After forging, the temperature of the wheel hub bearing is 920-960 ºC, which is transmitted by the conveyor belt to the mesh belt furnace mouth and forcibly cooled to 500-600 ºC by the centrifugal fan, completing the transformation of pearlite. The microstructure obtained after residual temperature normalization is flaky pearlite and strip-shaped ferrite, with a matrix hardness of 250-265 HBW and a grain size of ≥ 4. Samples were taken from forgings for tensile testing, with a yield strength of 464MPa and a tensile strength of 847MPa
In order to meet the demand for lightweight, the flange plate forgings of wheel hub bearing units tend to have complex product shapes. Traditional manufacturing processes use two steps of upsetting and final forging for forming. However, this design has found that the product flow line, filling effect, and mold life are relatively poor. Therefore, a multi station forming process was proposed: upsetting → forward extrusion → pre forging → final forging → punching
