Butt, Rasheed Ahmed (1994) Design of composite die for wire drawing. Masters thesis, King Fahd University of Petroleum and Minerals.
In the present work a design methodology is developed to protect brittle ceramic materials from failure during drawing operations. Analytical and Finite Element techniques are employed to study straight taper and contoured dies respectively. Variation of shrink-fit pressure is studied by systematically varying some important process parameters. It is found that area reduction and exit wire velocity significantly affect shrink-fit pressure. Effect of radial thickness is significant only for small thicknesses. Semi die angle and die length have almost no effect on shrink-fit pressure. A comparison between the analytical and Finite Element approach shows that the analytical approach produces good results for small reductions and die angles.
