The invention relates to the technical field of automobile anti-collision beams, and particularly discloses a
processing technology of an automobile high-strength and high-performance aluminum
alloy anti-collision beam, which comprises the following steps: step 1,
smelting:
smelting industrial pure aluminum to a
liquid state, stirring, sequentially adding Cu, Mn and Cr metals, stirring again, adding Si, Zn and Mg metals, continuously stirring, and adding RE and Ti to obtain a melt; step 2,
casting: a semi-
continuous casting method is adopted, the melt is placed in a
casting mold for shaping, and a
casting rod is obtained; step 3, homogenizing: loading the cast rod into a soaking pit furnace, heating to 515-535 DEG C, preserving heat for 8-10 hours, slowly cooling to below 200 DEG C along with the furnace, discharging and
air cooling, and eliminating casting stress and component segregation; on the basis of existing 6-series aluminum
alloy components, the
mass fraction of each chemical component in the aluminum
alloy raw material is readjusted, so that 6-series products meeting 7-series performance standards are processed, key performance indexes such as tensile strength, yield strength,
ductility and elasticity modulus of the anti-collision beam are greatly improved, the process cost is reduced, and the production efficiency is improved. Efficient production and
processing of enterprises are facilitated, and the purpose of
thinning and weight reduction of the anti-collision beam is achieved.
