Elastic-Plastic Finite Element Analysis on Steel Pipe Rotary-Draw Bending Process

Abstract:

With non-linear elastic-plastic finite element method, the numerical simulation of the steel pipe rotary-drawing bending process is carried out, and the forming mechanism and spring-back phenomenon of rotary-draw bending is analyzed. Aiming at the phenomenon of pipe collapse deformation, a mandrel is used and it makes the bending process. The simulation results show that using mandrel could avoid collapse appearing in deformation area, reducing contact friction coefficient will help to improve wall thickness uniformity, and increasing the angle of rotary-draw bending will aggravate the amount of spring-back.
