
