The curling groove 5 is opened in the middle position of the top surface of the detachable curling template 4. The detachable curling template 4 is installed in the groove in the middle position of the top surface of the machine platform 1 and is fixed by a locking bolt, which is convenient for replacing templates of different sizes and adapting to server chassis shells of various specifications. The curling groove 5 is opened in the middle position of the top surface of the detachable curling template 4 to guide the server chassis shell 6 into the curling area. The server chassis shell 6 is conveyed in the curling groove 5. The terminal of the moving component 3 is provided with a U-shaped clamping plate 10 for clamping on the top of the server chassis shell 6 so that the server chassis shell 6 is fed and transported in the curling groove 5.

[0040] Working principle:

[0041] The server chassis curling mechanism, the server chassis shell 6 is placed in the curling groove 5, which is a specific position preset at the top of the detachable curling template 4, for guiding and positioning the shell to be processed, the three-axis moving assembly 3, composed of an X-axis guide rail 12, a first Y-axis guide rail 13 and a Y-axis hydraulic lifting column 14, positions the U-shaped clamping plate 10 just above the server chassis shell 6, the U-shaped clamping plate 10 descends to the top of the server chassis shell 6, at this time the clamping cylinder 20 is started, and the clamping inner plate 21 is pushed by its piston rod to clamp the server chassis shell 6 centripetally from both sides to ensure its stability during subsequent processing, at this time the X-axis guide rail 12 drives the server chassis shell 6 to move in the curling groove 5 to a position facing the curling push plate 9 and then stops, the U-shaped clamping plate 10 rises under the control of the Y-axis hydraulic lifting column 14, the clamping cylinder 20 is retracted, and the server chassis shell 6 is released;

[0042] The hemming push cylinder 8 is opened, and its piston rod extends to push the hemming push plate 9 to move toward one end of the server chassis shell 6. When the hemming push plate 9 approaches, the hemming push plate 9 starts to apply pressure when it contacts the edge of the server chassis shell 6, forcing the edge material to deform and gradually roll into the hemming groove 5. In this process, the hemming positioning cross bar 11 plays a guiding and positioning role, ensuring the linear movement of the hemming push plate 9 and avoiding deviation during the hemming process.

[0043] When the edge of the server chassis shell 6 begins to curl, the curling pressing rod 18 moves downward together with the U-shaped clamping plate 10, applying additional pressure to the curling portion to ensure the integrity and stability of the curling shape. The rotating motor 19 can be activated at this stage, and the rotating motor 19 adjusts the direction and angle of the curling pressing rod 18 to apply force downward to the server chassis shell 6 to help the server chassis shell 6 curl;

[0044] After the curling process is completed, the electric telescopic rod 22 drives the unloading push rod 17 to move along the second Y-axis guide rail 15 to push the curled server chassis shell 6 out of the curling groove 5 to prepare for the next cycle.

[0045] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
