[0014] like Figure 1-4 As shown, this embodiment is a bending fixture for manufacturing U-shaped screws, including a pressure roller 5 and a forming fixture. The forming fixture includes a base 4, on which two sets of support roller 3 mechanisms are symmetrically mounted on both sides. Each set of support roller 3 mechanisms includes a support seat 2, which is slidably connected to the base 4. The support seat 2 is mounted on the upper end of the support seat 2, and the support roller 3 is rotatably connected to the support seat 2. A groove is provided in the middle of the outer surface of the support roller 3, and the width of the groove is greater than the diameter of the screw. A support plate 1 is provided on each side of the base 4. The support plate 1 is provided with a threaded hole, and an adjusting screw 7 is installed in the threaded hole. A locking nut 8 is installed on each side of the adjusting screw 7 located on the support plate 1. One end of the adjusting screw 7 is rotatably connected to the support seat 2 of the corresponding support roller 3 mechanism.

[0015] Furthermore, the base 4 is equipped with an arc-shaped limiting block 6 in the middle, and the upper surface of the arc-shaped limiting block 6 is provided with an arc-shaped groove.

[0016] Furthermore, the arcuate limiting block 6 is connected to the base 4 by bolts.

[0017] Furthermore, a groove is provided in the middle of the outer surface of the pressure roller 5, and the width of the groove is greater than the diameter of the screw. The working principle of this utility model is as follows: According to the curvature of the U-shaped screw to be bent, adjust the distance between the two support rollers 3 and select a suitable arc limit block 6; the distance between the two support rollers 3 is adjusted by turning the adjusting screw 7 to push or pull the support seat 2, so that the support seat 2 slides on the base 4, thereby adjusting the distance between the two support rollers 3. After adjustment, tighten the locking nuts 8 on both sides; then install the pressure roller 5 on the press, the diameter of the pressure roller 5 is adapted to the curvature of the bending, the base 4 is placed on the worktable of the press and positioned so that the groove of the pressure roller 5 is aligned with the groove of the support roller 3 in a vertical plane. After installation and fixation, the U-shaped screw can be pressed. Place the straight screw flat in the groove of the two support rollers 3, and then start the press to press the pressure roller 5 to the bottom, so that the screw can be bent into shape.
