dc.description.abstractIn this work a new technology for forging and the tool for its implementation - strikers with sloping faces and circular segments, are developed. The use of this technology allows to implement in the course of intense deformation the processing of metal over the entire cross section. The distribution of the stress has shown that when the deformation of the almost all section of the billet is dominated by compressive stresses, contributed to the closure of internal defects. The study of the strain state has shown that the development of the strain is on forging cross, after contact of the side edges with circular segments the deformation zones are expanding, covering the entire cross section of the workpiece. When modeling the process of closing the internal defect it is found that the decrease in the angle of the faces leads to a decrease in shear strain during drawing, resulting in the closure of the defect occurs only in a zone located at a distance of 50% of the feed value. The optimal value of the angle of the faces of the dies is equal to 30° with the angle of the through hole in the axial portion of the workpiece is completely closed. The use of the angle of inclination more than 30° is not recommended, since in this case high-rise deformation is insufficient for complete closure of the defects.
