Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 2 and 5, the apparatus for processing a metal bipolar plate of a fuel cell with a high aspect ratio according to the present invention includes a lower mold plate 10, an upper mold plate 20, a metal sheet mounting block 30, a plurality of pressing blocks 40, a limiting plate 50, a material blocking block 60, and a guide pillar 70.
The upper surface of lower bolster 10 is sunken to be provided with a plurality of shaping grooves 11, and spacing breach 13 has been seted up to the one end of lower bolster 10, and at least two first guide post holes 12 have been seted up to one side of lower bolster 10. The bottom of the guide post 70 is embedded in the first guide post hole 12.
A plurality of through grooves 21 are formed on the upper die plate 20 at positions corresponding to the plurality of forming grooves 11, and a second guide pillar hole 22 is formed on one side of the upper die plate 20 corresponding to the first guide pillar hole 12. When the upper plate 20 is placed on the lower plate 10, the tops of the guide posts 70 are located in the second guide post holes 22.
The upper die plate 20 is provided with a material blocking groove 24 at one side of the through groove 21. The dam block 60 is movably positioned in the dam tank 24.
The upper surface of sheetmetal installation piece 30 has seted up the mounting hole, and the mounting hole inlays and is equipped with spacing post 31, and the top salient in mounting hole of spacing post 31.
The pressing block 40 is positioned in the through groove 21 and movably extends into the forming groove 11. The middle part of the pressing block 40 is provided with a middle opening 41.
The position limiting plate 50 movably passes through the middle openings 41 of the plurality of pressing blocks 40.
Referring to fig. 3 and 4, in use, a through hole 120 is drilled at one end of a metal sheet 101, such as a stainless steel sheet, and the limiting post 31 of the metal sheet mounting block 30 passes through the through hole of the metal sheet 101, so that one end of the metal sheet 101 is fixed relative to the lower mold plate 10. Pushing the metal sheet mounting block 30 into the position of the limiting notch 13 of the lower template 10; the upper platen 20 is moved upward a distance relative to the lower platen 10 such that a gap is formed between the upper platen 20 and the lower platen 10, and the metal sheet 101 is pushed into the gap between the upper platen 20 and the lower platen 10. As indicated by arrow a in fig. 3.
The blocker block 60 is then inserted into the blocker slot 24 and positioned over the metal sheet 101. The stop block 60 is a flexible material that functions to secure the metal sheet 101 and prevent the metal sheet 101 from being crushed. When the pressing block 40 is pressed for the first time, the material blocking block 60 plays a certain material blocking role, and the metal sheet can flow into the lower template 10 from the movable end conveniently.
The pressing blocks 40 are inserted into the through grooves 21, respectively, and are in contact with the metal sheet 101.
The pressing blocks 40 sequentially move downwards under the action of manual or external downward pressing driving units according to the sequence from the fixed end close to the metal sheet to the fixed end far away from the metal sheet, and drive the metal sheet 101 to extend into the forming groove 11 together, so that the metal sheet 101 is pressed into a concave-convex flow channel structure.
After each pressing block 40 extends into the forming groove 11, the limiting plate 50 moves forward a distance in a direction away from the fixed end of the metal sheet and penetrates through the middle opening 41 of the pressing block 40 to fix the pressed pressing block 40, so as to prevent the part of the metal sheet 101 pressed into the runner structure by the subsequent pressing block 40 from tilting upward during pressing, and drive the pressing block 40 extending into the forming groove 11 to move upward, so that the part of the metal sheet 101 which is formed before is deformed. The moving direction of the stopper plate 50 is shown by an arrow b in fig. 3.
In the process, as the metal sheet 101 deforms in response to the forming groove 11, the portion of the metal sheet 101 away from the metal sheet mounting block 30 contracts toward the stopper column 31 and enters the gap between the upper die plate 20 and the lower die plate 10.
Referring to fig. 1, after the metal sheet 101 is formed by the processing device of the fuel cell metal bipolar plate with a high aspect ratio of the present invention, a flow channel structure 110 with a concave-convex shape is formed in the middle. The metal sheet 101 is also punched with air holes 130 at both ends by other punching means.
Compared with the prior art, the processing device of the fuel cell metal bipolar plate with high aspect ratio of the utility model comprises a lower template 10, an upper template 20, a metal sheet mounting block 30, a plurality of pressing blocks 40, a limiting plate 50 and a guide pillar 70; the upper surface of the lower template 10 is concavely provided with a plurality of forming grooves 11, and the guide posts 70 are arranged on one side of the upper surface of the lower template 10 in a protruding manner; a plurality of through grooves 21 are formed in the upper die plate 20 in a penetrating manner at positions corresponding to the plurality of forming grooves 11, a second guide pillar hole 22 is formed in one side of the upper die plate 20 corresponding to the guide pillar 70, and the guide pillar 70 is located in the second guide pillar hole 22; the upper surface of the metal sheet mounting block 30 is provided with at least two limiting columns 31 in a protruding manner, and the metal sheet mounting block 30 is positioned on the outer side of one end of the lower template 10; the pressing block 40 is positioned in the through groove 21 and movably extends into the forming groove 11; the middle part of the pressing block 40 is provided with a middle opening 41; the position limiting plate 50 movably passes through the middle openings 41 of the plurality of pressing blocks 40.
