Abstract

A press machine adapted for the production of many different types of products in limited quantities. The press machine comprises a plurality of lower dies mounted on a bolster and a plurality of upper dies each mounted to a slide facing to the respective lower dies. Each upper die is mounted to the slide by means of a die clamper via an adapter plate and each upper die is biased upwards by coil springs so that a predetermined gap exists between each pair of upper and lower dies when the slide is moved down to a bottom dead center. An activating plate can be insertable between the slide and each adapter plate so that the activated upper die is allowed to make contact with the opposing lower die.
