Abstract: |
Aiming for the problems of technology of cold roll bending thin-walled tube-shaped titanium alloy parts with small curvature radius, the research contents included theoretical calculation, FEA, design and trial production of the bending machine, as well as process test. The test result indicated that the quantity of the tube-shaped parts, produced by the bending machine, can meet the requirement of automatic welding. This research result has been successfully used in the manufacture of aerospace products. This technology is high quality, efficiency, and green machining. |
