“…Drawing processing improves mechanical properties of metal wire and refines its grain as the main forming method. So is it a kind of lossless mode of processing that the material utilization rate is at its maximum [1]. During drawing processing, drawing force is used to forcing the metal wire through the die and reducing its cross section diameter.…”

Al2O3-TiC/Al2O3-TiC-CaF2laminated ceramic drawing die used for drawing experiment was prepared by vacuum hot pressing method. The finite element models of 45#-steel and wire drawing die were built by SolidWorks and simulation analysis of drawing process were done by FEM simulation software. The axial stress, strain distribution and drawing force during deformation were got. The microstructure of the worn drawing die was observed by scanning electron microscopy (SEM) and the composition was investigated by energy dispersive X-Ray spectroscopy (EDS). Results show that the wear conditions of Al2O3-TiC-CaF2material layers were serious than Al2O3-TiC. And because of the dragging effect, solid lubricating films formed in Al2O3-TiC-CaF2material layers covered on Al2O3-TiC material layers. The drawing die owes self-lubricating performance. Without considering friction effective on invariable zone of the drawing die, the simulation result of drawing force was smaller than the measurement value.
