Abstract

PURPOSE: To form grooves in one process with good accuracy by performing grooving of the end part with a restriking punch at the same time of bending and forming build-up toward the inner side.
CONSTITUTION: The work is placed on a cushion pad 3 and is clamped to the divided punch blocks 7, 7 supported by means of pins 10 on both sides of a center punch 6 so as not to deviate with the pad 3. Next, the work is bent by the punch blocks 7, 7 and the flange 17 of the work is put in a die 1. When the work is pressed further, the punch blocks 7, 7 slide laterally along the slope a of the center punch 6 and further when a punch plate 12 is lowered, the end of the restriking punch 11 mounted to a cylinder 4 abuts against the top end of the flange of the work thereby forming the required groove and at the same time forming the build- up part protruding to the inner side.
