A plate member (10) is mounted on a supporting frame (11). The periphery of the plate member (10) is firmly secured by a clamp (12) and a concave die-shaped lower pushing member (13) is caused to rise from below. The lower pushing member (13) is provided with a forming concave area (15) and a forming convex area (16). Disposed above the plate member (10) is a bar-shaped upper pushing member (20) which is lowered to push against the plate member (10). In such a condition, the plate member (10) is caused to rise together with the lower pushing member (13) and move in the directions of X and Y to form convex areas (17) and (18) within the forming concave area (15) and the forming convex area (16). The upper pushing member (20) is provided with a main body (21) of high rigidity and a flexible member (22). The flexible member (22) is formed in a hemispherical shape and made of material more elastic than the main body (21) which is made of hard polyurethane or the like, thereby making spherical contact with the plate member (10).
A sequential forming device comprising a plate member, a bar-shaped pushing member adapted to push the plate member from one side, and a die-shaped pushing member adapted to push the plate member from the other side, the plate member being inserted between the bar-shaped pushing member and the die-shaped pushing member, wherein a contacting section between the plate member and the bar-shaped pushing member is caused to move three-dimensionally to have the plate member formed into a predetermined three-dimensional shape, a section of the bar-shaped pushing member contacting the plate member is a flexible member and the die-shaped pushing member includes at least one concave area of a substantially oval shape and at least one convex area having stepped peripheral sections, the at least one concave area having a deep area and a shallow area.
