Description

Technical Field

[0001] This invention relates to the field of graphite product manufacturing technology, specifically to a graphite material shaping device and its preparation process that facilitates coloring. Background Technology

[0002] Graphite materials possess excellent high-temperature resistance, plasticity, and chemical stability. Based on these advantages, many handicrafts are now made from graphite raw materials. However, the production of graphite handicrafts often requires surface coloring. Graphite has a relatively smooth surface and good lubricity, so direct coloring often yields poor results and weak surface adhesion. Some existing equipment requires the addition of fluoride salts to the graphite raw materials during the production of graphite handicrafts. During high-temperature carbonization, the fluoride salts decompose, forming pits on the graphite surface to increase its roughness and facilitate coloring. However, this method increases production costs and is cumbersome and time-consuming due to the high-temperature carbonization process. Therefore, this invention provides a graphite material shaping device that facilitates coloring. Summary of the Invention

[0003] The purpose of this invention is to provide a graphite material shaping device that is easy to color. Softened graphite raw material is injected into the shaping component. The hole-forming component extends into the shaping component under the guidance and limiting of the guide component. The roller pressing component rolls and compacts the graphite raw material in the shaping component. The roller pressing component, together with the shaping component and the hole-forming component, presses the graphite raw material into a graphite ring with holes on the surface. The guide component guides and drives the hole-forming component to detach from the shaping component. Through the cooperation of the above components, the initial shaping of the graphite craft and the roughening of the pits on the outer surface are cleverly achieved. The mechanical linkage process reduces the production cost and is simple and efficient to operate.

[0004] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0005] A graphite material shaping device that is easy to color includes a rotating base and a first drive motor mounted on the rotating base. The output end of the first drive motor is fixedly connected to a shaping component and a hole-forming component that cooperates with the shaping component. A guide component that fits into the outer ring rotation path of the hole-forming component is also provided. A roller pressing component that cooperates with the shaping component is also provided on one side of the shaping component. The shaping component performs compaction and hole-forming treatment on the graphite raw material under the simultaneous action of the roller pressing component and the hole-forming component. The guide component drives the hole-forming component to detach from the shaping component after the compaction and hole-forming are completed.

[0006] The shaping component includes a base fixedly connected to the output end of the first drive motor. A shaping mold is fixedly provided on the outer side of the base.

[0007] The hole-forming assembly includes several sliding grooves arranged in a circumferential array on the base. An arc-shaped pressure plate is slidably disposed in the sliding groove. A return spring is connected between the tail end of the arc-shaped pressure plate and the inner wall of the sliding groove. A dot-hole pin matching the first through hole is opened on the inner wall of the arc-shaped pressure plate. An arc-shaped top pressure block is disposed on the outer wall of the arc-shaped pressure plate.

[0008] As a preferred embodiment, the diameter of the dotting needle is 0.4 mm to 0.6 mm, and the diameter of the first through hole matches the diameter of the dotting needle.

[0009] As a preferred embodiment, the diameter of the shaping mold is 140mm, the diameter of the limiting cover plate is 150mm, the diameter of the second through hole is 45mm, and the center distance between the second through hole and the limiting cover plate is 42mm.

[0011] As a preferred embodiment, the guide ring has a first pin hole and a second pin hole, and the extension rod has a locking hole that matches the first pin hole and the second pin hole.

[0012] As a preferred embodiment, the roller pressing assembly includes a support base and a first cylinder mounted on the support base. The first cylinder is used to drive a second drive motor. A linear slider is connected to the bottom of the second drive motor. A linear slide rail matching the linear slider is provided on the support base. A roller pressing cylinder is fixedly connected to the output end of the second drive motor. A second cylinder is also provided below the support base. The second cylinder is used to push the support base to move up and down in the vertical direction.

[0013] As a preferred embodiment, the lifting stroke of the second cylinder is 4mm.

[0014] As another preferred embodiment, a flipping assembly is also provided on one side of the rotating seat. The flipping assembly includes a third cylinder and a rack pushed by the third cylinder. A gear that meshes with the rack is fixedly connected to the outer end of the rotating shaft of the rotating seat.

[0015] Another objective of this invention is to provide a process for preparing easily colored graphite materials, the technical solution of which is as follows:

[0016] Step 1, graphite batching process: petroleum coke and pitch coke are mixed as graphite raw materials. During the mixing process, a binder is added, which can be coal tar pitch, petroleum pitch or resin.

[0017] Step 2, graphite feeding process: The graphite raw material after mixing and bonding in Step 1 is fed into the shaping mold through the feeding interface;

[0018] Step 3, one-time forming process: the roller cylinder in the roller pressing assembly extends horizontally into the forming mold, and the roller pressing cylinder and the forming mold rotate synchronously to perform the first roller pressing forming of the graphite raw material in Step 2. The graphite wall thickness of the first roller pressing forming is 8mm.

[0019] Step 4, secondary forming process: The roller cylinder in step 3 descends vertically under the drive of cylinder No. 2. The roller cylinder performs a second roller forming on the graphite after the first roller forming. The graphite wall thickness after the second roller forming is 6mm.

[0020] Step 5, three-stage forming process: the roller in step 4 continues to descend vertically under the drive of cylinder No. 2. The roller performs a third roller forming on the graphite after the second roller forming. The graphite wall thickness after the third roller forming is 4mm.

[0021] Step six, guiding the demolding process: After the graphite is rolled three times in step five, the rolling cylinder is reset and detached from the shaping mold. The guiding component drives the hole forming component to detach from the shaping component after the three rolling processes are completed.

[0022] Step 7, the filling and turning process: the shaping mold mentioned in step 6 is rotated 90 degrees by the turning component. The graphite raw material in step 1 continues to be injected into the center of the shaping mold through the feeding interface to fill and compact the graphite after three roll forming. After the filling is completed, the graphite raw material in the center of the shaping mold is pressed and compacted.

[0023] Step 8, graphite calcination process: The compacted graphite column in step 7 is calcined. The calcination temperature range is 900℃ to 1000℃, the heating rate is 2℃ / hour to 4℃ / hour, and the temperature difference in the furnace is 60℃ to 90℃.

[0024] As a preferred option, the pressure for top compaction in step seven is 10 MPa to 15 MPa.

[0025] The beneficial effects of this invention are:

[0026] 1. The roller pressing assembly of the present invention performs shaping and compaction treatment on the graphite raw materials injected inside and outside the shaping assembly to complete the initial shaping of the outer ring. At the same time, the dotting needles on the hole forming assembly, guided by the guiding assembly, pass through the shaping assembly in an inward contraction manner to perform dotting treatment on the graphite surface to form pits. Through the cooperation of the above-mentioned components, the initial shaping of the graphite craft and the roughening treatment of the pits on the outer surface are cleverly achieved, solving the problems of easy fading and peeling of the color on the surface of the graphite craft. The mechanical linkage reduces the production cost and is simple and efficient to operate.

[0027] 2. In this invention, the shaping component and the hole-forming component are horizontally positioned during operation. The hole-forming component extends pre-into the shaping component and works with the rolling component to roll the input graphite raw material circumferentially. The advantage of this horizontal positioning is that the rolling component ensures uniform compactness of the graphite raw material outside the hole during rolling, resulting in stable structural strength. If vertical downward or upward pressing is used (e.g....), the results are significantly improved. Figure 12 As shown), the graphite at the top of the hole will be pressed very tightly (as shown). Figure 13 As shown at point a), the graphite at the bottom of the hole becomes very loose (as shown in Figure a). Figure 13 As shown at point b), this results in inconsistent internal density of the graphite product, affecting its structural strength.

[0028] 3. The present invention has a first pin hole and a second pin hole on the guide ring, and a corresponding locking hole on the extension rod. When the operator rotates the guide ring to control the hole forming assembly, the pins can be inserted between the pin holes and the locking holes to lock the corresponding position of the guide ring. This design makes it easier to change the position of the guide ring and the locking effect is stable.

[0029] In summary, this easy-to-color graphite material shaping device has the advantages of ingenious design, simple structure, and efficient and stable use, and is especially suitable for the field of graphite product manufacturing technology. Attached Figure Description

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figures 1 to 13As shown, this embodiment of the invention provides a graphite material shaping device that is easy to color, including a rotating base 1 and a first drive motor 11 mounted on the rotating base 1. The output end of the first drive motor 11 is fixedly connected to a shaping component 2 and a hole-forming component 3 that cooperates with the shaping component 2. A guide component 4 that fits into the outer ring rotation path of the hole-forming component 3 is also provided. A roller pressing component 5 that cooperates with the shaping component 2 is also provided on one side. The shaping component 2 performs compaction and hole-forming treatment on the graphite raw material under the simultaneous action of the roller pressing component 5 and the hole-forming component 3. The guide component 4 drives the hole-forming component 3 to detach from the shaping component 2 after the compaction and hole-forming are completed.

[0048] The shaping component 2 includes a base 21 fixedly connected to the output end of the first drive motor 11. A shaping mold 22 is fixedly provided on the outer side of the base 21. The shaping mold 22 has several first through holes 23 along the circumferential direction. A limit cover plate 24 is rotatably provided at the outer end of the shaping mold 22. A material conveying interface 25 is provided at the center of the limit cover plate 24. A second through hole 26 is also provided on the limit cover plate 24.

[0049] The hole forming assembly 3 includes several grooves 31 arranged in a circular array on the base 21. An arc-shaped pressure plate 32 is slidably arranged in the groove 31. A return spring 33 is connected between the tail end of the arc-shaped pressure plate 32 and the inner wall of the groove 31. A dot pin 34 matching the first through hole 23 is opened on the inner wall of the arc-shaped pressure plate 32. An arc-shaped top pressure block 35 is arranged on the outer wall of the arc-shaped pressure plate 32.

[0050] In operation, the operator controls the guide component 4 to rotate, causing the hole-forming component 3 to extend into the shaping mold 22. Softened graphite raw material is injected into the shaping mold 22 through the feeding interface 25. The first drive motor 11 drives the shaping component 2 to rotate circumferentially, while the rolling component 5 enters the shaping mold 22 through the second through hole 26 to perform circumferential rolling (e.g., ...). Figure 9 As shown), the roller pressing assembly 5 gradually moves downwards in the vertical direction and compacts and shapes the graphite raw material in the shaping mold 22, pressing it into a uniformly thick ring shape. After the roller pressing is completed, the roller pressing assembly 5 resets and exits. The operator then guides the hole forming assembly 3 to reset and detach it from the shaping mold 22 by rotating the guide assembly 4 in the opposite direction. Thus, the graphite preliminary product with hole forming can be demolded in the shaping mold 22 (e.g., ...). Figure 10 (As shown in state A).

[0051] Here, the dotting needles 34 on the hole-forming component 3 of the present invention pass through the shaping component 2 by inward contraction under the guidance of the guiding component 4. The roller pressing component 5 performs shaping and compaction treatment on the graphite raw materials injected inside and outside the shaping component 2 to complete the initial production of the outer ring. At the same time, the dotting and pitting treatment on the graphite surface is completed by the inserted hole-forming component 3. Through the cooperation of the above components, the initial shaping of the graphite craft and the dotting and pitting treatment on the outer surface are cleverly achieved, solving the problems of easy fading and peeling of the color on the surface of the graphite craft. The mechanical linkage and cooperation process reduces the production cost and is simple and efficient to operate.

[0052] See attached document Figure 2 and attached Figure 3 Specifically, the diameter of the pin 34 is 0.4 mm to 0.6 mm, and the diameter of the through hole 23 matches the diameter of the pin 34.

[0053] See attached document Figure 2 Specifically, the diameter of the shaping mold 22 is 140mm, the diameter of the limiting cover plate 24 is 150mm, the diameter of the second through hole 26 is 45mm, and the center distance between the second through hole 26 and the limiting cover plate 24 is 42mm.

[0054] See attached document Figure 2 To be continued Figure 4 Specifically, the guide assembly 4 includes an extension rod 41 disposed at the outer end of the base 21. A limit block 42 is disposed at the bottom end of the extension rod 41. A matching guide ring 43 is disposed on the outer side of the arc-shaped pressure plate 32. A sliding limit groove 44 that matches the limit block 42 is opened on the outer end face of the guide ring 43. A second arc-shaped pressure block 45 that matches the first arc-shaped pressure block 35 is disposed on the inner wall surface of the guide ring 43. The limit block 42 achieves limited and fixed sliding by being embedded in the sliding limit groove 44. When the guide ring 43 rotates, the second arc-shaped pressure block 45 rotates to the position of the first arc-shaped pressure block 35, causing the arc-shaped pressure plate 32 to retract and enter the shaping mold 22.

[0055] See attached document Figure 2 To be continued Figure 4 Specifically, the guide ring 43 has a first pin hole 46 and a second pin hole 47, and the extension rod 41 has a locking hole 48 that matches the first pin hole 46 and the second pin hole 47. The pin can be inserted into the first pin hole 46 or the second pin hole 47 through the locking hole 48 to achieve locking and fixation in two directions.

[0056] It should be noted that the guide ring 43 of the present invention has a first pin hole 46 and a second pin hole 47, and the extension rod 41 has a corresponding locking hole 48. When the operator rotates the guide ring 43 to control the hole forming assembly 3, the pins can be inserted between each pin hole and the locking hole 48 to lock the corresponding position of the guide ring 43. This design makes it easier to change the position of the guide ring 43 and the locking effect is stable.

[0057] See attached document Figure 5 and attached Figure 9 Specifically, the roller pressing assembly 5 includes a support base 51 and a first cylinder 52 mounted on the support base 51. The first cylinder 52 drives a second drive motor 53. A linear slider 54 is connected to the bottom of the second drive motor 53. A linear slide rail 55 matching the linear slider 54 is mounted on the support base 51. A roller pressing cylinder 56 is fixedly connected to the output end of the second drive motor 53. The roller pressing cylinder 56 is concentrically positioned with the second through hole 26. A second cylinder 57 is also mounted below the support base. The second cylinder 57 drives the support base to move vertically up and down. The second drive motor 53 drives the roller pressing cylinder 56 to rotate during operation. The roller pressing cylinder 56 enters the shaping mold 22 through the second through hole 26 for compaction and shaping. The second cylinder drives the roller pressing cylinder to descend vertically. (See attached diagram) Figure 9 As shown, the distance L between the center of the roller cylinder and the inner wall of the graphite gradually decreases, and the inner wall of the graphite is pressed more firmly and tightly as the roller cylinder gradually descends.

[0058] See attached document Figure 9 Specifically, the lifting stroke of cylinder 57 is 4mm. Figure 9 The reduction in the distance between L and L is 4 mm.

[0059] It is worth mentioning that the shaping component 2 and the hole-forming component 3 of this invention are set horizontally. The hole-forming component 3 is pre-extended into the shaping component 2 to cooperate with the rolling component 5 to roll the input graphite raw material in the circumferential direction. The advantage of the horizontal setting is that the rolling component 5 ensures that the compactness of the graphite raw material outside the hole is consistent during the rolling process, resulting in stable structural strength. If vertical downward and upward pressing is used (e.g.) Figure 12 As shown), the graphite at the top of the hole will be pressed very tightly (as shown). Figure 13 As shown at point a), the graphite at the bottom of the hole becomes very loose (as shown in Figure a). Figure 13 As shown at point b), this results in inconsistent internal density of the graphite product, affecting its structural strength.

[0060] Example 2

[0061] As attached Figure 6As shown, the components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that a flipping assembly 6 is also provided on one side of the rotating seat 1. The flipping assembly 6 includes a third cylinder 61 and a rack 62 pushed by the third cylinder 61. A gear 63 that meshes with the rack 62 is fixedly connected to the outer end of the rotating shaft of the rotating seat 1. The third cylinder 61 pushes the rack 62 to drive the gear 63 to rotate. The rotation of the gear 63 drives the rotating seat 1 to perform a 90-degree reciprocating flip. After the graphite initial shaping point hole in the shaping assembly 2 is completed, the rotating seat 1 is flipped to face upwards. Then, graphite raw materials are continued to be injected through the feeding interface 25 to complete the subsequent shaping and filling. After the shaping and filling is completed, the graphite product is taken out and then subjected to subsequent compaction treatment (such as...). Figure 11 (as shown in state B).

[0066] Step 3, one-time forming process: the roller cylinder 56 in the roller pressing assembly 5 extends horizontally into the shaping mold 22. The roller cylinder 56 and the shaping mold 22 rotate synchronously to perform the first roller pressing forming of the graphite raw material in Step 2. The graphite wall thickness of the first roller pressing forming is 8mm.

[0067] Step 4, secondary forming process: The roller cylinder 56 in step 3 descends vertically under the drive of cylinder 57. The roller cylinder 56 performs a second roller forming on the graphite after the first roller forming. The graphite wall thickness after the second roller forming is 6mm.

[0069] Step six, guiding the demolding process: After the graphite is rolled three times in step five, the rolling cylinder 56 is reset and detached from the shaping mold 22. The guiding component 4 drives the hole forming component 3 to detach from the shaping component 2 after the three rolling processes are completed.

[0070] Step 7, the filling and turning process: The shaping mold 22 mentioned in step 6 is rotated 90 degrees under the drive of the turning component 6. The graphite raw material in step 1 continues to be injected into the center of the shaping mold 22 through the feeding interface 25 to fill and compact the graphite after three roll forming. After the filling is completed, the graphite raw material in the center of the shaping mold 22 is pressed and compacted.

[0071] Step 8, graphite calcination process: The compacted graphite column in step 7 is calcined. The calcination temperature range is 900℃ to 1000℃, the heating rate is 2℃ / hour to 4℃ / hour, and the temperature difference in the furnace is 60℃ to 90℃.
