Abstract

PURPOSE: To manufacture a lightweight, highly accurate spool for thin wire at low cost by drawing a plate of Al etc, successively, and staking after piercing a round rod for positioning.
CONSTITUTION: A staked part 3 is formed by bending beneath the lower bulged part of a body made by drawing a disk made of Al etc. A bulging die (a) is held to the upper inside of the body, and the rising part 4 is drawn from outer circumference using sectional dies to form a bulged part 5 and shell part 6. The bulged part 5 is squeezed from above together with the bulging die (a). Then, the bulging die (a) is removed and the bulged part 5 is squeezed completely to form an upper face plate 7 and a collar 8. A center hole 9 is bored at the center of the upper face plate 7 and a reinforcing plate 11 provided with a center hole 10 is fitted into the staked part 3. The reinforcing plate 11 is fixed by staking the staked part 3 with a round rod (c) passed through the holes 9, 10. Then, intersecting point of the collar 8 and shell 6 is shaved to a right angle, and circumferences of the upper face plate 7 and lower face plate are polished.
