And starting the first electric push rod 3 on the mounting plates 2 at the two sides, and pushing the first die 4 and the second die 7 to move oppositely by the force of the push rod. In this process, the insert plate 8 is precisely inserted into the slot 6, so that the first die 4 and the second die 7 are tightly sealed together. And when the first die 4 moves, the second inclined block 16 is driven to synchronously move. When the second inclined block 16 contacts with the first inclined block 15, the first inclined block 15 is pressed to move downwards, so that the second spring 14 in the baffle plate 9 is compressed. When the second inclined block 16 moves to the other side, the spring II 14 ejects the first inclined block 15 by virtue of elasticity, so that the second inclined block is blocked on the other side of the second inclined block 16, and a workpiece to be machined is placed in the inner cavity 5 between the first die 4 and the second die 7. After the processing and forming, the first electric push rod 3 is reversely started to separate the first die 4 from the second die 7. When the first die 4 moves, the second inclined block 16 pushes the first inclined block 15 outwards, the first inclined block 15 drives the baffle plate 9 to slide outwards in the chute 10, the telescopic rod 12 and the first spring 13 are compressed, the blanking hole 11 is exposed, and the processed bolt falls off. After the blanking is completed, the first spring 13 resets the baffle plate 9 by virtue of elasticity, and is ready for the next processing.

In the press forming stage of the bolt, the second electric push rod 19 at the top of the bracket 18 is started. After the second electric push rod 19 is started, the upper pressing plate 23 on the connecting plate 20 is driven to move downwards. As the upper platen 23 moves down gradually, it presses the bolts until the bolts are formed. In the pressing process, the upper pressing plate 23 can simultaneously press the third spring 22 and the damping rod 24, and the damping rod 24 can effectively buffer the downward pressure of the upper pressing plate 23 by virtue of the unique damping force of the third spring 22 and the rebound resilience of the third spring 22. The buffering effect can smoothly slow down impact energy generated in the stamping process, so that the stamping action is more stable. In this way, the stability of the device is further improved, and the forming quality of the bolt is also ensured.
