[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 3 A novel automatic wheel spoke punching die is provided, comprising an upper die assembly, a wheel spoke workpiece 1, and a lower die assembly. The upper die assembly includes an upper template 2, with a mounting plate 3 fixed below the upper template 2. Multiple hollow punches 4 are arranged around the mounting plate 3, and vertical guide rods 5 are fixed around the upper template 2.

[0018] The lower mold assembly includes a lower mold plate 6, on which a cylinder 7 corresponding to the guide rod 5 is fixed. The lower mold plate 6 is provided with a first frame 8 and a second frame 9. The first frame 8 is fixedly connected to the lower mold plate 6. The first frame 8 is fixed with a first inclined baffle 10 at the front and rear. The two first inclined baffles 10 are symmetrical about the middle position of the first frame 8. The second frame 9 is slidably connected to the lower mold plate 6. The second frame 9 is fixed with a second inclined baffle 11 at the front and rear. The two second inclined baffles 11 are symmetrical about the middle position of the second frame 9. The spoke workpiece 1 is located between the first inclined baffle 10 and the second inclined baffle 11. A sleeve 12 is fixed to the right end of the second frame 9. A lead screw 13 is internally threaded onto the sleeve 12. A first bracket 14 is fixed to the lower mold plate 6. The lead screw 13 is rotatably connected to the first bracket 14.

[0019] The lower template 6 is provided with guide rails 15 located on the front and rear sides of the sleeve 12. One end of the guide rail 15 is fixedly connected to the first bracket 14. The lower template 6 is fixed with a second bracket 16 fixedly connected to the other end of the guide rail 15. Horizontal plates are fixed on the front and rear sides of the sleeve 12 and slide along the guide rail 15 in the left and right direction.

[0020] To facilitate the rotation of the lead screw 13, a turntable 17 located on the right side of the first bracket 14 is coaxially fixed to the lead screw 13.

[0021] To facilitate the guide rod 5 entering the interior of the cylinder 7, a conical ring 18 is fixed on the upper end face of the cylinder 7.

[0022] The lower template 6 is provided with punching holes 19 corresponding to the punch 4. The lower template 6 is provided with a collection cavity 20 located below the punching holes 19. The punching holes 19 and the collection cavity 20 are connected.

[0023] A spring 21 is installed at the bottom of the cylinder 7, and a buffer plate 22 is connected to the upper end of the spring 21. The buffer plate 22 slides up and down inside the cylinder 7.

[0024] In use, the spoke workpiece 1 is first placed on the lower template 6, and the turntable 17 is rotated. The turntable 17 drives the lead screw 13 to rotate coaxially. The lead screw 13 is threadedly connected to the sleeve 12. The sleeve 12 drives the horizontal plate to slide to the left along the guide rail 15. The sleeve 12 drives the second frame 9 to slide to the left. The second frame 9 drives the second inclined baffle 11 to move the spoke workpiece 1 to the left. Since the position of the first inclined baffle 10 remains unchanged, when the first inclined baffle 10 and the second inclined baffle 11 simultaneously clamp the spoke workpiece 1, the turntable 17 is stopped from rotating. The first inclined baffle 10 and the second inclined baffle 11 are both made of rubber, which not only has a good clamping effect, but also protects the spoke workpiece 1 and prevents wear on the spoke workpiece 1. The threaded connection has self-locking properties and good stability.

[0025] Subsequently, the upper mold assembly moves downward, and the guide rod 5 first enters the conical ring 18. The conical ring 18 increases the contact area of ​​the guide rod 5, making it easier for the guide rod 5 to enter the cylinder 7 through the conical ring 18. The guide rods 5 around the upper mold plate 2 are all inserted into the corresponding cylinders 7 to ensure the stability of the punch 4's up and down movement. The guide rod 5 drives the buffer plate 22 to move downward in the cylinder 7, thereby squeezing the spring 21, which has a certain buffering effect on the guide rod 5 and is conducive to the feeding of the punch 4. As the upper mold plate 2 moves downward, the punch 4 contacts the spoke workpiece 1, and the punch 4 begins to punch the spoke workpiece 1. The punched material that detaches from the punch 4 falls into the collection chamber 20 through the punching hole 19. The punched material in the collection chamber 20 is cleaned periodically.

[0026] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
