摘要： A special roller machine for a metal polar plate. A box body is a square with a circular through hole in the middle part. Upper and lower pressing rollers are mounted in the circular through hole; the upper and lower pressing rollers are mounted in grooves formed in the lower sides of upper and lower sector rotating bodies through bearing seats and are connected with upper and lower rotating blocks respectively; the rotating blocks are symmetrically arranged and are connected with upper and lower servo electric cylinders through connecting rod mechanisms respectively, then the pressing rollers are finely adjusted; four identical arch-shaped plates are mounted on the inner surface of the circular through hole for locating the rotating blocks; and main transmission is implemented in such a way that a servo motor drives the lower pressing roller to move through a safety coupling, a reduction gearbox and a cross coupling.
