An aluminum alloy strip for continuous deep drawing processing of small metal stamping parts and its preparation method

Abstract

The invention relates to an aluminum alloy strip for continuous deep drawing processing of small metal stamping parts and a preparation method thereof. In terms of mass percentage, the aluminum alloy strip is composed of the following components: 0.5-3.5% Mg, 0.05-1.0% X, 0.05-0.5% Ti, the balance is Al and unavoidable impurities, the total amount of impurity elements <0.08%; the X is any 2 of Cu, Y, V, Ce, La or Be one or a combination of three. In the present invention, an aluminum alloy strip with a thickness of <0.35 mm is prepared through reasonable selection and optimized design of alloying elements, and through secondary smelting and periodical mechanical vibration of the mold during alloy solidification, followed by calendering . The obtained strip has excellent plasticity and deep-drawing forming properties, can meet the requirements of continuous deep-drawing processing of small metal stamping parts, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal processing, in particular to an aluminum alloy strip for continuous deep drawing processing of small metal stamping parts and a preparation method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Due to the advantages of small specific gravity, high strength, good plasticity, excellent stamping performance, corrosion resistance and easy coloring, aluminum alloys are widely used in the field of stamping and forming. [0003] Stamping is a high-efficiency processing technology that can directly form rolled plates and strips with excellent performance. It has great market advantages and development prospects. Deep drawing refers to the metal plastic processing method in which metal sheets ar...

Problems solved by technology

In addition, the current research on the deep drawing performance of aluminum alloys is mostly concentrated on aluminum alloy strips with a thickness of more than 0.5mm, and there are few studies on aluminum alloy strips with a thickness of less than 0.35mm.

CN107739924A discloses an aluminum alloy strip for a vacuum booster shell of a new energy vehicle and a preparation method thereof. The aluminum alloy strip prepared by the strip has high strength and good formability, and can meet the three-time deep drawing and two-time turning requirements of the vacuum booster shell. The stamping and forming process requirements of the edge, but the thickness of the aluminum alloy finished strip of the patent is much greater than 0.35mm

CN106834825A discloses a kind of 5182 aluminum alloy and the process method that this aluminum alloy is prepared into can lid material strip, and its preparation has obtained the aluminum alloy that thickness is 0.29mm, but the obtained finished aluminum alloy strip has high strength, but plasticity is very low, The elongation is only 4-6%, not suitable for multi-pass deep drawing

CN108004435A discloses an improved CTP plate-based aluminum alloy strip based on No. 1052 aluminum alloy. Through processes such as melting, thinning, casting and rolling, finishing rolling, stretch bending and straightening, an aluminum alloy plate with a thickness of 0.28mm is produced. Although the elongation rate of the obtained sheet has reached 20-30%, its strength is insufficient, and the deep drawing performance is not good, and it is also difficult to meet the process performance requirements of continuous deep drawing and the product requirements that require higher strength.
