摘要： The present invention aims with respect to a negative-angle forming die with a lower die half supporting a rotary cam and an upper die half having an intrusion forming portion cooperating with an intrusion forming portion of the rotary cam upon a descend of the upper die half to form a sheet metal product to avoid the problem that the work (W) is damaged by interference of the rotary cam (5) with portions of the work (W) protruding in a direction extending across the rotation axis during retraction of the rotary cam (5) after the intrusion forming. The rotary cam (5) is divided into at least an end rotary cam section (5 1 ) and a main rotary cam section (5 2 ), both of the divided rotary cam sections (5 1 , 5 2 ) being disposed on the same pivoting axis (L), and the end rotary cam section (5 1 ) being provided with means for restricting the end rotary cam section (5 1 ) from pivoting for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation, and for axially moving the end rotary cam section (5 1 ) relative to the main rotary cam section (5 2 ) for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation.
