At present, mould flanging forming is mostly adopted for flanging forming of the wind protection ring, but the mould flanging forming has more defects. Firstly, the weight of the forming die is far more than that of the wind-guard ring, and the forming dies corresponding to the wind-guard rings with the same cross section and different diameters are different, so that the forming die cannot be used universally. Secondly, because the forming resilience is difficult to control due to the difference of the materials of the wind-guard ring, the flanging forming precision of the wind-guard ring is improved only by a method of die testing and die repairing or a method of adding a shaping process, so that the processing efficiency is low. Thirdly, the radial positioning of the flanging forming die is mostly a fixed value, and the deviation of the diameter of the inner hole of the wind protection ring cannot be compensated, so that the flanging forming may have an eccentric phenomenon. Finally, the flanging forming of the die easily causes serious strain marks on the surface of the wind-protecting ring and also easily causes tensile cracks on welding seams, in particular to the light aluminum alloy wind-protecting ring.
