Abstract
A punch assembly includes a frame that has a pair of arms forming a deep throat for receiving material to be punched, and a single acting punch and die set held by the outer ends of the arms. The punch is actuated with a lever mounting a swing frame that is supported so that when the punch is to be changed, the swing frame can be moved out the way and the punch removed. The die can also be removed when the swing frame is moved away from its working position. The punch can be actuated through the lever either with a manual handle, or with a power actuator.
