PURPOSE:To reduce an arrangement space of a machine, and to execute working of a large plate material by providing each percussion device in a position on a diagonal line which has been separated by a distance corresponding to a diameter of a locus circle where a punch and a die have been placed, on a turret. CONSTITUTION:A ram 31 and a ram 33 are supported by the upper frame 9 so that they can move freely upward and downward, and also, provided in a position on a diagonal line which has been separated by a distance corresponding to a diameter of a locus circle, on the upper part of a track path of an arranged locus circle drawn by plural punches 15 which have been supported by the upper turret 17. Also, to the respective lower face of the rams 31, 33, percussion pieces 27, 29 for hitting the punches 15 are installed. Moreover, by setting the metallic dies of the same punch 15 and a die 21 on a diagonal line to a station of a turret device 25, two pieces can be worked simultaneously by a product working pitch.
