[0024] The present application is composed of a fixed end 1 and a movable end 3 with adjustable spacing. According to the different size specifications of the steel bar, the center of gravity position is different. The fixed end 1 and the movable end 3 with adjustable spacing can make corresponding changes according to the change of the center of gravity of the steel bar, thereby ensuring that the center of gravity of the steel bar will not shift and cause the steel bar to deflect. Figure 1 As shown, both the fixed end 1 and the movable end 3 are provided with a clamping assembly for clamping the steel bar for fixing, wherein the fixed end 1 is provided with a rotating assembly for driving the clamping assembly to rotate in a radial direction, as shown in FIG. Figure 2 The clamping assembly shown on the fixed end 1 is installed on the rotating assembly, and the rotating assembly includes a steering part 11 arranged at the top of the fixed end 1. The steering part 11 is a hollow ring, and the outer walls at both ends are installed with gear rings. The fixed end 1 is rotatably connected with a gear 15 that is kneaded with the gear ring. The gear 15 is provided with two gear rings that are respectively meshed with the gear rings provided on both ends of the steering part 11. The two gears 15 are connected through an optical axis. A self-locking motor 14 is installed on the fixed end 1, and the output shaft of the self-locking motor 14 is connected to the optical axis. The two gears 15 are driven to rotate by the self-locking motor 14, thereby driving the steering part 11 connected thereto to rotate in the opposite direction, and controlling the clamping assembly installed on the steering part 11 to rotate in the same direction. Further, as Figure 3 and Figure 4 As shown, in order to ensure that the steering part 11 can rotate on the end face of the fixed end 1 close to the steel bar with its own axis as the reference line, sliding grooves 12 are symmetrically arranged at both ends of the steering part 11. The sliding grooves 12 are arc-shaped and have the same center as the steering part 11. The fixed end 1 is provided with support rods 13 with the same number as the sliding grooves 12. The support rods 13 abut against the corresponding sliding grooves 12. The sliding grooves 12 cooperate with the support rods 13 to enable the steering part 11 to stably rotate on the fixed end 1 and ensure that the axis line of the steering part 11 remains unchanged.

[0025] like Figure 2 As shown, the clamping assembly includes a hydraulic rod 2 and a clamping portion 21. The clamping portion 21 is arc-shaped to increase its contact area with the steel bar so as to improve the stability of the clamping portion 21 clamping the steel bar. Two clamping portions 21 are provided, and the two clamping portions 21 are arranged opposite to each other to form a cavity for clamping the steel bar. The cavity can fix the steel bar so that the steel bar will not move along its axial direction during the process of the device processing the steel bar, thereby ensuring the accuracy of the device processing. A hydraulic rod 2 is connected to the end of the clamping portion 21 away from the steel bar. The hydraulic rod 2 is used to change its own length to push the clamping portion 21 to move along the axial direction of the hydraulic rod 2. The axial center lines of the two hydraulic rods 2 are arranged collinearly to change the distance between the two clamping portions 21. As shown Figure 1 As shown, the clamping assembly arranged on the fixed end 1 is arranged on both ends of the steering part 11, the two hydraulic rods 2 are respectively arranged on both ends of the outer wall of the steering part 11 and penetrate the steering part 11, and the two clamping parts 21 are arranged inside the steering part 11, and it is ensured that the axis of the cavity formed by the two clamping parts 21 is arranged in a collinear manner with the axis of the steering part 11, so that when the cavity clamps the steel bar, the axis of the steel bar is arranged in a collinear manner with the axis of the steering part 11. Figure 6 As shown, the clamping assembly arranged on the mobile end 3 is fixed on the mobile end 3, wherein the two hydraulic rods 2 are respectively fixed on the two ends of the mobile end 3 and are symmetrically arranged, and the axis line of the cavity formed by the two clamping parts 21 is colinearly arranged with the axis line of the cavity formed by the two clamping parts 21 arranged on the fixed end 1, ensuring that the axis line of the steel bar remains stationary when the steel bar moves axially on the device.

[0026] In order to further ensure the stability of the rotation of the steering portion 11 on the fixed end 1, the end surface of the fixed end 1 in contact with the steering portion 11 is provided with a Figure 4 The groove shown has a width greater than the sum of the diameter of the steering portion 11 and the length of the hydraulic rod 2 installed on the steering portion 11, so that the hydraulic rod 2 will not be blocked by the fixed end 1 when rotating with the steering portion 11.

[0027] The device clamps and fixes the steel bar and then bends the steel bar, wherein the moving end 3 is provided with a Figure 6The bending portion 32 shown is fixedly connected to the moving end 3. The top of the bending portion 32 is a raised arc and a cylinder 31 is installed at the bottom. The axis of the cylinder 31 is perpendicular to the axis of the steel bar. The cylinder 31 is fixedly connected to the moving end 3. The cylinder 31 is used to push the bending portion 32 to move along its axial direction, and the bending portion 32 fits the adjacent end of the clamping portion 21. During the movement of the bending portion 32 and the bending of the steel bar, the bending end is fixed by the two clamping portions 21 to ensure the accuracy of the bending of the steel bar. When the bending direction of the steel bar needs to be changed, the rotation of the steering portion 11 is used to drive the steel bar to rotate radially in the same direction, thereby changing the bending direction of the steel bar and making its bending direction the same as the axial direction of the cylinder 31, so as to achieve bending of the steel bar in any radial direction.

[0028] Furthermore, in order to ensure the stability of the support of the fixed end 1 and the mobile end 3 while changing the distance between the fixed end 1 and the mobile end 3, a support structure such as Figure 1 The sleeve 4 shown is provided with two sleeves 4, which are symmetrically arranged at the two ends of the fixed end 1, respectively. A slide bar 42 is sleeved on the sleeve 4, and a positioning hole 41 is arranged on the sleeve 4. A plurality of fixing holes 43 are arranged on the slide bar 42 at equal intervals along the length direction, wherein any fixing hole 43 that coincides with the positioning hole 41 is locked by inserting a locking part, so that the slide bar 42 cannot slide in the sleeve 4. The locking part is usually a screw, an optical axis, etc. according to the locking requirements. In order to facilitate the staff to push the mobile end 3, a roller to reduce friction is arranged at the bottom end of the mobile end 3.
