EXPERIMENTAL RESEARCH ON ROTARY CRIMP OF PIPES FOR THE PRODUCTION OF DETAILS OF FLYING VEHICLES
The article describes the results of experimental results of rotary crimp. This work performed at the department «Technology of production of aircraft» «MATI» – Russian State Technological University. K.E. Tsiolkovsky, which held all the theoretical and experimental studies. Pipelines operate under complex loading. They are experiencing high pressure, pulsating load and water hammer, so they meet high demands on the mechanical properties of the material, the quality of the external and internal surfaces, preserve cross-sectional shape and the maximum thinning of the pipe wall. Much labor-consuming step in the production process of preparation is linked aircraft to a certain extent that the possibility of the manufacture of components of plastic deformation of the original billet is always limited, both theoretically and in practice are important processing methods that increase the limiting deformation of the workpiece. This leads to a reduction of process steps and transitions, which ultimately reduces the complexity of manufacturing details. Deformation processes must ensure high and stable mechanical properties of the pipe material, high quality internal and external surfaces, the minimum wall thinning and distortion of the pipeline section. Therefore, research in the field of rotary crimp are relevant.
