特徴とするフランジ加工用プレス型。 A press die that bends and forms a flange portion at the end of a panel-shaped workpiece by relative movement between a punch and a flange die having a forming surface parallel to the forming surface of the punch, the flange die having a forming surface parallel to the forming surface of the punch. A plurality of flange forming surfaces having steps in the direction of engagement clearance between the punch and the flange die are formed continuously in the direction of relative movement, and the engagement length of the flange die with respect to the punch is selectively determined according to the flange forming surface. A press mold for flange processing characterized by being equipped with a switching means for switching.
