Description

  The present invention relates to a mechanical press device that reciprocates a movable member using a crank mechanism, and more particularly to a reciprocating rocking mechanical press device.

  Generally, a mechanical press device that performs press processing by reciprocating a movable member by a crank mechanism is configured to convert the energy of circular motion by the crank mechanism into linear motion and use it as thrust (for example, Patent Documents). 1).

By the way, in the press working using the crank mechanism, as shown in FIG. 19, in the circular motion, only a quarter portion (shaded portion E) from 90 ° to 180 ° of 360 ° is used as the applied pressure. Therefore, only one pressurization (processing) can be performed while the crank mechanism is driven once (rotated once). Therefore, the conventional mechanical press device has a problem that the energy of the circular motion of the crank mechanism is not efficiently used as the applied pressure.
