ABSTRACT:
An automated system for forcibly dismantling used power transformers so that their metal constituents may be recovered for recycling. A rigid, generally cubicle frame is supported upon a suitable concrete floor. A cutting carriage is independently suspended from suitable rails attached to the frame for slidable movements toward or away from a receiving station into which transformer to be processed are conveyed. The cutter carriage includes a removable cutter blade configured to compressively shear transformer windings. The cutter carriage cooperates with a reciprocating attack carriage which is slidably suspended for independent movements toward or away from the receiving station. The attack carriage comprises an attack blade having at least one outwardly projecting penetrator which initially stabs and captures transformer to be processed. Both carriages may be hydraulically moved towards or away from each other. The attack carriage is preferably suspended from the cutter carriage. When compressed together shearing elements associated with the cutter blade and a specially configured attack plate quickly cut through transformers to aid in the recycling of their metal cores and windings. Transformers delivered to the receiving station may be lifted into a vulnerable attack position by an elevator. After a transformer is conveyed to the receiving station, it is preferably braced by a pusher plate prior to penetration by the attack system.
