Abstract

PURPOSE: To make possible working the flange part to a small sheet-metal gage by combining roll working using rolls to press U-bending.
CONSTITUTION: An elevating punch 2 is provided betwen a pair of rolls 1, 1', and a cushion pad 3 is disposed below this. The blank sheet metal (a) to be worked is pushed between the rolls 1 and 1' by the punch 2, and is bent to a U shape; at the same time, the flange part is compressed in the thickness direction by the rolls 1, 1', whereby the sheet-metal gage is decreased. In this case, the rolls 1, 1' and the punch 2 are set at t1 smaller than the gage t0 of the blank sheet metal, and the thickness is decreased by the pushing force P of the punch 2. Further, as the blank sheet metal is formed, the rolls 1, 1' revolve; thereore, the flange part is rolled with small deformation resistance.
