Step 4：Punch-pin, which continues to move downward and starts extruding, is placed in soft mode appearance inframe soft mode I and soft mode II, and soft mode II is produced
Raw buffer brake simultaneously supports soft mode I, due to the good fluidity of soft mode I, is gradually filled with blank under the action of compressive stress of soft mode II
Punch-pin die cavity；
Step 5：When forcing press runs to displacement set in advance or load, then pressurize 1-3 minutes sheds punch-pin load
Lotus, now fuel battery metal double polar plate component forming finish；
Step 6：Punch-pin is moved upwards under the driving of forcing press, and calm inframe takes out part, so as to obtain up-to-standard
Metal bipolar board member.
Heretofore described sheet metal thickness is in 0.05-0.5mm scopes.
Heretofore described sheet metal can be single-layer metal thin plate or plied timber thin plate, including same
Plant Metal coating and dissimilar metal cladding.
