Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for processing fish scale mesh for electrolytic water hydrogen production. Background Technology
[0002] Cold stamping dies are deformation processing equipment used in cold stamping to shape materials into parts. Fish scale mesh is a widely used support mesh structure in the inner chamber of an electrolytic water electrolysis cell for hydrogen production. Before use in the electrolytic cell, the edges of the fish scale mesh need to be pressed down and flattened. Current technology for stamping fish scale mesh requires placing the punched mesh on a base plate, such as... Figure 1 As shown, the top plate is then moved downwards using a punch press to flatten the edges of the fish scale mesh. However, in actual use, after the bottom and top plates are pressed together, the stress release at the rear end of the pressed part of the fish scale mesh after it is removed from the punch press can cause local deformation, resulting in some areas warping and exceeding the required dimensions. This can cause the diaphragm to rupture during the installation of the electrolytic cell.
[0003] This application is submitted in order to address the aforementioned issues. Utility Model Content
[0004] This utility model discloses a stamping die for processing fish scale mesh for electrolytic water hydrogen production, aiming to solve the problems of local deformation, low pass rate and damage to the diaphragm in existing fish scale mesh.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a stamping die, including a base plate 1 for support and a top plate 3 for pressing.

[0007] The top plate 3 has: a central pressing part located in the middle, a buffer pressing part located on the outer periphery of the central pressing part, and a flattening part located on the outermost periphery;
[0008] The intermediate support part and the intermediate pressing part form an intermediate pressing area 6, the buffer support part and the buffer pressing part form a welding surface forming area 5, and the flattening support part and the flattening part form a flattening forming area 2.
[0009] The lower surface of the buffer molding part has a stepped slope 4, and the upper surface of the buffer support part has a boss, so that the height of the welding surface forming area 5 gradually decreases.
[0010] Preferably, the stepped slope 4 has a step near the middle and a first slope near the outer periphery, and the last step and the flattened part are connected by the first slope.
[0011] Preferably, the protrusion corresponds to the last step and the first ramp of the stepped slope 4. More preferably, the number of steps is 2 to 5. Steps can also be called stairs.

[0017] This application has the following beneficial effects:
[0018] 1. The stamping die of this application can effectively reduce the stress in the fish scale mesh during the stamping process of the top and bottom plates by utilizing the cooperation between the stepped inclined surface and the boss of the bottom plate.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to identify selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without making new inventive effort are within the scope of protection of this application.
[0026] A stamping die includes a base plate 1 for support and a top plate 3 for pressing. The base plate 1 has: a central support portion located in the middle, a buffer support portion located on the outer periphery of the central support portion, and a flattening support portion located on the outermost periphery.
[0027] The top plate 3 has: a central pressing part located in the middle, a buffer pressing part located on the outer periphery of the central pressing part, and a flattening part located on the outermost periphery;
[0028] The intermediate support portion and the intermediate molding portion form an intermediate molding area 6, which is used to mold the middle of the fish scale mesh 0. The buffer support portion and the buffer molding portion form a welding surface forming area 5, which is used to mold the welding surface area on the outer periphery of the fish scale mesh 0. The flattening support portion and the flattening portion form a flattening forming area 2, which is used to flatten the outermost periphery of the fish scale mesh 0.
[0029] The lower surface of the buffer molding part has a stepped slope 4, and the upper surface of the buffer support part has a boss, so that the height of the welding surface forming area 5 gradually decreases.
[0030] Preferably, the stepped slope 4 has a step near the middle and a first slope near the outer periphery, and the last step and the flattened part are connected by the slope.
[0031] Preferably, the boss corresponds to the last step and slope of the stepped ramp 4. More preferably, the distance between the boss and the slope is substantially equivalent to the height of the flattening forming area 2.
[0032] Preferably, the stepped slope 4 and the main body of the top plate 3 are detachably connected.
[0033] Preferably, the base plate 1 is a flat plate structure with the boss.
[0034] Preferably, the top plate 3 is a plate-like structure with its outer periphery protruding downwards.
[0035] Reference Figure 2-3 A stamping die for processing fish-scale mesh for hydrogen production via water electrolysis includes a base plate 1 for support and a top plate 3 for pressing. The base plate 1 has a boss, and the top plate 3 has a stepped slope 4 near its outer periphery. The spacing of the fish-scale mesh forming areas 6 is equal to or less than the height of the fish-scale mesh 0, allowing for adjustment of the mesh height. The height of the welding surface forming area 5 is the required forming dimension of the fish-scale mesh welding area. The height of the flattening forming area 2 is equal to the thickness of the fish-scale mesh 0, ensuring that the outermost periphery of the fish-scale mesh 0 is completely flattened.
[0036] Figure 1 This is a cross-sectional view of the stamping die structure for a conventional fish-scale mesh. The lower surface of the conventional top plate 3 and the buffer die part is a slope 7. The upper surface of the conventional bottom plate 1 and the buffer support part has a triangular cross-section for its boss. The apex of the boss corresponds to the front end of the slope 7.
[0037] In this application, the upper surface of the buffer support of the top plate 3 is a stepped slope 4. The boss of the bottom plate 1 is smaller in height and closer to the outer periphery. In addition, the stepped slope 4 is a detachable structure. When it is necessary to adjust the welding edge form and size of the fish scale mesh, the corresponding structure can be directly replaced, which greatly reduces the production cost.
[0038] In summary, to address the issue of localized warping after stamping of the fish-scale mesh, the specific operation of this application is as follows: the existing slope 7 in the top plate 3 is replaced with a stepped slope, and the height, position, and shape of the boss in the bottom plate 1 are varied to conform to the stepped slope of the top plate 3. Since the fish-scale mesh relies on the top plate 3 to constrain the shape of the welded ends, changing the slope shape and the bottom plate boss together improves the product qualification rate. Furthermore, by designing the stepped slope 4 as a detachable structure, the variability of the mold is greatly increased, reducing the high costs associated with production due to different technical requirements.
[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
