Abstract

Sposób kształtowania tulei, zwłaszcza cienkościennych, prowadzi się tak, że przed umieszczeniem profilu wyjściowego pomiędzy matrycami kształtującymi ten profil wyjściowy umieszcza się pomiędzy jednownękową matrycą górną (2) i jednownękową matrycą dolną (1) narzędzia do kształtowania tulei posiadającymi na każdej ze ścian wnęki (3) dwa wybrania (4), z których każde utworzone jest od naroża wnęki (3) do jej środkowej części pod kątem (α) ostrym o wielkości od 3° do 6°. Matrycę górną (2) i matrycę dolną (1) przemieszcza się do siebie i kształtuje się profil wstępny, który następnie, po rozsunięciu tych matryc (1, 2), wyciąga się. Profil wstępny umieszcza się następnie pomiędzy matrycami kształtującymi.The method of shaping sleeves, especially thin-walled ones, is carried out in such a way that before placing the output profile between the dies shaping this output profile, tools for shaping sleeves are placed between the one-cavity upper die (2) and the one-cavity lower die (1) with tools for shaping the sleeves having cavities (3 ) two recesses (4), each of which is formed from the corner of the recess (3) to its central part at an acute angle (α) of 3° to 6°. The upper die (2) and the lower die (1) are moved towards each other and the initial profile is formed, which then, after the dies (1, 2) are pulled apart, are pulled out. The pre-profile is then placed between the shaping dies.
