Abstract
A stamped workpiece for use as a motor-vehicle part is made by first forming from sheet metal an intermediate workpiece extending along an axis and forming in axially opposite ends of the workpiece respective outwardly directed V-shaped formations. The workpiece is then set directly or indirectly via blank holders on one die of a stamping apparatus and one of the formations is engaged with a complementarily shaped element of the one die. Then another element complementary to the other of the formations is engaged against the other formation and the workpiece is axially gripped between the elements. Finally, another die of the apparatus is pressed against the workpiece on the one die to stamp the workpiece into a finished shape.
