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

Abstract

An actuating assembly for a hold down arrangement of a can bodymaker includes a cam body having a cam surface rotatably coupled to a frame of the bodymaker and a swing lever having: a main portion having a first end pivotably coupled to the frame of the bodymaker and a second end 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 and engaged with the cam surface. The actuating assembly also includes a sensing arrangement including a controller and a number of sensors in communication with the controller. 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.
