Abstract

This invention relates to the field of spacer bar processing equipment, specifically disclosing a forging die for processing nano-anti-aging spacer bars for ultra-high voltage transmission lines. The die includes a lower die assembly and an upper die assembly, the upper die assembly being positioned directly above the lower die assembly.

Once the branches are filled, the moving plates move downwards, and the raw material gradually fills the inner annular cavity. This achieves a filling method from the outside in during raw material injection, avoiding molding defects caused by cavities in the corner branches of the die cavity. Simultaneously, the trapezoidal moving plates accelerate the flow of the raw material, further improving the molding speed and avoiding the problem of slow flow rates due to the doping of nanomaterials in the raw material, which leads to excessively slow molding speeds.

Description

Technical Field

[0001] This invention relates to the field of spacer processing equipment technology, specifically a forging die for processing nano-anti-aging spacers for ultra-high voltage transmission lines. Background Technology

[0002] In the construction of ultra-high voltage (UHV) transmission lines, nano-anti-aging spacers are key components, and their processing quality directly affects the safe operation and service life of the lines. The forging die used in the processing of nano-anti-aging spacers aims to improve the mechanical properties and corrosion resistance of the product by optimizing the material forming process. Through precise structural design, this die achieves efficient forging of nano-aluminum alloy materials, ensuring the strength, toughness, and anti-aging properties of the spacer frame. It is widely used in the power engineering field and is of great significance for ensuring the stability of high-voltage transmission systems.

[0003] Traditional spacer forging dies have significant shortcomings. In terms of material filling, traditional dies often employ a single-cavity structure, which is ill-suited to the poor flowability of nanomaterials. This leads to insufficient filling in the corner areas of the cavity, easily forming voids or shrinkage cavities, reducing product strength and density. Molding efficiency is low, lacking a layered progressive filling mechanism, resulting in slow flow of nanomaterials within the die, extending production cycles and failing to meet the demands of large-scale production. During demolding, traditional dies rely on mechanical ejection or manual assistance, easily causing edge breakage or deformation, increasing the defect rate. Furthermore, the dies lack dynamic adjustment capabilities, failing to optimize molding parameters in real time based on material characteristics, thus failing to fully utilize the anti-aging properties of nanomaterials. These problems restrict the application of traditional dies in the production of nano-anti-aging spacers, necessitating improvements in their overall performance through layered filling, automated demolding, and adaptive adjustment technologies.

The mounting grooves in the same group are symmetrically arranged on both sides of the outer end of the mold cavity.

When it is necessary to form the spacer bar, the upper mold assembly can be moved down by the moving hydraulic system until the upper mold assembly and the lower mold assembly are completely fitted. Then, raw material is injected into the mold cavity in the base until the raw material is shaped in the mold cavity. Then, the upper mold assembly is driven to move up, and the shaped spacer bar is taken out from the mold cavity for further forging.

[0016] (III) Beneficial Effects

[0017] This invention provides a forging die for processing nano-anti-aging spacer bars for ultra-high voltage transmission lines. It has the following beneficial effects:

[0018] (I) The forging die for this spacer bar can be designed with a stacked moving plate. When the raw material is injected into the die cavity, the moving plate initially blocks the raw material and directs it into the corner branches of the die cavity. After the branches of the die cavity are filled, the moving plate moves down and the raw material begins to gradually fill the inner annular cavity. This achieves a filling method from the outside to the inside when the raw material is injected, avoiding the molding defects caused by the cavity at the corner branches of the die cavity. At the same time, the trapezoidal moving plate can also accelerate the flow of the raw material and further improve the molding speed, avoiding the problem of slow flow rate caused by the doping of nanomaterials in the raw material, which leads to the slow molding speed.

[0019] (II) The forging die used for this spacer bar processing, after the upper and lower die groups are engaged, the engagement ring compresses the extrusion column, causing the extrusion column to move into the extrusion cavity. This increases the air pressure in the extrusion cavity and delivers it to the elastic telescopic rod. The elastic telescopic rod then pushes the sliding plate to slide along the mounting groove, ensuring the edge of the die cavity is completely closed. When the upper die group moves upward, the extrusion column is moved upward through electromagnetic adsorption, causing the sliding plate to slide into the mounting groove. This causes the sliding plate to detach from the contact with the formed spacer bar, significantly reducing the problem of spacer bar branches breaking when removed from the die cavity. At the same time, the upward-moving column drives the moving plate and ejector rod to move upward, ejecting the formed spacer bar from the lower die group. This not only achieves rapid disassembly of the spacer bar but also provides a certain degree of protection for the spacer bar, reducing the generation of defective products.

[0020] (III) The forging die used for this spacer bar processing, when the upper die group moves upward, injects raw material into the storage ring through the injection pipe to replenish it. As the upper and lower die groups are engaged, the storage ring is directly above the die cavity, and the injection hole on the storage ring is aligned with the moving plate. At this time, as the hydraulic system continues to move downward, it will drive the extrusion ring downward through the support rod, and the insertion post will also move downward synchronously. As the insertion post moves downward, the connecting rod will slide in the limiting groove on the side surface of the insertion post. The near-L-shaped limiting groove ensures that the connecting rod initially slides in the limiting groove as the insertion post moves downward. The rotation begins, causing the rotating ring connected to its outer end to slide at the bottom of the storage ring. Eventually, the misalignment hole of the rotating ring connects with the injection hole of the storage ring. At this point, due to the high pressure inside the storage ring caused by the extrusion ring, raw materials begin to be injected into the mold cavity. As the insertion post continues to move downward, it eventually drives the moving post downward, thus moving the moving plate downward until the mold cavity is completely formed. By setting the upper and lower mold groups to cooperate with each other, the forming process of the spacer bar can be fully automated, greatly improving the forming speed, reducing the difficulty of operation, and making it easy to use.

[0031] 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.

[0032] First embodiment: as follows Figures 1 to 9 As shown, the present invention provides a technical solution: a forging die for processing nano-anti-aging spacer bars for ultra-high voltage transmission lines, comprising a lower die group 1, which is fixedly mounted on a processing machine tool by bolts, and further comprising:

[0033] Upper module 2 is positioned directly above lower module 1, with the top of upper module 2 fixedly connected to the hydraulic system on the machine tool.

[0034] The lower module 1 includes a chassis 11, and a mold cavity 12 is provided on the upper surface of the chassis 11. A movable plate 13 is provided in the mold cavity 12. Three movable plates 13 are set as a group. The movable plates 13 are arranged at fixed intervals along the central axis of the mold cavity 12 in six groups. The inner surface of the innermost movable plate 13 in the same group slides against the inner surface of the mold cavity 12.

[0035] The three movable plates 13 in the same group are arranged in a trapezoidal shape, and the three movable plates 13 in the same group are elastically fitted and slidably connected to each other, with six groups of movable plates 13 penetrating the bottom of the mold cavity 12.

[0036] The lower surface of the lower module 1 is fixedly connected to a retaining ring 14 by a connecting rod. The retaining ring 14 is located directly below the moving plate 13. The upper surface of the retaining ring 14 is provided with a sliding groove 15. A connecting plate 16 is slidably inserted into the sliding groove 15. The connecting plates 16 are fixedly spaced at six intervals around the central axis of the retaining ring 14. The top of the connecting plates 16 is fixedly connected to the bottom of the innermost moving plate 13 in the same group.

[0037] A movable ring 17 is fixedly connected to the bottom of the connecting plate 16. The movable ring 17 is located below the retaining ring 14. A bearing plate 18 is fixedly connected to the outer surface of the movable ring 17. The bearing plate 18 is fixedly spaced at six intervals around the central axis of the movable ring 17. An ejector rod 19 is fixedly connected to the upper surface of the bearing plate 18. The top of the ejector rod 19 slides through the base plate 11 and is located in the mold cavity 12. A movable column 110 is fixedly connected to the inner side of the movable ring 17 through a connecting rod. An electromagnetic device is installed on the movable column 110. A filling groove 111 is opened through the middle upper surface of the base plate 11. The movable column 110 is slidably connected in the filling groove 111, and the top of the movable column 110 is offset from the upper surface of the base plate 11.

[0038] The upper surface of the chassis 11 is provided with mounting grooves 112. The mounting grooves 112 are arranged symmetrically in pairs as a group. There are six groups of mounting grooves 112 arranged at fixed intervals around the central axis of the chassis 11. The mounting grooves 112 in the same group are symmetrically arranged on both sides of the outer end of the mold cavity 12. A sliding plate 113 is slidably connected in the mounting groove 112. An elastic telescopic rod 114 is fixedly connected to the side surface of the sliding plate 113 away from the mold cavity 12. The elastic telescopic rod 114 is fixedly embedded in the chassis 11.

[0039] The upper surface of the chassis 11 is provided with a compression cavity 115, and a compression column 116 is elastically slidably connected inside the compression cavity 115. The top of the compression column 116 initially protrudes from the compression cavity 115. The compression cavity 115 is connected to the internal cavity of the elastic telescopic rod 114. An electromagnetic device is provided on the compression column 116.

[0040] Second embodiment: as follows Figures 1 to 9As shown, the upper module 2 includes a fastening ring 21, which is attached to the upper surface of the chassis 11. A storage ring 22 is fixedly connected to the inner surface of the fastening ring 21. An injection hole is provided through the bottom of the storage ring 22. An injection tube 23 is fixedly connected through the outer surface of the storage ring 22. A central disk 24 is fixedly connected to the outer surface of the storage ring 22 away from the fastening ring 21. A plug-in post 25 is slidably inserted into the bottom surface of the central disk 24. A connecting post 251 is fixedly connected to the top of the plug-in post 25. The top of the connecting post 251 is provided through the upper surface of the central disk 24. A drive disk 26 is fixedly connected to the top of the connecting post 251.

[0041] A support rod 27 is fixedly connected to the bottom edge of the drive disc 26. The bottom of the support rod 27 passes through the central disc 24 and is fixedly connected to a compression ring 28. The support rod 27 is elastically inserted into the upper surface of the central disc 24. The compression ring 28 is initially set at the top of the storage ring 22. A limiting groove 29 is opened on the side surface of the insertion post 25. A connecting rod 210 is slidably inserted into the limiting groove 29. A mating groove 211 is opened through the bottom inner surface of the storage ring 22. The connecting rod 210 passes through the central disc 24 and is set in the mating groove 211. A rotating ring 212 is fixedly connected to the end of the connecting rod 210 away from the insertion post 25. The rotating ring 212 slides against the inner bottom surface of the storage ring 22. A misalignment hole 213 is opened through the rotating ring 212. The misalignment hole 213 and the injection hole at the bottom of the storage ring 22 are initially misaligned.

[0042] During operation, when the spacer bar needs to be formed, the upper mold 2 is moved downwards by the moving hydraulic system until it is fully fitted with the lower mold 1. Then, raw material is injected into the mold cavity 12 within the chassis 11 until it is shaped. Next, the upper mold 2 is driven upwards to remove the shaped spacer bar from the mold cavity 12 for further forging. When the locking ring 21 of the upper mold 2 is just engaged with the chassis 11, raw material is introduced into the mold cavity 12. As the hydraulic system continues to drive, the drive disc 26 moves downwards relative to the locking ring 21, which in turn drives the insertion pin 25 downwards within the central disc 24 via the connecting pin 251, gradually entering the filling groove 111 within the chassis 11 and gradually contacting the moving pin 110. The compression causes the moving column 110 to move downward within the filling groove 111, which in turn drives the moving ring 17 to move downward relative to the chassis 11. This, in turn, drives the moving plate 13 to move downward within the mold cavity 12 via the connecting plate 16. Since the moving plates 13 are arranged in a trapezoidal shape, under the pulling force of the moving plates 13, the same group of moving plates 13 initially move downward synchronously until the bottom of the outermost moving plate 13 contacts the upper surface of the retaining ring 14. The retaining ring 14 then causes the same group of moving plates 13 to gradually contract, until the upper surfaces of the same group of moving plates 13 contract to the same plane, filling the bottom of the mold cavity 12 and making the mold cavity 12 more complete. The layered design of the moving plates 13 ensures that the raw material is initially compressed when injected into the mold cavity 12. The obstruction of the moving plate 13 causes the raw material to flow into the corner branches of the mold cavity 12. Once the branches of the mold cavity 12 are filled, the moving plate 13 moves downward, and the raw material begins to gradually fill the inner annular cavity. This achieves a filling method from the outside to the inside during raw material injection, avoiding molding defects caused by cavities in the corner branches of the mold cavity 12. Simultaneously, the trapezoidal moving plate 13 can accelerate the flow of raw material, further improving the molding speed and avoiding the problem of slow flow rate due to the doping of nanomaterials in the raw material, which would result in excessively slow molding speed. After the upper mold group 2 and the lower mold group 1 are engaged, the engaging ring 21 compresses the extrusion column 116, causing the extrusion column 116 to move into the extrusion cavity 115. This increases the air pressure in the extrusion cavity 115 and transports it. The sliding plate 113 slides along the mounting groove 112 through the elastic telescopic rod 114, thus completely closing the edge of the mold cavity 12. When the upper mold 2 moves upward, the extrusion column 116 moves upward through electromagnetic adsorption, causing the sliding plate 113 to slide into the mounting groove 112. This causes the sliding plate 113 to disengage from the formed spacer bar, significantly reducing the problem of spacer bar branches breaking when removed from the mold cavity 12. At the same time, the moving column 110 moves the moving plate 13 and the ejector rod 19 upward, ejecting the formed spacer bar from the lower mold 1. This not only achieves rapid disassembly of the spacer bar but also provides a certain degree of protection for the spacer bar, reducing the generation of defective products. When the upper mold 2 moves upward,Raw materials are injected into the storage ring 22 through the injection pipe 23 to replenish the material. As the upper mold assembly 2 and lower mold assembly 1 are engaged, the storage ring 22 is positioned directly above the mold cavity 12, with the injection hole on the storage ring 22 aligned with the moving plate 13. At this point, as the hydraulic system continues to move downwards, the support rod 27 drives the extrusion ring 28 downwards, and simultaneously, the insertion post 25 also moves downwards. As the insertion post 25 moves downwards, the connecting rod 210 slides in the limiting groove 29 on the side surface of the insertion post 25. The near-L-shaped limiting groove 29 causes the connecting rod 210 to initially rotate as the insertion post 25 moves downwards, thereby promoting… The rotating ring 212, connected to its outer end, slides at the bottom of the storage ring 22. Eventually, the misalignment hole 213 of the rotating ring 212 connects with the injection hole of the storage ring 22. At this point, due to the high pressure within the storage ring 22 of the extrusion ring 28, raw material begins to be injected into the mold cavity 12. As the insertion post 25 continues to move downwards, it eventually drives the moving post 110 downwards, causing the moving plate 13 to move downwards until the mold cavity 12 is completely formed. By setting the upper mold group 2 and the lower mold group 1 to cooperate with each other, the forming process of the spacer bar can be fully automated, significantly improving the forming speed while reducing the difficulty of operation and making it easier to use.
