A press-formed article that includes a top sheet portion, a peripheral wall portion formed along three peripheral edge portions of the top sheet portion, a floor flange portion, a side standing flange portion extending outward from a circumferential end portion of the peripheral wall portion, and an inclined flange portion that is an inclined wall continuous between the side standing flange portion and the floor flange portion.

A method includes: forming either one or both of convex and concave bead portions at surface portions corresponding to sites of a side wall portion on both sides of a convex curve site and to sites of a side wall portion on both sides of a concave curve site; and squashing the bead portions, wherein the bead portions formed on both sides of the convex curve site are tilted such that an end part of the bead portion positioned on the convex curve site side is farther from a baseline and the other end part is closer to the baseline; and the bead portions formed on both sides of the concave curve site are tilted such that an end part of the bead portion positioned on the concave curve site side is closer to the baseline and the other end part is farther from the baseline.

Provided is a cam type press capable of controlling deformation of a flange of a panel in the course of processing the flange, thus reducing deformation such as a crease, or the like, of the flange. The cam type press includes a padding cam installed to be movable in a slope direction. A slider is installed to be movable toward the padding cam, with a process gap into which a portion of a panel is inserted to form a flange between one side of the padding cam and one side of the slider. An adjustment block adjusts the process gap provided between the other side of the padding cam and the other side of the slider.

An automatic unloading, clamping and molding device for galvanized iron tubes and a manufacturing method thereof are used to position at least a crude pipe sleeve at a material strip and drive the crude pipe sleeve to pass through a positioning segment, a molding segment, a reshaping segment and unloading segment in a molding device for development of a plurality of graspable claw portions on the sleeve wall of the crude pipe sleeve and mass-production of stable-quality and low-manufacturing-cost pipe sleeves, each of which has a plurality of graspable claw portions.

A production method includes a placement step, a first pressing step, and a second pressing step. In the placement step, a blank plate is placed in press tooling. In the first pressing step, the blank plate is caused to undergo bend forming in such a way that concave ridges, a concave area, and areas of concave-correspondence vertical wall areas that are areas adjacent to the concave ridges are formed in the blank plate. In the second pressing step, the resultant plate is caused to undergo draw forming in such a way that convex ridges, a convex area, areas of convex-correspondence vertical wall areas that are areas adjacent to the convex ridges are formed in the resultant plate.

A method of manufacturing a press-molded article includes: projecting an inner pad, provided at an apex portion of a punch, from the punch toward a side of a die, and disposing a metal sheet blank on the inner pad; and projecting a die pad, provided at the die, from the die toward a side of the punch to dispose the die pad at a position separated from the inner pad by a predetermined distance that is greater than a plate thickness of the metal sheet blank; forming a side walls by moving the die toward the punch side relative to the die pad, the inner pad, and the punch, and integrating the die pad with the die; and forming a top plate by moving the die and the die pad, which have been integrated, and the inner pad, toward the punch side relative to the punch.
