Abstract
The present invention has its object to provide an efficient, general use shaping technique for forming high strength sheet metal into a three-dimensionally complicated shape. Further, the present invention provides a working apparatus for shaping sheet metal comprising a die (also called a 'punch') which has a shape suitable for a shape of shaped sheet metal, a plurality of rolls which grip sheet metal (H) with the die to shape the sheet metal, roll movement mechanisms which makes the rolls independently move in a horizontal direction and make them independently ascend or descend in a vertical direction, and a roll angle setting mechanism which can change an angle by which the rolls are pressed against the die.
