    • A manually operable press comprises a manually pivotable actuating lever for effecting a forward press stroke and a return stroke of a press slide. A mechanical return stroke interlock inhibits a return movement of the press before the press slide has come to a lower end position of the press stroke. A cam plate within said return stroke interlock is connected for being pivoted together with the actuating lever. The cam plate has a groove-shaped guide cam provided with a plurality of lock protrusions. A spring-biased lock pin runs along the guide cam and is adapted to run freely along the guide ram in an operational direction but is inhibited by the lock protrusions within the guide cam from running in a direction opposite the operational direction. An opening each is provided in the guide cam at the lock protrusions. Unlocking pins are provided in each of the openings. The pins are adapted to be actuated from outside the press for bringing the lock pin out of engagement with the lock protrusions thus allowing the lock pin to run in the opposite direction when the unlocking pins are actuated.
    • 手动操作的压力机包括可手动枢转的致动杆,用于实现压力机滑块的向前冲压行程和返回行程。 机械返回行程互锁在压力机滑块进入冲压行程的下端位置之前禁止压机的返回运动。 所述返回行程联动装置内的凸轮板被连接起来以与致动杆一起枢转。 凸轮板具有设置有多个锁定突起的槽形引导凸轮。 弹簧偏置的锁销沿着导向凸轮延伸并且适于在操作方向上沿导向柱塞自由运动,但是被引导凸轮内的锁定凸起阻止在与操作方向相反的方向上运行。 在所述锁定突起处的所述引导凸轮中设置有开口。 在每个开口中设置解锁销。 这些销适于从压机的外侧致动,以使锁销与锁定突起脱离接合,从而当解锁销被致动时允许锁定销沿相反方向运行。
