METHOD FOR HOT STAMPING FORMING OF COMPLEX TOLERIE COMPONENT PIECES OF COMPOSITE MATERIAL AND TOOLING FOR IMPLEMENTING IT

摘要

The object of the invention is a process for forming by hot stamping of complex sheet metal parts consisting of a one-piece element comprising several parts of relatively thin thickness arranged in different secant planes, starting from a blank (6) consisting of at least one ply of fibers pre-impregnated with a thermoplastic resin, wherein said pre-heated blank (6) is shaped into a set comprising a punch (5) and a die (4) , characterized in that: - in a first step, the portion of said blank (6) to constitute the bottom (2) or the like of the part to be obtained (1) is pressed against the bottom (4a) of the die (4) then, in a second step, the portion or portions of the blank (6) constituting the one or more fallen edges (3) of said piece are pressed against the flanks of the die, the blank thus obtained then being demolded. / P
