Abstract
Manufacture of long hollow parts specified internal profile of the hard-deformable alloys based on process improvement of cold deformation of a tubular workpiece requires the development of science-based modes of technology to assure the quality of products, reduction of the complexity of manufacturing, steel intensity etc. Stress-strain state and energy-power parameters of the rolling-drawing process non-driven roller tubular billet on the profile mandrel is define by computer analysis that have been made. The shape and dimensions of mandrel corresponded to the inner surface of the rifle barrel with the polygon profile type. As a result, it has been developed and manufactured the corresponding technological device and has been manufactured the product by above method.
