The subject of the invention is a method for connecting elements with a cylindrical outline of external walls, especially pipes, which is used for the connecting of pipes and other elements with a cylindrical outline of external walls. Characterized in that on a mandrel, which is a stencil (2) placed in the spindle (1) of the machine tool, two coaxial cylindrical elements (3, 4) are placed, whereas on the element (4) further from the spindle (1) at least two support-mounted rollers (5) with the radius of the curved working surface of (3-5) mm with the feed of rollers (5) (0.15 - 0.25) mm/rotation and the negative gap of (0.2-0.8) mm with the relative deformation of e = (25 40) %, up to the dislocation of the drawing threshold to the front zone of the element (3) closer to the spindle (1), burnishing of this threshold over the front zone of the element (3) closer to the spindle (1) and rolling it over the front zone of the element (3) closer to the spindle (1). |
