[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example: A sheet metal bending angle repair tool, such as Figures 1-4 As shown, it includes a base frame 1, a worktable 2, a first screw 3, a fixing plate 4, a rotating plate 5, a handle 6, a calibration component, and a straightening component. The worktable 2 is connected to the top of the base frame 1. The first screw 3 is symmetrically and rotatably connected to the middle of the top of the worktable 2. The fixing plate 4 for pressing the sheet metal parts is threaded between the first screws 3. The bottom of the fixing plate 4 is connected to a soft pad to increase the tightness with the sheet metal parts and to avoid wear on the sheet metal parts. The rotating plate 5 for adjusting sheet metal parts with a bending degree greater than 90 degrees is rotatably connected to the left side of the worktable 2. The handle 6 is symmetrically welded to the bottom of the rotating plate 5. The calibration component and the straightening component are provided on the top of the worktable 2.

[0021] like Figure 1 and Figure 3 As shown, the calibration assembly includes a limiting plate 7, a guide frame 8, a support block 9, a second screw 10, a push rod 11, and an angle ruler 12. The limiting plate 7 is symmetrically connected to the left side of the worktable 2 in a rotating manner. Angle rulers 12 are symmetrically connected to the left side of the worktable 2 in a rotating manner. The rotation points of the limiting plate 7 and the rotating plate 5 are both on the same straight line as the angle ruler 12. The limiting plate 7 is in a vertical state, and the rotating plate 5 is in a horizontal state. The rotation angle of the limiting plate 7 can be referenced from the data on the angle ruler 12. Two guide frames 8 are connected to the right side of the limiting plate 7. Support blocks 9 are welded to the top of the worktable 2 at the position to the right of the limiting plate 7. The second screw 10 is threadedly connected to the support block 9. The push rod 11 is rotatably connected to the left end of the second screw 10. The push rod 11 is slidably connected to the two adjacent guide frames 8.

[0022] like Figure 1 and Figure 4 As shown, the correction assembly includes a fixed block 13, a movable plate 14, and a pull handle 15. Fixed blocks 13 are welded to the inner side of the limiting plate 7 on the workbench 2. A movable plate 14 for adjusting sheet metal parts with a bending degree of less than 90 degrees is rotatably connected between the two fixed blocks 13. Pull handles 15 are symmetrically welded to the top of the movable plate 14.

[0023] When the normal shape of the sheet metal part is L-shaped and the bent part is in a vertical state, the device can be used for repair work. When placing the sheet metal part, the flat part of the sheet metal part is inserted from below the movable plate 14 and placed on the workbench 2, so that it is located directly below the fixed plate 4, and the vertical or bent part is kept in an upward state. By rotating the first screw 3, the fixed plate 4 is driven to move downward, effectively compressing the sheet metal part and ensuring its stability during the repair process. For the case where the bending degree is greater than 90 degrees, the repair process is completed by rotating the plate 5. First, adjust the angle of the limiting plate 7 according to the angle to be repaired, so that it matches the correct angle of the sheet metal part. During adjustment, rotate the second screw 10 forward or backward to drive the push rod 11 to rotate the guide frame 8 and the limiting plate 7 forward or backward accordingly. The operator can monitor the rotation angle of the limiting plate 7 in real time through the angle ruler 12 to ensure its accuracy.

[0024] After adjustment, the operator holds the handle 6 and rotates the rotating plate 5 upward, so that it tightly fits the bent part of the sheet metal part, applies pressure from the outside to the inside, gradually reduces the included angle until the rotating plate 5 is completely fitted with the limiting plate 7, thereby achieving the required repair angle. After repair is completed, reverse the rotating plate 5 to reset, then reverse the first screw 3 to move the fixed plate 4 upward, release the fixation of the sheet metal part, and finally take out the repaired sheet metal part.

[0025] For sheet metal parts with a bending degree less than 90 degrees, the movable plate 14 can be used for repair. Similarly, first adjust the position of the limiting plate 7 according to the angle to be repaired to ensure that it meets the correct angle requirement, then the operator holds the pull handle 15 and pulls the movable plate 14 upward, so that it tightly fits the bent part of the sheet metal part, pushes the bent part from the inside to the outside, gradually expands the included angle, until the movable plate 14 is aligned with the limiting plate 7, and the repair work is completed. Throughout the process, the operator should always maintain precise control of the force and angle to ensure repair quality and safety of the workpiece.

[0026] The above embodiments are provided to those skilled in the art to implement or use the present application, and those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present application, therefore the protection scope of the present application is not limited by the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
