This application discloses a parametric design method of a roller tooth profile of a work roll for roll forming of a flow channel of a metal bipolar plate. The method includes: (1) an engagement transmission drawing is plotted according to depth h of the flow channel and a rolling period angle, where h=r−r. A first-half surface of a tooth consists of six segments, where the top surface segment, the upper half segment of the tooth side, the root segment, and the transition segments for the top corner and the root corner are arc curves, and the lower half segment of the tooth side is a straight line. (2) With the center Oof the upper roller as the origin, a transverse end coordinate system is established, and the six segments of the left-half tooth are designed regarding parameters.

Roller tooth profile of work roll for roll forming of flow channel of metal bipolar plate and parametric design method thereof

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.

Special roller machine for metal polar plate

A giant gully-crossing vehicle for polar scientific expeditions, including a gully-crossing bridge and a vehicle body. The vehicle body includes a stage and a travelling portion. The stage includes a top platform, a front bottom plate, a rear bottom plate and a multifunctional lock platform assembly. The front bottom plate and the rear bottom plate are capable of sliding independently relative to the top platform. The travelling portion includes a first travelling component, a second travelling component, a third travelling component, a fourth travelling component, a fifth travelling component and a sixth travelling component which are symmetrically provided at left and right sides of the stage and below the stage. Bridge bodies of the bridge components can be assembled to two gully-crossing bridges, and are connected to the multifunctional lock platform assembly when crossing gullies.
