Abstract
A stamping die of a thin-type metal flow field plate for processing fuel batteries comprises a flow field stamping forming die, a blanking forming die and a flanging die, wherein the stamping die is provided with a positioning post, the sizes of the blanking rebates around the blanking forming die and the blanking rebates of fluid inlet and outlet passages on two ends of the flow field plate are 0.1-0.3 millimeter larger than the size of a finished flow field plate, the flanging die has the same shape as the stamping forming die, the periphery of the flanging die and fluid inlet and outlet passage rebates on two ends of the flow field plate are not blanking cutting edges but stamping flanged rebates, the sizes of the stamping flanged rebates around the flanging die and the stamping flanged rebates of the fluid inlet and outlet passages on two ends of the flow field plate are identical to the size of the finished flow field plate, a female die of the flanging die is the flow field surface of the flow field plate, and after a male die is stamped, a turnup convex edge of the male die faces towards the side surface of the flow field. The stamping die of the thin-type metal flow field plate for processing fuel batteries has the advantages that the stamping die has simple structure and is easy to manufacture, the metal flow field plate manufactured by the stamping die has high accuracy, the manufacturing is convenient, and the warping deformation of the manufactured flow field is small.
Description
Technical field
The utility model relates to the Proton Exchange Membrane Fuel Cells technical field, relates in particular to Proton Exchange Membrane Fuel Cells flow field manufacturing technology.
Background technology
In the prior art, the thin metal flow field plate of used in proton exchange membrane fuel cell adopts the direct compression moulding of mould usually.The metal flow field plate of this direct compression moulding of prior art has following deficiency: because pressure distribution is inhomogeneous in the pressing process, make metallic plate produce inconsistent extension, thereby at the inner residual inconsistent stress down of metallic plate, this inconsistent stress can make the flow-field plate after the shaping produce uneven distortion.
Summary of the invention
The purpose of this utility model is according to the flow of metal theory, adds new theory in mould design, reduces the deformation extent of the flow-field plate that punch forming obtains.The technical solution of the utility model is: a kind of diel of thin metal flow field plate used for processing fuel cells, comprise a cover flow field punch-forming mold and a cover stamping-out mould, flow field punch-forming mold and stamping-out mould are provided with reference column, it is characterized in that described diel also comprises a cover flanging die, the size of stamping-out mouth is greater than product stream field plate size 0.1-0.3mm around the described stamping-out mould, the size of the stamping-out mouth of flow-field plate two ends fluid inlet and outlet passage is less than product stream field plate size 0.1-0.3mm, described flanging die is identical with the stamping-out mould shape mould of being made up of die and punch, around the flanging die and fluid inlet and outlet passway, flow-field plate two ends is not the stamping-out cutting edge, but punching press flange mouth, the punching press flange mouth and the product stream field plate of punching press flange mouth and flow-field plate two ends fluid inlet and outlet passage are measure-alike around the flanging die, the die of flanging die is the flow field face of flow-field plate, after the punch punching press, the lug of routing up is towards the side, flow field.
The punch steps of diel of the present utility model is: stamp out metal flow field with punch-forming mold on metallic plate, sheet metal be provided with mould on the reference column corresponding positioning hole, become stamping-out oral area position greater than the semi-finished metal flow-field plate of product stream field plate 0.1-0.3mm with the stamping-out oral area position flange of flanging die with stamping-out mould stamping-out to the semi-finished product metal flow field plate, as follows to the step of metal flow field plate stamping-out oral area position flange:
To become stamping-out oral area position to place on the counterdie of flanging die greater than the semi-finished metal flow-field plate of product stream field plate 0.1-0.3mm with stamping-out mould stamping-out, with reference column and locating hole location, the flow field face of metal flow field be towards die; Start stamping machine, punch is stamped into die, then with the punch return; Take out metal flow field, obtain routing up the metal flow field of the high chimb of 0.1-0.3mm in stamping-out oral area position.
The utility model compared with prior art has the following advantages:
1, diel is simple in structure, makes easily;
2, the metal flow field plate precision height made from this mould is easily manufactured;
3, the flow-field plate buckling deformation of Zhi Zaoing is little.
Description of drawings
The present invention has accompanying drawing 6 width of cloth, wherein:
Fig. 1 is the flanging die schematic diagram,
Fig. 2 is that the master of flanging die counterdie looks schematic diagram,
Fig. 3 is the schematic top plan view of flanging die counterdie,

In the accompanying drawing, 1, flanging die punch, 2, flanging die die, 3, the reference column on the flanging die, 4, the fluid inlet on the flanging die, 5, the flow field on the flanging die, 6, the fluid inlet and outlet that has the semi-finished metal flow-field plate of flange surplus, 7, the locating hole that has the semi-finished metal flow-field plate of flange surplus, 8, the flow field that has the semi-finished metal flow-field plate of flange surplus, 9, the semi-finished metal flow-field plate peripheral flanging surplus that has the flange surplus, 10 have the semi-finished metal flow-field plate fluid inlet and outlet flange surplus of flange surplus.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
The flow field punch-forming mold is a mould of the prior art, the stamping-out mould be around existing blanking die is changed system into stamping-out mouth size and flow-field plate two ends fluid inlet and outlet passage stamping-out mouth size than the big 0.1-0.3mm of existing blanking die.Make flanging die again, flanging die is identical with existing blanking die shape, and just the cutting edge with the stamping-out mouth makes the flange mouth into, the size of flange mouth and product stream field plate measure-alike.
The manufacturing process of flow-field plate is: earlier sheet metal is stamped out the hermetically-sealed construction at flow field and edge, flow field and the import and export mix at two ends, flow field with the flow field punch-forming mold, become the semi-finished product flow-field plate of stamping-out oral area position size with the blanking die stamping-out again greater than product stream field plate 0.3mm, then, with this semi-finished product flow-field plate flanging die punching press flange, big 0.3mm translates into towards the limit of flow field face side projection with stamping-out oral area position size, obtains the finished product metal flow field plate.In punch forming and turn-up process, flow-field plate is provided with locating hole, mould be provided with flow-field plate on the corresponding reference column of locating hole, be used to guarantee the precision of stamping-out and turn-up process.
