Abstract (en)
[origin: EP1792669A1] The present invention provides a punch device for U-press in a UOE steel pipe manufacturing process capable of coping with various manufacturing pipe sizes and reducing the width of a U-shaped pipe after U-press less than that by a conventional punch device for U-press. The punch device (100) used in the UOE steel pipe manufacturing process comprises a first punch part (10) having semi-cylindrical press faces (11), (11) on both side-faces, a second punch part (20) disposed in contact with the lower side of the first punch part (10) and having semi-cylindrical press faces (21), (21), which are the same as or different from the press faces (11), on both side-faces, and a third punch part (30) disposed in contact with the lower side of the second punch part (20) and having a downward semi-cylindrical press face (31).
