[0002] A U-shaped bolt refers to a bolt whose two ends are respectively composed of hanging rings and threaded rods. The two ends of the threaded rod can be tightened by nuts to realize the fastening of connecting parts. Due to reasons such as quenching, the U-shaped bolt is prone to deformation. Therefore, it is necessary to correct the U-shaped bolt to make it meet the production standards. At present, the correction of the U-shaped bolt is carried out on a punching machine. After heat treatment such as heating the deformed part, a special tool is used for correction.

In the utility model, for the flattening processing of the screw rod of the U-shaped bolt at a certain angle, first, the hanging ring of the U-shaped bolt is placed on the positioning groove on the sliding seat, and the U-shaped bolt is preliminarily positioned through the positioning groove. By pushing the push rod, the U-shaped bolt gradually moves towards the positioning block through the sliding seat, and the opened screw rod contacts the bottom wall of the first arc groove. The staff can manually assist, and then start the hydraulic cylinder to carry out flattening processing on the U-shaped bolt. However, the number of U-shaped bolts corrected at one time in this prior art is limited, which is not conducive to improving the overall processing efficiency. Content of the Utility Model

[0025] The following further describes the present utility model in detail with reference to the embodiments:

[0026] Embodiment 1

[0027] As Figures 1-5As shown in the figure, the utility model provides a flattening device for U-bolt processing, which includes a base 1 and a support plate 2. A partition plate 3 is fixedly connected to the upper surface of the base 1. A positioning seat 8 and a calibration pushing block 6 are respectively arranged on the left and right sides of the partition plate 3. An adaptation chute 13 is opened on the side of the calibration pushing block 6 away from the partition plate 3. A calibration slider 12 is slidably connected to the inner wall of the adaptation chute 13. A calibration cross bar 5 is fixedly connected to the side of the calibration slider 12 away from the calibration pushing block 6.

[0028] The bottom surface of the positioning seat 8 is fixedly connected with an auxiliary slider 15. An adjustment chute 9 for adapting the auxiliary slider 15 is opened on the upper surface of the base 1.

[0029] The side of the calibration cross bar 5 away from the calibration pushing block 6 is rotatably connected with a calibration hydraulic push rod 4 through a shaft seat. The side of the positioning seat 8 away from the partition plate 3 is fixedly connected with a positioning hydraulic rod 10.

[0030] The outer wall of the calibration slider 12 is slidably connected with the inner wall of the adaptation chute 13. The outer wall of the auxiliary slider 15 is slidably connected with the inner wall of the adjustment chute 9.

[0031] An inner arc groove is opened on the side of the calibration pushing block 6 away from the calibration cross bar 5. A rubber sticker layer 14 is fixedly connected to the inner wall of the inner arc groove. When the left and right ends of the U-bolt are gradually fitted during calibration, the calibration cross bar 5 slides downward on one side of the calibration pushing block 6 under the push of the calibration hydraulic push rod 4. At this time, the calibration slider 12 slides on the inner wall of the adaptation chute 13, while the calibration pushing block 6 and the U-bolt maintain the initial contact area without change, thereby avoiding the influence on the U-bolt thread and being able to maintain continuous pressure on the U-bolt to improve the calibration efficiency.

[0032] Embodiment 2

[0033] As Figures 1-5 shown, on the basis of Embodiment 1, the utility model provides a technical solution: Preferably, a collar 11 is fixedly connected to the top of the partition plate 3, and a mounting post 7 is fixedly connected to the inner wall of the collar 11.

[0034] The number of the partition plates 3 is at least two groups, and the two groups of partition plates 3 are equidistantly distributed on the upper surface of the base 1.

[0035] The positioning seat 8 includes positioning columns. A docking hole is provided at the top of the positioning columns. The positioning columns in the positioning seat 8 are composed of positioning columns with increasing heights, and the positioning columns are combined side by side. When calibrating U-bolts of different lengths, the positioning hydraulic rod 10 can be activated, so that the positioning hydraulic rod 10 pushes the positioning seat 8 close to the partition plate 3 to a suitable position. Then, one end of the U-bolt is inserted into the adapted positioning column, and then the calibration hydraulic push rod 4 can be activated to perform the calibration work. One side of the calibration push block 6 is movably connected to one side of the partition plate 3, and the end of the calibration hydraulic push rod 4 away from the calibration push block 6 is rotatably connected to one side of the support plate 2.

[0036] Next, the working principle of the flattening device for U-bolt processing will be specifically described.

[0037] As Figures 1-5 shown, the U-bolt is hung on the mounting column 7, and one end of it is inserted into the docking hole on the positioning seat 8. Then, the calibration hydraulic push rod 4 is activated. When the calibration hydraulic push rod 4 pushes the calibration cross bar 5 close to the other end of the U-bolt, the calibration cross bar 5 pushes the calibration push block 6 to gradually fit with the U-bolt. As the output end of the calibration hydraulic push rod 4 continuously moves forward, the angle between the calibration push block 6 and the base 1 also gradually increases at this time, and the U-bolt is continuously calibrated.

[0038] When the left and right ends of the U-bolt are gradually fitted during calibration, the calibration cross bar 5 slides downward on one side of the calibration push block 6 under the push of the calibration hydraulic push rod 4. At this time, the calibration slider 12 slides on the inner wall of the adapted chute 13, and the calibration push block 6 and the U-bolt maintain the initial contact area without change, thus avoiding affecting the threads of the U-bolt and being able to continuously apply pressure to the U-bolt to improve the calibration efficiency.

[0039] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
