背景技术 Background technique
众所周知， 铜包铝线和铜包铝管是铜铝复合材料， 是上述产品具备铝的质 量轻， 同时又具备铜的导电性， 防腐性能好的优点， 广泛应用在射频电缆， 电 磁线， 编铝屏蔽线， 电源线等产品上。 降低成本， 节约资源。 铜包铝管即可用 于射频电缆的悬线， 又可用于空调等产品做冷凝管用， 铜包铝产品是新型的替 代铜、 铝的最佳， 最有发展前途的产品。 由于世界铜资源的匮乏， 世界经济发 展需求量越来越大， 目前铜价飞速上涨， 寻找最佳的铜铝复合材料替代纯铜是 当前燃眉之急， 也是形势上的需求。 然而目前生产铜包铝线是传统的力变形技 术。 轧压法生产铜包铝线用两侧的铜带同时包夹住铝芯线通过轧机在氩气保护 环境轧压而成， 在压力之下， 两者之间实现治金结合， 再经铣削机将对接处的 铜边铣掉即成毛坯铜包铝线， 还得另经拉伸机进行多次拉拔和热处理工序之后 才成为铜包铝线成品， 所述的方法尽管能生产铜包铝坯线， 但是仍存在着只适 于生产小线径的坯线， 若生产大线径的坯线明显暴露出铜材料用率低、 外层铜 带均匀性不理想的缺点； 又如包覆焊接将一纯铜带通过逐级变成圆管状把铝芯 杆包于其内， 在惰性气体保护下进行自动焊接， 再经精整和缠绕完成铜包铝坯 线生产， 随后再经多次拉拔和热处理工序成为铜包铝线成品。 该方法生产的铜 包铝线虽然具有铜层均匀性好， 节省铜材， 生产速度较快的优点。 但是也存在 着诸如焊接后需经过多次拉伸才能达到治金结合不仅费工耗时加大生产成本。
而且因其拉伸模压次数多表面易损伤等不如人意之缺陷。 特别是其总变形量达 到 87%以上才能达到以治金结合的要求， 因此达到冶金结合之前的拉伸质量很 难控制， 给拉伸工艺增加了难度。 如不能尽快解决将会影响铜包铝线的质量稳 定性， 这已引起业内相关人士的严重关注， 并投入科技人员和财力， 但是目前 尚未见到成功解决的相关报导。 As we all know, copper clad aluminum wire and copper clad aluminum pipe are copper-aluminum composite materials. These products have the advantages of light aluminum, copper conductivity and corrosion resistance. They are widely used in RF cables, electromagnetic wires, and Aluminum shielded wire, power cord and other products. Reduce costs and save resources. The copper-clad aluminum tube can be used for the suspension cable of the RF cable, and can also be used for the air conditioning and other products for the condensation tube. The copper-clad aluminum product is the best alternative to copper and aluminum, and the most promising product. Due to the shortage of copper resources in the world, the demand for world economic development is increasing. At present, the price of copper is rising rapidly. Finding the best copper-aluminum composite material instead of pure copper is the urgent need, and it is also the demand in the situation. However, the current production of copper clad aluminum wire is a traditional force deformation technology. The copper-clad aluminum wire produced by the rolling method is formed by clamping the aluminum core wire at the same time and clamping the aluminum core wire through the rolling mill in an argon-protected environment. Under pressure, the metallurgical combination is realized, and then the milling is performed. The machine cuts the copper edge of the butt joint into a blank copper clad aluminum wire, and has to be subjected to multiple drawing and heat treatment processes by a stretching machine to become a copper clad aluminum wire finished product, although the method can produce a copper clad. Aluminum blank, but there are still blanks that are only suitable for the production of small diameters. If large diameters are produced, the blanks are obviously exposed to the disadvantages of low copper material and unsatisfactory uniformity of the outer copper strip. Over-welding, a pure copper strip is wrapped into a round tubular shape, and the aluminum core rod is wrapped therein, and is automatically welded under the protection of an inert gas, and then the copper-clad aluminum blank is produced by finishing and winding, and then The secondary drawing and heat treatment process becomes a finished copper clad aluminum wire. The copper-clad aluminum wire produced by the method has the advantages of good uniformity of the copper layer, saving copper material and high production speed. However, there are also cases in which, after welding, it is necessary to undergo multiple stretching to achieve the combination of the metallurgy, which not only takes time and labor, but also increases the production cost. Moreover, due to the number of times of stretching and molding, the surface is easily damaged and the like is not satisfactory. In particular, the total deformation amount of 87% or more can meet the requirements of the combination of metallurgy, so the tensile quality before metallurgical bonding is difficult to control, which increases the difficulty of the stretching process. If it can't be solved as soon as possible, it will affect the quality stability of the copper clad aluminum wire. This has caused serious concern of the relevant people in the industry, and invested in scientific and technical personnel and financial resources, but no relevant reports have been successfully resolved.
