The description and the figures below offer, in a nonlimiting way, a particular method for using the invention. FIG. 1 shows, from a 's-eye view, a cold rolling Pilger mill which makes possible the use of the process according to the invention.
This pilger rolling process is called roto-rolling and in which a pipe is passed between the rocking set of the outer die and the hardened mandrel on the inside of the pipe. Accordingly, the tube cross-section is reduced while the length and strength are increased. In this respect, this process is similar to the drawing technique.
Cold pilger mill mandrel is an important spare part for cold pilger machine. Pilger tools include in rolling dies and mandrel, dies are used to forming out diameter of finished tubes, and mandrels are used to forming inner diameters. Pilger dies and mandrels are important tools of tube mill.
