Abstract
In a machine press with at least three slides, the phases for the stroke of a leftmost slide and a rightmost slide are made identical. The strokes for other slides interposed between the leftmost and rightmost slides are out of phase with the leftmost and rightmost slides. The lower dead point of each slide is the point of maximum pressure. Since the difference in phase of the strokes of the slides causes the lower deadpoints of the leftmost and rightmost slides to occur either before or after the lower deadpoints of the other slides, the total instantaneous eccentric load on the multiple slide machine press is reduced.
