Abstract
Parts with high surface finish are removed from tools of a fine blanking press with accuracy and at high speed. The press has high opening and shutting speeds achieved by a direct drive having high acceleration power, a high turning moment, and small construction dimensions. A cross slide is movable transverse to a working direction of tool parts and is fixed at a frame of the direct drive. The direct drive includes a drive shaft which changes turning direction based on the stroke of a ram that is pivotally connected to the cross slide via an arm, a bracket, and a rapid-action coupling. Rotating motion is converted into a linear motion, which reverses between a rear stop position and a front stop position of the cross slide in a working area.
