Force Research of Piercing Process in Diescher’s Mill with Mechanical Properties by FEM Simulation

Abstract:

This paper deals with numerical modeling of the piercing process of a thick-walled tube in two rolls skew rolling mill, equipped with Diescher’s guiding discs. After a short description of the problem the numerical model of the process is described. The sensitivity of the simulation results to numerical methods and physical parameters is discussed. The simulated results visualize dynamic evolution of force in the piercing process. The stability of the process and force condition is analyzed by FEM simulation. The model is verified by comparing the values of calculated force parameters and those measured in laboratory conditions. Finally, the future plans are presented.
