FIELD: mechanics.;SUBSTANCE: invention relates to machine building and may be used in the press mechanisms intended for converting a rotational motion into translational one. The press crank mechanism incorporates a crank made triangular and three sliders. Two sliders are linked to the crank via a connecting rod, each of the said slider forming with the guides two cylindrical kinematic pairs. The third slider it liked to one the above two sliders by means of an additional connecting rod, both being arranged in symmetry with the said cylindrical kinematic pairs axes.;EFFECT: maximum effect on the object processed.;2 dwg
