Abstract

The invention relates to a forming and surface treatment method of a twisted waveguide, and belongs to the field of metal additive manufacturing technology and surface treatment. The manufacturing technical problems that parting manufacturing precision and reliability are poor, torsional deformation and position tolerance of torsional forming are not easy to guarantee, and a welding position is prone to deformation are solved, and the problem that a twisted waveguide not plated with a copper layer is large in microwave transmission loss is solved. The method comprises the following steps: modeling a designed twisted waveguide, and completing support adding and slicing processing; aluminum alloy powder is added into a forming equipment material cylinder; performing selective laser melting forming by adopting the slice file to obtain a twisted waveguide with a substrate and a support; separating the twisted waveguide from the substrate and the support; carrying out finishing processing on the twisted waveguide by adopting chemical polishing; and plating the twisted waveguide by adopting chemical plating to obtain the twisted waveguide with the plating layer. The additive manufacturing integrated forming and surface treatment process is adopted, the production period is effectively shortened, the product quality reliability is improved, and the microwave transmission loss is reduced.
