The invention relates to a hydraulic forming machine for a metal bipolar plate of a proton exchange membrane fuel cell. The hydraulic forming machine comprises a hydraulic transmission component, a supporting component and a hydraulic forming component, wherein the hydraulic transmission component comprises a hydraulic cylinder, an upper valve nozzle, an upper hydraulic pipe, a side valve nozzle, a side hydraulic pipe, a hydraulic cabinet, a valve bank, a hydraulic pump, an encoder, a motor and a control cabinet; the supporting component comprises a top cap, a stand column, a base and fixing feet; the hydraulic forming component comprises a piston rod, a transmission mold, a hydraulic table, a hydraulic pipe, a rubber sealing ring and a thin plate; the piston rod is fixedly arranged on the transmission mold through a bolt; a groove is formed in the transmission mold; the hydraulic table is arranged below the transmission mold; a rectangular groove is formed in the hydraulic table and is used for mounting the rubber sealing ring; the lower end of the hydraulic table is connected with the hydraulic pipe; and the thin plate is arranged in the middle of the rubber sealing ring. According to the hydraulic forming machine, an edge pressing piece is not needed during hydraulic forming, and forming is performed by means of mold pressing and rubber sealing; and the hydraulic forming machine is simple in structure, low in manufacturing cost, high in adaptability and more efficient to use, and facilitates transportation of equipment.
Description
technical field [0001] The invention belongs to the field of hydraulic forming machines, in particular to a hydraulic forming machine for metal bipolar plates of proton exchange membrane fuel cells. Background technique [0002] Proton exchange membrane fuel cell is a new type of energy device with high energy conversion rate, high power, and no pollution. It is now widely used in new energy vehicles, portable backup energy and other fields. The bipolar plate is one of the important parts of the proton exchange membrane fuel cell. Because the metal bipolar plate has high conductivity and excellent machining performance, it is the first choice for the new type of bipolar plate. Hydroforming can effectively increase the forming limit of parts, and improve the processing quality of complex special-shaped parts. The production cycle is short, the production process is small, the production batch is large, and the processing cost can be effectively reduced. [0003] But at prese...
