ABSTRACT:
A press drive mechanism is disclosed which is comprised of a drive shaft having a first eccentric which receives a power link member. The power link member has an end connected to the press slide by means of a connecting link, and the power link member also includes a second eccentric having an axis parallel to and offset from both the drive shaft and first eccentric axes. A rocker link member is received on the second eccentric and has an end pivotally connected to the press frame. The rocker link constrains oscillating movement of the power link member in response to rotation of the drive shaft, thus to control the displacement and velocity characteristics of the reciprocating movement imparted to the press slide.
