The utility model discloses the theory of operation: when the die is closed downwards, the upper pressing block 9 moves downwards under the driving of the die template, so as to drive the product 8 to move downwards, when the product 8 contacts the lower pressing block 7 downwards, the lower pressing block 7 moves downwards relative to the female die fixing block 4 under the supporting action of the lower fixing block strong spring 5, and the upper pressing block 9 moves upwards relative to the punch fixing block 13. Because the elasticity and the compression amount of the lower fixed block strong spring 5 and the upper fixed block strong spring 11 are consistent, the movement of the puncture punch 17 and the puncture mould core 18 relative to the product 8 is ensured to be synchronous.

Then, the die template continues to move downwards, the upper material pressing block 9 pushes the upper force transmission pin 12 to contact the upper spring sleeve 14, the lower material pressing block 7 moves downwards to contact the lower force transmission pin 19 and further to contact the lower spring sleeve 3, the upper spring sleeve 14 moves downwards relative to the product 8 under the supporting action of the upper template strong spring 15 and the lower template strong spring 2, and the lower spring sleeve 3 moves upwards relative to the product 8. Because the elasticity and the compression amount of the lower template strong spring 2 and the upper template strong spring 15 are consistent, the movement of the lower spring sleeve 3 and the upper spring sleeve 14 is synchronous, and further, the movement of the puncture punch 17 and the puncture mould core 18 relative to the product 8 is continuously ensured to be synchronous.

In the downward die closing process of the die, the movement of the piercing punch 17 and the piercing die core 18 relative to the product 8 is synchronous all the time, so that the distance between the piercing die core 18 and the product 8 is consistent with the distance between the piercing punch 17 and the product 8, and the purpose of synchronous piercing is achieved.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
