A long formed article made of one steel sheet includes a top sheet portion extending in a longitudinal direction, a standing wall portion extending downward from each of both edges of the top sheet portion in a width direction, and a protrusion portion formed in a portion of the top sheet portion in the longitudinal direction by overlapping a portion extending toward an outside from each of both ends of the top sheet portion in the width direction and a portion extending toward the outside from an upper end of the standing wall portion, in a non-protrusion region, a recessed part extending in the longitudinal direction is formed in the top sheet portion, and a total value α of inner surface peripheral lengths of the top sheet portion and the standing wall portion in a cross section of the formed article perpendicular to the longitudinal direction in a protrusion region and a total value β of inner surface peripheral lengths of the top sheet portion, the standing wall portion, and the recessed part in the cross section of the formed article perpendicular to the longitudinal direction in the non-protrusion region satisfy 1.01≤β/α≤1.50.

In this press forming method, a formed product which has a hat-shaped cross section, and which is provided with a top surface portion, an outward corner portion, a vertical wall portion, an inward corner portion, and a flange portion, is formed. In a draw forming step, an intermediate formed product 8 including a protruding portion 81 and a recessed portion 83 is formed. The curvature of the protruding portion 81 and the recessed portion 83 are greater than those of the outward corner portion and the inward corner portion, and the cross-sectional shape of the protruding portion 81 is caused to bulge further toward the top surface portion side in a pressing direction F than the outward corner portion. In a restrike forming step, the outward corner portion and the inward corner portion are formed by pushing the protruding portion 81 down in the pressing direction F.

A soldering nozzle (100) for selectively soldering assemblies by means of molten solder supplied through a soldering nozzle (100) from a solder bath. The soldering nozzle (100) is designed as a deep-drawn part. A method for the production of a soldering nozzle (100) is specified as well, including the provision of a blank (401); the drawing of the blank (401) through at least one female die (411, 421) by means of at least one male die (413, 422, 431) to produce an oblong shape (439) of locally annular or substantially annular cross-section, with a first end (436) corresponding to an action point of the male die (413, 422, 431) and a second end (437) corresponding to an introduction cross-section of the male die (413, 422, 431), the cross-section preferably increasing from the first end (436) towards the second end (437); and the formation of an opening (446) at the tip end (436).

A manufacturing device manufactures a component having a hat-shaped section as a pad and a punch sandwiching a center portion of a metal plate, and a die and a holder sandwiching both side portions of the metal plate are moved relative to each other in the upper-lower direction. The manufacturing device includes the die, the pad provided inside an opening of the die so that the pad is able to move relative to the die, the punch arranged to face the pad in the upper-lower direction, the holder arranged around the punch so as to face the die in the upper-lower direction and be able to move downwardly, and a locking block provided on the holder. The locking block is moved from a non-facing position to a facing position and inserted between the pad and the holder after mold closing and before mold opening.

To reduce warping of vertical wall portions without causing buckling during pressing. Press-forming into a hat cross-sectional shape having one linear vertical wall portion and the other curved vertical wall portion and not having a flange portion is performed. A punch and a pad sandwiching a top sheet portion therebetween, bending blades for bend-forming the vertical wall portions, and stoppers facing the bending blades are provided. The punch is supported by a first cushion component. The bending blades each have an upper die component and a lower die component disposed facing each other in the press direction with an interval (D) equal to a set compression amount in the range of 2% or more and 6% or less of the heights of the vertical wall portions and a second cushion component interposed between the upper die component and the lower die component, maintaining the interval (D), and contractible in the press direction. The cushion pressure of the second cushion component is lower than the cushion pressure of the first cushion component and has such cushion pressure that the second cushion component does not contract during the bend-forming of the vertical wall portions.

A press-formed product is manufactured by press-forming a blank material into an intermediate shape, and further press-forming the blank material from the intermediate shape into the press-formed product having a target shape. A product portion of the target shape includes a first ridge line portion and a second ridge line portion each having a radius of curvature of 20 mm or smaller and a bending angle of 130 degrees or larger. The product portion of the intermediate shape has a curved shape having a radius of curvature of 100 mm or larger or a linear shape in a specific cross section. A height of an excess thickness portion of the intermediate shape is higher than 10 mm with respect to a peripheral portion and lower than a height of the excess thickness portion of the target shape.

An apparatus of holding a blank for incremental forming, includes a blank holder to which a blank is configured to be coupled; a motor configured to provide driving power; an interlocking means engaged to the motor and configured to rectilinearly move the blank holder in a direction perpendicular to a forming surface of the blank in conjunction with an operation of the motor; and a controller configured to control the operation of the motor so that the blank rectilinearly moves in accordance with a position of a forming robot configured for forming the blank.

A domer station having a domer assembly, a housing assembly, and a stacked piston assembly is provided. The domer assembly is movably disposed within a domer body passage located in the housing assembly and structured to move between a forward, first position and a retracted, second position. The stacked piston assembly includes a plurality of pistons, preferably three pistons, disposed in series and a pressure supply. The pistons are disposed behind the domer in pressure chambers. The pistons have a constant pressure applied thereto and are biased towards the domer. The pistons are, however, each restrained by a stop and do not contact, or operatively engage, the domer when the domer is in the domer first position.
