The utility model discloses a theory of operation is:

when the metal bipolar plate straightening device convenient to move is used, firstly, a metal bipolar plate to be straightened is placed on the upper side of the workbench 1; the winder 21 is started to pay off the two steel wire ropes 13, and under the elastic action of the first spring 7, the two movable rods 4 move towards the mutually approaching direction, so that the two clamping plates 5 are driven to move towards the metal double-striking plate, and the metal bipolar plate is automatically fixed at the center of the upper side of the workbench 1;

the hydraulic cylinder 14 is started to drive the connecting plate 24 to move downwards, the connecting plate 24 drives the pressing plate 22 to move downwards through the second spring 23, so that the pressing plate 22 moves to the upper side of the metal bipolar plate, in the process, the second spring 23 can play a role in buffering to prevent the pressing plate 22 from crushing the bipolar plate, and when the pressing plate 22 reaches a set pressure value, the pressure sensor 26 is sensed to send a signal to the hydraulic cylinder 14, so that the hydraulic cylinder 14 drives the pressing plate 22 to move upwards, the bipolar plate is properly flattened, and the straightening of the bipolar plate can be realized;

meanwhile, the hydraulic cylinder 14 drives the two cross rods 16 to move downwards through the fixing sleeve 15, the two cross rods 16 respectively drive the piston plate 18 to move downwards in the air cylinder 19 through the piston rod 17, so that the spray head 20 blows air to the bipolar plate, dust on the bipolar plate is blown off, and the bipolar plate can be cleaned before being straightened;

in the straightening process, because the bipolar plate is flattened by the pressing plate 22, the bipolar plate is changed from bending to straight, the length of the bipolar plate can be changed, and under the elastic action of the first spring 7, the positions of the two clamping plates 5 can be automatically adjusted, so that the bipolar plate is always in a fixed state, the pressing plate 22 is further facilitated to flatten the bipolar plate, and the straightening effect is better.
