Numerical simulation of hot forging process in production of axisymmetric automobile parts

Abstract

The fin ite element method were used for the plastic metal flo w predict ion of ring shaped parts. Various parameters that affect the forging operation are the material characteristics like material strength, ductility, deformat ion rate, temperature sensitivity and frict ional characteristics of the workp iece, prefo rm design, die design and die material. Nu merical simulat ion has been done for axisy mmetric automobile parts. The procedure of nu merical modeling contains all simulat ions phases like the movement of p reform fro m inductor to the tool, placement and setting of preform piece inside the tool before the blow in order to get as good result as possible. These techniques are used to reduce the amount of input material for forgings, extend the lifetime of fo rging dies, and prevent defects in forged components.

Development and optimization of technology and modernization of forging line for bearing rings

“…The statement of the associated problem of induction heating and plastic deformation of a cylindrical workpiece was considered by the authors in [11]. Mathematical modeling of pressure treatment of axisymmetric (cylindrical) parts during three-stage shaping is considered in [12]. The methodology for modeling wear of die tooling taking into account the thermal effect on the material of the die is described in [13].…”

Calculation of the Plastic Metal Flow in the Cold Extrusion Technology by Finite Volume Method

“…Two different approaches, namely the "flow approach" (flow formulation) and "solid approach", have emerged for the simulation of metal forming processes using different numerical methods [1,2], mainly the finite element method (FEM), [1,[3][4][5] and recently the finite volume method (FVM) [6][7][8][9].…”
