Claims

[Claims for Utility Model Registration] (1) Providing a protruding part and a flat part that bisect the end face of the punch that corresponds to the die, and providing a protruding part and a flat part that bisect the end face of the die that corresponds to the punch, A step-bending mold for a plate material, characterized in that opposing surfaces of the protruding parts of the punch and die are provided in parallel with a distance of approximately the thickness of the workpiece. (2) The protruding part of the punch and the facing surface of the die are set so that the vicinity of the center of one of them is in contact with the upper surface of the flat part of the other party via the plate material, so that the amount of protrusion on both sides is reduced as they move away from each other. A step-bending mold for plate material according to claim 1, characterized in that a tapered portion having a slope is provided. (3) For punches that step-bend curved parts, the width of the height part that contacts the top surface of the flat part on the die side through the plate material is narrowed, and the amount of protrusion on both sides that are moving away from each other is reduced, so that the bottom surface of the flat part of the punch The part that is the same height is approximately 60
A step-bending mold for a plate material according to claims 1 and 2 of the utility model registration claim, characterized in that the mold is provided at a central angle of 100 degrees.
