Description

Technical Field

[0001] The present invention relates to the technical field of spacer processing equipment, and more specifically, it is a forging die for processing nano anti-aging spacers for ultra-high voltage transmission lines. Background Art

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

[0003] Traditional spacer forging dies have significant deficiencies. In terms of material filling, traditional dies mostly adopt a single cavity structure, which is difficult to adapt to the poor fluidity of nano materials, resulting in insufficient filling in the corner areas of the mold cavity, easily forming cavities or shrinkage holes, and reducing the strength and density of products. The forming efficiency is low, lacking a layered progressive filling mechanism, and the flow rate of nano materials in the die is slow, prolonging the production cycle and making it difficult to meet the requirements of large-scale production. During the demolding process, traditional dies rely on mechanical ejection or manual assistance, which easily causes edge fracture or deformation of products, increasing the defective rate. In addition, the die lacks a dynamic adjustment function and cannot optimize the forming parameters in real time according to the material characteristics, resulting in the failure to fully exert the anti-aging performance of nano materials. These problems restrict the application of traditional dies in the production of nano anti-aging spacers and urgently need to improve their comprehensive performance through layered filling, automatic demolding and adaptive adjustment technologies.

[0016] (III) Beneficial effects

[0017] The present 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 processing the spacer rods can make the raw materials flow into the corner branches of the mold cavity due to the blocking of the moving plates when the raw materials are injected into the mold cavity. When the branches of the mold cavity are filled, the moving plates move down and the raw materials begin to gradually fill the inner annular cavity, thereby realizing the filling method from outside to inside when the raw materials are injected, avoiding the molding defects caused by the cavities in the corner branches of the mold cavity. At the same time, the trapezoidal moving plates can also speed up the flow of the raw materials and further improve the molding speed, avoiding the problem of slow molding speed caused by the slow flow rate of the raw materials doped with nanomaterials.

[0019] (ii) The forging die for processing the spacer rods, after the upper die set and the lower die set are fastened together, the fastening ring can extrude the extrusion column, so that the extrusion column moves into the extrusion cavity, causing the air pressure in the extrusion cavity to increase and be transported to the elastic telescopic rod, and then the elastic telescopic rod pushes the sliding plate to slide along the installation groove, so that the edge of the cavity is completely closed, and when the upper die set moves upward, the extrusion column is driven upward by electromagnetic adsorption, thereby prompting the sliding plate to slide into the installation groove, causing the sliding plate to break away from the contact with the formed spacer rod, thereby greatly reducing the problem of the spacer rod branch breaking when taking out the cavity, and at the same time, the upward moving column drives the moving plate and the ejector rod to move upward, and the formed spacer rod is ejected from the lower die set, which not only realizes the rapid disassembly of the spacer rod, but also provides a certain degree of protection for the spacer rod, thereby reducing the production of defective products.

[0020] (III) The forging die for processing the spacer rods is such that when the upper die set moves upward, raw materials are injected into the storage ring through the injection pipe for replenishment. As the upper die set and the lower die set are fastened together, the storage ring is directly above the die cavity, and the injection hole on the storage ring is directly opposite to the movable plate. At this time, as the hydraulic system continues to move downward, the extrusion ring is driven downward through the support rod, and the plug-in column also moves downward synchronously. As the plug-in column moves downward, the connecting rod slides in the limit groove on the side surface of the plug-in column. Through the nearly L-shaped limit groove, the connecting rod is initially moved downward as the plug-in column moves downward. It starts to rotate, which causes the rotating ring connected to its outer end to slide at the bottom of the storage ring, and finally the offset hole of the rotating ring is connected to the injection hole of the storage ring. At this time, due to the high pressure inside the extrusion storage ring of the extrusion ring, raw materials begin to be injected into the mold cavity, and as the plug-in column continues to move downward, it eventually starts to drive the moving column to move downward, that is, the moving plate moves downward, until the mold cavity is completely formed. By arranging the upper mold group and the lower mold group to cooperate with each other, the forming of the spacer rod can be fully automated, which greatly improves the forming speed, reduces the difficulty of operation, and is easy to use.

An electromagnetic is arranged on the extrusion column 116.

[0040] Second Embodiment: As Figures 1 to 9As shown in the figure, the upper module 2 includes a fastening ring 21. The fastening ring 21 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. Injection holes are provided through the bottom of the storage ring 22. A material injection pipe 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 on the side away from the fastening ring 21. A plugging column 25 is slidably inserted into the bottom surface of the central disk 24. A connecting column 251 is fixedly connected to the top of the plugging column 25. The top of the connecting column 251 penetrates through the upper surface of the central disk 24. A driving disk 26 is fixedly connected to the top of the connecting column 251.

[0041] A support rod 27 is fixedly connected to the bottom surface of the edge of the driving disk 26. The bottom of the support rod 27 penetrates through the central disk 24 and is fixedly connected to a pressing ring 28. The support rod 27 is elastically inserted into the upper surface of the central disk 24. The pressing ring 28 is initially arranged on the top of the storage ring 22. A limiting groove 29 is provided on the side surface of the plugging column 25. A connecting rod 210 is slidably inserted into the limiting groove 29. A matching groove 211 is provided through the inner surface of the bottom of the storage ring 22. The connecting rod 210 penetrates through the central disk 24 and is arranged in the matching groove 211. A rotating ring 212 is fixedly connected to the end of the connecting rod 210 away from the plugging column 25. The rotating ring 212 is slidably attached to the inner bottom surface of the storage ring 22. A misaligned hole 213 is provided through the rotating ring 212. The misaligned hole 213 and the injection hole at the bottom of the storage ring 22 are initially misaligned.

[0042] During operation, when it is necessary to form the spacer rod, the upper die set 2 can be controlled to move downward by the mobile hydraulic system until the upper die set 2 is completely fitted with the lower die set 1, and then the raw materials are injected into the die cavity 12 in the chassis 11 until the raw materials are shaped in the die cavity 12, and then the upper die set 2 is driven to move upward, and the shaped spacer rod is taken out of the die cavity 12 for further forging, and when the buckling ring 21 of the upper die set 2 is just buckled with the chassis 11, the raw materials are introduced into the die cavity 12. At this time, as the hydraulic system continues to drive, the driving disk 26 will continue to move downward relative to the buckling ring 21, and then the plug-in column 25 will be driven to move downward in the center disk 24 through the connecting column 251, gradually entering the filling groove 111 in the chassis 11, and gradually contacting and contacting with the moving column 110 and The movable column 110 is squeezed, so that the movable column 110 moves downward in the filling groove 111, and then the movable ring 17 is driven to move downward relative to the chassis 11, thereby driving the movable plate 13 to move downward in the mold cavity 12 through the connecting plate 16. Since the movable plates 13 are arranged in a trapezoidal shape in threes, the same group of movable plates 13 initially start to move downward synchronously under the pulling force of the movable plates 13 until the bottom of the outermost movable plate 13 contacts the upper surface of the retaining ring 14, and the movable plates 13 in the same group begin to gradually shrink through the obstruction of the retaining ring 14, and finally the upper surfaces of the same group of movable plates 13 shrink into the same plane, filling the bottom of the mold cavity 12, so that the mold cavity 12 tends to be complete. The movable plates 13 with a stacked design can make the raw materials initially move downward due to the injection into the mold cavity 12. The blocking of the moving plate 13 causes the raw material to enter the corner branches of the mold cavity 12. When the branches of the mold cavity 12 are filled, the moving plate 13 moves down, and the raw material begins to gradually fill the inner annular cavity, thereby realizing a filling method from the outside to the inside when the raw material is injected, avoiding the molding defects caused by the cavities in the corner branches of the mold cavity 12. At the same time, the trapezoidal setting of the moving plate 13 can also accelerate the flow effect of the raw material to further improve the molding speed, avoiding the problem of slow flow rate caused by the doping of nanomaterials in the raw material resulting in too slow molding speed. After the upper mold group 2 and the lower mold group 1 are buckled, the buckling ring 21 completes the extrusion of the extrusion column 116, so that the extrusion column 116 moves into the extrusion cavity 115, causing the air pressure in the extrusion cavity 115 to increase and transport it. The elastic telescopic rod 114 pushes the sliding plate 113 to slide along the installation groove 112 through the elastic telescopic rod 114, so that the edge of the mold cavity 12 is completely closed. When the upper mold assembly 2 moves upward, the extrusion column 116 is driven upward by electromagnetic adsorption, thereby prompting the sliding plate 113 to slide toward the installation groove 112, causing the sliding plate 113 to break away from the contact with the formed spacer bar, thereby greatly reducing the problem of the spacer bar branch breaking when taking out the mold cavity 12. At the same time, the upward moving column 110 drives the moving plate 13 and the ejector rod 19 to move upward, and the formed spacer bar is ejected from the lower mold assembly 1, which not only realizes the rapid disassembly of the spacer bar, but also provides a certain degree of protection for the spacer bar, thereby reducing the production of defective products. When the upper mold assembly 2 moves upward,That is, raw materials are injected into the storage ring 22 through the material injection pipe 23 for replenishment. As the upper module 2 and the lower module 1 are buckled together, the storage ring 22 is directly above the mold cavity 12, and the injection holes on the storage ring 22 are aligned with the moving plate 13. At this time, as the hydraulic system continues to move downward, the extrusion ring 28 will be driven to move downward by the support rod 27, and at the same time, the insertion column 25 will also move downward synchronously. As the insertion column 25 moves downward, the connecting rod 210 will slide in the limiting groove 29 on the side surface of the insertion column 25. Through the nearly L-shaped limiting groove 29, as the insertion column 25 moves downward, the connecting rod 210 will start to rotate initially, thereby promoting the sliding of the rotating ring 212 connected to its outer end at the bottom of the storage ring 22. Finally, the misalignment holes 213 of the rotating ring 212 are communicated with the injection holes of the storage ring 22. At this time, due to the extrusion of the extrusion ring 28, the inside of the storage ring 22 is in a high-pressure state, and the raw materials start to be injected into the mold cavity 12. As the insertion column 25 continues to move downward, finally, the moving column 110 starts to be driven to move downward, that is, the moving plate 13 moves downward until the mold cavity 12 is completely formed. By setting the upper module 2 and the lower module 1 to cooperate with each other, the forming process of the spacer bar can be fully automated, greatly improving the forming speed, reducing the operation difficulty at the same time, and being convenient to use.
