Description

Technical Field

[0001] The invention belongs to the technical field of graphite forming process equipment, in particular to an isostatic pressing graphite green body forming process. Background Art

[0002] Isostatic graphite is a high-performance graphite material with excellent physical and chemical properties. It is widely used in aerospace, electronics, metallurgy and other fields. With the continuous development of modern industry, the quality and performance requirements of isostatic graphite are getting higher and higher. The isostatic graphite green body forming process is a key link in the isostatic graphite production process, and its process level directly affects the quality of the final product.

[0003] At present, graphite raw materials are crushed and screened to obtain the required particle size range, and then the appropriate ingredient ratio is determined according to the performance requirements of the product and the characteristics of the raw materials. By adding a certain amount of binder and additives, the raw materials, binders and additives are mixed to ensure uniform mixing to achieve the best mixing effect. The screened materials are then loaded into the mold.

[0004] However, when the existing graphite mixing equipment is used, a single circle is used to drive the graphite and the ingredients to be stirred, but the single stirring method easily leads to uneven mixing between the graphite and the ingredients. For materials with high viscosity or easy to agglomerate, it is impossible to stir them apart so that the graphite and the ingredients can be more integrated. However, if the graphite is not stirred evenly, it is easy to cause the graphite to break or break first in the areas with low local strength during subsequent use, affecting the stability and reliability of the overall structure. Summary of the invention

[0005] In order to solve the problem of stirring a single pair of graphite and ingredients proposed in the above background technology, the present invention provides an isostatic pressing graphite green body forming process.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An isostatic graphite green body forming process comprises the following steps:

[0008] S1. Raw material preparation: Select high-quality graphite powder as the main raw material, ensure that the purity of the graphite powder is above 99%, and the particle size distribution is uniform, ensure the density and uniformity of the green body, and add appropriate amounts of auxiliary materials such as binders and lubricants according to product requirements to improve the strength of the green body and improve molding efficiency;

[0015] Preferably, the double-sided gear ring is located on one side of the bottom cover, and a groove matching the slide plate is formed on one side of the bottom cover.

[0016] Preferably, a first sieve plate is movably connected to a side of the table away from the mixing barrel, and a power source device is fixedly connected to a side of the first sieve plate close to the table. At the same time, a first sieve plate is provided on one side of the table. The first sieve plate can finely size-screen the mixed graphite to make full preparations for subsequent processes of the graphite.

[0021] The present invention facilitates the mixing of graphite and ingredients in a more integrated manner through the coordination of structures such as the first motor, the toothed plate, the first bevel gear, and the third bevel gear. The first motor drives the conveyor belt to rotate, and the toothed plate is driven while the conveyor belt rotates, so that the toothed plate can drive the meshing first gear through the groove plate. The rotation of the first gear can bring the rotational force to the first bevel gear and the third bevel gear through the setting of the connecting rod, so that the first bevel gear, the second bevel gear, the third bevel gear, and the fourth bevel gear can rotate forward and reverse, so that the outer ring and inner ring stirring rods on the connecting rod can rotate forward and reverse at the same time in the mixing barrel, which is convenient for better mixing of the graphite and ingredients in the inner and outer rings of the barrel more evenly.

[0022] The present invention facilitates the adjustment of the discharge amount in the mixing barrel through the coordination of the second motor, the double-sided gear rings, the third gear, the slide plate and other structures. After starting the second motor, its powerful power can drive the second gear to rotate rapidly. During the rotation, the second gear will be tightly meshed with the double-sided gear rings, thereby driving the double-sided gear rings to rotate accordingly, and the third gear meshed with the double-sided gear rings will also start to rotate under the drive of the double-sided gear rings. At this time, the third gear further drives the movable tooth plate meshed with it to move. Since the movable tooth plate is fixedly connected to the slide plate, the slide plate can be driven by the movable tooth plate to flexibly adjust the size of the discharge port according to different actual conditions. In this way, the amount of material discharged each time can be controlled more accurately to meet various different production needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 and Figure 7 As shown, an embodiment of the present invention provides an isostatic graphite green body forming process, comprising the following steps:

[0033] S1. Raw material preparation: Select high-quality graphite powder as the main raw material, ensure that the purity of the graphite powder is above 99%, and the particle size distribution is uniform, ensure the density and uniformity of the green body, and add appropriate amounts of auxiliary materials such as binders and lubricants according to product requirements to improve the strength of the green body and improve molding efficiency;

[0034] S2. Mixing and stirring: Put graphite powder and auxiliary materials into a mixing device according to proportion, use a high-speed mixer and a ball mill to mix and stir, and control the stirring time, speed and temperature;

[0035] S3. Mold filling: The mixed materials are loaded into the mold. The shape and size of the mold are designed according to the requirements of the product. After filling, vibration and compaction methods are used to ensure that the material tightly fills the mold to achieve molding.

[0036] like Figures 1 to 7 As shown, an isostatic graphite green body molding device includes a table 1, a mixing barrel 2 is arranged on the upper surface of the table 1, a first motor 3 is arranged on the side of the mixing barrel 2 away from the table 1, an output shaft end of the first motor 3 is rotatably connected to a conveyor belt 4, a side of the conveyor belt 4 close to the mixing barrel 2 is rotatably connected to a toothed plate 5, a side of the toothed plate 5 away from the conveyor belt 4 is meshed with a first gear 7, the first gear 7 is movably connected to a connecting rod 6, a side of the outer ring of the connecting rod 6 away from the first gear 7 is rotatably connected to a first bevel gear 8 and a second bevel gear 81, a side of the first bevel gear 8 is meshed with a third bevel gear 9 and a fourth bevel gear 91, and the first bevel gear An outer ring stirring rod 10 is provided on the side close to the first gear 7, an inner ring stirring rod 11 is provided on the side of the second bevel gear 81 away from the first bevel gear 8, a bottom cover 12 is provided on the side of the mixing barrel 2 close to the table 1, a second motor 13 is provided on the side of the bottom cover 12 close to the table 1, the output shaft end of the second motor 13 is rotatably connected to the second gear 14, one side of the second gear 14 is meshed with a double-sided gear ring 15, the side of the double-sided gear ring 15 away from the second gear 14 is meshed with a third gear 16, one side of the third gear 16 is meshed with a movable tooth plate 17, and the side of the movable tooth plate 17 close to the bottom cover 12 is movably connected to a slide plate 18.

[0037] The first motor 3 is provided to drive the conveyor belt 4 to rotate, and the conveyor belt 4 drives the tooth plate 5 while rotating, so that the tooth plate 5 can drive the meshing first gear 7 through the groove plate 61, and the rotation of the first gear 7 can bring the rotational force to the first bevel gear 8 and the third bevel gear 9 through the setting of the connecting rod 6, so that the first bevel gear 8, the second bevel gear 81, the third bevel gear 9, and the fourth bevel gear 91 can rotate forward and reverse, so that the outer ring and the inner ring stirring rod 11 on the connecting rod 6 can rotate forward and reverse at the same time in the mixing barrel 2, so as to better mix the graphite and ingredients in the inner and outer rings of the barrel more evenly.

[0038] After starting the second motor 13, its powerful power can drive the second gear 14 to rotate rapidly. During the rotation, the second gear 14 will be tightly meshed with the bilateral gear rings 15, thereby driving the bilateral gear rings 15 to rotate accordingly, and the third gear 16 meshed with the bilateral gear rings 15 will also start to rotate driven by the bilateral gear rings 15. At this time, the third gear 16 further drives the movable tooth plate 17 meshed with it to move. Since the movable tooth plate 17 is fixedly connected to the slide plate 18, the slide plate 18 can be driven by the movable tooth plate 17 to flexibly adjust the size of the discharge port according to different actual conditions. In this way, the amount of material discharged each time can be controlled more accurately to meet various production needs.

[0039] like Figure 1 , Figure 4 , Figure 6 As shown, a stabilizing frame 110 is fixedly connected to one side of the table 1 close to the mixing barrel 2. The stabilizing frame 110 is in the shape of two semicircles. The inner diameter of the stabilizing frame 110 fits the outer diameter of the mixing barrel 2. The outer ring of the connecting rod 6 is provided with a groove plate 61 adapted to the tooth plate 5. The first bevel gear 8 and the second bevel gear 81 are vertically opposed to each other, and the third bevel gear 9 and the fourth bevel gear 91 are horizontally opposed to each other. The number of slide plates 18 is set to be multiple, and the shape of the slide plate 18 is triangular. The shape combination of multiple slide plates 18 presents a circle.

[0040] The above scheme is adopted: the mixing barrel 2 can be fixed by the stabilizing frame 110 arranged on the table 1 to prevent the mixing barrel 2 from being unstable on the table 1. The stabilizing frame 110 is in the shape of two semicircles. The semicircular shape can better fit the mixing barrel 2. The outer ring of the connecting rod 6 is provided with a groove plate 61. The arrangement of the groove plate 61 facilitates the toothed plate 5 to drive the first gear 7 to rotate within the movement trajectory of the groove plate 61. The groove plate 61 can play a limiting role. The first bevel gear 8 is opposite to the second bevel gear 81, and is meshed with the third bevel gear 9 and the fourth bevel gear 91, so that the bevel gears can rotate forward and reverse, thereby driving the stirring rods of the outer and inner rings to stir. The number of slide plates 18 is set to multiple, and the multiple triangles are combined in a circular shape, so that when the graphite is stirred and mixed, the bottom cover 12 will not leak material, and the circle can be in a closed state to close the bottom cover 12.

[0041] like Figure 1 , Figure 6 As shown, the double-sided gear ring 15 is located on one side of the bottom cover 12, a groove compatible with the slide plate 18 is opened on one side of the bottom cover 12, a first sieve plate 19 is movably connected to the side of the table 1 away from the mixing barrel 2, a power source device 20 is fixedly connected to the side of the first sieve plate 19 close to the table 1, a connecting rod 22 is movably connected to one side of the power source device 20, and a second sieve plate 21 is arranged on the side of the connecting rod 22 away from the power source device 20.

[0042] The above scheme is adopted: a groove adapted to the slide plate 18 is provided on one side of the bottom cover 12, so that the slide plate 18 can move smoothly on the bottom cover 12, ensuring the accuracy and stability of the size adjustment of the discharge port. At the same time, a first sieve plate 19 is provided on one side of the table 1. The first sieve plate 19 can finely size-screen the mixed graphite, making full preparations for the subsequent process of the graphite. After screening by the first sieve plate 19, the situation of too large difference in graphite particle size can be effectively avoided, thereby preventing the uneven particle size from causing the problem of the size difference of the graphite particles. And it affects the smooth progress of subsequent graphite processing steps. Moreover, the power source device 20 arranged on the first screen plate 19 can provide powerful power support for the operation of the connecting rod 22, so that the connecting rod 22 can drive the second screen plate 21 on one side to work together. Under the joint action of the two screen plates, the graphite can be better screened, which greatly improves the screening effect. The design of double screen plates not only improves the screening accuracy and efficiency, but also provides better raw materials for the subsequent processing of graphite, laying a solid foundation for the production of high-quality graphite products.

[0043] like Figure 1 , Figure 7As shown, the second sieve plate 21 is connected to the first sieve plate 19 via a spring 23, a molding frame 24 is provided on the side of the second sieve plate 21 away from the first sieve plate 19, the first sieve plate 19 is connected to the table 1 via a connecting block 111, the first sieve plate 19 is connected to the connecting block 111 via a rotating shaft, an inclined plate 311 is provided on one side of the conveyor belt 4, and the connecting rod 6 is rotatably connected to the inclined plate 311.

[0044] The above scheme is adopted: the second sieve plate 21 is connected to the first sieve plate 19 through the spring 23, and the spring 23 plays an important buffering role in the movement of the two sieve plates. When the power source device 20 drives the connecting rod 22 to move the two sieve plates, the spring 23 can effectively absorb and alleviate the impact force generated by the movement of the sieve plates, avoiding the two sieve plates from shaking too stiffly. If there is no buffering of the spring 23, the two sieve plates are likely to shake the graphite out of the range of the sieve plates when shaking violently, causing waste of materials and chaos in the production environment. The first sieve plate 19 is connected to the table 1 through the connecting block 111. This connection method can better achieve a stabilizing effect and avoid the instability of the sieve plate during operation. The inclined plate 311 set on one side of the conveyor belt 4 can also achieve a stabilizing connection effect, so that the inclined plate 311 and the connecting rod 6 can be better connected.

[0045] The working principle and use process of the present invention:

[0046] First, slowly pour the graphite into the mixing barrel 2, and then accurately pour the required mixed ingredients according to specific needs, and then start the first motor 3. At this time, the first motor 3 starts to run, which can effectively drive the conveyor belt 4 to rotate. The rotation of the conveyor belt 4 will further drive the tooth plate 5, so that the tooth plate 5 can interact with the meshing first gear 7. Under this action, the first gear 7 drives the first bevel gear 8 and the second bevel gear 81 through the setting of the connecting rod 6. Since the first bevel gear 8 is meshed with the third bevel gear 9 and the fourth bevel gear 91, when the first bevel gear 8 and the second bevel gear 81 rotate, the outer ring stirring rod 10 and the inner ring stirring rod 11 on the connecting rod 6 can rotate efficiently under the forward and reverse rotation of the bevel gears, so as to fully stir the graphite in the mixing barrel 2 in all directions and without dead ends. After careful stirring, the graphite and the ingredients are evenly mixed, which lays a solid foundation for subsequent processing procedures. Then, start the second motor 13. After the second motor 13 starts working, The second gear 14 can be driven to rotate rapidly, and the rotation of the second gear 14 can drive the meshing bilateral gear ring 15, so that the bilateral gear ring 15 drives the meshing third gear 16 while rotating, and the third gear 16 rotates and then drives the meshing movable tooth plate 17. Since the movable tooth plate 17 is fixedly connected to the slide plate 18, the slide plate 18 can move smoothly on the bottom cover 12. In this way, the graphite discharge amount in the mixing barrel 2 can be accurately controlled according to different production needs to meet the requirements of various production scenarios. The mixed graphite will come to the first sieve plate 19 and the second sieve plate 21, and the connecting rod 22 is driven by the power source device 20, and the connecting rod 22 further drives the sieve plate to move. The two sieve plates cooperate with each other to perform fine screening of the graphite. This screening can effectively remove particles that do not meet the requirements, ensure the quality and performance of subsequent graphite during use, and the screened graphite is more in line with the requirements of subsequent processing procedures, providing reliable guarantee for the production of high-quality graphite products.
