A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material, and a press working step of performing press working on the starting material by using a punch, and a pad and a die that are paired with the punch. The press working step includes a first step of forming, by the punch and the pad, the entire region of a top panel part, the entire region of each of a ridge line parts including the shape-changing part, and a region up to a predetermined height from the border between a vertical wall part and the ridge line part of a region of each of the vertical wall parts, and a second step of forming, subsequent to the first step, by the punch and the die, the remaining regions with the starting material sandwiched between the punch and the pad.

The invention relates to a method for producing a cylindrical component, particularly of turbomachines. In the process, a heated blank is provided. The blank is then formed to create a flat blank (2). The flat blank (2) is next bent and/or rolled to form a cylindrical half-shell (40).

Certain embodiments of the present invention relate to arcuate saddles typically used to anchor and suspend insulated or non-insulated pipes. One or more adhesive strips are mounted to the interior, concave surface of the saddles. In preferred embodiments the adhesive strips extend transverse to or parallel to the longitudinal axis of the saddles. Certain embodiments of the present invention involve methods of manufacturing arcuate saddles with adhesive strips.

A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material; and a press working step of performing press working on the starting material. The press working step includes: during a time period from when pushing-in of the starting material into the die by the punch is started or immediately thereafter until the pushing-in of the punch with respect to the die reaches a predetermined distance short of a bottom dead point for the pushing-in, holding the pad at a position distant from the punch by the predetermined distance; when the pushing-in of the punch with respect to the die reaches the predetermined distance short of the bottom dead point, receiving the pad in the die; and continuing the pushing-in of the punch with respect to the die and the pad to the bottom dead point.

A method for producing a metal sheet with raised lines uses a rolling mill including a roll stand and produces a metal sheet including, on each of an upper surface and a lower surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, an incorporating step, and a forming step. In the preparing step, grooved rolls are prepared, each of the grooved rolls including a plurality of grooves in an outer peripheral surface. In the incorporating step, the grooved rolls are incorporated in the roll stand as an upper roll and a lower roll, respectively. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved rolls.

A method of production of a shaped article able to suppress occurrence of shaping defects, that is, a method of production of a shaped article including a first step of press-forming a metal plate (1a) into a U-shape to obtain a U-shaped article (1b) having a bottom part (2) straight extending in a longitudinal direction and a second step of press-forming the U-shaped article (1b) to bend it in the longitudinal direction so that the bottom part (2) of the part projects to the inside and obtain a U-cross-section bent article (1c).
