MECHANICAL PRESS

摘要

A guiding arrangement for the reciprocating slide 56 of a mechanical press includes guideposts 58 which are rigidly connected to the crown 20 of the press and depend downwardly therefrom, passing through guide bushings 66 in the slide assembly. The crown 20 is connected to the bed of the press by uprights 18. In order to counteract the non-vertical forces exerted on the slide by connection arms extending from a crankshaft in the crown and pivotally connected to pistons connected to the slide and moving in cylinders fixed to the crown, which forces tend to cause the slide to tilt about a horizontal axis perpendicular to the axis of the crankshaft, hydrostatic bearings are mounted between each piston and cylinder to exert restraining forces in a direction perpendicular to the axis of reciprocation of the slide and along lines which intersect the axis of rotation of the pivotal connections to the pistons.
