The invention relates to a bipolar plate forming technology, in particular to super-plastic forming device and process of a
metal bipolar plate for a
proton exchange membrane fuel
cell. The device comprises a pressure plate, guide sleeves, springs, guide posts, a pressing rod, an environmental box, an upper template, a lower template, a base, a connection plate, a blank pressing plate, a
metal plate and a support rod. The process implemented by the device comprises the following steps: (1) opening the environmental box; (2) fixing a
metal sheet of a processed part on the lower template; (3) closing the environmental box, determining the super-plastic forming temperature according to a processed plate and inputting the super-plastic forming temperature into a
control system; (4) setting the
stroke and the movement rate of the upper template according to the super-plastic
strain rate and flow channel shape of the processed plate; (5) starting a circuit
system and the environmental box, starting a pressure forming
machine to move downwards, and finishing
stamping; (6) starting the upper template of a press to reversely return back to the initial position; and (7) opening the environmental box, and cooing and taking out a formed part. According to the super-plastic forming device and process, the material is effectively prevented from rebounding, and the forming accuracy and the dimensional accuracy are ensured.
