Shaping Of Tube Ends By Bending Or Straightening
(AREA)
Abstract
Improvements in the mechanical devices for bending tubes, of the type based on the displacement of a tube trapped between a pushed organ and a grooved matrix provided with a tangential rectilinear appendix where the tube is held, the organ being pushed and the matrix in conditions of experiencing a relative movement of rotation, associated with an inner male permanently located in the area of bending of the tube avoiding its internal corrugation, characterized in that the pusher member, consisting of a grooved ruler, receives the effort intended to imprison the tube and applying it against the die by means of a plurality of rollers arranged in a row acting on said rule opposite to its grooved part.
