Abstract

Narzędzie do formowania rur kwadratowych, zwłaszcza cienkościennych ma postać dwóch walców kształtujących z profilem roboczym (3) V-kształtnym, który na każdej jego powierzchni ma wybranie (4), które utworzone jest od jednego naroża tego profilu roboczego (3) do jego drugiego naroża. Wybranie (4) ma kształt wycinka koła o promieniu (r) o wielkości od 2,8 do 4,8 razy większej od wysokości (a) kształtowanej rury.
