Deep-drawn part manufacturing method for e.g. vehicle construction, involves performing reverse bending movement for reverse bending section of edge region of plate shaped, deformable workpiece in direction

摘要

The method involves performing a deep-drawn movement in a direction for deep-drawing an edge region (6) of a plate shaped, deformable workpiece (5). The workpiece is held in a flange region and a material of the workpiece is flown out from the flange region into the edge region during the deep-drawn movement. A reverse bending movement is performed for reverse bending a section of the edge region in another direction. Reverse flow of the material of the workpiece from the edge region into the flange region is prevented during the reverse bending movement. Independent claims are also included for the following: (1) a method for controlling a deep-drawn part (2) a deep-drawn part comprising a deep-drawn die.
