[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] In this invention, during the stamping process, the lower die is subjected to pressure and descends. This descent causes the telescopic rod to compress the spring and descend. Simultaneously, the telescopic rod lowers the support plate, which in turn lowers the connecting plate via the connecting rod. The descending connecting plate then lowers the piston, drawing air from inside the sealing cylinder. When the lower die reaches a certain depth, it stops descending, and stamping begins. After stamping, the stamping equipment resets, and the telescopic rod, under the action of the spring, resets, causing the lower die to eject and reset. Simultaneously, the telescopic rod resets, causing the piston to move upwards, blowing the air from inside the sealing cylinder through the blower pipe. This blows the ejected stamped part into the collection box, completing the post-stamping collection.

[0016] This solves the problem that copper sheets may adhere to the inside of the stamping die after stamping, requiring manual unloading, which is cumbersome and poses safety hazards. Attached Figure Description
