Embodiment Construction

[0014] The present invention will be further described in detail through specific implementation examples below.

[0015] The preparation process of the high-strength copper-aluminum interface alloy composite busbar in the preferred embodiment of the present invention includes the following steps:

[0016] 1) Clean and brush the inner and outer walls of the copper pipe and the outer surface of the aluminum rod respectively; usually, a cleaning machine and cleaning equipment are used to ultrasonically clean the inner and outer walls of the copper pipe and the outer surface of the aluminum rod, Remove oil, dirt and oxide layers on the surface.

[0017] 2) A drilling machine is used to open a plurality of micro-holes arranged along the axial direction of the copper tube on the outer wall of the copper tube. Specifically, holes are drilled on the outer wall of the copper tube. 1mm; through the automatic casing equipment, the aluminum rod is inserted into the copper tube of the co...

Abstract

The invention discloses a preparation technology of a high strength copper aluminum interface alloy composite busbar, which belongs to the technical field of metal processing. The preparation technology comprises the steps of copper pipe and aluminum rod cleaning, small deformation amount drawing, copper-clad aluminum tube blank high-temperature induction heating through a continuous passing type induction heating furnace and multi-pass continuous rolling. The problems of large copper layer thickness and poor copper layer thickness uniformity in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a preparation process of a high-strength copper-aluminum interface alloy composite busbar. Background technique [0002] Copper-clad aluminum composite busbar is a new type of bimetal composite conductor, which has the advantages of good electrical conductivity, low density and low price. It can replace the existing pure copper conductive busbar and can be widely used in building power distribution busway, high school Frequency heating equipment, various control cabinets and large busbars in the field of metallurgy and chemical industry, etc. In the existing copper-clad aluminum production methods, such as casting method, horizontal continuous casting method, extrusion method, hydrostatic extrusion method, casing drawing method, cladding welding method and rolling crimping method, it is difficult to prepare the cross-sectional size High-performance copper-aluminum compo...
