The polycrystalline diamond drawing die hole designed as a "straight"

Under normal circumstances the polycrystalline diamond drawing die hole designed as a "straight", the hole is divided into six regions, namely the entrance area, lubrication area, work area, sizing area, inverted cone zones, export zone, the hole structure shown in Figure 1.  abrasive grinding  diamond wire drawing die hole structure diagram Currently, there are based on one-dimensional axisymmetric statics to analyze polycrystalline diamond and metal wire force status are  Diamond blade . But in the actual drawing process, because the wire drawing die of the subject of the role of cell walls in the direction of the non-uniform three-dimensional plastic  cutting tools  of the wire within the radial flow and shear strain exists, this will inevitably result in cross-section distortion, so that the internal stress distribution was uneven. Simple one-dimensional axial static analysis does not reflect the polycrystalline diamond wire drawing dies and the force between the actual situation. In order to analyze the process of drawing wire in the internal tensile stress suffered and suffered polycrystalline diamond wire drawing die hole is equivalent to the actual state of stress.
