[0002] A nacelle refers to a streamlined short nacelle section equipped with certain airborne equipment and suspended under the fuselage or wing. The U-shaped aluminum alloy casting is the main component of the nacelle, assembled in the middle position, mainly playing the roles of protecting, supporting and fixing internal components. The casting accuracy of the whole component directly affects the machining accuracy of the product, thus affecting the performance, accuracy and service life of the nacelle.

[0003] The co-ends of the U-shaped aluminum alloy parts are connected, and the two arms extend downward or upward. The wall thickness of the two arms is only 4-5 mm. During the casting and heat treatment processes, due to its structural characteristics, the platen-like structure of the two arms is prone to diverge and deform outward, affecting the dimensional accuracy of the machined parts and having an impact on the assembly. After solution treatment, shaping is required.

[0004] The traditional shaping process is carried out by skilled workers using a wooden hammer or a rubber hammer to strike the casting. The manual shaping efficiency is low and the shaping effect is not obvious. Moreover, the process of manual shaping is uncontrollable, and the stress degree of the casting cannot be controlled, affecting the size and structure of the casting, resulting in problems such as out-of-tolerance dimensions and cracks.
