Abstract

The press (2) comprises a housing (4) in the forward part of which a slide ram (22) is mounted on bearings (62). The ram (22) is driven by an electric motor (26) by way of reduction gear box (24), having an output shaft (79) to which is eccentrically mounted a stub shaft (78) surrounded by a roller bearing ring (80) in a bearing block roller (82). As the output shaft (79) is rotated by the motor (26), the roller (82) rolls back and forth along a guideway (74) formed in the rear face of the ram (22), to take up the eccentricity of the shaft (78). The ram (22) is centrally mounted in its bearings (62) to avoid its canting as it is driven.
