ー。 In a punch and a die, each having trim blades that can be moved toward and away from each other and work together to trim a workpiece when they approach each other, the trim blades of the punch and die approach and work together to trim the workpiece. When trimming, the scrap cutter 3 has continuous blades 2 and 9 that perform trim processing simultaneously over the entire trim line, and the scrap cutter 3 has a scrap cutting blade 21 and a scrap cutting blade 21 that are at approximately the same height level as the trim blade 2. The slope portion 21 has a scrap cutting blade constituted by a diagonal cutting blade 21a whose cutting blade is the end of the slope portion 21b provided on the upper part of the scrap cutter 3.
The scrap cutter 3 A cutting blade 25 is formed which can cut the scrap in cooperation with the cutting blades 21 and 21a of the scrap cutter 3, and is adjacent to the cutting blade 25 and cooperates with the slope portion 21b of the scrap cutter 3 to complete the trimming process. At the same time, a cutting and bending blade 22 is formed that can bend the scrap cut off from the product until it reaches the bottom dead center of the press stroke. A trim-type scrap cutter characterized by forming protrusions 23 that cooperate to form the scrap into a downwardly convex shape until the bottom dead center of the press stroke.
