[0017] Preferably, a rubber pad is fixedly connected to the inner wall of the arc-shaped block, and the arc surface of the rubber pad is provided with a plurality of evenly distributed protrusions.

[0018] The effect achieved by the above components is to increase the friction between the circular tubular plastic parts and the arc-shaped blocks by setting rubber pads.

[0019] Preferably, an airbag is fixedly connected to one side of the limiting block, and the arc surface of the airbag is fixed to each of the stamped cylinders.

[0020] The effect achieved by the above components is: to activate the airbag, causing the airbag to inflate, thereby squeezing the arc-shaped block, and thus assisting in the clamping of the circular tubular plastic part by the arc-shaped block.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a punching assembly, when punching square holes in round tubular plastic parts, the square punch is rotated to connect with the threaded groove, and then the punching cylinder is rotated so that the square punch is below the square punch, thereby activating the cylinder and causing the square punch to punch square holes in the round tubular plastic parts. This solves the problem that when punching square holes in the surface of round tubular plastic parts, it is necessary to replace the square punch and the punching cylinder, which in turn requires replacing the square punch and the square punch, thus affecting the punching efficiency of round tubular plastic parts.

[0029] The specific settings and functions of the punching component 2 and the clamping component 3 will be explained below.

[0030] Reference Figure 2 and Figure 3 As shown, in this embodiment: the punching assembly 2 includes a square punch 21 slidably connected to the arc surface of the circular punch 8. The arc surface of the circular punch 8 is provided with a threaded groove 22, which is threadedly connected to the square punch 21. The arc surface of the stamping cylinder 10 is provided with a square punch 23. By setting the punching assembly 2, when punching a square hole in a circular tube plastic part, the square punch 21 is rotated so that it is threadedly connected to the threaded groove 22. Then the stamping cylinder 10 is rotated so that the square punch 23 is below the square punch 21, thereby activating the cylinder 5, which in turn causes the square punch 21 to punch a square hole in the circular tube plastic part. The right end of the fixing block 9 is fixedly connected to a limiting block 24. The arc surface of the limiting block 24 is rotatably connected to a rotating ring 25. Each stamping cylinder 10 is slidably connected to the rotating ring 25. The arc surface of the limiting block 24 is provided with multiple evenly distributed circular grooves 26. The inner wall of the circular grooves 26 is slidably connected to a pin 28, which is inserted into the groove. The upper end of the rotating ring 25 is fixedly connected to a spring 27 and a pull rope 29. Pulling the pull rope 29 and the spring 27 causes the pin 28 to fully retract into the circular groove 26. Rotating the stamping cylinder 10 causes the square punch 23 to be positioned below the square punch 21. Loosening the pull rope 29 causes the pin 28 to engage with the rotating ring 25, thereby fixing the stamping cylinder 10. The other end of the spring 27 is fixed to the limiting block 24, and the pull rope 29 passes through the limiting block 24 and... The fixing block 9, by setting the spring 27, resets the pin 28. The upper end of the square punch 21 is fixedly connected to the magnetic sheet 211, and the lower end of the mounting cover 7 is fixedly connected to the magnetic sheet 210. By setting the magnetic sheet 211 and the magnetic sheet 210, the square punch 21 is limited. When the magnetic sheet 211 and the magnetic sheet 210 are close, they attract each other. The surface of the pull rope 29 is fixedly connected to the rubber sleeve. By setting the rubber sleeve, the friction on the pull rope 29 is reduced.

[0031] Reference Figure 3As shown in this embodiment: the clamping assembly 3 includes an electric telescopic rod 31 installed at one end of the support frame 4. An arc-shaped block 32 is fixedly connected to the output end of the electric telescopic rod 31. When the electric telescopic rod 31 is activated, the arc-shaped block 32 is pressed against the circular tube plastic part, thus fixing the circular tube plastic part to the stamped cylinder 10. A rubber pad 33 is fixedly connected to the inner wall of the arc-shaped block 32. The arc surface of the rubber pad 33 is provided with multiple evenly distributed protrusions. By setting the rubber pad 33, the friction between the circular tube plastic part and the arc-shaped block 32 is increased. An airbag 34 is fixedly connected to one side of the limiting block 24. The arc surface of the airbag 34 is fixed to each stamped cylinder 10. When the airbag 34 is activated, the airbag 34 inflates, thereby pressing the arc-shaped block 32, thus assisting the arc-shaped block 32 in clamping the circular tube plastic part.

[0032] Working principle:

[0033] When punching holes in the surface of a circular plastic tube, the circular plastic tube is placed on the punching cylinder 10 on the fixing block 9 of the fixing frame 6. The cylinder 5 on the support frame 4 of the base 1 is activated, causing the circular punch 8 to move down and punch holes in the surface of the circular plastic tube. Then, the circular punch 8 moves down into the circular punch hole 11, completing the punching of the circular plastic tube. When punching square holes in the circular plastic tube, the square punch 21 is rotated to connect with the threaded groove 22. Then, the punching cylinder 10 is rotated so that the square punch hole 23 is below the square punch 21, thereby activating the cylinder 5. This causes the square punch 21 to punch square holes in the circular plastic tube. Pulling the pull rope 29 and the spring 27 causes the pin 28 to fully retract into the circular groove 26. The punching cylinder 10 is then rotated. The square punch 23 is positioned below the square punch 21. The pull rope 29 is loosened, causing the pin 28 to engage with the rotating ring 25, thereby fixing the stamping cylinder 10. The pin 28 is reset by the spring 27. The square punch 21 is limited by the magnetic sheet 211 and the magnetic sheet 210. The friction of the pull rope 29 is reduced by the rubber sleeve. The electric telescopic rod 31 is activated, causing the arc block 32 to press against the circular tube plastic part. The circular tube plastic part is fixed to the stamping cylinder 10. The friction between the circular tube plastic part and the arc block 32 is increased by the rubber pad 33. The airbag 34 is activated, causing the airbag 34 to inflate, thereby pressing the arc block 32 and assisting the arc block 32 in clamping the circular tube plastic part.
