Markov O. E., Zligorev V. N., Rudenko N. A., Kolyadenko A. V. Increasing quality of large forgings by using forgings schemes with intensive plastic deformation // Scientific Herald of the DSEA. – 2015. – № 2 (17Е).

Effect of wedge angle and depth of the convex dies concavity faces on closure of the axial defects and stress state in the axial zone was considered in the paper. It was found out, that increasing wedge angle and depth of concavities dies faces increases the degree of closure of the axial defects. Reduction in diameter was 25 % for flat dies, for angle 160 ° – 35 %, for angle 140 ° – more than 35 %. Angle 140 °was inefficient for obtaining four-ray workpieces with the point view of closure of axial defects. Intensive closure of defects occurs in the four-ray workpieces during reduction of 25 ... 30 % in the dies with the angle in the range 160 ... 180 °. High level of compressive stresses provides full closure of axial defects. These results are explained by index of rigidity of stress state in axial zone to form the four-ray workpiece. These data are confirmed by experimental studies.
