A process includes producing a group of automotive components by forming components having various global geometries via a common tooling configured to bend a blank sheet of metal to create a variable cross section profile, forming an addendum as an integral portion of each formed component, and altering the global geometries in a series of incremental deformations to create local geometries while each component is affixed to a deforming machine via the addendum.

There is provided a method of manufacturing a curved channel part having a curved portion in a vertical wall portion by press forming, the method restricting stretch flange deformation, which occurs in the vertical wall portion and a flange portion. The method includes a shear deformation step as a step of forming the vertical wall portion. In the shear deformation step, a boundary-side portion of a base section of a blank with respect to a deformation section, and an outer portion of the deformation section are individually restrained, a portion to be a vertical wall portion of the deformation section is shear-deformed in a sheet face, and a material is caused to flow from a portion separated from a curved portion toward the curved portion in an outer edge portion of the portion to be the vertical wall portion.

A frame system for a building structure includes beam members. Each beam member comprises two opposed, parallel flanges. A web is interposed between the flanges. Spreader members comprise two opposed, parallel side flanges, a web interposed between the side flanges and two opposed end flanges bridging the side flanges at respective terminal ends of the web. The beam members and the spreader members are configured to be fastened to each other to form a frame assembly.

Forming roll units included in an apparatus for manufacturing a roll-formed component each include a roll pair. The roll pair includes a receiving roll part and a first bending roll part that face each other. A plate member passing area is formed below the first bending roll part, the plate member passing area allowing a roll formed member excluding its side edge portions to pass through. The roll pair is configured to make, during bending, sliding movement in a width direction of the roll formed member and rotational movement about a normal direction to the roll formed member as a rotational center.

The present invention relates to methods of working sheet metal and an apparatus. Methods include providing a sheet metal workpiece having first and second surfaces opposed to each other and at least one edge, bending the workpiece to form at least a first sidewall portion, the first sidewall portion thereby defining a curved fold region in the sheet metal workpiece adjacent the first sidewall portion. The first anvil tool and a first forming tool are provided for contact with and constraint of the first and second surfaces of the sheet metal workpiece respectively. The forming tool and/or anvil tool are then slid along the curved fold region to cause shear material transfer in the curved fold region to further deform the curved fold region. Methods can allow for formation of components of similar shape as made at present by deep drawing methods, but with less wastage of the starting material.
