抄録

For CO₂ emission reduction, an incremental flattening process in which sheet metal waste is recycled with non-heating has been proposed. In this process, a bent sheet is unbent into a sheet metal with a triangular residual corner, and this residual corner is flattened incrementally. During the incremental flattening, the thinned bent corner can be thickened. However, this incremental flattening process has a problem in which the thickness of the bent corner after flattening is thinner than the thickness of the surroundings. To overcome this problem, we investigated the thickening behavior of the bent corner during the incremental flattening and experimentally clarified the possibility of the increase in the thickening of the bent corner from considering of this thickening behavior. It was found that the bent corner buckled during incremental flattening. Experimental results showed that this buckling of the bent corner was controlled by shortening the length of the triangular side of the residual corner, and the thickening of the bent corner increased. Furthermore, work-hardening exponent of sheet metal influenced on the thickening of the bent corner.
