加工装置。 A steel plate to be bent is placed over two receiving rolls arranged at a required interval, and the pressurized steel plate is brought into contact with the steel plate to be bent at an intermediate position between the two receiving rolls. In a steel plate bending apparatus in which a bending load is applied to a steel plate to be bent by a die, an annular groove of a required width is provided on the outer periphery of each receiving mold roll where the front and rear ends of the steel plate to be bent are respectively located. A mantle tube having a bending rigidity smaller than that of the steel plate to be bent is fitted onto the outer periphery of each receiving roll so as to form an annular groove at both ends of each receiving roll. Steel plate bending equipment.
