Abstract
PURPOSE: To carry out the curling work small press load, by vertically actuating the preliminary curling tool edge and also the main curling tool edge, when the upright circumferential flange of the metallic panel is curled into other metallic panel.
CONSTITUTION: The metallic sheets 18, 20, as the work are placed on the lower die 16, and the piston 32 is ettended to the left by the action of the hydraulic cylinder 24. The levers 28, 31, are placed approximately on one line by the torque device 22 at the tip of the piston 32. Hereupon, the tool edge 52 bends the flange 18' of the work 18 by 45 degrees, and the preliminary curling is finished. The compressed air is introduced into the bag 68 between upper die 44 and the upper surface plate 14, and is expanded so as to bring down the upper die 44. Hereupon, the lever 56 holding the tool edge 52 rotates around the pin 54 cooperating with the link 58, and the tool edge 52 retires without interfering with the descending tool edge 66 attached to the upper die 44. Then, when the bag 68 further expands and becomes nearly true circle, the back face of the tool edge 66 acts on the flange 18' bent by 45 degrees, so as to perfectly bend it, and the main curling work is completed.
