A simple structure is provided for the frame by changing the orientation of the crank mechanism so as to orient the crankshaft longitudinally. More specifically, the structure includes two ring-shaped main plates are provided in the front and back and are connected by means of connector plates. An upwardly and downwardly movable slide for the machine press is provided in a space demarcated by four column portions of the ring-shaped main plates and a bolster is provided atop a bed of the ring-shaped main plates. A crankshaft oriented longitudinally is provided at the crown portion of the ring-shaped main plates, and the slide is moved upward and downward by a drive mechanism that includes the crankshaft.

Machine press

A slide guide device for a press guides a slide in a cycle. The slide guide device eliminates eccentric force misalignment and prevents eccentric contact between the slide and a gib. The slide includes at least a first spherical shoe having at least a first guide surface. The gib includes at least a first sliding surface opposite the first guide surface. During operation, the spherical shoe rotates relative to the slide to provide automatic planar alignment between the first guide surface and the sliding surface. A wedge supports the gib to allow rapid and easy alignment with the slide.

Slide guide device for presses

A slider link press includes an oscillation link operating about a fulcrum shaft and an eccentric crank pin. A connecting link connects the oscillation link to a slide. The oscillating link and fulcrum shaft act to increase press torque, reduce downward press speed, and increases upward press speed thereby maintaining cycle time. The eccentric crank pin operates the oscillation link, aids in torque increase, and provides reciprocating movement to the slide. The slide includes pivotable slide gibs that engage reciprocal fixed gibs to maintain parallel surface contact and absorb and eliminate eccentric loads on the slide and the press. Stays and spacers align sides of the press and eliminate flexing under load while absorbing and distributing deformation pressure.
