Abstract

Sposób formowania rur kwadratowych, zwłaszcza cienkościennych prowadzi się tak, że w pierwszym etapie profil wyjściowy umieszcza się pomiędzy walcem kształtującym górnym (1) i walcem kształtującym dolnym (2) posiadającymi na każdej ze ścian profilu roboczego (3), od jednego naroża tego profilu roboczego (3) do jego drugiego naroża, wybranie w kształcie wycinka koła o promieniu (r) o wielkości od 2,8 do 4,8 razy większej od wysokości (a) kształtowanej rury.The method of forming square pipes, especially thin-walled ones, is carried out in such a way that in the first stage the output profile is placed between the upper shaping roll (1) and the lower shaping roll (2) having a working profile (3) on each of the walls, from one corner of this working profile. (3) to its second corner, cutting in the shape of a sector of a circle with a radius (r) of 2.8 to 4.8 times the height (a) of the shaped pipe.
