Description
Technical Field
[0001] This utility model belongs to the field of stamping die technology, specifically relating to a graphite plate deburring tool. Background Technology
[0002] After the graphite plate is stamped, it has multiple through holes inside. The inner circle of the through holes has burrs, and the outer perimeter of the graphite plate also has burrs. Therefore, in order to make the graphite plate meet the manufacturing requirements, it is necessary to perform deburring treatment.
[0003] Traditional deburring methods typically employ two approaches. The first, commonly used method, is manual grinding. Workers use hand-held grinding tools to sequentially grind the external and internal through-holes of the graphite plate. This method is time-consuming, labor-intensive, and inefficient. Furthermore, the uneven surface roughness and smoothness result from variations in operating force and speed during manual grinding. This method is suitable for small-batch production and simple flat or edge treatments. The second, commonly used method is vibratory grinding or drum grinding. Graphite plates and soft abrasives are placed in a vibrating device, and burrs are removed through friction. However, if too many graphite plates are placed at once, vibration and collision between the plates can cause uneven burr removal. Moreover, the time required for deburring through vibration friction is also long, making it unsuitable for rapid, large-scale production.
[0004] How to design a deburring device that can remove burrs from the punched parts and outer ring of the processed graphite plate, and achieve all-round deburring in a single stamping, is a technical problem that urgently needs to be solved. Utility Model Content
[0005] This utility model provides a deburring fixture for graphite plates to solve the problem of overall burr removal from the punched parts and outer ring parts of the processed graphite plates.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A graphite plate deburring fixture includes a worktable; the worktable includes a lower die base and an upper die base disposed above the lower die base;
[0008] The lower mold base is provided with a mounting position for installing a graphite plate;
[0009] The upper die base includes a fixed plate, a drive mechanism, and a stamping mechanism; the fixed plate is connected above the worktable, the drive mechanism is connected below the fixed plate, and the stamping mechanism includes a stamping base and a punch. The stamping base is connected to the drive mechanism, and the punch is connected to the side of the stamping base facing the lower die base. The punch has an inner stamping ring assembly near the center of the punch and an outer stamping ring assembly disposed on the outer periphery of the inner stamping ring assembly.
[0010] The driving mechanism drives the stamping mechanism to press the graphite plate downwards, so that the outer ring stamping assembly of the punch can press the outer ring of the graphite plate to remove the burrs on the outer ring of the graphite plate, and the inner ring stamping assembly can press the through hole of the graphite plate to remove the burrs on the through hole.
[0011] The stamping outer ring assembly includes a first outer ring punch, a second outer ring punch, a third outer ring punch, and a fourth outer ring punch; the first outer ring punch and the second outer ring punch are symmetrically arranged along the width direction of the stamping base, and the third outer ring punch and the fourth outer ring punch are symmetrically arranged along the length direction of the stamping base.
[0012] The bottom circumference of the first outer ring punch forms an inwardly inclined first guide slope; the bottom circumference of the second outer ring punch forms an inwardly inclined second guide slope; the bottom circumference of the third outer ring punch forms an inwardly inclined third guide slope; and the bottom circumference of the fourth outer ring punch forms an inwardly inclined fourth guide slope.
[0013] The stamped inner ring assembly includes a first inner ring punch, a second inner ring punch, a third inner ring punch, a fourth inner ring punch, a fifth inner ring punch, and a sixth inner ring punch; the first inner ring punch, the second inner ring punch, and the third inner ring punch are arranged in a row along the width direction of the stamping base inside the third outer ring punch; the fourth inner ring punch, the fifth inner ring punch, and the sixth inner ring punch are arranged in a row along the width direction of the stamping base inside the fourth inner ring punch.
[0014] The bottom circumference of the first inner ring punch forms an inwardly inclined fifth guide slope; the bottom circumference of the second inner ring punch forms an inwardly inclined sixth guide slope; the bottom circumference of the third inner ring punch forms an inwardly inclined seventh guide slope; the bottom circumference of the fourth inner ring punch forms an inwardly inclined eighth guide slope; the bottom circumference of the fifth inner ring punch forms an inwardly inclined ninth guide slope; and the bottom circumference of the sixth inner ring punch forms an inwardly inclined tenth guide slope.
[0015] The upper mold base also includes support columns and an upper template; the fixed plate is connected to the support columns around its perimeter, and the fixed plate is connected to the top of the workbench through the support columns; the upper template is connected to the bottom of the fixed plate.
[0016] The lower mold base includes support legs and a lower template; the lower template is connected to the support legs around its perimeter and is connected to the workbench above the workbench via the support legs; the height of the lower template from the workbench is less than the height of the support legs from the workbench, so that a height difference is formed between the lower template and the support legs to form an installation position for installing graphite plates within the lower template.
[0017] The lower template has punches corresponding to the through holes of the graphite plate, and the inner punching ring assembly can punch the holes to remove the burrs from the through holes of the graphite plate.
[0018] The support leg has a mounting hole extending along the height of the support leg, with one end of the mounting hole penetrating the side of the support leg facing the upper mold base; the bottom wall of the mounting hole is connected to an elastic element.
[0019] The stamping mechanism also includes connecting rods; the connecting rods are connected to the four corners of the stamping base and are set corresponding to the mounting holes; the connecting rods can extend into the mounting holes when the stamping mechanism presses downward.
[0020] An avoidance groove is provided on the side where the support leg connects to the lower template to prevent interference when the stamping mechanism presses downward; the avoidance groove has an inner arc surface.
[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0022] 1. This application relates to a graphite plate deburring fixture, including a worktable; the worktable includes a lower die base and an upper die base disposed above the lower die base; the lower die base has a mounting position for mounting the graphite plate; the upper die base includes a fixed plate, a driving mechanism, and a stamping mechanism; the fixed plate is connected above the worktable, the driving mechanism is connected below the fixed plate, and the stamping mechanism includes a stamping base and a punch; the stamping base is connected to the driving mechanism, and the punch is connected to the side of the stamping base facing the lower die base; the punch has a stamping inner ring assembly near the center of the punch and a stamping outer ring assembly disposed around the outer periphery of the stamping inner ring assembly; the driving mechanism drives the stamping mechanism to stamp the graphite plate downwards, so that the stamping outer ring assembly of the punch can stamp the outer ring of the graphite plate to remove burrs from the outer ring of the graphite plate, and the stamping inner ring assembly can stamp the through holes of the graphite plate to remove burrs from the through holes.
[0023] This application enables the overall deburring of the punched and outer ring areas of processed graphite plates. All burrs can be removed in a single stamping operation, achieving not only comprehensive deburring but also batch deburring. It eliminates the need for manual hand-held grinding tools; workers simply hold the graphite plate or a robot transports it to the mounting position in the lower die base. The stamping mechanism of the upper die base then performs a single downward stamping motion to remove the burrs from both the inner and outer rings of the graphite plate. After one graphite plate is deburred, the process proceeds to the next. The average deburring time for each graphite plate is reduced to approximately 10 seconds, thus achieving high efficiency in deburring. This allows for the simultaneous deburring of large batches of graphite plates, improving the final product quality.
[0024] 2. In a preferred embodiment of the present invention, the stamping outer ring assembly includes a first outer ring punch, a second outer ring punch, a third outer ring punch, and a fourth outer ring punch; the first outer ring punch and the second outer ring punch are symmetrically arranged along the width direction of the stamping base, and the third outer ring punch and the fourth outer ring punch are symmetrically arranged along the length direction of the stamping base.
[0025] The first outer ring punch of the stamping outer ring assembly is located at the front end, the second outer ring punch is located at the rear end, the third outer ring punch is located at the left end, and the fourth outer ring punch is located at the right end. The first and second outer ring punches are symmetrically arranged front and rear, and the third and fourth outer ring punches are symmetrically arranged left and right, so that the first, second, third, and fourth outer ring punches together form an outer ring layer protruding from the bottom surface of the punch base. During the downward stamping process, the entire first, second, third, and fourth outer ring punches can surround and enclose the outer ring of the graphite plate to remove the burrs on the outer ring of the graphite plate.
[0026] 3. In a preferred embodiment of the present invention, the bottom periphery of the first outer ring punch forms an inwardly inclined first guide slope; the bottom periphery of the second outer ring punch forms an inwardly inclined second guide slope; the bottom periphery of the third outer ring punch forms an inwardly inclined third guide slope; and the bottom periphery of the fourth outer ring punch forms an inwardly inclined fourth guide slope.
[0027] The first outer ring punch adopts a cuboid structure. The four sides of the bottom of the first outer ring punch are respectively provided with inclined slopes. The four inclined slopes enclose the first guide slope at the bottom of the first outer ring punch. This design makes the bottom dimension of the first outer ring punch smaller than the top dimension. This not only helps to prevent the bottom of the first outer ring punch from interfering with the graphite plate when the first outer ring punch is pressed down, but also allows the burrs to be pressed down by the inclined first guide slope during the punch's downward pressing process due to the narrow bottom and wide top of the first outer ring punch. When the wider top of the graphite plate is pressed down, the burrs are cut or flattened. When the punch falls completely, the burrs on the side of the product can be completely removed.

[0044] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0045] This utility model relates to a deburring fixture for graphite plates, such as... Figure 1-3 As shown, it includes a worktable 1; the worktable 1 includes a lower mold base 2 and an upper mold base 3 disposed above the lower mold base 2;
[0046] The lower mold base 2 is provided with a mounting position for installing the graphite plate 16;
[0047] The upper die base 3 includes a fixed plate 31, a drive mechanism 32, and a stamping mechanism 33; the stamping mechanism 33 includes a stamping base 331 and a punch 332. The stamping base 331 is connected to the drive mechanism 32, and the punch 332 is connected to the side of the stamping base 331 facing the lower die base 2; the punch 332 has a stamping inner ring assembly 9 near the center of the punch 332, and a stamping outer ring assembly 4 disposed on the outer periphery of the stamping inner ring assembly 9;
[0048] The driving mechanism 32 drives the stamping mechanism 33 to press the graphite plate 16 downward, so that the outer ring stamping assembly 4 of the punch 332 can press the outer ring of the graphite plate 16 to remove the burrs on the outer ring of the graphite plate 16, and the inner ring stamping assembly 9 can press the through hole of the graphite plate 16 to remove the burrs on the through hole.
[0049] After the graphite plate 16 is stamped, it has multiple through holes formed by stamping. The inner ring of these through holes has burrs, and the outer perimeter of the graphite plate 16 also has burrs. Therefore, deburring is necessary to meet the manufacturing requirements of the graphite plate 16. Traditional deburring methods typically employ two approaches. The first, commonly used method, is manual grinding. Workers use hand-held grinding tools to grind the exterior and interior of the graphite plate 16 sequentially. This manual grinding method is inefficient, and variations in operating force and speed during manual grinding result in inconsistent surface roughness and flatness, easily leading to uneven grinding. Therefore, this method is suitable for small-batch production and simple flat or edge processing. The second commonly used method is vibratory grinding or drum grinding. This method typically involves placing the graphite plate 16 and soft abrasives (such as resin grinding blocks) into a vibrating device to remove burrs through friction. However, this method is also unsuitable for large-scale production. If too many graphite plates 16 are placed at once, vibration collisions between the plates can easily occur, also resulting in uneven grinding. Therefore, based on the above considerations, this application requires the design of a deburring device capable of removing burrs from the punched and outer ring areas of the processed graphite plate 16. All burrs can be removed in a single stamping operation, achieving not only comprehensive deburring but also batch deburring. No manual hand-held grinding tools are required; workers simply hold the graphite plate 16 or a robot transports it to the mounting position in the lower die base 2. The stamping mechanism 33 of the upper die base 3 then performs a single downward stamping to remove the burrs from the interior and outer ring of the graphite plate 16. After one graphite plate 16 is deburred, the next graphite plate 16 is deburred. The average deburring time for each graphite plate 16 is reduced to approximately 10 seconds, thus improving deburring efficiency and enabling the simultaneous deburring of large batches of graphite plates 16, thereby improving the final product quality of the graphite plates 16.
[0050] like Figure 1As shown, the worktable 1 has a cuboid structure with a square worktable 1 surface. The lower die base 2 and the upper die base 3 are connected to the upper part of the worktable 1. The upper die base 3 is located at a predetermined distance above the lower die base 2. The purpose is to allow the stamping mechanism 33 and the driving mechanism 32 in the upper die base 3 to move downwards to stamp the graphite plate 16 on the lower die base 2. In use, the fixing plate 31 in the upper mold base 3 of this application is fixed. The drive mechanism 32 connected below the fixing plate 31 can extend towards the lower mold base 2. The bottom of the drive mechanism 32 is connected to the stamping mechanism 33. The stamping mechanism 33 is driven to move downward by the drive mechanism 32. The stamping mechanism 33 includes a stamping base 331 and a punch 332. The stamping base 331 is connected to the drive mechanism 32. The punch 332 is connected to the side of the stamping base 331 facing the lower mold base 2. When the stamping mechanism 33 moves downward, it can drive the punch to move downward, thereby realizing that the punch 332 presses the graphite plate 16 downward.
[0051] The punch 332 includes an inner stamping ring assembly 9 near the center of the punch 332 and an outer stamping ring assembly 4 disposed on the outer periphery of the inner stamping ring assembly 9. The inner stamping ring assembly 9 is used to punch downward through the through hole of the graphite plate 16. The through hole of the graphite plate 16 is opened in the graphite plate 16. Therefore, by punching downward through the through hole of the graphite plate 16 by the inner stamping ring assembly 9, the burrs of the through hole of the graphite plate 16 can be removed. The outer stamping ring assembly 4 is used to punch downward on the outer periphery of the graphite plate 16. The punching mechanism 33 is driven by the driving mechanism 32 to punch downward on the graphite plate 16, so that the outer stamping ring assembly 4 of the punch 332 can punch the outer periphery of the graphite plate 16 to remove the burrs on the outer periphery of the graphite plate 16. Thus, through the special setting of the punch 332, the burrs on the inner ring of the through hole and the outer peripheral surface of the graphite plate 16 are fully removed, so that all the burrs of the graphite plate 16 can be removed in one punch, which improves the efficiency of deburring and saves manpower and material resources.
[0052] In a preferred embodiment, the stamping outer ring assembly 4 includes a first outer ring punch 41, a second outer ring punch 42, a third outer ring punch 43, and a fourth outer ring punch 44; the first outer ring punch 41 and the second outer ring punch 42 are symmetrically arranged along the width direction of the stamping base 331, and the third outer ring punch 43 and the fourth outer ring punch 44 are symmetrically arranged along the length direction of the stamping base 331.
[0053] like Figure 3As shown, the first outer ring punch 41 of the stamping outer ring assembly 4 is located at the front end, the second outer ring punch 42 is located at the rear end, the third outer ring punch 43 is located at the left end, and the fourth outer ring punch 44 is located at the right end. The first outer ring punch 41 and the second outer ring punch 42 are symmetrically arranged front and rear, and the third outer ring punch 43 and the fourth outer ring punch 44 are symmetrically arranged left and right, so that the first outer ring punch 41, the second outer ring punch 42, the third outer ring punch 43 and the fourth outer ring punch 44 surround and form an outer ring layer protruding on the bottom surface of the punch 332 base. During the downward stamping process of the punch 332, the entire first outer ring punch 41, the second outer ring punch 42, the third outer ring punch 43 and the fourth outer ring punch 44 can surround and contain the outer ring of the graphite plate 16 to remove the burrs on the outer ring of the graphite plate 16.
[0054] Furthermore, it is important to note during the design that the distance between the first outer ring punch 41 and the second outer ring punch 42 is equal to the width of the graphite plate 16. This ensures that when the punch 332 presses downward, the first outer ring punch 41 and the second outer ring punch 42 can precisely impact the outer edges of both sides of the graphite plate 16 in the width direction, i.e., the long edges of both sides of the graphite plate 16, thus removing the burrs in the outer ring.
[0055] Similarly, it is important to note during the design that the distance between the third outer ring punch 43 and the fourth outer ring punch 44 is equal to the length of the graphite plate 16. This ensures that when the punch 332 presses downward, the third outer ring punch 43 and the fourth outer ring punch 44 can just strike the outer edges on both sides of the graphite plate 16 along its length, i.e., the wide edges on both sides of the graphite plate 16, thus removing the burrs in the outer ring.
[0056] It should be noted that the spacing between the four legs 21 located at the corners of the lower template 22, as described below, should be sufficient to accommodate the first outer ring punch 41, the second outer ring punch 42, the third outer ring punch 43, and the fourth outer ring punch 44, in order to prevent interference between the first outer ring punch 41, the second outer ring punch 42, the third outer ring punch 43, and the fourth outer ring punch 44 and the legs 21 when they are punching downwards.
[0057] In a preferred embodiment, the bottom periphery of the first outer ring punch 41 forms an inwardly inclined first guide slope 5; the bottom periphery of the second outer ring punch 42 forms an inwardly inclined second guide slope 6; the bottom periphery of the third outer ring punch 43 forms an inwardly inclined third guide slope 7; and the bottom periphery of the fourth outer ring punch 44 forms an inwardly inclined fourth guide slope 8.
[0058] like Figure 3As shown, taking the first outer ring punch 41 as an example, the first outer ring punch 41 adopts a cuboid structure. The four sides of the bottom of the first outer ring punch 41 are respectively provided with inclined slopes. The four inclined slopes enclose the first guide slope 5 at the bottom of the first outer ring punch 41. This configuration makes the bottom size of the first outer ring punch 41 smaller than the top size of the first outer ring punch 41. This not only helps the first outer ring punch 41 to press down without interference or collision between the bottom end of the first outer ring punch 41 and the graphite plate 16, but also allows the first outer ring punch 41 to press down smoothly. Under the structural action of the first outer ring punch 41 with a narrow bottom and a wide top, during the pressing process of the punch 332, the burrs are first pressed down by the inclined first guide slope 5. When the wider top structure on the graphite plate 16 presses down, the burrs are cut or flattened. When the punch 332 falls completely, the burrs on the side of the product can be completely removed.
[0059] In a preferred embodiment, the stamping inner ring assembly 9 includes a first inner ring punch 91, a second inner ring punch 92, a third inner ring punch 93, a fourth inner ring punch 94, a fifth inner ring punch 95, and a sixth inner ring punch 96; the first inner ring punch 91, the second inner ring punch 92, and the third inner ring punch 93 are arranged in a row along the width direction of the stamping base 331 inside the third outer ring punch 43; the fourth inner ring punch 94, the fifth inner ring punch 95, and the sixth inner ring punch 96 are arranged in a row along the width direction of the stamping base 331 inside the fourth inner ring punch 94.
[0060] like Figure 3 As shown, the first inner ring punch 91, the second inner ring punch 92, and the third inner ring punch 93 are arranged in a row on the left side along the width direction of the stamping base 331. The first inner ring punch 91 is located at the front left side, the second inner ring punch 92 is located at the middle left side, and the third inner ring punch 93 is located at the rear left side. The first inner ring punch 91 corresponds to the through hole at the front left side of the graphite plate 16, and its shape is adapted to the shape of the through hole in the graphite plate 16. The second inner ring punch 92 corresponds to the through hole at the middle left side of the graphite plate 16, and its shape is adapted to the shape of the through hole in the graphite plate 16. The third inner ring punch 93 corresponds to the through hole at the rear left side of the graphite plate 16, and its shape is adapted to the shape of the through hole in the graphite plate 16. When the first inner ring punch 91, the second inner ring punch 92, and the third inner ring punch 93 press downwards, they can deburr the inner walls of the three through holes on the left side of the graphite plate 16, respectively.
[0061] Similarly, the fourth inner ring punch 94, the fifth inner ring punch 95, and the sixth inner ring punch 96 are arranged in a row on the right side along the width direction of the stamping base 331, with the fourth inner ring punch 94 located at the front right side, the fifth inner ring punch 95 located at the middle right side, and the sixth inner ring punch 96 located at the rear right side. The fourth inner ring punch 94 corresponds to the through hole at the front right side of the graphite plate 16, and its shape matches the shape of the through hole in the graphite plate 16. The fifth inner ring punch 95 corresponds to the through hole at the middle right side of the graphite plate 16, and its shape matches the shape of the through hole in the graphite plate 16. The sixth inner ring punch 96 corresponds to the through hole at the rear right side of the graphite plate 16, and its shape matches the shape of the through hole in the graphite plate 16. When the fourth inner ring punch 94, the fifth inner ring punch 95, and the sixth inner ring punch 96 press downwards, they can deburr the inner walls of the three through holes on the right side of the graphite plate 16, respectively.
[0062] In a preferred embodiment, the bottom periphery of the first inner ring punch 91 forms an inwardly inclined fifth guide slope 10; the bottom periphery of the second inner ring punch 92 forms an inwardly inclined sixth guide slope 11; the bottom periphery of the third inner ring punch 93 forms an inwardly inclined seventh guide slope 12; the bottom periphery of the fourth inner ring punch 94 forms an inwardly inclined eighth guide slope 13; the bottom periphery of the fifth inner ring punch 95 forms an inwardly inclined ninth guide slope 14; and the bottom periphery of the sixth inner ring punch 96 forms an inwardly inclined tenth guide slope 15.
[0063] like Figure 3 As shown, taking the first inner ring punch 91 as an example, the first inner ring punch 91 adopts a cuboid structure. The four sides of the bottom of the first inner ring punch 91 are respectively provided with inclined slopes. The four inclined slopes enclose the fifth guide slope 10 of the bottom of the first inner ring punch 91. This setting makes the bottom dimension of the first inner ring punch 91 smaller than the top dimension of the first inner ring punch 91. This not only helps the first inner ring punch 91 to press down without interference or collision between the bottom end of the first inner ring punch 91 and the graphite plate 16, but also allows the first inner ring punch 91 to press down smoothly. Under the structural action of the first inner ring punch 91 with a narrow bottom and a wide top, during the pressing process of the punch 332, the burrs in the corresponding through hole are first pressed down by the inclined fifth guide slope 10. When the wider top structure on the graphite plate 16 is pressed down, the burrs are cut or flattened. When the punch 332 falls completely, the burrs on the inner circumference of the product through hole can be completely removed.
[0064] In a preferred embodiment, the upper mold base 3 further includes a support column 34 and an upper template 35; the support column 34 is connected around the perimeter of the fixing plate 31, and the fixing plate 31 is connected to the top of the workbench 1 through the support column 34; the upper template 35 is connected to the bottom of the fixing plate 31.
[0065] like Figure 1 As shown, four support columns 34 are connected to the four corners of the top of the workbench 1. A fixing plate 31 is connected to the top of the support column 34, and an upper template 35 is connected to the bottom of the fixing plate 31. The upper template 35 is used to connect the drive mechanism 32. Therefore, the fixing plate 31 is fixedly connected to the top of the support column 34. In practical applications, in order to meet the needs of different heights, the support column 34 can also be set as a telescopic hydraulic rod, so that the height of the fixing plate 31 relative to the height of the workbench 1 can be adjusted. However, it is preferable to use a structure with a fixed length for the support column 34.
[0066] In a preferred embodiment, the lower mold base 2 includes support legs 21 and a lower template 22; the support legs 21 are connected around the lower template 22, and the lower template 22 is connected to the workbench 1 above the workbench 1 through the support legs 21; the height of the lower template 22 from the workbench 1 is less than the height of the support legs 21 from the workbench 1, so that a height difference is formed between the lower template 22 and the support legs 21 to form a mounting position for mounting the graphite plate 16 in the lower template 22.
[0067] The lower die base 2 is connected to the worktable 1 at a certain distance from the upper die base 3. The upper die base 3 is positioned above the lower die base 2, allowing the stamping mechanism 33 of the upper die base 3 to press the graphite plate 16 on the lower die base 2 downwards. One end of the support leg 21 is connected to the top surface of the worktable 1, and the other end of the support leg 21 is connected to the lower template 22. The lower template 22 is connected to the inner side of the four support legs 21, and the height of the lower template 22 is lower than the height of the support legs 21, so that a downwardly recessed structure is formed between the lower template 22 and the support legs 21, thereby forming an installation position for mounting the graphite plate 16 within the lower template 22. In use, the structure and shape of the lower template 22 are adapted to the structure and shape of the graphite plate 16 so that the graphite plate 16 can be accurately positioned when installed on the lower template 22 without the need for fixing and aligning. Since the height of the support leg 21 is higher than the height of the lower template 22, the inner side of the support leg 21 can limit the movement of the lower template 22 around its perimeter, preventing the graphite plate 16 inside the lower template 22 from shifting under the action of the stamping force, thereby achieving accurate positioning of the graphite plate 16.
[0068] Furthermore, a clearance groove is provided on the side where the support leg 21 connects to the lower template 22 to prevent interference when the stamping mechanism 33 presses downward; the clearance groove has an inner arc surface.
[0069] A clearance groove is provided at the connection point between the support leg 21 and the lower template 22, such as... Figure 1 As shown, the clearance groove has an arc-shaped groove structure. The shape of the clearance groove is adapted to the shape of the edge and corner of the graphite plate 16. The purpose is to form an installation position for the graphite plate 16 and achieve precise positioning of the graphite plate 16. On the one hand, it prevents interference with the graphite plate 16, and on the other hand, it can further prevent the graphite plate 16 from tilting.
[0070] In a preferred embodiment, the lower template 22 has punches corresponding to the through holes of the graphite plate 16, and the inner stamping ring assembly 9 can punch the holes to remove the burrs from the through holes of the graphite plate 16.
[0071] Specifically, the lower template 22 has six punches corresponding to the through holes of the graphite plate 16: a first punch, a second punch, a third punch, a fourth punch, a fifth punch, and a sixth punch. The first, second, and third punches are arranged in a row on the left side along the width of the lower template 22. The first punch corresponds to the first inner ring punch 91, the second punch corresponds to the second inner ring punch 92, and the third punch corresponds to the third inner ring punch 93. The fourth, fifth, and sixth punches are arranged in a row on the right side along the width of the lower template 22. The fourth punch corresponds to the fourth inner ring punch 94, the fifth punch corresponds to the fifth inner ring punch 95, and the sixth punch corresponds to the sixth inner ring punch 96.
[0072] In a preferred embodiment, the support leg 21 has a mounting hole extending along the height direction of the support leg 21, one end of which penetrates the side of the support leg 21 facing the upper mold base 3; the bottom wall of the mounting hole is connected to an elastic element.
[0073] To further improve the alignment stability between the upper die holder 3 and the lower die holder 2, a mounting hole is provided inside the support leg 21. The mounting hole is a countersunk hole, with one end not penetrating the support leg 21 and the top end penetrating the support leg 21. The purpose of the mounting hole is to correspond to the connecting rod 36 of the stamping mechanism 33 as described below. During the downward stamping process of the stamping mechanism 33, the outer ring assembly 4 stamps the outer ring of the graphite plate 16, and the inner ring assembly 9 stamps the through hole of the graphite plate 16. The connecting rod 36 can be inserted into the mounting hole, further stabilizing the connection between the stamping mechanism 33 and the lower die holder 2, so that the stamping mechanism 33 will not deviate during the downward stamping process, thereby further improving the stamping stability and the deburring quality.
[0074] In a preferred embodiment, the stamping mechanism 33 further includes a connecting rod 36; the connecting rod 36 is connected to the four corners of the stamping base 331, and the connecting rod 36 is provided corresponding to the mounting hole; the connecting rod 36 can extend into the mounting hole when the stamping mechanism 33 presses downward.
[0075] The bottom of the connecting rod 36 can be connected to an elastic element, which can be a spring or a structural component made of elastic material. The purpose is to avoid rigid friction and impact between the connecting rod 36 and the bottom wall of the mounting hole during the insertion of the connecting rod 36 into the mounting hole, thereby improving the overall safety and quality performance of the stamping mechanism 33.
