[0043] When the workpiece needs to be cut, the operator places the workpiece on the conveying part 1 and manually pushes the workpiece toward the cutting part 2 until the front end of the workpiece abuts against the limit plate 254. The front clamping and fixing unit 231 and the rear clamping and fixing unit 232 clamp the workpiece. After clamping, the first electric cylinder 222 drives the cutting machine 221 to press down to cut the workpiece. After cutting, the first electric cylinder 222 drives the cutting machine 221 to lift and reset. The front clamping and fixing unit 231 and the rear clamping and fixing unit 232 release the clamping of the workpiece. At this time, the cut workpiece falls and slides out along the slide 24, completing a round of cutting. The above actions are repeated to achieve continuous cutting of the workpiece.
