Disclosed are a method and device for alternately cutting off materials by back-and-forth movement of multiple vehicles. The device is specifically a cut-off machine for alternately cutting off materials by back-and-forth movement of multiple vehicles. The cut-off machine is at least provided with two cutter vehicles (1, 2), wherein these vehicles are installed on tracks (4) parallel to materials; the tracks are arranged around the materials (3) side by side; each vehicle moves back and forth in accordance with a set sequence; cutters (7, 9) on the vehicles alternately cut off the materials in accordance with a set length; and the larger the number of vehicles is, the longer the stroke of each vehicle can be set, so that the cutters have more time to cut off the materials, and therefore, the cut-off machine can be adapted to a higher material forming speed in a production line. |
