Abstract

A workpiece turning device is provided for an automated press train of the type where workpieces are turned after being withdrawn from a working chamber of a press and are then subsequently fed to a further press. The turning device includes separately movable gripper arms for clamping a workpiece therebetween, as well as a rotary unit for rotating the gripper arms as a unit about an axis parallel to the plane of clamping movement. In preferred embodiments the gripper arms are actuated by piston-cylinder units connected to a pressure source by a rotatable connection.
