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.Mechanical press adapted for forming processes, comprising an upper die and a lower die adapted to form a piece between them, an engine to cause the displacement of at least one of them with respect to the other, a crankshaft coupled to the engine, and a mechanism that transforms the rotational movement of the crankshaft into a linear displacement of said die. The press further comprises a hydraulic chamber (4) to dampen or absorb possible overloads during forming, and an actuator device to cause at least part of the fluid present in the hydraulic chamber (4) to discharge when the press is in a neutral position bottom in which the piece is formed between the dies, and at least part of said fluid returns to the hydraulic chamber (4) once the press leaves the bottom dead center.
