Abstract：

The barrel is an important part of the artillery and automatic weapons. Radial forging is a new method for manufacturing barrel. Compared with the traditional tube processing, the barrel manufactured by radial forging has higher intensity and longer life, also the material can be saved. For radial forging of a barrel, the three dimensional model of barrel was established by 3D software SolidWorks and the deformation of barrel was numerically simulated by the metal plastic forming finite element software Deform during the radial forging process. Furthermore, the material flow was analyzed when the rifling was formed and verified by test. The test results show that when the material is deformed by forging, a neutral surface exists, and the metal materials on both sides of the neutral plane generate deformation in both radial and axial directions. So they are in agreement with the simulation results.
