Then, hydraulic cylinder 2 12 is started to drive the upper die 7 to move as a whole in the direction of the lower die 2. The lower surfaces of the punching block 8 and the bending block 9 are in contact with the upper surface of the connecting steel strip at the same time, and push the connecting steel strip to the surface of the punching platform 21.

[0048] At this time, the telescopic cylinder 5 is used to drive the support seat 4 to slide in the direction away from the hole-pressing platform 21, and the support plate 2 41 is separated from the connecting steel belt. While the support seat 4 slides, it will drive the pull rope 61 to drive the support bar 6 to move downward, and then the hydraulic cylinder 10 is used to drive the connecting plate 11 to move.
