Description

Technical Field

[0001] This utility model relates to the field of graphite electrode processing technology, specifically to a tooling for impregnating, cleaning, and drying flexible graphite electrodes. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Currently, flexible graphite electrodes require impregnation, cleaning, and drying processes during processing. During these processes, the flexible graphite electrodes need to be placed in a fixture to prevent warping and deformation. Traditional fixtures consist of four side frames connected sequentially to form a cuboid space. Multiple sets of columns are located within this cuboid space, distributed along its length. Each set includes multiple columns evenly spaced along the width of the cuboid space. The tops of the columns connect to horizontal columns distributed along the length of the cuboid space. The bottoms of the columns in the same set connect to a horizontal beam. The two ends of the horizontal beam are welded and fixed to two opposing side frames parallel to the length of the cuboid space. The columns pass through through holes in the horizontal beam, and the two ends of the horizontal columns pass through the two side frames parallel to the width of the cuboid space. In use, the flexible graphite electrode is placed between two adjacent columns, with the bottom of the flexible graphite electrode supported on the horizontal beam. The horizontal columns correspond to the top edges of the flexible graphite electrode. The above fixture has the following drawbacks: 1. When in use, the top edge of the flexible graphite electrode is located between two adjacent transverse columns, making it inconvenient to remove the flexible graphite electrode.

[0004] 2. The bottom of the column needs to be inserted into the corresponding through hole of the horizontal beam. Multiple through holes corresponding to the column need to be machined on the horizontal beam. Each through hole must correspond to the corresponding column. The machining of the through holes is difficult. The horizontal beam is welded and fixed to the side frame. It is impossible to ensure that the support surfaces of the multiple horizontal beams for the flexible graphite electrode are on the same plane. Therefore, the welding and positioning of the horizontal beam is difficult. As a result, the current tooling is difficult to process, manufacture and assemble. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for impregnating, cleaning and drying flexible graphite plates, which reduces the difficulty of processing and assembly and facilitates the removal of flexible graphite plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a tooling for impregnating, cleaning, and drying flexible graphite electrode plates, including two first side frames and two second side frames arranged opposite to each other. Multiple sets of columns are arranged within the accommodating space formed by the first and second side frames. These columns are distributed along a direction parallel to the first side frames, and multiple columns from the same set are distributed along a direction parallel to the second side frames. The top of each column is fixed to an upper horizontal column, the end of the upper horizontal column passes through a top through-hole in the second side frame, the bottom of the column is connected to a lower horizontal column, and the end of the lower horizontal column passes through a bottom through-hole in the second side frame. A perforated support plate is provided between the bottoms of the first and second side frames, located below the lower horizontal column.

[0007] Optionally, the hollow support plate includes a plate body with multiple elongated holes arranged in an array on the plate body, the long axis of the elongated holes being parallel to the first side frame.

[0008] Optionally, the hollow support plate has a first protrusion on both sides, and the first protrusion is embedded in the first positioning hole at the bottom of the first side frame.

[0009] Optionally, the upper transverse column is provided with multiple concave sections, which are recessed inward toward the direction of the hollow support plate.

[0010] Optionally, both ends of the second side frame are provided with a plurality of second protrusions, and correspondingly, both ends of the first side frame are provided with second positioning holes corresponding to the second protrusions, and the second protrusions are embedded in the corresponding second positioning holes.

[0011] Optionally, multiple sets of columns are distributed at equal intervals along a direction parallel to the first side frame.

[0012] Optionally, multiple columns in the same group are distributed at equal intervals along a direction parallel to the second side frame.

[0013] Optionally, multiple connecting plates are provided between the top ends of the two first side frames, and the ends of the connecting plates are detachably connected to the top ends of the first side frames.

[0014] Optionally, the top of the first side frame is provided with a flange extending outward, and the end of the connecting plate is bent to form a hook, which is hooked to the outer edge of the flange.

[0015] Optionally, the uprights, upper horizontal columns, and lower horizontal columns are all made of steel pipes.

[0016] The beneficial effects of this utility model are as follows: 1. In the tooling of this utility model, among multiple sets of columns, the bottom end of the corresponding column is connected to the lower horizontal column. The end of the lower horizontal column passes through the bottom through hole of the second side frame. The bottom of the column is fixed by the lower horizontal column and the bottom through hole. Therefore, it is only necessary to process the bottom through hole corresponding to the number of columns in the same set at the bottom of the second side frame. Compared with the traditional method of processing through holes corresponding to the number of columns in the same set for each beam, this greatly reduces the amount of through hole processing and reduces the processing difficulty. At the same time, the flexible graphite electrode plate is supported by the hollow support plate. The hollow support plate can ensure the flatness of the support surface, reduce the positioning difficulty during welding, and reduce the assembly difficulty.

[0017] 2. The tooling of this utility model has a concave section on the upper transverse column, which can expose the top edge of the flexible graphite electrode plate, making it convenient to remove the flexible graphite electrode plate from the tooling. Attached Figure Description

[0020] Example 1 This embodiment provides a tooling for impregnating, cleaning, and drying flexible graphite electrode plates, such as... Figures 1-4 As shown, it includes two opposing first side frames 1 and two opposing second side frames 2. The first side frames 1 and the second side frames 2 are connected in sequence to enclose a cuboid-shaped receiving space. The receiving space is used to place flexible graphite plates. The length of the first side frame 1 is greater than the length of the second side frame 2. The first side frame 1 is arranged along the length direction of the receiving space, and the second side frame 2 is arranged along the width direction of the receiving space. In this embodiment, the direction parallel to the first side frame 1 is defined as the first direction, and the direction parallel to the second side frame 2 is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0021] Both the first side frame 1 and the second side frame 2 are made of rectangular plates, and holes are made in the rectangular plates to form the first side frame 1 and the second side frame 2.

[0022] The accommodating space is provided with multiple sets of columns 3, which are distributed at equal intervals along the first direction. Preferably, eight sets of columns 3 are provided. It is understood that those skilled in the art can set the number of sets of columns 3 according to actual needs, which will not be described in detail here.

[0023] Each group of columns 3 includes multiple columns 3 evenly spaced along the second direction. The number of columns 3 in each group can be set according to actual needs, and will not be described in detail here.

[0024] Among the multiple sets of columns 3, the corresponding columns are defined as columns 3 whose axes are located on the same plane parallel to the first side frame 1. The top of the corresponding columns 3 is connected to the same upper horizontal column 4, and the bottom is connected to the same lower horizontal column 5. The columns 3, the upper horizontal column 4, and the lower horizontal column 5 are all set perpendicularly and welded to each other.

[0025] One end of the upper horizontal column 4 passes through the corresponding top through hole of the second side frame 2 on one side and is welded and fixed to the second side frame 2, and the other end passes through the corresponding top through hole of the second side frame 2 on the other side and is welded and fixed to the second side frame 2.

[0026] One end of the lower horizontal column 5 passes through the corresponding bottom through hole of the second side frame 2 on one side and is welded and fixed to the second side frame 2. The other end passes through the corresponding bottom through hole of the second side frame 2 on the other side and is welded and fixed to the second side frame 2.

[0027] In the same group of multiple columns 3, two adjacent columns 3 form a space for accommodating flexible graphite plates.

[0028] In this embodiment, the upright column 3, the upper horizontal column 4, and the lower horizontal column 5 are all made of steel pipes, which are easy to obtain and have low cost.

[0029] A hollow support plate 6 is provided between the bottom ends of the first side frame 1 and the second side frame 2. The hollow support plate 6 is located below multiple lower horizontal columns 5. In this embodiment, the hollow support plate 6 adopts a rectangular plate body that matches the accommodating space. Multiple elongated holes 7 are opened on the plate body in an array to form a hollow structure.

[0030] The long axis of the elongated hole 7 is distributed along the first direction.

[0031] The upper surface of the perforated support plate serves as a support surface, which contacts the bottom edge of the flexible graphite electrode to support the flexible graphite electrode.

[0032] In this embodiment, a hollow support plate 6 is used to support multiple flexible graphite plates. The hollow support plate 6 can ensure the flatness of the support surface. Compared with the traditional scheme of using multiple transverse beams to support flexible graphite plates, it reduces the positioning difficulty when welding the hollow support plate 6 to the side frame and reduces the assembly difficulty.

[0033] Furthermore, in order to make the supporting surface of the hollow support plate 6 perpendicular to the column 3, the hollow support plate 6 is provided with a plurality of first protrusions 8 on both sides of its parallel first direction. Preferably, the plurality of first protrusions 8 are distributed along the first direction and are evenly spaced along the edge of the hollow support plate 6.

[0034] In this embodiment, the first protrusion 8 is a cuboid protrusion.

[0035] Correspondingly, the bottom of the first side frame 1 is provided with a plurality of first positioning holes that match the first protrusion 8. Since the first protrusion 8 is a cuboid protrusion, the first positioning hole is a rectangular hole that matches the first protrusion 8. When the hollow support plate 6 is fixed to the first side frame 1, the first protrusion 8 is embedded in the first positioning hole. Then the first side frame 1 is welded and fixed to the hollow support plate 6. Through the cooperation of the first positioning hole and the first protrusion 8, the hollow support plate 6 and the column 3 are ensured to be perpendicular to each other. There is no need for manual positioning of the hollow support plate 6, which reduces the assembly difficulty.

[0036] Furthermore, in order to facilitate the assembly between the first side frame 1 and the second side frame 2, a plurality of second protrusions 9 are provided on both end edges of the second side frame 2. Preferably, the second protrusions 9 are cuboid protrusions. Correspondingly, the end of the first side frame 1 is provided with a second positioning hole that matches the second protrusions 9. The second positioning hole is a rectangular hole that matches the cuboid protrusion.

[0037] When assembling the first side frame 1 and the second side frame 2, the second protrusion 9 is embedded in the corresponding second positioning hole, and then the first side frame 1 and the second side frame 2 are welded and fixed. There is no need for manual welding and positioning of the first side frame 1 and the second side frame 2, which reduces the assembly difficulty.

[0038] In this embodiment, to facilitate the removal of the flexible graphite electrode from the fixture, all the upper transverse columns 4 are provided with multiple concave sections 10. The positions of the concave sections 10 on all the upper transverse columns 4 are corresponding, and the concave sections 10 are arc-shaped sections that are concave inward toward the hollow support plate 6. Through the concave sections 10, the top part of the flexible graphite electrode can be exposed. This part serves as a gripping part, which allows the flexible graphite electrode to be easily removed from the fixture.

[0039] Preferably, the upper transverse column has two concave sections 10, which are symmetrically distributed with respect to the center of the upper transverse column 4.

[0040] The bottoms of the two first side frames 1 are connected by a hollow support plate 6. In order to prevent the tops of the two first side frames from bending and deforming, a plurality of connecting plates 11 are provided between the tops of the two first side frames 1. One end of the connecting plate 11 is detachably connected to the top of one side first side frame 1, and the other end is detachably connected to the top of the other side first side frame 1.

[0041] In this embodiment, two connecting plates 11 are provided. It is understood that those skilled in the art can set the number of connecting plates according to actual needs.

[0042] The connection method between the connecting plate 11 and the top of the first side frame 1 is as follows: The top of the first side frame 1 is provided with a 90° flange 12 extending outward. The end of the connecting plate 11 is bent to form a hook 13. The hook 13 at the end of the connecting plate 11 is hooked and connected to the outer edge of the flange 12, thereby realizing the detachable connection between the connecting plate 11 and the top of the first side frame 1.

[0043] It is understood that those skilled in the art can set the detachable connection method between the connecting plate 11 and the top of the first side frame 1 according to actual needs, which will not be described in detail here.

[0044] The tooling in this embodiment, such as Figure 5 As shown, in use, the flexible graphite electrode plate 14 is vertically positioned and placed in the space between two adjacent columns 3 in the same group. The bottom of the flexible graphite electrode plate 14 cooperates with the support surface of the hollow support plate 6, and is supported by the hollow support plate 6. The multiple columns 3 can limit the position of the flexible graphite electrode plate 14 to prevent it from warping. Since the first side frame 1, the second side frame 2 and the hollow support plate 6 are all hollowed out, the tooling can be placed into the impregnation equipment along with the flexible graphite electrode plate 14 to impregnate the flexible graphite electrode plate 14. After being placed into the cleaning equipment, the flexible graphite electrode plate 14 can be cleaned. After being placed into the drying equipment, the flexible graphite electrode plate 14 can be dried.

[0045] In this embodiment, the tooling uses the lower horizontal column 5 and the bottom through hole to fix the bottom of the column. Therefore, it is only necessary to process the bottom through hole corresponding to the number of columns 3 in the same group at the bottom of the second side frame 2. Compared with the traditional method of processing through holes corresponding to the number of columns in the same group for each beam, this greatly reduces the amount of through hole processing and reduces the processing difficulty. At the same time, the flexible graphite electrode plate is supported by the hollow support plate 6. The hollow support plate 6 can ensure the flatness of the support surface, reduce the positioning difficulty during welding, and reduce the assembly difficulty.

[0046] The tooling manufacturing method in this embodiment is as follows: The first side frame 1, the second side frame 2, and the hollow support plate 6 are pre-processed and manufactured. The upright column 3, the upper horizontal column 4, and the lower horizontal column 5 are then manufactured and welded to the corresponding upper horizontal column 4 and lower horizontal column 5.

[0047] One end of the upper horizontal column 4 and the lower horizontal column 5 are respectively passed through the top and bottom through holes of the second side frame 2 on one side. Then the other ends of the upper horizontal column 4 and the lower horizontal column 5 are connected to the second side frame 2 on the other side. The other ends of the upper horizontal column 4 and the lower horizontal column 5 are respectively passed through the top and bottom through holes of the second side frame 2 on the other side.

[0048] Place the hollow support plate 6 between the bottom of the two second side frames 2, with the hollow support plate 6 located below the lower horizontal column 5.

[0049] Then, the first side frame 1 is assembled on both sides of the second side frame 2 and the hollow support plate 6, with the first protrusion 8 embedded in the first positioning hole and the second protrusion 9 embedded in the second positioning hole.

[0050] After assembly, the first side frame 1 and the second side frame 2 are welded and fixed, and the upper horizontal column 4 and the lower horizontal column 5 are welded and fixed to the second side frame 2.

[0051] Then, install the connecting plate 11 between the tops of the two first side frames 1. When it is necessary to place the flexible graphite electrode 14, the connecting plate 11 can be removed. After the flexible graphite electrode 14 is placed, the connecting plate 11 is installed again.

[0052] The tooling in this embodiment is easy and quick to manufacture and assemble, and the processing difficulty is low.

[0053] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
