Abstract
A hemming die tool assembly for use with an anvil supporting a workpiece to be hemmed. A mounting plate is pivotally secured about an axis relative to the anvil while a vertical slide is slidably attached to the mounting plate along a first direction. An elongated channel is attached to the vertical slide so that the axis of the channel is transverse to the first direction. A hemming tool is secured to the vertical slide while a rocker arm is pivotally secured at one end to the mounting plate about the pivotal axis of the mounting plate while a second end of the rocker arm is longitudinally slidably mounted in the channel. A first cam assembly pivots the mounting plate between a retracted position, in which the hemming tool is positioned away from the workpiece, and an extended position in which the hemming tool overlies the workpiece. A second cam assembly pivots the rocker arm about its pivotal axis and, in doing so, vertically displaces the vertical slide relative to the mounting plate to perform the prehemming operation.
