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.The tool for forming square pipes, especially thin-walled ones, has the form of two shaping rolls with a V-shaped working profile (3), which on each of its surfaces has a recess (4), which is formed from one corner of this working profile (3) to its other corner . The recess (4) has the shape of a sector of a circle with a radius (r) ranging from 2.8 to 4.8 times the height (a) of the shaped pipe.
