RESEARCH STUDIES ON THE ROTARY EXPANSION PROCESS OF PIPES WITH THE HELP OF BRACKET
Aircraft (airplanes, helicopters, missiles, etc.) consists of several thousands of various metal parts, most of them (70 %) was prepared by methods stamping. Widespread use of stamping in aviation and rocket due to a number of its advantages: Low labor intensity; High capacity and low cost of parts; Relatively small losses of the workpiece material, high material utilization; Favorable conditions for the mechanization and automation of processes; High quality of parts (high precision parameters; Small surface roughness, etc.). Depending on the functional parts of the material used, the size and release program uses various methods of manufacture. This distribution processes and crimping pipes, hood, forming and bending of sheet material, etc. For axisymmetric parts such fairing adapter, bellows compensator and other details gidrogazovyh aircraft systems in recent years have increasingly used methods of local deformation, including rotary methods formation, which in comparison with conventional methods stamping possess a number of advantages: reducing the deforming force, simple tooling, forming large opportunities and other benefits. However, not all rotational deformation processes are currently studied sufficiently. This fully applies to the manufacturing process perspective axisymmetric parts of aircraft pipe expansion. Therefore, research in this field are relevant.
