Metal flow field plate processing unit (plant) in the prior art makes the top that micro shaping die head is arranged in metal plate, leads to
Micro shaping die head is crossed to be pressed downward to make metal plate extrusion forming.The metal flow field plate that such processing unit (plant) actual processing comes out
Uniform flow passage is poor, to affect the performance of Proton Exchange Membrane Fuel Cells obtained.
Inventor thinks by analysis, and when metal plate is horizontally arranged, since only periphery is fixed, centre does not have supporting point,
So there are subtle differences in height between middle section and peripheral portion under the gravity effect of itself.Micro shaping die head
The amount pushed during extrusion forming be it is fixed, this allows for the depth of the runner processed, and there are inconsistent feelings
Condition, that is, the depth of the runner on metal flow field plate close to surrounding is deeper, and the depth of the runner in middle position is shallower.Meanwhile by
It being fixed in the position on metal plate periphery, the mobility of material is relatively poor compared with middle section, so it is extruded together it
After be less likely to occur to spring back.And on the one hand degree that the metal material of middle section is extruded is shallower, the stream of another aspect material
Dynamic property is relatively more preferable, so being easy to happen rebound, and then the situation of runner depth unevenness is further aggravated.If solving this
Problem, one of technical solution are to carry out precision control by the device of precision control depression distance, to improve runner depth
Shallow uneven situation.But micro-molding technology is exactly to be operated on millimeter even micron level originally, on this basis

Shift value.When in use, since the two sides of metal plate 4 are fixed, and centre does not have above-mentioned metal flow field plate processing unit (plant)
Have a supporting point, thus intermediate portion by its own gravity and generate subtle difference in height with peripheral portion.When lower section
When micro shaping die head 39 presses upwards, relatively 4 peripheral portion of metal plate of the two of the pressure on top surface that 4 middle section of metal plate is subject to is omited
It is more.Again since 4 periphery of metal plate is fixed, the material of peripheral portion mobility in processing is relatively poor, does not allow
Easily spring back；And the mobility of middle section is relatively preferable, the power of rebound is slightly more more than peripheral portion.Pass through metal plate
The rebound effect of 4 different location of metal plate after the self gravitation effect of 4 different locations, and processing, the two collaboration, so that finally
The depth of the runner processed is more uniform consistent, and then improves the water conservancy diversion of flow-field plate, gas distribution and drainage performance.
