چکیده مقاله |
In this study, stamping and hydroforming process was used to form a 0.1 mm-thick SS316L sheet to produce bipolar plates. The ABAQUS software was used to simulate the processes. A 60-ton hydraulic press was used in the stamping process and 1400 bar hydrostatic pressure unit was used in the hydroforming process. According to the results, a good agreement was observed between the experimental and simulation results. Simulation result of the stamping process showed that sheet metal would achieve the critical thickness at the corners before complete filling of the die in the stamping process and the maximum forming height was about 0.6 mm. Hydroforming process could not form the final height of micro-channel because the thickness of sheet at the die corner achieved the critical values. In addition complete filling of the die by hydroforming process was less than stamping process at the same channel height and also needs high pressure. |
