Description

Technical Field

[0001] The present invention relates to the technical field of waste metal recycling, and particularly relates to a clamping and circumferential cutting device for steel-cored aluminum stranded wire. Background Art

[0002] With the continuous development of the power industry, overhead transmission lines have become an important means of electric energy transmission. As a commonly used overhead transmission conductor, steel-cored aluminum stranded wire (ACSR) is widely used in high-voltage and extra-high-voltage transmission lines. It is composed of an aluminum wire and a steel core. The aluminum wire is mainly used for conducting electricity and undertakes the function of electric energy transmission, while the steel core plays a role in enhancing the mechanical strength of the conductor, being able to withstand mechanical forces such as the conductor's own gravity, wind load, and ice load, ensuring the stability of the transmission line under complex natural environments and operating conditions. In the early stage of power construction, a large number of steel-cored aluminum stranded wires were laid to meet the growing power demand. However, due to technological progress, line upgrading and transformation, natural disaster damage, or other reasons, some of the steel-cored aluminum stranded wires in the transmission lines need to be replaced. Both aluminum and steel are important industrial raw materials and are widely used in many industries such as construction, automotive, and electronics. Recycling aluminum and steel from steel-cored aluminum stranded wire can effectively alleviate the dependence on primary ore resources. For example, recycling aluminum can save a large amount of energy compared to producing primary aluminum from bauxite and reduce the emission of greenhouse gases such as carbon dioxide. If the waste steel-cored aluminum stranded wire is not reasonably recycled, it will occupy a large amount of land space as a landfill. Moreover, in the natural environment, the corrosion of metals will cause the leakage of harmful substances. For example, the corrosion products of aluminum may pollute the soil and water bodies. Since the internal steel core and the external aluminum wire are made of different materials, in order to improve the recycling efficiency, respond to the sustainable development strategy, and avoid environmental pollution and resource waste, it is necessary to separate the steel core from the aluminum wire to improve the recycling efficiency of the steel-cored aluminum stranded wire.

[0003] Early recycling methods mainly involved manual disassembly. Manual disassembly was inefficient, and during the disassembly process, due to the tight bonding between the steel core and the aluminum wire, it was difficult to completely separate them, resulting in a relatively low purity of the recycled metal. With the advancement of technology, some more advanced recycling techniques emerged. For example, chemical separation methods could more effectively separate the steel core and the aluminum wire. By reacting specific chemical reagents with aluminum, the aluminum was dissolved and then recycled, improving the purity of metal recycling. However, chemical separation methods might produce chemical wastewater that needed further treatment to avoid secondary pollution. Another example is that the patent number "CN201721107211.0" disclosed a disassembling and separating machine for steel-cored aluminum stranded wires. This device could only achieve the separation of single-layer aluminum wires through reverse twisting and could not achieve the peeling of multi-layer steel-cored aluminum wires. Moreover, before reverse twisting separation, the steel core and aluminum wire layers at the end still needed to be manually peeled, and true automation was not achieved. Therefore, there is an urgent need to design a steel-cored aluminum stranded wire clamping and circumferential cutting device with a higher degree of automation, especially to achieve the automation of peeling the outer aluminum wire of the steel core and clamping and conveying the steel core. Summary of the Invention
