Abstract

The invention relates to a production process of an aluminum alloy anti-collision cross beam with high strength and high plasticity, and belongs to the technical field of aluminum alloy materials. Theproduction process comprises the steps of aluminum ingot preparation, homogenizing treatment, extrusion and aging treatment. In the homogenizing treatment, the temperature is 530 + / -5 DEG C, and heatpreservation is conducted for 3-5 h; and the cooling process after the homogenizing treatment comprises water mist spraying, and the cooling rate is greater than or equal to 350 DEG C / h. According tothe production process, an aluminum ingot is subjected to homogenizing treatment at the temperature of 530 + / -5 DEG C and subjected to heat preservation for 3-5 h, and then water cooling quenching isadopted, so that the hydrogen content in a cast ingot is reduced, the quality of the cast ingot is improved, and then the anti-collision performance of the anti-collision cross beam is improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy materials, and relates to a production process of an aluminum alloy anti-collision beam with high strength and high plasticity. Background technique [0002] The anti-collision beam is a protective component used to reduce the impact of a vehicle during a collision. In the current green and environment-friendly environment, most automobile anti-collision beams are made of aluminum alloy. This puts forward higher requirements on the strength and plasticity of aluminum alloy materials. Most of the existing aluminum alloy anti-collision beams use 6082 aluminum alloy, and its performance reaches RP for ordinary models. 0.2 250~270MPa, Rm280~300MPa and A≥6%, for some special models, its performance can reach RP 0.2 280~310MPa, Rm300~330MPa and A≥10%. However, with the gradual increase in the requirements for automobile safety performance, this performance is difficult to meet people's perfor...
