PROCEDE DE FABRICATION D'UN CORPS DE BENNE A PROFIL CONCAVE

摘要

A method for forming a one-piece skip body with a concave cross section from a large metal sheet (1) by imparting an approximate cross section to the sheet using shaping mechanisms (2) is disclosed. According to the method, the approximate cross section is maintained while a sealing plate (10) is secured to one end (9) and a stiffening reinforcement member (13) shaped according to the final cross section is attached to the other end (12). The longitudinal edges are stiffened then the most curved areas are mechanically treated and the shaping mechanisms (2) are released. The method is relevant to skip manufacturers and more generally to builders of utility vehicles.
