Place the steel bar on the tops of the placement table 1 and the bending table 2. One side of the steel bar contacts the limit seat 4, and the other side of the steel bar extends into the groove inside the disc 3. Then start the motor 12, so that the motor 12 drives the large gear 13 to rotate. The small gear 15 meshes with the large gear 13, so that the motor 12 can drive the small gear 15 and the connecting rod 14 to rotate. And the sliding rod 6 is fixed to the outside of the connecting rod 14. Therefore, when the motor is started, the sliding rod 6 will slide inside the circular slideway 5, and the connecting rod 14 drives the bending disc 9 to move. During the movement of the bending disc 9, it contacts the steel bar. Through the movement of the bending disc 9, the steel bar can be bent. When it is necessary to adjust the bending angle, move the slider 8, so that the bending disc 9 slides inside the slide rail 7 through the slider 8. Thus, the distance between the bending disc 9 and the disc 3 can be adjusted. When the distance between the bending disc 9 and the disc 3 increases, the bending amplitude of the steel bar will become larger. Similarly, when the distance between the bending disc 9 and the disc 3 shortens, the bending amplitude of the steel bar will become smaller. Therefore, this device can adjust the bending amplitude of the steel bar. Twist the locking ring 11. The locking ring 11 displaces on the outside of the locking shaft 10.

The sliding rod 6 is hinged to one end of the push rod 16 through the hinge 17. When the motor 12 drives the sliding rod 6 to rotate, the push rod 16 is driven by the cylinder 24 to displace the sliding rod 6, thereby reducing the load of the motor 12. And the sliding rod 6 and the push rod 16 are hinged through the hinge 17. Therefore, the sliding rod 6 can perform an arc-shaped movement. The outside of the cylinder 24 is fixedly connected to a cylinder bracket 18.

The support feet support the placing table 1 and the bending table 2, enabling the placing table 1 and the bending table 2 to be supported on the ground.

[0038] In this utility model, the steel bar is placed on the tops of the placing table 1 and the bending table 2. One side of the steel bar contacts the limit seat 4, and the other side of the steel bar extends into the groove inside the disc 3.

When the distance between the bending disc 9 and the disc 3 increases, the bending amplitude of the steel bar will become larger. Similarly, when the distance between the bending disc 9 and the disc 3 decreases, the bending amplitude of the steel bar will become smaller. Therefore, this device can adjust the bending amplitude of the steel bar. The locking ring 11 is twisted. The locking ring 11 displaces on the outer part of the locking shaft 10. The locking ring 11 contacts the outer wall of the slide rail 7, and can lock the slider 8.
