Description

Technical Field

[0001] This invention relates to the field of ceramic insulator production technology, specifically to a device for shaping clay blanks for ceramic insulator production. Background Technology

[0002] Ceramic insulators, as indispensable insulating components in power systems, are widely used in overhead transmission lines, substations, and other locations. Their electrical performance and mechanical strength directly affect the safety and stability of the power grid operation. Ceramic insulators are typically manufactured using a wet molding process, which involves pressing prepared clay into shape in a mold, followed by trimming, drying, glazing, and firing to produce the finished product. Among these processes, the shaping of the clay blank is crucial in determining the insulator's geometric accuracy, structural integrity, and the efficiency of subsequent processing.

[0003] In existing technologies, the shaping of ceramic insulator blanks typically employs a step-by-step, multi-equipment collaborative production model. Specifically, the clay is first pressed into a solid or hollow cylindrical blank using a press and molds. This blank is then transferred to a dedicated finishing machine tool, where turning, scraping, and other methods are used to machine the required external contour structures for the insulator, such as skirts and grooves. This process involves multiple independent workstations, including pressing, blank transfer, secondary clamping, and finishing, and has the following significant drawbacks: Firstly, pressing and shaping and trimming are completed on separate equipment. The billet needs to be transferred between different workstations by manual labor or simple mechanical devices, which not only increases the auxiliary operation time, but also easily causes problems such as billet deformation, collision, and dehydration and cracking during the multi-process flow, directly affecting the billet quality and yield.

[0004] Secondly, existing pressing molds typically only have basic material holding and compaction functions, and cannot simultaneously complete the shaping of the insulator's outer contour during the molding process. After demolding, the blank needs to be cut a second time in the subsequent blank trimming process, resulting in the removal of a large amount of clay, which wastes raw materials, increases the trimming load, and makes the surface of the blank after cutting prone to micro-cracks, affecting the mechanical strength after sintering.

[0005] Third, existing technologies mostly use ejection mechanisms or manual knocking to extract the core mold from the blank, which can easily cause tearing, deformation or surface damage to the central hole wall of the blank. This problem is particularly prominent for slender hollow blanks with a large height-to-diameter ratio.

[0006] Fourth, to achieve blank trimming, the side mold needs to be opened after pressing to allow for the tool feed path. In existing devices, the side molds are mostly driven independently or manually adjusted, resulting in poor synchronization of opening and closing, and a lack of linkage control with the blank trimming components. This can easily lead to collisions between the tool and the mold due to disordered operation sequence, thus hindering the improvement of the equipment's automation level.

[0007] Fifth, in order to achieve the orderly execution of multiple actions such as bottom mold rotation, core mold lifting, and blank feeding, existing equipment usually needs to be equipped with multiple independent drive sources and corresponding sensor control systems. The equipment structure is bulky and costly, and the coordination of multiple power sources is difficult, making it difficult to achieve precise timing and process linkage. Summary of the Invention

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a device for shaping clay blanks for the production of ceramic insulators. It has the advantages of high integration, close process connection and reliable action coordination, so as to realize the whole process of integrated operation from clay filling, pressing and molding, outer contour trimming to core mold removal and blank cutting, thereby simplifying the production process, reducing blank flow damage, improving material utilization and production efficiency, and reducing equipment manufacturing costs and control complexity.

The top mold is arranged directly above the bottom mold and compacts the blank by pressing down. A blank trimming assembly is assembled to the outside of the side mold and fed radially toward the blank to process the blank into the outer contour of a ceramic insulator. An attitude adjustment component is used to drive the synchronous adjustment of the extension and retraction postures of each group of side molds.

[0019] Based on the above technical solutions, in order to ensure that the blank trimming assembly can be stably assembled on the mounting part and realize radial feeding along the blank, while avoiding spatial motion interference with the drive disk in the attitude adjustment assembly, the following technical solutions are provided.

[0020] The assembly table is provided with a feed slot, and the drive disk is provided with a fan-shaped slot that is arranged opposite to the feed slot.

[0021] Based on the above technical solutions, in order to ensure that the bottom mold can be stably assembled at the center of the assembly table and rotate stably around its own axis, and to ensure that the core mold can be stably assembled at the center of the bottom mold and move up and down along its own axis, the following technical solutions are provided.

[0022] A transmission sleeve is fixedly connected to the bottom of the bottom mold. The transmission sleeve passes through the axis of the drive disk and is arranged inside the assembly table. The flow splitting drive assembly maintains a power connection with the transmission sleeve.

[0023] The bottom of the core mold is coaxially fixed with a threaded section arranged in the transmission sleeve. A guide groove is provided on the side wall of the threaded section. The guide groove is slidably inserted with the assembly sleeve. A drive seat is screwed to the periphery of the threaded section. The drive seat is rotatably installed on the top of the assembly sleeve and is poweredly connected to the diversion drive assembly.

[0024] Based on the above technical solutions, in order to ensure that the separation drive component can be stably assembled in the mounting section and realize the power connection with the transmission sleeve, drive seat and adjusting screw, so as to drive the three to operate in coordination according to the set requirements, the following technical solutions are provided.

[0025] The diversion drive assembly includes a drive motor, a clutch mechanism, a ratchet mechanism, and a drive bevel gear B. The drive motor is fixedly mounted on the mounting bracket. The clutch mechanism and the drive bevel gear B are both assembled on the output shaft of the drive motor. The clutch mechanism is poweredly connected to the adjusting screw and the power on / off posture is adjusted.

[0026] Based on the above technical solutions, in order to ensure that the clutch mechanism can achieve power connection with the drive motor and the adjusting screw and perform on / off adjustment, the following technical solutions are provided.

[0027] The clutch mechanism includes an annular electromagnet, a transmission base, a permanent magnet, a locking male connector, and a locking female connector. The transmission base is fixedly mounted on the output shaft of the drive motor. The annular electromagnet is fixedly mounted on the mounting bracket and arranged around the output shaft of the drive motor. The permanent magnet is slidably inserted into the transmission base and is arranged opposite to the annular electromagnet. The locking male connector is fixedly mounted on the permanent magnet and arranged in the transmission base. The locking female connector is coaxially fixed to the adjusting screw and is arranged opposite to the locking male connector.

[0028] Based on the above technical solutions, in order to ensure that the ratchet mechanism can selectively transmit power to the drive motor and drive the transmission sleeve to operate stably, the following technical solutions are provided.

[0029] The ratchet mechanism includes an inner ratchet, a transmission ring, and a pawl. The inner ratchet is fixed to the transmission sleeve. The transmission ring is rotatably mounted on the transmission sleeve and maintains a power connection with the drive bevel gear B. The threaded section passes through the transmission ring. The pawl is rotatably mounted to the periphery of the transmission ring and maintains a meshing connection with the inner ratchet.

[0030] The beneficial effects of this invention are: 1. This solution integrates the two core processes of pressing and shaping into a single piece of equipment. Through the coordinated operation of the mold assembly and the shaping assembly, after the clay is die-cast into a hollow cylindrical blank, it can be directly shaped and shaped at the same station without the need for blank transfer or secondary clamping. This not only eliminates the need for blank transfer between the press and the shaping machine, avoiding wasted auxiliary operation time, but also eliminates the risk of blank damage caused by bumps, water loss, etc. during transfer, realizing continuous and compact production from clay to shaped blank, and significantly improving the output per unit time.

[0031] 2. The blank trimming assembly, through the scraping groove on the inner side of the scraper, can directly perform contour cutting on the rotating blank in a radial feed manner, forming a complete structure that meets the outer contour design requirements of the ceramic insulator in a single process. The blank is trimmed immediately after forming, resulting in uniform surface moisture and dense texture. The contour surface obtained after cutting is smooth and free of micro-cracks, providing a high-quality blank foundation for subsequent firing processes and helping to improve the electrical performance and mechanical strength of the finished insulator.

[0032] 3. This solution actively controls the lifting and lowering of the core mold through a flow-diverting drive component, allowing it to descend smoothly and at a constant speed along the axial direction until it is completely detached from the center hole of the blank. This dynamic demolding method overcomes the problems of hole wall tearing or deformation caused by instantaneous separation and uneven force in traditional ejection or hammering demolding methods. The core mold ejection process is synchronized with the blank rotation, and the relative movement between the two is smooth, significantly improving the demolding success rate and structural integrity of the hollow blank.

[0033] 4. The attitude adjustment component employs a worm gear mechanism in conjunction with a drive disc and arc-shaped guide grooves to achieve synchronous radial adjustment of each set of side molds. The worm gear and worm have unidirectional self-locking characteristics, maintaining stable locking during the side mold closing and pressing molding and during the blank removal and trimming process, effectively resisting the lateral extrusion force generated during clay die casting and preventing ineffective displacement of the side molds. Furthermore, the matching design of the fan-shaped through-slot and the feed through-slot ensures smooth feeding of the trimming component when the side molds are released; their movement paths do not interfere with each other, resulting in a compact and rational structural layout.

[0034] 5. This solution uses a split drive component with a single drive motor as the power source, and coordinates the switching of the clutch mechanism and the ratchet mechanism to achieve time-sharing and directional drive of three sets of actions: bottom mold rotation, core mold lifting, and blank trimming feed. The entire set of actions has clear logic and controllable timing, which not only avoids the increased cost and synchronization problems caused by independent drive of multiple motors, but also simplifies the design of the electrical control system, making the overall operation of the equipment more reliable and maintenance more convenient.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0038] Please see Figures 1-5 A device for shaping clay blanks for ceramic insulator production, comprising: Mold assembly 1 includes a bottom mold 11, side molds 12, top mold 13, and core mold 14, which are used to produce hollow cylindrical blanks. The bottom mold 11 can rotate around its own axis. The core mold 14 is slidably inserted into the axis of the bottom mold 11 and moves up and down along the vertical axis. The side molds 12 include multiple sets arranged in a ring array and assembled to the periphery of the bottom mold 11 in a radially adjustable manner. The top mold 13 is arranged directly above the bottom mold 11 and compacts the blank by pressing down. The blank trimming assembly 2 is assembled to the outside of the side mold 12 and fed radially toward the blank to process the blank into the outer contour of the ceramic insulator. The posture adjustment component 3 is used to drive the synchronous adjustment of the retraction and extension posture of each group of side molds 12. The flow divider drive assembly 4 works in conjunction with the bottom mold 11, the core mold 14, and the trimming assembly 2.

[0039] The clay blank shaping device provided in this solution can press-cast clay into hollow cylindrical blanks in a mold group, and process them into the outer contour of ceramic insulator strings with the blank trimming component 2. This can effectively improve the production efficiency of ceramic insulator strings. After the clay blank is shaped, its outer contour is corrected and shaped by the blank trimming component 2, and its structure is complete, so it can be directly fired.

[0040] In actual operation, the posture adjustment component 3 first controls the retraction and splicing of each group of side molds 12, and raises the top mold 13 to the position. At this time, the top mold 13 is at the top of the stroke and the top of the mold assembly 1 is in an open state, so as to facilitate the loading of a specific amount of clay into the mold assembly 1. Then, the top mold 13 is controlled to descend into the side mold 12 to continuously pressurize the clay, and then the bottom mold 11, side mold 12, top mold 13 and core mold 14 are combined to press-cast into a blank with a hollow cylindrical structure.

[0041] Then, the top mold 13 is controlled to move upward and reset. The attitude adjustment component 3 controls the release of each set of side molds 12 to make way for the feed path of the blank trimming component 2, so that the top and sidewalls of the blank are directly exposed. After this, the flow splitting drive component 4 drives the following actions synchronously: (1) The bottom mold 11 drives the billet on it to rotate continuously around its own axis; (2) The core mold 14 continues to descend to the bottom of its stroke and separates from the blank; (3) The blank trimming assembly 2 continuously feeds the blank radially to perform blank trimming operation on the outer wall of the running blank.

[0042] After the blank trimming assembly 2 is fed to a specific position and the blank is processed into a complete outer contour, the control diversion drive assembly 4 cuts off the power transmitted to the blank trimming assembly 2 and continues to drive the bottom mold 11 to rotate and the core mold 14 to descend. When the blank rotates with the bottom mold 11, the core mold 14 descends synchronously, which can achieve effective separation between the core mold 14 and the blank.

[0043] After the core mold 14 reaches the bottom of its stroke, the following actions are synchronously completed by the shunt drive component 4: (1) The core mold 14 continues to rise until it no longer comes into contact with the blank; (2) The blank trimming component 2 moves outward to make room for the blank to be cut.

[0044] After the blanking operation is completed, the following actions are continued to be performed by the flow divider drive component 4: (1) After the trimming assembly 2 moves outward to the end of its stroke, the power transmission of the split drive assembly 4 is disconnected; (2) The core mold 14 continues to rise to the top of the stroke.

[0045] At this point, the components of mold assembly 1 can be cleaned manually or with the help of automated cleaning equipment, while also removing any remaining clay residue from the worktable. The entire process is controlled by the diversion drive assembly 4, which effectively improves the coordinated operation of the bottom mold 11, core mold 14, and trimming assembly 2, thereby enhancing the automation level of the device. Example 2

[0046] Please see Figure 1 , Figure 2 , Figure 5 To ensure that the mold assembly 1, blank trimming assembly 2, posture adjustment assembly 3, and flow splitting drive assembly 4 can be stably assembled and operate in coordination, the following technical solutions are provided.

[0047] It also includes an installation part 5, which includes an assembly table 51, an assembly base 52, and an assembly bracket 53. The assembly table 51 is detachably arranged above the assembly base 52. An assembly sleeve 521 arranged inside the assembly table 51 is fixedly connected to the assembly base 52. An installation bracket 522 is fixedly connected to the assembly sleeve 521. The assembly bracket 53 is fixedly installed on the assembly table 51.

[0048] The bottom mold 11, side mold 12, and trimming assembly 2 are all assembled to the top of the assembly table 51. The core mold 14 is arranged in the assembly sleeve 521. The top mold 13 is assembled to the assembly bracket 53. The posture adjustment assembly 3 and the flow splitting drive assembly 4 are both assembled to the inside of the assembly table 51.

[0049] Setting the mounting section 5 as a split structure allows for easy independent processing and assembly of each component. This not only reduces the processing difficulty of each component but also enables the stable assembly of each functional component on the mounting section 5 through a detachable method, allowing them to operate in accordance with the set requirements. It also improves the ease of maintenance for each functional component.

[0050] To ensure that the top mold 13 can be stably assembled on the assembly bracket 53 and achieve stable lifting and lowering along the vertical axis, while avoiding spatial movement interference with the core mold 14, the following technical solution is provided.

[0051] A hydraulic telescopic cylinder 531, which is coaxially arranged with the bottom mold 11, is fixedly installed on the assembly bracket 53. The top mold 13 is fixedly installed to the movable end of the hydraulic telescopic cylinder 531. A clearance groove 131 is provided at the axis of the top mold 13 to slide and insert with the core mold 14.

[0052] The extension and retraction of the hydraulic telescopic cylinder 531 can drive the top mold 13 to adjust its lifting posture, thereby applying downward pressure to the top mold 13 to compact the clay in the mold assembly 1, ensuring the compactness of the hollow cylindrical blank produced, and thus improving the quality of the outer contour processing of the blank trimming assembly 2.

[0053] The placement groove 131 ensures that the top mold 13 can be inserted and engaged with the core mold 14 during the pressing action, thus preventing the presence of the core mold 14 from affecting the normal operation of the top mold 13. The placement groove 131 and the core mold 14 are in close contact, which can prevent the mud from being blocked by the core mold 14 and entering the placement groove 131. A vent is also provided at the top of the placement groove 131 to prevent the internal air from being unable to escape when the core mold 14 is engaged with the placement groove 131. Example 3

[0054] Please see Figures 2-5 To ensure that each set of side molds 12 can be stably assembled on the mounting part 5 and achieve stable retraction and adjustment, while ensuring that the side molds 12 can resist the reverse tilting force provided by the clay material during the die casting process, the following technical solution is provided.

[0055] The top surface of the assembly table 51 has multiple sets of radial through grooves 511 arranged in an annular array. The outer wall of the side mold 12 is fixedly connected to a support member 121. The bottom of the support member 121 is fixedly connected to a guide pin seat 122 that maintains a sliding fit with the radial through grooves 511.

[0056] The support member 121 is provided with an inclined support structure, which can provide stable lateral support to the side mold 12, thereby effectively resisting the lateral tilting force and improving the structural strength of the side mold 12. The guide pin seat 122 provided at the bottom of the support member 121 cooperates with the radial guide groove to ensure that each set of side molds 12 can be stably adjusted in the radial direction.

[0057] It should also be noted that the transverse section of the support member 121 is relatively large, which can completely block the radial through groove 511. That is, no matter where the support member 121 moves, it can effectively cover the radial through groove 511 to prevent mud residue from entering the assembly table 51 through the radial through groove 511 and interfering with the operational stability of each functional component.

[0058] To ensure that the attitude adjustment component 3 can be stably assembled in the assembly table 51 and to achieve synchronous retraction and adjustment of each set of side molds 12, while avoiding invalid displacement of the side molds 12 due to the extrusion of mud, the following technical solution is provided.

[0059] The attitude adjustment assembly 3 includes a drive disk 31, an adjustment motor 32, and a worm gear 331 and a worm 332 that are matched together. The drive disk 31 has arc-shaped guide grooves 311 arranged in a ring array. The arc-shaped guide grooves 311 are matched and inserted into the guide pin seat 122. The drive disk 31 is rotatably installed in the assembly table 51 and arranged around the bottom mold 11. The adjustment motor 32 is fixedly installed on the mounting bracket 522. The worm gear 331 and the worm 332 are both rotatably installed on the mounting bracket 522. The output shaft of the adjustment motor 32 is coaxially fixedly connected to the worm 332. A drive bevel gear A333 is fixedly connected to the axis of the worm gear 331. A transmission bevel gear 312 that is meshed with the drive bevel gear A333 is fixedly connected to the axis of the drive disk 31.

[0060] The mounting bracket 522 ensures the stable assembly of components such as the adjusting motor 32, worm gear 331, and worm 332. By setting the drive bevel gear A333 and the transmission bevel gear 312, the power can be vertically redirected, so that the assembly position of the adjusting motor 32, worm gear 331, and worm 332 is located on the periphery of the bottom mold 11, thereby avoiding spatial movement interference with the bottom mold 11.

[0061] When the attitude adjustment component 3 is running, the power of the adjustment motor 32 can be transmitted to the drive disk 31 through the worm 332, worm wheel 331, drive bevel gear A333, and transmission bevel gear 312, thereby driving the drive disk 31 to operate stably. The arc-shaped guide groove 311 on the drive disk drives the guide pin seat 122 on the side mold 12 to slide stably along the radial guide groove, thereby realizing the synchronous retraction and extension adjustment of each group of side molds 12.

[0062] The combination of worm 332 and worm wheel 331 also has a one-way self-locking characteristic. That is, when the regulating motor 32 stops and the worm 332 is in a stationary state, the worm wheel 331 is locked in a state that cannot rotate due to the structural restriction of the worm 332, thereby ensuring that the drive disk 31 and the side mold 12 always remain in a stationary and locked state, thus avoiding the side mold 12 from being ineffectively offset by the extrusion of mud. Example 4

[0063] Please see Figure 1 , Figure 2 , Figures 5-7 To ensure that the blank trimming assembly 2 can be stably assembled on the mounting part 5 and realize radial feeding along the blank, while avoiding spatial motion interference with the drive disk 31 in the attitude adjustment assembly 3, the following technical solution is provided.

[0064] The assembly table 51 has a feed channel 512, and the drive plate 31 has a fan-shaped channel 313 that is arranged opposite to the feed channel 512. The trimming assembly 2 includes a scraper 21, a sliding guide rod 22, and an adjusting screw 23. The inner side of the scraper 21 has a scraping groove 211 for processing the outer contour of the ceramic insulator. The sliding guide rod 22 is fixedly connected to the scraper 21. The sliding guide rod 22 passes through the fan-shaped channel 313 and is slidably connected to the feed channel 512 and the mounting bracket 522. The adjusting screw 23 is rotatably mounted on the mounting bracket 522. The adjusting screw 23 is screwed to the sliding guide rod 22. The diversion drive assembly 4 is poweredly connected to the adjusting screw 23.

[0065] The setting of the feed channel and the mounting bracket 522 can ensure that the sliding guide rod 22 is stably assembled on it and fed radially along the blank. When the adjusting screw 23 is driven to operate by the diversion drive assembly 4, the sliding guide rod 22 and the scraper 21 can be driven to feed stably along the feed channel 512, thereby realizing the effective processing of the outer contour of the blank.

[0066] The fan-shaped through slot 313 ensures that the sliding guide rod 22 always moves within it, and that the two never interfere with each other in spatial movement when the drive disk 31 is in its operating posture.

[0067] It should also be noted that an isolation plate 221 arranged above the feed channel 512 is fixedly connected to the sliding guide rod 22. When the sliding guide rod 22 drives the isolation plate 221 to move, the isolation plate 221 can always block the feed channel 512, thereby preventing mud from entering the inner side of the assembly table 51 through the feed channel 512 and affecting the operational stability of related components.

[0068] To ensure that the bottom mold 11 can be stably assembled at the axis of the assembly table 51 and rotate stably around its own axis, and to ensure that the core mold 14 can be stably assembled at the axis of the bottom mold 11 and move up and down along its own axis, the following technical solutions are provided.

[0069] A transmission sleeve 111 is fixedly connected to the bottom of the bottom mold 11. The transmission sleeve 111 passes through the axis of the drive disk 31 and is arranged inside the assembly table 51. The diversion drive assembly 4 maintains a power connection with the transmission sleeve 111.

[0070] The bottom of the core mold 14 is coaxially fixed with a threaded section 141 arranged in the transmission sleeve 111. A guide groove 142 is provided on the side wall of the threaded section 141. The guide groove 142 is slidably inserted with the mounting sleeve 521. A drive seat 143 is screwed onto the periphery of the threaded section 141. The drive seat 143 is rotatably installed on the top of the mounting sleeve 521 and is poweredly connected to the diversion drive assembly 4.

[0071] The bottom mold 11 is rotatably mounted to the top axis of the assembly table 51, and the transmission sleeve 111 is arranged inside the assembly table 51. The transmission sleeve 111 and the bottom mold 11 can be driven to operate stably by the diversion drive assembly 4.

[0072] The core mold 14 is axially arranged through the bottom mold 11 and the transmission sleeve 111, and cooperates with the mounting sleeve 521 through the guide groove 142 provided on it to achieve stable lifting and lowering adjustment along the vertical axis. When the diversion drive assembly 4 drives the drive seat 143 to operate, it can drive the threaded section 141 to drive the core mold 14 to achieve lifting and lowering adjustment along the vertical axis. Example 5

[0073] Please see Figures 6-9 To ensure that the separation drive assembly can be stably assembled in the mounting section 5 and to achieve power connection with the transmission sleeve 111, drive seat 143 and adjusting screw 23 so as to drive the three to operate in coordination according to the set requirements, the following technical solution is provided.

[0074] The diversion drive assembly 4 includes a drive motor 41, a clutch mechanism 42, a ratchet mechanism 43, and a drive bevel gear B44. The drive motor 41 is fixedly mounted on the mounting bracket 522. The clutch mechanism 42 and the drive bevel gear B44 are both assembled on the output shaft of the drive motor 41. The clutch mechanism 42 maintains a power connection with the adjusting screw 23 and adjusts the power on / off posture. The drive bevel gear B44 maintains a power connection with the ratchet mechanism 43 and the drive seat 143.

[0075] An upper bevel gear 431 is mounted at the input end of the ratchet mechanism 43, and a lower bevel gear 144 is mounted on the drive seat 143. The upper bevel gear 431 and the lower bevel gear 144 are symmetrically arranged and are both meshed with the drive bevel gear B44. When the drive motor 41 rotates in the forward or reverse direction, the drive seat 143 can be driven to rotate in the forward or reverse direction through the combination of the drive bevel gear B44 and the lower bevel gear 144, thereby driving the threaded section 141 and the spindle to rise and fall stably in the vertical direction.

[0076] The ratchet mechanism 43 can only receive unidirectional power from the drive motor 41. That is, when the drive motor 41 rotates in the forward direction, it can stably transmit power to the ratchet mechanism 43 through the drive bevel gear B44 and the upper bevel gear 431, so that the ratchet mechanism 43 can drive the transmission sleeve 111 and the bottom mold 11 to operate stably. However, when the drive motor 41 rotates in the reverse direction, the power transmitted to the upper bevel gear 431 cannot drive the output end of the ratchet mechanism 43 to operate, so that the transmission sleeve 111 and the bottom mold 11 remain stationary.

[0077] By adjusting the power on / off state of the clutch mechanism 42, the power of the drive motor 41 can be controlled to be transmitted to or cut off from the adjusting screw 23, thereby controlling the operating state of the trimming assembly 2 according to the operation procedure.

[0078] To ensure that the clutch mechanism 42 can achieve power connection with the drive motor 41 and the adjusting screw 23 and perform on / off adjustment, the following technical solution is provided.

[0079] The clutch mechanism 42 includes an annular electromagnet 421, a transmission base 422, a permanent magnet 423, a locking male connector 424, and a locking female connector 425. The transmission base 422 is fixedly mounted on the output shaft of the drive motor 41. The annular electromagnet 421 is fixedly mounted on the mounting bracket 522 and arranged around the output shaft of the drive motor 41. The permanent magnet 423 is slidably inserted into the transmission base 422 and is arranged opposite to the annular electromagnet 421. The locking male connector 424 is fixedly mounted on the permanent magnet 423 and arranged in the transmission base 422. The locking female connector 425 is coaxially fixed to the adjusting screw 23 and is arranged opposite to the locking male connector 424.

[0080] By controlling the direction and intensity of the current input to the annular electromagnet 421, the direction of the magnetic poles of the annular electromagnet 421 can be changed, thereby generating an attractive or repulsive force on the permanent magnet 423 and the locking male connector 424. When the annular electromagnet 421 pulls the permanent magnet 423 and the locking male connector 424 into the transmission seat 422, the locking male connector 424 and the locking female connector 425 are in a separated state. At this time, the power of the drive motor 41 cannot be transmitted to the locking female connector 425 through the transmission seat 422 and the locking male connector 424, so that the locking female connector 425 and the adjusting screw 23 are in a stationary state. At this time, the blank trimming assembly 2 is in a stationary state.

[0081] When the annular electromagnet 421 pushes the permanent magnet 423 and the locking male connector 424 out of the transmission seat 422, the locking male connector 424 and the locking female connector 425 are in a nested locking state. At this time, the power of the drive motor 41 can be transmitted to the locking female connector 425 through the transmission seat 422 and the locking male connector 424, so that the locking female connector 425 and the adjusting screw 23 receive the power of the drive motor 41 and operate, thereby driving the blank trimming assembly 2 to achieve the feeding or retraction action.

[0082] To ensure that the ratchet mechanism 43 can selectively transmit power to the drive motor 41 and drive the transmission sleeve 111 to operate stably, the following technical solution is provided.

[0083] The ratchet mechanism 43 includes an inner ratchet 432, a transmission ring 433, and a pawl 434. The inner ratchet 432 is fixed to the transmission sleeve 111. The transmission ring 433 is rotatably mounted on the transmission sleeve 111 and maintains a power connection with the drive bevel gear B44. The threaded section 141 passes through the transmission ring 433. The pawl 434 is rotatably mounted on the periphery of the transmission ring 433 and maintains a meshing connection with the inner ratchet 432.

[0084] The transmission ring 433 is fixedly connected to the upper bevel gear 431 as the input end of the ratchet mechanism 43. The power of the drive motor 41 can drive the transmission ring 433 to operate stably through the drive bevel gear B44. A spring is also installed on the periphery of the transmission ring 433 to keep in contact with the pawl 434, so that the pawl 434 is always in an outwardly extended position and keeps in cooperation with the ratchet teeth on the inner ratchet 432.

[0085] When the drive motor 41 rotates in the forward direction, the transmission ring 433 can drive the inner ratchet 432 and the transmission sleeve 111 to operate stably through the pawl 434. However, when the drive motor 41 rotates in the reverse direction, the pawl 434 and the inner ratchet 432 are in a slipping state, and the power cannot be transmitted to the inner ratchet 432 through the transmission ring 433 and the pawl 434, so that the inner ratchet 432 and the transmission sleeve 111 are in a stationary state.

[0086] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

[0087] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
