An object of the present invention is to provide a method for manufacturing a molded member, which can maintain high accuracy circularity of an inner diameter of a tubular body even if a thickness of a base metal sheet varies and which can prevent occurrence of adhesion, seizure of the like of the base metal sheet to a die used for finishing ironing. The base metal sheet is subjected to multi-stage drawing to manufacture the molded member including a tubular body and a flange formed at an end portion of the body. The multi-stage drawing includes: preliminary drawing for forming a preliminary body having a body element from the base metal sheet; at least one compression drawing performed after the preliminary drawing and forming the body by drawing the body element while applying a compressive force to the body element; and at least one finishing ironing performed after the at least one compression drawing to ensure dimensional accuracy.

A method of manufacturing an arc corner connecting rib of a metal box shell is disclosed. The method of manufacturing comprises the following steps: preparing a rectangular metal shell whose vertex corner portions are arc corner transition portions; drawing for a first time by means of a first metal drawing mold a top face plate of the rectangular metal shell, so that a plurality of first convex strips are formed in a first area between the two arc corner transition portions of the top face plate; and drawing for a second time by means of a second metal drawing mold a side face plate and the arc corner transition portions of the rectangular metal shell obtained after the first drawing molding, so that a plurality of second convex strips are formed in a second area between the two arc corner transition portions of the side face plate.

A hot-pressed member includes a steel sheet, a Ni-diffusion region present in a surface layer of the steel sheet, and an intermetallic compound layer and a ZnO layer which are provided in order on the Ni-diffusion region, the intermetallic compound layer corresponding to a phase present in a phase equilibrium diagram of a ZnNi alloy, wherein a spontaneous immersion potential indicated in a 0.5 M NaCl aqueous air-saturated solution at 25 C.5 C. is 600 to 360 mV based on a standard hydrogen electrode.

A deep-drawing machine having a forming station configured for forming containers into a first sheet-shaped material, and a cutting station disposed downstream of the forming station in a working direction. The cutting station is configured to cut or to perforate an area of the sheet-shaped materials disposed between the containers. The cutting station may include a rotation cutting device that comprises a cutting cylinder and an opposing cylinder. A method for operating a deep-drawing machine that comprises the following steps: forming containers into a first sheet-shaped material by a forming station, and cutting or perforating of the sheet-shaped materials in an area between the containers after forming of the containers using the rotation cutting device.

A method for manufacturing a pressed component including forming a metal sheet into a pressed component shape having: a cross section having a top sheet portion and a side wall portion continuous to at least one side in the width direction of the top sheet portion via a first bent portion; and having one or two or more curved portions in which the top sheet portion is curved to project or to be recessed in a side view along the longitudinal direction in the direction intersecting the cross section, the method which includes: a first preliminary forming step having a step of forming, to the metal sheet, first beads extending along the longitudinal direction at a position where the first bent portion is formed; and a first component forming step of forming the metal sheet after the first preliminary forming step into the pressed component shape.

A tool arrangement is disclosed for integration in a production line for producing a hot formed component from a blank which is produced from a hot forming steel strip. The tool arrangement includes a housing, which delimits an interior of the tool arrangement relative to a surroundings of the tool arrangement, a tempering station for tempering the blank and a hot forming station for hot forming the blank. The tempering station and the hot forming station are jointly arranged in the interior.

A sheet metal strip is directed from a supply coil into a unitized system including a frame supporting a feed roll driven by a variable speed motor. The strip is directed upwardly from the feed roll between vertical guide rods to produce an inverted U-shaped vertical loop detected by sensors connected to control the feed roll motor. A servo driven index roll receives and advances the strip into tooling within a reciprocating press. Vibration insulators support the frame from a base stand mounted on air casters which provide for quickly removing the system from the press. The axial length of each roll is less than the width of the strip and engages only a center portion of the strip. A second index roll driven by a servo motor may be used on the press to provide push/pull advancement of the strip through the press.

A method for producing a hot-pressed member includes heating a coated steel sheet, which includes, on a surface thereof, a ZnNi alloy coating layer containing 10% by mass or more and less than 13% by mass of Ni at a coating weight of over 50 g/m.sup.2 per side of the steel sheet, in a temperature region of an Ac.sub.3 transformation point to 1200 C. at an average heating rate of 12 C./second or more, and then hot-pressing the steel sheet.

A method for manufacturing a press-formed product, the method including press forming a first formed product from a blank material, press forming a second formed product from the first formed product, and press forming the press-formed product from the second formed product. The press-formed product is a member extending in its longitudinal direction, and includes a top plate and two vertical walls. The first formed product includes a preliminary top plate, an inclined section, and a flat section. The second formed product includes a preliminary top plate, an inclined section, and a preliminary vertical wall. The preliminary vertical wall is formed by deforming the flat section while the preliminary top plate and the inclined section in the first formed product are held between dies.

A method of manufacturing a storage container for storage in a stack in a grid framework structure comprising a plurality of storage columns, each of the plurality of storage columns being configured to store a stack of storage containers. The method comprises the steps of: forming a lower part of the storage container by the steps of: stamping or drawing a sheet metal blank into a drawing die to form a tray-shaped preform comprising a base with a raised rim and a flange; turning the flange to define a connection surface that extends in the same direction as the raised rim of the tray-shaped preform to form a container having a predefined depth; forming an upper part of the storage container by the step of: stamping sidewalls and/or end walls from one or more separate sheet metal blanks; attaching the lower part to the upper part by attaching the sidewalls and end walls to the connection surface of the container.
