Abstract
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.
