1. The materials used in
Aerospace Micro Screws should not only meet the technical requirements of product design, but also meet the requirements of stamping process and post-stamping processing requirements (such as cutting, electroplating, welding, etc.).
2. When designing the structural shape of parts of Aerospace
Micro Screws, it is best to use simple and reasonable surfaces (such as planes, cylindrical surfaces, spiral surfaces) and their combinations. At the same time, the number of processed surfaces and the processing area should be minimized as much as possible.
3. Choose a reasonable method for preparing blanks in mechanical manufacturing, which can directly use profiles, casting, forging, stamping and welding. The selection of blanks is related to specific production technical conditions, generally depending on production batches, material properties and processing possibilities.
4. Requirements for metal stamping forming performance. For the forming process, in order to facilitate stamping deformation and improve the quality of parts, the material should have good plasticity, small yield strength ratio, large plate thickness directional coefficient, small plate plane directional coefficient, and a small ratio of the material's yield strength to elastic modulus. For the separation process, the material does not need to have good plasticity, but it should have a certain plasticity. The better the plasticity of the material, the less easy it is to separate.
5. Specify the appropriate manufacturing accuracy and surface roughness of the parts processing costs. The processing costs of Aerospace Micro Screws will increase with the improvement of accuracy, especially in the case of high accuracy, this increase is very significant. Therefore, high accuracy should not be pursued without sufficient basis. Similarly, the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface.
