成されていることを特徴とする曲げ加工用プレス金型。In a press die, the edge of the workpiece is pressed and fixed onto the upper surface of the lower mold by a pad attached to the upper mold, and is bent by an upper curved blade provided on the upper mold and an upper curved blade provided on the lower mold.
The upper curved blade is attached to the upper mold so as to be movable in a lateral direction substantially perpendicular to the moving direction of the upper mold, and has a cam surface inclined downward toward the lower mold side in order to bring the upper curved blade closer to the upper curved blade. an elastic body having a cam disposed below the upper curved blade, an inclined surface corresponding to the cam surface formed at the lower part of the upper curved blade, and moving the upper curved blade in a direction separating the upper curved blade from the lower die; Further, the upper curved blade is formed with a first edge portion for vertically bending the workpiece by lowering the upper curved blade and a second edge portion for horizontally bending the workpiece by lateral movement of the upper curved blade. A press mold for bending processing.
