TECHNICAL FIELD
[0001] The application relates to the technical field of ceramic insulator production, and particularly relates to a green body shaping device for ceramic insulator production. BACKGROUND
[0002] In the modern electric power industry, ceramic insulators are key components for ensuring the safe and stable operation of electric power systems, and are widely used in overhead transmission lines, substations and other facilities, playing an important role in isolating live parts from non-live parts and preventing current leakage. The performance of the ceramic insulators is directly related to the stability and safety of power transmission. Double-disc suspension porcelain insulators belong to a type of ceramic insulators. In the production process of double-disc suspension porcelain insulators, the green body shaping and repairing process is a key link for determining the dimensional accuracy and production efficiency of the products. Due to the double-umbrella skirt structure, the coaxiality of the internal cavity and the profile accuracy of the external umbrella skirt need to be ensured at the same time to meet the requirements of pollution flashover resistance and mechanical bearing in high-voltage transmission scenarios.

Detailed Implementation
[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0044] like Figures 1 to 14As shown, a clay blank shaping device for ceramic insulator production according to the present invention includes a processing table 10, a rotating storage cylinder 11, an internal tool holder mounting platform 20, an internal trimming tool assembly, a drive and reset assembly, a support platform structure, and an external trimming tool assembly. A bearing 12 is fixedly installed in the middle of one side of the processing table 10. The rotating storage cylinder 11 is installed on the inner wall of the bearing 12, and the length of the rotating storage cylinder 11 is greater than the thickness of the bearing 12. The rotating storage cylinder 11 is coaxially arranged with the internal tool holder mounting platform 20. The inner diameter of the rotating storage cylinder 11 is larger than the diameter of the internal tool holder mounting platform 20 to avoid interference between the rotating storage cylinder 11 and the internal tool holder mounting platform 20 during rotation, ensuring smooth rotation of the rotating storage cylinder 11. Furthermore, the upper surface of the internal tool holder mounting platform 20 and the upper surface of the rotating storage cylinder 11 are on the same horizontal plane to ensure better subsequent shaping and finishing of the inner wall of the clay blank. Multiple sets of internal trimming tool assemblies are slidably mounted on the internal tool holder mounting platform 20, and these multiple sets of internal trimming tool assemblies are distributed in a circumferential array. An internal trimming knife assembly is mounted on an internal tool holder mounting table 20 and moves along the axis of the internal tool holder mounting table 20. The internal trimming knife assembly is used to trim and shape the inner wall of the clay blank. A drive reset assembly is mounted on the internal tool holder mounting table 20 and is used to move multiple internal trimming knife assemblies simultaneously along the axis of the internal tool holder mounting table 20, so that multiple internal trimming knife assemblies can work together to trim and shape the inner wall of the clay blank, thereby improving trimming efficiency. A drilling structure is connected to the drive reset assembly and is used to drill holes in the top of the inner wall of the clay blank. A support platform structure is set above the internal tool holder mounting table 20 and is connected to the internal trimming knife assembly. The support platform structure is used to support the top of the inner wall of the clay blank. An external trimming knife assembly is set on the processing table 10 and is used to trim and shape the outside of the clay blank. The external trimming knife assembly and the internal trimming knife assembly work together to trim and shape both the outside and the inner wall of the clay blank simultaneously.
[0045] After pressing the clay blank, it is placed upside down on the support structure. At this time, the top of the inner wall of the clay blank overlaps the support structure, and the bottom of the clay blank overlaps the rotating storage cylinder 11. The maximum diameter of the inner wall of the clay blank is smaller than the inner diameter of the rotating storage cylinder 11, so that the part of the inner wall of the clay blank that needs to be trimmed and shaped is suspended in the air. The structural diagram after installing the clay blank is shown below. Figure 3 and Figure 4As shown, the rotating storage cylinder 11 can then be rotated, and the clay blank rotates accordingly. At the same time, the drive reset assembly moves multiple internal trimming knife assemblies toward the inner wall of the clay blank. As the internal trimming knife assemblies move and come into contact with the inner wall of the clay blank, the inner wall of the clay blank is trimmed. While the internal trimming knife assemblies are trimming the inner wall of the clay blank, the external trimming knife assemblies are trimming the outer side of the clay blank. Simultaneously, the drilling structure drills holes in the top of the inner wall of the clay blank. This allows the trimming of the inner and outer sides of the clay blank and the drilling of the inner side of the clay blank to be performed simultaneously, thereby reducing the steps of trimming and shaping the clay blank and improving the efficiency of trimming and shaping the clay blank.
[0046] like Figure 6 and Figure 7 The support platform structure includes a support frustum 30 coaxially arranged with the internal tool holder mounting platform 20. A circular groove is provided on the top side of the support frustum 30. A rotating platform 31 is rotatably arranged on the inner wall of the circular groove. The upper surface of the rotating platform 31 is on the same plane as the upper surface of the support frustum 30. A connecting hole 311 is provided at the center of both the rotating platform 31 and the support frustum 30. A plurality of storage slots 301 are provided on the outer surface of the support frustum 30.
[0047] After the clay blank is placed, the top of the inner wall of the clay blank comes into contact with the rotating platform 31, and there is a gap between the inner wall of the clay blank and the internal trimming knife assembly. As the rotating storage cylinder 11 drives the clay blank to rotate, the rotating platform 31 rotates accordingly. The rotating platform 31 increases the contact area with the clay blank. The rotating platform 31 and the rotating storage cylinder 11 enable the clay blank to rotate stably during the trimming process. The upper surface of the supporting frustum 30 is a smooth surface, which reduces the friction between the clay blank and the support frustum, allowing the clay blank to rotate smoothly.
[0048] like Figure 6 , Figure 7 and Figure 12 The internal trimming tool assembly includes an arc-shaped tool holder 40 disposed between the internal tool holder mounting platform 20 and the supporting frustum 30. Limiting sliders 41 are connected to both the top and bottom of the arc-shaped tool holder 40, and reinforcing ribs or plates are provided between the arc-shaped tool holder 40 and the limiting sliders 41 to ensure the stability of the connection between them. An internal trimming tool 42 is connected to the outer surface of the arc-shaped tool holder 40, and a top trimming tool 43 is connected to the top of the internal trimming tool 42. The length of the top trimming tool 43 is the same as the thickness of the supporting frustum 30. The top trimming tool 43 is located inside the receiving groove 301. Limiting grooves 201 are provided on one side of both the internal tool holder mounting platform 20 and the supporting frustum 30. The limiting sliders 41 and the limiting grooves 201 are both T-shaped or dovetail-shaped. The top of the arc-shaped tool holder 40 contacts the bottom of the supporting frustum 30, and the bottom of the arc-shaped tool holder 40 contacts the top of the internal tool holder mounting platform 20.
[0049] During the shaping and finishing of the inner wall of the clay blank, the limiting slider 41 is moved out of the limiting groove 201 by driving the reset component. At this time, the inner trimming knife 42 drives the top trimming knife 43 to gradually move towards the inner wall of the clay blank, so that the inner trimming knife 42 gradually contacts the inner wall of the clay blank and performs scraping and trimming operations. During this process, the top trimming knife 43 also gradually contacts the inner wall of the clay blank and performs scraping and trimming operations. Through the joint cooperation of the top trimming knife 43 and the inner trimming knife 42, the interior of the clay blank can be bowl-shaped after trimming. By drilling a hole at the top of the inner wall of the clay blank through the drilling structure, a hole can be formed in the middle of the inner cavity of the clay blank after trimming, thus forming the final shape of the disc-shaped suspension porcelain insulator.
[0050] When the internal trimming knife 42 moves towards the inner wall of the clay blank for trimming, the limiting slider 41, the limiting groove 201 and the arc-shaped knife holder 40 can ensure the connection stability between the internal knife holder mounting platform 20 and the supporting frustum 30, so that the distance between the internal knife holder mounting platform 20 and the supporting frustum 30 is constant. In addition, the length of the limiting slider 41 is greater than the distance the arc-shaped knife holder 40 moves, thereby avoiding the separation of the limiting slider 41 and the limiting groove 201 during the trimming process of the inside of the clay blank.
[0051] like Figures 5-11 The drive reset assembly includes a support frame 21 mounted on the internal tool post mounting table 20. A dual-axis motor 22 is mounted in the middle of the support frame 21. One output end of the dual-axis motor 22 is connected to a turntable 23, and the other output end of the dual-axis motor 22 is connected to a drilling structure. The turntable 23 is coaxial with the internal tool post mounting table 20. Multiple arc-shaped bogies 24 are fixedly connected to the outer surface of the turntable 23. A connecting slide rod 25 is slidably arranged on the inner wall of each arc-shaped bogie 24, and a push slider 26 is connected to the bottom end of each connecting slide rod 25. The push slider 26 is located inside the limiting slide groove 201 opened in the internal tool holder mounting platform 20 and is slidably connected to the limiting slide groove 201. The push slider 26 corresponds one-to-one with the limiting slide groove 201. Each push slider 26 has a through hole 261 on one side. Each through hole 261 is provided with a return spring 27. One end of the return spring 27 is connected to the inner wall of the limiting slide groove 201 opened in the internal tool holder mounting platform 20, and the other end of the return spring 27 is connected to the limiting slider 41 located on the internal tool holder mounting platform 20.
[0052] When it is necessary to trim and shape the inside of the clay blank, the dual-axis motor 22 is started, and the turntable 23 will drive multiple arc-shaped bogies 24 to rotate. Because the push slider 26 is slidably connected to the limiting slide groove 201, and the connecting slide rod 25 is slidably connected to the inner wall of the arc-shaped bogie 24, as the arc-shaped bogie 24 rotates, the connecting slide rod 25 drives the push slider 26 to move, and the push slider 26 contacts the limiting slider 41 and pushes the limiting slider 41 out of the limiting slide groove 201. This allows the arc-shaped cutter holder 40 to drive the internal trimming cutter 42 and the top trimming cutter 43 to trim the inside of the clay blank. At this time, the return spring 27 is in a stretched state. After completion, the dual-axis motor 22 is rotated in the opposite direction. At this time, the turntable 23 drives multiple arc-shaped bogies 24 to rotate, thereby resetting the push slider 26. Under the reaction force of the reset spring 27, the limit slider 41 will drive the arc-shaped tool holder 40 to reset, completing the trimming operation on the inner wall of the clay blank. The clay material generated during the trimming process will fall from the gap between the internal tool holder mounting platform 20 and the rotating storage cylinder 11 into the interior of the processing table 10, thereby achieving the purpose of automatically discharging the clay material during the trimming process on the inner wall of the clay blank. By setting the drive reset component, multiple internal trimming tools 42 can be driven to move simultaneously, and the speed of trimming the interior of the clay blank can be accelerated by using multiple internal trimming tools 42.
[0053] It should be noted that the return spring 27 passes through the inside of the through hole 261, and the outer diameter of the return spring 27 is smaller than the diameter of the through hole 261. This ensures that the push slider 26 will not interfere with the return spring 27 during the movement, thus ensuring that the push slider 26 moves smoothly.
[0054] like Figure 9 and Figure 11 The drilling structure includes a lead screw 50 connected to one output end of a dual-axis motor 22. A nut 51 is threaded onto the outer surface of the lead screw 50. A sleeve 52 is fixedly connected to one side of the nut 51. A scraper 53 is connected to the top of the sleeve 52. A guide rod 54 is fixedly connected to one side of the sleeve 52. The guide rod 54 passes through the support frame 21 and is slidably connected to the support frame 21.
[0055] The sleeve 52 is coaxial with the connecting hole 311. A part of the sleeve 52 is located inside the connecting hole 311, and the outer diameter of the sleeve 52 is smaller than the diameter of the connecting hole 311. This prevents the sleeve 52 from interfering with the rotating table 31 and the supporting frustum 30 during movement. The mud scraped by the scraper 53 can fall down through the gap between the sleeve 52 and the connecting hole 311. A part of the lead screw 50 is located inside the sleeve 52, and the inner diameter of the sleeve 52 is larger than the outer diameter of the lead screw 50. This prevents the lead screw 50 from interfering with the sleeve 52 during rotation, ensuring that the lead screw 50 rotates smoothly.
[0056] During the blank trimming process, the dual-axis motor 22 drives the lead screw 50 to rotate. Under the guidance of the guide rod 54, the nut 51 drives the sleeve 52 to move upward, thereby causing the scraper 53 to move upward and contact the top of the inner wall of the blank. As the blank rotates and the scraper 53 moves upward, the blank is drilled. The mud material generated during the drilling process falls downward from the gap between the sleeve 52 and the connecting hole 311, which facilitates the discharge of the mud material.
[0057] It should be noted that the pitch of the lead screw 50 is determined according to the required drilling depth, so that when the internal trimming cutter 42 moves to the end of its stroke, the travel of the scraper 53 is the required drilling depth.
[0058] like Figures 1-4 and Figure 14 The external trimming tool assembly includes a bracket 13 mounted on the top side of the processing table 10. A rotating shaft 14 is rotatably connected to one side of the bracket 13. The bottom end of the rotating shaft 14 is rotatably connected to the processing table 10 to ensure the stability of the rotating shaft 14 during rotation. Multiple external scraper structures are spirally distributed on the outer surface of the rotating shaft 14. The external scraper structure includes an external scraper 15 and an adjustable scraper mounting frame structure 16. The scraper mounting frame structure 16 can adjust the height of the external scraper 15 and the distance between the external scraper 15 and the clay blank. The scraper mounting frame structure 16 is prior art, so its structure is not described in detail.
[0059] During the process of shaping the exterior of the clay blank, the height and position of the external scrapers 15 are first adjusted. Then, the rotating shaft 14 is driven to rotate by an external drive source such as a motor. As the rotating shaft 14 rotates, multiple external scrapers 15 gradually come into contact with the outer surface of the clay blank and perform shaping operations. The multiple external scrapers 15 have different shapes to shape the outer surface of the clay blank into a specific shape.
[0060] like Figures 1-4 The support 13 is equipped with a telescopic component 17, and the output end of the telescopic component 17 is rotatably connected to a rotating pressure plate 18, which is in contact with the surface of the clay blank.
[0061] After the clay blank is placed on the rotating storage cylinder 11, the rotating pressure plate 18 is adjusted by the telescopic component 17 so that the rotating pressure plate 18 contacts the surface of the top of the clay blank, thereby limiting the clay blank in the radial direction. During the rotation of the clay blank, the rotating pressure plate 18 rotates accordingly to ensure the stability of the clay blank during the rotation process.
[0062] It should be noted that the bottom side of the rotating pressure plate 18 is a smooth plane, which can prevent the rotating pressure plate 18 from affecting the appearance of the clay blank, and the telescopic component 17 can be a component or structure with telescopic function such as an electric push rod or a hydraulic rod.
[0063] like Figure 2 , Figure 4 and Figures 6-9 Multiple support rods 28 are fixedly connected to the top side of the support frame 21. The multiple support rods 28 are arranged in a circular array about the center of the internal tool holder mounting platform 20. The top of each of the multiple support rods 28 is fixedly connected to the bottom side of the supporting frustum 30 to ensure the stability of the supporting frustum 30. A flow guide shroud 29 is fixedly connected to the outer surface of the multiple support rods 28. The cross-sectional shape of the flow guide shroud 29 is frustum-shaped. A scraper assembly is provided between each support rod 28 and the lead screw 50. The scraper assembly is used to clean the mud adhering to the flow guide shroud 29.
[0064] During the drilling process of the scraper 53, the mud generated during drilling falls from the gap between the sleeve 52 and the connecting hole 311 onto the guide shroud 29. The mud moves downward due to the slope of the guide shroud 29 and the gravity of the mud. Under the action of the slope of the guide shroud 29, the mud passes through the space between the rotating storage cylinder 11 and the internal tool holder mounting platform 20 and enters the interior of the processing table 10, thereby completing the mud collection operation and avoiding the accumulation of mud inside the clay blank. The guide shroud 29 has a perforation, and the guide rod 54 passes through the inside of the perforation. The diameter of the perforation is larger than the diameter of the guide rod 54, so that the guide rod 54 can move smoothly.
[0065] It should be noted that the guide shroud 29 is made of a smooth material such as ultra-high molecular weight polyethylene, and the inclination angle of the guide shroud 29 is not less than 15°, so that the mud has very little resistance when it slides down and can move smoothly downward without external assistance. In addition, a connecting hole is opened in the middle of the top of the guide shroud 29, and the lead screw 50 passes through the inside of the connecting hole. The outer diameter of the lead screw 50 is smaller than the diameter of the connecting hole, so that the lead screw 50 can rotate smoothly.
[0066] like Figures 6-9 The scraper assembly includes a scraper 55 rotatably connected to a support rod 28 and a rotating pusher 56 connected to a lead screw 50. The outer surface of the scraper 55 is in contact with the outer surface of the guide shroud 29. A limiting block 57 is fixedly connected to the outer surface of the support rod 28. A torsion spring 58 is connected between the limiting block 57 and the scraper 55. The scraper 55 and the rotating pusher 56 are positioned correspondingly. The opposite ends of the scraper 55 and the rotating pusher 56 are both semi-circular. The rotating pusher 56 is located below the nut 51 and above the top of the guide shroud 29.
[0067] Under normal circumstances, the mud material on the guide shroud 29 can fall automatically. If the mud material has a high viscosity, it may adhere to the guide shroud 29. During the shaping process of the mud blank, the lead screw 50 rotates accordingly. At this time, the rotating push plate 56 rotates and contacts multiple scrapers 55 in sequence, driving the scrapers 55 to rotate around the support rod 28. Because the end of the rotating push plate 56 opposite to the scraper 55 is arc-shaped, the rotating push plate 56 can contact the scraper 55 after pushing it to a specific angle. The 55 separation mechanism uses the rotation of the scraper 55 to scrape off the mud adhering to the guide shroud 29, thus separating the mud from the guide shroud 29. During the rotation of the scraper 55, the torsion spring 58 will generate torque. When the rotating push plate 56 separates from the scraper 55, the scraper 55 will return to its original position under the force of the torsion spring 58. If mud falls onto the scraper 55, the centrifugal force of the scraper 55 during rotation will separate the mud from the scraper 55, thereby keeping the surface of the guide shroud 29 clean.
[0068] It should be noted that multiple scraper assemblies and support rods 28 can be set so that the scraping range of multiple scraper assemblies can comprehensively cover the guide shroud 29, resulting in a better cleaning effect on the guide shroud 29.
[0069] like Figure 13 A gear ring 19 is fixedly connected to the outer surface of the rotating storage cylinder 11, and a gear 110 meshes with the outer surface of the gear ring 19. A drive unit is installed on the processing table 10, and the drive unit is connected to the gear 110. The drive unit is used to drive the gear 110 to rotate.
[0070] During the process of shaping and finishing the clay blank, the gear 110 is rotated by the drive component. At this time, the gear ring 19 will drive the rotating storage cylinder 11 to rotate, thereby causing the clay blank located on the rotating storage cylinder 11 to rotate and perform the shaping operation on the clay blank.
[0071] It should be noted that both the gear ring 19 and the gear 110 are located inside the machining table 10, which can greatly avoid the influence of external factors on the gear ring 19 and the gear 110, thus ensuring the normal transmission of the gear ring 19 and the gear 110.
[0072] like Figures 1-4 The processing table 10 is equipped with a conveyor belt 60, which is located below the rotating storage cylinder 11 and passes through the processing table 10. Two chip removal grooves 101 are opened on the top side of the processing table 10. The external blank removal tool assembly is located in the middle of the two chip removal grooves 101. A mudguard 61 is connected to the processing table 10, and the mudguard 61 corresponds to the position of the chip removal grooves 101.
[0073] During the drilling process of the clay blank, the clay material generated enters the interior of the processing table 10 through the hollow between the rotating storage cylinder 11 and the internal tool holder mounting platform 20 and falls onto the conveyor belt 60. During the process of trimming the outer surface of the clay blank by the external trimming tool assembly, the clay material generated enters the interior of the processing table 10 through the chip discharge trough 101 and falls onto the conveyor belt 60. The conveyor belt 60 transports the clay material to the outside of the processing table 10, and the end of the conveyor belt 60 can be connected to a clay material recovery structure, so that the clay material can be automatically collected and recovered. The mud baffle 61 can prevent the clay material from splashing during the trimming process of the external trimming tool assembly, so that the clay material can accurately enter the interior of the processing table 10 through the chip discharge trough 101.
[0074] like Figure 13 A mudguard 111 is fixedly connected to the outer surface of the rotating storage cylinder 11. The mudguard 111 is located above the bearing 12, and the maximum diameter of the mudguard 111 is greater than the outer diameter of the bearing 12. The mudguard 111 can prevent mud from falling on the bearing 12 and avoid the mud from affecting the bearing 12.
[0075] like Figure 4 and Figure 6 The processing table 10 is equipped with a mounting bracket 112. The mounting bracket 112 is L-shaped and passes through the bottom of the rotating storage cylinder 11 and connects to the bottom of the internal tool holder mounting table 20 to ensure the structural stability of the internal tool holder mounting table 20.
[0076] It should be noted that the clay blanks mentioned in the above documents are all double-plate disc-shaped suspension porcelain insulator clay blanks after being pressed and formed.
