The side of described arrangement for adjusting height is provided with fastener, and described fastener comprises fastening screw pit and holding screw, undertaken by holding screw double thread post fastening, guarantee adjust after threaded post can not be moved in use.
The edge of a knife on described knife edge due can seal.
The method that apparatus of the present invention are removed for bipolar plates dowel, comprising: according to the knife edge due of the shape of the dowel that will excise in bipolar plates and distribution situation preparation excision use, be provided with the first location hole with bipolar plates location use on knife edge due; Bipolar plates below arranges places flat board, and the position of placing dull and stereotyped corresponding each dowel is provided with arrangement for adjusting height; By knife edge due, as for bipolar plates top, and bipolar plates retrains by backstay, guarantees that the edge of a knife is placed into the dowel place that will excise accurately; By placing the arrangement for adjusting height on flat board, in adjustment bipolar plates, each dowel is consistent with the height of the edge of a knife in knife edge due plane; Finally excise dowel.
Compared to the prior art, beneficial effect of the present invention:
Apparatus of the present invention are simple in structure, structure is reasonable, and the muscle that can accurately be located by connecting excision position is used apparatus of the present invention excision dowel, incision site homogeneous, notch depth is suitable, can greatly improve operation controllability, guarantee product quality and qualification rate, improved production efficiency.

Embodiment
By specific embodiment, the present invention is further expalined to explanation.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, bipolar plates 1 is provided with dowel 13 and oxidant turning part 14, fuel gas turning part 15 and cooling agent turning part 16.A kind of dual polar plates of proton exchange membrane fuel cell dowel removal device, comprises bipolar plates, and bipolar plates is provided with location hole 9, dowel 13 and oxidant turning part 14, fuel gas turning part 15 and cooling agent turning part 16.A kind of dual polar plates of proton exchange membrane fuel cell dowel removal device, comprises knife edge due 2 and for placing the placement flat board 3 of bipolar plates 1, and described knife edge due 2 is provided with the edge of a knife 12 of preparing according to the shape of the dowel that will excise in bipolar plates and distribution situation; Described position of placing the each dowel of corresponding bipolar plates on dull and stereotyped 3 is provided with arrangement for adjusting height; Described knife edge due 2 is provided with first location hole 10 corresponding with bipolar plates location hole 9, and described placement dull and stereotyped 2 is provided with second location hole 11 corresponding with bipolar plates location hole 9, and described knife edge due 2, placement dull and stereotyped 2 connect by backstay 4.
Described arrangement for adjusting height comprises screwed hole 5 and supporting threaded post 6, and described screwed hole 5 is located at the position of placing corresponding each dowel 13 on dull and stereotyped 3.Be specially: be provided with screwed hole 5 in the position of placing corresponding each dowel 13 on dull and stereotyped 3, in screwed hole 5, place supporting threaded post 6, by regulating the length of threaded post 6 precessions, regulate the height at each dowel 13 places, in adjustment bipolar plates 1, each dowel 13 is consistent with the height of the edge of a knife 12 in knife edge due 2 planes, thereby the knife-edge plane height of compensation knife edge due is inconsistent.The object that arrangement for adjusting height is set be mainly because: at present in the knife edge due course of processing, because the evenness of base plate is lower, cause thus the knife-edge plane height of the knife edge due after machining inconsistent, in the course of processing, can cause the stressed inconsistent of each reinforcement place, produce or part dowel cannot excise or the stressed excessive situation that causes the undue depression of bipolar plates parts plane under dowel in part dowel place.
The side of described arrangement for adjusting height is provided with fastener, and described fastener comprises fastening screw pit 7 and holding screw 8, undertaken by holding screw 8 double thread posts 6 fastening, guarantee adjust after threaded post 6 can not be moved in use.
The edge of a knife 12 on described knife edge due 2 can seal.Because current bipolar plates course of processing operation is more, need to repeatedly position installation, for avoiding because the deviation that when location occurs causes dowel deviation theory position, thereby cause dowel not excise completely, can seal the excision edge of a knife of dowel.
The method that apparatus of the present invention are removed for bipolar plates dowel, comprising: according to the knife edge due of the shape of the dowel that will excise in bipolar plates and distribution situation preparation excision use, be provided with the first location hole with bipolar plates location use on knife edge due; Bipolar plates below arranges places flat board, and the position of placing dull and stereotyped corresponding each dowel is provided with arrangement for adjusting height; By knife edge due, as for bipolar plates top, and bipolar plates retrains by backstay, guarantees that the edge of a knife is placed into the dowel place that will excise accurately; By placing the arrangement for adjusting height on flat board, in adjustment bipolar plates, each dowel is consistent with the height of the edge of a knife in knife edge due plane; Finally excise dowel.
Use apparatus of the present invention excision dowel, incision site homogeneous, notch depth is suitable, can greatly improve operation controllability, guarantees product quality and qualification rate, has improved production efficiency.
