Abstract
PURPOSE: To manufacture a metallic article provided with the symmetrically V- shaped top and bottom ends in accuracy at low cost, by first forming both of top and bottom ends of a metallic strip into a deformed V-shape, and by bending back the shoulder part of this deformed V-shape.
CONSTITUTION: A metallic strip 2 is put on a V-block 4 provided with two V- grooves 4a and two gradients 4b; a V-punch 5, provided with two V-projections 5a and two gradients 5b, is pressed down onto the V-block 4; hereby, a metallic article 6, provided with top and bottom ends formed into a deformed V-shape, is prepared. Two lifting dies 8, respectively possessing a gradient plane 8a for touching and backing up the shoulder part 6a of the metallic article 6, are put on upper surface of the die holder 7 on its left and right ends; and a stripper plate 10, fittable to the flat part 6b of the metallic article 6, is tight set to the holder 7 using a bolt 9 interposing a spring 11. The metallic article 6 is put on the plate 10, and the pressure plate 12 is put on the metallic article 6; then, the pressure plate 12 is pressed down. The back 6a of the V-shaped metallic article 6 is raised while being backed up by the die 8, and the shoulder part 3 is bent back to the initial flat plane; hereby, a product 1 provided with V-shaped top and bottom ends is finished.
