本文对拉拔法制造铝－铜双层金属捧进行了研究。拉拔时，双层金属表面存在速度差，这有利于双层金属的焊合。研究表明增大外管直径和变形程度可明显提高双层金属的焊合强度。通过对焊后双层金属棒的热处理试验，认识了热处理规范对焊合强度的影响规律。通过本文的研究，可以用操作简单、成本低、实用性高的拉拔法获得较高质量的双层金属棒。 In this paper, drawing aluminum-copper double-layer metal holding made research. Drawing, the double-layer metal surface speed difference, which is conducive to double-layer metal welding. The research shows that increasing the diameter and deformation of the outer tube can obviously improve the welding strength of double-layer metal. Through the heat treatment test of the double-layer metal rod after welding, the influence rule of the heat treatment code on the welding strength was realized. Through the research of this paper, we can get higher quality double-layer metal rod by drawing method with simple operation, low cost and high practicability.
