[0029] Specific Embodiment 2. Please refer to Figures 1-5 , on the basis of Specific Embodiment 1, the pressing die member includes a pressing plate 12, the pressing plate 12 is fixedly connected to the free end of the cylinder 3, and spring rods 13 are fixedly connected to the four peripheries of the bottom of the pressing plate 12. One end of the spring rod 13 is fixedly connected to a pressing die 14. A support block 15 is fixedly connected to the bottom of the inner cavity of the housing 1. The top of the support block 15 is fixedly connected to the bottom of the placing table 2. One end of the rotating shaft 4 is fixedly connected to a gear 16. The gear 16 meshes with the toothed plate 7. One side of the top of the inner cavity of the housing 1 is fixedly connected to a support plate 17.

The sliding sleeve 11 plays a limiting role for the cross plate 6.

[0032] The working principle of the present utility model is as follows: When it is necessary to bend the aluminum-reinforced circuit board, first start the motor 9.

The sliding sleeve 11 drives the air cylinder 3 and its free-end structure to move towards the rear end of the inner cavity of the housing 1. Then, place the circuit board to be bent on the surface of the placement table 2, and start the motor 9 again to move the air cylinder 3 to the center of the inner cavity of the housing 1.

[0033] When the bottom of the pressing die 14 is in contact with the center of the circuit board, the air cylinder 3 can be opened through the controller. The air cylinder 3 drives the pressing plate 12 to move. The pressing plate 12 drives the spring rod 13 to move. The spring rod 13 drives the pressing die 14 to move. The pressing die 14 is in contact with the top of the circuit board. When the air cylinder 3 continues to work, it will buffer the stress on the surface of the circuit board through the spring rod 13. The air cylinder 3 continues to work to squeeze the toothed plate 7. The toothed plate 7 drives the gear 16 to rotate. The gear 16 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the bending plate 5 to rotate. The bending plate 5 bends the edge of the circuit board.

[0034] When the bending work is completed, the pressing die 14 can be separated from the surface of the circuit board through the air cylinder 3. When the pressing die 14 moves, the toothed plate 7 can move upward through the reset spring 8 and the cross plate 6. The toothed plate 7 drives the gear 16 to reverse, thereby resetting the bending plate 5. Finally, start the motor 9 through the controller to move the air cylinder 3 away and take out the bent circuit board.
