The front roller body and the rear roller body are connected and fixed together to form a complete upper forming roller. The structure of the upper left forming roller and the upper right forming roller are the same as those of the middle forming roller. same.

The utility model has the advantages that: when the motor reducer works, the left and right gears drive the left lower forming roller and the right lower forming roller to rotate, the steel belt enters from between the left lower forming roller and the left upper forming roller, Between the forming rollers, due to the middle upper forming roller, the height between the middle upper forming roller and the base is smaller than the height between the left and right forming rollers and the base, and the front roller body of the left and right lower forming rollers is from the front to the front. Then it gradually becomes thinner, and the front roller body of the upper forming roller gradually becomes thicker from front to back, so the steel belt can be pressed out of the inclined surface when it is bent, and the processed inclined surface is smooth and flat, which will not scratch the steel pipe, and is easy to install and disassemble . In addition, because the upper forming roll hanger is installed on the frame through the adjusting screw, the distance between the upper forming roll and the lower forming roll can be adjusted according to the thickness of the steel strip. Since several upper forming roller mounting holes are arranged on the upper forming roller hanger, the installation positions of the three upper forming rollers can be adjusted according to the specifications of the steel strip.
