Abstract
This paper presents a method of increasing drawability
of materials in hot stamping processes using forming
tools with macro-scale textures on the tool surfaces. Firstly, a
series of tool texture designs and orientations were presented
and a test programme was designed for the experimental investigation.
Top-hat shape drawing experiments in cold and
hot stamping conditions were conducted to evaluate the effect
of macro-scale tool surface textures on the material drawing.
Texture directional and texture feature effects of the
blankholders on the draw-ability of the material have been
investigated. A finite element model of the top-hat drawing
process with textured tool surfaces has been established and
validated from experimental data. Further FE process modelling
has been carried out and the effects of texture features and
forming speed have been studied. The relationships between
texture designs and material drawing results have been
analysed. The developed FE model can provide a guide to
design the geometry of tool textures and optimise the hot
stamping process parameters.
