Abstract

<B>"EQUIPAMENTO HIDRáULICO PARA ESTAMPAGEM EM PROFUNDIDADE"<D>. A invenção se refere a um equipamento hidráulico para estampagem em profundidade em prensas para estampagem de partes moldadas de chapa com o qual seja possível uma estampagem em profundidade reprodutível aos mais distintos parâmetros operacionais, como propriedades de material, engraxamento, lubrificação, temperatura, etc., no que concerne a forma e qualidade da peça de trabalho, sem que seja necessária uma correção manual constante, por exemplo pela intercalação de lascas de papel. Esse objetivo é alcançado, de acordo com a invenção, pelo fato de que a força de retenção para a estampagem em profundidade da peça de trabalho (19) está dividida em uma coroa ativa (25) exterior e uma coroa ativa (26) interior, sendo que a coroa ativa (25) exterior é ativada hidraulicamente com uma carga de base ajustável a partir dos cilindros de retenção de chapa (13) e atua sobre a placa de base de ferramenta (11), enquanto que os pontos ativos atuam com as botões de pressão/forma (5; 20) da coroa ativa (26) interior sobre a placa de retenção de chapa (10) e são ativáveis reguladamente intencionalmente respectivamente individualmente ou em grupos.
