Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] Please see the appendix Figure 1-3 A punching and cutting device for thin short shaft parts includes a worktable 1, a punching device, a fixing device, a blanking device, an arc-shaped support plate 2, and a feeding device. The punching device is set on the worktable 1, the fixing device is set on the punching device, the blanking device is set on the side of the worktable 1 away from the punching device, the feeding device is set on the side of the worktable 1 close to the blanking device, and the arc-shaped support plate 2 is set on the worktable 1 directly below the blanking device.

[0021] The stamping device includes a first support plate 3, a first cylinder 4, a connecting frame 5, and a stamping knife 6. The first support plate 3 is set on the worktable 1, the first cylinder 4 is set on the upper side of the first support plate 3, the connecting frame 5 is set on the output end of the first cylinder 4, and the stamping knife 6 is set on the connecting frame 5.

[0022] Using the above technical solution, the worktable 1 serves as the foundation of the entire processing device, supporting various parts such as the stamping device, fixing device, unloading device, arc-shaped support plate 2, and feeding device. The stamping device is set on the worktable 1 and fixed by the first support plate 3. The first cylinder 4 serves as the power source and drives the stamping knife 6 to move up and down through the connecting frame 5 to realize the punching processing of thin and short shaft parts.

[0023] When the slender shaft part is placed in the unloading device and unloaded onto the arc-shaped support plate 2, it is ready for punching. The first cylinder 4 is activated, driving the connecting frame 5 and the punching knife 6 to move downward. At the same time, the telescopic rod 7 also moves downward. The fixing block 8 at its bottom presses down and fixes the slender shaft part on the arc-shaped support plate 2 to ensure that the part will not move or deform during the punching process. After the punching knife 6 reaches the predetermined position, it punches the slender shaft part.

[0024] In some embodiments, the fixing device includes a telescopic rod 7 and a fixing block 8, the telescopic rod 7 being disposed on the connecting frame 5, and the fixing block 8 being disposed at the bottom of the telescopic rod 7.

[0025] In some embodiments, the feeding device includes a feeding box 9, a quarter feeding cylinder 10, a ratchet 11, a ratchet rack 12, and a connecting rod 13. The feeding box 9 is disposed on the workbench 1, the quarter feeding cylinder 10 is rotatably disposed on the lower side of the feeding box 9, the ratchet 11 is disposed on the quarter feeding cylinder 10, the connecting rod 13 is disposed on the telescopic rod 7, the ratchet rack 12 is disposed on the connecting rod 13, and the ratchet 11 and the ratchet rack 12 are in contact with each other.

[0026] Using the above technical solution, during the downward movement of the stamping cutter 6 and the fixing block 8, the connecting rod 13 and the ratchet 12 driven by the telescopic rod 7 also move downward. At this time, the ratchet 12 and the ratchet gear 11 do not contact or mesh, allowing the quarter-sized unloading cylinder 10 to remain in its original position. When the stamping cutter 6 and the fixing block 8 move upward, the connecting rod 13 and the ratchet 12 also move upward. At this time, the ratchet 12 and the ratchet gear 11 contact and mesh, driving the quarter-sized unloading cylinder 10 to rotate a quarter turn, dropping the next thin short shaft part onto the arc-shaped support plate 2.

[0027] In some embodiments, the feeding device includes a second cylinder 14 and a push rod 15. The second cylinder 14 is disposed on the side wall of the worktable 1, and the push rod 15 is disposed on the output end of the second cylinder 14.

[0028] After the punching process is completed, the second cylinder 14 is started, which drives the push rod 15 to move along the direction of the arc-shaped support plate 2. The push rod 15 pushes the short shaft part that has just been cut to move along the arc-shaped support plate 2 towards the stamping knife 6. At the same time, the short shaft part will push the short shaft part that has been stamped to the collection box 17.

[0029] In some embodiments, a guide plate 16 is provided on the worktable 1, and the ratchet 12 is slidably connected to the guide plate 16. The guide plate 16 is provided on the worktable 1 to guide the up and down movement of the ratchet 12 and ensure its smooth operation.

[0030] In some embodiments, a collection box 17 is provided on the side of the worktable 1 near the stamping knife 6. The collection box 17 is provided on the side of the worktable 1 near the stamping knife 6 to collect the short and thin shaft parts that have been stamped, so as to facilitate subsequent sorting and processing.

[0031] Working principle:

[0032] The short, thin shaft part is placed in the feed box 9 and fed onto the arc-shaped support plate 2. When the first cylinder 4 moves the stamping cutter 6, the telescopic rod 7, and the fixing plate downwards, the fixing plate presses down and fixes the short, thin shaft part on the arc-shaped support plate 2. Then, the stamping cutter 6 cuts it off. Simultaneously, the telescopic rod 7 moves downwards, driving the connecting rod 13 and the ratchet rack 12 downwards. At this time, the ratchet rack 12 and the ratchet gear 11 are not engaged. When the first cylinder 4 moves the stamping cutter 6, the telescopic rod 7, and the fixing plate upwards, the connecting rod... 13 and ratchet 12 move upwards, at which point ratchet 12 and ratchet gear 11 mesh, causing the quarter-section feed cylinder 10 to rotate a quarter turn, thereby feeding a thin short shaft part onto the arc-shaped support plate 2. The second cylinder 14 is controlled to move the working belt push rod 15, which pushes the freshly fed thin short shaft part along the arc-shaped support plate 2 toward the stamping knife 6. At the same time, the freshly fed thin short shaft part will push out the already stamped thin short shaft part. This process is repeated to continuously process the thin short shaft part.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
