Abstract:
A slider link press device having a front face and an opposing rear face, the device comprising:a crank shaft lying along a longitudinal axis extending in the direction from said front face to said rear face resulting in the crank shaft being orientated in a front-rear direction; a fulcrum shaft lying along a longitudinal axis extending in the direction from said front face to said rear face; first means for linking said crank shaft to said fulcrum shaft; said first means having a body that is pivotably retained on one side by said fulcrum shaft and being operable in a first arc about said fulcrum shaft, said body lying along an axis that is at least substantially parallel to said front and rear faces; said body of said first means being perpendicular to said crank shaft and said fulcrum shaft; a crank pin on said crank shaft; said crank pin providing an eccentric displacement to said first means; a slide having a top and a bottom dead center position; second means for linking said first means to said slide; said first means increasing a force applied to said slide at said bottom dead center and increasing a slide descent time whereby a precision increases and decreases a slide assent time; guide means for guiding said slide in said cycle; said guide means eliminating eccentric loads upon said slide during said cycle, whereby said precision increases; and a drive means for driving said press device and apply said force to said slide.
