Abstract

Inventia se refera la un mecanism, care se monteaza pe masinile de tras tuburi, în vederea obtinerii tuburilor lungi si cu pereti subtiri prin metoda tragerii. Capul de tragere, conform inventiei, este alcatuit dintr-un corp (1), în interiorul caruia culiseaza trei cilindri hidraulici (2), prevazuti cu câte o rola de tragere. Reglarea diametrului de lucru se realizeaza cu motoare de curent continuu (6), care antreneaza câte un ax (7), ce roteste o piulita (8), fixata pe acesta cu o pana (9) si un inel (10)..Piulita (8) se poate deplasa pe o tija filetata (11) rigid fixata pe cilindrul hidraulic (2) cu o piulita (12).
