ABSTRACT:
A press brake adapted to apply bending on metal blanks in the form of a sheet or plate includes a plurality of die assemblies located on a die holder at intervals of a predetermined distance in the direction perpendicular to the logitudinal direction of a bed of the press brake. The die holder is mounted on the bed movably in the direction perpendicular to the longitudinal direction of the bed. Each of the die assemblies is provided with an upper die and a lower die which are associated with each other and movable vertically towards and away from each other. The press brake further includes a pair of front and inside stoppers located on the front side and the inner side of the press brake body, respectively, so as to be movable freely towards and away from each other and pass through a space between the upper and lower dies.
