Industrial material

The profile bending of aircraft landing gear refers to the process of processing metal materials into the required shape by the process of bending. This process is very important in aircraft manufacturing because it ensures the structural strength and stability of the landing gear. The following are some key steps of Beijing Shengda profile bending factory to provide aircraft landing gear profile bending:

1. Material selection: aircraft landing gear needs to bear huge weight and pressure, so it is necessary to use high-strength and high-toughness metal materials, such as aluminum alloy, titanium alloy or steel.

2. Profile cutting: according to the design requirements, cut the metal sheet into the required length and width. This process is usually done using laser cutting or CNC cutting machines.

3. Profile pretreatment: before bending, the profile needs to be pretreated, including the removal of oil stains, rust and oxide scale on the surface, and preheating treatment. Preheating treatment can improve the plasticity of metal materials and reduce the stress and deformation in the process of tension and bending.

4. Stretching and bending molding: put the preprocessed profile into the stretching and bending mold, and apply the tension through hydraulic or mechanical means to make the profile plastic deformation to achieve the required bending Angle and shape. The bending Angle, bending radius and springback need to be strictly controlled to ensure the quality of the landing gear.

5. Post-processing: after forming, the profile needs to be cooled and de-stressed to prevent the deformation of the profile during use. In addition, surface treatment of profiles, such as painting, coating or anodic oxidation, is required to improve their corrosion resistance and aesthetics.

6. Inspection and quality control: in the production process, the size, shape and performance of the profile need to be strictly tested to ensure that it meets the design requirements and standards. In addition, it is also necessary to carry out quality control of the whole tension and bending process to ensure that the quality of the landing gear is stable and reliable.

Beijing Shengda profile bending factory said that in the end, the profile bending of aircraft landing gear is a complex technological process, which requires strict control of each link to ensure the structural strength and stability of the landing gear.
