By placing the steel pipe to be punched between the first U-shaped plate 4 and the second U-shaped plate 7, so that one end of the steel pipe abuts against the first U-shaped plate 4, and then extending the output end of the cylinder 5 to move the mounting plate 6, the mounting plate 6 moves the second U-shaped plate 7 closer to the first U-shaped plate 4, thereby clamping and positioning the steel pipe through the first U-shaped plate 4 and the second U-shaped plate 7. Clamping mechanisms 8 are provided on opposite sides of the U-shaped plate 4 and the second U-shaped plate 7. Both clamping mechanisms 8 include a first clamping plate 81 and a second clamping plate 82. The two first clamping plates 81 are fixedly connected to the second U-shaped plate 7 and the first U-shaped plate 4, respectively. A screw 83 is threaded onto one side of both the first U-shaped plate 4 and the second U-shaped plate 7. The end of the screw 83 near the first clamping plate 81 is rotatably connected to the second clamping plate 82, and a knob 84 is provided at the end of the screw 83 away from the second clamping plate 82. By placing the steel pipe... On the first clamping plate 81, the knob 84 is rotated to drive the screw 83 to rotate, which in turn drives the second clamping plate 82 to move closer to the first clamping plate 81. The steel pipe is then clamped and fixed by the second clamping plate 82 and the first clamping plate 81. A first limiting rod 85 is fixedly provided on the surface of the second clamping plate 82. A first through hole is opened on one side of the second U-shaped plate 7 for the first limiting rod 85 to slide through.

The debris in the collection box 12 is discharged through the hole at the bottom.
[0024] The specific working principle of this utility model is as follows: The steel pipe to be punched is placed between the first U-shaped plate 4 and the second U-shaped plate 7, with one end of the steel pipe abutting against the first U-shaped plate 4. The steel pipe is then placed on the first clamping plate 81. The output end of the cylinder 5 extends, causing the mounting plate 6 to move. The mounting plate 6 moves the second U-shaped plate 7 closer to the first U-shaped plate 4, thereby clamping and positioning the steel pipe using the first U-shaped plate 4 and the second U-shaped plate 7. Then, the knob 84 is rotated, causing the screw 83 to rotate, which in turn moves the second clamping plate 82 closer to the first clamping plate 81. Finally, the second clamping plate 82 and the first U-shaped plate 81... A clamping plate 81 holds and fixes the steel pipe. The output end of the hydraulic rod 94 drives the drilling machine 95 to move downward, punching holes in the steel pipe. The second motor 92 drives the lead screw 91 to rotate, which in turn drives the moving block 93 to move along the lead screw 91. The moving block 93 drives the punching assembly to move, which facilitates positioning and punching at different positions of the steel pipe. The first motor 3 drives the first U-shaped plate 4 to rotate, which in turn drives the first U-shaped plate 4 and the second U-shaped plate 7 to clamp and rotate the steel pipe, adjusting the orientation angle of the steel pipe, which facilitates all-round punching of the steel pipe.
