Abstract

The invention discloses longitudinal roller rolling forming equipment and a longitudinal roller rolling forming method for metal polar plate flowing channels of a fuel cell. The forming equipment comprises a linear flowing channel longitudinal roller rolling forming device, a polar plate shearing device, a polar plate transferring device, a U-shaped flowing channel longitudinal roller rolling forming device and a rack, wherein the linear flowing channel longitudinal roller rolling forming device comprises a linear flowing channel longitudinal roller rolling pre-forming device and a linear flowing channel longitudinal roller rolling secondary forming device, and the U-shaped flowing channel longitudinal roller rolling forming device comprises a U-shaped flowing channel longitudinal roller pre-forming device and a U-shaped flowing channel longitudinal roller rolling secondary forming device. According to the method, the linear flowing channel longitudinal roller rolling forming device isadopted to complete forming of the linear flowing channels and sealing grooves which are parallel to the linear flowing channels, and the U-shaped flowing channel longitudinal roller rolling formingdevice is adopted to complete forming of the U-shaped flowing channels and sealing grooves which are parallel to the U-shaped flowing channels. According to the equipment and the method, pre-forming and secondary forming are adopted so that the depth of the flowing channels can be increased, cracking is avoided, moreover, resilience is reduced, and continuous production requirements can be met.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a longitudinal rolling forming device and method for a fuel cell metal pole plate flow channel. Background technique [0002] In the existing metal plate flow channel processing method based on roll forming, the method and equipment for processing the complete flow channel of the metal plate using a single roller pair will lead to extreme cracking and springback phenomenon when processing deeper flow channels. protrude. Contents of the invention [0003] The object of the present invention is to provide a longitudinal roll forming equipment for the metal plate flow channel of a fuel cell. The flow channel of the metal plate is used for pre-forming and secondary forming, which can increase the depth of the processed flow channel and avoid the forming process. Cracks that occur in the process, and reduce the springback of the metal plate flow channel after forming, and can meet the req...
