    摘要： The invention relates to a forming device for forming a bend in a corrugation. The forming device comprises: a bottom frame (4) having a planar mounting surface (6) for receiving a sheet metal plate having a corrugation projecting in relation to a planar portion of the sheet metal plate, a projecting counter-form (5) placed on the mounting surface and intended to be accommodated in the corrugation, wherein the projecting counter-form has a stationary portion (7) and a movable portion (8) that is hinged, in relation to the stationary portion, around an axis perpendicular to the mounting surface, a top frame (34) placed above the bottom frame, a press configured to lower the top frame towards the bottom frame, and a hollow upper die supported by the top frame between the top frame (34) and the bottom frame (4). The hollow upper die (36, 37) is arranged above the movable portion of the projecting counter-form.

    摘要： Projection row (2) and recess row (3) are alternately and successively formed in a direction (Y-direction) perpendicular to a direction (X-direction) of their rows, thereby forming a corrugated cross-sectional shape of a cross-sectional wave shape. Between projection row (2) and recess row (3), there is provided inclined wall surface (4) having a wave shape in plan view. Each of projection row (2) and recess row (3) has a shape in a cross-section along X-direction that is formed into a corrugated cross-sectional shape of a wave shape. Pitch and height difference between valley portion (5) and crest portion (6) in the corrugated cross-sectional shape along this X-direction are smaller, as compared with a relationship between projection row (2) and recess row (3) in the corrugated cross-sectional shape along Y-direction. The corrugated metal plate of such shape has advantages that machining for making cross-sectional shapes in two directions of X and Y into wave shapes is easy and that the flexural rigidity difference between two direction of X and Y is extremely small.

    摘要： [Problem] To provide a molding device and a method for molding a thin plate-shaped substrate, with which it is possible to mold a thin plate-shaped substrate without residual distortion. [Solution] A lower die 10 (first die) and an upper die 20 (second die) are disposed so as to be capable of moving towards and away from each other. Protruding portions 20a are disposed on the upper die so as to protrude towards the lower die, and are provided with leading edges for forming stretched portions 200a stretched by localized pressing of a pre-molded article 200, and side edges for inducing deflection of sections that are continuous with the stretched portions, and forming bent portions 200b in spaces 10s formed in relation to the lower die. Tensioning portions 30 tension and stretch the bent portions. A controller 40 controls the operation of the lower die or the upper die, and the tensioning portions. The bent portions are tensioned and stretched by the tensioning portions while the stretched portions of the pre-molded article are still pressed by the lower die and the protruding portions of the upper die, imparting the shape of the protruding portions to the pre-molded article along the side edges of the protruding portions. The prescribed irregular shape of the pre-molded article is an irregular shape such that bent portions will be formed.
