Method of manufacturing axially symmetrical hollow components

摘要

The method involves clamping a pipe (9) in a pressure rolling machine (10) and carrying out in-rotation displacement, affecting radial feed of at least one roller (22,32) onto the rotating pipe, and local drawing-in of the pipe through the pressure rollers. Simultaneous forming of the base area (42) of a first hollow component (40) is then carried out on one side of the roller, followed by simultaneous forming of a top area (41) of a second hollow profile on the other side of the roller.
