Abstract
A knockout mechanism for a high-speed automatic cold heading machine having first and second eccentric shafts. A driving link is mounted on the first eccentric shaft by an antifriction bearing. A rocker arm is pivotally connected to the driving link at a location spaced from the connection of the link to the first shaft. The rocker arm is connected to the second shaft so that the rocker arm continuously oscillates. Knockout means including an ejecting rod are actuated by the rocker arm to eject a blank from a die of the machine. The stroke of the rocker arm is adjusted by adjusting the second eccentric shaft.
