  • Automatically adjustable multiple CAM for forging machine
    Patent number: 5732589
    Abstract: A progressive forging machine having automatically adjustable cam timing for transfer finger opening and closing movement and for knockout pin action. The cams can be adjusted without manual effort to thereby reduce changeover time and the level of skill required to effect a changeover. For each of the transfer finger and knockout actions, a separate cam assembly is provided with a series of cam sections that are selectively repositionable on a common shaft by appropriate operation of a corresponding series of cam stop actuators and a common clutch actuator.
