Orientation of parts on stencil oscillating in horizontal plane

Abstract

Orientation of parts when a stencil is oscillating in horizontal plane and these parts are impacted by stimulating forces is analyzed. The phases of parts movement towards the stencil holes and their falling into the holes was researched. The dependencies of an average velocity of movement under the impact of stimulating force, amplitude of stencil oscillations, excitation frequency and the factor of friction were determined. The expression to calculate allowable frequency of stencil oscillations was obtained. The dependencies of allowable frequency of oscillations upon oscillations amplitude and velocity of the part falling into holes were formed.
