[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model comprises a frame and a supporting mechanism and a calibrating mechanism arranged inside the frame.

[0026] The frame includes a bottom plate 1 , a top plate 2 , and a plurality of columns 3 disposed between the bottom plate 1 and the top plate 2 .

[0027] The support mechanism includes two side panels 5 and a roller 6 disposed between the two side panels 5 . The lower parts of the two side panels 5 are connected via a base 4 . The base 4 and the side panels 5 are both placed on the bottom plate 1 .

[0028] The calibration mechanism includes a transmission shaft 8 and a calibration pressure wheel 10 fixedly mounted on the transmission shaft 8, one end of the transmission shaft 8 is connected to the output shaft of the motor 7, two mounting plates 9 are provided at the lower part of the top plate 2, the two mounting plates 9 are respectively located on both sides of the calibration pressure wheel 10, a bearing 12 for the transmission shaft 8 to pass through is provided in the mounting plate 9, a U-profile 11 is located at the lower part of the calibration pressure wheel 10, and the thickness of the calibration pressure wheel 10 is adapted to the inner notch of the U-profile 11 after calibration.

[0029] In actual use, by setting up the aligning mechanism, it is convenient to use the transmission shaft 8 to drive the aligning pressure wheel 10 to rotate, so that the aligning pressure wheel 10 rolls in the U-profile 11, and corrects the narrowed mouth of the U-profile 11, thereby solving the unevenness such as twisting or warping of the mouth of the U-profile 11, improving the forming qualification rate of the U-profile 11, and having high straightening accuracy, meeting the market needs for the forming and straightening of special materials and U-profiles with complex cross-sections, and having good use effect.

[0030] In actual use, by providing the mounting plate 9 , the transmission shaft 8 can be conveniently installed in the frame, and by providing the bearing 12 , when the motor 7 drives the transmission shaft 8 to rotate, the transmission shaft 8 can realize self-rotation in the bearing 12 .

[0031] It should be noted that the thickness of the calibrating wheel 10 is the standard inner diameter of the U-profile 11. By setting the thickness of the calibrating wheel 10 to be compatible with the inner notch of the calibrated U-profile 11, it is convenient to calibrate the U-profile 11 with a twisted or warped mouth into a U-profile 11 with a straight mouth, and the inner notch width of the calibrated U-profile 11 is the same as the thickness of the calibrating wheel 10.

[0032] like Figure 2 As shown, in this embodiment, there are multiple rollers 6 , and the multiple rollers 6 are arranged side by side along the moving direction of the U-profile 11 .

[0033] In actual use, by providing the roller 6, when the calibrating pressure wheel 10 drives the U-profile 11 to move forward and backward, the resistance on the bottom of the U-profile 11 is reduced, and the loss of the U-profile 11 is avoided, which is highly practical.

[0034] In this embodiment, the distance between the mounting plate 9 and the calibrating pressure wheel 10 is greater than the side wall thickness of the U-profile 11 .

[0035] In actual use, by setting the distance between the mounting plate 9 and the calibrating pressure wheel 10 to be greater than the side wall thickness of the U-profile 11 , it is convenient to avoid the mounting plate 9 from affecting the U-profile 11 when calibrating the U-profile 11 .

[0036] In this embodiment, the distance between the calibrating pressure wheel 10 and the roller 6 is adapted to the bottom wall thickness of the U-profile 11 .

[0037] In actual use, by setting the distance between the calibrating pressure wheel 10 and the roller 6 to be equal to the bottom wall thickness of the U-profile 11, the calibrating pressure wheel 10 and the roller 6 can clamp the bottom of the U-profile 11, thereby facilitating the calibrating pressure wheel 10 to drive the U-profile 11 to move forward and backward.

[0038] When the utility model is used, the U-profile 11 is inserted between the calibrating pressure wheel 10 and the roller 6, and then the motor 7 is started to make the transmission shaft 8 drive the calibrating pressure wheel 10 to rotate, thereby correcting the mouth of the U-profile 11. When the deformation of the U-profile 11 is too large to move, the technician can manually push the U-profile 11 back and forth, so that the calibrating pressure wheel 10 can correct the mouth of the U-profile 11.
