US 11,724,468 B2 · Method and device for manufacturing a profile member of composite material, the cross-section of which has three branches

Abstract

Method and device for manufacturing a profile member of composite material, the cross-section of which has three branches, including the steps of: —moving together two opposite edges of a panel (2) of sheet material in such a manner that these two opposite edges are juxtapositioned in one juxtapositioning direction; translating a pair of jaws (20) in a direction perpendicular to the juxta-positioning direction in such a manner that the pair of jaws (20) is positioned on either side of the opposite juxtapositioned edges, this translational movement of the pair of jaws (20) being carried out in the direction of a base (25); —simultaneously pressing the sheet material between the two jaws (20), on the one hand, and between the jaws (20) and the base (25), on the other hand; —finishing the profile member of composite material by hardening with a matrix with which the sheet material is impregnated.

Dependent claims

A method for manufacturing a profile made of composite material having a cross section with a vertical part and a horizontal part, the method comprising the steps of:

moving two opposite rims (2A, 2B) of a panel (2) of sheet material toward one another such that the two opposite rims (2A, 2B) are juxtaposed in a juxtaposing direction (9);
moving a pair of jaws (20) in translation in a direction perpendicular to the juxtaposing direction (9) such that the pair of jaws (20) is positioned on either side of said juxtaposed opposite rims (2A, 2B), the movement in translation of the pair of jaws (20) being effected in the direction of a base (25);
simultaneously pressing the sheet material between the two jaws (20) the make the vertical part and between the jaws (20) and the base (25) to make the horizontal part;
completing the profile made of composite material by curing a matrix impregnating the sheet material.

A device for manufacturing a profile made of composite material having a cross section with three branches, the device comprising:

a support frame (1) for a panel (2) of sheet material, the support frame (1) having:
a rigid surround (3) having a central opening for the panel (2) of sheet material;
two holding members (4) designed to take hold of two opposite rims (2A, 2B) of the panel (2) of sheet material;
two levers (7), each supporting one of the holding members (4), the levers (7) being mounted on the rigid surround (3) so as to pivot between an opened-out position in which the holding members (4) are spaced apart from one another and a folded-up position in which the holding members (4) are juxtaposed in a juxtaposing direction (9);
a mold (17) provided with two jaws (20) that are movable with respect to one another between a spaced-apart position and a closed-up position;
a counter-mold (18) provided with a base (25);
the support frame (1) being designed to take up a working position in which it is disposed between the mold (17) and the counter-mold (18),
the mold (17) and the counter-mold (18) being movable with respect to one another, in a direction of translation that is perpendicular to the juxtaposing direction (9), between a mutual spacing position and a clamping position in which the jaws (20) of the mold (17) are in the closed-up position and are disposed so as to face the base (25) of the counter-mold (18).
