Of course, in other embodiments, the first driver 442 can also be a motor component with a transmission unit.
[0036] The punching die 41 includes a mounting plate 411, a cutting die 412 mounted on the mounting plate 411, and a second driver 413 for driving the mounting plate 411 to rise and fall. Specifically, the second driver 413 is a second cylinder. The mounting plate 411 is provided with a laser through hole 414.

The mounting plate 411 is assembled to the mounting bracket 45 in a liftable manner through a second group of guide columns. The second driver 413 is used to drive the mounting plate 411 to rise and fall, so as to drive the cutting die 412 to rise and fall, press the cutting die 412 downward, and insert the positioning hole of the second steel strip 2 into the positioning pin 43 to ensure that the steel sheet welding point of the first steel strip 1 is aligned with the corresponding steel sheet welding point of the second steel strip 2, and the steel sheet of the second steel strip 2 is simultaneously pressed and punched.
