Abstract
PURPOSE: To easily bend the edge of a metallic plate without warping a bent part in case when said edge part is turned up flatly by bending, by supporting the metallic plate on a presser and bending it at the edge with a sliding cam and a punch.
CONSTITUTION: After parting a die holder 11 from a punch holder 12 in the press, the metallic plate A to be worked is mounted on a sliding cam 19 from a presser 14 of the die holder 11. While pressing the end of the metallic plate A to a positioning member 23 provided on the sliding cam, the punch holder 14 is lowered and the metallic plate A is pressed by a punch 29. The punch holder 12 is lowred further, and with the lowering of the presser 14 the metallic plate A is bent upward at a right angle at the part which is supported by the sliding cam 19. Then, the tapered surface 35 of a driving cam 30 pushes the sliding cam 19. And the sliding cam 19 is pushed to the right, compressing a spring 21 and pushes up the edge part of the metallic plate which is bent at a right angle by a projecting part 25. After releasing from the punch 29 the edge of the metal is pressed by the lowering punch 29 forming a flat folding.
