FEM-Based Analysis on the Process of Tube Stamping

Abstract

Pipe stamping processing is a new kind of processing method ,which is high efficiency, low cost, low energy consumption .It has the very high practical value. Aiming at the tube punching force and deformation characteristics, the application of plastic finite element method was used to study the tube punching main process parameters on forming after the influence of wall collapse. Research shows that: wall collapse as tool feed speed increases first increases, then decreases to a certain degree; Along with the fixed die mandrel increases ; With the increase of the wall inside diameter increases.
