Description

Technical Field

[0001] This utility model relates to the field of metal corrugated plate repair technology, specifically a metal corrugated plate repair structure for rectangular cross-section deformation. Background Technology

[0002] Metal corrugated plates for fuel cells possess excellent electrical and thermal conductivity; they are suitable for large-scale mass production, reducing production costs; they have high mechanical strength, providing reliable support for the membrane electrode assembly (MEA) and contributing to the stability of the fuel cell stack structure; and through innovative coating processes, their corrosion resistance can be significantly improved. While metal corrugated plates offer many advantages, residual internal stress during the actual molding process and uneven heating during coating can lead to bending deformation. This results in deformation of the rectangular cross-sectional shape of the flow channel (e.g., the rectangular cross-section of the flow channel changes to a trapezoidal cross-section), with varying deformation dimensions at different locations. This not only hinders fuel cell stack assembly, causing inconsistent contact areas between the corrugated plate and the diffusion layer during fuel cell stacking, but also leads to uneven temperature distribution during stack operation due to the varying cross-sectional changes at different locations, ultimately degrading fuel cell stack performance. Therefore, an improved metal corrugated plate repair structure for rectangular cross-section deformation is needed to address these issues. Utility Model Content

[0019] Example:

[0020] Please see Figure 1-3 This utility model provides a technical solution: a metal corrugated plate repair structure for rectangular cross-section deformation, including a workpiece recovery and stretching assembly 1, a workpiece placement and positioning assembly 2, a base 3, and a force-applying rod 4. The workpiece placement and positioning assembly 2 includes a second support base 12, a workpiece placement plate 13, a first limiting block 14, a second limiting block 15, a second force-bearing component 16, and a second connecting screw 17. The workpiece placement plate 13 is fastened to the second support base 12 by the second connecting screw 17. The workpiece placement plate 13 is equipped with three first limiting blocks 14 for rapid positioning of the workpiece to be repaired in two directions. The second limiting blocks 15 are four in total and arranged in pairs to achieve positioning and placement of the workpiece to be repaired. The second force-bearing component 16 is aligned with the corrugated groove of the workpiece to be repaired to achieve initial positioning of the workpiece to be repaired. The workpiece recovery and stretching assembly 1 and the workpiece placement and positioning assembly 2 are connected to the upper surface of the base 3.

[0021] Specifically, the rotation of the lead screw 7 is converted into the horizontal movement of the nut 10. The nut 10 has a guide hole and a threaded hole for connecting the tension member 8. The tension member 8 has multiple rows of waist-shaped through holes to facilitate the alignment of the first force-bearing member 9 with the flow channel of the bent part to be restored after placement, so as to realize subsequent actions. The tension member 8 is designed with a circular through hole for connection with the lead screw 7 and the nut 10, and is connected to the lead screw 7 and the nut 10 by screws. The workpiece placement and positioning assembly 2 is mainly used to place the deformed metal corrugated plate with a rectangular cross-section flow channel. The main function of the workpiece placement plate 13 is to place and quickly position the deformed metal corrugated plate. The three first limiting blocks 14 are mainly used to realize the rapid positioning of the deformed metal corrugated plate. The two pairs of second limiting blocks 15 are mainly used for the placement of the second force-bearing member 16 and the alignment of the flow channel near the edge of one end of the deformed metal corrugated plate. It facilitates the later stretching and recovery of deformed metal corrugated plates; multiple threaded holes are designed on the base 3 for connecting and fixing the workpiece deformation recovery stretching component and the workpiece placement and positioning component 2; the force-applying rod 4 can be manually rotated to apply force to the lead screw 7 of the workpiece recovery stretching component 1 to achieve stretching.

[0022] The workpiece recovery tension assembly 1 includes a first support base 5, a guide rod 6, a lead screw 7, a tension member 8, a first force-bearing member 9, a nut 10, and a first connecting screw 11. The guide rod 6 is fixedly connected to the middle of both ends of one side surface of the first support base 5, and the lead screw 7 is threaded through the middle of one side surface of the first support base 5. The nut 10 is threadedly connected to the surface of the lead screw 7, and the force-applying rod 4 is fixedly connected to one end of the lead screw 7. The tension member 8 is arranged between the first support bases 5, and the first force-bearing member 9 is inserted and connected to one end of the upper surface of the tension member 8. The first connecting screw 11 is threadedly connected to the four corners of the upper surface of the first force-bearing member 9, and the total number of the first connecting screw 11 is four.

[0023] Working principle: When using the metal corrugated plate repair structure with a deformed rectangular cross section, firstly, rotate the force rod 4 to rotate the lead screw 7 and move the tensioning component 8 to the position of the principle force-bearing component; then, place the rightmost first limiting block 14 of the positioning component 2 against the workpiece on the right end face of the metal corrugated plate to be repaired; next, place the second force-bearing component 16 between the two sets of paired second limiting blocks 15, and the second force-bearing component 16 must contact the bottom of the flow channel of the metal corrugated plate to be repaired; the next step is to rotate the lead screw 7 through the nut 10 to pull... The extension member 8 is moved to overlap with the component to be repaired in a suitable position. It is necessary to ensure that after the first force-bearing member 9 is inserted from the waist-shaped hole of the extension member 8, it can contact the bottom of the flow channel on the left edge of the component to be repaired as much as possible. Finally, the force-applying rod 4 is rotated again, which rotates the lead screw 7 to make the second force-bearing member 16 and the first force-bearing member 9 bear force, and the metal corrugated plate to be repaired is stretched. After being stretched to a certain length, after being left for a certain period of time, the deformed rectangular section returns to the rectangular shape, thus completing the repair of the deformed metal corrugated plate.
