[0034] The implementation principle of a furniture metal pipe punching device in an embodiment of this application is as follows: First, pull out the placement box 8 by pulling the fixing box 19, then place the furniture metal pipe in the placement box 8, and finally push the fixing box 19 to the leftmost side to start the punching operation. During the process of the placement box 8 moving to the left, under the action of the toothed plate 18, the gear 17 rotates, causing the threaded rod 16 to rotate, so that the two threaded barrels 15 respectively drive the two adjusting plates 9 to move away from each other. After pulling out the placement box 8, place the furniture metal pipe in the middle of the placement box 8. After placement is completed, push the placement box 8 to the leftmost side. During this process, the gear 17 is affected by the toothed plate 18, causing the threaded rod 16 to rotate in the reverse direction, so that the two threaded barrels 15 respectively drive the two adjusting plates 9 to move relatively, causing the two abutting plates 10 to gradually abut against the surface of the furniture metal pipe, thereby fixing and clamping the furniture metal pipe. It realizes the automatic fixation of the furniture metal pipe during the process of pushing and pulling out the placement box 8. At the same time, the furniture metal pipe will be automatically fixed to the middle position of the placement box 8, improving the working efficiency of the device and reducing the situation of dislocation of the furniture metal pipe.

[0035] When the diameter size of the furniture metal pipe changes, rotate the second bevel gear 14, causing the second bevel gear 14 to drive the first bevel gear 13 to rotate, so that the adjusting screw rod 12 rotates, so that the adjusting cylinder 11 drives the abutting plate 10 to move horizontally, enabling the furniture metal pipe to be clamped and fixed when the placement box 8 moves to the leftmost side, enabling the device to adapt to the clamping and fixing of furniture metal pipes with different diameter sizes and improving the applicable range of the device.

[0036] When the placement box 8 moves to the leftmost side, rotate the threaded pressure rod 23 so that the threaded pressure rod 23 moves downward along the piston cylinder 22, and the air in the piston cylinder 22 pushes the abutting rod 21 downward, so that the pressing plate 20 drives the two insertion rods 24 to insert into the socket on the workbench 1, forming a fixation for the placement box 8. Then start the hydraulic telescopic rod, so that the punching die punches the furniture metal pipe, enabling the placement box 8 to be fixed when the device is performing the punching operation, improving the stability of the device.
