At this time, the material strip is located between the carrier plate 136 and the punch. Then the No. 1 electric cylinder 135 drives the punch to move down to cut the material strip. When the punch is reset after cutting, the No. 1 linear module A133 drives the No. 1 slide to move out of the No. 1 support A134, so that the No. 1 transport mechanism 14 can transport the cut material strip on the carrier plate 136.
