ABSTRACT:
Apparatus is provided for forming sheet metal utilizing two opposed sets of rams placed in matrix arrays with corresponding rams of opposite sets in alignment. The rams are individually movable and are positioned so that their extremities define a surface having the desired configuration. The two sets of rams are then used to form a workpiece in the same manner as dies. Pivotally mounted work-engaging heads with rounded surfaces are provided on the rams to improve the surface finish of the workpiece.
