An Experiential Calculation Method to Radial Extrusion Pressure by Floating-Die

摘要：

By analyzing the rheological behavior and stress to the metal in cross-axle during a radial extrusion with floating-die, establishing a computational model of rigid-perfectly plastic and the stressing model similar to the forward extrusion, and introducing a simple forward extrusion calculation into a complicated radial extrusion calculation, a new calculation for radial extrusion is proposed, then the axial clamping force on female-die and other load parameters are calculated. Through verifying the result by Deform-3D numerical simulation, the formula proposed in this is approved to be of a relatively small error and a high accuracy, which can be applied to various calculations of forward extrusion model.
