[0027] In summary, the working principle and process of this multi-station stamping die for micro-battery casing are as follows: First, the die is installed and fixed on the stamping equipment. The stamping equipment is then started, causing the top seat 15 to move the top plate 16 downwards. As the top plate 16 moves downwards, the upper stamping block 17 and the lower stamping block 5 close, completing the micro-battery casing forming process. Simultaneously, the upper pressure block 14 on the top plate 16 presses down on the lower pressure block 13 of the slider 9, pushing the slider 9 downwards along the slide groove. Through the connecting rod 12, the pusher plate 8 moves to directly below the discharge cylinder 21. After stamping, the formed workpiece falls directly onto the pusher plate 8 through the discharge port 6 and the discharge cylinder 21. The stamping equipment drives the upper die mechanism to move upwards and reset. The pressure of the upper pressure block 14 on the lower pressure block 13 disappears, and the slider 9 slides upwards and resets under the elastic force of the spring 11. Through the connecting rod 12, the pusher plate 8 resets synchronously. During the reset process of the pusher plate 8, the finished product above it... The workpiece detaches from the pusher plate 8 and falls into the slide groove of the slide block 7 below the discharge cylinder 21, completing the first workpiece entry. Then, the second round of stamping is started, repeating the actions of mold closing and stamping, the pusher plate 8 moving below the discharge cylinder 21, and the finished product falling above the pusher plate 8. At the same time, during this pressing process, when the upper pressure block 14 pushes the slider 9 to drive the pusher plate 8 to slide, the pusher plate 8 will push the previous finished workpiece left in the slide groove to the slide plate 22, and then discharge it from the mold through the slide plate 22. After the second round of stamping is completed, the upper mold mechanism resets, and the pusher plate 8 brings back the current finished workpiece, which falls into the slide groove during the reset. During the third round of processing, the pusher plate 8 pushes the previous workpiece in the slide groove again, and the new finished product falls onto the pusher plate 8 simultaneously. This cycle is repeated to realize the continuous automated processing of the micro battery shell. The entire process does not require an additional power source. Through the coordinated movement of the upper mold mechanism and the reset of the spring 11, the processing efficiency and quality are guaranteed.

[0028] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent.
