Abstract

Prensa mecánica adaptada para procesos de conformado, que comprende un troquel superior y un troquel inferior adaptados para conformar una pieza entre ambos, un motor para provocar el desplazamiento de al menos uno de ellos con respecto al otro, un cigüeñal acoplado al motor, y un mecanismo que transforma el movimiento rotatorio del cigüeñal en un desplazamiento lineal de dicho troquel. La prensa comprende además una cámara hidráulica (4) para amortiguar o absorber posibles sobrecargas durante el conformado, y un dispositivo actuador para provocar que al menos parte del fluido presente en la cámara hidráulica (4) se descargue cuando la prensa está en un punto muerto inferior en el que se conforma la pieza entre los troqueles, y que al menos parte de dicho fluido retorne a la cámara hidráulica (4) una vez la prensa abandona el punto muerto inferior.
