Abstract: A square tubing swager is an electromechanically operated swaging machine for square steel tubing powered by an electric motor whose mechanical output is connected to a clutch assembly which operates an angle worm drive. The output of the angle drives dual two strand sprockets. These sprockets are connected through a series of roller chains and additional sprockets which drive four cam cross shafts. These cam shafts are set in four corresponding slide blocks assemblies within a jaw mount. The invention would be provided with various sized jaws for various sizes of square steel tubing. During use, the steel stock is inserted within the jaw area and the motor energized. The jaws then form the steel stock inward allowing the deformed area to be inserted within the hollow cavity of undeformed steel stock of the same size.
