What should I do if there are cracks on the surface of the die forgings of the suspension hook?

In addition to the surface and the internal surface, there are also different defects. The longitudinal cracks in the forging surface exist in the extension or disturbance, or in the center of the peak near the cap, which is used to form the mold and the inner wall of the new defect. The main reason for the latter is that the pressure is too high when rolling the ingot, and longitudinal scratches occur, In addition, the amount at the cutting end of the die forging is too small, so there is secondary shrinkage of the hole or residual shrinkage hole near the blank mouth end. In addition, the internal longitudinal crack forging is caused by the tension of the central part of the equipment.

Due to the reasonable distribution of metal wires, the yield potential of metal materials can be amplified. Therefore, when important parts of die forgings are used, strict requirements are imposed on the metal flow lines. Through understanding the hot forging process of the aerodynamic distribution part, the design process of improvement measures is proposed. As the aluminum alloy support gasket is used as the support wing of the aircraft, the important parts of the bearing must be closed to improve the mechanical performance of corrosion resistance and fatigue resistance.
