Abstract: Through the optimization of the brazing gap technology of the part into the plow and the fan gold blade,the two-way molding process is used to solved the cracks. The group processing technology of wrinking and grinding the inner and outer ring processing blades to ensure the brazing gap. The two-way forming processing and group blade processing technology are discussed. It is designed to manufacture special forming molds and special tooling with grinding blades to ensure the processing quality of parts, and solve the difficult processing of parts. It meets the design drawing size and assembly requirements of superior components.
