Embodiment 1
[0014] Embodiment 1, a method for forging an aluminum alloy wheel hub, including the following steps, (1) material preparation: using a cast rod whose main material is Al and having a diameter of 254 mm as the base material, and homogenizing the cast rod before blanking, the described In addition to Al, the cast rod also contains the following substances in mass percentage: 0.8% Si, 0.9% Mg, 0.01% Cu, 0.01% Fe, 0.5% Mn, 0.01% Zn, and 0.01% Ti; (2) Cutting: Use a round rod extruder to extrude the homogenized cast rod to a diameter of 203mm. After the extrusion is completed, the extruded rod is obtained, and the extruded rod is sawed into a bar with a weight of 36Kg by a sawing machine. Finally, put it into a heating furnace with a temperature of 460°C to preheat for 2 hours; (3) Forging: Use a pressure forging machine to pre-forge the front of the extruded rod to form a bowl shape, and then use a pressure forging machine to extrude The reverse side of the rod is forged once, fo...

[0015] Embodiment 2, a method for forging an aluminum alloy wheel hub, including the following steps, (1) material preparation: using a cast rod whose main material is Al and having a diameter of 254 mm as the base material, and homogenizing the cast rod before blanking, the described In addition to Al, the cast rod also contains the following substances in mass percentage: 1.0% Si, 1.2% Mg, 0.05% Cu, 0.5% Fe, 0.8% Mn, 0.05% Zn, and 0.15% Ti; (2) Cutting: Use a round rod extruder to extrude the homogenized cast rod to a diameter of 203mm. After the extrusion is completed, the extruded rod is obtained, and the extruded rod is sawed into a bar with a weight of 36Kg by a sawing machine. Finally, put it into a heating furnace with a temperature of 490°C to preheat for 3 hours; (3) Forging: Use a pressure forging machine to pre-forge the front of the extruded rod to form a bowl shape, and then use a pressure forging machine to extrude The reverse side of the rod is forged once, for...
Embodiment 3
[0016] Embodiment 3, a forging method of an aluminum alloy wheel hub, including the following steps, (1) material preparation: using a cast rod whose main material is Al and having a diameter of 254 mm as the base material, and homogenizing the cast rod before blanking, the described In addition to Al, the cast rod also contains the following substances in mass percentage: 0.9% Si, 1.05% Mg, 0.03% Cu, 0.2% Fe, 0.7% Mn, 0.03% Zn, and 0.08% Ti; (2) Cutting: Use a round rod extruder to extrude the homogenized cast rod to a diameter of 203mm. After the extrusion is completed, the extruded rod is obtained, and the extruded rod is sawed into a bar with a weight of 36Kg by a sawing machine. Finally, put it into a heating furnace with a temperature of 475°C to preheat for 2.5 hours; (3) Forging: Use a pressure forging machine to pre-forge the front of the extruded rod to form a bowl shape, and then use a pressure forging machine to extrude The reverse side of the rod is forged once, f...
