[0018] The lower die 12 is provided with a first cavity 17 into which the first tube 15 can be inserted and a second cavity 18 into which the first tube 15 can be inserted. The first cavity 17 and the second cavity 18 are parallel to each other and arranged side by side. The upper die 11 is provided with a notch punch 20 that can simultaneously notch cut the first tube 15 and the second tube 16. The lower die 12 is provided with a punch 19 into which the notch punch 20 can be inserted into the first cavity 17 and the second cavity 18.

[0019] The notched punch 20 includes a body fixedly connected to the upper die 11, a first punching part 21 fixedly disposed on the first side of the bottom of the body, and a second punching part 22 fixedly disposed on the second side of the bottom of the body.

[0020] When using the large-notch punching die for automotive seat tubing of this invention, the first tubing 15 can be inserted into the first cavity 17 of the lower die 12, while the second tubing 16 is simultaneously inserted into the second cavity 18 of the lower die 12. The upper die 11 moves downward, causing the notch punch 20 to extend into the first cavity 17 and the second cavity 18. The first punching part 21 and the second punching part 22 respectively perform notch punching on the first tubing 15 and the second tubing 16. The stamping die of this application only requires one die to realize the synchronous punching process of the first tubing 15 and the second tubing 16, reducing personnel and saving on punch presses, reducing the number of die changes and the number of scrapped products due to die change and debugging, saving processing costs, and greatly improving production efficiency.

[0021] Furthermore, in order to better position the first pipe 15 and the second pipe 16 and improve the processing accuracy, a positioning block 23 for blocking the first end of the first pipe 15 and the second pipe 16 is fixed inside the lower mold 12.
