Abstract
The invention relates to a corrugated copper clad aluminum bus bar which is produced by coating a corrugated copper layer over an aluminum core and has the manufacturing steps that: an aluminium slab is firstly produced and the cross section of the aluminium slab is elliptic; then a copper strip is gradually coated over the aluminium slab and heat melting welding is conducted on the joint after coating; then a plurality of rounds of elliptic rolls are used for rolling to produce a strip material; and then strip material is drawn into the corrugated copper clad aluminum bus bar product by a die which is provided with corrugation. The technique of the invention has the advantages of simple and easy operation, high efficiency, small investment, low cost, large conducting flow, etc.; the corrugated copper clad aluminum bus bar is a novel energy-saving and environment-friendly material which can entirely replace a pure copper conductor material and has good economic benefits.
Description
Technical field:
The invention belongs to a kind of ripple cuprum-cladding-aluminium bus array in the composition metal conductor.
Background technology:
As everyone knows, natural resources is non-renewable, but the natural resources that has is need constantly consume along with socio-economic development, how in today that the economic development paces are accelerated, the production demand that can rational and effective satisfies environment-friendly products, can save and reduce the consumption of natural resources again, this is the big problem that development in Hi-Tech is faced period.China is the country of the high bauxite resource of poor copper, and the advantage that how to make full use of resource is saved the copper resource, develops aluminium for copper novel high-efficiency and energy-saving material, and for the deposit of copper resource creates conditions, this is imperative, also is that we are making great efforts to realize.
Summary of the invention:
The purpose of this invention is to provide the ripple cuprum-cladding-aluminium bus array and the making thereof in a kind of big capacity current-carrying cross section.
Technical scheme of the present invention is as shown in Figure 1: the copper layer 2 that the band ripple is arranged at the surface coating of aluminium core 1.
Making step of the present invention is as follows:
1 aluminium base: after the aluminium fusion, being cast into a cross section is oval-shaped aluminium blank, scrubs standby;
2 copper strips: the copper strips after will annealing is scrubbed standby by the specification blanking;
3 claddings: standby copper strips by the multiple tracks hybrid mold, is progressively cladded aluminium base top from aluminium base below, joint close, standby;
4 welding: will clad the blank of joint close, and adopt special equipment to carry out sweat soldering, and scrub standby;
5 pressure rollings: will clad the good blank of back welding, and roll through the oval roll of multiple tracks, in the process of rolling, the uniform-compression up and down of blank, plastic deformation moulding and metallurgical atom effectively engage, and are rolled into web;
6 drawings: with the web of making, in being provided with the mould of ripple, the busbar with ripple of all size is made in drawing;
7 check warehouse-ins: the busbar after will completing, after the quality inspection acceptance(check), put in storage.
Advantage of the present invention is: the ripple on the busbar has increased considerably the surface of conductors electric conductivity, makes it to exceed 1.3 times of existing cuprum-cladding-aluminium bus arrays, 1.1 times of the fine copper busbars that exceeds.Temperature rise when having reduced the current-carrying load, guaranteed the long load operation of safety in production, the special thermal treatment of any pollution and extension drawing make it have good tensile strength, flexible and elongation, plasticity helps punching, shearing, bending machining because the present invention's process can not cause environment, in order to guarantee corrosion resistance, can also be a kind of novel conductor material of saving the low power consuming of copper resource, environmental protection, energy efficiency in zinc-plated, silver-plated, the zinc-plated processing of copper laminar surface.
Description of drawings:
Fig. 1: ripple cuprum-cladding-aluminium bus array structural representation
Wherein: 1. aluminium core, 2. copper layer
Embodiment:
The present invention implements by technique scheme and step; the aluminium core can be that fine aluminium also can be an alloy aluminum; about 0.8 millimeter of busbar finished product copper layer thickness; each small echo radius of ripple is 0.5 millimeter, busbar surface area increase by 30～40% approximately; annealing process in manufacturing process is to operate routinely, carries out under inert gas shielding.
The present invention is applicable to the electrical power trans mission/distribution system of electric power, oil, chemical industry, natural gas, metallurgy, mine, light textile, railway electrification, skyscraper industry, be particularly useful for large power plant, power station and electric equipment production industry, also can make outdoor power transmission and transformation system and use.
The present invention is suitable for aforementioned production method, and technology is simple.Easy to operate, the efficient height, small investment, cost is low, and cross section water conservancy diversion amount is big, is a kind of novel conductor material that can replace the energy-conserving and environment-protective of fine copper, and has good economic benefit.
