Description

Technical Field

[0001] The present invention relates to the technical field of carbon product production, and particularly relates to a carbon cold pressing forming device and a forming method. Background Art

[0002] Carbon cold pressing forming is to use a pressing device to press the mixed carbon powder to obtain a carbon powder pressed product. Due to the characteristics of good chemical stability, high temperature resistance, corrosion resistance, self-lubrication, low elastic modulus, and good conductivity of carbon materials, they are widely used in the fields of chemical industry, electric power, mining machinery, environmental governance, etc.

[0003] Since there are gaps between carbon powder particles and the gaps are filled with air, there will be many pores inside the carbon powder pressed product obtained by directly pressing carbon powder with a pressing device. The existence of pores leads to low compactness between carbon powders, affecting the density, mechanical (wear) strength, and material properties of the carbon powder pressed product.

[0004] In order to obtain high-quality carbon powder pressed products and improve the profitability of carbon powder pressed product production enterprises, the common method currently adopted by carbon powder pressed product production enterprises is to add a degassing process before pressing carbon powder. For example, the patent with the publication number CN114851624B records removing the air in the gaps of carbon powder by pressurizing and evacuating the carbon powder, and another example is the patent with the publication number CN201728859U which records removing the air in the gaps of carbon powder by vibrating the carbon powder.

[0005] After the above degassing process is used, the number of pores in the carbon powder pressed product is reduced, and the quality of the carbon powder pressed product is improved. However, some new problems have also arisen, affecting the production of carbon powder pressed products. For example, the carbon cold pressing forming device redesigned in the patent with the publication number CN114851624B can only produce one carbon powder pressed product each time, with low production efficiency. Another example is that after adding the vibration degassing process in the patent with the publication number CN201728859U, the holes through which the positioning columns 5 penetrate on the upper die 1, middle die 2, and lower die 3 will be worn and deformed, making the positioning columns 5 prone to shaking on the upper die 1, middle die 2, and lower die 3, seriously affecting the sliding fit accuracy between the positioning columns 5 and the upper die 1, middle die 2, and lower die 3, and reducing the service life of the carbon cold pressing forming die.

[0006] Based on this, the present invention is designed. Summary of the Invention

[0007] The main object of the present invention is to propose a carbon cold pressing forming device and a forming method, aiming to solve the problems of decreased production efficiency and service life of the existing carbon cold pressing forming device after adding the degassing process.

[0008] To solve the above problems, the present invention provides a carbon cold pressing forming device, which includes a centrifugal table and a rotating ring rotatably installed on the upper surface of the centrifugal table around the vertical axis. The rotating ring is in transmission connection with a first motor, and the first motor drives the rotating ring to rotate. The rotating ring is fixedly connected with a plurality of cantilevers symmetrically distributed around the rotating ring as the center. One end of each cantilever away from the rotating ring is hinged with a connecting plate. When the rotating ring does not rotate, the connecting plate remains vertical under its own weight. When the rotating ring rotates, the connecting plate can be kept horizontal under the action of centrifugal force. A mold cylinder is installed on each connecting plate. When the connecting plate is vertical, pressing plates are arranged directly above and below each mold cylinder. The pressing plates are connected with a lifting device, and the lifting device is fixedly connected with the outer circumferential surface of the centrifugal table. The mold cylinder is provided with a through hole up and down. A slide plate is slidably and sealingly installed up and down in the mold cylinder. The lifting device drives the pressing plates to extend into the mold cylinder from the upper and lower ends of the mold cylinder to extrude the carbon powder in the mold cylinder.

[0009] In one embodiment, the vertical connecting plate is arranged at an interval from the outer circumferential surface of the centrifugal table, and the mold cylinder is located between the vertical connecting plate and the outer circumferential surface of the centrifugal table.

[0010] The upper end of the vertical connecting plate is hinged with one end of the cantilever away from the rotating ring, and the lower end of the vertical connecting plate is connected with the mold cylinder and a counterweight. The mold cylinder and the counterweight are arranged on both sides of the lower end of the vertical connecting plate.

[0011] In one embodiment, a through hole one penetrating the mold cylinder is arranged at the bottom of the mold cylinder. The aperture of the through hole one is smaller than the inner diameter of the mold cylinder, and the slide plate slides up and down closely against the inner wall of the mold cylinder.

[0012] In one embodiment, a feed hole and a mounting hole one are arranged on the upper surface of the centrifugal table. A first motor and a first gear ring are arranged in the mounting hole one. The first gear ring is tightly sleeved on the rotating ring, and the first motor is in transmission connection with the first gear ring.

[0013] In one embodiment, a protrusion is arranged at the bottom of the feed hole. The lowest part of the bottom of the feed hole is provided with a number of material conveying pipes equal to the number of mold cylinders. The material conveying pipes are inclined. The upper end of the material conveying pipe is located at the lowest part of the bottom of the feed hole. The lower end of the material conveying pipe extends out from the outer circumferential surface of the centrifugal table and is located directly above the mold cylinder. The carbon powder flowing out from the lower end of the material conveying pipe falls into the mold cylinder.

[0014] In one embodiment, a baffle is vertically fixed on the edge of the upper surface of the pressing plate above the mold cylinder. The pressing plate and the baffle can closely slide vertically against the lower end of the material conveying pipe to block the lower end of the material conveying pipe.

[0015] A number of material conveying pipes, mold cylinders, and connecting plates are symmetrically distributed around the rotating ring as the center.

[0016] In one embodiment, the die barrel and the connecting plate are connected by a connecting member. The connecting member includes a first prism and a retaining piece fixed to one end of the first prism. A rectangular through hole is provided on the connecting plate. A pair of clamping blocks are slidably installed in the rectangular through hole. After the pair of clamping blocks come into contact with each other, they jointly define a through square hole for the first prism to pass through. The hole wall of the through square hole is in close contact with the outer surface of the first prism. The clamping blocks are connected to a first spring. The first spring is used to push the pair of clamping blocks to approach and contact each other. After the first prism passes through the through square hole, it is fixedly connected to the die barrel. The rotation of the first prism drives the die barrel to rotate around the first prism. At the same time, it pushes the pair of clamping blocks to slide away from each other and compresses the first spring.

[0017] In one embodiment, on one side of the outer circumferential surface of each die barrel facing the centrifugal table, a square socket is provided;

[0018] The lower surface of the centrifugal table is recessed inward to form a second mounting hole. At the bottom of the second mounting hole, a coaxial first annular groove, a second annular groove, and a third mounting hole are provided. A third lifting device is vertically and fixedly installed at the bottom of the third mounting hole. A top block connected to the third lifting device is provided in the third mounting hole. The side surface of the top block is an inclined surface. A second through hole coaxial with the square socket is provided on the hole wall of the third mounting hole. The number of the second through holes is equal to the number of die barrels. The multiple second through holes are centrosymmetrically distributed around the swivel ring. One end of the second through hole extends to the outer circumferential surface of the centrifugal table. A second prism is axially slidably installed in each second through hole. One end of the second prism extends into the third mounting hole and contacts the inclined surface. The third lifting device drives the top block to move up or down, which can push all the second prisms to axially slide in the second through holes, so that the other end of each second prism is inserted into the corresponding square socket;

[0019] The second through hole penetrates through the first annular groove and the second annular groove. In the first annular groove, a number of second springs and slip rings equal to the number of second prisms are provided. The multiple slip rings are sleeved on the respective second prisms and can slide axially and rotate around the second prisms. A positioning pin fixedly connected to the second prism is provided on one side of the slip ring. A second spring is connected to the other side of the slip ring. During the process of the second prism axially moving and inserting into the square socket, the positioning pin pushes the slip ring to compress the second spring. When the top block moves up or down and releases the push on the second prism, the second spring pushes the second prism to axially move away from the square socket through the slip ring and the positioning pin;

[0020] In the second annular groove, a second gear ring and a number of third gears equal to the number of second prisms are provided. The multiple third gears are axially sleeved on the respective second prisms. The multiple third gears are engaged with the second gear ring. The third gears are in transmission connection with a second motor. The second motor is fixedly installed in the second mounting hole. The second motor drives the third gears to rotate, and then drives each second prism to rotate;

[0021] The rotation of the rotating ring can make prism 1 and prism 2 coaxial. When prism 2 is coaxial with prism 1 and the other end of prism 2 is inserted into the corresponding square socket, the rotation of prism 2 drives the mold cylinder to rotate around prism 1.

[0022] In one embodiment, it also includes a loading device and a conveying device, wherein the loading device is capable of adding carbon powder to the feed hole, and the conveying device is located directly below the mold cylinder when the mold cylinder rotates around the prism. When the mold cylinder rotates 180 degrees around the prism, the carbon powder pressed product in the mold cylinder can slide out of the mold cylinder and fall onto the conveying device for transportation.

[0023] In addition, the present invention also proposes a carbon cold pressing forming method, which uses the aforementioned carbon cold pressing forming equipment to perform the following steps:

[0024] Control the feeding device to add carbon powder into the feeding hole;

[0025] The pressure plate above the mold barrel is controlled to rise and open the feeding pipe, so that the feeding pipe can be used to add carbon powder into the mold barrel. After the filling is completed, the pressure plate above the mold barrel is controlled to move downward, and the lower end of the feeding pipe is blocked by the pressure plate and the baffle on it.

[0026] Start motor 1, control the rotation speed of the swivel to gradually increase, and drive the mold barrel to rotate upward around the hinge point of the connecting plate and the cantilever until the rotation angle of the mold barrel reaches 90 degrees. Then keep the swivel rotating at a constant speed, so that the carbon powder in the mold barrel is squeezed against each other and the air in the gap between the carbon powder is squeezed out;

[0027] After a period of time, the speed of the control ring's rotation gradually drops to zero, and the mold barrel then rotates 90 degrees downward around the hinge point between the connecting plate and the cantilever to reset;

[0028] The rotating ring is controlled to rotate to move the mold barrel between the upper and lower pressing plates, and then the pressing plates directly above and below the mold barrel are controlled to move vertically into the mold barrel to extrude the carbon powder to produce carbon powder pressed products;

[0029] The rotating ring is controlled to rotate so that prism 1 and prism 2 are coaxial, and then the top block is controlled to move upward or downward so that one end of prism 2 is inserted into the corresponding square socket. Motor 2 is started to drive prism 2 to rotate so that the mold barrel rotates 180 degrees around prism 1. The carbon powder pressed product in the mold barrel slides out of the mold barrel and falls onto the conveying device for delivery;

[0030] After the carbon powder pressed product slides out of the mold barrel, start motor 2 to drive prism 2 to rotate, so that the mold barrel rotates 180 degrees around prism 1 and resets. Then control the rotation of the swivel to move the mold barrel between the upper and lower pressure plates, open the feed pipe, and continue to use the feed pipe to add carbon powder into the mold barrel.

[0031] Beneficial effect: The technical solution of the present invention drives multiple mold cylinders to rotate at high speed through the rotation of the rotating ring.

[0032] The inertia of centrifugal force is used to squeeze the carbon powder in the mold barrel into compaction, squeeze out the air in the gap of the carbon powder, and achieve the purpose of degassing. Then the carbon powder in the mold barrel is squeezed by the pressure plate to produce a carbon powder pressed product. The carbon powder in the mold barrel is automatically filled by the feed pipe. The prepared carbon powder pressed product is controlled to slide onto the conveying device by rotating the mold barrel 180 degrees and is sent away by the conveying device. The automatic filling of carbon powder and automatic unloading of carbon powder pressed products are realized in the entire production process of carbon powder pressed products. There are many mold barrels, and multiple carbon powder pressed products can be produced at the same time. The production speed is fast and the efficiency is high. The swivel drives multiple mold barrels to rotate at high speed, which has little impact on various components of the equipment. Therefore, the carbon cold pressing molding equipment of the present invention has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention provides a carbon cold pressing and forming device. The carbon cold pressing and forming device drives a plurality of die cylinders 22 to rotate at high speed through the rotation of a rotating ring 5. By using the inertial action of centrifugal force, the carbon powder materials in the die cylinders 22 are mutually extruded and compacted, and the air in the gaps of the carbon powder materials is extruded to achieve the purpose of degassing. Then, a pressing plate is used to extrude the carbon powder materials in the die cylinders 22 to obtain carbon powder pressed products. The carbon powder materials in the die cylinders 22 are automatically filled through a feeding pipe 4. The obtained carbon powder pressed products are made to slide onto a conveying device 42 automatically by controlling the rotation of the die cylinders 22 by 180 degrees, and are sent away by the conveying device 42. During the entire production process of the carbon powder pressed products, automatic filling of the carbon powder materials and automatic blanking of the carbon powder pressed products are realized. The number of die cylinders 22 is large, and multiple carbon powder pressed products can be obtained simultaneously at one time. The production speed is fast and the efficiency is high. The rotation of the rotating ring 5 driving a plurality of die cylinders 22 at high speed has extremely little influence on each component of the device. Therefore, the carbon cold pressing and forming device of the present invention has a long service life.

[0047] Specifically, in an embodiment of the invention, the carbon cold pressing and forming device includes a centrifugal table 1 and a rotating ring 5 rotatably installed on the upper surface of the centrifugal table 1 around a vertical axis. As Figures 1-4 shown, the centrifugal table 1 is of a cylindrical structure. Preferably, the rotating ring 5 is coaxially arranged with the centrifugal table 1.

[0048] Specifically, as Figure 3 shown, an annular groove for installing the rotating ring 5 is coaxially arranged on the upper surface of the centrifugal table 1. A thrust bearing 7 is installed at the bottom of the annular groove. The lower end of the rotating ring 5 extends into the annular groove and is supported and fixed by the thrust bearing 7. Such a design helps the rotating ring 5 to rotate stably at high speed, improves the rotational stability of the rotating ring 5 and the die cylinders 22, reduces the influence of the rotation of the rotating ring 5 driving a plurality of die cylinders 22 at high speed on each component of the device, and is beneficial to extending the service life of the carbon cold pressing and forming device.

[0049] In this embodiment, the swivel ring 5 is in transmission connection with the first motor 11, and the first motor 11 drives the swivel ring 5 to rotate self - sufficiently. Preferably, the first motor 11 is in transmission connection with the swivel ring 5 through a speed reducer 10. With such a design, it is convenient to make the centrifugal table 1 and the swivel ring 5 large enough, thereby increasing the number of arrangements of the cantilever 13, the connecting plate 14, and the die cylinder 22, and improving the production efficiency of the carbon powder pressed product.

[0050] Specifically, as Figures 1-4 shown, a first mounting hole 8 is formed by the inward depression of the upper surface of the centrifugal table 1. The first mounting hole 8 is an annular hole and is coaxial with the centrifugal table 1. The speed reducer 10 and the first motor 11 are both arranged in the first mounting hole 8. A first gear ring 6 is also arranged in the first mounting hole 8. The first gear ring 6 is tightly sleeved outside the swivel ring 5. As Figure 4 shown, the speed reducer 10 is meshed with the first gear ring 6 through a first gear 9, and the speed reducer 10 is also meshed with the first motor 11. After the first motor 11 is started, it drives the first gear ring 6 to rotate self - sufficiently through the speed reducer 10 and the first gear 9, and then drives the swivel ring 5 to rotate self - sufficiently.

[0051] Furthermore, to prevent dust and other sundries from falling into the first mounting hole 8 and affecting the transmission structure of the first motor 11 driving the swivel ring 5 to rotate self - sufficiently, a cover 12 can be detachably and fixedly installed on the upper surface of the centrifugal table 1.

[0052] In this embodiment, as Figures 1-4 shown, the swivel ring 5 is fixedly connected with a plurality of cantilevers 13 that are centrally symmetrically distributed with the swivel ring 5 as the center. One end of each cantilever 13 away from the swivel ring 5 is hinged with a connecting plate 14. Preferably, the cantilever 13 extends along the radial direction of the centrifugal table 1. With such a design, it is convenient to make the cantilever 13 obtain the technical effect that the connecting plate 14 is vertically arranged and is spaced from the centrifugal table 1 at the shortest distance, which is convenient for subsequently arranging the lower pressing plate 26 and the die cylinder 22 between the connecting plate 14 and the centrifugal table 1. Because only by arranging the lower pressing plate 26 and the die cylinder 22 between the connecting plate 14 and the centrifugal table can it not affect the connecting plate 14 to drive the die cylinder 22 to swing upward around one end of the cantilever 13 away from the swivel ring 5 while rotating under the action of the first motor 11 and centrifugal force.

[0053] [[ID=W18]]In this embodiment, as Figures 1-4 shown, when the swivel ring 5 does not rotate, the connecting plate 14 remains vertical under the action of its own weight. When the swivel ring 5 rotates, the connecting plate 14 can swing upward around one end of the cantilever 13 away from the swivel ring 5 under the action of centrifugal force until the connecting plate 14 rotates 90 degrees upward from the vertical position around one end of the cantilever 13 away from the swivel ring 5 to the horizontal position and continuously remains horizontal;

[0054] When the rotation speed of the swivel 5 starts to decrease, the connecting plate 14 in the horizontal position begins to rotate downward by 90 degrees around the end of the cantilever 13 away from the swivel 5 to reset. After the swivel 5 stops rotating, the connecting plate 14 returns to the vertical position.

[0055] In this embodiment, as Figures 1-4 shown, a die cylinder 22 is installed on each connecting plate 14. When the connecting plate 14 is vertical, the die cylinder 22 is also vertically arranged. Specifically, the vertical connecting plate 14 is spaced from the outer circumferential surface of the centrifugal table 1, and the die cylinder 22 is located between the vertical connecting plate 14 and the outer circumferential surface of the centrifugal table 1; the upper end of the vertical connecting plate 14 is hinged to the end of the cantilever 13 away from the swivel 5, and the lower end of the vertical connecting plate 14 is connected to the die cylinder 22 and the counterweight 21. The die cylinder 22 and the counterweight 21 are arranged on both sides of the lower end of the vertical connecting plate 14. With such a design, the connecting plate 14 can be kept vertical under its own weight with the help of the counterweight 21 when the swivel 5 is not rotating. When the connecting plate 14 is kept vertical, the die cylinder 22 is also vertical. With such a design, it is convenient for the lower pressing plate 26 and the lifting plate 29 to move vertically into the die cylinder 22 to press the carbon powder to obtain the carbon powder pressed product.

[0056] In this embodiment, when the die cylinder 22 is vertically arranged, pressing plates are arranged above and below each die cylinder 22. Specifically, as Figures 1-4 shown, the pressing plate located directly above the die cylinder 22 is denoted as the lower pressing plate 26. The lower pressing plate 26 is connected to the lifting device 1 25. The lifting device 1 25 is vertically and fixedly installed on the mounting seat 30. The mounting seat 30 is fixedly connected to the outer circumferential surface of the centrifugal table 1. The lifting device 1 25 can drive the lower pressing plate 26 to descend into the die cylinder 22 to extrude the carbon powder.

[0057] The pressing plate located directly below the die cylinder 22 is denoted as the lifting plate 29. The lifting plate 29 is connected to the lifting device 2 28. The lifting device 2 28 is vertically and fixedly installed on another mounting seat 30. This mounting seat 30 is also fixedly connected to the outer circumferential surface of the centrifugal table 1. As Figure 4 shown, the die cylinder 22 is provided with a through hole up and down. A through hole 23 that penetrates the die cylinder 22 is provided at the bottom of the die cylinder 22. The diameter of the through hole 23 is smaller than the inner diameter of the die cylinder 22. A sliding plate 24 is installed in the die cylinder 22 to slide up and down in a sealed manner. The sliding plate 24 slides up and down closely against the inner wall of the die cylinder 22. The diameter of the through hole 23 being smaller than the inner diameter of the die cylinder 22 prevents the sliding plate 24 from falling out of the bottom of the die cylinder 22. The lifting device 2 28 can drive the lifting plate 29 to rise into the die cylinder 22 to push the sliding plate 24 to rise and cooperate with the lower pressing plate 26 to extrude the carbon powder to obtain the carbon powder pressed product.

[0058] In this embodiment, as Figure 4As shown in the figure, since the connecting plate 14 and the centrifugal table 1 are arranged at intervals, there is a suitable position to install and arrange the first lifting device 25, the second lifting device 28, the lower pressing plate 26, and the jacking plate 29. Subsequently, the first lifting device 25, the second lifting device 28, the lower pressing plate 26, and the jacking plate 29 do not affect the rotation of the connecting plate 14 and the mold cylinder 22 driven by the first motor 11 while swinging upward around one end of the cantilever 13 away from the rotating ring 5. Moreover, when the first motor 11 stops rotating, the connecting plate 14 and the mold cylinder 22 can return from the horizontal position to the vertical position. In addition, by means of the first motor 11, the positions of the connecting plate 14 and the mold cylinder 22 can also be adjusted so that the mold cylinder 22 is located between the lower pressing plate 26 and the jacking plate 29, facilitating the timely action of the lower pressing plate 26 and the jacking plate 29 to extend into the mold cylinder 22 to extrude the carbon powder after the connecting plate 14 and the mold cylinder 22 return from the horizontal position to the vertical position, thereby obtaining carbon powder compacts.

[0059] It can be seen that the carbon cold pressing forming equipment of this embodiment is provided with a plurality of mold cylinders 22. When the first motor 11 is started once, the carbon powder in a plurality of mold cylinders 22 can be degassed simultaneously. After the degassing is completed, the connecting plate 14 and the mold cylinders 22 return from the horizontal position to the vertical position. The lower pressing plate 26 and the jacking plate 29 above and below each mold cylinder 22 can act simultaneously to extend into the mold cylinder 22 to extrude the carbon powder to obtain carbon powder compacts, so that multiple carbon powder compacts can be obtained simultaneously at one time, with a fast production speed and high efficiency, which is conducive to reducing production costs.

[0060] Furthermore, in this embodiment, as Figures 1-4 shown, a feed hole 2 is coaxially arranged on the upper surface of the centrifugal table 1, and a protrusion 3 is arranged at the bottom of the feed hole 2. Such a design facilitates the smooth flow of the carbon powder in the feed hole 2 into the feed pipe 4 and prevents it from accumulating at the bottom of the feed hole 2. The lowest part of the bottom edge of the feed hole 2 is provided with a feed pipe 4 whose number is equal to the number of mold cylinders 22. As Figure 4 shown, the feed pipe 4 is inclined. The upper end of the feed pipe 4 is located at the lowest part of the bottom of the feed hole 2, and the lower end of the feed pipe 4 extends out from the outer circumferential surface of the centrifugal table 1 and is located directly above the mold cylinder 22. Such a design enables the carbon powder in the feed hole 2 to flow smoothly through the feed pipe 4 and be injected into the mold cylinder 22, and the carbon powder flowing out from the lower end of the feed pipe 4 can fall into the mold cylinder 22. The lower end pipe orifice of the feed pipe 4 is vertically flush with the inner wall of the mold cylinder 22. Such a design ensures that the lower end of the feed pipe 4 does not block or affect the up and down movement of the lower pressing plate 26.

[0061] Furthermore, as Figure 1 and Figure 4As shown, a baffle 27 is vertically fixed on the edge of the upper surface of the lower pressing plate 26. The lower pressing plate 26 and the baffle 27 can slide vertically close to the lower end pipe orifice of the material conveying pipe 4. Such a design not only does not affect the vertical movement of the lower pressing plate 26 to cooperate with the jacking plate 29 to extrude the carbon powder to obtain a carbon powder pressed product, but also can use the lower pressing plate 26 and the baffle 27 to block the lower end pipe orifice of the material conveying pipe 4, avoiding the carbon powder flowing out from the lower end of the material conveying pipe 4 after the die cylinder 22 leaves the lower end of the material conveying pipe 4;

[0062] When it is necessary to inject carbon powder into the die cylinder 22, control the lower pressing plate 26 to rise and separate from the lower end pipe orifice of the material conveying pipe 4. When it is not necessary to inject carbon powder into the die cylinder 22, control the lower pressing plate 26 to descend, and use the lower pressing plate 26 and the baffle 27 to block the lower end pipe orifice of the material conveying pipe 4, and it does not affect the lower pressing plate 26 extending into the die cylinder 22 to cooperate with the jacking plate 29 to extrude the carbon powder to obtain a carbon powder pressed product.

[0063] Preferably, multiple material conveying pipes 4, die cylinders 22, and connecting plates 14 are symmetrically distributed around the swivel ring 5. One die cylinder 22 corresponds to one material conveying pipe 4. Such a design can realize injecting carbon powder into multiple die cylinders 22 at the same time. Further, as Figure 4 shown, the carbon cold pressing forming equipment further has a feeding device 41. The carbon powder is injected into the feeding hole 2 through the feeding device 41, thereby realizing the full-automatic feeding of the carbon powder and further improving the production efficiency of the carbon powder pressed product. Commonly, the feeding device 41 can be a conventional powder conveying device such as a belt conveyor or a screw elevator.

[0064] Further, in this embodiment, as Figures 1-4 shown, the die cylinder 22 and the connecting plate 14 are connected by a connecting member 15. As Figure 5 shown, the connecting member 15 includes a first prism 151 and a retaining piece fixed at one end of the first prism 151. The other end of the first prism 151 is fixedly connected to the die cylinder 22. The first prism 151 penetrates through the connecting plate 14. The existence of the retaining piece ensures that the first prism 151 will not slip off from the connecting plate 14, ensuring the reliable connection between the die cylinder 22 and the connecting plate 14. As Figure 6As shown, a rectangular through-hole 16 is provided on the connecting plate 14. A pair of clamping blocks 17 are slidably installed in the rectangular through-hole 16. After the pair of clamping blocks 17 come into contact with each other, they jointly define a through-square hole 19 for the first prism 151 to pass through. Moreover, the hole wall of the through-square hole 19 is in close contact with the outer surface of the first prism 151. With such a design, the self-rotation of the first prism 151 will squeeze the pair of clamping blocks 17 in close contact to move and separate from each other. In addition, the clamping blocks 17 are connected to the first spring 18, and the first spring 18 is used to push the pair of clamping blocks 17 to approach and contact each other, thereby preventing the first prism 151 from rotating easily. With such a design, a relatively large force is required to drive the first prism 151 to rotate self to squeeze the pair of clamping blocks 17 in close contact to move and separate from each other. After the first prism 151 passes through the through-square hole 19, it is fixedly connected to the die cylinder 22. Therefore, when no external force is applied to the die cylinder 22, the die cylinder 22 and the connecting plate 14 are fixedly connected by the connecting member 15, and the die cylinder 22 will not rotate around the first prism 151 on the connecting plate 14. The die cylinder 22 and the connecting plate 14 are fixedly connected as a whole. Of course, when a certain magnitude of external force is applied to the die cylinder 22, the die cylinder 22 can rotate around the first prism 151. At the same time, the pair of clamping blocks 17 are pushed to slide away from each other and the first spring 18 is compressed. After the external force is removed, the first spring 18 compresses the pair of clamping blocks 17 to resume close contact, so that the first prism 151 stops rotating, and the die cylinder 22 and the connecting plate 14 resume fixed connection. With such a design, when the die cylinder 22 makes a carbon powder pressed product and the die cylinder 22 needs to discharge the material, a certain magnitude of external force is applied to the die cylinder 22 to make the die cylinder 22 rotate 180 degrees around the first prism 151 to pour out the carbon powder pressed product in the die cylinder 22. After pouring out the carbon powder pressed product in the die cylinder 22, then make the die cylinder 22 rotate 180 degrees around the first prism 151 to reset. In this way, the full-automatic feeding of the carbon powder pressed product can be realized, and the production efficiency of the carbon powder pressed product is further improved.

[0065] Specifically, as Figure 4 shown, on one side of the outer circumferential surface of each die cylinder 22 facing the centrifugal table 1, a square socket 20 is provided. The square socket 20 is coaxially arranged with the first prism 151. With such a design, it is convenient for the second prism 37 to slide into the square socket 20, and then by controlling the self-rotation of the second prism 37, the die cylinder 22 can be driven to rotate around the first prism 151.

[0066] In this embodiment, as Figure 3 and Figure 4As shown, a second mounting hole 32 is formed by inward depression on the lower surface of the centrifuge table 1. The second mounting hole 32 is coaxial with the centrifuge table 1. At the bottom of the second mounting hole 32, a first annular groove 33, a second annular groove 34, and a third mounting hole 36 are coaxially arranged. A third lifting device 39 is vertically and fixedly installed at the bottom of the third mounting hole 36. A top block 38 connected to the third lifting device 39 is arranged in the third mounting hole 36. The third lifting device 39 drives the top block 38 to vertically lift and lower in the third mounting hole 36. The side surface of the top block 38 is an inclined surface. With such a design, it is convenient for the top block 38 to push the second prism 37 to horizontally move axially when moving vertically. Preferably, the top block 38 is in a conical shape.

[0067] In this embodiment, as Figure 3 and Figure 4 shown, a second through hole 43 is arranged on the hole wall of the third mounting hole 36. The second through hole 43 extends along the radial direction of the centrifuge table 1. As Figure 1 shown, one end of the second through hole 43 extends to the outer circumferential surface of the centrifuge table 1. The number of the second through holes 43 is equal to the number of the die cylinders 22. The multiple second through holes 43 are centrosymmetrically distributed with the swivel ring 5 as the center. Preferably, the second through holes 43 and the feeding pipes 4 are arranged at intervals. As Figure 2 shown, one second through hole 43 is arranged between two adjacent feeding pipes 4. A second prism 37 is axially slidably installed in each second through hole 43. One end of the second prism 37 extends into the third mounting hole 36 and contacts the inclined surface. When the third lifting device 39 drives the top block 38 to move upward or downward, it can push all the second prisms 37 to horizontally slide axially in the second through holes 43. When the swivel ring 5 rotates, the second through holes 43 can be coaxial with the square jacks 20. At this time, when all the second prisms 37 horizontally slide axially in the second through holes 43, the other end of each second prism 37 can be inserted into the corresponding square jack 20. Then, by controlling the rotation of all the second prisms 37, the simultaneous control of all the die cylinders 22 to rotate and discharge materials around the first prism 151 can be realized, further improving the discharging efficiency of the carbon powder pressed products.

[0068] In this embodiment, as Figure 3 and Figure 4 shown, the second through hole 43 penetrates through the first annular groove 33 and the second annular groove 34. In the first annular groove 33, a second spring 45 and a sliding ring 44 with the same number as the second prisms 37 are arranged. Each second prism 37 is sleeved with a second spring 45 and a sliding ring 44. The second spring 45 and the sliding ring 44 can slide axially and rotate along the second prism 37. As Figure 3As shown, a positioning pin 46 fixedly connected to the second prism 37 is provided on one side of the slip ring 44, and a second spring 45 is connected to the other side of the slip ring 44. During the axial movement of the second prism 37 and its insertion into the square jack 20, the positioning pin 46 pushes the slip ring 44 to compress the second spring 45. When the top block 38 moves upward or downward to release the push on the second prism 37, the second spring 45 then pushes the second prism 37 axially through the slip ring 44 and the positioning pin 46 to separate from the square jack 20 and retract into the second through hole 43, thereby realizing the horizontal reciprocating movement of the second prism 37. When the mold cylinder 22 needs to discharge materials, one end of the second prism 37 is controlled to extend out of the second through hole 43 and insert into the square jack 20. After the discharging is completed, the second prism 37 is then controlled to separate from the square jack 20 and retract into the second through hole 43, without affecting the rotation of the rotating ring 5 driving the mold cylinder 22.

[0069] In this embodiment, as Figure 3 and Figure 4 shown, a second gear ring 35 and a number of third gears 47 equal to the number of the second prisms 37 are provided in the second annular groove 34. Each second prism 37 is axially slidably mounted with a third gear 47, and the third gear 47 cannot axially move in the second annular groove 34. The second gear ring 35 is rotatably mounted in the second annular groove 34, and a plurality of third gears 47 are all meshed with the second gear ring 35. As Figure 3 shown, one of the third gears 47 is meshed and drivingly connected with a second gear 48 mounted on the second motor 40. The second motor 40 is fixedly provided in the second mounting hole 32. By driving the third gear 47 to rotate by the second motor 40, and then driving each second prism 37 to rotate synchronously by means of the second gear ring 35, the discharge of all the mold cylinders 22 around the first prism 151 is simultaneously controlled, further improving the discharge efficiency of the carbon powder pressed products.

[0070] In this embodiment, the rotation of the swivel ring 5 can coaxialize the first prism 151 and the second prism 37. When the second prism 37 is coaxial with the first prism 151 and the other end of the second prism 37 is inserted into the corresponding square jack 20, the self-rotation of the second prism 37 can drive the mold cylinder 22 to rotate around the first prism 151 to realize the automatic blanking of the carbon powder pressed product. Specifically, after the lower pressing plate 26 extends into the mold cylinder 22 and cooperates with the lifting plate 29 to extrude the carbon powder to obtain the carbon powder pressed product, the swivel ring 5 rotates to coaxialize the first prism 151 and the second prism 37. Then, the top block 38 moves upward or downward to push the second prism 37 into the square jack 20. Then, the second motor 40 is started to drive the mold cylinder 22 to rotate 180 degrees to complete the blanking of the carbon powder pressed product. After the blanking is completed, the second motor 40 is started again to drive the mold cylinder 22 to rotate 180 degrees to reset. Then, the top block 38 resets, and the second spring 45 pushes the second prism 37 to separate from the square jack 20 and retract into the second through hole 43. Then, the swivel ring 5 continues to rotate to drive the mold cylinder 22 to move between the lower pressing plate 26 and the lifting plate 29, that is, below the lower end of the feed pipe 4, waiting for the feed pipe 4 to refill the carbon powder into the mold cylinder 22 again. With this design, the continuous production of the carbon powder pressed product can be realized, and the production efficiency of the carbon powder pressed product can be further improved.

[0071] Further, the carbon cold pressing forming device further includes a conveying device 42. As Figure 3 shown, the conveying device 42 is located directly below the position where the mold cylinder 22 is located when the mold cylinder 22 rotates around the first prism 151. When the mold cylinder 22 rotates 180 degrees around the first prism 151, the carbon powder pressed product in the mold cylinder 22 can slide out of the mold cylinder 22 and fall onto the conveying device 42 to be sent away. Commonly, the conveying device 42 is a belt conveyor, a roller conveyor, etc.

[0072] In this embodiment, as Figure 3 and Figure 4 shown, a base 31 is provided at the bottom of the centrifugal table 1. With this design, the lower surface of the centrifugal table 1 can be lifted a certain distance above the ground, which is convenient for wiring.

[0073] In addition, the present invention also proposes a carbon cold pressing forming method, which uses the aforementioned carbon cold pressing forming device to perform the following steps:

[0074] S1. Control the feeding device 41 to feed carbon powder into the feeding hole 2;

[0075] S2. Control the pressing plate directly above the mold cylinder 22 to rise to open the feed pipe 4, so that the feed pipe 4 feeds carbon powder into the mold cylinder 22. After the feeding is completed, control the pressing plate directly above the mold cylinder 22 to move down, and use the pressing plate and the baffle 27 thereon to block the lower end of the feed pipe 4;

[0076] S3. Start Motor 11, and gradually increase the rotational speed of the rotating ring 5 for self-rotation to drive the die barrel 22 to rotate upward around the hinge point of the connecting plate 14 and the cantilever 13 until the rotation angle of the die barrel 22 reaches 90 degrees. Then, keep the rotating ring 5 rotating at a constant speed to make the carbon powder in the die barrel 22 extrude each other, fully squeezing out the air in the gaps of the carbon powder. At this time, both the die barrel 22 and the connecting plate 14 are horizontal;

[0077] S4. After a period of time, the degassing is completed. At this time, gradually decrease the self-rotation speed of the rotating ring 5 to zero. During this process, the die barrel 22 rotates downward by 90 degrees around the hinge point of the connecting plate 14 and the cantilever 13 to reset, and the reset position is as Figure 4 shown;

[0078] S5. Control the self-rotation of the rotating ring 5 to move and adjust the die barrel 22 between the upper and lower pressing plates (if the die barrel 22 is already between the upper and lower pressing plates, this step can be omitted). Then, control the pressing plates directly above and below the die barrel 22 to move vertically into the die barrel 22 to extrude the carbon powder, and obtain the carbon powder pressed product;

[0079] S6. Control the self-rotation of the rotating ring 5 to make Prism 151 and Prism 37 coaxial. Then, control the top block 38 to move upward or downward so that one end of Prism 37 is inserted into the corresponding square jack 20. Start Motor 2 40 to drive Prism 37 to rotate self, making the die barrel 22 rotate 180 degrees around Prism 151. The carbon powder pressed product in the die barrel 22 slides out of the die barrel 22 and falls onto the conveying device 42 to be sent away;

[0080] S7. After the carbon powder pressed product slides out of the die barrel 22, start Motor 2 40 to drive Prism 37 to rotate self, making the die barrel 22 rotate 180 degrees around Prism 151 to reset. Then, control the rotating ring 5 to continue rotating self to move the die barrel 22 back between the upper and lower pressing plates. Then, open the material conveying pipe 4, and continue to inject carbon powder into the die barrel 22 through the material conveying pipe 4. Repeat S2 - S7 to realize the continuous production of the carbon powder pressed product and further improve the production efficiency of the carbon powder pressed product.

[0081] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
