Thus, the two metal strips move to the cutting through hole 313, the pressing block 32 presses one end of the metal sheet, the upper pressing die 33 and the lower cutter device 34 clamp the metal sheet and drive the metal sheet to move up and down, the suction nozzle 332 sucks the metal sheet, and the cutting and sucking processes of the metal sheet are completed.

Specifically, the upper pressing driving device 35 includes a connecting rod 351 connecting the two upper pressing dies 33 and a vertical first cylinder 352 fixed to the connecting rod 351, and the first cylinder 352 drives the two upper pressing dies 33 to move up and down repeatedly in synchronization.

Specifically, the material pressing block 32 includes a material passing block 321 and a material pressing cutter 322 which are correspondingly arranged. The lower cutter device 34 often rubs against the pressing cutter 322 when moving upward, and the material of the pressing cutter 322 is inevitably required to have higher wear resistance, while the material passing block 321 is not required to have higher wear resistance, and the material passing block 321 and the pressing cutter 322 can be made of different materials to save the manufacturing cost.

Specifically, the lower cutter device 34 includes a lower top block 341 and a lower cutter 342, which are correspondingly disposed, two vertical positioning pins 343 are disposed on the lower top block 341, and the positioning pins 343 are disposed corresponding to the positioning holes 41 on the metal material tape 40.
