The present invention relates to a method for producing a dimensionally stable sheet metal component, wherein the method includes preforming a metal sheet into a sheet metal preform comprising at least one base region, a frame region, a transitional region between the base region and the frame region, optionally a flange region and a transitional region between the frame region and the flange region, wherein at least one of the regions comprises excess material at least in portions. The sheet metal preform is cut at least in portions to form a cut sheet metal preform with a sheet metal preform The sheet metal preform is one of swagged and calibrated which has been cut at least in portions to form a substantially finished formed sheet metal component.

Provided is a manufacturing method for a rectangular can according to which it is possible to bring an angle formed by a step surface of a step provided in a rectangular can body and an inner wall surface of the rectangular can body closer to 90 degrees. In a step-forming step, using a die 310 that is provided on an outer wall surface side of a sidewall on which the step is to be formed, a mandrel 410 for sandwiching the sidewall between the mandrel 410 and the die 310 on the bottom side relative to a portion where the step is to be formed in the inner wall surface on which the step is to be formed, and a punch 420 for pressing the side opposite to the bottom side relative to the portion where the step is to be formed in the inner wall surface on which the step is to be formed and compressing the sidewall between the punch 420 and the die 310, the step is formed by performing multiple instances of a pressing operation performed by the punch 420.

A modular tooling die for an axle housing includes a plurality of separable and coaxially aligned die sets. Each die set may include a cam driver that is engageable with first and second cam slide assemblies. The cam slide assemblies move toward one another along an axis that extends perpendicularly to an axis along which the cam driver translates. Multiple die sets are provided for possible use in a single press depending on the particular axle housing geometry to be manufactured. A wide variety of different geometrical configurations may be formed by simply replacing one or more die sets and inserting a differently sized or shaped blank within the press. A method of manufacturing various axle housings and the associated modular tooling is described.

This press-formed article includes: a top sheet portion; a sidewall continuing to the top sheet portion via a convex ridge line portion; a flange continuing to the sidewall via a concaved ridge line portion; and an outward flange continuing from an edge portion of the top sheet portion to an edge portion of the flange, via an edge portion of the convex ridge line portion, an edge portion of the sidewall, and an edge portion of the concaved ridge line portion, wherein in the same unit, an average thickness T.sub.Ave, a minimum thickness T.sub.Min, and a maximum thickness T.sub.Max of the outward flange satisfy Equation 1 and Equation 2.

Device to produce a stamped part includes a punch having a bearing surface, an anvil, a die and a magnetic field generator, provided in the punch, level with the bearing surface. The device is configured, in an initial position, so that: the bearing surface of the punch receives a portion of a first face of the blank, the anvil and the magnetic field generator are placed on either side of the same portion of the blank. The magnetic field generator being opposite a first face and the anvil opposite a second face of the blank, at a distance from the second face. The die is placed opposite the second face, level with another portion of the blank. The magnetic field generator applies pressure on the blank in a direction Z′Z of the anvil. The device includes two actuators to move the punch and the anvil, respectively, in the direction Z′Z.
