Description

Technical Field

[0001] This application relates to the field of powder metallurgy technology, and in particular to auxiliary powder distribution tools. Background Technology

[0002] Powder metallurgy forming is the core process in the production of carbon-carbon (C / C) composite panel boxes. This process requires first spreading loose carbon powder in a specific mold (such as a cubic mold). The uniformity and flatness of the powder filling in the mold are key factors affecting the quality of the blank.

[0003] Currently, the industry lacks specialized tools for assisting powder application, and scrapers are still widely used as auxiliary tools in the filler filling process. However, during storage or filling, carbon powder is prone to agglomeration due to factors such as electrostatic adsorption, uneven particle size distribution, and environmental humidity. Traditional auxiliary tools cannot address this issue, resulting in uneven powder layers, particle agglomeration, and surface pits. Furthermore, voids or agglomerates may exist within the powder layer, ultimately leading to poor quality of the subsequently produced green body. Utility Model Content

[0004] Therefore, it is necessary to provide an auxiliary powder distribution tool for assisting in the powder distribution of carbon-carbon fillers. Using this auxiliary powder distribution tool can effectively solve the agglomeration problem of carbon-carbon fillers and obtain a carbon-carbon filler powder layer with a smooth surface.

[0005] An auxiliary powder application tool includes a main body, the main body having a gripping component, a pushing end, and an abutting component. The pushing end extends along a first direction, the gripping component is connected to the pushing end, and the gripping component is used to push the pushing end to move along a second direction. The abutting component is located at both ends of the pushing end extending along the pushing end, and the abutting component is used to abut against the edge of a mold to support the auxiliary powder application tool.

[0006] The pusher end includes a first end face and a second end face opposite to each other. The first end face has a first nail tooth structure. The first nail tooth structure includes a plurality of first nail teeth distributed along a first direction. The first nail tooth structure is used to penetrate and loosen the filler.

[0007] The second end face has a protruding pusher extending in a first direction, the pusher having a pusher plane for flattening the filler.

[0008] In some embodiments, the pusher is in the shape of a triangular prism.

[0009] In some embodiments, the height of the pusher is 10mm to 40mm.

[0010] In some embodiments, the gripping component includes a gripping rod, a first support rod, and a second support rod. The gripping rod is connected to the pushing end, and the two ends of the first support rod are respectively connected to the pushing end and the gripping rod; the two ends of the second support rod are respectively connected to the pushing end and the gripping rod.

[0011] In some embodiments, the surface of the first end face also has a second nail tooth structure, the second nail tooth structure including a plurality of second nail teeth distributed along a first direction, the second nail teeth being staggered from the first nail teeth in a second direction.

[0012] In some embodiments, the maximum diameter of the second tooth is 6mm to 14mm; and / or

[0013] The height of the second tooth is 40mm~80mm; and / or

[0014] Each of the second nail teeth is evenly distributed along the first direction, and the distance between two adjacent second nail teeth is 80mm~120mm.

[0015] In some embodiments, the height of the first tooth is 40mm to 80mm; and / or

[0016] The distance between the projections of the first and second nail teeth in the first direction is 40mm to 60mm.

[0017] In some embodiments, the maximum diameter of the first tooth is 6mm to 14mm; and / or

[0018] Each of the first nail teeth is evenly distributed along the first direction, and the distance between two adjacent first nail teeth is 80mm~120mm.

[0019] In some embodiments, the length of the pusher end extending along the first direction is 100cm to 180cm.

[0020] In some embodiments, the abutting component is integrally formed with the pusher end.

[0021] The auxiliary powder distribution tool of this application forms contact with the mold edge frame by setting abutting components at both ends of the extending direction of the pushing end, thereby supporting the auxiliary powder distribution tool on the mold. Based on this, the pushing end is pushed back and forth in a specific direction by the holding components, achieving high-quality filling and leveling of carbon-carbon filler. The pushing end includes a first end face and a second end face. The surface of the first end face has a first tooth structure, which can penetrate and loosen the filler. Keeping the first end face on the lower side and moving the auxiliary powder distribution tool back and forth effectively breaks up the clumps generated by the carbon-carbon filler due to its own static electricity, helping to evenly disperse the powder. After the filler is loosened and clump-free, keeping the second end face on the lower side and moving the auxiliary powder distribution tool back and forth, the second end face has a protruding pushing plane, which can be used to level the filler. Using the above-mentioned auxiliary powder distribution tool in the carbon-carbon filler filling process can effectively reduce the occurrence of problems such as uneven surface and clumps after powder layer filling.

[0039] In the field of lithium-ion battery anode hot zone, carbon-carbon (C / C) composite material panels are gaining increasing market share due to their superior high-temperature resistance, mechanical strength, and longer service life compared to traditional graphite panels. Powder metallurgy forming is the core process in the production of carbon-carbon (C / C) composite material panels. This process requires spreading loose carbon powder in a specific mold (such as a cubic mold). The uniformity and flatness of the powder filling in the mold are key factors affecting the quality of the blank.

[0040] Currently, the industry lacks specialized tools for assisting powder application, and scrapers are still widely used as auxiliary tools in the filler filling process. However, during storage or filling, carbon powder is prone to agglomeration due to factors such as electrostatic adsorption, uneven particle size distribution, and environmental humidity. Traditional auxiliary tools cannot address this issue, resulting in uneven powder layers, particle agglomeration, and surface pits. Furthermore, voids or agglomerates may exist within the powder layer, ultimately leading to poor quality of the subsequently produced green body.

[0041] Based on this, this application provides an auxiliary powder distribution tool for assisting in the powder distribution of carbon-carbon fillers. Using this auxiliary powder distribution tool can effectively solve the agglomeration problem of carbon-carbon fillers and obtain a carbon-carbon filler powder layer with a smooth surface.

[0042] To more clearly illustrate the structure of the auxiliary powder application tool, the following description, in conjunction with the accompanying drawings, will explain its structure. For examples, please refer to the attached drawings. Figures 1-5 ,in, Figure 1 This is a schematic diagram of the auxiliary powder application tool according to one embodiment of this application. Figure 2 This is a front view of the auxiliary powder application tool according to one embodiment of this application. Figure 3 This is a view of the auxiliary powder application tool corresponding to the first end face 100 in one embodiment of this application. Figure 4 This is a side view of the auxiliary powder application tool according to one embodiment of this application. Figure 5 This is a view of the second end face 200 of the auxiliary powder application tool according to one embodiment of this application. In the figure, x represents the first direction and y represents the second direction.

[0043] Please see Figure 1 As shown, the main body of the auxiliary powder application tool has a gripping component, a pushing end, and an abutting component 300. The pushing end extends along a first direction, and the gripping component is connected to the pushing end, used to push the pushing end to move along a second direction. The abutting component 300 is located at both ends along the extending direction of the pushing end, used to abut against the edge frame of the mold, thereby supporting the auxiliary powder application tool on the mold and maintaining its position. Understandably, the first direction intersects with the second direction. Furthermore, the first direction is perpendicular to the second direction.

[0044] The pusher end includes a first end face 100 and a second end face 200, see [reference]. Figure 2 , 3 As shown, the first end face 100 has a first nail tooth 110 structure, which includes a plurality of first nail teeth 110 distributed along a first direction. The first nail tooth 110 structure is used to penetrate and loosen the filler.

[0045] See Figure 2 , 5As shown, the second end face 200 has a protruding pusher 210 that extends along a first direction and has a pusher plane for flattening the filler. Understandably, the pusher 210 has a consistent height along the direction in which it extends, thereby forming a pusher plane for flattening the filler.

[0046] The aforementioned auxiliary powder distribution tool uses a gripping component to push the feeding end back and forth in a specific direction, achieving high-quality filling and leveling of carbon-carbon filler. The feeding end includes a first end face 100 and a second end face 200. The surface of the first end face 100 has a first toothed structure 110, which can penetrate and loosen the filler. Maintaining the first end face 100 on the lower side and moving the auxiliary powder distribution tool back and forth effectively breaks up clumps generated by the carbon-carbon filler due to its own static electricity, helping to evenly disperse the powder. After loosening the filler and eliminating clumps, maintaining the second end face 200 on the lower side and moving the auxiliary powder distribution tool back and forth allows it to level the filler due to the protruding feeding plane on its surface. Using this auxiliary powder distribution tool in the carbon-carbon filler filling process effectively reduces problems such as uneven surface and clumps after powder layer filling.

[0047] Please see Figure 4 As shown, in some embodiments, the pusher 210 is shaped as a triangular prism. Understandably, one face of the triangular prism is in contact with the second end face 200, and the top of the triangular prism is further away from the second end face 200 than this face and is used to flatten the filler.

[0048] In some embodiments, the height of the pusher 210 is 10mm to 40mm. Optionally, the height of the pusher 210 can be, but is not limited to, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm or other values ​​within the range of 10mm to 40mm.

[0049] Please see Figure 3 As shown, in some embodiments, the gripping component includes a gripping rod 410, a first support rod 420, and a second support rod 430. The gripping rod 410 is connected to the pushing end, the two ends of the first support rod 420 are connected to both the pushing end and the gripping rod 410, and the two ends of the second support rod 430 are connected to both the pushing end and the gripping rod 410. This design allows the gripping rod 410, the first support rod 420, and the second support rod 430 to form a triangular support structure, resulting in more even force distribution and more stable operation of the auxiliary powder-distributing tool during material pushing.

[0050] In some embodiments, the surface of the first end face 100 also has a second nail tooth 120 structure, the second nail tooth 120 structure including a plurality of second nail teeth 120 distributed along a first direction, the second nail teeth 120 and the first nail teeth 110 not overlapping in a second direction.

[0054] In some embodiments, the height of the second nail tooth 120 is 40mm to 80mm. Optionally, the height of the second nail tooth 120 can be, but is not limited to, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 80mm or other values ​​within the range of 40mm to 80mm.

[0055] In some embodiments, the second nail tooth 120 may also be a cylinder, a cone, or a cylinder structure with a cone at the top. Further, the second nail tooth 120 may be a cylinder, a cone, or a cylinder with a cone at the top.

Furthermore, the distance between the projections of the first nail tooth 110 and the second nail tooth 120 in the second direction is not limited in this application and can be adjusted according to the structural dimensions of the pusher end.

[0059] In some embodiments, each of the first nail teeth 110 is uniformly distributed along a first direction, and the distance between two adjacent first nail teeth 110 is 80mm to 120mm. Optionally, the distance between two adjacent first nail teeth 110 can be, but is not limited to, 80mm, 90mm, 100mm, 110mm, 120mm or other values ​​within the range of 80mm to 120mm.
