After the upper die body 201 moves upward, the first electromagnet 2026 is de - energized to separate the upper die body 201 from the movable ring plate 104. At the same time, the fixed rod 2036 is energized to make the top block 2033 move downward, generating a thrust on the top of the formed inner cylinder and pushing the formed inner cylinder out of the upper die body 201, which is convenient for blanking.

[0029] Working principle: During operation, first place the sheet metal for stamping on the top of the lower die body 102. Subsequently, the upper die body 201 moves downward and sleeves on the outside of the lower die body 102 until the bottom wall of the upper die body 201 is in close contact with the top wall of the movable ring plate 104, forming a forming cavity between the inner wall of the upper die body 201, the top wall of the movable ring plate 104, and the outer wall of the lower die body 102, and stamping the sheet metal into a cylindrical shape;

[0030] Subsequently, the first electromagnet 2026 is energized to generate a repulsive force on the first magnetic block 2025, pushing the latch rod 2023 into the card slot 106 on the side wall of the movable ring plate 104. Subsequently, the upper die body 201 moves upward to drive the movable ring plate 104 upward. Since the bottom wall of the formed inner cylinder is located above the movable ring plate 104, the formed inner cylinder can be directly taken out of the lower die body 102;

[0031] Subsequently, the first electromagnet 2026 is powered off, causing the latch rod 2023 to leave the card slot 106, separating the movable ring plate 104 from the upper die body 201, and opening the bottom of the upper die body 201;

[0032] Then, the second electromagnet 2039 is energized to generate a repulsive force on the second magnetic block 2038, pushing the top block 2033 downward to generate a thrust on the formed inner cylinder, thereby pushing the formed inner cylinder out of the upper die body 201 for convenient discharging.
