An overall manufacturing method for a large-sized, thin-walled annular oxygen reinforced frame, comprising the following steps: designing a special substrate for laser melting deposition; by segmenting the oxygen reinforced frame up and down along the sudden change of wall thickness, selecting a laser with higher power and higher scanning speed Fusion deposition process parameters and corresponding scanning strategies are used to shape the lower part, and then the laser processing program codes of the upper and lower slicing layers are obtained with the help of slicing software. The equipment is imported to first perform laser fusion deposition forming of the lower part, take out and then perform stress relief annealing, and then the lower end face To complete the deposition of the upper part of the base, the final state parts are obtained by subsequent heat treatment and machining, which solves the problems of long processing cycle, low material utilization rate and serious stress deformation in the current forging + machining method, and realizes the oxygen reinforced frame parts. High-performance, small deformation, small margin forming. |
