[0002] The promotion and application of LED light sources is a new revolution in the field of lighting. Its luminous efficiency has exceeded 1001m / W, and it is expected to occupy a dominant position in the field of lighting. Compared with traditional lighting sources, it has many advantages such as long life, low energy consumption, and high controllability. Thousands of holes are generally processed on LED lamp tubes for the installation and fixation of accessories on the lamp tubes. At present, when processing multiple holes around some cylindrical or square hollow metal lamp tubes, punching machines are generally used for processing, and corresponding types of punching molds are installed on the punching machines.

In the initial state, the punch 18 and the bottommost positioning hole 9 on the positioning column 8 are in corresponding positions to facilitate punching of the lamp tube body 10. An anti-slip sleeve is provided on the outside of the positioning column 8. When the lamp tube body 10 is sleeved on its outside, the anti-slip sleeve contacts the inner wall of the lamp tube body 10, thereby ensuring the stability of the position of the lamp tube body 10 relative to the positioning column 8.

[0024] A stamping assembly 25 is arranged on the top of the base plate 1 outside the support plate 4, an electric push rod 11 is fixedly connected to the top center of the top plate 3, and the piston rod end of the electric push rod 11 passes through the top plate 3 and is connected to a pressure plate 12, which contacts the top of the positioning column 8.

[0025] It should be noted that when the utility model is used, the lamp tube body 10 to be punched is sleeved on the outer side of the positioning column 8. A positioning hole 9 for corresponding to the punch is opened on the outer side of the positioning column 8. In the initial state, the end of the punch 18 corresponds to the position of the positioning hole 9 at the bottom of the positioning column 8. When punching, the control system set by the device controls the electric push rod 11 to work, so that the pressure plate 12 is pressed down on the top of the positioning column 8, and the cylinder 16 is controlled to work, so that the punch 18 punches the outer side of the lamp tube body 10. After the first punching is completed, the control system controls the rotating motor 7 to work, so that the gear 6 rotates, and the support plate 4 is rotated a certain angle through the meshing connection between the gear 6 and the outer gear ring 5, and then the cylinder 16 works again to punch. After the punching of the bottom end of the lamp tube body 10 is completed, the control system controls the servo motor 23 to work so that the stamping assembly 25 moves up a certain height, and then the stamping plate 17 works to punch, and then the rotating motor 7 continues to control the rotation of the positioning column 8 to achieve sequential punching of the lamp tube body 10.

The stamping plate 17 is fixedly connected to the punch 18 in the middle of the side away from the lifting plate 15.

[0029] It should be noted that after the position of the lamp tube body 10 is fixed, the stamping plate 17 can be pushed to move by controlling the cylinder 16, and the punch 18 on the stamping plate 17 rushes toward the lamp tube body 10. The end of the punch 18 passes through the lamp tube body 10 and is placed in the positioning hole 9 to punch the lamp tube body 10.
