The invention discloses an integrated mixed-drive double-cylinder series booster
hydraulic press, which belongs to the field of
forging equipment. It replaces the
driving mode of the three-phase asynchronous motor with the
driving mode of the
servo motor, and applies the transmission mode of the
ball screw nut pair of the electric
screw press to the traditional
hydraulic press. First, it makes the traditional
hydraulic press achieve faster
stroke and return speed requirements, the rapid
forging frequency of the traditional hydraulic press is increased; secondly, the
servo drive technology improves the response speed, precision, and process flexibility of the
control system, expands its process range, saves energy and reduces consumption, and simplifies the structure of the traditional hydraulic
system; again , replacing the one-way
plunger cylinder structure of the traditional hydraulic press with a double-cylinder series-type supercharged single-pass
plunger cylinder, which can realize the pressurization effect and improve the
forging efficiency; finally, the AC
servo motor drives the screw nut pair to move, eliminating the need for the traditional press. The return cylinder and return structure of the press make the structure of the press simple and the load of the movable beam is small.
