Abstract
PURPOSE: To easily bend the edge of the blank, and to prevent the manufactured taper pipe from deforming into the chestnut type section, by pressing and sliding the blank along the edge of the die holder possessing the same curvature as that of the outer surface of the taper pipe.
CONSTITUTION: The sheet material 2 is placed on the die holder 1, and is fixed by the clamp 4. Then, the edge bending die 5 is fitted to the edge of the sheet material 2, and the edge of the sheet material 2 is clamped between the die holder 1 and the caliber face of the die 5. Next, the motor 11 is driven to rotate the wheel 10 which then winds up the wire 9 and draws the die 5. Hereby, the edge of the sheet material 2 is gradually bent along the curved caliber face of the die 5, and is perfectly pressed against the curved face of the die holder 1 at the exit of the die 5 and is bent into the same curvature as that of the curved face of the die holder 1. Thus, the edge of the sheet material 2 can be easily bent without necessity of the large scale press machine.
