Abstract


New bimetallic composite wire in one set of two different metal wire material. Due to the characteristics of the high frequency signal current \This article creative design different profiled shape brass casting - cold extrusion process to prepare copper clad aluminum to improve metallurgical bonding of the copper-clad aluminum wire performance. And through a combination of finite element simulation and experimental means forming process, the force in the forming process and forming the microstructure were studied in detail. The paper developed a copper clad aluminum wire forming casting - cold extrusion process, arc-shaped slot, slotted brass design in the form of U-shaped groove, T-slot design, and size structure. On this basis, through the calculation of various parameters of the extrusion, the design of the extrusion molding die. DEFORM finite element analysis software, finite element numerical simulation of cold extrusion process of the copper clad aluminum billet, deformed partition model to establish a bi-metallic material in the extrusion process, the districts of stress and strain in the deformation process, verify the theoretical feasibility of the cold extrusion production of copper clad aluminum wire. Reasonable interpretation of the stress-strain analysis of the grooved area, the design profiled brass shape is more conducive to the realization of the metallurgy of the interface copper and aluminum combined. Copper clad aluminum casting - cold extrusion process, a pilot study of copper clad aluminum cold extrusion deformation process and force, and simulation results were compared to forming a good quality copper clad aluminum products to further verify the feasibility of the process. After extrusion volume thickness of the copper clad aluminum wire products, conductive properties, squeeze pressure, the thinning rate analysis and calculation. Observe and analyze the different deformation stages, different deformation zone microstructure of copper clad aluminum wire, copper clad aluminum extrusion microstructure in the deformation process distribution law, combined with the finite element simulation results, the maximum shear strain theory to explain the distribution pattern of the microstructure. Metallographic experiment with the EDS analysis also combined to determine a good combination of performance copper clad aluminum test product interface.
