Abstract
Improved device for shaping helical fin tubes characterized in that it consists of a bed that has a pair of head and counterpoint to fasten the tube providing rotational movement, and which has a longitudinal guide rail of a mobile carrier carriage at its end. A pulley through which passes a strip of feeding sheet which descends by one of the sides of the car passing between a set of guide rollers fixed articulately to which they pass in turn between the space delimited between the tube and another sheave paraxial to that which is fixed to a floating forked arm related to a control of the thrust pressure regulation so that when acting on it, it becomes effective to tighten one of the edges of the strip against the lateral surface of the tube and that rotate this and gradually move the trolley to wind the strip in helical organization along the entire lateral surface of the tube in the constitution of the fins, the device also incorporates a generator or converter that supplies the welding current to two electrodes, one of them is mounted swingarm and has a spring so that when acting on that it is kept in erect position ensuring the permanent contact with the lateral surface of the strip, while in the other electrode is applied a spring that presses against the electrode making it impinge against the lateral surface of the tube so that when turning this and go rolling it is pulled in helical organization by the surface side of the tube giving rise to the fins will cause a difference of powers between electrodes such that it makes effective the welding of the strip or the fins in the tube.
