Abstract

In this work, the method of production long-measuring tubular blank (barrel blank) from a short blank by hydrostatic extrusion on the smooth moving mandrel in the high-pressure medium is proposed. We propose the new technologies for receive precision thick-walled tubular blank with inside screw groove
by manufacturing rifled barrel with polygonal section: double-line process, based on crimping barrel blank on the profile mandrel by rolling (wire drawing) idle rollers; pressing-wire drawing of barrel blank with the profile mandrel through the smooth conic mould with the fixation (centering) of blank on parallel land without limitation and with limitation of flow of metal on length. For the first time the method of detection VAT for barrels of small-arms with the inside rifled surface of various shape, situated under the influence of internal static and dynamic loading based on the use of FEM.
