摘要： A press-forming apparatus (20) is an apparatus for producing a press-formed product (10) having a hat-shaped cross section that has an external shape that curves in an L shape along a longitudinal direction in a planar view, and includes a punch (31), a first blank holder (32), a second blank holder (33), a preceding portion (54), a second die (53) and a pad (41). When pushing the punch (31) into a die (50) to form a metal plate (70) into the press-formed product (10), a first guide face (50c) of the preceding portion (54) precedes a second guide face (50d) of the second die (53), and thereafter sliding of the first blank holder (32) and the preceding portion (54) relative to the punch (31) is restricted and pushing of the punch (31) into the die (50) is continued in the restricted state to form the press-formed product (10). By this means, the press-formed product (10) in which cracks and wrinkles are reduced is obtained.

摘要： There is provided a method of manufacturing a cylindrical container using a metal sheet on at least one surface of which the metal is exposed. The method includes: obtaining a blank having a hexagonal shape from the metal sheet; and processing the blank into a cylindrical shape by pressing a central part of the blank with a punch in a state in which a peripheral part of the blank is clamped between a die for drawing process and a blank holder. The method is characterized by the following features. At least one of the die for drawing process and the blank holder has a groove-formed area at a portion of a surface thereof. The portion corresponds to a side of the blank. The groove-formed area is formed with a plurality of grooves along the circumferential direction. The blank is processed into the cylindrical shape by clamping the peripheral part of the blank between the die for drawing process and the blank holder so that the surface of the blank on which the metal is exposed is in a state of facing the groove-formed area and the side of the blank is in a position that corresponds to the groove-formed area.
