Rozov Y.G. Finite element model of the tubular blank drawing on the shaped mandrel in the conical matrix

Abstract

The barrel of the small arms requires great care in the design and production, especially in the internal cavity shaping so called bore. The production of barrels by means of plastic deformation is currently important. However the traditional analytical methods of analysis fail to provide accurate calculations of the critical parameters of the barrel manufacturing processes. This paper presents the computer simulation results of the forming process of the polygonal profile blank inner surface by dragging in a smooth tapered matrix release (centering) of the blank by the caliber of the girdle, using the finite element method.

Keywords

Simulation, dragging, tubular blank, shaped mandrel, barrel, bore, shape.
