Abstract

La invención se refiere a un cojín de estampado hidráulico (17) para una prensa de estampado (10). El cojín de estampado hidráulico (17) comprende por lo menos un cilindro hidráulico (21) que comprende un vástago de pistón (27) que genera una fuerza total (G) para actuar sobre el anillo de sujeción de la lámina de metal (20). El cilindro hidráulico (21) comprende un circuito de trabajo hidráulico (37) por medio del cual puede generarse una fuerza de trabajo hidráulica (A) en una dirección de trabajo (Z) para actuar sobre la parte* de anillo (28) del pistón (26) al cual puede aplicarse una fuerza sobre ambos lados. Independiente de la fuerza de trabajo (A) generada por el circuito de trabajo hidráulico (37) para actuar sobre el pistón (26) del cilindro hidráulico (21), una fuerza de muelle (F) actúa sobre el pistón (26). La fuerza de muelle (F) es generada mediante un dispositivo de muelle (45). La fuerza de muelle (F) no se controla ni se ajusta, pero se fija previamente. Preferiblemente, la fuerza de muelle (F) es exclusivamente una función de la posición o ubicación del pistón (26) con respecto a la carcasa del cilindro (25). La fuerza total (G) que actúa sobre el pistón (26) es el resultado de la suma de los vectores de la fuerza de trabajo (A) y de la fuerza de muelle (F).
