[0027] Further, such as Figure 1As shown, a steel bar seat 5 is rotatably connected to the fixed shaft 12; the side of the steel bar seat 5 is designed in a C-shaped structure; before use, the steel bar is placed inside the steel bar seat 5, and the steel bar seat 5 is used to improve its contact with the fixed shaft 12, so as to increase the contact area with the surface of the steel bar, thereby reducing the movement of the steel bar when bending at the beginning.

[0030] Working principle: before bending the steel bar, the staff can rotate the first screw 13 according to the thickness of the steel bar and the bending arc diameter. The rotation of the first screw 13 will drive the screw sleeve to move up and down, so as to adjust the position of the slide 14 through the connecting rod 17. The bottom of the slide 14 slides in the slide groove 16, and the positions of the multiple first pillars 15 are synchronously adjusted by the above.

The servo motor 21 is used to control the angle of the steel bar bending. When the first pillar 15 is adjusted, the staff The staff can rotate the second screw rod 33, and then under the action of the thread, drive the bending seat 32 to move, so that it slides on the adjustment seat 31, so as to adjust the position of the second support 25, so that it contacts the steel bar, so that after the first support 15 adjusts its position, the second support 25 bends the steel bar. When the slide 14 moves, the slide 14 slides on the guide rod 41, and the guide rod 41 can support the slide 14 to improve its stability. When the driven gear 23 rotates, it will drive the connecting ring 42 to move on the support The support ring 43 rotates to support the rotation of the driven gear 23, and then supports the rotation of the slider 24, thereby improving the stability during the bending process. Before use, the steel bar is placed inside the steel bar seat 5, and the steel bar seat 5 is used to increase its contact with the fixed shaft 12, so as to increase the contact area with the surface of the steel bar, thereby reducing the movement of the steel bar at the beginning of bending, and relying on the rotation connection of the first support 15 and the second support 25, the friction on the first support 15 and the second support 25 can be reduced, thereby reducing the wear on the same part.
