Referring to fig. 7-11, optionally, the first bending structure and the second bending structure each include a preliminary bending structure 4 and a complete bending structure 3. The preliminary bending structure 4 is used for preliminarily bending the unformed middle ring 15 of the primary and secondary hinges. The complete bending structure 3 is used for completely bending the unformed middle ring 15 of the primary-bent primary-secondary hinge, so that the middle ring 15 is completely formed.

Referring to fig. 7-9, optionally, the preliminary bending structures 4 each include a first base 42 and a punch 41. The first base 42 is provided with a first groove 421, and one end of the first groove 421 is provided with an arc 422. The punch 41 is disposed opposite to the first groove 421, the bottom end of the punch 41 is provided with a fillet 411 disposed corresponding to the arc 422, and the middle ring 15 of the primary and secondary hinges is disposed on the first groove 421. When the centering ring 15 is preliminarily bent, the punch 41 moves towards the direction close to the first groove 421 to punch the unformed middle ring 15 arranged on the first groove 421, so that the unformed middle ring 15 forms a middle ring 15 groove, and one end of the middle ring 15 groove forms the circular arc-shaped bending portion 152, so that the unformed middle ring 15 is preliminarily bent, and the completely bending structure 3 further completely bends the unformed middle ring 15.

Optionally, all be provided with two sets of preliminary bending structures 4 in each punching press module to in the while carry out preliminary bending to the zhonghuan 15 of the female flabellum 11 of same group primary and secondary hinge and son flabellum 12, raise the efficiency.

The first preliminary bending station 531 and the second preliminary bending station 631 are both provided with preliminary bending structures 4. A full bending structure 3 is provided at both the first full bending station 532 and the second full bending station 632.

Referring to fig. 10 and 11, optionally, the fully-bent structure 3 includes a punch 31 and a stopper 32. The punch block 31 is provided with a second groove 311, and the second groove 311 is in a semi-arc shape. The stop piece 32 is arranged on one side of the punch block 31, a stop groove 321 is formed in the stop piece 32, the hinge body of the primary-secondary hinge extends into the stop groove 321 and abuts against the bottom of the stop groove 321, and the bent portion 152 abuts against the second groove 311. The punch block 31 is in transmission connection with the punch block 31, and is used for driving the punch block 31 to move towards the direction close to the stop member 32 so as to punch the bent part 152 to form the formed middle ring 15 in a curling manner.
