The production process adopts the processes of specification setting, raw material selection, rolling parameter setting, variable-thickness rolling, straightening shearing and blanking, further gives consideration to high strength and weight reduction on the basis of thermal forming of an aluminum-silicon plate, makes up for the complexity and defects of an aluminum-silicon plate tailor welding process, and produces the aluminum-silicon variable-thickness plate and a special-shaped aluminum-silicon variable-thickness plate with good performance for thermal forming, the using performance of automobile inner plate structural parts and safety parts can be met, and perfect combination of material lightweight and structural lightweight is achieved.

Description

technical field [0001] The invention belongs to the thickening plate rolling technology, and in particular relates to a production process of an aluminum-silicon thickening plate for thermoforming. Background technique [0002] The general trend of today's automotive technology development is energy saving, environmental protection, safety, comfort, intelligence and networking. Reducing fuel consumption and reducing emissions under the premise of ensuring performance is one of the problems that need to be solved urgently in today's automotive field. An important way to solve this problem has become the mainstream of modern automobile design and manufacture; considering that the mass of the automobile body accounts for about 30-40% of the total weight of the automobile, and the weight of the automobile is reduced by 100 kg, at least 0.6L can be saved per 100 kilometers Fuel can reduce 5g of CO2 emissions per kilometer; therefore, the weight reduction of the body is very impor...
