Improvement of the pneumohydraulic amplifier for press machines: Design and parameter calculation

Pneumohydraulic pressure amplifiers are widely used in mechanical engineering. Using a pneumohydraulic amplifier makes it possible to minimize the size of presses while simultaneously multiplying their technological effort. A significant disadvantage classical method force multiplication is low speed movement working bodies equipment under hydraulic drive. The article proposes fundamentally new design amplifier, which high-speed pneumatic cylinder carries out idling tool, and carried only at stage stroke, allows many times increase performance amplifier. This effect achieved by using movable chamber. engineering formulas diagrams presented for calculating parameters allow engineers adapt various conditions. economic when proposed productivity press equipment.
