The technical scheme is that and be achieved in that: a kind of copper cover aluminum is combined the preparation technology of V-type line, first it is combined into copper cover aluminum complex by core aluminum and clad copper, its blank uses horizontal casting direct combination manufacturing process to make, coated copper layer area ratio is 15～50%, comprises the steps:
(1), rolling: for the cogging method that cross section is band corner square blank be: blank length of side 43-45mm, groove rolling 11 passage, mill speed 10～40m/min, flat-rolled, rolling on edge circulates successively, every time deflection 10～40%, rolling cross section total deformation is 70～80%, is closely sized to 20mm × 15mm；
(2), drawing: drawing speed controls to 2～35 m/min, four passages of drawing, after first passage drawing, sectional dimension is about 20mm × 15mm, and three passage area reduction amounts control to the area reduction amount that 15～25%, four passages are total to control to 40～50% subsequently；
(3), flat-rolled: flat-rolled a time, mill speed is 10～40m/min, and drafts 1～3mm rolls rear size, slightly larger than abnormity drawing mould size；
(4), V-type drawing: drawing speed controls to 2～35 m/min, and single pass area reduction is 10～20%, to qualified size.
Preferably, comprise the steps:
(1), rolling: be the foursquare blank cogging method with corner for cross section: billet size about 44mm × 44mm, with groove rolling, mill speed scope is 10～40m/min, previous three passes, successively flat-rolled, rolling on edge, flat-rolled, and drafts is 20～35%；Middle three passages respectively deflection is 10～the rolling on edge of 20%, flat-rolled, rolling on edge；Carrying out flat-rolled, rolling on edge the most successively, drafts is 25～40% to close to 20mm × 15mm size；
(2), drawing: drawing speed controls to 2～35 m/min, first drawing makes width reduction amount control to 3～6mm, reduced down in thickness amount 2～4mm, and after drawing, size is about 20mm × 15mm, second drawing reduced down in thickness amount controls to 2～4mm, and width reduction amount controls to 1～3mm；Proceeding two passage drawings, width decrement is 2～4mm, and thickness decrement is 1～3mm, and after drawing, area reduction amount is 40～50%；
(3), flat-rolled: mill speed is 10～40m/min, drafts 1～3mm, rolls rear size, slightly larger than abnormity drawing mould size；
(4), V-type drawing: drawing speed controls to 2～35 m/min, width decrement 2～4mm, and thickness decrement 1～3mm, to qualified size.
The invention has the beneficial effects as follows: based on horizontal casting direct combination forming technology, designed, designed drawing die pass and join mould, technological parameter, use abnormity drawing mould, solve other copper-coated aluminium composite material technologies of preparing and be difficult to V-type wire rod and a size-constrained difficult problem, the copper layer thickness that copper cover aluminum prepared by the present invention is combined V-type wire rod is adjustable, bond strength is high, any surface finish, dimensional accuracy is high, mechanical property meets the requirements, and process efficiency is high, generalization is strong, by appropriate design technological process, drawing mould, rolling groove, the special-shaped copper alclad compound section of other cross sectional shapes can be prepared.
