Abstract

Sposób profilowania rur, zwłaszcza cienkościennych prowadzi się tak, że profil wyjściowy o przekroju okrągłym umieszcza się pomiędzy dwoma walcami kształtującymi (1, 2) narzędzia mającymi profil roboczy (3) V-kształtny z dwoma wybraniami (4) na każdej jego powierzchni, z których każde utworzone jest od naroża tego profilu roboczego (3) do jego środkowej części pod kątem (α) ostrym o wartości od 3° do 6°. Poprzez działanie tych walców kształtujących (1, 2) formuje się profil wstępny, który umieszcza się następnie pomiędzy dwoma walcami i poprzez ich działanie na profil wstępny formuję się rurę.The method of profiling pipes, especially thin-walled pipes, is carried out in such a way that the output profile with a round cross-section is placed between two shaping rollers (1, 2) of the tool having a V-shaped working profile (3) with two recesses (4) on each of its surfaces, from which each is formed from the corner of this working profile (3) to its central part at an acute angle (α) of 3° to 6°. By the action of these shaping rollers (1, 2) a pre-profile is formed which is then placed between two rollers and by their action on the pre-profile a pipe is formed.
