Device for step-by-step transport of workpieces through the processing area of a forming machine

摘要

The device has a lifting bar (2) formed with a gripper rail (4). Drive units (8, 9) of lifting systems (12, 13) are formed with a swinging housing (27) rotatable on an axle. A rocker arm (28) is driven at the bar and supported rotatably around 90 degrees in the housing. The housing is engaged with an internal gear segment (30a) or an external gear segment (30b) for horizontal movement of the bar in a transportation direction in a pendulum manner. The arm is engaged with an internal gear segment or an external gear segment for moving the bar transverse to the direction in a pendulum manner.
