Abstract:
A mold for a press brake includes an upper mold that is mountable on an upper table and a lower mold mountable on a lower table in a press brake. The upper mold and the lower mold vertically face each other and have respective pressurizing surfaces. The respective pressurizing surfaces are superposed with each other in a pressing direction so as to define a wedge shaped recess between the respective pressurizing surfaces. The respective pressurizing surfaces are configured to pressurize a workpiece positioned between the respective pressurizing surfaces. Further, one of the pressurizing surfaces is formed as a level surface and the other is formed as an inclined surface. The upper mold includes a V-shaped workpiece bending portion that can freely enter into a bending groove provided in the lower mold, and the respective pressurizing surfaces are positioned outside of the bending groove of the lower mold.
