Description

Technical Field

[0001] This utility model relates to the field of wire reel technology, and in particular to a magnesium alloy wire reel. Background Technology

[0002] A spool (also known as a bobbin, winding reel, cable reel, etc.) is a device used for winding, storing, and protecting linear materials. Its core function is to facilitate the storage, transportation, and release of wires, while preventing damage from tangling, external pulling, or environmental factors. Wire spools are widely used in power engineering, communications, manufacturing, textiles, fisheries, 3D printing, and other fields.

[0003] Currently, the main materials for cable reels include steel, aluminum alloy, and plastic. Steel, due to its high density (7.8 g / cm³), has high handling and installation costs, making it suitable for heavy-duty cables but unsuitable for mobile equipment. Although aluminum alloy has a lower density (2.7 g / cm³) than steel, its specific strength is lower than that of magnesium alloy, requiring a thicker design for high-load applications. Furthermore, aluminum alloy's die-casting performance is inferior to that of magnesium alloy, making it more prone to porosity during die-casting, leading to a decrease in yield. It also requires an additional coating for electromagnetic shielding. While plastic cable reels have a low density (1.0-1.4 g / cm³), they are prone to deformation and cracking, unable to withstand heavy loads or high temperatures (>80°C), and are susceptible to aging and embrittlement from long-term exposure to ultraviolet radiation. Plastic is also difficult to degrade, posing a significant environmental challenge. Therefore, this application provides a magnesium alloy cable reel to meet these requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a magnesium alloy cable reel to address the issue that current cable reels, whose main materials are steel, aluminum alloy, and plastic, have high handling and installation costs, are suitable for heavy-duty cables, but are not suitable for mobile equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A magnesium alloy coil includes a support cylinder with pre-formed reinforcing ribs inside. The reinforcing ribs are arranged in a circular array along the inner wall of the support cylinder. The side plate is perpendicular to the axis of the support cylinder. The outer side plate has pre-formed first and second outer ring reinforcing ribs. Both the first and second outer ring reinforcing ribs are located in the groove of the side plate and are arranged in a circular array.

[0007] The inner ring of the side plate is located in the same plane as the side plate. The inner ring of the side plate has drainage holes, positioning holes and support holes in sequence from the outside to the inside. The drainage holes and positioning holes are arranged in a circular array. The support holes are located in the center of the inner ring of the side plate. A support ring is installed in the support hole. The central shaft passes through the central hole of the inner ring of both side plates and cooperates with the support hole and the support ring. The magnesium alloy ring welds the left and right support cylinders together by friction stir welding.

[0008] The cylinder has multiple reinforcing ribs, which are evenly distributed on the inner wall of the supporting cylinder to enhance its strength and prevent deformation.

[0009] The first side plate outer ring reinforcing rib and the second side plate outer ring reinforcing rib are both multiple. The multiple first side plate outer ring reinforcing ribs and the multiple second side plate outer ring reinforcing ribs are evenly distributed along the circumference of the side plate to increase the strength of the side plate, prevent the side plate from deforming, and at the same time improve the connection strength between the support cylinder and the side plate.

[0010] The drainage hole is used to discharge subsequent surface treatment liquid, the positioning hole is used for axial rotation positioning and limiting operation during the operation of the coil, and the support hole is used to pass through the support shaft and install the support ring.

[0011] The support ring is made of steel, which can reduce the friction of the support shaft rotation during the operation of the coil.

[0012] The central shaft passes through the central hole of the inner ring of both side discs and mates with the support hole and support ring.

[0013] The magnesium alloy ring is used for welding the left and right supporting cylinders during the friction stir welding stage.

[0014] The side plate is used to constrain the line from spreading outward, preventing the line from becoming tangled, and also to prevent the line from being damaged by external forces during operation.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] The above solution effectively enhances the strength of the supporting cylinder and side plates by designing reinforcing ribs for the cylinder body, the outer ring of the first side plate, and the outer ring of the second side plate. This disperses external forces, prevents deformation, and ensures the structural stability of the reel when carrying cables. It can withstand greater tension and pressure, ensuring the safety and reliability of cable winding, unwinding, and transportation. It also has advantages such as light weight, high strength, corrosion resistance, and environmental friendliness. It can effectively solve the problems existing in the current technology and has good market prospects and application value.

[0017] By using steel for the support ring and combining it with the central shaft, support hole, and support ring, the wear resistance of the support hole is significantly improved, the friction of the support shaft rotation is reduced, energy loss is reduced, and the service life of the coil is extended. At the same time, the support shaft rotates smoothly, reducing vibration and noise and improving operating performance.

[0018] The structural design of the side discs and inner rings effectively restrains the cable, preventing it from spreading and becoming tangled. Simultaneously, it blocks external impacts during operation, protecting the cable from damage and ensuring its integrity and quality. Attached Figure Description

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0025] The present invention provides a magnesium alloy wire reel in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0026] like Figures 1-2As shown, an embodiment of this utility model provides a magnesium alloy coil, including a support cylinder 1. The support cylinder 1 has pre-formed cylinder reinforcing ribs 2 inside. There are multiple cylinder reinforcing ribs 2, which are evenly distributed in a circular array along the inner wall of the support cylinder 1. The multiple evenly distributed cylinder reinforcing ribs 2 can effectively enhance the strength of the support cylinder 1. In actual use, when the coil is winding the cable, the support cylinder 1 may be subjected to external forces such as cable tension. The evenly distributed cylinder reinforcing ribs 2 can evenly disperse these external forces, thereby preventing the cylinder from deforming due to uneven force and ensuring that the support cylinder 1 can stably support the cable.

[0027] The side plate 3 is perpendicular to the axis of the support cylinder 1. It has pre-formed first and second outer ring reinforcing ribs 4 and 5 on its exterior. Both types of reinforcing ribs are located within the grooves of the side plate 3 and are arranged in a circular array. There are multiple first and second outer ring reinforcing ribs 4 and 5, evenly distributed along the circumference of the side plate 3. The main function of the side plate 3 is to constrain the cable from spreading outwards, preventing cable tangling. During operation, it can also block external forces such as impacts, preventing damage to the cable. The grooves on the side plate 3 provide installation space for the first and second outer ring reinforcing ribs 4 and 5, allowing the reinforcing ribs to be tightly integrated with the side plate 3. Multiple evenly distributed circumferential reinforcing ribs increase the strength of the side plate 3, preventing deformation under radial pressure or other external forces when the cable is entangled. Furthermore, the reinforcing ribs also improve the connection strength between the support cylinder 1 and the side plate 3, making the connection more secure and enhancing the overall stability of the cable reel structure.

[0028] The inner ring 3 of the side plate is located in the same plane as the side plate 3. From the outside to the inside, it has drainage holes 7, positioning holes 8, and support holes 9. The drainage holes 7 and positioning holes 8 are arranged in a circular array. The support hole 9 is located at the center of the inner ring 3, and a support ring 10 is installed inside the support hole 9. The inner ring 3 serves two purposes: firstly, it provides the drainage holes 7, positioning holes 8, and support holes 9; secondly, it enhances the connection strength between the support cylinder 1 and the side plate 3, preventing deformation. The drainage holes 7 are used to drain subsequent surface treatment liquids. During surface treatment of the coil (such as electroplating, spraying, etc.), the treatment... Liquid may remain on the coil. The drain hole 7 allows the treatment liquid to drain smoothly, preventing residual liquid from causing corrosion or other adverse effects on the coil. The positioning hole 8 is used for axial rotation positioning and limiting operations during the operation of the coil. When the coil is installed on relevant equipment, the positioning hole 8 cooperates with the positioning components on the equipment to accurately determine the axial position of the coil, preventing axial movement of the coil during rotation and ensuring the stability of the coil operation. The support hole 9 is used to pass through the support shaft and install the support ring 10, providing an installation position for the support shaft so that the coil can rotate around the support shaft.

[0029] The support ring 10 is installed inside the support hole 9 and is made of steel. Steel has good wear resistance and strength. The support ring 10 can reduce the friction of the support shaft rotation during the operation of the spool. When the spool rotates at high speed, friction will be generated between the support shaft and the support hole 9. As an intermediate component, the support ring 10 can convert sliding friction into smaller friction, reduce energy loss, and at the same time improve the wear resistance and support strength of the spool support hole 9, thus extending the service life of the spool.

[0030] The central shaft 11 passes through the central hole of the inner ring 3 of the two side discs and cooperates with the support hole 9 and the support ring 10. The cooperation between the central shaft 11, the support hole 9 and the support ring 10 further improves the wear resistance and support strength of the support hole 9 of the coil. During the rotation of the support shaft, the central shaft 11 plays a role in further stabilizing the support, making the rotation of the support shaft more stable, reducing vibration and noise caused by unstable support, and improving the operating performance of the coil.

[0031] Magnesium alloy rings are used to connect the left and right support cylinders 1. During the friction stir welding stage, the magnesium alloy rings weld the left and right support cylinders 1 into one piece. Friction stir welding is an efficient and high-quality welding process that can achieve solid-state bonding of metal materials, avoiding defects such as porosity and cracks that occur in traditional fusion welding processes. The use of magnesium alloy rings improves the strength of the weld, making the left and right support cylinders 1 firmly connected, ensuring the integrity and reliability of the overall structure of the coil. Since the density of magnesium alloy is 1.738 g / cm³, which is only 1 / 4 of that of iron and 2 / 3 of that of aluminum, and it has advantages such as high specific strength and specific stiffness, good thermal conductivity, good shock resistance and damping performance, natural heat dissipation and electromagnetic shielding performance, and easy die casting and recycling, the use of magnesium alloy to produce coils can solve the problems of cumbersome processing, heavy weight, easy corrosion, and short lifespan in existing technologies.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
