Title (EN) PRESSING TOOL FOR PRESS HARDENING AND THE USE THEREOF FOR PRODUCTION OF PRESS HARDENED SHEET METAL COMPONENTS
(FR) OUTIL DE PRESSAGE POUR LE DURCISSEMENT À LA PRESSE ET SON UTILISATION POUR LA PRODUCTION DE COMPOSANTS EN TÔLE DURCIE À LA PRESSE
Abstract:
(EN) The invention refers to a pressing tool (200, 200') for press hardening. The pressing tool comprises a first die (20) and a second die (22), the first and second dies (20, 22) having a forming surface together defining a forming cavity. At least one of said first and second dies (20, 22) comprises a core (24) forming a body of a metallic material having a heat conductivity of at least 110 W/mK, and a shell (25) connected to the core (24) and forming the forming surface of of said first and second dies (20, 22). The shell (25) is formed of a material having a heat conductivity less than 100 W/mK.
(FR) La présente invention concerne un outil de pressage (200, 200') pour le durcissement à la presse. L'outil de pressage comprend une première matrice (20) et une seconde matrice (22), les première et seconde matrices (20, 22) ayant une surface de formation respective définissant conjointement une cavité de formation. La première et/ou la seconde matrice (20, 22) comprennent un noyau (24) formant un corps d'un matériau métallique ayant une conductivité thermique d'au moins 110 W/mK, et une coque (25) raccordée au noyau (24) et formant la surface de formation desdites première et seconde matrices (20, 22). La coque (25) est fabriquée dans un matériau ayant une conductivité thermique inférieure à 100 W/mK.
