Numerical modelling of clip manufacturing: focus on the heat treatment

Abstract : Nowadays, manufacturers of clips have to face dimensional problems of their products which are heat treated. By using the numerical approach, companies want to understand reasons of these deformations. Thanks to the modeling of the shaping operation, we obtain the shape and residual stresses of the clip ready for heat treatment. After to have identify thermomecanic parameters used by FORGE2005®TTT on a specific test bench called TABOO, we study the quenching and heating operations. We can so notice that geometrical evolutions are mainly due to residual stresses of bending.
