ABSTRACT:
A press having a machine frame section (10) and a movable section capable of reciprocal movement in a vertical direction relative to the machine frame section, for making products using a pair of dies. The movable section includes a slide (24) to which one of the pair of dies is mounted, and a horizontal guide surface is formed on one of the machine frame section and the movable section. A drive slider (51, 52, 53, 54) has a horizontal sliding surface facing the horizontal guide surface and an inclined sliding surface inclined at a specified angle, and is movably joined to the one of the two sections. A swash plate (51, 52, 53, 54) has an inclined guide surface facing the inclined sliding surface, and is fixed to the other of the two sections. A linear motor (1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b) causes the drive slider to reciplocate along the inclined guide surface of the swash plate through a larger stroke. Energy of the reciprocating drive slider causes the slide to vertically reciplocate through a smaller stroke with a larger pressure.
