Abstract

PURPOSE:To easily form a plate stock bending part whose ridge line is clear and excellent in its design by forming a step difference in the bending direction at the bending position of a plate and after press-forming a recessed part at the bending inner side part executing bending with the step difference outer side as the reference. CONSTITUTION:A plate 1 is mounted on a holding plate 3 energized by a spring 4 located at both sides of a die 2 with a triangular projecting part 13 at the tip and a pressurizor 7 with a pressurizor 8 is descended by a spring 9 energization to press-forming a recessed part C at inner side of a step difference part D at the bending position of the plate 1. This formed body 15 is mounted on a die 20 and subjected to bending by a punch 25 with pressing the body 15 by a stripper 26 with the energizing of a spring 21. The worked plate bending stock has small face part R and whose ridge line is clear and excellent in its design, so the less man-hour will do as well.
