Abstract
A work feed method and apparatus for feeding workpieces to and from the die of a press comprises a feed rack having a workpiece clamping device thereon is disposed within the press gap and reciprocates horizontally between positions where it picks up pieces from a supply stage at the die and transfers them simultaneously to the die and discharge stages. The feed bar is operated by a drive unit driven by an electric motor and having a rocking arm mechanism connected to the feed bar to reciprocate the latter horizontally and a slide mechanism at each end of the feed bar to reciprocate the feed bar vertically which is operated by a camming mechanism through a ball crank device which is operated by a lift rod driven through a camming mechanism by the drive motor.
