The deposited component 04 is now clamped in the device by moving the base and head plates into the closed state, ie moving them towards each other. In the closed state, the pressure stamps 07 are thus in contact with the component 04 at numerous positions.

Abstract

L'invention concerne un dispositif de durcissement de composants de tôle. Le dispositif comprend une plaque de base (01) et une plaque de tête (02), qui sont reliées l'une à l'autre, par l'intermédiaire d'éléments de guidage, de telle sorte que la distance entre elles peut être modifiée, afin qu'un état ouvert et un état fermé puissent être adoptés. Entre la plaque de base (01) et la plaque de tête (02), reste un espace de composant réglable (03), dans lequel un composant (04) à durcir peut être inséré. Un entraînement est prévu pour modifier la distance entre la plaque de base (01) et la plaque de tête (02). De nombreuses paires de pièces de pression (06), constituées chacune d'une pièce de pression de plaque de base (06a) et d'une pièce de pression de plaque de tête (06b), sont fixées, axialement de manière opposée, à la plaque de base (01) et à la plaque de tête (02), respectivement. Au moins une pièce de pression de chaque paire de pièces de pression comprend un piston de pression (07) déplaçable axialement et, par conséquent, la distance axiale entre les extrémités des pièces de pression d'une paire de pièces de pression dirigées l'une vers l'autre peut être modifiée. De nombreuses buses de fluide de refroidissement (08) sont prévues, par l'intermédiaire desquelles un fluide de refroidissement peut être introduit dans la chambre de composant (03) par l'intermédiaire d'un évidement attribué (09) dans la plaque de base (01) ou dans la plaque de tête (02) afin de refroidir le composant (04) à durcir.
