Abstract

The invention relates to the forging field, and aims to provide a forging method for a magnesium-alloy automobile hub. The forging method for the magnesium-alloy automobile hub comprises the following steps: step I, heating a magnesium alloy rod in a heating furnace; step II, pre-forging the magnesium alloy rod; step III, carrying out pre-profiling forging on disc-shaped blank; step IV, carrying out fine-profiling forging on a pre-profiled hub; step V, carrying out fine-shaping forging on a fine-profiled hub; step VI, transferring the fine-shaped hub to a transfer table for heating through a position transfer device, wherein a heating temperature is controlled to 320 DEG C to 450 DEG C; and step VII, carrying out rim extrusion sizing on the fine-shaped hub. The forging method for the magnesium-alloy automobile hub is relatively high in production efficiency; and the magnesium-alloy automobile hub is compact in texture, is uniform in component, and is relatively high in mechanical strength.

Description

technical field [0001] The invention relates to the field of forging, in particular to a forging method for a magnesium alloy automobile wheel hub. Background technique [0002] Magnesium alloy materials have the characteristics of light weight, high specific strength, good elastic modulus, good shock absorption and vibration reduction, and can be fully recycled. Using magnesium alloy materials to make automobile hubs is the best wheel hub material after aluminum alloy materials, which can improve the performance of automobiles. Excellent handling performance, acceleration performance and braking performance, and can save fuel by 10% to 14%. The grains of magnesium alloy materials are coarse and the lattice is arranged in a hexagonal square. Deformation; during high-temperature plastic deformation, the temperature range of deformation is narrow, and it is very sensitive to the control requirements of deformation rate and deformation speed; the traditional forming process is ...
