Abstract
PURPOSE:To mass-produce highly accurate toothed pulleys having continuous teeth on inner and outer circumference in manufacturing toothed drums from plates by applying press formation plate work and rolling work. CONSTITUTION:A circular plate is punched from a band plate and plate worked to a cylindrical body 2 by a transfer press machine. An inner die roll 5 is closely fitted in the cylindrical body 2 allowing coaxial rotation, and tooth form 5a formed on its circumference is brought into contact with a roll 6 that has tooth form corresponding to the inner die roll 5 on the outer face of circumferential wall 2b. The circumferential wall 2b of the cylindrical body 2 is interposed between the inner and outer die rolls 5, 6. Further, a backup roll 7 is brought into contact with the circumferential wall 2b of the cylindrical body at the outer face of the body 2 that is opposite to the roll 6. Rolls 6, 7 are rotated at equal speed to permit the tooth form 5a, 6a of the two rolls to bite the circumferential wall 2b of the cylindrical body to cause plastic deformation. A toothed drum is manufactured by forming continuous teeth 3a on inner and outer circumference of the cylindrical body 2.
