Abstract
A mechanical press includes a slider which is reciprocated, through connecting rods, by an oscillating plate oscillating around a driving shaft to obtain a press load. The press further includes a swash plate rotatable with the driving shaft. The oscillating plate oscillates in accordance with the rotation of the swash plate. A plurality of lock pins are concentrically disposed in parallel with the driving shaft on a side of the oscillating plate opposite to the swash plate. Each of the lock pins has a spherical head housed in the oscillating plate so as to make the pins rotatable and axial movable. A slider guide supports the pins and the slider.
