[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1 to 3 The present invention provides the following technical solution: like Figure 1 and Figure 2As shown, a high-efficiency punching and shearing die for shell buttons includes an upper die and a lower die mounted on a frame. The lower die includes a first fixed base 1, a first mounting cylinder 2 fixedly connected to the top of the first fixed base 1, a first slider 3 slidably connected inside the first mounting cylinder 2, a first push rod 4 fixedly connected to the top of the first slider 3, the upper end of the first push rod 4 extending upward through the top of the first mounting cylinder 2, two symmetrically distributed drive sliders 5 fixedly connected to the outside of the first push rod 4, and a positioning sleeve 6 rotatably connected to the top of the first mounting cylinder 2. The positioning sleeve 6 has two drive grooves 7 arranged in a spiral structure on its outside.

[0021] like Figure 2 and Figure 3 As shown, the positioning sleeve 6 is sleeved on the outside of the first top rod 4, and the driving slider 5 is slidably connected to the inside of the driving groove 7. The top of the positioning sleeve 6 is provided with a serrated structure. The bottom of the first mounting cylinder 2 is fixedly connected to the first top block 8, and the bottom of the first top block 8 and the first slider 3 are aligned. The first mounting cylinder 2 is provided with a first spring 9, which is sleeved on the outside of the first top block 8, and the upper end of the first spring 9 abuts against the bottom of the first slider 3. The top of the first mounting cylinder 2 is provided with a mounting groove 10, and the bottom outside of the positioning sleeve 6 is provided with a flange. The bottom flange of the positioning sleeve 6 is rotatably connected to the inside of the mounting groove 10.

[0022] First, the shell is placed on top of the first push rod 4. At this time, the lower pressure block 26 begins to move downward under the external driving force, causing the upper mold to move downward as a whole. The downward pressure of the upper mold, together with the first push rod 4, clamps the shell. The shell is subjected to vertical downward pressure. As the upper mold continues to press down, the shell pushes the first push rod 4 downward. The downward movement of the first push rod 4 causes the first slider 3 to slide axially inside the first mounting cylinder 2. The sliding of the first slider 3 compresses the first spring 9. The first spring 9 is sleeved on the outside of the first push block 8, and the upper end of the first spring 9 abuts against the bottom of the first slider 3. Therefore, the first spring 9 is compressed and stores elastic potential energy.

[0023] As the first push rod 4 slides downward, the drive slider 5, which is fixedly connected to the outside of the first push rod 4, slides inside the drive groove 7 of the positioning sleeve 6. The drive groove 7 is distributed in a spiral structure. The drive slider 5 slides along the spiral trajectory of the drive groove 7, applying a tangential force to the wall of the drive groove 7. Since the positioning sleeve 6 is rotatably connected to the mounting groove 10 at the top of the first mounting cylinder 2 through its bottom flange, the positioning sleeve 6 can rotate around its axis. Therefore, the sliding of the drive slider 5 is converted into the rotational motion of the positioning sleeve 6. As the first push rod 4 continues to move downward, the shell contacts the top of the positioning sleeve 6. The serrated structure at the top of the positioning sleeve 6 engages with the surface of the shell, providing anti-slip and positioning functions. When the upper mold continues to press down and cut the shell, the rotational motion of the positioning sleeve 6 helps the shell remain stable during the cutting process, preventing slippage and ensuring cutting accuracy. After the cutting is completed, the upper mold retracts upward, the first spring 9 releases elastic potential energy, pushes the first slider 3 to slide upward, thereby driving the first push rod 4 to move upward and popping the cut button blank out of the positioning sleeve 6.

[0024] Example 2: Based on Example 1, please refer to... Figures 4 to 6 as well as Figure 1 The following structure was also disclosed: like Figure 4 As shown, the upper mold includes a second fixed base 11, a second mounting cylinder 12 is fixedly connected to one bottom end of the second fixed base 11, a second slider 13 is slidably connected inside the second mounting cylinder 12, a second push rod 14 is fixedly connected to the bottom of the second slider 13, and the lower end of the second push rod 14 extends downward through the bottom of the second fixed base 11.

[0025] like Figure 5 As shown, a cutting sleeve 15 is rotatably connected to the lower end of the second mounting sleeve 12. The outer diameter of the cutting sleeve 15 is the same as the inner diameter of the positioning sleeve 6, and the cutting sleeve 15 and the positioning sleeve 6 are aligned. The bottom of the cutting sleeve 15 is provided with a serrated structure. A gear ring 16 is fixedly connected to the outer side of the upper end of the cutting sleeve 15, and a mounting ring 17 is fixedly connected to the outer side of the top of the cutting sleeve 15. A motor 22 is fixedly connected to the bottom end of the second fixing seat 11 away from the second mounting sleeve 12. A drive gear 23 is fixedly connected to the output end of the motor 22, and the drive gear 23 meshes with the gear ring 16.

[0026] like Figure 5 and Figure 6As shown, a second top block 18 is fixedly connected to the top of the second mounting cylinder 12, and the second top block 18 is aligned with the second slider 13. A second spring 19 is provided inside the second mounting cylinder 12. The second spring 19 is sleeved on the outside of the second top block 18, and the lower end of the second spring 19 abuts against the top of the second slider 13. A mounting sleeve 20 is fixedly connected to the lower end of the second mounting cylinder 12. Annularly distributed ball bearings 21 are installed inside the mounting sleeve 20. The ball bearings 21 are double-layered. A mounting ring 17 is rotatably connected inside the mounting sleeve 20, and the double-layered ball bearings 21 are installed at the upper and lower ends of the mounting ring 17.

[0027] like Figure 1 As shown, the frame includes a base 24, a column 25 is fixedly connected to the top of the base 24, a lower pressure block 26 is slidably connected to one side of the column 25, the lower mold is installed on the top of the base 24, and the upper mold is installed on the bottom of the lower pressure block 26.

[0028] When the device is in use, the operator places the shell on top of the first push rod 4. The lower pressure block 26 moves downward, causing the upper mold to descend as a whole. The second push rod 14 of the upper mold first contacts the shell and together with the first push rod 4 forms a clamping mechanism to fix the shell. As the lower pressure block 26 continues to press down, the shell is subjected to pressure, pushing the first push rod 4 to move downward. The first push rod 4 drives the first slider 3 to slide inside the first mounting cylinder 2, compressing the first spring 9. At the same time, it drives the slider 5 to slide in the drive groove 7, driving the positioning sleeve 6 to rotate.

[0029] Simultaneously, the second push rod 14 is subjected to the reaction force of the shell, pushing the second slider 13 to slide upward inside the second mounting cylinder 12. The sliding of the second slider 13 compresses the second spring 19, which is sleeved on the outside of the second push block 18. The lower end of the second spring 19 abuts against the top of the second slider 13, thus compressing the second spring 19 and storing elastic potential energy. The upper mold continues to descend, and the cutting sleeve 15 contacts the shell. The cutting sleeve 15 is rotatably connected to the inside of the mounting sleeve 20 through the mounting ring 17. The mounting sleeve 20 is fixed to the lower end of the second mounting cylinder 12. The mounting sleeve 20 is provided with double-layered ball bearings 21 inside, which support the upper and lower ends of the mounting ring 17, enabling the cutting sleeve 15 to rotate with low friction. The motor 22 starts, and the drive gear 23 rotates. The drive gear 23 meshes with the gear ring 16, which is fixed to the outer side of the upper end of the cutting sleeve 15. Therefore, the cutting sleeve 15 rotates. The bottom of the cutting sleeve 15 is provided with a serrated structure, which cooperates with the serrated structure at the top of the positioning sleeve 6 to perform rotational cutting of the shell.

[0030] During the cutting process, the rotation of the positioning sleeve 6 and the rotation of the cutting sleeve 15 work together to ensure that the shell is stably positioned and accurately cut. The cut button blank falls into the positioning sleeve 6. After the cutting is completed, the lower pressure block 26 moves upward, the upper mold retracts, the second spring 19 releases elastic potential energy, pushes the second slider 13 to slide downward, and drives the second push rod 14 to move downward and separate from the shell. At the same time, the first spring 9 releases elastic potential energy, pushes the first slider 3 to slide upward, and drives the first push rod 4 to move upward, pushing the button blank out of the positioning sleeve 6, thus completing the blank removal process.
