Abstract
A wire cage making machine includes a pair of rod supporting wheels decoupled from one another and capable of being rotated by respective motors at different speeds and/or directions to control the contour of a wire cage, such as twisting the rods. The machine includes a carriage to which the wheels are mounted, with one of the wheels maintained at a fixed position on the carriage and the other wheel movable along rails of the carriage. A welding head is positioned proximate the stationary wheel and is connected to the carriage by a pivot arm that allows the welding head to be moved closer to or farther away from the center of the stationary wheel. The pivot arm allows the position of the welding head to be moved in response to changes in radial positions of longitudinal rods carried by the wheels and to which wire is welded, to join the rods together to form a wire cage. The rods are held by clamps mounted to spokes of the wheels. The radial position of the clamps of the stationary wheel can be moved in real-time to change the diameter of the wire cage.
