Actuating assembly for a hold down arrangement of a can bodymaker redraw assembly

An actuating assembly for a hold down arrangement of a can bodymaker, the actuating assembly comprising:

• a cam body structured to be rotatably coupled to a frame of the bodymaker so as to be rotatable about a rotation axis by an operating mechanism, the cam body having a cam surface defining a cam path;
• a swing lever comprising:
• a main portion having a first end and a second end opposite the first end, the first end structured to be pivotably coupled to the frame of the bodymaker and the second end structured to be operatively coupled to a redraw assembly of the hold down arrangement;
• and
• a hub portion positioned intermediate the first end and the second end of the main portion, the hub portion engaged with the cam surface of the cam body so as to follow the cam path as the cam body rotates about the rotation axis;
• and
• a sensing arrangement including a controller and a number of sensors in communication with the controller,
• wherein one or more of a portion of the cam body bounded by the cam surface and/or a number of portions of the swing lever are structured to deform in a predetermined manner responsive to the engagement of the hub portion and the surface of the cam body, and
• wherein the controller is structured to determine a force within the actuating assembly from a number of sensed deformations of one or more of the portion of the cam body and/or the number of portions of the swing lever.
