Influence of Numerical Control Bending Forming Process Parameters on Mechanical Properties of Aerofabrine
The bending angle,bending speed,temperature and other key process parameters of the computer number control bending of the aviation duct were selected.The computer number control bending moment of the aviation duct was analyzed by the bending moment of the elastic deformation zone,the bending moment of the outer plastic deformation zone and the bending moment of the inner plastic deformation zone,and the film pressure of the aviation duct was calculated.The finite element model of computer number control bending of the aviation duct was established according to the calculation results.The reliability of the model is verified.The experimental results show that the bending angle and bending radius have a significant effect on the strength and hardness of the duct.A larger bending angle may lead to a larger deformation,while a smaller bending radius may cause local high stress areas.Selecting the appropriate bending angle and bending radius can ensure the structural integrity of the duct in complex aviation applications.In addition,the molding speed also has a significant effect on the ductility of the conduit material.High-speed forming results in higher strain rates,uneven changes in shape,changes in stress distribution,and a decline in the surface quality of the conduit.By adjusting these process parameters,the hardness of the conduit can be effectively controlled to meet the requirements of material properties in different application scenarios.
