Embodiment 1
[0075] This embodiment illustrates the present invention by taking the forging process from the initial blank to the forging of the front landing gear outer cylinder of the aircraft as an example. The material of the forging is 300M steel. figure 1 Shown is a flow chart of a method for hot forging an aircraft nose landing gear outer cylinder based on gradient induction heating.
[0076] 1. The shape of the outer cylinder forging of the front landing gear of the aircraft is as follows: figure 2 shown. According to the theory of plastic deformation volume invariance, considering the flash size, combined with the existing blank design method, the design and processing are as follows: image 3 Initial blanks shown. And design the corresponding mold according to the target forging shape and size, and the mold material is 5CrMnMo. Since the method of designing the initial blank and mold according to the shape and size of the part is very mature, I will not repeat it here.
