Paper Title:
Accurate Prediction of Die Face Coloring Rate for Short-Period Manufacturing of Automotive Drawing Dies
  Abstract

In this paper, the thinning rate and die elastic deformation under large forming force are investigated by finite element simulation with experimental validation focused on the problem of coloring rate between die and panel in automotive die manufacturing. The study suggests that when the panel is formed, the thinning rate of panel has little influence on the coloring rate and the die elastic deformation under large forming force is the main influence factor. The definition of high contact pressure area is proposed by the comparison between the simulation and industrial experiment results. The definition greatly benefits the predication of die face coloring rate. The method that die face is compensated reasonably is also proposed. It can reduce the die polishing workloads obviously compared to the traditional method of die face equivalent offset. This paper has a guide for comprehensive understanding the influence factors of coloring rate and greatly reducing the die tryout period.
