Design and manufacturing procedure for cold stamped metal components.

摘要

Design and manufacturing process of cold-stamped metal components, comprising: # - characterization tests of the material (410) of the component under delivery conditions; # - Marciniak drawing tests (432) to extract deformation measurements and elasto- parameters plastics of the material; # - simulation of drawing tests (440), obtaining an objective structural model (464), # - reverse drawing simulations (450), obtaining a source model (466) with estimation of deformations and thickness changes in the drawing; # - mapping (462) of the deformation results of the source model (466) on the objective structural model (464); # - assignment of the estimated elasto-plastic parameters from response surfaces (470); # - validation of the structural model (482) by simulation of the uniaxial tensile test (484); # - manufacturing by means of a cold stamping process of the component using the structural model validated ral.
