Abstract
The present invention relates to methods of working sheet metal, and sheet metal working apparatus for performing such methods. Such methods include steps of 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 defined between the edge and a basal region, the first sidewall portion thereby defining a curved fold region in the sheet metal workpiece adjacent the first sidewall portion. Following this, 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 the anvil tool are then progressively slid along the curved fold region to cause shear material transfer in the curved fold region to further deform the curved fold region. Such 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.
