Method of shaping by stamping a hot parts of complex tolerie in composite material and tooling for implementing it.

摘要

- the object of the invention is a process for forming by hot stamping sheet metal parts of complex consisting of a one-piece element comprising several parts of relatively small thickness, arranged in different planes intersecting, from a blank (6) consisting of at least one ply of fibers pre - impregnated with a thermoplastic resin, in which the said blank (6), previously heated is placed in the form of an assembly comprising a punch (5) and a matrix (4), characterized in that: - in a first step, the part 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 matrix (4), then - in a second step, the blank parts (6) constituting the flanges (3) of said part, are pressed against the sides of the matrix, the blank thus obtained then being demolded.
