Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal rod processing technology, and in particular to a high-strength, anti-oxidation copper rod. Background Technology
[0002] Copper rods are widely used in power transmission, electrical equipment, heat exchange systems and precision machinery due to their excellent electrical and thermal conductivity, and are an indispensable basic material in industrial production.
[0003] With technological advancements, the application scenarios for copper rods are becoming increasingly demanding. In many high-end equipment or special working conditions, such as serving as high-load structural connectors or high-current busbars, copper rods not only need to withstand enormous mechanical stresses but are also frequently exposed to humid, high-temperature, or corrosive gas environments. This places dual high-performance requirements on them: they must possess sufficient mechanical strength to resist external forces such as bending and stretching, and also have excellent oxidation resistance to prevent surface corrosion that could lead to performance degradation and shortened lifespan.
[0004] To address these challenges, existing technologies typically employ two independent approaches. One is to enhance the strength of the copper matrix through alloying, but this method often sacrifices copper's original high conductivity and has limited effect on improving oxidation resistance. The other approach involves surface protection treatments on ordinary copper rods, such as electroplating with tin or nickel, or coating with organic coatings. While these can isolate oxidation to some extent, these protective layers are usually quite fragile. When the copper rod is subjected to significant mechanical stress and undergoes minor deformation, problems such as cracking and peeling can easily occur, thus losing their protective effect and failing to meet the combined requirements of high strength and oxidation resistance.
[0005] Therefore, this invention proposes a high-strength, anti-oxidation copper rod to address the shortcomings of existing technologies. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a high-strength, anti-oxidation copper rod, which aims to improve the problem that copper rods in the prior art are prone to deformation or breakage due to insufficient mechanical strength when applied to high-stress and easily oxidized working conditions, and that poor oxidation resistance leads to a shortened service life.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength anti-oxidation copper rod, comprising: a copper core, a reinforcing component, and an anti-oxidation component, wherein the reinforcing component is fixedly connected to the outer periphery of the copper core, and the reinforcing component comprises multiple longitudinal reinforcing ribs distributed along the axial direction of the copper core, and transverse reinforcing ribs connected to the multiple longitudinal reinforcing ribs;
[0008] The antioxidant component includes a ceramic coating formed on the outer surface of the reinforcing component and a convex ring fixedly connected to the end of the high-strength antioxidant copper rod. The outer surface of the ceramic coating is provided with a spiral groove, and the inner wall of the convex ring is assembled by abutting against the outer periphery of the end of the ceramic coating.
[0009] Preferably, the multiple longitudinal reinforcing ribs are evenly spaced along the circumference of the copper core.
[0010] Preferably, the transverse reinforcing ribs surround the circumference of the copper core.
[0011] Preferably, the connection between the transverse reinforcing rib and the longitudinal reinforcing rib is an integrally formed structure.
[0012] Preferably, the ceramic coating fills the space between two adjacent longitudinal stiffeners and covers both the longitudinal stiffeners and the transverse stiffeners.
[0013] Preferably, the spiral groove is a groove that extends continuously along the axial direction of the ceramic coating.
[0014] Preferably, the outer diameter of the convex ring is larger than the outer diameter formed by the ceramic coating.
[0015] Preferably, both ends of the high-strength anti-oxidation copper rod are provided with the convex ring.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model solves the problem of insufficient mechanical strength of ordinary copper rods in the prior art, which makes them prone to bending or breaking under high stress conditions, by setting a reinforcing component consisting of interconnected longitudinal and transverse reinforcing ribs on the outside of the copper core. This achieves the effect of significantly improving the overall structural strength and deformation resistance of the copper rod.
[0018] 2. This utility model solves the problem of the single anti-oxidation protection method for copper rods in the prior art, which is not effective in key areas such as humid environments or connection parts, by setting up a multi-layered anti-oxidation component composed of ceramic coating, spiral groove and convex ring. It achieves a comprehensive and highly reliable anti-oxidation effect that combines physical isolation, liquid drainage and end sealing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-3 The present invention provides an embodiment of a high-strength anti-oxidation copper rod, comprising a copper core 1, a reinforcing component 2 for enhancing structural strength, and an anti-oxidation component 3 for providing anti-oxidation protection, the three components working together to form a complete composite structure.
[0026] Specifically, the reinforcing component 2 is fixedly connected to the outer periphery of the copper core 1. The reinforcing component 2 includes multiple longitudinal reinforcing ribs 201 distributed along the axial direction of the copper core 1, and transverse reinforcing ribs 202 connected to the multiple longitudinal reinforcing ribs 201. The multiple longitudinal reinforcing ribs 201 are evenly spaced along the circumference of the copper core 1. Each longitudinal reinforcing rib 201 extends along the length of the copper core 1. The transverse reinforcing ribs 202 surround the circumference of the copper core 1 and fix all the longitudinal reinforcing ribs 201 to each other, thereby forming an integral grid skeleton structure on the outside of the copper core 1. In a preferred embodiment, the transverse reinforcing ribs 202 and the longitudinal reinforcing ribs 201 are integrally formed at their respective connection points, ensuring the structural stability of the reinforcing component 2 itself.
[0027] Antioxidant component 3 covers the outer surface of the assembly formed by reinforcing component 2 and copper core 1. Antioxidant component 3 includes a ceramic coating 301 formed on the outermost layer, a spiral groove 302 formed on the outer surface of ceramic coating 301, and a convex ring 303 set at the end of high-strength antioxidant copper rod. The ceramic coating 301 fills the space between two adjacent longitudinal reinforcing ribs 201 and completely covers the exposed surfaces of all longitudinal reinforcing ribs 201 and transverse reinforcing ribs 202, thus forming a continuous and dense physical isolation layer. The spiral groove 302 is a groove structure that extends continuously along the axial direction of ceramic coating 301. The convex ring 303 is fixedly connected to the end of high-strength antioxidant copper rod. Convex rings 303 are provided at both ends of high-strength antioxidant copper rod to form a symmetrical end protection structure. The inner wall of each convex ring 303 abuts against the outer periphery of the end of ceramic coating 301, forming an effective limiting protection for the end of ceramic coating 301. At the same time, the outer diameter of the convex ring 303 is larger than the outer diameter formed by ceramic coating 301.
[0028] The overall structure of the reinforcing component 2 is a grid skeleton fixedly connected to the outer periphery of the copper core 1. The reinforcing component 2 is composed of multiple longitudinal reinforcing ribs 201 and multiple transverse reinforcing ribs 202. The multiple longitudinal reinforcing ribs 201 are evenly spaced along the circumference of the copper core 1, and the length direction of each longitudinal reinforcing rib 201 is consistent with the axial direction of the copper core 1. The transverse reinforcing ribs 202 surround the circumference of the copper core 1, and the transverse reinforcing ribs 202 connect all the longitudinal reinforcing ribs 201 radially outward, thereby forming a high-strength support whole. The setting of the reinforcing component 2 provides the copper core 1 with dual mechanical support in both the axial and radial directions.
[0029] The antioxidant component 3, based on the reinforcing component 2, constructs a multi-layered protective structure. The ceramic coating 301 of the antioxidant component 3 not only covers the outer surface of the reinforcing component 2, but also fills all the gaps between two adjacent longitudinal reinforcing ribs 201 and between the transverse reinforcing ribs 202 and the copper core 1, so that the ceramic coating 301 forms a seamless and tight bond with the copper core 1 and the reinforcing component 2. A spiral groove 302 is also processed on the outer peripheral surface of the ceramic coating 301. The spiral groove 302 is a groove that extends continuously along the axial direction of the ceramic coating 301, which is used to extend the intrusion path of external media and guide the liquid out. At the end of the high-strength antioxidant copper rod, a convex ring 303 is also provided. The inner wall of the convex ring 303 abuts against the outer peripheral surface of the end of the ceramic coating 301, and the outer diameter of the convex ring 303 is larger than the outer diameter of the ceramic coating 301. The convex ring 303 plays a role in limiting and physically protecting the end of the ceramic coating 301.
[0030] To make the supporting force provided by the reinforcing component 2 to the copper core 1 more balanced and stable, multiple longitudinal reinforcing ribs 201 are arranged in an array with uniform intervals along the circumference of the copper core 1, and transverse reinforcing ribs 202 are arranged in a ring and surround the circumference of the copper core 1. The transverse reinforcing ribs 202 connect all the uniformly spaced longitudinal reinforcing ribs 201 from the outer periphery to form a cage-like integral structure. In order to maximize the structural strength and integrity of the reinforcing component 2, the transverse reinforcing ribs 202 and the longitudinal reinforcing ribs 201 are manufactured by integral molding at all connection nodes, thereby eliminating potential structural weaknesses caused by weak connections.
[0031] In order to achieve a complete physical isolation protection between the copper core 1 and the reinforcing component 2, the ceramic coating 301 not only covers the exposed surface of the reinforcing component 2, but also completely fills the radial space between all adjacent longitudinal reinforcing ribs 201. Furthermore, the ceramic coating 301 completely covers the longitudinal reinforcing ribs 201 and the transverse reinforcing ribs 202, forming a dense composite protective layer without internal gaps.
[0032] The spiral groove 302 is a single-headed or multi-headed spiral groove that extends continuously along the axial direction of the high-strength anti-oxidation copper rod on the outer cylindrical surface of the ceramic coating 301. In order to provide consistent protection and convenient installation and docking, both ends of the high-strength anti-oxidation copper rod are fixedly connected with convex rings 303 to form a symmetrical end structure. In order to prioritize the protection of the edge of the ceramic coating 301 from damage when the copper rod collides or docks with other components, the outer diameter of each convex ring 303 is larger than the maximum outer diameter formed by the ceramic coating 301 itself, so that the convex ring 303 becomes the outermost contact point.
[0033] Working Principle: This high-strength, anti-oxidation copper rod achieves both high strength and anti-oxidation properties through the synergistic structure of the copper core 1, reinforcing components 2, and anti-oxidation components 3. The copper core 1 bears the basic load-bearing and electrical conductivity functions. The reinforcing components 2 provide mechanical strength enhancement to the copper core 1 through their grid skeleton structure. Among them, the longitudinal reinforcing ribs 201 distributed along the axial direction of the copper core 1 provide axial support force to improve the copper core 1's resistance to bending and tension in the axial direction. The transverse reinforcing ribs 202 surrounding the copper core 1 connect the longitudinal reinforcing ribs 201 into a stable whole, allowing the support force provided by the longitudinal reinforcing ribs 201 to be more evenly distributed on the copper core 1, thereby significantly enhancing the overall structural strength of the copper core 1 and preventing the copper core 1 from deforming or breaking due to external high-intensity stress.
[0034] The anti-oxidation component 3 provides comprehensive anti-oxidation protection for the copper core 1 and the reinforcing component 2. The ceramic coating 301 covers and fills the outside of the copper core 1 and the reinforcing component 2, forming a dense physical barrier that directly blocks the contact between external oxidizing media such as oxygen and water vapor and the copper core 1. The spiral groove 302 on the outer surface of the ceramic coating 301 increases the path length for the oxidizing media to contact the copper core 1, and effectively guides the liquid adhering to the surface to flow along the spiral groove 302 and drain out, reducing the residence time of the liquid on the surface of the copper rod. The convex rings 303 set at both ends of the copper rod have their inner walls abutting against the ends of the ceramic coating 301, providing effective physical restraint and protection for the vulnerable coating edges. At the same time, when the copper rod is connected to other components, the convex rings 303, due to their structure with an outer diameter larger than that of the ceramic coating 301, can reduce the chance of oxidizing media penetrating into the connection gap, further enhancing the anti-oxidation protection effect on the copper core 1.
